JOHN W. STANTON, OF NEW YORK, N. Y. ASSIGNORTO THE FIRE EXTIN- GUISHER MANUFACTURING COMPANY, OF SAME PLACE.

FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 223,402, dated January 6, 1880.

Application filed September 22, 1879.

To all whom it may concern.-

Be it known that 1, J OHN W. STANTON, of the city of New York, in the county and State it of New York, have invented certain new and useful Improvements in Fire-Extinguishers,

of which the following is a specification.

My improvements relateto that kind of portable fire-extinguishers in which a handpump is employed to throw water or other :0 liquid from a closed vessel upon a fire. Such vessels are provided with a vent for the free entrance of air when the pump is in use, so as to admit of the free and easy working of the pump, and such vent is usually provided with a cap or plug for closing the same when the extinguisher is not in use.

My invention consists in the combination, with the vent of a fire-extinguisher, of a hosepipe and a nozzle secured to said hosepipe and fitted to said vent, whereby when the extinguisher is not in use the vent is closed by inserting the nozzle therein or applying it thereto.

The invention also consists in a hose-nozzle of novel construction, whereby provision is aiforded for throwing either a stream or a spray.

In the accompanying drawings, Figure 1 represents a side elevation of an extinguisher 3o embodying my improvements, the nozzle being insertedin the vent-hole. Fig. 2 is a similar view, showing the extinguisher as em ployed to act upon a fire, the vent-hole being opened; and Fig. 3 is a detail view illustrat- 3 5 ing the manner of using my nozzle.

Similar letters of reference designate corresponding parts in all the figures.

A designates the vessel or chamber of the fire-extinguisher in which the water or other 4o liquid is contained, and B apump of ordinary construction for discharging the contents of said vessel or chamber.

C designates apiece of hose eXtendin g from the said pump and serving as a discharge therefor, and D designates a nozzle at the end thereof.

When it is desired to work the extinguisher,

the pump B is operated, and the liquid in the chamber is drawn up and forced out of the discharge-hose C and nozzleD upon the fire.

In order to permit the liquid to be drawn freely from the chamber or vessel, and to prevent the latter from being collapsed, I have represented a vent, a, arranged at the top of the vessel A, and the nozzle D corresponds in size and is fitted to the said vent, so as to form a stopper therefor.

In order that the nozzle shall fit tightly in said vent, the hole thereof is preferably made tapering or conical, and the tip b of the noz- 6o zle is correspondingly tapered, and, if desired, a ground joint ma be made between the two.

The nozzle might, if desirable, be provided with a mouth-piece fitting outside the vent in:

stead of inside, as hererepresented.

Many advantages result from forming the nozzle so as to serve as a stopper for the venthole, in addition to dispensing with a separate. stopper therefor. When so constructed the ventthimble acts as a protector or keeper for the nozzle and renders it impossible to use the apparatus without removing the vent-stopper, and therefore there is no such liability to collapse the vessel or chamber as there has been in "other extinguishers.

It is also obvious that when the nozzle is inserted in the vent the pump may be tried, to ascertain if it is in working order, without removing the nozzle or spilling and wasting the fire-extin guishin g liquid.

The nozzle D, as represented particularly in Fig. 3, is shown as beveled or slanted at the tip, so as to cut away a portion of the opening through it. When the nozzle is. so 0011- 8 structedit may be used for throwing a solid stream, as represented in Fig. 2; or by placing the thumb or finger upon the beveled end, as clearly illustrated in Fig. 3, the stream of liquid may be scattered and sprayed. The 0 character of the stream may be varied at will by slightly moving the position of the thumb. What I claim as my invention, and desire to secure by Letters Patent, is

, 1. The combination, with the vent of a fire- 5 extinguisher, of a hose-pipe and a nozzlese cured tosaid hose-pipe and fiLted to the said 3. A hose-nozzle having; one side of its tip Vent, substantially as and for the purpose beveled orslanted,substantiallyas and for the 10 specified. purpose specified.

2. The combination in a fire-extinguisher with a pump and a vent, of a discharge-hose JOHN STANTON for said pump provided with a nozzle which Witnesses: is fitted to said vent, substantially'as and for HENRY '1. BROWN, the purpose specified. FREDK. HAYNES.
