SAFETY ATTACHMENT FOR KINEMATOGRAII-IS.

Specification of Letters Patent.

Patented June 23, 1908.

Application filed October 29, 1907; Seriai No. 399,718.

To all whom it may concern:

Be it known that I, ARCADE MALLET, .a

public of France, have invented a new and useful Safety Attachment for Kinemato- .graphs, (for which I have obtained a patent in France, No. 371,008, bearing date Octo-- ber 31, 1906); and I do hereby declare the following to be a full, clear, and exact description of the same.

The present invention has for its object a device which enables to stop automatically,

the burning of the strips of films employed in kinematographs when they have become accidentally ignited. 4 Y

The drawing annexed to the present specification shows, by way of example, a mechanical device in accordance with the present invention.

In this drawing: Figure 1 is a front elevation of the arrangement as a whole, with the I covers of the boxes removed. Fig. 2 is. a

partial sectional front elevation, on a larger scale, representing the device in the open position. Fig. 3 is a corresponding elevation, in the closed position, and finally Fig. 4 is a side elevation of-the device shown in Fig. 2, on the lefthand side of this figure.

The same reference numerals represent the same elements in the various figures.

In this system, the film spools 1 and 2 (Fig. 1) are respectively inclosed in hermetically closed boxes 3, 4, which are fixed at their bottoms to the spindle of each of the spools, which are carried in the ordinary manner. Each of the boxes 3, 4, terminates, at the place'at which the film leaves it, in a nozzle 5. The film is led in the ordinary manner overthe various driving rollers 8, from one spool to the other.

The device by means of which the burning of the film may be stopped automatically is constituted in the following manner; upon the nozzles 5 of each of the boxes 3, 4, or at some other place on those boxes, there are mounted rods 18, the len th of which is adjustable at will, and which end in a knob 19 by means of which a strip of celluloid or any other inflammable matter 21 is'stretched, this strip serving to keep open spring obturators 20. These obturators 20 are of such a form that the strips of inflammable matter 21 are almost contiguous to the stri of film 17, from which it follows that if t e latter should become ignited owing to this proximity the strip 21 is immediately kindled likewise so that it no longer retains the correimmediate closing of the latter and consequently the cutting off of all communication between the outer strip offilm and the inner spools.

What I claim is:

film in a kinematograph, comprising magazines provided with nozzles, spring obturators cooperating therewith, and an inflammable strip in proximity with the film, holding open the spring obturators, whereby ignition of the film will ignite the strip and release the obturators,
