To all whom it may canoem:

Be it known that I, W. San- MON, J12, a citizen of the United Status residingat Baltimore, the-State Maryland, have invented certain new and useful Improvements in lllotien f'ic'tum Apparatus, of which the following isa specification.

This invention rel-ates to motion-picture Y apparatus and particularly to'the reel mech- 10 anism therefor.

One object is to provide a reel adapted to be mounted upon an incline and loosely support a coil of film in "m'bstantially edgewise position thereon, with means arranged the interior of said same upon the exterior operation of the macoil and rewind the ture machme and subsequently directing the film from the machine back to theouter convolution of the film coil on the reel, whereby the film is wntinuously unwound and rewound on the one reel.

. Another object ot-the invention is to join ofseparate films, so be projected that, combined, they may through the machine continuously without "18 the angle plate manipulatlon or intermission.

, A still further. obiect is to provide a comparatively simple and economical film reel embodying revoluble rin'g' members capable of revolving together or independently of each other and adapted to be engaged by the these revoluhle ring members rather than on the bottom oi the reel.

. With the above and other objects in view,

the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustratedin the 'accompanymg drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details :W1tl'1011t departing from' the spirit '9!- sacriincludes a tubular lens lower guide rollers with means arranged from the. innermost chineA in any angle plate 16, one web 1 the machine A and by tightening the his to one of edges of'the film to support, the latter so that most of the weight of the film is carried by I 21" and upWarlly and rearwardly in a plane substantial y ficiig any of the advantages of the invention.

In the drawings :-Figure 1 is a view illustrating a motion-picture machine in side elevation and my improved reel in perspective. Fig. 2 is a front elevation of a movleg-picture machine apparatus illustrating my improved reel in perspective. Fig. 3 is a sectional view of my improved reel. Fig. t is a transverse sectional view of. the reel. Fig. 5 is a face view ofthe reel. Fig. 6 is a detail fragmentary section of the reel supporting arm illustrating the supporting surface for the reel.

Referring now more particularly to the accompanying drawings the reference character Aiudicates a moving-picture machine which may be of any suitable type and'which holder 10, upper and 1111 and 12-12, respectively, which connected together'in any suitable manner so that upon operation of the handle 12 mounted on the shaft 13 and by virtue of suitable connections between the shaft 13 and the guide roller 12 the film 14; may be driven or fed through the machine for the projection of the picture in theusual man:

ner.

Mounted on top of the casing of the masuitable manner is an arm 15 arranged preferably perpendicularly. Along the upper front edge ofthe casing of the moving-picture machine A is disposed an of which has slots down over the front face of the casing of thumb nuts 18 this plate 16 may be clamped firmly to the casing of the moving-picture machine. the'webs of this angle plate 16that the perpendicular arm 15 is pret erably secured. One means for securing the perpendicular armr15 to'the plate 1615 to provide the arm 15 with afoot piece' 19 through which" may be passed one or more bolts 20 so as to fasten the arm lo firmly on the plate 16.

The upper end of the perpendicular arm 15is preferably enlarged as at 21 with its enlarged portion provided with a flat face which face is preferably inclined at aforty-five degree angle with are preferably suitably 17 whereby upon lOOSBIHIIg the thumbnuts 16 may be readily fitted relation to the axis of the perpendicular arm 15.

The flat face 21' at the upper end of the supporting arm 15 provides a supporting surface for the film reel B. This film reel B may be of any suitable construction. It

'ride upon the trunnions 25 of the rollers 26 are spaced rings 27 and 28 against the inner faces of which the edges of the film C are adapted to bear so that when the film is driven through the machine in a manner hereinafter explained the edges of the same may engage either one or the other of the rings 27 and 28 and cause them to rotate. The film is arranged loosely over the rollers 26 and they are supported mainly on their edges by the revoluble rings 27 and 28 incident to the inclined disposition of the reel and the winding and unwinding of the To support the film reel B on the inclined face 21' of the head 21 of the perpendicular supporting arm 15 the annular flange 27 maybe provided with a headed projection 29 adapted to be easily removably seated in the notch 30 at the upper edge of the head 21 with the head 21 having projecting from its flat face 21' the pins or studs 31 designed to engage against the outer face of the bottom portion of the annular channeled member which forms the body of the reel. 'In this way the reel is hung or suspended from the upper end of the perpendicular arm 15 and thereby firmly supported in operative position.

As the-film coil on the reel B is rotated the inner convolution is directed from the reel out through the film passage 24 in the reel to and over the guiding element 32 which is preferably in the form of a roller, as shown, and which projects from the flat face 21' of the head 21 at substantially a right angle to the longitudinal axis of the arm 15, extending into the area bounded by the bottom of the annular body member of the reel and preferably midway of opposite sides of said body member on an imaginary horizontal line adjacent the bottom edge of the film passage opening 24. From this guide roller 32 the film, is driven by the driving mechanism between the aforesaid shaft 13 and the guide roller 12 and the driving connections being element 32 with the guiding elements 32 and 33 arranged at an angle with relation to the plane of the guide rollers 11-11' and 12-12 so that the run of the film which extends beyond the guiding element 33 may be deflected to one side of the tubular lens holder 10 so as not to interfere with the picture projecting from that part of the film passing between the guiding rollers 1111 and 12-12. The film is continued upwardly from the guiding element 33 off to one side of the tubular lens holder 10 as just stated to a guiding element 34 which latter is preferably disposed in a parallel plane with the guiding element 32- and which guiding element 34 is preferably carried by an arm 35 secured to the perpendicular arm 15 in the rear of the head 21, as shown. This guiding element 34 may be secured in any suitable manner on the interior of the usual film magazine casing (not shown) instead of being secured to the arm 35, as specified. In any event, the

function of the guiding elements 33 and 34 is to direct the film back to the reel so that it may be returned to the outermost convolutions of the film coil on the reel B.

It will thus be seen that I 'provide a film reel and means for guiding the film whereby the film coil on the reel may be loosely carried thereby and directed from said reel from the innermost convolution of the film out of the plane of the reel to the motionpicture machine and then guided from the machine back to the outer convolution of the film coil on the reel whereby the film is continuously unwound and rewound on the one reel. The result is that I obviate the practice of unwinding the film from one reel to another and subsequently shifting the positions of the reels to repeat the pictures. By virtue of my improved reel I am enabled to provide for a- .continuous performance by continuously winding and unwinding the film on the one reel, thereby obviating the necessity of shifting one reel with relation to another and also rendering it possible to simply remove the reel with its film thereon at the end of a performance and substitute another reel with a film thereon and continue to wind and unwind the film on the one reel until the end of the performance.

What is claimed is 1. In a motion picture apparatus, a reel, means for supporting said reel, means for winding and unwinding a film thereon, rollers journaled in said reel and rings rotatable upon the trunnions of said rollers. j

2. In a motion picture apparatus, a reel, means for mounting said reel, means for winding and unwinding a film thereon, said reel comprising two sections, means for removably connecting said sections, parallel flanges formed upon said reel, in spaced relation to each other, said flanges having openings provided therein, rollers journaled in said openings and rings rotatable upon the trunnions of said rollers and slidably engaging the outer ends of the rollers. and inner sides of the flanges, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
