I I Application filed January 31, 1912; Serial No; 674,498. Renewed October 12, 1912. Serial No. 725,536.

T 0 all whom it may concern:

Be it known that I, HENRY EWOLDT, a citizen of the United States, residing at Holstein, in the-county of Ida and State of 5 Iowa, have invented certain new and useful. Improvements in Fire- Extinguishers xof which the following is a specification, reference being had -to the accompanying drawmgs. I I It-is well known that many serious fires, accompanied by considerable loss of pro ert-y and sometimes by the loss of human li e, have been occasioned in moving picture theaters by the highly inflammable films conditions, my present invention'ias for its primary object a simple, durable, and efiicient construction of device which may be easily secured to the reel box of a moving picture machine, whereby, should the films take fire, some liquidor dry fire extinguishing substance may be sprayed upon the film and put out the fire.

The invention also has for its object a simple device of this character which is construoted of few and simple parts that maybe easily manufactured and readily assembled and disassembled for the purposes of refilling, cleaning, or repair and which will interfore in no wise with the proper feeding of the film. And the invention also aims to generally improve this class of devices and to. render safer the opera.' on of moving pic-- ture apparatus. v

With-these and other objects in view. as wvill more fully appear as the description proceeds, the invention consists in certain constructions, arrangements, and combinations of the parts that I shall hereinafter fully describe and claim.'- v

For a full understanding ofthe invention,

reference is to behad to the following description and accompanying drawing, in,

The container 1 is designed to be secured to one side of a reel box 2, bands 3 being prostance and'secured to one side of the reel box by bolts and'nuts l with which said bands are provided, as clearly illustrated in the 1. drawing. The upper end of the container 1,

Within the casing 9 is apreferably curved, transversely extending valve plate-13. which normally cuts off the orifices 12- from is provided with a finger knob 17 ,an a coil p of the rod 16 and bears at one end against t eme!- side of the casing, thereby. tending drawing, i the operation of my improved fire extin- 9 being secured to the lower end of the I container 1 and, owing to the screw threaded connection between the casing and the H to press inwardly upon the finger piece or knob 17, whereupon the rod 16 will he pushed inwardly .and swing the valve plate 13 out beyond the transversely extending series of orifices 12, so as to permit the fire extinguishing fluid or powder, as the case may he, to flow downwardly on the burning film to extinguish the fire.

If desired, the valve plate 13 may be formed of spring material and inwardly bowed in its operative position after it cuts oil the orifices 12 from the major portion of the casing. When it is thus formed, it is evident'that when the plate is pushed forwardly by the rod 16 and passes the orifices 12, it will straighten out and catch on the inner lower edge of the casing and thereby be held in open position against the tension of the spring 18 so that the operator need no longer pay attention to the extinguishing, apparatus but give his attention to providing for the safety of his moving picture machine.

While the accompanying drawing discloses what I believe to be the preferred embodiment of my invention it is to be understood that the invention is not limited thereto, but that various changes may be made in the construction, arrangement and proportions of the parts without departing from the scope of the invention as defined in the appendedclaims. i

Copies ofthis patent may be obtained for m catches fire, it is only purpose specified.

Having described invention what I claim is ':-I c

1. A device of the character described, including a container for a fire extinguishing substance, a casing having a screw threaded connection with the lower end of said container and formed with outlet orifices, a valve plateadapted to cut ofl said orifices from the remaining portion of the casing, and means whereby the valve plate may be pushed past said orifices for the 2. A device of the character described, including a container, a casing detachably connected to said container at one end and projecting in angular relation thereto, the casing being formed atone end,;with outlet orifices, a hinged plate carried by the cas ing and adapted to cut off said orifices from the remaining portion of the casing, an actuatin rod extending longitudinally in said caslng and operatively connected to said valve plateyand a spring tending to hold said rod in its rearward position.

-3. A device of the character described, including a container, a casing connected thereto and formed at one end with outlet orifices, a normally bowed spring valve plate mounted in said casing and adapted to cut off the orifices from the remaining portion of the casing, and means for spring ing said plate forwardly past said orifices into engagement with the end of the casing.

In testimony whereof I hereuntoafiix my signature in the presence of two witnesses. HENRY EWVGLDT. Witnesses: PETER J. A. Summer,
