- HAND FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 540,231, dated .T une 4, 1895.

Application filed February 1. 1895. serial no. 536,985. (No man.)

To all whom it may concern.-

Be it known that I, JAMES HENRY BYRNE, of the city of Toronto, in the county of York and Province of Ontario, Canada, have invented a certain new and useful Hand Fire- Extinguisher, of which the following is a specification.

The object of the invention is to provide a hand fire extinguisher so constructed as to prevent any loss of chemicals during the generation of the gas, as well as any liability to loss of the gas not taken up by the water, and which is capable of throwing a stream of gas-charged water over a Wide range, when inverted, and While retaining an approximately vertical position, and it consists, essentially, of .two cy1inders,`one located within the other, the smaller one designed to contain a liquid and having its neck closed by a breakable seal and being of such size as to leave a space between the two cylinders, a cone-shaped shelf (a section of which is perforated) applied to the ends of the two cylinders so as to form a third chamber to retain the carbonate of soda or other carbonate in position, breakable balls or vessels for containing acid, means for breaking the breakable balls and the breakable seal so as to admit the liquid tothe third chamber when the extinguisher is inverted, and to liberate the acid so as to combine with the carbonate, and a swivel-cock located in the outer cylinder outside the third chamber opposite to the perforated section thereof, and which is adapted to shut od the gas-charged liquid when the nozzle is turned parallel to the major axis of 'the section shown in Fig. 4.

Like letters of reference indicate corresponding parts in the various Iigures.

In Fig. 1-A, is the outer cylinder which is preferably shaped as indicated and made of metal. Y A

provided with a hole through which the plun-4 ger rod E, projects.

h, is a ring or ledge at the bottom of the outer cylinder, which preserves the inner cylinder in place within the outer one.

C, is a shelf or diaphragm, the shape of which is more particularly shown in Fig. 2, and which rests on the top of the inner cylinder B. Its top may be soldered, or otherwise secured to the upper part of the cylinder A. t

I, is a breakable seal, which is centrally located and is in the neck B of the inner cylinder B. It rests on the flange t', and may be further held; .in place by plaster of paris, or otherwise.

The diaphragm O, with the breakable seal I, and the cover Q, of the inner cylinder forms a third chamber D, in which are placed the carbonate of soda or other carbonates, as well as the acids contained in the breakable balls G, hereinafter referred to.

' c, shows perforations in the diaphragm O.

E, is a plunger rod, which passes, as already mentioned, through the screw cap` R, and is provided with the head e, and a break bar F. This break bar F, is sufficiently close to the breakable balls G, as to hold them and the saddle H, in place in the `slot d, when the hand fire extinguisher is inverted or turned upside down. The plunger rod E, also tits sufficiently close within the hole in the screw cap R, as to enable the break bar F, to perthe slot d, formed in the neck C. (See Fig. 2.)

h, shows heads formed on the arms h', to

ICO

prevent lateral motion and displacement of the saddle H, which is carried by the slotted neck 0'; and el', is a central ring through which the plunger rod E, may pass so as t0 break the breakable seal I J, is the liquid which is sealed in the inner cylinder B, and may be water or water-charged with brine or other compound, as may be desired. V

K, is a swivel cock which is specially adapted for use in this hand fire extinguisher so as to admit of a large range over which the gas-charged water may be discharged. It is situated in the upper part of the outer cylinder A, when in its normal position, as inv dicated in Fig. l, and is outside of the third chamber D, and immediately opposite to the perforations c, formed in the wall thereof. It is located here outside of the chamber in which the gas is first formed and is opposite to the perforations c, in order to avoid any undue escape of chemicals before combination or of gas before it has been taken up by the water or has reached the .position when the hand fire extinguisher is inverted in order to exert a pressure to expel the gas-charged water from the nozzle of the swivel cock when directed on the fire. The details of this swivel cock are shown in Figs. 4 and 5, in which L, is the discharge branch, and M, is an elbow formed thereon and at right angles thereto. This elbow is preferably of a conical form, and'has a central opening m, for the water.

n, is a water outlet at right angles to the central opening m, and is situated about half way down on the cone-shaped elbow M.

O, is a swivel joint which fits over the coneshaped elbow M, and is adapted to rotate thereon. From it is cut out a chamber 0, which chamber is designed to give a greater range for the discharge of the liquid by the swivel cock K.

P, is a water chamber formed integral with the swivel joint O, and communicates directly f with the chamber o, in the swivel joint O.

k, is a nozzle which is screwed within the water chamber?.

In Figs. l and 4, the swivel cock K, is shown in a position when the water is turned 0E. When the swivel cock K, is moved in the direction of the arrow head,and as soon as the wateroutlet n, comes opposite to one end of the chamber 0,'cut out of the swivel joint, the water immediately commences to discharge from the nozzlelc, and it continues so to discharge until the nozzle has been so turned around that. the other -end of the chamber 0 passes the mouth of the'water outlet fn.. This obviousl57 gives a wide range for the water either in an upward or downward direction, while'at the same time the hand fire extinguisher is kept in a vertical position.

The mode of yoperation of my device is as follows: The plunger rod E, being 'pushed or forced down by a blow on the'head e,`breaks thebreakable balls G, in which is contained tions c, in the wall of the diaphragm C, fills the chamber S, and circulatesround so as to enter the discharge branch L, of the swivel cock K. At the same time the gas and gascharged water rises inthe cylinder B. The pressure of the free gas on the top of the gaschargedl water, when the hand re extinguisher is in this inverted position, creates a pressure downward so as to expel the gascharged water with great force when the nozzle is turned on in the direction, as indicated by the arrow-head.

By my improved hand fire extinguisher, all possibility of escape of chemicals or of gas before it has become completely taken up by the water and before it has fulfilled its oftice of driving out from the hand iire extinguisher the gas-charged water, is obviated and no matter in what position my hand fire extinguisher may be held from the vertical, it is practically impossible that any free gas should escape from the nozzle, until all the liquid is discharged.

The form of swivel cock and my improvement therein are specially designed to obtain a wide range, as already stated, for the discharge of water over any fire without moving the hand fire extinguisher from its approximately vertical position.

What I claim as -my invention is l. In a hand fire extinguisher, the combination with two cylinders forming two chambers, of a partly perforated diaphragm forming a third chamber, a breakable seal closing one of said chambers and breakable balls or vessels contained in one of said chambers, means for breaking the balls and seal, and a Valve, substantially as described and for the purpose specified.
