FIRE-STREAM DIS'IORTEB.

Specification of Letters Patent.

Patented M nse, 1915.

Application filed May 27, 1914. Serial N 0. 841,271.

To all 2071 cm it may concern Be it known that I, HUBERT J. HorKrNs, a citizen of the United States, residlng 1n the city and county of San Francisco and State of California, have invented new and useful Improvements in Fire-Stream Distorters, of which the following 1s a specification.

This invention relates to a fire stream d1storter or director. 7

- run at a moments notice, as the nozzle, when released, especially where high pressure is employed, 1s practicallv as destructive to -life and limb as a falling wall.

It is one of the objects of the present invention to provide a nozzle, which is so constructed that the water passing through the nozzle may be deflected or diverted through an annular discharge opening at a moments notice in such a manner as to render the nozzle absolutely harmless. The

firemen are thus free to drop the hose and run without danger of being struck by the nozzle. r

Another object of the invention is to provide means whereby a small portion of the water passing through the nozzle may be allowed to escape laterally in such a manner as to partly spray the men and at the same time throw out a stream of water in all directions between themen and the fire. A great advantage is thus gained,as the firemen are able to apply the water directly upon a fire instead of being obliged to stand at a great distance. i

Further objects will hereinafter appear. The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- 1 Figure 1 is a side elevation of the nozzle. Fig. 213 a central vertical section through same. Fig. 3 is a cross section on line mm, Fig. 1.

Referring to the drawings, 'A indicates the main casing of a fire hose nozzle; 2 the nozzle proper; and 3 the valve which may be adjusted and operated in any suitable manner. The inner end of the nozzle proper is provided with a seat 4: for the valve and an exterior annular flange 5which is grooved, as at 6, to receive a gasket 7. Formed integral with the flange 5, or connected to the same by ribs 8, is an exteriorly threaded section 9, and turnably mounted on said threaded section is an interiorly threaded, adjusting sleeve 10 which forms one part of a coupling hereinafter to be described.

Formed interior of the-main casing is an annular seat 10 which is adapted to form a connection betweenthe main VtllWE seat 4 and the casing, while the end of the cas ing engages with and seats upon the gasket 7. An interior pressure; chamber 1-1 is formed between the annular seat in the easing and the exterior ofthe casing and inlet ports 12 are provided to admit water into the pressure chamber. v

The main coupling, previously referred to, by which the nozzle proper is secured to the main casing is constructed as follows:

Formed exterior on the casing is a pair of

lugs

13 and 1 1, andladapted to project into engagement with the lug 13 is a projecting lug 15; lug 15 being secured upon the lower end of a coupling sleeve 16, upon which sleeve 10 is turnably mounted, and flanges 17 and 18 forming a coupling between the two members- T he contacting faces between the

lugs

13 and 15 are angularlv disposed, as indicated at-19. and adapted to be inserted between the other side of lug 1 5 and lug 14 is a block 20 which is carriedsbv a leaf spring 21, which in turn is secured, as at 22, upon the exterior of thecasing. The other side ofthe casing is similarly provided with a lug 13*, against which a lug 15 is adapted to contact. The block 20, together with't'he spring 21, is held in the locked position between the lugs 14and 15 by means of a ring-23 which is slida'bly to turn the adjusting sleeve 10 by such means as a spanner, wrench, or the, like.

This permits the nozzle to move outwardly,

1 with relation to the main casing, 21 sutlicient dlstance to permit the escape of a smallportion'of the water between the gasket 7 and the end of the casing. Anannular discharge is thus formed around the nozzle, which'will form a constant sprayor sheet of water in front of the firemen." The fireblock 20. This permits the spring 21 to lift the block out of engagement with the lugs 14: and 15 and will consequently permit the lug 15 to free itself, with relation to the lug 13, the same taking place on the opposite side of the casing. The nozzle thus released will immediately slide out upon the main casing until the main valve seat 4: closes upon the valve. The discharge of water through the nozzle is thus completely cut off and all the water is permitted "to escape through the annular opening thus formed and the nozzle is rendered entirely harmless and may be instantly dropped. The danger connected with the nozzles now in use is entirely eliminated and the firemen may run away without being in danger ,of the nozzle.

