tpeeification of Letters Patent. gtmm'tgfl QQ, 191,

Application filed 1T une 1111, i918. Serial. No. 239,3'20.

To all whom it may concern: Be it known that l, Josnrrr HAUK, a citizen of the United States, residing at Chi-' cage, in the: county of 'Cook and State of Illinois, have invented certain new and useful Improvements in Wire-Hoop Machines, of which the. following is a specification, reference being had therein to the accompanying drawing.

My invention relates to machines for manufacturing wire' hoops for barrels and other containers, and its primary object is to provide a machine bywhich the hoops are made and uniformly curved throughout their extent to the circular bend designed I for them in a continuous operation. A further object is to provide a'coinbined-counting and delivering mechanism by which the hoops are counted ofiin batches or bunches of any desired number upon an arm of a rezone for a new bunch or batch. In machines for making Wire hoops heretofore employed the forming devices which bend the Wire into hoo -like form-impart to the main" portion of t e wire the circular bend designed for the hoop but leave certain irregularities, especially at the lapped ends which are-spliced to form the joint, and the hoop is then lifted from the machine by the operator and placed between bending jaws to give the proper curvature to all por-' tions of the hoop including the twisted or spliced portions. These prior machines also are defective in that the hoops frequentlyare not uniform in size when made from uniform lengths of wire.

By my inventionv the hoops are made and uniformly curved throughout their extent to the bend designed for them by a continuous mechanical operation, the machine containing mechanism to transfer the spliced hoops from the hoop-forming mechanism to an expander which curves them uniformly throughout their extent, mechanism to; hold the hoops on the expander and mechanism to operate the expander, so that the manual operations of lifting the hoops from the,

machine and passing them between bendingjaws or other curving devices to conform their irregularities to the proper curvature are avoided. Also, the expander insures thatthe hoops of any given batch are uniomitted form-in size, and drops them off'aftefthey are finished. Further, the machine contains,

mechanism to count off a batch of any given number of hoops to an arm of a receiving reel, and'mechanism to periodically turn the reel to remove the batch of finished hoops from the zone of the machine and present an empty arm in this zone for a new bunch or batch.

The invention consists in the matters hereinafter described and then pointed out in the appended claims.

In the accompanying drawings which illustrate a practical application of mechanismto attain my various objects,

Figural is a view in frontelevation of a machine embodying the several features of my invention;

In the drawings the reference numeral 1 represents a suitable upright frame on which the various parts are carried, and 2 the maindrive-pulley (m shaft 3 journaled in bearings at the top of the frame andto which power is applied from any suitable source and from which it is transmitted through bevel-gears 4 and 5 to a vertical shaft 6 mounted in hearings on one side of the frame and thence by bevel-gears 7 and 8 to the main shaft 9 upon which the gear 8 is secured. The machine contains suitably driven feed-rolls 10 for feeding the wire from a coil to the hoop-former 11 having a circular raceway 11 to bend the wire into hook-like form and vertically supported upon a circular vertical plate 12 on the frame, suitable wire grippin and cutting mechanism 13, a rotating floating twister 14 confined in its circular casing 14 for twisting or splicing the lapped ends of the severed wire and having the usual radial discharge slot 15, and suitably operated hoo stripping mechanism 16, controlled by t e main shaft 9, and as these devices are old and well-known, forexample in the patent to A. F. Dice, No. 689,578, dated Dec. 24, 1901, they are shown in conventional form and require no detailed description, it being understood that the parts are so arranged that a hoop is spliced by the twister 14 and discharged by the stripper 16 at each revolution of the shaft-,9;

A curved horn 17 is fastened to the plate 12 at' its upper vertical end in alinement withthe hoop-forming raceway to receive the hoop as it is stripped from the latter,

