MOVING-PICTURE MACHINE.

city of Weehawken'icounty of Hudson, and

State of New Jersey, have invented certain new and useful Improvements in Movin Picture Machines, of which the following 1s a s ecification;

ur present invention relates to an improved moving picture..'.machine having obj ects andadvantag's which will appear from an understanding of the annexed specification and drawings.

In the drawings which show only one-o the forms which our improvements may take,

Figure 1 is a side elevation of a moving picture machine embodying our 1mprove-' ments, showing parts thereof broken away; Fig. '2 is a rear elevation of the same, likewise showing parts broken away; Fig. 3 is a vertical section, partly in elevation, on the line 3-3 in Fig. 2 looking in the direction of the arrow Fig. 4 is a horizontal section partly in plan on the line 4-4 in Fig. 3; Fi 5 is a diagrammatic view ofa detail; an Fig. 6 is an elevation of the film track plate detached from themachine. Describing now our improvements with )articular reference to the devices of the drawings, and reserving it to the claims to point out the novel features, the machine shown com rises a base or foot 1 with side frames 2, ront 3, and back 4,'.said back being hereinafter referred to as the film track plate.

Pro ecting out from the front 3 of the machine is any usual or preferred lens or rojecting device 5. At the rear of said device is an, opening 6 in the film track plate, said opening in width being adapted tothe width of the film and having a vertical height greater than the height of the individual pictures, preferably considerably cater, for a purpose hereinafter described. The film track plate 4 has a recess or track within which the film travels, extending vertically across the plate. Theopenlng 6 pref viously referred to is located in the bottom of this recess ofwhich the sides 7 are best; seen in Figs. 4 and 6 and serve to guide the film at its edges. i In the particular machine shown the film,

designated 8, is received fromabove and travels down through the film track and outwardly from its bottom. The driving mechanism for the film will be subsequently described.

On the rear side of the film track plate are verticall extending guides 9 which re.- c'ei've sliding y between them a slide 10 (com- Patented July 5, I910.

pare Figs 2-a'n'd- 4). Said slide hasa Will',

dow 11, adapted as the slide is adjusted up and down relative to the film track plate and its opening 6, to vary or adjust the up'and down location of the pictures as projected on the screen. Means for effecting this up and down adjustment ofthe slide 10 and its window comprises rock-shaft 14 journaled' across between the side frames 2 of the machine, said shaft having a squared end 15 to receive an operating handle 16 and centrally having projecting pins 17, the ends of. which are loosely received suitable openings inthe slide 10, whereby, turning the'handle in one direction or the other swings the pins through an arc to correspon ingly raise or lower the slide and consequently its window, relative to the opening 6 in the film-track plate.

To-yieldingly bear against the edges of the film and retain same in the recess of the track-plate aresprings carried by the slide 10. In the particular devices shown there are two sets of these springs (compare Figs. 2 and 3) the upper setcompnsing a pair of leaf springs 18, the middle portions 18 of which 211' on the inner face of the slide and run verti ally up'and down to bear respectively in yielding fashion on the edges of the film, whereas the free ends 18 of said springs extend through suitable openings 19 in the slide. and may be secured by screws as shownto cross-pieces 20' on said slide. The lower set of sprin likewise comprise leafsprin 21 the mi dle portions 21 of which as be ore are at the inner side'of the slide to bear against the respective edges of the film with their free ends 21* in this case connected around or-throu h the slide and meeting centrally, where t ey are secured togetherto a single cross bar 22 on the outer face ofv the slide. 'It will be understood that of course these details of construction may.

be varied as for example crom-piec'es 23 can be provided connecting across the lower setof s rin at the outer face of the slide to relation to bear properly on the edges of the film.

The aforesaid springs 18.and 21 carried,

.as they are, along with the vertically adjustable slide and pressing yieldingly' on. the moving film, serve not only to hold said film recessed in the track of the track-plate,

but also to uphold the window-bearing slide in the given position of adjustment which it'may have from the operation previously described of the handle 16.

Next describing the operating means for the film, in the firstplace ashaft 24 is'provided journaled across the sides 2 of the easing at the u per part thereof, havmg a crank or han le 25 adapted to rotate the shaft and from it, as will hereinafter ap;

pear, to pro ess the filmacross the window said shaft urther carrying at its free en an exterior gear wheel -26 conveniently called the driving gear wheel or sprocket.

Above and below this drivin sprocket 26 are two other sprockets 27 an 28, all beingconnected by a commonchain 29."- Ih'e 'upper sprocket 27 is mounted on ashaft 30 .suit'ably journaled' across the-side frames and having centrally within the casing a pair of toothed disks 31, the teeth of which respectively are ada ted to engage the film openings and to d ve the film from the rotation of the disks.

