Specification of Letters Patent.

Patented Nov. 17, 1914.

Application filed June 5, 1909. Serial No. 500,417.

To all whom it may concern:

Be it known that I, AnoLrH F. GALL, a

citizen of the United States, and a resident of West Orange, in the county of Essex and State of New Jersey, have made a certain new and useful Improvement in Kinetoscopes, of which thefollowing is a description.

My invention relates to kinetoscopes and the object thereof is to provide simple and efficient means for protectin the film against the possibility of ignition rom the heat of the source of light of the machine, and novel means for latching the same in open position.

More specifically, my invention comprises a door provided with the usual projection aperture and an auxiliary hinged screen or film protecting device below the said door for protecting that portion of the film which extends below the bottom of the door against the possibility of burning. The screen is provided with means coacting with the door when both are in open position to latch the same in suchQposition, so that the screen is unla'tched when the door is closed. As the screen is provided with suitable means as a spring for closing the same when it is otherwise free .to close, and as the door must be closed in order to operate the machine, 1t s evident that by my invention a device 1s provided whereby an operator is prevented through carelessness or indifference fromv leaving the, lower filmprotecting screen in open position. Preferably, the door'carries anupper film protecting screen above the same, so that in a device constructed accordmg to my invention, the film is protected against the heat of the lamp throughout its entire passage through the machine.

Other objects reside in the construction of parts and combinations of elements, all as hereinafter described and more particularly pointed out in the appended claims.

Reference is hereby made to the ace-011 1: panying drawings forming part of this specification, in which corresponding parts are indicated throughout by the same refer-. ence characters, and in which Figure 1 is a rear elevation of the head of a kinetoscope embodying my invention, the film protecting door and screen being shown in closed position; Fig. 2 is a side elevation of the same looking from the right in Fig.

. for kinetoscopes.

1; Fig. 3 is a view similar to Fig. 2, the door and; screen referred to being shown in open position.

Referring to the drawings, the kinetoscope head 1 is provided with a door 2 which is provided with a film protecting fire screen 3 protecting the projection aperture in the said door and designed only to open to expose the film through said aperture when the machine is in operation and the film passing said opening at a proper speed. Th s device may be of any approved character, and I have shown the same as the automatic fire screen described and claimed in my Patent No. 998,571 dated July'18, 1911, for automatic film protecting screens The door 2 is pivoted at its rear edge on the vertical pin 4, and is provided at its front edge with a locking device of .any approved character, the device illustrated consisting of a vertical slide 5 carrying the latch 6, the said latch cooperating with a projection on the frame of the machine to secure the door in closed position, and the said slide-5 being provided with a thumb piece 6 to unlatch the door. The door 1s also provided with the usual springs 7 for tensioning the film and the rollers 8 coacting when the door is closed with feeding devices in the machine, the door also carrying the other usual parts. The door 2 is also preferably provided with an upwardly projecting film protecting screen 9 carried by the door and extending above the same to protect the upper portion of the film, and a downwardly projecting film protecting member 10 de pending from said door.

The film protecting screen 11 is provided below the door 2, the said screen being hinged on the vertical pin 12 at the rear edge of the screen, suitable means being provided for automatically closing the screen 11, as the'spiral spring 13, which is shown as coiled about the pin 12 and so arranged as to force the screen 11 into closed position. Thus the screen 11 is biased into closed or film protecting position. The screen 11 is formed to overlap the lower edge of the portion 10 of the door 2, the upper edge of screen 11 being curved toward the front of the machine,- as indicated, to rest against the rear surface of the portion 10 of the door 2 when the screen and door are closed.

for raising the slide The upper edgeof the screen 11 is provided with a notch 14 shaped as indicated in the .drawings, the result of this construction be ing that when the door and screen 11 are opened for the purpose of threading a film through the machine, or forany other purpose, the front edge of the portion 10 of the door 2 may be placed within the notch 14. As screen 11 has a constant tendency to close, due to the action of spring 13, the edge of notch 14: constantly presses against the front edge of door 2, binding the parts firmly in open position, since the notch 1% is so positioned that the edge of door 2 only enters the same when the door is in such position that the pressure of notch 14: upon the edge of thesame is exerted in a plane parallel to thevsurface of the door in such position. Furthermore, notch 14: 1s so shaped as to hold door 2 against closing While the edge thereof is retained within the notch. To close the parts, the screen 11-is pushed farther back a small distance, whereupon door 2 is. free to close, screen or shield 11 thereafter closing automatically as soon as it is allowed to do so. 7

It is obvious that various modifications may be practised in my invention without departingfrom the spirit thereof. For example, it is evident that the pos1t1on of the co-acting latch members on the screen and door mightbe interchanged with similar results, or that a screen similar to screen 11 might be independently mounted above door 2 with similar latching means to that described.

Having now described my invention, what I claim and desire to protect by Letters Patent is as follows:

1. In a kinetoscope, the combination w th a film protecting door having a pro ect 1on aperture, of a movable protecting screen overlapping the sald door, means tending to close said screen, and means for latching said door and screen 1n open position unlatched by the closlng of the said door, substantially as described.

2.In a kinetoscope, the combination with a film protecting door having a PIOJGCtlOD. aperture,