the diameter of the horn being such that the hoop easily slides thereon. The top portions of the horn, supporting plate and on opposite sides of the horn on shafts 21 which have longitudinal reciprocating motion to shift the studs into and out of the slots and IOCkiIlg motion to cause the studs to travel down the slots and return outside the slots when their shafts are rocked while shifted inwardl and outwardly respectively. The sha ts 21 are mounted toreciprocate and rock in bearings 22 on the frame, and they are in their outwardposition when a hoop is discharged upon the upper end of the horn by the stripper 16 so that the studs 20 are in their retracted position out of their slots and out of the path of the hoop as shown in Fig. 1 to allow the hoop to pass to position on the horn beyond the path of the closing-in movement of the studs, so that the latter lie behind the hoop on the horn when they are moved into their slots. Each shaft 21 carries a collar 23 in a peripheral channel of a fixed sleeve 23 and'provided with a pair of opposite pins 24 engaged by elongated yokes 25 on the upper portion of a rocking-arm 26 keyed to the front end of a rock-shaft 27 journaled in suitable bearings on the frame and whose rear end carries a wiper-arm 28 in the path of a crown cam-wheel 29 on a shaft 30 (Fig. 5) which is rotated in unison with the rotation of shaft 9 by a sprocket-chain 31 connecting' equal sized sprocket-wheels 32 and I 33 respectively on these shafts so that the shaft 30 makes a revolution for each hoop delivered upon the horn by the strippingdevices 16. The wiper-arms 28 are held by torsion springs 34 against the cam-wheels 29 so that when the arms are in contact with the dwells of the wheels the shafts 27 are rocked by the springs to the position shown in Fig. 1 with the shafts 21 shifted outwardly and the studs 20 withdrawn from their slots 18 to allow a hoop to ass onto the horn, and the cam portions of t e wheels rock the arms 28 reversely to shift the shafts 21 inwardly and. close the arms 19 to their inner positions with their studs 20 projecting into the slots as shown. in Fig. 8 and back of the hoo on the horn, the cams being timed to close t e studs into their slots when 100 a hoop is delivered to the horn by the stripper 16 and toretain them in this osition while the arms 19 are rocked to malie their hoop-carrying downstroke in their slots and then the springs 34 reversely rock the shafts 27 to retract the shafts 21 and withdraw the studs from their slots. The rocking motion of the shafts 21 to rock the arms 19 is permitted by the collars 23 engaging the channels in the fixed sleeves 23 and is provided by each shaft carrying at its outer end a fixed pinion 35meshing with a reciprocating rack 36 which is of sufficient width to engage its pinion in both of the positions of the latter when its shaft 21 is shifted longitudinally and is reciprocated in a guide-box 37 mounted on the frame. Each rack is moved forwardly to rock its associated arm 19 upwardly to carry its stud to the top of its idle stroke by a cam-disk 38 mounted on the shaft 30 and bearing against a friction-roller 39 carried on the adjacent end of the associated rack, and is movedrearwardly to rock its associated arm 19 downwardly to make its hoop-carrying stroke by the expansion of 'acoil-spring 40 mounted on a rod 41 fixed at one end in the rack and passin freely through an abutment 42 forme by the upper end of a bracket 43 fixed at its opposite end to the tension by the .outwar memes guide-box 37, the sprihig being put under rack by its cam 38 and reactingbetween the rack and abutment to move the rack inwardly when the roller 39. enters the dwell in the cam-disk. The arms 19 are moved on their downstroke by their springs to carry the studs 20 on their downstroke in their slots 18 so that in case a hoo carried over the horn by these studs bin s on the horn the springs will yield to avoid breakage of any'of the parts. When the arms 19 are in their closed position under the influenceof the cam-wheels 29 with their studs in the upper ends of the slots 18 the dwells in the cam-disks 38 permit the springs 40 to retract the racks 36 to turn the pinions 35 and shafts 21 to rock the arms forward and downward in their slots to deliver a'hoop to the expander at the lower end of the horn, and when the arms 19 reach the end of their downstroke the springs 34 shift the shafts.

mally flush with the lower end of the horn and are then outwardly beveled as at 46.to center and level the hoop and provided with a vertical skirt 47 on which the hoop is brought to rest by the arms 19, each of the heads having a clearance passage 48 in ex w tension of the slot 18 for the stud 20 on its corresponding side of the born. The heads 45 are slidably supported on the underside of the horn; for this purpose the horn is provided with a transverse upwardly projecting central bridge 49 having a guideplate 50 secured along the base of each of its sides with its inner edge projectin into the space below the bridge as shown c early in Fig. 10, and each head 45 carries a top guide-plate 51 which slides freely between the opposite inner edges of the guides 50 providing a way therefor, and also carries on top of its guide-plate 51 a wider retainingplate 52 which fits and freely reciprocates within the bridge and whose outer edges overlie the inner edges of the guides 50. Each head has an inner central recess 45, and each guide-plate 50 has a recess 53 in extension of the corresponding recess .in its head, and a'wiper-roller 54 is carried in each recess 53 being mounted in its head and associated retaining plate 52 in the path of a double expander cam '55, which expands the heads when turned from its normal inoperative position shown in Fig. 10, and puts their return springs 45 under tension.