An inspection of Fig. 3 shows that the film is guided under an around the toothed disks 31 by a' guard or guide '32 suitably supported in any preferred manner from the frame or casing. The delivery film reel from which the film comes is not shown as forming no part of our present-invention- Likewise' it maybe sald that the take-on reeland similarly irrelevant". arts have for the same reason been 'omitte guided above by the sides or flanges 33 of a roller'34 journaled across between. the side frames at the rear of the slide'lO, which is here verticall slotted to permit said flanges 33 of the rol er to pro'ect-throughand-be ond the inner side 0 'ithe'slide toreceive etween them and guide the travel of the "film down into the track in the track plate.

It'will be noted thatthe slide 10 may have 1ts upper end curved at 35 as shown to-conveniently direct the down -'passa'ge of the film, especially when threading it 1nto operative position in the machine. Furthermore it may be'noted that the roller 34 may have heads 36 against which the outer side of the slide 10 at its top may bear as'shown in Fig. 3. Pins 37 are shown on the slide 10 imposition to contact-with the topsof the es 9 to uphold. said. slide from passing low the lowermost position which-it is' 'ever necessary for it to have. 6

To take up the film delivered by the driv- The. film thence passes-down between-the slide" 10 and the track plate 4 as already described, being ing disks 31 and to intermittently progress it across the window is mechanism as follows.- In the first place mounted on the same shaft 38 as the lower sprocket 28 is a disk 39 carrying a crank pin 40, said shaft also carrying, as may be mentioned in passing, a fly-wheel 41. Similarly it may be mentioned that a roller 42 may be provided j ournaled on the stud from the frame in position to receive over it the travel of the chain andto act as a chain-tightening roller. Operated from the crankpin 40'is an arm 43, having a longitudinal slot 44 at its end to receive said crank pin and havin further a longitudinal slot 45 at or toward 1ts center to receive through it a horizontally extending rod 46, connected across between the side frames of themachine as best shown in Fig. 4, said rod acting as a fulcrum for said arm with and directly support the sectors.

That the teeth of the sectors may engage the film openin s, the film track plate 4 1s vertically slotte also the film contacting portions of the lower that the otherslots 54 in the plate 4 are to provide for the vertical play of the pins 17. The operation of the just described devices is as follows: When the handle 25 is turned in clockwise'direction, it drives the main and secondary sprockets in the direction of the arrows in the various figures, and

the crank pin 40 rotates withits' disk in the direction of the arrow in Fig. 3. The effect is to operate the toothed sectors 49 to give the film as intermittent progressive move-' ment, said movement comprisin complete rotation of the crank pin a quick downward swing of the sectors in drivin contact with the film followed by a perio continuing for the rest of the rotation of the crank pin during which the sectors are out of contact with the film and are being returned into initial osition for their next downward swing. his is indicated although incom letely in Fig. 5, wherein the position A o the sectors represents their initial or topmost position just before beginning their downward swing; B represents an intermediate position in the course of said. downward swing; and 0 represents a' position in WhlCh the sectors have been at 53 (see Fig. 6), as are for each '52 extending from either side which connect 'set of springs 21. It may here'be remarked the film can be varied; so. that for one complete rotation of the crank pin, the former or operative period can be made relatively short and thereforecorrespondingly rapid,

and the non-operative period relatively long,

' whereby the use of the shutter, ordinarily required in moving picture machines, can be dispensed with.

- The springs 48 serve to hold the arm 43 yieldingly. between them in any given position wherein it may be left by theoperation of crank pin 40.

Having .thus described our invention,

what we claim is:

1. In a moving picture machine, the combination of means adapted to intermittently feed the film in one direction, said means comprising teeth adapted to engage the film openings, an arm supporting said teeth at one end,. said arm having a longitudinally extending central slot and another longitudinally extending slot toward its other .end, a rod extending through the central slot and acting as a fulcrum for the arm, and a crank the pin of which is located in the end slot in the arm.

2. In a moving picture machine, the combination of means .adapted to intermittently feed the film in one direction, said means comprising teeth adapted to engage the film openings, an arm supporting said teeth at one end, said arm having a longitudinally extending slot and another longitudinallyextending slot toward its other end, a rod extending through the central slot and acting as a fulcrum for the arm, a crank the pin of which is located in the end slot in the arm; and means operating yieldingly in lateral direction against the arm.

3. In a movin picture machine the combination of amain sprocket, handle-driven;

secondary sprockets chain-connected with the main sprocket;"a toothed disk rotatable with one of said secondary sprockets having teeth adapted to engage the film. openings to deliver the film toward the window of the'machinepa crank pin rotatable with the other secondary sprocket; an arm having an end slot receiving said crank pin and further having a-central slot, and a toothed sector at its other end, the teeth of said sector adapted to engage the openings in the film on the receiving or take-up side of the window; and a rod extending through the central slot in the arm and acting'as a fulcrum. 5

4. In a moving picture machine, the combination of means adapted to intermittently feed the film in one direction, said means comprising an oscillating film-member having one end for intermittently contacting with and driving the film and having at its other end longitudinally spaced apart stops,

a member having sliding connection Wlth" the middle portion of the film-member and I acting as a fulcrum for said member, and a crank operating between said stops.
