UNITED STATES EARLE M. WOODEN, OF YONKERS, NEW YORK.

MOVING-PICTURE MACHINE.

Specification (pf Letters Patent. Patented Sept-26, 1911;

Application filed October 27, 1910. Serial No. 589,477.

Be it known that I, EARLE M. VOODEN, a citizen of the United States, residing at Nepperhan, in the city ofYonkers and State of New York, have invented certain new and useful Improvements in MoVing- Picture Machines, of which the following is a specification.

The invention relates to moving picture machines comprising the several parts and combinations of parts necessaryto display pictures from a movable film.

The various other objects of the invention will be more'fully'set forth in the following description of one form of machine embodying the invention, which consists in the new and novel arrangements and combinations of parts hereinafter setforth and claimed.

. In the accompanying drawings: Figure 1 represents a side elevationof my improved moving picture machine. Fig. 2 represents a front elevation of the same partly in section. Fig. 3 is an enlarged front elevationof the framing mechanism; Fig. 1 is a side view of the same on the line 4 '4 of Fig. 3. Fig. 5 is a front view of the shutter mechanism. Fig. 6 is a side elevation of the same.-

Figs. 7 and 8 are detail views showing different positions of the shutters. Fig. 9 is a front view partly in section of. the take mechanism. Figs. 10 and 11 are detail views respectively of the take up mechanism.

The machine is provided with a solid f head or frame 1, since no sliding parts are required, having bearings for the main shaft 2 which is operated by a crank 3. All of the parts of the machine are driven through suitable gears or trains of gearing from the main shaft, and all of the parts are-soarrangedwith relation to the head or frame that they may be detached independently of the various other working parts, so that replacements and repairs can be made with a minimum expense and delay.

The upper feed sprocket receives the m 5 from a suitable holder (not shown) and is driven from the main shaft by a suitable train of gears 6. An intermittent feed sprocket 7 is driven by a Geneva movement 8 of any well known construction, which is actuated'fromthe main shaft by the train of gears 9-9 and the gear 10, which meshes'with the gear 11 of the said Geneva movement. 'The film then passes downwardly over the lower feed sprocket 12, which ismounted on a'shaft 14 having ranged on opposite sides of a frame of plates 19, which is detachably secured to the head of the machine, and has the aperture 20 provided therein, which is intermittently opened and closed by the shutter as hereinafter described. Each shutter member 18 is secured to a shaft or pin 21 mounted on the frame 19 and provided ith a gear 22, the gears of each pair meshing with each other. The

shutter members or segments on the same side of the plate are arranged diagonally opposite each other with respect to the aperture. The shutters are operated from the countershaft 17 which is provided with a miter gear 2 1 meshing with'a corresponding gear 25 upon a vertical shaft 26 mounted in brackets 27 provided in the frame and having a miter gear 28 at its upper end meshing with a corresponding gear 29 which drives a gear 30 that is in mesh with one of the .gears 22 of the upper pair of shutter members. Said gear 30 also meshes with a correpaid of shutter members.

The Geneva movement 8is mounted in a swlnglng carrler or oscillating frame 34 which is pivoted concentrically with the driving gear '35 of said movement. The intermittent feed sprocket 7 is connected with the star wheel 36 of the movement and is driven intermittently thereby. Since the frame is "pivoted concentrically with the driving gear it is evident that the frame can be swung in the arc of a circle without disengaging or interrupting the operation of the Geneva movement and furthermore that any such swinging or oscillating move ;ment will tend to raise or lower the film which may be secured to the teeth of the feed sprocket 7. Consequently the picture may be framed with relation tothe aperture 20.

