TO THE EATON MANUFACTURING COMPANY, OF CLEVELAND, OHIO, A CORPORA- TION OF OHIO ROLLING MACHINE This invention relates to machines for rolling round rods and bars and has for one of its objects, the provision of a machine that will be adapted to roll various diameters of rods and bars accurately to a finished size.

A further object of the invention is to provide a machine, of the type referred to, that will be capable of rolling rods and bars at high speed and not only provide a product that is accurate as to diameter but that will also be straight and automatically cut to uniform predetermined lengths.

A further object of the invention is to provide a machine, of the type referred to, that will roll the metal of the rod or bar circumferentially and thereby produce a finish of high quality, and be capable of working the metal cold in such manner that the physical characteristics of the metal will be greatly improved by the rolling.

Other objects of the invention and the features of novelty will be apparent from the following description taken in connection with the accompanying drawings, of which Figure 1 is a plan view of a machine embodying my invention, certain parts being shown in section;

Fig. 10 is a section on the line 1010 of Fig. 1.

Referring to the drawings, and more especially to Figs. 1 and 2, the machine comprises a feeding mechanism A, a rolling ma- 5e chine B, a press 0 for cutting the rods or bars to lengths, and a table D on which the rods are delivered.

In general, the operation of the machine consists in passing a rod or bar, of indefinite length, through the feeding mechanism A, the rolling machine B and the cut-oft mechanism C in succession and as a continuous operation without stopping. The feeding mechanism A is adapted to force the rod through the rolling machine B, and the latter reduces the rod to the desired diameter and delivers it to the cut-off mechanism C in finished form where it is cut to lengths, and the lengths are delivered onto the table Extending along the back of the machine, and supported in suitable bearings, 1s a shaft 20 which is driven from a motor 21, or other suitable source of power, by any suitable form of drive, such as the multiple belt drive indicated at 22. The feeding mechanism consistsv of a suitable frame 23, in which there are arranged shafts 24 which carry on their outer ends grooved rolls 25, arranged in pairs to engage with the upper and lower side of the rod so as to force it into and through the rolling machine B. The

feeding mechanism just described is of a typewell known in the art and the details of co nstruction may be varied within wide limits as they form no part of the present inventlon. The feeding machine may be driven from the shaft 20 by gearing such as indicated at26, for purpose of illustration. In accordance with the usual practice, the pressure of the rolls 25 on the rod may be varied by means of suitable adjusting screws 27.

As a matter of efiicient design, the feeding mechanism A and the rolling machine B may be mounted on a base consisting of I-beams 28. The rolling machine comprises two housings 29 and 30 which are spaced apart longitudinally of the machine and connected by the rods 30. The housings 29 and 30 are suitably bolted to the I-beams 28 and each housing carries, at its lower corners, rollers 31 which are mounted for rotation on shafts 32. At the upper end of each of the housings 29 and 30, there are ways 33 on which the box 34 is vertically slidable. Each of the boxes 34 carries a shaft 35 on which a roller 36 is rotatably mounted, the rollers 36 being similar to the rollers 31 and the rollers carried by each housing constitute a seat, arranged in triangular formation, to support the opposite ends of a barrel or drum 37. The boxes 34 are vertically adjustable and secured in any desired position by means of the bolts 38 '42 on the interior thereof and the bottom surfaces 43, of these ways, are inclined with re spect to the axis of the drum, as shown in Fig. 3. A bearing member 44 is arranged in each of the ways 42 and these bearing members are adjustable axially of the drum 37 and are clamped in any position, to which they are adjusted by bolts 45 which are threaded into the bearing members and pass through slots 46 in the drum.

