Janda and need not be shown nor described here in greater detail. Sufiice it to state that shaft I5 is driven from the motor and suitable control means is provided for effecting movement of the shoe as desired.

Shaft I5 is disposed coaxially with an upper shaft section i5 and has secured thereon, above the sembly l8, a clutch member 35. Shaft section [5* is rotatably mounted through a thickened element or rib, 36 of housing II and has appropriately mounted thereon, for sliding movement, a clutch member 31 which cooperates with clutch member 35. An arm 38 is loosely mounted on shoe shaft 22 and has lost motion connection 39 to arm 2|. At its forward end arm 39 is appropriately connected to clutch member 31 for raising and lowering the latter, in accordance with rearward and forward movements of shoe 28. A control plate 40 is slidably mounted on rib 36, by pin and slot means 4|, this plate being provided with a suitably formed opening 42 receiving a pin 43 connected to the forward end of arm 38. Plate 40 is adjusted by means of a rod 44 connected thereto and slidable through the front wall of housing II, the forward end of this rod having a suitably shaped head or button 45 approximately secured thereon. In the normal position of plate 40, shown in Figure '2, clutch member 31 is moved into and out of operative position, in accordance with the movements of the shoe shaft 22. By moving plate 40 into its outer or forward position, clutch member 31 is held in its raised or inoperative position, when the shoe 28 is moved to its forward position. The construction and operation of the parts just referred to are fully disclosed in the patent to Rudolph W. Janda, above identified, and need not I be further illustrated nor described here.

A bevel pinion 41 is secured upon the upper end of shaft section l5, above rib 36, and meshes with a bevel gear 48 secured upon the outer end of a roll shaft 49. The latter shaft is rotatably mounted through a boss 59 projecting inward of gear housing II, from the inner end wall of the latter, A boss 5| projects from the outer face of the inner end wall of housing II and has extending therefrom an integral tubular hub 52, this hub and boss 5| receiving the inner end portion of a tubular member or sleeve 53, secured in hub 52 and boss 5| in any appropriate manner.

Shaft 49 extends outwardly beyond the other end of sleeve 53, the latter being provided at said other end with a bushing 54 rotatably supporting shaft 49. A washer 55 is disposed about shaft 49 and is confined between the inner end of sleeve 53 and a trust collar 55 pinned or ter shaft, which is the roll drive shaft. is thus "rotatably mounted in the supporting structure,

comprising gear housing II and sleeve 53, and this shaft is driven by the motor when clutch member 31 is in its lowered or operative position.

A roll 56 is mounted concentrically with shaft 49 and sleeve 53 for rotation and for lengthwise reciprocating movement. This roll comprises a sheet metal cylinder 51 provided with, a suitable pad 58. A spider 59 is suitably secured, as by riveting, within cylinder 51 a short distance inward beyond thrust collar 55'. Spider i9 is provided with a hub 66 having a,squared bore 6| which slidably receives squared and reduced portion 49a of shaft 49, proiecting beyond thrust 60a appropriately slotted for reception of two pairs of rollers 62 mounted to turn freely upon pins 53 appropriately secured in portion 60a of hub 60. The rollers of each pair contact the opposite flat faces of squared portion 49a of shaft 49, as will be clear from Figures 3 and '7. Roll .56 is provided, adjacent its other end, with a spider 64 riveted to cylinder 51, which spider is provided with a hub 65, rotatably and slidably mounted upon sleeve 53 by means of a bushing 66. Roll 56 is thus mounted upon sleeve 53 for rotation about the latter and for reciprocation lengthwise thereof.

