CHARLES R. UEBELMESSER, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, T AMERICAN STANDARD MOTION PICTURE YORK, N. Y., A CORPORATION OF NEW YORK.

MACHINE COMPANY, INC., OF-NEW WINDING APPARATUS.

Application filed'April 25, 1908, Serial No. 429,135.

To all whom it may concern:

Be it known that I, CHARLEs R. UEBEL- MESSER, a subject of the Emperor of Germany, and a resident of the city, county, and State of New York, United States of America, have invented certain new and useful Improvements in Winding Apparatus, of which the following is a specification.

My inventionrelates to new and useful improvements in winding apparatus and consists in the novel construction and arrangement of parts herein shown and described, the novel features of which are set forth in claims.

Referring to the drawings,-Figure 1 is a side elevation, partly in section, of a portion of a moving picture machine with my invention applied thereto. Fig. 2 is a rear end elevation of the parts shown in F ig.. 1, with a some of them broken away to more clearly show the construction. Fig. 3 is a sectional plan view of the apparatus shown in Fig. 1, the section being taken on the line 33 of the latter figure. Fig. 4 is a plan view of the parts shown in Fig. 1. Fig. 5 is a sectional rear elevation on an enlarged scale of the winding mechanism which I have invented showing some details of its construction. Fig. 6 is'a perspective View of certain parts of my invention illustrating the operation of the apparatus.

L ike characters of reference designate corresponding parts in all of the figures.

10 designates the casing or frame. of a moving picture machine of ordinary con-. struction. I 11, 11 are brackets projecting from the upper portion of this casing and arranged to support a shaft 12 upon which a reel may be mounted. 13 is a sprocketwheel afiixed to' the shaft 12. Projecting from the lower portion of the casing 10 is a supporting frame 14 which supports the vertical spindle 30 and other parts which will be pointed out later.

14 is a bridge-piece extending over the top of the supporting frame 14. One end of this bridge-piece is hinged at 14 and the other end is arranged to be connected with the supporting frame by a spring-catch 14 15 are brackets affixed to the supporting frame which form bearings for a shaft 16, to the outer end of which is affixed a sprocket-wheel 17.

in the form of a short hollow cylinder with a closed base 22. The internal diameter of the vertical flange or wall of this cylinder is preferably about equal to that of the outer diameter of the film upon reel 20. The central portion of this base is carried down through the supporting frame 14 in the form of a hollow circular hub 23. The center of the frame 14 is constructed to form a bearing for this hub, and a washer 24 may be interposed between the base 22 and the upper surface of the frame 14 to allow the receiving member to rotate freely within the frame.

is a bevel-gear affixed tothe hub 23 and in mesh with the bevel-gear 19. The gear 25 is of slightly greater diameter than that of the gear 19. The spindle passes freely through the center of the hub 23 and extends into the center of the receiving member 21. At the upper end of this spindle 30 a driving spool 31 is aflixed. This spool comprises near its upper and lower edges twosets of projecting teeth 32.

33 is an auxiliary guiding spool, the upper and lowerflanges of which bear upon the teeth 32- so that the rotation of spool 31 is transmitted to the spool 33. The vertical support '34, upon which spool 33 is rotatably supported in a slot 14.

mounted, is slidably in the bridge 14%. A spring 35 is provided for pressing the support 34 toward the center of the frame and keeping thefianges of spool 33 in contact with teeth 32 of the drivv 3 ing spool 31.

.36 is a bevelgear aflixed to the lower end of the spindle 30 and in mesh with a similar bevel-gear 37 rigidly mounted upon a shaft 38 which is mounted in the brackets 15 and has affixed to it a sprocket-wheel 39. In Fig. 5 this shaft 38 is shown divided with its two parts connected together through a friction drive connection 38. I

40 is a motor driven shaft upon the upper and lower ends of which are affixed driving gears 41 and 42 which are in mesh with and arranged to drive other gears 43 and 44. The latter gears are arranged to rotate two driving spools 45 and 46, similar in construction to the spool 31, and, like the latter, having auxiliary guiding spools associated with them. 47 is another driving spool arranged to be rotated from the shaft 40 with an intermittent motion through intermediate mechanism which is not shown, as it is a connnon part of a moving picture machine and forms no part of the present invention.

-18 is a sprocket-wheel connected to rotate with the gear 44 and the driving spool 46.

' .A sprocket-chain 49 connects this sprocketwheel 48 with the sprocket-wheel 39.

50 is a film such as is used in a moving picture machine and is provided along its edges with the usual series of perforations 51. The teeth upon all of the driving spools above pointed out are designed and spaced to fit into these perforations and to impart to the film the des red movements.

The various parts of this apparatus have now been pointed out, and I will proceed to describe their operation. The film 50 is wound up and is carried by the reel 20. The latter is then placed upon the shaft 12, to which it is keyed, and the end of the film carried down over the driving spools 45, 47 46 and 31. Now, when the motor driven shaft 40 is rotated, all of these driving spools will be rotated at an equal rate of speed, and the spool 47 will be given the additional intermittent movement before mentioned. This will cause the film to be unwound from the reel 20 at a certain rate of speed, and to be pushed at the same time and at the same rate of speed by the driving spool 31 into the receiving member 21. The internal diameter of the receiving member is made approximately equal to the external diameter of the film 50 when the latter is all wound upon the reel 20. It may be seen that the unwinding of the film from the reel will cause the latter to be rotated. As the film is unwound at a uniform rate, the rate of rotation of the reel will increase as the outside diameter of the film remaining uponthe reel decreases. The mechanical connections between the reel and the receiving member are such that this variable rotation of the reel will be transmitted to the receiving member so that the speed of the latter will increase as the internal diameter of the film, which (s being coiled up within it, gets smaller. In order that this coiling up of the. film within the receiving member be made properly, it is important that the internal circumferential speed of the film within the receiving member be not faster than the lineal speed of the film past the driving spools. In fact it is preferable to make this circumferential speed somewhat slower so that the film will pack itself together. When the connections are made to produce this result the non-positive friction drive connection 38 is interposed in the shaft 38 to allow for slip and to prevent buckling of the film within the receiving member. As some of the films are shorter than othersand consequently their diameter, when wound up and placed upon reel 20, is smaller-one or more rings or collars 21 of desired thicknesses may be provided which may be inserted within the receiving member as shown in section in Fig. 5 before the beginning of the operation to compensate for this difference. After the .film has been entirely unwound from the reel 20 it will have been coiled up within the receiving member with its end which was originally on the inside of the reel 20 now on the inside of the coil'within the receiving member. The bridge-piece 14 of the supporting frame may now be removed, and the wound up coil replaced upon the reel 20 or placed upon another similar reel, one side of which is made removable for this purpose. A reel so constructed is fully described in a pending application for patent filed by me March 31st, 1908, bearing Serial Number 424,312.

I have shown my invention as applied to a moving picture machine as this forms a convenient example and illustration of its operation and use. I by no means wish to limit myself to this particular use as the invention is applicable to many other forms of apparatus; in fact to nearly any case where a reel of material is to be coiled or wound up a plurality of times in the same direction or order. The perforated paper rolls of mechanical players is an example of such use. In such devices the rollers when used are wound up on a reelor spindle and have to be unwound to get them again in proper position for being. used.
