- the numeral 10 designates generally the main frame WlllCll 1s preferably constructed of tubingjand wh ch has-at one end a cylinder frame 11 braced by brace rods 12 and including adjustable standards 13 controlled by clamps 13 The standards 13 telescope into the vertical members of the cylinder frame 11 and by fasteningthe clips 13?
- a cross bar 14 extends a bearing 15 intermediate its ends in which a rotatable support 16 is mounted, the supper-1: 16 being rotatable on a vertical axis and having a clamp member 17 threaded on its lower end by -which it may be held rotation. if this is desired!
- Gil ' of universal A cylinder designated at 20 is provided and has a strap 21 rigidly secured to the periphery thereof, the strap 21 having downwardly extending parallel arms 22 constituting a yoke which embraces and is pivotally secured to the upper end of the rotatable support 16 by means of a horizontal pivot 23 controlled by a clamp 23.
- a second strap 24 is secured to the cylinder 20 and in spaced relation to the strap 21 and is connected with the strap 21 above the horizontal pivot 23 by means of a link 25 and exerts a bracing action.
- a piston 28 is operatively mounted in the cylinder and includes a drum 29, heads 30 and packing elements 31 adjacent each head.
- the packing elements preferably comprise leather washers and portions thereof are inserted between the drum 29 and the heads 30 to be thereby associated with the piston.
- a hollow piston rod 36 is threaded into an opening providedtherefor in one of the piston heads 30 as indicated at 37.
- the piston rod 36 operates in a stuffing box 38 provided in one of the cylinder heads and carries at its outer end a handle bar 39 slidably mounted on the piston rod by means of a sleeve connection 40.
- the sleet e 40 is slidable on the piston rod and is provided with a slot 41.
- brackets 42 are provided and carry adjustable abutments 43 which are adapted to successively engage or abut a post 44 rigidly secured to the piston rod and projecting through the slot 41 of the sleeve 40.
- a second post 45 is also carried by the piston rod and is connected with the post 44 by the rod 46 to thereby brace the post 44.
- the handle bars 39 carry loose hand grips 39 and when these hand grips are grasped and the handle bar is moved in one or the other direction it first partakes of motion relative to the piston rod the motion being in the one or the other direction accordingly as the handle bar is moved in one or the other direction. and this relative motion of the handle bar with respect to the piston tion 40 of the handle bar engages the post 44 of the piston rod. This relative motion between the sleeve and the piston rod is utilized to actuate the valve control as will presently appear.
- the short pipe 3.2 has incorporated there in a throttle valve 50 including a casing 51 having screw threaded connection with the sections 32 and 32 of the pipe 32 and a. turning plug 52 having a port 53 therein which may be brought into full registry with the sections of the-pipe 32, entirely out of registry therewith, or into any partial degree of registry therewith.
- the throttle valve controls the resistance offered to movement of the piston in either direction. It is obvious that when the throttle valve is fully opened the air may flow freely through the pipe 32 from one side of the piston to the other and no resistance is presented to the travel of the piston and that when the throttle valve is entirely closed the fluid is locked in the cylinder on the opposite side of the piston and presents the maximum degree of resistance to piston travel. Between these two extremes the resistance opposed to the piston may be greatly varied by regulating the adjustment of the throttle valve.
- the throttle valve For the purpose of varying the resistance, the throttle valve carries an operating arm 54 connected with the turning plug and having a stop pin 54 for limiting its movement.
- the free end of the operating arm 54 is pivotally secured to one end of a connecting rod 55 which slidably extends through a guide 56 carried on a bracket 57 secured to the outer end of the piston rod.
- a swinging cross head 58 is pivotally mounted on the bracket and is connected by a link 59 with the sleeve 40 of the handle bars.
- An adjustable pitman 60 is pivotally connected at one end to the rod 55 01 the Valve mechanism and is adapted to be connected at its other end to any one of the pins 61 62 or 63 on the swinging cross head.
- the pins 61 and 63 are equidistant from the center or axis of swing of the swinging crosshead and the pin 62 is alined with this axis. It is obvious that when the handle bar is grasped and actuated so as to move its sleeve 40 relative to the piston red as previously described, the motion of the sleeve is transmitted to the connecting rod 55 and to the throttle valve 50 by means of the link 59, the swinging cross head and the adjustable pitman 60 provided the ad justable pitman in connected with either the pin 61 or the pin 63. It the adjustable pitman 60 is connected with the pin 61 as shown in full lines in Figure 4, the motion of the sleeve of the handle bar is transmitted reversed to the connecting rod 55 and on the other hand it the adjustable pitman 60 is connected with the pin 63, the
- a three-way valve is incorporated in' the pipe havingscrew threaded connection with the sections 33 and 83*. thereof and includes a 'valve casing 66 having an outlet port 67 which communicates with the connection'68 to a register or indicatorzpipe 69.
- the register or indicator pipe 69 extends through the hollow piston rod and t-hroughtheouter endthereof and carries a pressure gage or register 70 at its outer endf
- a turning plug 71 is rot'atably arranged and is provided with an angular. port 72 extending therethrough.