Each of the three bearing members 44 carries a roll 47 in boxes 48 which, as shown in Fig. 5, encircle more than one-half of the ci7rcumference of the journals 49, of the rolls Each of the bearing members 44 has an extension 50. at one end, which carries a thrust bearing 51 for taking the end thrust in the rolls 47. Each of the rolls 47 is also provided with ,gear teeth 52, which are of sufficient length to operatively mesh with idler gears 52, for all adjustments of the rolls 47 axially of the machine. The idler gears 52 mesh )vvith an internal gear 53 which is .ccured in a drum 54 having a hub 55 that is rotatably supported in a bearing in the hub 56-on a plate 57 that is secured to the end of the drum 37 by means of the bolt 58.

Referring to Fig. 3, it will be noted that each of the rolls 47 has a tapered portion 59.

adjoining the rolling surface of the roll, at

the .end of the latter which receives the rod from the feeding mechanism A. This tapered portion is for the purpose of facilitat,

. ing the entrance of the rod between the rolls 47 by gradually reducing the'diameter of the rod as it enters between the rolls.

In order to adjust the opening between the rolls 47 or, in other words, to adjust the size or diameter of the finished rod, T provide means for s multaneously moving the three rolls 47 radially and longitudinally of the rod, the inclination. of the surfaces 43, to the axis of the machine, providing for the radial adjustment. There is secured to the bearing members 44 a plate 60. This plate 60 is provided with radial slots 61 for the bolts 62, the latter being threaded into the ends of the bearing members 44 and securbeing understood that the bolts 62 will be loosened for such adjustment and then tightened when the adjustment has been made. It will also be understood that the'bolts 45 are loosened in order to make an adjustment of the bearing members 44.

A collar 63 is secured to the plate 60 by the cap screws 64 and is provided with a recess to receive the head 65 of the screw 66, the head 65 being rotatably confined by means of the collar 63. The screw 66 has a threaded engagement with the hub of a plate 67 that is secured to the end of the drum 37 by means of bolts 68. The outer end of the screw 66 has its sides flattened, as indicated at 69, to receive a wrench for the purpose of turning the screw in making adjustments of the hearing members 44. A. look nut 70 is arranged on the outer end of the screw 66 for the purpose of securing it in any position to which it is adjusted.

There is a central opening through the screw 66 to permit the rod to pass from the feeding mechanism A to the rolls 47 and, it will be noted, a suitable guide '71 is provided on the outer end of the screw, and there is also an opening 72 in the plate 60. The hub 55, of the drum 54, is also bored out to receive the guide bushing 73 through which the rolls 47 through the idler gears 52 and the gear teeth 52 which constitute pinions on the ends of the rolls 47.

The idler gears 52 are mounted on stub shafts 76 which are secured to the drum 37, between the ways 42, as shown in Fig. 4, and it will be noted that the teeth 52 of-each of the rolls 47 mesh with its idlergears 52 -at a point which permits radial adjustment of the rolls 47 without materially affecting the correctness of the meshing of the teeth for the difierent radial adjustments of the rolls In the operatidn of the rolling mill the rolls 47 tend to rotate the rod, which is being rolled, in one direction and at a speed dependent upon the speed of the rolls and the relation of the diameter of the finished rod to the diameter of the working faces of the rolls and, in order to counteract this tendency to rotate the rod, the drum 37 is rotated in the opposite direction at the same speed of rotation that the rolls tend to rotate the rod, these speeds being accurately synchronized by the variable speed mechanism 78.

The working faces of the rolls 47 are relatively long so that the rod, in passing through the mill, will be accurately sized and given a smooth, rolled finish. The rod, when thus finished; passes through the guide tube 73 to the cut-off machine C.

The machine C consists of a suitable press,

9 such as apunch press, which may be driven from the shaft by means of a pulley 81 and belt 82. The plunger 83 of the press has secured therein, in the usual manner, the head 84 which cooperates with the die member 84' that is slidable thereunder and carries the shear blade 85 that cooperates with the edge 86 of the plate 87, to shear offthe rod, which is received through the guide tube 88 that is mounted in the plate 87. The member 84' 5 together with the blade 85 is continuously urged to its upper position by the springs 88. The member 84' and the plate87 are held in proper alignment at all times by the posts 89.

