ing 01 from a driver pulley 66.

After leaving the circular guide 46, the strip is finally drawn down around the rewind roll 53 which is supported on a center 5! extending from a large flat disk 52, which is frictionally driven by mechanism, the speed of which is regulated according to the diameter of the rewind roll. This fiat disk 52 is pivoted on a frame 53 which extends from the main frames of the machine and is supported on a shaft 54 centered in the two main side frames. A bracket 55 is braced between the outer end of frame 53 and the side of base 2| to act as a support for the rewind mechanism.

The main driving connections are established by means of belts and pulleys and their general location can be noted on Fig. 1. There it is seen that the shaft of motor M carries a pulley 50 which acts as a drive for a belt 6i which is wound around a larger pulley 52 connected directly to the main drive gearing of the printing mechanism. Also connected to pulley 62 is a small pulley 53 for operating a belt 64 cooperating with a large pulley 65 mounted on the shaft 54 already mentioned as the rewind driving shaft.

This shaft carries a small pulley 66 for supporting a belt 61 which is twisted to cooperate with a small pulley 68 swung out on an arm 59 and mounted on a movable vertical center in connection with a friction driving wheel 295 for rotating the rewind disk 52.

Regarding the rewind operation, it is already explained with reference to Fig. 1 that the rewind roll 50 is located on the shaft 5| extending from a friction disk 52 which is driven by belt- Reference to Fig. 4 shows the parts in a plan view and there the supporting bracket 53 for disk 52 and shaft 5| is seen to be secured to a shaft 54, which runs through th main side frames 22'and 23 and on its two ends carries the pulleys 65 and 66. There it is also noted that the friction driving wheel 295 is carried on a swinging arm or lever 69 also pivoted on shaft 54.

On the end of rocking lever 69 there is pivoted at 28! a rocking frame 288 which carries a U-shaped bar 289 for supporting the friction driving wheel 295. Mounted as an L-shaped extension from rocking frame 288 is a supporting member 290 for carrying a freely turning follower roller 29! which rests' on the periphery of the rewind roll 50 and serves to follow the enlargement of the diameter of this roller and thereby swing the operating point of the friction drive out toward the enlarged diameter of the friction disk 52, so the rewind action is constantly proportional to the size of the rewind roll.

In Figs. 2 and 3 the rewind driving parts are shown in greater detail and in the sectional view (Fig. 3) it is seen that a number of parts are confined between the extending ends of the U-shaped hanger 289. Near the top of the hanger is the driving pulley 68 containing a ball bearing 292 for permitting it to rotate freely on a vertical shaft 293 passing through openings in both ends of the arms on the hanger. Th pulley 68 is seen to be formed with a cylindrical extension 294 upon which is fastened the friction driving wheel 295 as a conical ring of rubber or other frictional material shaped to cooperate with the side wall of the friction disk 52. Insid the lower end of cylinder 294 is another ball bearing 296 encircling the shaft 293 and insuring free rotation of the connected part on this shaft.

Shaft 293 also carries a means for throwing off the friction driving connections so that the rewind may be disabled at any time. These throw-off connections are pinned to opposite ends of shaft 293. At the upper end of the shaft is fastened an extending arm 29'! (Fig. 2) cooperating with a stop pin 298 which extends from the top of hanger 289 for limiting the rocking movement of the lever. At the lower end of shaft 293 (Fig. 3) is fastened another arm 309 carrying a roller 30! normally out of contact with the face of disk 52. However, when arm 29'! (Fig. 2) is rocked counterclockwise for the throwing-01f operation, arm 380 is moved in the same direction and roller 30! presses against the side of the friction disk 52 and shaft 293 is shoved away from the disk so that the friction driving wheel 295 is moved out of cooperation with the disk. When the parts are so situated, the pulley 68 and friction driving wheel 295 are allowed to operate without communicating any driving action to the rewind roll.

A plan view of Fig. 2 shows the details of the connection between the swinging frame 288 and the holder 290 for the follower roller 29!. The connection involves a hinged construction 303 where the end of frame 288 fits into a recess'cut in the side of the member 290. There is a certain amount of play in the joint allowing the roller to move back and forth in following the periphery of the rewind roll. To hold the parts together the end of frame 288 is formed with a T-shaped recess in which fits the head 304 of a bolt which is tightened on the outside of member 290.

In order to uphold the swinging arm 69 and the rewind drive parts thereon (Fig. 4), a spring 305 is attached to a stud 306 extending from frame 23, and at its opposite end is connected to a rod 301 which is fixed to a bracket 308 extending horizontally from the carrying arm 69. Reference to Fig. 1 shows that the link 30Tis shaped to encircle the operating shaft 54. The spring not only tends to swing the rewind parts against the side of friction disk 52, but it also tends to hold the end of the lever 69 down so that roller 29! is maintained in contact with the top of the rewind roll.

A compensating means is provided for swinging frame 288 so that it follows more closely to a radial line of movement across the surface of disk 52 rather than in arcuate path of travel, which would prevail if the holder 288 were fixed to theend of arm 69. Seeing that the parts are pivoted at 287, it is possible to rock the frame 288 toward the right (Fig. 1) as it is elevated and thus flatten out the arcuate path oftravel. For this purpose a link 3l0 is articulated at 311 on the bottom end of frame 288 and the opposite end of the link is pivoted at 3 l 2 on the stationary supporting frame 53.

While there have been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention. It is the intention therefore to be limited only as indicated by the scope of the following claims.

What is claimed is: i

1. In a machine for feeding record material, a main operating means, means for drawing said material off a supply roll, means for supporting a rewind roll, a friction disc associated with said supporting means for rewind connection, a pivoted arm, means on said arm for re ulating the frictional rewind, the last mentioned means including a follower roller resting on said rewind roll and a friction driving wheel mounted therewith and cooperating with said disc for rotating the rewind roll, means under control of said main operating means for rotating said friction driving wheel, a pivoted frame on the end of said arm for holding said follower roller and said friction driving wheel, a link connected at one end to said pivoted frame for rockin it as said arm swings the frame as the rewind roller increases in size, and a fixed pivot for the other end of said link, whereby the path of said friction driving wheel follows a line more radial than arcuate across the face of said disc.

2. A machine of the kind set forth in claim 1 wherein said means under control of the main operating means for rotating the friction driving whee1 includes a. pulley attached to the friction driving wheel, and belting connections from said pulley to a drive pulley operated by the main operating means.

3. In a machine for feeding record material, a main operating means, means for drawing said material off a supply r011, means for supporting a rewind roll, a friction disc associated. with said supportin means for rewind connection, a pivoted arm, means on said arm for regulating the frictional rewind, the last mentioned means including a follower roller resting on said rewind roll and a friction driving wheel mounted therewith and cooperating with said disc for rotating the rewind roll, means under control of said main operating means for rotating said friction driving wheel, a shaft through said friction driving wheel, a manipulative arm on one end of said shaft and a lever with a cam roller on the other end of said shaft for cooperating with the surface of the friction driving disc to cam the friction driving wheel away from the disc when the lever is manipulated to rock the roller against the surface of the disc.