- An operating arm 73 is connected with the plug- 71 and bymanipulating this arm the plug may be turned to bring its port into register with either of the sections of the pipe 33 and with the outlet port 67 of the valve casing; In this manner the register or gage pipe may be connected with one side or the A stop pin 73 1S carried by the operating arm 73 and limits the. movement of the arm.
- An "operating rod 76 is pivotally connected at one end to tit) the operating lever 73 and extends through the hollow piston rod and exteriorly thereof terminatingin a handle 77.
- the rod 76 slidably extends through.
- the guide 78 in whichis incorporated a clamp screw 79 for securing the rod in adjusted position.
- a sliding seat is arranged on the frame 10 and includes a seat frame 81 having rollers 82 and a seat proper 83 having an am ss ad- I justably nounted i'na bearing 85 carried by the sea frame.
- the rollers 82' of the seat frame operate on tracks 82 carried on the floor of the main frame and, in this manner the seat 80 serves as aslldlng seat.
- a foot rest designated generallyat 86, is provided and includes a base '87 having studs 88 at its end adapted to be received in sockets 89 provided therefor on the main frame.-
- the "frame ofithe foot rest is mounted on the base 87 nearer to one end than to the other so that by reversing the' base 87 the distance the'foot rest from its seat maybe varied.
- the frame of the foot rest includes a post 89 upon which a sl ev 0 is, meta, wa ed i I' QP 91 is associated with sleeve and" has a hook 106 carried by the chain bifurcated arm 92 adapted to be engaged over the base 87 to prevent rotation of the sleeve 90 on the post 89 when the clamp is set to grip the sleeve.
- the sleeve 90 At its upper end the sleeve 90 carries a cross bar 93 which carries a foot plate 95 by means of a bracket 96, the bracket having hooks 97 engageabie with the cross bar and having turn buckles 9.8 for varying the inclination of the foot plate.
- the foot plate includes heel plates 100 and toe straps 101.
- Means is provided for securing the seat 80 stationary when desired and includes a flexible element such as a chain and a V and engageable with the foot rest.
- the person using the machine may either stand or sit, the machine "being adapted for either by adjusting the standards 13. IVhen sitting, use is made of the sliding seat 80 and the footrest 86.
- the feet may be placed upon the foot plate 95 or'the calves of the legs may be engaged with the cross bar 93, the'latter beingpre-ferable when the valve control is set so as to present resistance to inward travel of the piston.
- the person using the machine grasps the grips 39 of the handle bar and rcciprocates the piston against the resistancepresented by the fluid in'the cylinder.
- valve control may be set so as to cause the piston to encounter any desired degree of resistance in travelling inwardly oroutwardly or in travelling in both directions by an adjustment of the abutments i and adjustable pitman 60.
- these ad ustable abutments may beset to engage the stationary abutment or post 44 at all times, and 'thus entirely prevent actuationof the throttle valve, thus maintaining the throttle valve entirely opened or entirely closed accordingly as it is desired to have maximum or minimum resistance.
- one of the adjustable abutments may be set "cisely the same as in the embodiment above described, As shown in Figure 11 asingle short pipe or intake tube extends through the piston head.
- the intake tube is made up of anumber of sections 110 110", 110 and 110.
- Centrally of the pipe 110 and connected with the sections 110 and 110 is a three-way distributing valve 111
- a check pipe 112 having incorporated therein check valves 113 and 114: is connected with the intake pipe by means of short pipe connections 115 and 116 and is also connected with the distributing valve 111 by means of a pipe connection 111'.
- a throttle pipe 118 is connected at one end with one end 01 the check pipe 112, and with the pipe 116 by means of a T 119 and at its other end the throttle pipe is connected with the opposite end of the check pipe and with the pipe 115 by means of a T 120.
- a throttle valve or resistance regulating valve 121 is incorporated in the throttle pipe 118.
- the distributing valve 111 is provided with an operating arm 122 and an operating rod 123 which slidab y extends through a bearing 121 provided therefor in the piston rod, a clamp screw 125 being threaded through the piston rod and engageable with the operating rod 123 for securing the discharge valve in adjusted position.
- the throttle valve or resistance regulating valve 121 is provided with an operating arm 126 connected with an operating rod 127 journaled in the bearing 128 of the piston rod and havin a clamp screw 129 cooperable therewith for maintaining the throttle valve in adjusted position.
- An indicator pipe 130 is connected with the intake pipe 110 and is provided with a three-way valve 131 whereby the in theater may be connected with one side or the other of the piston.
- the three-way valve 131 is provided with an operating arm 132 connected with an operating rod 133 slidably journaled in a bearing 13 1 provided therefor in the piston and having a clamp screw 135 cooperable therewith and retaining this valve in adjusted position.
- the distributing valve 111 is set to es tahlish con'imunication between the section 116 of the intake pipe and the pipe 117 and the throttle valve is set to present the required resistance to the passage of the lluid, the piston on the inward stroke does not encounter resistance as the fluid coming in through the pipe 110 passes through the distributing valve 111 and the pipe 117 into the check pipe 112 and through the check valve 113 and pipe 115, out through the section 110 of the intake pipe.