The bed 90 of the press is provided with 5 ways 91 in which the plate 87 is adapted to slide, back and forth, longitudinally of the rod that is being rolled. Mounted on the plate 87 is a rack 92 with which a pinion 93 meshes. The pinion 93 is keyed to a shaft 0 94 that is rotatably mount-ed in a bearing bracket 95 on the bed 90. The shaft 94 also carries a bevel gear 96, which is keyed thereto and with which two bevel pinions 97 and 98 are constantlyin mesh. The gear 96 and 5 the pinions 97 and 98 are arranged in a housing 99 which forms an extension of the bracket 95. I

The pinions 97 and 98 are keyed to sleeves 100 and 101, respectively, and these sleeves 0 are loosely mounted for rotation on a shaft 102 which is supported in the bearings 103, in the housing 99, and driven by any suitable means from the shaft 20 or other source of power. The sleeve 100 is provided with 5 clutch teeth 104 and the sleeve 101 is provided with clutch teeth 105. A sliding sleeve 106 is splined on the. shaft 102 and has clutch teeth at its opposite ends to engage with the teeth 104 or 105.

0 The sleeve 106 is engaged by a yoke 107 that is loose on a longitudinally shiftable shaft 108,'this shaft being mounted in bearings 109 in the housing 99. Collars 110 and 111 are secured to the shaft 108, on opposite sides of 5 the yoke 107 and coil' springs 112 and 113 107 to the left.

are arranged on the shaft 108 between the collars 110 and 111 and the yoke 107.

An arm 114 is bolted to one end of the member 84' and carries a set screw 115, which is adjustable therein and in alignment with the shaft 108. Bolted to the opposite end of the member 84' is an arm 116 having a set screw 117 adjustable therein and in alignment with the opposite end of the shaft 108.

A detent 118, in the form of a bell-crank lever, is pivoted at 119 to the housing 99 and has its upper end pivotally connected with a rod 120 that is slidable in a bracket 121, on the housing 99. The rod 120 is connected with a lever 121 (see Fig. 1) which is pivotally mounted on the table D. A sliding rod 122 is also connected with the lever 121 and supported in brackets 123 and has its outer end operatively connected with a trip-lever 124 that is pivotally mounted on a bracket 125 on the table D and projects into the path of the rod, being rolled, as the latter is moved along the angle iron 126, forming a part of the table D.

The sleeve 100 is held against longitudinal movement on the shaft 102 by a collar 127,

which is pinned to the shaft 102 and over which the clutch member 106 is adapted to move when shifted into engagement with the teeth 104. In a similar manner the sleeve 101 is held against longitudinal movement of the shaft 102 by a collar 128.

A detent 129 is pivoted to the housing 99, at 130, and has a hook 131 on its outer end, which is adapted to engage the end 132 of the hub of the yoke 107 for the purpose of holding the clutch member 106 in engagement with the teeth 104. A similar detent 133 is pivoted to the housing 99 at" 134 and has a hook 135 that is adapted to engage with the end 136 of the hub of the yoke 107, to hold the clutch member 106 in engagement with the teeth 105.

In the operation of the cut-off mechanism, assuming that the blade 85 is in its upper position to allow the rod to pass through the cut-off die, the advancing rod will move along the angle iron 126 until the end strikes the trip-lever 124. This lever will be moved to the right, in Fig. l, by the advancing rod and the rods 120 and 122 will be moved, thereby, to the left. The normal positions of the detents 118, 129 and 133 are shown in Fig. 7 and the spring 113 is compressed and the spring 112 is free. The movement of the rod 120 to the left, raises the detent 118 out of engagement with the hub of the yoke 107 and permits the spring 113 to shift the yoke This movement of the yoke 107 causes the clutch member 106 to engage with the teeth 104. Since the shaft'102 is constantly driven, the engagement of the clutch member 106 with the teeth 104 will cause the bevel pinion 97 to be rotated by the shaft 102 and, in turn, rotate the bevelgear 96. Since the gear 96 is keyed to the shaft 94 and the gear 93 is also keyed to the shaft, the gear 93 Will be rotated and move the rack 92 and the slide plate 87 in the direction of movement of the rolled rod. The speed of the shaft 102 is properly timed to cause the slide plate 87 to move at exactly the same speed as the rolled rod until the usual trip mechanism for the press C isactuated by the cable 123", which is attached to the rod 122 and causes the plunger of the press to descend so that the blade 85 will cut the rod in two. The cut-off section of rod is then pushed on until it is free from the cutoff mechanism and then rolls down the inclined table 137. A spring 138 restores the tri -lever 124 to its original position.

