RUSSELL A. BALLOU, OF NEWTON, MASSACHUSETTS, ASSIGNOR TO THE CHEMICAL HAND FIRE EXTINGUISHER COMPANY,A OF PORTLAND, ME.

FAUCET FOR CHEMICAL FIRE-EXTINGUISHERS.

SPECIFICATION forming part of Letters Patent No. 348,096I dated August 24, 1886*.

Application filed Noxember 23, 1885.

To all whom it may concern:

Be it known that I, RUssnLL A. BALLoU, of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Faucets, of which the following is a specication.

My invention relates to faucets, and more particularly to the class intended for use in connection with fire-extinguishing apparatus; and my invention consists in improvements in such faucets, al1 as hereinafter described, and subsequently pointed out in the claim.

Of the accompanying` drawings, forming a part of this specification, Figure 1 represents a sectional view of my improved faucet and cover, showing the faucet closed. Fig. 2 represents a top view of the faucet and cover.

The same letters of reference indicate the same parts in all the figures.

My improvement is mainly intended for a chemical fire extinguishing apparatus like that shown in my pending application for Letters Patent of the United States, filed September28, 1885, Serial No. 17 8,347 said apparat-us consisting of a receptacle adapted to contain liquid chemicals, a glass bottle in said receptacle adapted to contain another chemical or chemicals, and means for breaking said bottle to liberate the contents and mix said chemicals, thus generating gases and creating pressure in the receptacle,whieh forces the gases and liquid through an outlet or nozzle controlled by a faucet.

In carrying out my invention I secure the casing c of said faucet rigidlyto the cap or the cover la of said receptacle, preferably by casting them in one piece, the cover having a threaded flange, 7c', adapted to be secured to a thread cut on the receptacle. The faucet has a branch, b, extending into the interior of the receptacle, said branch being preferably supplemented by a pipe extending nearly to the bottom of said receptacle.

d represents the outlet-passage of the faucetcasing, extending through the cover k and preferably terminating in a short nozzle, cl, on the outside of the cover.

when turned away from said position. To the lower end of the plug is attached an arm, g, which, when the faucet is closed, acts to support aspring-plunger, l1, in aholder, i, formed 5 5V with or attached to the faucet-casing c, said plunger being held by the arm g when the 'faucet is closed, and released so as to cause the breakage of the glass bottle in the receptacle when the faucet is opened, as shown in my 6o above-named application and in another application filed concurrently with this. The socket formed in the casing c for the plug 2 is extended through the top of the cover, so that the plug can be inserted and removed through 6 5 the top of the cover.

a represents a plate fitted to slide on the top of the cover k, and secured thereto by a screw,

0, inserted in the cover through a slot, p, 1n said plate. The plate has a keyhole-shaped 7o slot, i, through which the stem s of the plug passes. Said stem has two parallel sides at the point where it passes through the slot i', and the narrower portion of said slot fits closely against said parallel sides and pre- 7 5 vents the stem from turning when the plate a is at one end of its movement.

W'hen the plate is moved so as to cause the wider end of the slot r to inclose the stem s, said stem is released and may be freely ro- 8C tated. When the stem is locked, as above described, the plug 2 is in position to close the faucet and hold the plunger lz.. It will be seen that the faucet and cover thus united'so as to form one part, enables the faucet with its discharge-nozzle to be readily applied to and removed from the receptacle, while the extension` of the plug-socket and plug through the top of the cover enables the plug to be readily removed for cleansing or repairs.

This improvement is not limited to fire-exti nguishing apparatus, but the faucet with the cover or cap may be applied to other receptacles with which faucets are used.

In another pending application filed September 28, 1885, No. 178,347, I have shown a faucet-casing formed on a cover and provided with a plug, and with an inlet-passage formed to extend into the vessel to which the coverbelongs, and with an outlet-passage passing 10o through the cover. i

My present invention differs from that set forth in my above-named application, in that a locking device isprovided inthe present instance to hold the faucet-plug closed. I do not therefore here claim the cover having the casing and faucet-plug, excepting as improved in the particularspecified.

I elaim- The combined cover or cap and faucet, consistiug of the cover having the faucet-casing formed integral therewith, the said cover being provided with a screw threaded flange adapted to engage with and be screwed upon the screwtl1readed portion of the receptacle to which it is to be applied, a plug-socket extending through the casing and the top of the receptacle, a branch passage formed in the casing and communicating with the` interior of the receptacle and with the plug, and an outlet-passage formed in the casing or cover 'com municating with the plug and the exterior RUSSELL A.