The expander cam is carried on the lower end of a shaft 56 rotatably mounted in cenmovement of its of a plunger 62 which is rotatably and slidably mounted in bearings 63 in a guide-box 64 fixed to the upper portion of the frame. The guide-box overhangs and is spaced above the horn and its upper portion is divided as shown in Fig. 1, its upper end being supported by a closed yoke 65 which is horizontallyelongated as shown for a purpose hereinafter" described. The plunger is reciprocated longitudinally by an open frame composed of a pair of opposite arms 66 fixed at one end to a pintle '67 mounted to rock in the frame and straddling the box 64 at their free ends where they are connected to the plunger by the links 68 which are pivoted at their upper ends to the free ends .of

the arms and at their lower ends to lateral pins 69 fixed in a collar 70 which engages the plunger to reciprocate it longitudinally but allows it to rotate or turn. The guidebox 64 is cut away on each side as shown in Figs. 2 and 3 to allow clearance. for the plunger-pins 69' when the frame is operated by its operating link 71 which is pivoted at its lower end to one of the arms of the frame and at its upper end to the'lower end of a reciprocating rod 7 2 passing up through a vertical guide 7 3 on the frame above which its free end is provided with a roller- 7 4 engaged by a crown cam-wheel 7 5 to raise and lower the frame. The cam-wheel 75 is mounted by spacin studs 76 on the upper face of the mutilate gear 77 which is keyed to the upper end of a short vertical shaft 78 mounted in a bearing 7 9 on the frame and driven by miter gears 80 and 81 from a short shaft 82 which is journaled in bearings 83 and has Y a friction-brake 84 and carries a loose bevel gear 85 constantly-rotated by a bevel-gear 86 keyed on a shaft 87 journaled in bearings 88 and having a driving pulley 89 to receive motion from any suitable source of power. The clutch members 90and 91 fixed respectively on the shaft 82 and the sleeve of the gear 85 are connected and disconnected by at its free end to the upper end of a link 96 which carries at its lower end an elongated closedyoke 97' inclosing the shaft 9 and hav-. ing a wiper-roll 98 operated by a cam 99 on I a disk 100 on the latter shaft, the clutch-pin connecting its members when the latch 93-is raised by cam 99 out 'ofthe pathof its projection and retracted when the latch is lowered into its path. The cam 99 istimed to trip the latch and allow the clutch to close to rotate the shaft 82 when the carrier-arms 19 i are at the end of their downstroke to deliver a' hoop to the expander, which occurs once for each'revolution of shaft 9, and then the shaft 78 'is rotated .to move the cam portion of the wheel 75 out of the path of the roll -74 to allow the frame 66 to lower the plunger 62 to engagethe plunger-wrench 61 with the squared endof the shaft 56, and while the parts are in this relation the mutilated driving gear-wheel 77 engages the driven gear-wheel 101 of theintermittent gear to turn the expander cam a half revolution.

