THOMAS F. HANDLY, OF ALLEGHENY, PENNSYLVANIA.

FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 564,615, dated July 28, 1896.

Application filed .Tuly 27, 1895. Serial No. 557,346. (No model.) l

To all whom it may concern.'

Be it known that I, THOMAS F. HANDLY, a citizen of the United States of America, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Fire-Extinguishers, of which the following is a specication, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in iireextinguishers, the object of which is to supply a chemical compound to the water while it is flowing through a hose-nozzle toward the dischargeopening, and in providing novel means for increasing the iow of water after the chemical has been absorbed.

A further object of the invention is to make the parts strong, durable and efcient, as well as comparatively inexpensive to produce and sustain.

A further object is to provide a chemicallycharged nozzle having a supplemental open end which is designed to be broken when the chemical is absorbed or when it is desired to have an-increased volume of water.

With these and other objects in view the invention resides in the novel details of construction, arrangement, and combination of parts to be hereinafter more fully set forth and specifically claimed.

In describing the inventionl in detail, reference is had to the accompanying drawings, forming a part of this specication, wherein like numerals denote corresponding parts in the several views, in which Figure l is a View in side elevation. Fig. 2 is a central longitudinal sectional view of the same. Fig. 3 is a similar view of a modified construction. Fig. 4 is a similar view of a further modification.

In the drawings, l 2 denote the sections of a nozzle having flared or cup-like connecting portions forming a casing or receptacle 3, said sections being disconnected when it is desired to renew the charge or gain access t0 the interior of the nozzle. Angular lugs 4 are arranged on the casing and are used for turning the sections when joining or discon necting them. The lugs are so arranged as to form handles, which can be advantageously used for supporting and manipulating the nozzle. 5 is a supplemental nozzle, screwthreaded or otherwise joined to the main portion. The bore or aperture of this supplemental nozzle is smaller than that of the nozzle proper, and is adapted to be used in conthe usefulness of a charge the stream is reduced bythe supplemental nozzle, but when the chemical is exhausted, or when it appears advisable to deliver a larger stream, the supplemental nozzle is broken oi, for in making the same I reduce the wall, as at 7, and by forming it of a brittle metal a blow on the ground or against an object will result in breaking it, when the stream will be increased to the size of the bore of the nozzle proper, as will be apparent.

Interiorly of the nozzle I arrange a chemical cartridge. As shown in Fig. 2, there is a cylindrical central opening 8, corresponding to the bore of the nozzle, vsurrounded by a chemical powder, which .is taken up by the water in its course therethrough.

In Fig. 3 I show a gauze casing 9, supported by the arms 9a, with a waterway between the casing and wall of the nozzle. The casing in this instance contains the chemical, and the water surrounding it is charged as it flows.

FigA illustrates a cigar-shaped casing supported by the spiders 10, 10', and 1l, with a waterway between the casing and nozzle for the purpose explained.

In applying the invention to practical use I employ a powdered chemical, with which the cartridge is charged, although it will be found desirable at times to :mold the compound in a predetermined solid shape and provide it with a central opening provided with a wire-gauze casing similar to that shown in Fig. 2. This last form, as Well as all others, I provide with a gelatin coating, impervious to dampness or other atmospheric conditions which might cause a deterioration of the chemical properties. l

It is well known that the gaseous charged IOO liquid used at the present day gives 0E a portion of its gas while passing through the air,V

thereby impairing to a great extent its efflciency. It is my object to charge the water With a chemical which Will produce gas when It is aWell-known and established fact that in cases Where the chem-ical forms a solution 1 With the Water and comes in contact constantly with the receptacle the tendency will be that in course of time the receptacle and connections Will become aected by the cheml lon the .sections of the vnozzle :so formed as to ical action.

In View of the foregoing it Will be obvious that this invention may be applied and the spirit thereof carried out in a plurality of Ways and that the proportions and other details Yof construction may be varied Without departing from the spirit of my invention.

Having fully described my invention, what I claim as new, and .desire to secure VbyLetters Paten-t, isf.-

1. A nozzle formed to produce a chamber, a chemical charge, .coatedto exclude moisture, arranged therein :to .come in contact with the Water and a supplemental nozzle having an open end arranged on .the nozzle and-ad apted to be broken, for the purpose described.

2. A Ynozzle formed to produce a chamber,

a chemical charge arranged therein to come in con-tact with the Water, a supplemental nozzle having an open end and arranged on the nozzle and having the Walls reduced to facilitate the fracture, as and for the purpose described.

3. A nozzle formed to produce a chamber, a chemical charge arranged therein to come in contact With the Water and a supplemental nozzle having an open end arranged on the nozzle and adapted to be broken and lugs produce a handle when the sections are screwed together.

4. A nre-extinguisher provided with a noz- Zle chemically charged, anda supplemental open end Vdesigned to :be broken, for the purpose described.

5. A nozzle formed in sections,angu`larlugs arranged on the sections for turning .the sa-me and forming handles when the sections are screwed together, for .the purpose described.

In testimony whereof Iaix my signature in presence of two Witnesses.