- the fluid enters the section 110 01 the intake pipe and passes up through the pipe 115 into the throttle pipe, since the distributing valve 111 and check valve 113 are closed to the fluid when coming in this direction.
- the fluid is thus constrained to pass through the throttle valve where in its flow is retarded to the desired degree thus presenting the desired resistance to the outward travel of the piston.
- the distributing valve 111 is set to establish communication between the section 110 of the intake pipe and the pipe 117, and the throttle valve 121 is set to pre sent the desired degree of resistance the piston encounter resistance on the inward stroke since the fluid is then constrained to pass through the throttle valve but does not encounter any resistance on the outer stroke since the fluid then passes from one side of the piston through the distributing valve and check valve 111 to the other side of the piston.
- the throttle valve 121 is set to pre sent the desired degree of resistance the piston encounter resistance on the inward stroke since the fluid is then constrained to pass through the throttle valve but does not encounter any resistance on the outer stroke since the fluid then passes from one side of the piston through the distributing valve and check valve 111 to the other side of the piston.
- the other features of the machines are identical with those 01 the embodiment above described except that the connection bet veen the handle bars
- FIG 13 there is shown a slight modified means for controlling the fluid to vary the resistance presented to the movement of the piston.
- the cylinder is designated at 138 and includes cylinder heads 139 and 1-10.

- An indicator pipe 144 is also extended through the piston head and is provided with a three-way valve 1&5 having a valve control rod 1 15 whereby the indicator may be connected with every working chamber of the cylinder.
- Pipes, designated at 1% and 1 17 are threaded into the cylinder heads 139 and 110, respectively.
- the pipe 1 16 has a throttle valve or resistance regulating valve 148 and a check valve 149 associated therewith and similarly the pipe 1 1'? has a second throttle valve or resistance regulating valve 150 and a second check valve 151 associated therewith.
- shut off valve 1&3 When the shut off valve 1&3 is closed and both throttle valves 1 18 and 150 are closed the air is locked in the cylinder and the piston encountersmaximu n resistance.
- this shut off valve When this shut off valve is open with the throttle valves closed or when the shut oil valve is closed and both. throttlevalves are open, the pistonencounters minimum or practically no resistance. If it is desired to present resistance to the inward travel of the piston the shut off valve 142 is closed and the throttle valve is closed to the desired degree. Then when the piston is pushed inwardly the air or other fluid being retarded inits escape through the throttle valvelfiOopposes the inward motion of the piston, the air being permitted to flow into the other side of the piston through the check valve .149.
- FIG. 15 is shown another modified form of ineans for controlling the flow of. the fluid to vary theresistance.
- a pipe 156 extends and constitutes a combined throttle pipe and indicator pipe, a throttle valve 157 being in;
- a check valve 160 also extends through the piston and the ends thereof are formed to constitute valve seats with which the check valves 162 and 163 coact.
- the check valves 162 and 163 are provided with stems 164 and 165, re spectively, which are slidably mounted in bearings 166 and 167 provided therefor in the sliding cross head 169, the cross head bein controlled by a rod 170 extendingoutwardly through the. piston rod tothe ex terior.
- the cylinder mounting shown in Figures 16 and 17 comprises a bearing 175 incorporated in the cross bar 14 inrthe same manner in which the bearing 15'is incorporated in this cross bar, as previously described.
- This bearing 175 has a vertical socket 176 and a horizontal socket 177.
- A. rotatable supporting rod 178 is adapted to be selectively mounted in either the sockets 176 or 177, and in thearrangement shown the rod is mounted in the socket 176.
- This rotatable supporting rod is provided adjacent its upper end with an annular flange or collar 179 which engages the upper end of the socket 176 and the lower end of the rod is externally threaded, as at 180. and is adapted to he engaged with a clamping nut 18.1 having a handle 182.
- a substantially U-shaped frame 183 is provided and is supported upon the upper end of the rod 178; this rod178 having a reducedextension 184 which extends through anopening 185 provided in the frame 183, the reduced extension defining on the rod 178 a shoulder 186' upon whichthe frame 183 is supported.
- a nut 187 is engaged with the reduced extension 184 and clamps the frame 183 in position on the rod 178.
- the frame 183 includes a pair 01'- spaced and parallel arms 188 which although extending upwardly from the base of the frame are not vertical but are inc'lined as shown in Figure 17.
- the nuts 183 and 193 may be tightened to hold the cylinder stationary.
- the inclination of the arms 188 enables the operator to use the device with the cylinder arranged horizontally or vertically as he may desire. Moreover if it is not convenient to take advantage of the inclination of the arms 188 to use the device with the cylinder vertical, then the supporting rod 17 8 may be engaged with a socket 17 7 intead of with the socket 176 so that the cylinder will be supported in substantially a vertical position.
- the piston is designated at 195 and has connected thereto the tubular piston rod 196, to the outer end of which the handle bars are connected through the sleeve connection 197, this sleeve connection having limited movement on the piston rods,
- a pipe 198 extends through the heads of the piston and has incorporated therein a throttle or resistance regulating valve 199, the stem of which valve has rigidly connected thereto a gear 200.