The gear-wheel 101 is located in the yoke 65 and has a sleeve 102 revolubly mounted in the guide-box 64 and splined to the plunger to turn the latter but allow it to reciprocate longitudinally therein. The mutilated driving gear-wheel 77 of the intermittent gear is provided with teeth along one half of its perimeter, and its opposite half is of reduced diameter and carries a projecting: convex plate 103 which interlocks with either-concave end 104 of a locking plate" 105 fixed transversely across the top of. the driven gear 101, as shown in Fig. 15, the arrangement 'being such that during each revolution of the gear 77 its teeth turn the gear 101 a half revolution and then the plates 103 and 104 interlock and the gear 101 is locked against turning until the gear 77 again revolves, the center line of the concavity 104- of the platebeing on the center line of the teeth of thedriven gear 101 so that when the driving ear 77 is again turned its teeth mesh with t e teeth of the driven gear to turn the latter a half-revolution. Each half -revolutionof the gear 101 gives the act on the'hoop, and the parts are so related that the dwell of the camvwheel 7 5 is suffiplunger 62' a. half turn which is sufiicient 'to operate the double expander-cam 55 to move the expander heads 45 outwardly to until the cam 99 again trips the latch. Theclutch controls the expander-mechanism, and the cam 99 is timed-to close this clutch after the arms 19 are rocked down to deliver a hoop in position on the expander, and while this clutch remains closed thev cam 7 5 istimed to lower the plunger to engage its wrench wish the upper end of the cam-shaft 56, and the mutilated gear is timed to then rotate the plunger and the connected camshaft to spreadthe expander-heads'45.'

The hoops are held in position on the expander-heads by opposite supporting-plates 106 in the form of segments conforming to the curvature of the skirts 47 of the expander-heads. The plates 106 have hoopretaining wings 107 and are mounted on laterally movable rocking-arms 108 keyed on the'forward ends of transverse rock-shafts 109 which are mounted in bearings 110 on the frame and are provided at the rear ends with rocker-arms 111 each carrying at its free end a wiper-roll 112 in the path of a crown cam-wheel 113 on the shaft 30 to rock the arm 108 away from its expander-head, and a spring 114 reversely rocks the arms 108 when the rolls 112 are in the dwell of the cams, the organization of the parts being such that the spring closes the supportingplates on the expander to receive the hoop before the expander is operated and to support it while the latter is operated, and the cams then rock the plates away from the expander to allow the hoop to drop off the expander when its heads are retracted after the stroke of their cam 54. The cams 29 and 113 are respectively timed to allow the carrier-arms 19 when they have reached the end of their downstroke to be moved outwardly by their actuating springs 34 before the plates 106 are withdrawn from their position to support the hoop.

When a hoop drops off the expander it is caught by an arm of a receiving reel located below the expander. The reel is in the'form of a bifurcated yoke having arms 115 and is revolubly operated so that the arms alternately stand in the zone of the expander to receive the hoops dropping therefrom. The reel is carried on a head 116 fixed to the upper end of a shaft 11.7 revolubly mounted in a standard 118 projecting upwardly from the base-plate of the frame and rotated through miter gears 119 and 120 by a throughshaft 121 journaled in endbearing in the frame and in turn rotated through miter gears 122 and 123 by a vertical shaft 124 j ournaled in bearings 125 and in turn rotated through bevel gears 126 and 127 by a cross-shaft 128 journaled in endbearings 129 on the frame. A sprocketwheel 130 loosely mounted on the shaft 128 is constantly driven by the sprocket-chain 131 from a sprocket-wheel 132 on the shaft 30, and is coupled and uncoupled with the shaft 128 by a friction clutch to periodically rotate the latter shaft. The hub 133 of the wheel 130 carries a friction-cup whose flange 133 surrounds the flange 134 of a second cup 134 loosely mounted on the shaft and connected by coil-springs 135 to a spool 136 keyed to the shaft, and a cam-disk 137 located in the cup 134 is keyed to the shaft and engages thev rolle'i's 138 movably confined in openings in the fiange 134 the springs 135-being put under tension and the. rollers moved into the reduced portions of 2 frictional engagement with the-flange 133 and the shaft 128 is rotated. The movement of the stop-block 142 is controlled by a trip-device and counting wheel operated from the shaft 30 which makes a revolution with the shaft 9 for each hoop delivered to the expander. A worm 144 is keyed to one end of the shaft 30 and meshes with a worm- 3 wheel 145 on one end of a short shaft 146 journaled in a suitable bearing in a lateral bracket on the frame to turn the worm-Wheel 14.5 the distance of one tooth for eachrevolution of the shaft 30. The shaft 146 is provided at its other end with a fixed gearwheel 147 meshing with a gear-wheel 148 ren'iovably mounted on a stub-shaft 149 carried by an arln 150 pivoted to the frameat 151. and the gear 145 moves the distance of one toothfor each vhoop delivered, and the ratio of the gears 147 and 148 is such that they latter makes a complete revolution for a given number of hoops so delivered, say seventy-five, and by changing the ratio ofl these gears the number of hoops discharged during each revolution of the gear 145 will vary accordingly, the interchange of different gear-wheels at 148 being provided for by their removability on the stub-shaft149. Each gear-wheel 148 is a counting wheel and carries a revolving drum 152 which is providedwith a peripheral recess 153 to receive the free inwardly projecting end of'a springactuated trigger or latch 154 which is carried on one arm 155 of a bell-crank lever pivoted to freely swing on a bolt 56 which is adjustably held by lock-nut 57 in' the curved slot 158 of a sector-plate 159 which is integral with the arm 150 and is in turn adjustabl locked in position on the frame by the lock-holt160 passing through its upper curved slot 161. The opposite end 162 of thc hell-crank is connected hvan adjustable link 163 to a rock-arm 164 fixed on one end of a rock-shaft 165 journaled in the frame and carrying at its other end a fixed arm 166 which is connected by a pivoted link 16? to the socket-block 142. When the counting-gear 148 completes a revolution a number of hoops corresponding to the number of its teeth has been discharged from the expander upon the adjacent arm 115 of the 161 being The worm 144 makes one revolution expander.