The pressure chamber, formed between the annular seat 10 and the-end of the casing, provides a means by which the nozzle can be moved outwardly upon the casing.

A nozzle constructed as here shown is simple in construction and as far as outward appearances are concerned is practically similar to the standard nozzles now employed. The releasing mechanism shown in connection with the nozzle coupling is very simple and may be quickly operated.

I wish it understood that various changes in form, proportions, and minor details of construction may be resorted to within the scope of the appended claims and that I do not wish to limit myself to the specific design and construction here shown.

, Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In combination with a nozzle having an'interior seat and a valve engageable with said seat, an annular flange projecting outwardly from the nozzle periphery and having a gasket on its under face, an annular seat at the base of the valve seat spaced from the gasketand surrounded the latter, a casing having a chamber the inner wall of which engages the annular seat and the outer wall ofwhich engages the gasket, the inner wall of the chamber having inlet ports, an eXteriorly threaded member connected to said nozzle, a sleeve threaded into engagement with the member, a coupling sleeve connected to the threaded sleeve, and means to releasably connect the coupling sleeve to the casing.

7 2. In combination with a nozzle having an interior seat, and a valve engageable with said seat, an annular flange projecting outwardly from the nozzle'periphery and having a gasket on its under face, an annular seat at the base of the valve seat spaced from the gasket and surrounded by the latter, a casing having a. chamber the inner wall of whichongages the annular seat and the outer wall of which engages the gasket, the inner wall of the chamber having inlet ports, an exteriorly threaded member connected to said nozzle, a sleeve threaded into engagement with the member, a coupling sleeve connected to the threaded sleeve, a pair of lugs on the casing having an angular space therebetween, an angular lug on the coupling sleeve receivable in the space between the pair of lugs and engaging one of the latter, a block receivable in the space between the pair of lugs and engaging the lug of the coupling sleeve and the other lug of the pair of lugs, fiat spring connecting the block to the casing, and a ring slidable on the casing and engaged over the spring to hold the latter and theblock in operative position.

3. In combination with a nozzle having an interior seat and a valve engageable in said seat, a flange projecting outwardly from the nozzle periphery, an inner seat on the nozzle, an outer seat on the flange, a casing having chamber the outer end of which is open and the side walls of which are engageable with said inner and outer seats, said chamber having communication on its inner side with the interior of the casing, and means to adjust the casing relative to said inner and outer seats.

4. In combination with a nozzle, and a valve to cut off the longitudinal discharge of water through the nozzle, a member cooperating with the nozzle to allow of lateral escape of water, said member slidably supporting the nozzle and rigidly supporting the valve, and releasable means to hold the nozzle against sliding movement, said releasable means upon release thereof allowing the nozzle to instantaneously move to a position to enable the valve to cut-ofi the longitudinal discharge of water.

5. In combination with a supporting member, a nozzle slidable on said member, a valve connected to said member to close the longitudinal discharge of the nozzle, said nozzle'and member having a lateral water discharge therebetween, and releasable means to hold the nozzle against sliding movement and which when released allows the nozzle to instantaneously move to a position to engage the valve and to open the lateral discharge.

6. In combination with a supporting memher, a nozzle slidable on said member, a valve connected to said member to close the longitudinal discharge of the nozzle, said nozzle and member having a lateral water discharge therebetween, and releasable means to hold the nozzle against sliding movement and which when released allows the nozzle to instantaneously move to a position to engage the valve and to open the lateral discharge, and means independent of the releasable means to allow the nozzle to be moved so as to allow of regular egress 10 of the water through the lateral discharge;