- a second valve gear 201 meshes with the gear 200 and is fixed to one end of the rotatable valve controlled rod 202 supported for rotary movement in a bracket 203 carried by one of the piston heads.
- the collars 204 are fixed to the rod 202 and engage the opposite sides of the bracket 203 to prevent longitudinal displacement of the rod 202.
- This rod 202 extends out through the piston rod 196, and to the outer end of this rod a curved plate 205 is adjustably connected by means of an angular arm 206 and a pair of nuts 207 having threaded connection with the rod and engaging the opposite sides of the arm 206.
- This curved plate 205 nests in or is snugly fitted against a second curved plate 208 rigidly supported upon one arm of the U-shaped bracket 209, the other arm of which bracket is rigidly connected to the sleeve 197 of the handle bars.
- the plate 205 is provided with cam slots 210 and 211.
- the cam slots being of opposite throw and being adapted to selectively cooperate with a pin 212, the pin having a smooth shank 213 adapted to operatively engage either one of the slots 210 and 211 and the pin also having a threaded portion 214 adapted to be engaged with threaded sockets 216 and 217 provided in the plate 208 and underlying the slots 210 and 211, respectively.
- the sleeve connection 197 will first move relative to the tubular piston rod 196.
- This relative movement is limited in any convenient manner and may be limited after the manner shown in conjunction with either types of valve control but in any event this relative movement is utilized to actuate the valve shifting or control mechanism since as the sleeve connection 197 moves it carr es with it the bracket 209 which being connected to the plate 208 will cause the plate 208 to move and carry with it the pin 212.
- This movement or the pin 212 of the plate 208 is relative to the plate 205 and its cam slots since the plate 205 is carried on the rod 202 which is held against longitudinal move- J I ment with respect to the piston and piston rod.
- the movement of the pin 212 relative to the slot 210 or 211 as the case may be imparts to the plate 205 a rotary movement so that the valve operating rod 202 is rotated when the valve 199 is moved through the instrumentality of the gears 201 and 200. It is obvious that when the pin 212 is engaged with the slot 210 the valve will be moved in one direction whereas when it is moved in engagement with the slot 211 the valve will be moved in the opposite direction. Any desired ratio may be had between the gears 201 and 200 to provide for the proper degree of movement being imparted to the valve 199.
- valve acts as an intake valve as the piston travels in the direction in which no resistance-is desired and the same valve serves as a resistance regulating valve as the piston travels in the direction in which resistance is desired.

I the numeral 10 designates generally the main frame WlllCll 1s preferably constructed of tubingjand wh ch has-at one end a cylinder frame 11 braced by brace rods 12 and including adjustable standards 13 controlled by clamps 13 The standards 13 telescope into the vertical members of the cylinder frame 11 and by fasteningthe clips 13? at various points on the stand the extent to which the standards telescope into the members 11 and consequently the vertical adjustments of the standards may bevaried, ,Of course it is to to the standards 13 and being engageable with the upper ends of the members 11 limit the downward movement of thestandards A cross bar 14 extends a bearing 15 intermediate its ends in which a rotatable support 16 is mounted, the supper-1: 16 being rotatable on a vertical axis and having a clamp member 17 threaded on its lower end by -which it may be held rotation. if this is desired! Gil ' of universal A cylinder designated at 20, is provided and has a strap 21 rigidly secured to the periphery thereof, the strap 21 having downwardly extending parallel arms 22 constituting a yoke which embraces and is pivotally secured to the upper end of the rotatable support 16 by means of a horizontal pivot 23 controlled by a clamp 23.
When the clamp members 17 and 23 are adjusted to permit free rotation of the support 16 the cylinder is universally mounted on the cylinder frame and is free to partake motion thereon. A second strap 24 is secured to the cylinder 20 and in spaced relation to the strap 21 and is connected with the strap 21 above the horizontal pivot 23 by means of a link 25 and exerts a bracing action.
A piston 28 is operatively mounted in the cylinder and includes a drum 29, heads 30 and packing elements 31 adjacent each head. The packing elements preferably comprise leather washers and portions thereof are inserted between the drum 29 and the heads 30 to be thereby associated with the piston. Short pipes, designated at 32 and 33 and each including sections 32 and 32 and 33 and 33 respectively, ex-
tend through the piston at dian'ietrically opposite points and the ends of the pipes project beyond the heads of the pistons, these projecting ends being threaded and having mounted thereon nuts 34 and 35, respectively, which not only serve to secure the pipes in position but also serve to maintain the elements of the piston in assembly.
