CHEMICAL FIRE-EXTlNGUISH-ER.

SPECIFICATION forming part of Letters Patent N o. 409,037, dated August 13, 1889.

Application lcd May 15, 1889. Serial No. 310,863. (No model.) Patented in England December 20, 1887, No. 17,487; in France September 21, 1888, No. 193,120, and in Belgium September 22, 1888,1\To. 83,358.

To all whom, .it may concern:

Be it known that I, JAMES HASLAM, chemical fire-engine n'lamifacturer, ot Bury Road, Tonge, near Bolton, in the county ofvLancaster, England, have invented new and useful Improvements in Chemical Fire-Extinguishing Apparatus, (for which I have obtained a patent in Great Britain, No. 17,487, dated December 20,1887; in France, No.193,120, dated September 2l, 1888, and in Belgium, No. 83,858, dated September 22, 1888,) of which the following' is a specification.

This invention relates to improvements in what are known as chemical lire-extinguishers, in which a vessel containing water in solution with a carbonate or alkaline compound and a bottle containing acid are employed; and it consists in providing means for effectually and readily charging the apparatus and' breaking the said bottle, so as to mix the acid with the water.

Figure 1 is a sectional elevation of my improved chemical nre-extinguisher. Fig. 2 is a partly-enlarged sectional elevation of the nozzle and hinged cap or cover. Fig. 8 is a plan of Fig. 2, and Fig. et is an outside View of Va light portable iire-extinguisher with my improved cap and attachments for breaking the acidbottle applied thereto.

In all the lfigures the same letters are used to indicate corresponding parts.

A is the case of the extinguisher, which can be made of any suitable material-such as copper, tinned iron, and others. On the end of the case A is secured the metallic nozzle B,

to which is attached the hinged 'cap or cover D by the pin C. The cap or cover D is provided with the cavity X, to receive the ring Z, which may be of india-rubber, or other substance most benecial for the purpose. The ring Z is provided with the hole or vent Q, to allow vapor or pressure to escape as it is generated through the heat of the room or other place the extinguisher may be located in, also to prevent the liquid being forced up the pipe -R. Immediately the acid-bottle E is broken the pressure generated thereby forces the disk H against the under side of the ring Z and closes the hole Q, which causes all the liquid to be forced out of the extinguisher through the nozzle S on the end of t-he pipe B. On the hinged cap or coverD is mounted the swiveling handle lV, bythe ferrule or hollow center Y, the latter being secured by the ends being bent over, as shown, or in any other convenient manner. To the swiveling handle XV is attached the lip V, which slides under the bayonet or other projection T on the outside of the nozzle B when the hinged cap or cover D-is closed over the nozzle B, as shown in Figs. 2 and 3. closed over the nozzle B, the ring Z is pressed onto the outer edge O, by which a perfectly tight joint is made, pressure being imparted by the action of the lip V on the swiveling handle XV in sliding under the bayonet projection T. Vhen it is necessary to raise the hinged cap or coverD,the handle W is swiveled sidewise, as in dotted lines in Fig. 3, thereby removing the lip V from under the projection T.

E is the acid-bottle, which sits on the con caved cross-bar F, attached to the case A.

The acid-bottle E is made with the indents G, to facilitate handling when passing it through the nozzle B to the cross-bar F.

For the purpose of breaking the acid-bottle E, I mount the ring Z on the spindle G With the disk H. The ring Z is pressed tightly on the spindle G, by which the latter is held clear of the bottle E bythe elasticity of the ring Z. Over the spindle G is mounted the ferrule 1, resting on the top side of the ring Z. On the top end of the ferrule I is mounted the knob J, screwed to the spindle G.

The acid-bottle E is broken by striking the knob J, which forces the spindle G and disk H onto the top side of the bottle E. Immediately the knob J is struck and the pressure is removed therefrom it assumes its normal position by the elasticity of the ring Z.

The extinguisher-case A is provided with the outlet-pipe R, perforated at the bottom end, and through which the liquid is forced when the bottle E has been broken.

The case A of the light portable iire-extinlVhen the hinged cap or cover D is 5 secure by Letters Patent, is-

1. In a chemical 'fire-extinguisher, the coinbination, with an alkali-vessel containing an acid-bottle in its upper portion, of a cover having a central orifice and a cavity in its Io under side, an elastic ring secured in said cavity, a tube extending through the orifice in the cover and resting on the elastic ring, and a spindle extending through the tube and through the ring and carrying a disk below 15 the latter, substantially as described.

2. A chemical fire-extinguisher consisting of an alkali-vcssel containing an acid-bottle,

a nozzle arranged on the vessel and having a lateral projection, a cover hinged to the nozzle and having a central orifice and a cavity in its under sid e, an elastic ring arranged in said cavity, a ferrule arranged in the central oritice of the cover, a tube extending through the ferrule, a spindle passing through the tube and ring and having a disk below the latter, and ahandle pivoted on the ferrnle and having a lip to engage the projection on the nozzle, substantially as described.

In testimony whereof I alix my signature in presence of two Witnesses.

JAMES IIASLAM. Vitnesses:
