KINEMATOGRAPH APPARATUS.

mes es.

play of kinematograph pictures is consider ably reduced.

The improvements are illustrated in the accompanying drawing which will now be scru 1 I11. v y

A re 1, is a side elevation partly in section of a shutter film gate and tunnel. l1 ig. 2, a. sectional plan on line A A, Fig. 1, Fig. 8-, a perspective view of a cap of a shutter casing and a lens holder, and Fig. 1, a perspective view of the shutter.

Referring to the drawing the film is fed through a film gate 3 in front of the light from and behind a lens 5, the feeding m0- tion of the film gate being obtained in the ordinary way.

The driving gear of the apparatus is connected by suitable gearing with the spindle an or shutter 46 inclosed in a shutter ing 47 fixed to the frame 18 of the mach no, and having a cap 19 secured by 50. The shutter 16 is cylindrical and metrically opposite apertures 51 and 4c 52. ilridge pieces 55 and 56 unite the rims 57 and to the rear part 59 of the cylinder.

Application filed December 4, 1912. Serial No. 734,805.

The film gate 31sec more particularly Figs. 1 and 2) is pivoted by screws or pins 81 and 82 to brackets 83 and 84 extending laterally from a. slide 86,slidable in grooves formed in the back of the casing 17. Friction bars 89 and 90 carried by the gate 3 consist of wires having their ends bent at a right angle and passing through the gate. Flat springs 91 and 92 are secured to the gate at their middle part by screws 98 and 94 and bear respectively upon the upper ends 95 and the lower ends 96' of the friction bars 89 and 90 insuring an equal pressure upon the lateral sides of the film. lVhen the film gate is closed upon its mouthpiece 97. the bars 89 and 00 enter the recess 98 of the mouthpiece and bear upon the film with equal pressure, owing to the springs 91 and 02 being secured at their middle part as described. The gate is held in its closed position by means of slides 100 and 101, which have slots 102, whereby they are slidable upon screws 103. Catches 10% and 1043 upon the slides are adapted to engage lugs 106 and 107 formed upon the g; e 3.

The slides 100 and 101 operable by a button 108 secured upon a spindle 109 which is provided with arms 110 engaging notches formed in tl e slides 100 and 101. The slide 86 is fixed to the mouthpiece 112 of the tunnel 113 of the lantern house. lVithin this tunnel is arranged a fall down safety shutter 114- which automatically controls the admission of light from the lantern.

The film is readily placed in position within the film gate by witluilrawing the termination of the tunnel 113, which telescopes upon the base 126 of the'tunnel. The film is thus merely passed laterally into position into the gate 3 without the necessity of threading the film endwise through these parts. Byfixing the mouthpiece 112 to the slide 86 the end of a broken film is prevented from entering the tunnel and being ignited by the lamp.

lVhat I do claim and desire to secure by Letters Patent of the United States is 1. In lrinematograph apparatus, a cylindrical casing having opposite apertures. a cap upon the casing, a sleeve upon the inner face of the cap. a lens carried in the sleeve, a cylindrical shutter surrounding the lens and ice. ted in said casing and having apertures and blanks, and means for rotating the shutter.

2. ln kinematograph apparatus, a oylin drical casing having opposite apertures, a cap upon the said casing and having a groove, a slide fitting the groove, a sleeve carried by the slide, a lens carried in the sleeve, means for moving the slide laterally, a cylindrical shuttersurrounding the lens and located in said casing and having apertures and blanks and means for rotating the shutter.

3. In kinematographapparatus, a cylin drical casing having opposite apertures, a cap upon the said casing and having a groove, a slide fitting the groove, a sleeve carried by the slide, a lens carried in the sleeve, a lug upon the slide, a hood covering the lug, a screw passing through the hoodand screwed into the lug, a cylindrical shutter surrounding the lens and located in'said casing and having apertures and blanks and means for rotating the shutter.

4. ln kinematograph apparatus, an aper turedcasing, an apertured shutter located therein, means for rotating the shutter, a mouthpiece on the casing, a slide having brackets adapted to be moved toward and from the mouth piece, a film gate pivoted to said brackets, and means for attaching the film gate to the mouth piece of the said casing.

5. In kinematograph apparatus, an aper' tured casing, an apertured shutter located therein, means for rotating the shutter, a mouthpiece on the casing, a slide having brackets adapted to be moved toward and from the mouth piece, a film gate pivoted to said brackets, vertical friction bars having right-angled ends passing through the gate, horizontal springs projecting the top ends and lower ends respectively of the said bars through the gate and means for attaching the gate to the mouthpiece.

6. In kinematograph apparatus an apertured shutter casing, an apertured shutter located therein, means for rotating the shutter, a mouthpiece on the casing, a slide having'brackets adaptec to be moved toward and from the mouthpiece, a film gate pivoted to said brackets, vertical friction bars having right-angled ends passing through the gate, horizontal fiat springs secured to the gate at their middle part and having their ends hearing upon the ends or the friction bars, and means for attachingthe gate to the mouthpiece.

7. In a kinematograph apparatus an apertured shutter'casing, an apertured shutter located therein, means tor rotating the shutter, a mouthpiece on the casing, a slide hav ing brackets thereon adapted to be moved toward and from the mouthpiece, .i film gate pivoted to said brackets, slides upon the mouthpiece, a spindle carried by the casing, arms on said spindle adapted to engage slots in the mouthpiece slides, and catchesupon the film gate adapted to be engaged by the slides.

8. n1 kinematograph apparatus an ape tured casing, an apertured shutter located therein, means for rotating the shutter, .a mouthpiece on the casing, a slide, having brackets thereon adapted to be moved toward and from the mouthpiece, a film gate pivoted to said brackets, slides upon the mouthpiece, spindle carried by the casing, rrms on sa d spindle adapted to engage slots in the mouthpiece slides, catches upon the film gate adapted to be engaged by the slides, and a telescopic tunnel through which the light enters, the termination of the tunnel being fixed to the firstanentioned slide.

9. ln kinematograph apparatus, an apertured shutter casing, an apertured shutter located therein, means for rotating the shutter, a mouthpiece on the casing, a slide having brackets thereon adapted to be moved toward and from the mouthpiece, a film gate pivoted to said brackets, slides upon the mouthpiece, a spindle carried by the casing, arms on said spindle adapted to engage slots in the mouthpiece slides, catches upo the film gate adapted to be engaged by the slides, a telescopic tunnel through which the light enters, the termination of the tunnel l)! ing fixed to the first-mentioned slide, and a fall down safety shutter Within the tunnel.

In testimony whereof I have signed my name to this specification in the presence of two witnesses.