A hollow piston rod 36 is threaded into an opening providedtherefor in one of the piston heads 30 as indicated at 37. The piston rod 36 operates in a stuffing box 38 provided in one of the cylinder heads and carries at its outer end a handle bar 39 slidably mounted on the piston rod by means of a sleeve connection 40. The sleet e 40 is slidable on the piston rod and is provided with a slot 41. At the ends of the slot 41 brackets 42 are provided and carry adjustable abutments 43 which are adapted to successively engage or abut a post 44 rigidly secured to the piston rod and projecting through the slot 41 of the sleeve 40. A second post 45 is also carried by the piston rod and is connected with the post 44 by the rod 46 to thereby brace the post 44. The handle bars 39 carry loose hand grips 39 and when these hand grips are grasped and the handle bar is moved in one or the other direction it first partakes of motion relative to the piston rod the motion being in the one or the other direction accordingly as the handle bar is moved in one or the other direction. and this relative motion of the handle bar with respect to the piston tion 40 of the handle bar engages the post 44 of the piston rod. This relative motion between the sleeve and the piston rod is utilized to actuate the valve control as will presently appear.
The short pipe 3.2 has incorporated there in a throttle valve 50 including a casing 51 having screw threaded connection with the sections 32 and 32 of the pipe 32 and a. turning plug 52 having a port 53 therein which may be brought into full registry with the sections of the-pipe 32, entirely out of registry therewith, or into any partial degree of registry therewith. In this way the throttle valve controls the resistance offered to movement of the piston in either direction. It is obvious that when the throttle valve is fully opened the air may flow freely through the pipe 32 from one side of the piston to the other and no resistance is presented to the travel of the piston and that when the throttle valve is entirely closed the fluid is locked in the cylinder on the opposite side of the piston and presents the maximum degree of resistance to piston travel. Between these two extremes the resistance opposed to the piston may be greatly varied by regulating the adjustment of the throttle valve.
For the purpose of varying the resistance, the throttle valve carries an operating arm 54 connected with the turning plug and having a stop pin 54 for limiting its movement. The free end of the operating arm 54 is pivotally secured to one end of a connecting rod 55 which slidably extends through a guide 56 carried on a bracket 57 secured to the outer end of the piston rod. A swinging cross head 58 is pivotally mounted on the bracket and is connected by a link 59 with the sleeve 40 of the handle bars. An adjustable pitman 60 is pivotally connected at one end to the rod 55 01 the Valve mechanism and is adapted to be connected at its other end to any one of the pins 61 62 or 63 on the swinging cross head. The pins 61 and 63 are equidistant from the center or axis of swing of the swinging crosshead and the pin 62 is alined with this axis. It is obvious that when the handle bar is grasped and actuated so as to move its sleeve 40 relative to the piston red as previously described, the motion of the sleeve is transmitted to the connecting rod 55 and to the throttle valve 50 by means of the link 59, the swinging cross head and the adjustable pitman 60 provided the ad justable pitman in connected with either the pin 61 or the pin 63. It the adjustable pitman 60 is connected with the pin 61 as shown in full lines in Figure 4, the motion of the sleeve of the handle bar is transmitted reversed to the connecting rod 55 and on the other hand it the adjustable pitman 60 is connected with the pin 63, the
other of the cylinder.
point of connection of the adjustable pitman GOthen lies in the axis of swing of the cross head 58. It is: apparent that the moiiement of the conn cting rod is transmitted to the plug of the throttle valve by means of the operating arm 54 and thus serves to control this-valve A three-way valve is incorporated in' the pipe havingscrew threaded connection with the sections 33 and 83*. thereof and includes a 'valve casing 66 having an outlet port 67 which communicates with the connection'68 to a register or indicatorzpipe 69. The register or indicator pipe 69 extends through the hollow piston rod and t-hroughtheouter endthereof and carries a pressure gage or register 70 at its outer endf In the valvecasing 66 of the threeway valve, a turning plug 71 is rot'atably arranged and is provided with an angular. port 72 extending therethrough. An operating arm 73 is connected with the plug- 71 and bymanipulating this arm the plug may be turned to bring its port into register with either of the sections of the pipe 33 and with the outlet port 67 of the valve casing; In this manner the register or gage pipe may be connected with one side or the A stop pin 73 1S carried by the operating arm 73 and limits the. movement of the arm. An "operating rod 76 is pivotally connected at one end to tit) the operating lever 73 and extends through the hollow piston rod and exteriorly thereof terminatingin a handle 77. The rod 76 slidably extends through. the guide 78 in whichis incorporated a clamp screw 79 for securing the rod in adjusted position.
A sliding seat,designated generally at 80, is arranged on the frame 10 and includes a seat frame 81 having rollers 82 and a seat proper 83 having an am ss ad- I justably nounted i'na bearing 85 carried by the sea frame. 'The rollers 82' of the seat frame operate on tracks 82 carried on the floor of the main frame and, in this manner the seat 80 serves as aslldlng seat.
A foot rest, designated generallyat 86, is provided and includes a base '87 having studs 88 at its end adapted to be received in sockets 89 provided therefor on the main frame.- The "frame ofithe foot rest is mounted on the base 87 nearer to one end than to the other so that by reversing the' base 87 the distance the'foot rest from its seat maybe varied. The frame of the foot rest includes a post 89 upon which a sl ev 0 is, meta, wa ed i I' QP 91 is associated with sleeve and" has a hook 106 carried by the chain bifurcated arm 92 adapted to be engaged over the base 87 to prevent rotation of the sleeve 90 on the post 89 when the clamp is set to grip the sleeve. At its upper end the sleeve 90 carries a cross bar 93 which carries a foot plate 95 by means of a bracket 96, the bracket having hooks 97 engageabie with the cross bar and having turn buckles 9.8 for varying the inclination of the foot plate. The foot plate includes heel plates 100 and toe straps 101.