Spider 64 is provided with an integral finger 61, at its periphery, extending lengthwise of cylinder 51 toward the adjacent end thereof. Finger 61 is provided, at its outer end, with a col- ,lar 66 projecting inward of roller 56 radially thereof. A headed and shouldered pin 69 is secured in collar 68 and carries, at its inner end, a roller 10. Roller 10 engages within a cam groove H of a cam member 12 mounted upon boss 5|. Groove 1i is of undulatory formation, as will be clear from Figure 5. Normally, cam member 12 is fixed to boss 5|, with roller 10 engaging in groove 1| and cooperating with the walls thereof for reciprocating roll 56 lengthwise,

during rotation thereof. The spider 59 and as-- rectangular slot 14 which receives a rectangular enlargement 52* of hub 52, at the outer end of the latter. Each web element 13 is provided with a lengthwise slot 15 which receives a fiat headed screw 16 threaded into boss 5!. Cam member 12 is further provided, at the front thereof, with an outwardly projecting lug 11 which fits into a corresponding notch 18 in boss 5|. A screw 19, provided with a socketed head, passes through lug 11 and threads into boss 5|, lug 1.1 being appropriately recessed for reception of the head of screw 19. Web elements 13 fit snugly about enlargement 52 and cooperate therewith for holding the cam member 12 against turning movement. When screw 19 is turned tightly into boss 5|, cam member 12 is locked against movement transversely of hub 52 and effectively anchored to boss 5|, the heads of screws 16 bearing against the inner faces of segments 13, as shown in Figure 3.

In order to place the roll 55 upon the machine, screw 19 is threaded out of boss 5| and the cam member is slid toward the front of the machine to the extent limited by enlargement 52 of hub 53, it being noted (Figure 4) that the rearward portion of enlargement 52 is shaped conformably to the corresponding end of slot 14 and is spaced a considerable distance therefrom. This permits forward movement of cam 12 to such an extent that, when the roll 56 is turned into position such that pin 69 is coaxial with screw 19, pin 69 and roller 10 carried thereby will clear cam member 12, thus permitting the roll 56 to be moved lengthwiseaway from gear housward into such position that the roller Ill en-.

gages in groove I2, in which position it is secured by means of screw 19, as previously described. The roll 56 maythus be removed and replaced with expedition and facility, as conditions may require, the means for reciprocating the roll also serving to retain it in position upon the supporting structure.

In the modified form shown in Figure 6, a cam member fits about an enlargement 52 at the outer end of hub 52 and is secured to boss 5| by cap screws 8|. The cam member I2 of Figure 3 is a box cam, whereas the cam member of Figure 6 is an open cam provided at its inner side with an undulatory cam track, as will be clear from Figure 6, amino adjustment thereof is necessary for mounting or demounting of the roll 55. Roll shaft 49 is provided with a squared portion 49 'extending through hub 60 of spider 69, and with a cylindrical threaded portion 49 extending from squared portion 49. A compression coil spring 82 is confined between hub 90 of spider 59, about the end portion of shaft 49, and a washer 93 disposed about portion 49 of shaft 49 and abutting a nut 84. threaded upon the shaft. Spring 92 maintains roller 10 in contact with the undulatory track of cam member 80, which cooperates with roller 'lli'and associated parts for reciprocating roll 56 lengthwise, during rotation thereof. By removing nut 94 the roll 56 may be removed and replaced with expedition and facility, as required.

In both forms .of my invention illustrated, the roll of the machine is reciprocated lengthwise during rotation thereof. The extent of reciprocation need not be great, approximately one-quarter of an inch sufllcing in most cases. In Figure 1 the roll is shown at the limit of its movement toward the right, as indicated by the arrow al, in which position the ends of the roll are flush with the ends of the shoe 29. After reaching the position shown in Figure 1 the roll, in its continued rotation, is moved in the opposite direction, indicated by the arrow a2, so as to extend beyond the left hand end of shoe 29, as viewed in Figure 1, a short distance, approximately one-quarter of an inch. In both forms of my invention illustrated by way of example, the roll is rotated by power derived from the motor I8 and is also reciprocated by power derived from the same source, this motor also furnishing the power for moving the shoe to and from the roll.

While I have illustrated two preferred forms of my invention, by way of example, changes in construction and arrangement thereof may be resorted to without departing from the field and scope of the same, and I intend to include all such variations, as fallwithin the scope of the appended claims, in this application in which the preferred forms only of my invention have been disclosed.
