MOTION PICTURE REEL.

APPLICATION FILED 0CT.1T, 19 19. RENEWED AUG. 1, 1922.

ELLIOTT B. CLARK, F WELDON, NORTH CAROLINA.

MOTION-PICTURE REEL.

Application filed October 17, 1919, Serial No. 331,283. Renewed August 7, 1.922. Serial No. 580,278.

To all whom, it 1n my concern:

Be it known that I, ELLIOTT CLARK, a

V citizen of the United States, residing at Weldon, in the county of Halifax and State of North Carolina, have invented certain new and useful Improvements in a Moton-Picture Reel, of which the following is a specification.

his invention has relation to certain new and useful improvements in film reels, the

object of my invention being to provide an improved. iihmwinding reel which is interchangeable with an ordinary film-feeding reel, and to connect the winding reel to the feeding reel through the medium of suitable gearing to cause these reels to rotate at the same speed, thereby eliminating the services of one man now necessary to rewind the film.

1th these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification and in which like numerals of reference indicate similar parts in the several views:

Figure 1 shows a side view with parts broken away, of a reel embodying my invention, positioned and arranged for use as a feed reel or payingbut reel.

Figure 2 is an edge view partly in vertical section.

Figure is a detail of the film clamp,

Figure t shows the clamp in position.

As shown in the drawings I employ a casing comprising a back plate 10, from which extends the tubular hub 11, this hub having: the access slot .12.

Revolubly surrounding this hub 11 is the reel proper comprising the outer plate 9, having the radially disposed slots 4), and fixed to this plate 9 is the belt pulley 8 receiving the belt '3", by means of which the pulley is rotated. The belt 7 is driven by any appropriate means (not shown) and connects this pulley 8 with another pulley 8 (not shown), of the same diameter, of an ordinary paying-out reel or one of the kind of reels here shown; these similar reels being used alternately and interchangeably as feed-reels and winding-reels.

Communicating with the hub 11, is the chute 13, this chute being laterally offset as shown, the intake end of the chute being opposite the slot w in the drum or hub 11.

Situated opposite the intake end of the chute 1.3 are the rolls 6, 6, while located adjacent to the slot 02 are the rolls 5, 5, these rolls guiding the film into the chute laterallylas shown in Figure 2.

eld to the reel is the film holder 15 comprising a slotted member which is tightened by means of the wing nut 4 on the threaded end 3 of the holder 15.

Each. of the slots 0: is adapted to receive a similar one of the holders 15, but only one of such holders is here shown, the others being removed and not shown. These film holders are radially adjustable in the slots '0, to compensate for films of different lengths (viz film-coils of different inner and outer diameters). The reel-holders are also shiftable from the outer periphery of the coil to its inner periphery, so that when the film has been fully wound onto the reel, around the holders 15, these holders can then be shifted to the exterior of the coil, and one of the holders caused to clamp the outer end of the coil, (as shown. in Fig. 1), and then the two interchangeable reels are reversed as to their respective functions; that is, the empty one is used as the winding reel, and the full one is used as the feed-reel, the film being fed from the center of reel and interior of coil, through the chute 13, and the empty reel takes up the unwound part of the film and winds it in the outer sides of the holders 15. Each pic ture show could have a stock of these reels and wind from reel now in use on to this reel and thence to a similar reel and show as many times"""as wanted, then rewind on original reel at his leisure-atter the show was over. This would do away with the use of one man, and consequently cut down ex enses.

While the illustration and description. of this invention is confined to a certain degree of particularity it is to be realized that in practice various alterations and changes may be made, and therefore the right and privilege of changing the form of the details of construction and otherwise altering the arrangement of the correlated parts is reserved without departing from the spirit of the invention or the scope of of the coil, or to be wound thereon in suethe appended claims. cessive outer convolutions.