Means is provided for securing the seat 80 stationary when desired and includesa flexible element such as a chain and a V and engageable with the foot rest.
In operation, the person using the machine may either stand or sit, the machine "being adapted for either by adjusting the standards 13. IVhen sitting, use is made of the sliding seat 80 and the footrest 86. In using the foot rest, the feet may be placed upon the foot plate 95 or'the calves of the legs may be engaged with the cross bar 93, the'latter beingpre-ferable when the valve control is set so as to present resistance to inward travel of the piston. In any event the person using the machine grasps the grips 39 of the handle bar and rcciprocates the piston against the resistancepresented by the fluid in'the cylinder. If the sliding seat and the foot rest aremade use of and the valve control is set to present resistance to the outwardmovement of the piston, a body swing, leg drive and arm movement may be availed of in moving the piston. The valve control may be set so as to cause the piston to encounter any desired degree of resistance in travelling inwardly oroutwardly or in travelling in both directions by an adjustment of the abutments i and adjustable pitman 60. As may be seen in Figures 3, at and 5, these ad ustable abutments may beset to engage the stationary abutment or post 44 at all times, and 'thus entirely prevent actuationof the throttle valve, thus maintaining the throttle valve entirely opened or entirely closed accordingly as it is desired to have maximum or minimum resistance. 7 On the other hand,
one of the adjustable abutments may be set "cisely the same as in the embodiment above described, As shown in Figure 11 asingle short pipe or intake tube extends through the piston head. The intake tube is made up of anumber of sections 110 110", 110 and 110. Centrally of the pipe 110 and connected with the sections 110 and 110 is a three-way distributing valve 111 A check pipe 112 having incorporated therein check valves 113 and 114: is connected with the intake pipe by means of short pipe connections 115 and 116 and is also connected with the distributing valve 111 by means of a pipe connection 111'. A throttle pipe 118 is connected at one end with one end 01 the check pipe 112, and with the pipe 116 by means of a T 119 and at its other end the throttle pipe is connected with the opposite end of the check pipe and with the pipe 115 by means of a T 120. A throttle valve or resistance regulating valve 121 is incorporated in the throttle pipe 118. The distributing valve 111 is provided with an operating arm 122 and an operating rod 123 which slidab y extends through a bearing 121 provided therefor in the piston rod, a clamp screw 125 being threaded through the piston rod and engageable with the operating rod 123 for securing the discharge valve in adjusted position. The throttle valve or resistance regulating valve 121 is provided with an operating arm 126 connected with an operating rod 127 journaled in the bearing 128 of the piston rod and havin a clamp screw 129 cooperable therewith for maintaining the throttle valve in adjusted position. An indicator pipe 130 is connected with the intake pipe 110 and is provided with a three-way valve 131 whereby the in theater may be connected with one side or the other of the piston. The three-way valve 131 is provided with an operating arm 132 connected with an operating rod 133 slidably journaled in a bearing 13 1 provided therefor in the piston and having a clamp screw 135 cooperable therewith and retaining this valve in adjusted position.
In operation with this embodiment of the invention, when the distributing valve 111 and the throttle valve 121 are closed, the piston encounters a maximum resistance since the fluid is locked in the cylinder and cannot pass through the piston. On the other hand, when two valves are open, the
fluid trecly passes through the cylinder and the minimum resistance is encountered. lVhen the distributing valve 111 is set to es tahlish con'imunication between the section 116 of the intake pipe and the pipe 117 and the throttle valve is set to present the required resistance to the passage of the lluid, the piston on the inward stroke does not encounter resistance as the fluid coming in through the pipe 110 passes through the distributing valve 111 and the pipe 117 into the check pipe 112 and through the check valve 113 and pipe 115, out through the section 110 of the intake pipe. 011 the outward stroke of the piston, the fluid enters the section 110 01 the intake pipe and passes up through the pipe 115 into the throttle pipe, since the distributing valve 111 and check valve 113 are closed to the fluid when coming in this direction. The fluid is thus constrained to pass through the throttle valve where in its flow is retarded to the desired degree thus presenting the desired resistance to the outward travel of the piston. li hen the distributing valve 111 is set to establish communication between the section 110 of the intake pipe and the pipe 117, and the throttle valve 121 is set to pre sent the desired degree of resistance the piston encounter resistance on the inward stroke since the fluid is then constrained to pass through the throttle valve but does not encounter any resistance on the outer stroke since the fluid then passes from one side of the piston through the distributing valve and check valve 111 to the other side of the piston. In this form of the invention it is not necessary to provide any automatic valve operating mechanism since after the throttle valve and the eiuid distributing valve are set the control of the fluid is therefore efi'ected automatically. The other features of the machines are identical with those 01 the embodiment above described except that the connection bet veen the handle bars and the piston rod may be rigid and that the automatically operating valve is dispensed with.
