6 is a detail View, partly in section and partly fragmentary, of the telescopic rameofthe lens, and Fig. is a side view of a slide' used in the knetoscope.

Thekinetoscope l() has a vertically disposed frame l1 and a reflector 12, which may be supported upon a suitable base-plate, as 13.

y The ramell is composed of a front-plate 14,A

and side-plates 15 and 16 which are preferably disposed at'jan angle with respect to said front-plate. In the front surface of the plate 14 is a vertical groovel', and through the upper part of said plate centrally of the groove is an opening 18Fig. 4, through vwhich the light from the reflector 12 is directed u on the pictures of a 18 as by dotted lines, for projection upon a screen.

A door 19 has one of its edges hinged, as at 20, to one yside ofthe frame 11l so that it may belswung to and fro in ,front of the opening 18 of the front-plate 14, and to allow said door to be held in locked-engage ment when closed lbefore :the opening upon its opposite edge isa clipy or finger 21 which is adapted to engage a catch 22 `provided upon the side-plate 15 of the frame.

-'.lhro'ugh. the door 19 is an opening which is in register with the opening 18 of the frontplate 14, and upon the peripheral edge of said opening is-provided. a projecting part 24 in which is'held aV telescopic frame 25 ywhich carries one or more lenses,as 26. The telescopic frame 25 consists'of two tubular members or parts 27and28. One enel of the part 27 is` held rigidly inthe yprojecting part 24, and in its opposite end is slidably held the part By'thisarrangement the part 28 may be adjusted so as,` toproperly focus the pictures from the film upon a screen, and to .firmly hold the tubular part 28 within the part 27 when adjusted adjacent to one end of said part 28 is provided one or aplurality' of friction-clips, as 29, which are `adapted to engage the-innersurface of the tubular part 2 Adjacent to the lower edge ofthe door is a gate 30, one edge of which is hinged, at 31,

to the iranien, and upon its opposite edge isi' s gage a catch 32 provided upon the side-plate arms of the U is `a roller 31 which is resiliently held tothe gate by tivo curved springs 32 and 38 which normally vserve to force said roller towardth'e -lframe 11 and in contact with ajsproclretdru'm, as will be hereinatter more 4.fully described.

`ln theside' plates 15 and 16 of the frame 11 is`journaled a drive shaft` 34 'one end of' which extends some distance from the' side plate'15, and upon the projecting end of said drive shaft is a crank handle 35 by which the machine is manually' operated. in proximity tothe crank handle 35 and upon the drive shaft -84- is la large gear wheel 3G which is inv meshwith a pinion '37 held upon one ,end ol a second shaft 38 also journaled inI the sideplates 15 and y'16'-oftl1e frame. vThe opposite endet' the shaft38 extends beyond the sideplate 16,and upon said end is a drive wheel 39. Journaled in the side-plates 15 and 1G and-in proximity to thesecond shaft 38 is a third shaft 40. Upon the third fia it 40 and between the side-plates of the fra-me is a sprocket drum-941" having-a portion of its -face projecting through an opening in the lower part of the front-plate14 ofI said frame whereby the roller 31 of the gate 30 may cooperate' with said' sprocket drum so' as to properly feed the picture lilm through the machine.- The sprocket drum 41 has the usual spaced end Wheels, as 42 and 43, upon z plurality of spaced openings45.

As a means to impart an intermittent rotation to the third' shaft 40 as well as tothe s}; rocloet'drumv 41 "so that the film may be intermittently moved during the consecutive exposures of the pictures,'l employ a Geneva movement. 45 which yispreferably of the usual form consisting ofa star Wheel 46'hav-- fing a slot 47 provided in eaehpoint thereof.

The starl Wheeli46 is'heldupon the end of' the thirdv shaft '40"which extends somedistancel beyond the side plate 16 of the frame, an'd'- upon'thelsecond shaft 38is a` disk 48. The' disk 48 isl substantially circular in shape and projecting from one of its faces-is a pin "49fwhiclr isfadaptedy to'be guided into each of the4 slots'y offthe star Wheel 46 When the'diskis revolved' so that' said star wheel chine is'operated.

In the'groove 17 'of the front-plate 14 is a slide 5011i' Whieh-isy a ,Window 51,1gFig. 4.

lwill be intermittently rotated when the ma- `The slide-'50 is adapted` tobeadju'sted so'l 'that the Windowil will normally be in-register with the opening 18ct the front-plate' 14 and in register with the passage through the-telescopic -frame 25- in order that the pictures of the i'lm may be accurately trained previous to being focused by the lens 26.

lThe slide 50 is held against displacement film-guide 53, and upon arod 5t extending above ,said frame is a reel which may be of the usual form for Winding the picture film thereupon. Thepicture film 18a may be in the usual form of a strip of desired length, or its ends may be connected so as to form an endless band. In applying a picture film to the kinetoscope it is trained over the reel and guided in the vertical groove 1T of the front-plate 14 after the door 1f) and gate 30 have been swung open. rlhe film is then arranged on the sprocket drum 41, and after the door 19 and gate 30 are closed upon the frame 11 the film is disposed through the guide and the machine may be operated by the crank handle 'To permit preferably an electric lamp. as indicated by dotted lines at 5G, to be used' in conjunction with the kinetoscope for projecting the pictures of the film so as to avoid the use'ol:l a light produced by ignited acetylene, or other explosive gases or liquids, I provide thelight reflector 12. The reflector 12 is composed of a tapered tubular reflector 58 the small end of which is fastened in the opening 18 of the front-plate'14 ol the frame 11, and upon the opposite end of said tubular reflector is a reflector 59' of a concave or parabolifor'm shape. The reflectors and 59 may be made integrally, or separately and detaehably held together, as illustrated. Centrally of the concave reflector 59 is an opening O0, andupon the exterior surface of said reflector at the opening therein is a short tube or boss 61 adapted to removably hold the' plug of an electric lamp. The tapered tubular reflector 58 and the concave reflector 59 may be made of metal having the interior surface thereof plated with highly polished nickel or silver, or mirrored glass may be used instead of the plating, as shown at 62. Obviously by using this form of' reflector the rays of light from an electric lamp willA be reflected by the'concave reflector 59 to the reflector 58 from' which said rays Will be' intensified and deflected through the opening 18 'ofthe front-plate 1G and through the- Win'dow 51' of the slide 50 upon the pictures of a lm. 'Thus an electric lamp of limited candle power, for instance, such as may be produced from dry-cell batteries which may be -carried inany suitable form of casing, as G8, may be used, or the Wires 64 of the lamp may be connected to any other source of electric supply.

In the foregoing description I have embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that .modifications may be made therein without de- A parting from the principle or sacrificing any of the advantages of this invention, therefore I reserve to myself the right to` make such changes as fairly fall within the scope thereof.

' Having .thus 'described my invention, I'