receiving reel,z and the recess 153 in the drum 152 then comes into the path of the trigger 154 Which is snapped into the recess by the force of a retracting spring 168,. which is connected to the frame and the arm 164and Withdraws the stop 141 from the path-of the lug 138 to allow the clutch to couple the revolving sprocket-wheel 130 to the shaft 128 to turn. the latter for a complete revolution and throu h the ratio of the bevel gears 126 and 12 turn the reelshaft' 117a half-revolution to rotate one arm 115 with its bunch of hoops,out of the zone of theexpander and present the empty arm into position below the expander to re ceive a fresh batch of hoops. The arm 150 is provided witha handle 169 to adjust the plate 159'for counting-disks 148 of Various sizes, it being understood that the adjustment of the bell-crank 155 is correspondinglymade for the variations in the size of the associated drums 152, thelslots 158 and 'o'nfcentric, and struck on a radius Whose center is at '151. i

In theoperation of the machine, the drive shaft 9 controls the operation zof the devices to make the hoops, the stripping-mechanism 16'delivering a hoop to the horn at each revolution of the shaft, the carrier arms 19 then occupying the position shown in Fig. 1. These arms then are closed in to enter their studs in the slots behind the hoop on the horn and are rocked downwardly to carry the hoop alon the horn and deliver it to the The supporting plates 106 are closed in .totheir'position against the expander while the arms 19 are carrying the hoop along the horn, and when the hoop reaches the supporting plates the arms 19 are withdrawn from their slots to their outward position and rocked upwardly to their initial position the plates continuin to support the hooponthe expander. 1' iile the plates 106 support the hoop on the expander the cam 99 trips the latch 93 and the clutch members 90 and 91 governing the expander are coupled to rotate the cam-wheel 75 and operate the intermittent gears 7 7 and 101, so that the plunger-wrench is lowered to engage the shaft 56 andis turned to operate the expander cam the plunger-wrench then being immediately restored to its inoperative position and the supporting plates being rocked outwardly and the expander heads retracted so that the finished hoop drops from the expander upon the receiving arm 1150f the hoop-reel. For each hoop discharged on the receiving arm the shaft 30 completes a revolution and moves the counting wheel 148-one tooth, and upon the C011? pletion of the revolution of the counting wheel upon the, discharge of the number of 'hoops corresponding to the number of teeth path of the trigger 151 which is snapped therein by the spring 168 to trip the block 141 and permit the clutch 131 to couple the shaft 128 to the constantly driven sprocket 133 so thatthis shaft is revolved to turn the shaft 117 a half-revolution to swing the active receiving arm from its posltion below the expander and present an empty arm in its place to receive a new batch of completed hoops.

The horn and the skirt i7 of the expander when retracted are smaller than the hoop, and the expander is slightly oval when retracted and when expanded is circular and slightly pulls the twist or splice of the hoop' to draw the hoop to a fixed circumference. The wings 107 of the expander prevent the hoops from falling off the supporting-plates while the latter are in' position against the retracted heads of the expander.