In Figure 13 there is shown a slight modified means for controlling the fluid to vary the resistance presented to the movement of the piston. In this form the cylinder is designated at 138 and includes cylinder heads 139 and 1-10. The piston which is identical in construction with the form of the invention shown in Figures 1 to 6, is designated at 1 10 and is reciprocable in the cylinder 138. A piston rod 14.1 is operatively connected with the piston. An intake tube 1 1-2 extends through the piston 1 10 and has incorporated therein a shut-off valve 143 having a valve control rod 1413. An indicator pipe 144: is also extended through the piston head and is provided with a three-way valve 1&5 having a valve control rod 1 15 whereby the indicator may be connected with every working chamber of the cylinder. Pipes, designated at 1% and 1 17 are threaded into the cylinder heads 139 and 110, respectively. The pipe 1 16 has a throttle valve or resistance regulating valve 148 and a check valve 149 associated therewith and similarly the pipe 1 1'? has a second throttle valve or resistance regulating valve 150 and a second check valve 151 associated therewith.
In operation with this embodiment of the invention when the shut off valve 1&3 is closed and both throttle valves 1 18 and 150 are closed the air is locked in the cylinder and the piston encountersmaximu n resistance. When this shut off valve is open with the throttle valves closed or when the shut oil valve is closed and both. throttlevalves are open, the pistonencounters minimum or practically no resistance. If it is desired to present resistance to the inward travel of the piston the shut off valve 142 is closed and the throttle valve is closed to the desired degree. Then when the piston is pushed inwardly the air or other fluid being retarded inits escape through the throttle valvelfiOopposes the inward motion of the piston, the air being permitted to flow into the other side of the piston through the check valve .149. When the piston is moved outwardly the air escapes freely through the throttle valve 148 since this is fully opened. To havev the piston moved outwardly against resistance and fully inwardly,ythe throttlevalve 150 is open and the throttle valve 148 is closed to the desired degree. -Thepartially closed throttle valve. 148 retards the-discharge of the air when the piston is moved outwardly and causes a pressure to be built up against the pistonto produce the desired resistance. 1
In Figure 15 is shown another modified form of ineans for controlling the flow of. the fluid to vary theresistance. In this embodiment the plstonisdesignated at and through the piston a pipe 156 extends and constitutes a combined throttle pipe and indicator pipe, a throttle valve 157 being in;
corporated in thepipe and a three-way valve 158 being incorporated in the bypass 159 provided in the pipe 156 and extending around the throttle pipe 157. A check valve 160 also extends through the piston and the ends thereof are formed to constitute valve seats with which the check valves 162 and 163 coact. The check valves 162 and 163 are provided with stems 164 and 165, re spectively, which are slidably mounted in bearings 166 and 167 provided therefor in the sliding cross head 169, the cross head bein controlled by a rod 170 extendingoutwardly through the. piston rod tothe ex terior. Nuts 168 and 168? are threaded on the ends of the stems 164 and 165, r espec v tively, and limit the relative movement between the bearings 1 66 and 167 and the stems 164 and 165, respectively Springs 171 and 172 are arranged on the stems 164 and 165,.respectively thesprings engaging the check valves at one end and the bearings at the other sliding the cross head 169 in one direction, that is to the right in Figure '15, the check valve .162 is seated against its seat under the light spring tension of the spring 171 and by the same movement the check valve 163 is unseated. Then when the piston moves inwardly ofthecylinder it, encounters no resistance since the fluid flows from one side the tube 160 that the fluid must flow through the throttle valve 156 and thus be retarded by the valve 157 to build up the pressure, to produce the desired resistance.
Referring now to Figures 16to 18, inclusive, it will be seen that there is shown in these figures a modified form of cylinder mounting in conjunction with a modified form of valve control. it is to'be understood however that the form of cylinder mounting shownin these figures may be utilized with either forms of valve control and also that the valve control may be utilized with either forms of cylinder mounting.
The cylinder mounting shown in Figures 16 and 17 comprisesa bearing 175 incorporated in the cross bar 14 inrthe same manner in which the bearing 15'is incorporated in this cross bar, as previously described. This bearing 175 has a vertical socket 176 and a horizontal socket 177. A. rotatable supporting rod 178 is adapted to be selectively mounted in either the sockets 176 or 177, and in thearrangement shown the rod is mounted in the socket 176. i This rotatable supporting rod is provided adjacent its upper end with an annular flange or collar 179 which engages the upper end of the socket 176 and the lower end of the rod is externally threaded, as at 180. and is adapted to he engaged with a clamping nut 18.1 having a handle 182. hen the clamping nut 180 is tightened up the supporting rod 178 isv heldagainst movement. A substantially U-shaped frame 183 is provided and is supported upon the upper end of the rod 178; this rod178 having a reducedextension 184 which extends through anopening 185 provided in the frame 183, the reduced extension defining on the rod 178 a shoulder 186' upon whichthe frame 183 is supported. A nut 187 is engaged with the reduced extension 184 and clamps the frame 183 in position on the rod 178. The frame 183 includes a pair 01'- spaced and parallel arms 188 which although extending upwardly from the base of the frame are not vertical but are inc'lined as shown in Figure 17. Adjacent the upper end of the arms 188 bearings 189 are formed and rotatably receive trunnions 190 formed on the outer ends of the cylinder clamp members 191, said clamp members being. bolted. to each other and being clamped to the cylinder, as at 192. The trunnions In this connection.
