SPECIFICATION forming part of Letters Patent No. 695,847, dated March 18, 1902.

Application filed January 12, 1901. Serial No. 43,068. (No model.)

T0 all whom, it may concern:

Be it known that we, RANDALL T. V AN VAL- KENBURG,1esiding at Newcastle,in the county of Lawrence and State of Pennsylvania, and CHARLES J VAN VALKENBURG, residing at Manchester, in the county of Vashtenaw and State of Michigan, citizens of the United States, have invented a new and useful Fire- Extinguisher, of which the following is a speciication.

This invention relates to fire-extinguishers; and the objectin View is to provide what might be termed a selfacting7 chemical fire-extinguisher.

In its preferred form the invention contemplates a frangible receptacle or vessel containing a tire-extinguishing agent which may be either of liquid or solid or granular form, and in connection with said vessel we employ an explosive compound having adjacent thereto an igniter composed of material which is rendered combustible at a certain temperature, thus adapting the igniter when the temperature reaches a certain point to set off the explosive compound and cause a sudden and Violent breakage ot' the vessel, which results in scattering the fire extinguishing agent through a considerable area, whereupon it acts to smother the iames.

A point to be borne in mind as deiining and strongly dierentiating this invention from the art is that the igniter is rendered operative by transmitted heat or, in other words, air heated to a high temperature, as opposed to a nre-extinguisher requiring direct heat or contact with the igniter by a flame before it will operate. The advantage of the igniter of the present invention will be obvious, for Whereas with fire-extinguishers of the character last dened a tire could exist in a room or building and gain such headway as to become disastrous without effecting such extinguisher so long as the flame did not contact with it, while with the extinguisher of the present invention should the temperature of a room reach a point bearable by human beings but produced by a iire the extinguisher will be operative. It is to be understood, therefore, that the statement to the effeet that the igniter is rendered operative by transmitted heat is to be defined as meaning that actual contact by the igniter of a ame is not necessary to its proper operation.

In carrying ont the present invention under the preferred embodiment thereof various details of construction and arrangement of the contributory elements are resorted to, the nature of which will appear more fully in the course of the subjoined description and the novel features of which will be pointed out in the claims.

In the accompanying drawings, Figure l is a central longitudinal section through a lireeXtinguisher com plete, constructed in accordance with the present invention. Fig. 2 is a bottom plan View of the same. Fig. 3 is a fragmentary section similar to Fig. l, showing a modified construction of Vessel or receptacle.

Similar numerals of reference designate corresponding parts in all figures of the drawings.

In carrying out the present invention we employ a vessel or receptacle l, which is preferably frangible and composed of some such material as glass. It is preferred to form this vessel with a neck or mouth 2, by means of which it may be iilled with the re-extinguish ing agent. The tire-extinguishing agent may consist ofanywell-known chemicalcompound for the purpose and may be either in liquid form, as indicated at 3 in Fig. 1, or it may be in dry, solid, or granular form, as shown at et in Fig. 3. Y

The frangible vessel l is provided with an elevated or false bottom 5 of the same matevrial as the body of the vessel and having its central portion offset inwardly, as illustrated in Figs. 1 and 3. Communicating centrally with the bottom 5 is a holder @for the explosive compound, which is preferably supplied in the form of a cartridge (indicated at 7) and provided with a fuse 8. The cartridge holder orchamber 6 forms an inward eXtension of the bottom 5, being preferably formed integral therewith and being thereby also frangible. As the holder 6 extends inward from the bottom 5, it will be seen that it is comprised wholly within the plane of the vessel l and is not subject to accidental frac- IOO ture. It will further be noted th-at the side wall or main body ot' the vessel 1 is extended below the bottom 5 to form a surrounding continuous ange 9, and this ange, taken in connection with the bottom 5, forms an ignition-chamber in which the igniter is placed and sealed by means of a closure 10, which may consist of a plate corresponding in shape and size to the bottom of the vessel.

The explosive cartridge 7 may be of any desired character; but it is preferred to employ one having a projecting fuse 8, which will extend into the ignition-chamber, so as to come in contact with the igniting material. The igniter consists, preferably, of a combination of guncotton and Celluloid, and the said elements are preferably arranged in layers, 11 designating the layers of guncotton, and 12 thev intervening layers of Celluloid. These layers are arranged so as to surround the fuse 8 and fill the ignition-chamber.

As is well known, guncotton will ignite or be rendered combustible at a temperature of 180O Fahrenheit, while celluloid will ignite at a temperature of 200 Fahrenheit. It h`as,how ever, been ascertained by actual experiment that where celluloid and guncotton are combined they will ignite ata temperature of 160 Fahrenheit, and this action and result is promoted by sprinkling sulfurin powdered form upon and into the guncotton.

Where the fire-extinguishing` agent is used in dry form, as indicated in Fig. 3, the chainber or holder G may be dispensed with and the cartridge of explosive compound may be placed directly in the extinguishing agent and within the body of the vessel,'in which case a small opening 13 will be provided in the bottom 5 to enable the fuse 8 to pass therethrough into the ignition-chamber.

In order to carry and suspend the fire-extinguisher, we employ a bail-shaped carrying-frame 14, which preferably consists of a strip or band of metal, preferably in the form of Wire, as shown in Figs. 1 and 2, the central portion of said strip or wire being twisted upon itself, as at 15, and fashioned into a carrying or suspending loop 16. The opposite arms of the frame are passed through openings 17 in the opposite ends of a bar or 'yoke 18, which extends diametrically across the bottom of the vessel, and the terminals of the wire are then bent inward and clenched against the body of the yoke or, bar 18, as shown at 19, while the extremities are swaged inward, as shown at 20, and partially embedded in the lower surface of said yoke. Prior lo the operation just described, however, a stopper 2l is insertedin the neck of the vessel, and the central portion of the carrying-frame is brought to bear firmly against the stopper, so that after the terminals of the frame have been clenched upon the yoke or base-bar 18 the stopper is prevented from becoming displaced and the carrying-frame is held centrally of the vessel. The vessel may be suspended at any desired place in a room or building, or it may be placed upon the floor at some point where it will be out of the way.

The operation of the fire-extinguisher is as follows: As soon as the fire raises the temperature of the room or lbuilding in which the extinguisher yis contained to a certain point the igniter acts spontaneously and sets fire to the fuse 8. This in turn explodes the compound or cartridge and causes a sudden and violent breakage of the frangible vessel, with the result that the fire-extinguishing agent or compound is scattered throughout a considerable area. By providing the vessel with a frangible bottom as well as main body portion the vessel is completelyv demolished, and in the construction in which the cartridge chamber or holder 6 is employed said holder is at the same time demolished. Prior vto the destruction of the vessel, how ever, the several agents or compounds contained therein are held separated and prevented from coinmingling. It will thus be seen that the fire-extinguisher hereinabove described is entirely automatic in action and does not require the presence of a person to remove the stopper or to break the vessel by striking or throwing the same violently against a wall, iioor, or other surface. Any suitable explosive cartridge or torpedo may be employed for obtaining the desired eect and combined with the other elements named.

In addition to breaking the vessel and scattering the contents thereof the cartridge or explosive compound also produces va sharp loud report, and thus gives an audible alarm or signal to the occupants of the building.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described fire-extinguisher will be readily apparent to vthose skilled in the art without further description, and it will be understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
