To all whomz't may concern:

Be it known that L'WILLIAM HEINZE, a citizen of the United States, residing at Darby, in the county of Delaware and State of Pennsylvania, have invented certainv new and useful Improvements in Film-Reeling- Devices, of which the following is a specification. v

This invention relates to reeling devices, and particularly to mechanism for windingor reeling the film employed in connection with moving picture apparatus.

The primary object of theinvention is to provide means whereby the re-winding of picture film after the same has been. run through the projecting apparatusfmay be accomplished simultaneously with the opera tionof the picture projecting mechanism.

A further object of theinventionis to provide means whereby the energy employed in operating the picture projecting apparatus may be utilized to re-wind the film which may have been previously displayed.

A still further object of the invention is to, provide'simple and eificientmeans for ob-- viating the necessity of resorting to the additional function of re-winding picture film after it has been displayed before another filnr can be shown.

A still further and particular object of the invention is to provide a mechanism capable of application toany of the standard: types of picture projecting apparatus, which is simple and inexpensive in construction, which is composed of but few simple and readily assembled parts, which parts are so arranged as to-prevent the least possibility of the same becoming: broken, worn, or deranged during operation, and which will prove thoroughly practical and efiicient for the purposes towhich it is adapted.

lVith these objects in view, together with others which will appear as the description proceeds, the invention residesin the novel. combination and arrangement ofparts, all as will be described more fullyhereinafter, illustrated in the drawings and particularly, pointed out in the claims. I 1

The invention will be best understood by reference to the accompanying drawings, wherein- Figure-1 is a side elevation of a film reeling device constructed. in accordancewith myinvention,Fig. 2 is aver-tical transversesection taken. through the; device,Fig. 3 is a fragmentary vertical section. taken, through the casing for the device and. illustrating the association of the film reels,-Fig, 4 is a sectionalv view taken 01111118 4.-4 of Fig. 1,- and Fig. 5- is an enlarged fragmentary sectional view taken upon line 55. of Fig. 4.. 7

As is well known to those more intimately associated with. the art of exhibiting film to produce animated pictures, it is necessary after displaying each reel of film tore-windthe same, in order that it may be reeled properly for further display. Qrdinarily, for this purposaseparate machines or reel.-

ing devices are employed, although in some apparatus the film is reversed through the 1 pro ecting mechanism, and the re-winding of the picture strip or film by these methods not only devolves additional laborupon the machine operator, but in someinstancesdelays the performance to the annoyance and discomfiture of the audience. Again, the haste resorted to by the machine operators by these methods in quickly re-winding the film, often results inbreaking or tearing the picture strip. The present invention aims to overcome these objections.

In carrying out the invention, the shaft commonly usedin projecting; apparatus for the accommodation of the empty spoolv or reel upon whichthe film is: wound during the pictureprojecting operation, is arranged to loosely hold a reel which may be filled with, picture strip which. has-.been-preuiously exhibited, and a second shaft is arranged in near proximity to the first named shaft tobe' driven; thereby, and tocontainan empty spool or reel for the reception of the picture strip. contained upon the filled: spoolupon the first mentioned shaft. If desired, the

two shafts may be so'intergeared that the second shaft will rotate; more rapidly than the first shaft, to insure a complete re-winding ofthe film upon the filled spool regardless of the abbreviated length of therpicture:

strip, being exhibited.

loo

More particularly, a casing 6 of suitable size, construction and shapeis arranged for the support. of a shaft: 7, which shaft is adapted to support and impart rotary movement to the film receiving spool or reel; 8.; the film being'led to the spool 8' after it has been exhibited through the opening:- 9 in. alinementi therewith. A. suitable bracket 10 may, bev secured upon the exterior. of the casing. 6 rforithe. accommodation and, support of theshaft 7 a bushing: 11. being; arranged within the; bracket 10,1and. the outer ex? tremity of the shaft 7 has secured thereto a double pulley 12, having small and large

belt receiving portions

13 and 14 respectively. The portion of the shaft 7 which extends within the casing is preferably of such diameter as to receive the standard picture reels or spools, and a collar 15 may be secured to the shaft 7 by means of a screw 16, at the juncture of the smaller with the larger portion of the shaft; a key 17 being arranged upon the collar to extend a short distance longitudinally of the shaft for engagement within. the key way 18 common to the usual moving picture reel. From this construction it is apparent that when the reel 8 is inserted upon the reduced portion of the shaft 7 with its key way engaged by the key 17, and the shaft rotated, the spool 8 will operate to receive and Wind the picture strip delivered from the picture projecting mechanism. It is apparent also that when desired the reel 8 may be readilyv withdrawn from the shaft.