The frame is controlled and adjusted by means of an arm 37 which is pivoted to the frame and to one arm of a hand lever 38 pivoted as at 39 to the head of the machine. This lever is provided with a stud or projection 4.0 movable in a slot 41 in the head s'ponding gear 31 which operates the lower and having a thumbscrew 42 thereon which 44:, which, in my improved mechanism, is

mounted loosely on the shaft 14:. Said pulley is secured by any suitable means to a box or casing 45 having a bearing upon a sleeve or bushing 46 upon said shaft 14:. A

' spring 17 is mounted within the box 455 and r, means as the pin 48 secured in the sides of.

has one end secured thereto by any suitable the box. The opposite end of the spring is secured by any suitable means as the screw 49 to the said sleeve or bushing 46, which is secured to or formed integral with a ratchet 50. Said ratchet is normally engaged by a pawl 51, which is supported upon an arm 52 secured to or formed integral with the hub of the gear 15. Said pawl is normally held in engagement with the ratchet by means of a spring 54 and has its free end 55 normally held in engagement with a flange 56 forming part of a frame 57 mounted and longitudinally sliding upon the shaft 14. The opposite end of said frame comprises a corresponding flange 58, which is provided with a cam for beveled projection.59 which is adapted to engage with a cam or oppositely inclined projection 60 provided upon the sprocket wheel 12. The pulley 14 is normally driven through the spring 47 which permits a certain amount ofadjustment with respect to diflerent degrees of tension upon the film between the sprocket wheel 12 and any mechanism which may be contained in the receiving box. When, however, the mechanism in the receiving box which is driven from the pulley'tet exerts an undue tension upon the film, it causes a slight independent rotation of the sprocket wheel 12', which is loosely mounted on the shaft 145 and is n0rmally driven by a spring 61 secured by one end to the shaft and by the otherend to the sprocket, which independent movement of the sprocket forces the frame longitudinally on they shaft 14;.31Ild releases the pawl 51 from the ratchet 50,'whichis held, however, against reverse movement under the tension of the spring by means of the. catch 62 so that the pulley will continue to be driven and the wind up mechanism operated thereby solely... under the tension of the spring. Any suitable means, as the spring 63 arranged between the hub of the gear 15. and the flange, releases thepawl and.

permits same to engage the ratchet as soon as the tension on the film is relieved.

The operation of my improved machine will be readily understood from the foregoing description. After the film has been adjusted upon the feed sprockets. the machine is operated by the crank 3 upon the main or driving shaft from which all of the other parts of. the machine are driven.

The several movements and operations are automatic, except the framing of the picture, which is readily accomplished during the operation of the machine through the hand lever 38 which, when the proper adjustment has been made, is firmly secured in place by the thumb screw 12. The Geneva movement may be of any well known or preferred construction, and any extended statement of its operation is unnecessary.

By this construction the head or frame if the machine maybe made of a single casting, since no sliding parts are required for the purpose of framing the picture. Furthermore the framingmechanism permits an accurate register between the aperture and the picture printed on the film to be made much more quickly and expeditiously and with very much less movement of the-film than is possible by any structure wherein such adjustment is made by the means of sliding parts movable in the frame. The arrangement of the shutter reduces the time during which the shutter is passing across the face of the film to an exceedingly brief interval since each shutter member covers approximately onequarter of the aperture and the shutteropens from the center of the aperture toward the sides instead of passing diagonally entirely across the aperture as in the case ofthe shutters heretofore used. By means of this construction also the tearing of the film due to non-synchronous op. eration of the lower feed sprocket and the take up mechanism is entirely avoided, since the moment any serious tenslon is exerted on the film the feed sprocket is. caused; to rotate slightly, thus instantly relieving the tension and at the same time the driving pulley or other driving device for the take up mechanism is disconnected from the driving gear so that tension upon the film is effectually released. At the same time, however, the driving pulley or similar devicedoesnot come to a complete stop, but continues'to operate at least for a short period by reason of the remaining tension in the spring, which connects the pulley with the driving gear.-

It is obvious that various changes within the skill of the mechanic may be made in the -mechanism herein set forth,

said driving gear and having movement independent thereof, a pulley yieldingly connected to said driving gear, a clutch mechanism between said driving'gear and pulley, and means for actuating said clutch when the feed sprocket is rotated independently of said driving gear. w I