When the yoke 107 is initially shifted to the left, in Fig. 7, by the spring 113, as above described, the hook 131, on the detent 129, will drop into engagement with the end face 132 of the hub of the yoke and hold the clutch member 106 in engagement with the teeth 104. As the cut-off die moves alongwith the rolled rod to the position where the cut-off is made, the arms 114 and 116 will also be moved along with the cut-off die because they are mounted thereon. The end of the set screw 115 will, therefore, engage with the end of the shaft 108 and cause the latter to be moved to the right, in Fig. 7, with the cut-off die. When the clutch member 106 is shifted into engagement with the teeth 104, the yoke 107 moves to the left, in Fig. 7, about one-half of the distance between the end face 136 of the hub of the yoke, and the end of the spring 112. As the shaft 108 continues to move toward the right, the spring 112 will engage with the end surface 136 and, since the collar 110 is pinned to the shaft 108, further movement of- .the shaft 108 will cause the spring 112 to be compressed. It will be noted that the yoke 107, during this movement of the shaft 108,

has been held in a stationary position by the detent 129 but when the cam surface 139, on the collar 110, engages with the cam surface 140, on the detent 129, the latter will be lifted and the hook 131 will be disengaged from the end surface 132, thereby permitting the compressed spring 112 to shift the clutch member 106 to the right and into engagement with the teeth 105.

The engagement of the clutch member 106 with the teeth will cause a reversal of the rotation of the gear 93 and the cut-off die will then be moved to the left, in Fig. 6. When the clutch member 106 is thus shifted to the right, in Fig. 7 the detent 133 will be permitted to drop and the hook 135 will engage the end surface 136 of the hub of the yoke and thus hold the clutch member 106 in engagement with the teeth 105 until thecutoff die is returned to its original position, shown in Figs. 6 and 7. The movement of the cut-off die to the left, in Fig: 6, causes the end of the screw 117 to engage the end of the shaft 108 and when the cut-off die reaches its neutral position the shaft 108 will be in the position. shown in Fig. 6. Just before the cut-off die reaches its neutral position, the cam surface 141 on the collar 111, will engage with the cam surface 142 on the detent 133 and lift the latter out of engagement with the hub of the yoke 107 and permit the spring 113, which has been compressed by the movement of the shaft 108 to the left, to shift the yoke 107 to its neutral position in engagement with the detent 118. This movement of the yoke 107 disengages the clutch member 106 from the teeth 105 and restores the clutch member 106 to its neutral position, shownin Fig. 7, and in this position the cut-off die is stationary and will remain so until the advancing rod again engages with the lever 124 which will start another cycle of the operations of the cut-off mechanism.

From the foregoing description, it will be apparent that the feeding mechanism A will force the rod, to be rolled, through the rolling machine B where the rolls 47 will reduce the rod to the desired finished size and the cut-off mechanism C will cause the rod to be automatically cut into predetermined lengths which are determined by the position to which the lever 124 is set, it being understood that the bracket 143, which carries the lever 124, is adjustable along the angle iron guide.126 and that the connection 144, between the lever 124 and the rod 122, will be adjustable along the latter.

While I have illustrated and described what I now consider to be the preferred embodiment of my invention, it will be understood that various changes may be made in the details of construction without departing from the spirit of the invention as defined in the appended claims.