The reduced portion of the shaft 7 is of such length as to extend practically the entire width of the casing 6, and a bearing block 19 is arranged upon the door 20 adjacent the free end of the said shaft, the said block being provided with a suitable bore 21 for the accommodation and support of the free end of the shaft 7 when the door is in closed position. The bearing block 19 is supported between a pair of brackets 22, set-screws 23 being threaded through the said brackets and in engagement at their ends with the block 19, the arrangement providing means whereby the said block may be adjusted to properly aline the same with the end of the shaft 7. The door 20 is of such size preferably as to cover the entire side of the casing, so that when swung to open position upon its hinges 2A the entire interior of the casing will be easy of access.

The spool or reel which is adapted to be rewound by the use of the device, is indicated at 25, and is adapted, to be positioned upon the shaft 7 next to the reel 8 so as to rotate thereon. A spring clip 26 may be secured as at 27 to the end of the bearing block 19 to engage and exert slight pressure upon the side of the reel 25 to prevent movement of the latter longitudinally of the shaft, and to hold the reel 25 snugly against the reel 8. Suitable spacing members or washers 28 may be inserted between the reels, between the collar 15 and the reel 8, and between the spring member 26 and the reel 25.

A second shaft 29 is mounted similar in manner to the shaft 7 adjacent the lower part of the casing and parallel with the said upper shaft. A suitable bearing block 30 is secured upon the interior of the casing 6 for the support of the shaft 29, the said block having its bore provided with a bushing 31 projecting beyond the casing to engage the inner face of a belt pulley 32 secured upon said shaft in alinement with the enlarged portion 14 of the member 12 upon the shaft 7. The opposite end of the shaft 29 projects beyond the inner extremity of the block 30, and is provided with a key 33 for engagement within the standard key way upon the picture reels. The arrangement is such that when a spool or reel 3 is inserted upon the inner end of the shaft 29, and the cap 35 applied to the shaft end, the spool or reel 3 1 will be in alinement with to receive picture strip or film from the spool or reel 25 mounted for rotation upon the shaft 7. A belt 36 may be passed over the portion 1st of the member 12, and over the belt pulley 32 upon the shaft 29 for the purpose of imparting power from the first to the second shafts, and if desired this belt may be crossed to drive the second shaft in a direction reverse from that of the first. It is also found desirable to have the belt pulley 32 smaller in diameter than the portion 14, in order that the shaft 29 may rotate more rapidly than theshaft 7. Power is imparted to the shaft 7 by means of a belt 37 driven by suitable mechanism upon the projecting machine, the said belt passing over the portion 13 of the member 12.

In operation, an empty picture film reel or spool 8, is inserted upon the shaft 7 with its key way engaged by the key 17, and the end of the picture film to be exhibited is secured to the said reel. A reel of film which it is desired to rewind, is inserted upon the shaft 7 and is free to rotate thereon. The end of the film contained upon the filled reel is connected to the emty reel 34 secured to rotate with the shaft 29, and the cap 35 is secured over the end of the shaft 29 to prevent the reel becoming disengaged therefrom. The door 20 is then closed, and the bearing block 19 receives the free end of the shaft 7 within its bore. The spring element 26 upon closing of the door engages the reel containing the film to be re-wound and holds the same against lateral. or wabbling movement upon the shaft 7. Upon operation of the picture projecting apparatus, rotary movement will be imparted through the belt 37 to the shaft 7, whereupon the film being exhibited will be wound upon the reel 8. Rotary movement is transmitted from the shaft 7 to the shaft 29 by means of the belt 36, and the film contained upon the reel 25 will be wound upon the reel 34 carried by the latter shaft. By reason of the more rapid rotation of the shaft 29, the film upon the reel 25 will be completely transferred in correct display position to the reel 34 before the receiving reel 8 is filled. The spring element 26 by its engagement with the loose reel 25 acts as a brake for the latter to prevent racing of the same during the operation of the device. By this arrangement it is obvious that the films may be rewound at the same time that other picture film is being exhibited, and by the construction shown, the various film reels may be quickly and easily removed or transferred from one shaft to the other.

While in the present instance I have illustrated and described my invention in what appears to me to be its most practical form, I am aware that the construction set forth is susceptible of various minor changes in form and details, and I reserve to myself the right to make such changes as I may deem practicable or desirable without departing from the spirit of the invention.