' is mounted toruniversal movement and accordingly as one or the other of the nuts is loosened it is mounted upon a horizontal or vertical axis. Also the nuts 183 and 193 may be tightened to hold the cylinder stationary. The inclination of the arms 188 enables the operator to use the device with the cylinder arranged horizontally or vertically as he may desire. Moreover if it is not convenient to take advantage of the inclination of the arms 188 to use the device with the cylinder vertical, then the supporting rod 17 8 may be engaged with a socket 17 7 intead of with the socket 176 so that the cylinder will be supported in substantially a vertical position.
In the form of the invention shown in Figures 16 to 18, the piston is designated at 195 and has connected thereto the tubular piston rod 196, to the outer end of which the handle bars are connected through the sleeve connection 197, this sleeve connection having limited movement on the piston rods,
as in the other embodiments of the invention,
and this movement being utilized to actuate the valve shitting or controlling mechanism as before. A pipe 198 extends through the heads of the piston and has incorporated therein a throttle or resistance regulating valve 199, the stem of which valve has rigidly connected thereto a gear 200. A second valve gear 201 meshes with the gear 200 and is fixed to one end of the rotatable valve controlled rod 202 supported for rotary movement in a bracket 203 carried by one of the piston heads. The collars 204 are fixed to the rod 202 and engage the opposite sides of the bracket 203 to prevent longitudinal displacement of the rod 202. This rod 202 extends out through the piston rod 196, and to the outer end of this rod a curved plate 205 is adjustably connected by means of an angular arm 206 and a pair of nuts 207 having threaded connection with the rod and engaging the opposite sides of the arm 206. This curved plate 205 nests in or is snugly fitted against a second curved plate 208 rigidly supported upon one arm of the U-shaped bracket 209, the other arm of which bracket is rigidly connected to the sleeve 197 of the handle bars. The plate 205 is provided with cam slots 210 and 211. The cam slots being of opposite throw and being adapted to selectively cooperate with a pin 212, the pin having a smooth shank 213 adapted to operatively engage either one of the slots 210 and 211 and the pin also having a threaded portion 214 adapted to be engaged with threaded sockets 216 and 217 provided in the plate 208 and underlying the slots 210 and 211, respectively.
It is obvious that when the handle bars are grasped and moved in either direction, the sleeve connection 197 will first move relative to the tubular piston rod 196. This relative movement is limited in any convenient manner and may be limited after the manner shown in conjunction with either types of valve control but in any event this relative movement is utilized to actuate the valve shifting or control mechanism since as the sleeve connection 197 moves it carr es with it the bracket 209 which being connected to the plate 208 will cause the plate 208 to move and carry with it the pin 212. This movement or the pin 212 of the plate 208 is relative to the plate 205 and its cam slots since the plate 205 is carried on the rod 202 which is held against longitudinal move- J I ment with respect to the piston and piston rod. The movement of the pin 212 relative to the slot 210 or 211 as the case may be imparts to the plate 205 a rotary movement so that the valve operating rod 202 is rotated when the valve 199 is moved through the instrumentality of the gears 201 and 200. It is obvious that when the pin 212 is engaged with the slot 210 the valve will be moved in one direction whereas when it is moved in engagement with the slot 211 the valve will be moved in the opposite direction. Any desired ratio may be had between the gears 201 and 200 to provide for the proper degree of movement being imparted to the valve 199.
It is obvious that with the exercising apparatus hereinabove described the operator or person indulging in the exercise can put on the various forms of floor calisthenics by removing the seat, the foot rest and its base, thus clearing the platform from all obstructions to lie down. As shown in the drawing and description of the automatic valve control by means of the cross head, pitman and sliding connecting rod the pitman may be placed on the pin in alinement with the axis of the cross head and clamped there after the valve has been set as desired. This makes possible the development of the same resistance by piston travel in either direction. This principle is cared for in the rotary connecting rod and valve gear arrangement by placing the pin 212 in a socket in the cap on the outer end of the piston rod. ere it acts as a set screw to prevent any rotation of the connecting rod after the valve has been set to produce the desired resist ance to piston travel in either direction.
t is to be understood that with the spring messes so asto allow the fluid to pass under it when i resistance is desired, this arrangement being maintained by having a set screw act as a clamp on the rod controlling-the head. In this manner the valve acts as an intake valve as the piston travels in the direction in which no resistance-is desired and the same valve serves as a resistance regulating valve as the piston travels in the direction in which resistance is desired. 7
It is also to be understood that an air cock attached to the outer end of the indicating tube will provide forv changing the air in the cylinder. V
