IMPROVEMENT IN FIRE-EXTINGUISHERSQ Specification forming part of Letters Patent No. 168,720, dated ctober 11, 18'75; application filed July 22, 1875.

To all whom it may concern:

Be it known that I, BENJAMIN F. CLEMIN- SHAW, of Troy, in the county of Rensselaer and in the State of New York, have invented certain new and useful Improvements in Fire- Extiuguishers; and dohereby declare that the following is a full, clear, and exact description thereof, reference being had to the accom- *panying drawings, and to the letters of referr hinging the acid-bottle thereto in such a manner that its mouth will he closed by the gravity of the bottle when the extinguisher is not in use, and will automatically free itself from the valve and empty its contents when the ex tinguisher is reversed, all as more fully here inafter set forth.

The figure in the drawings represents a sectional view of the entire apparatus, showing the same when not in use.

A represents the usual soda chamber or cy]- inder, having the usual plug O, with stopcock a and exit-hose D. The top of this cyl inder has a screw-opening, into which the cap or plug E is screwed Attached to the under central part of this cap is an inclined plate, Gr, which is provided with an under coverng of leather, rubber, or other suitable material, the two forming a valve to close the open end or mouth of the acid-bottle. Hinged to ears extendn g from the bottom of the plug, near the valve Gr, is a frame, H, into which the acidbottle K is placed. When this bottle is filled the weight of the same will cause it to press the mouth of the bottle close against the valve in the manner shown in the drawings, making a perfectly air-tight joint. When the cylinder is reversed for us e the bottle will free itself from the valve and empty its contents into the soda-chamber, and form the gas for extinguishing fires, in the usual manner.

By this construction the apparatus is easily, operated, and the parts can be quickly charged for use. The plug E, valve D, and frame E[, with 'bottle K, are all connected, and, by simply unscrewing the plug, they are all extracted together from the cylinder, so that the .filling can he accomplished and the parts replaced at once.

I do not claim the stopper having a flaring rim attached thereto, as such is not my invention.

What I claim is The nclined stationary valve Gr and the frame H, hinged to the cap E, and containing the acid-bottle K, in combination with the chamber A, all substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of July, 1875.
