Patented Jan. 16, 1951 Elmer Prout, La Canada, Calif., assigner to Akron Brass Mfg. Company, Inc., Wooster, Ohio, a corporation of Ohio Application March 16, 1948, Serial No. 15,160

This invention relates broadly to nozzles, and, more specically, to improvements in nozzles of the type employed. in fire-fighting equipment.

Modern fire-'fighting technique relies on a special nozzle known as a fog nozzle to extinguish res, especially those of eiland gasoline origin. In some cases, however, the re is best controlled and put out by the old standard technique of playing a straight stream of Water on the conflagrati-on, which is based on the ram head principle.

Fires are generally complex in nature, requiring more than one type of stream to be used in abati-ng them. Thus, it is an object of this invention to provide a combination nozzle which will deliver a straight stream of water or a fos spray at the instantaneous control of the operator.

It is a further object of this invention to provide a combination straight stream and fog nozzle with an improved valve seal System so that a complete switch from fog to straight stream, and vice versa, may be made instantaneously'and without any leakage, thus giving the greatest possible efiiciency to the type of stream employed by the operator.

Another object of the invention is to provide a nozzle which is constructed to direct the flow of water through a passageway that is designed to produce a columnar stream, or through a second passageway that is designed to produce a finely divided spray or fog.

Another object of the invention is to provide a valve that will effectively seal either or both of the passageways in the nozzle when the valve is adjusted to eiectthe closure thereof.

Another object of the invention is to provide a nozzle which is designed to facilitate the ready renewal of the wear parts and Water delivery tips.

Further objects oi the invention reside in the provision of a nozzle that is light in weight, sturdy of structure, economic of manufacture, and adapted for manipulation with ease and dispatch.

Other objects more or less ancillary to the foregoing, and the manner in which all the various objects are realized, will appear in the following description, which, considered in connection with the kaccompanying drawings, sets forth the preferred embodiment of the invention.

Referring te the drawings:

Fig. 1 is a side elevational view of the improved nozzle;

fFig. 2 is a longitudinal sectional view thereof;

Fig. 3 is a similar section illustrating the valve i in anpactuated position; p

2 Claims. 1 (Cl. -299--141) Fig. 4 is a transverse sectional view, the section being taken on a plane indicated by the line '4 4 in- Fig. 3;

Figf is a longitudinalVse/ctional view of a modified form of the nozzle illustrated in Figs. 1 to 4;

Fig. 6 is a similar sectional View thereof shown in an actuated'position; and

Fig. 7 is a similarv sectional view shown in a further `actuated position.

Referring first to Fig. 2, the nozzle comprises generally a housing It having a bore II in the central portion thereof', a pair of passageways I2 and I3, parallel therewith, andterminating in bosses I4 and I 5 in the outer end of the housing, nozzle tips I6 and I1 threaded thereon and a valve plunger I8 mounted for axial translation Within the bore I I.

In detail, the valve plunger comprises a cylindrical body i9 machined `for snug sliding engagement within the bore il and formed with a helical groove 20 in the inner end thereof for the reception of a roller 2I (Fig. 4) supported on a screw 22 mounted in the housing Ill. The outer end of the plunger is bored to d'ene a channel C constituting the inlet for the nozzle, and the throat 23 thereof is threaded and counter-bored for the reception of a hose coupling and gasket 24. The free `end of the plunger is diametrically enlarged and provided with lugs 25 to accommodate rotative adjustments of the housing relative to the plunger. The inner end of the wall d'ening the channel C is cross-drilled to provide a plurality of ports 26 which are disposed for registration With an opening leading to the passageway I3 (Fig. 3) when the valve is adjusted to bring the roller 2l into engagement with the inner end of the groove 20. The ports 26 are closed by the wall defining the bore II when the valve is adjusted to bring the roller into abutting engagement with the outer end of the groove. The housing is provided with indicia (the word Fog as indicated in Fig.l l) to facilitate registration of the ports with the opening to the passageway I2 when the valve is adjusted to bring such marking into alignment with an arrow 21 on the enlarged end of the valve plunger I8. The bore II is formed with a groove 28 intermediate the openings to the passageways I2 and I3 for the reception of a soft rubber torus or socalled O-ring 29, and similar grooves 30 and 3l for like sealing elements are provided adjacent 'the opposed sides of the openings. A fourth groove 32 having an O-ring therein is provided in the bore in spaced relation with the inner .edge or `the groove 30. The web .deignin the end wall 33 of the bore II is drilled to provide a vent 34 for the escapement of air entrapped between the end wall 33 and the end of the plunger.

The fog nozzle comprises a thimble 35 tapped for engagement with the threaded boss I4 and counter-bored for the reception of a gasket 36. The outer face of the end wall of the thimble is formed with a conical recess 3'I having minute openings 38 therein which are drilled in normal relation to the inclined wall and arranged in opposition to each other so that the streams emitted therethrough will merge in impinged relation and form a finely divided spray. The inner face of the end wall of the thimble is of complemental configuration and further formed l with a circumambient wall 39 having trans-axial holes 40 therein which are disposed in radial .engagement with the threaded boss I and counter-bored to support a gasket 46. The body of the tip is bored throughout its length, preferably with a tapered passageway which merges with an outer cylindrical bore Il?.

Although the valve plunger is illustrated and described herein as being formed with a single row of ports 26, it will be understood that a greater number thereof may be used and that the invention contemplates such modification. For example, the plunger 50 may, if desired, be formed with a group of passageway means such as additional rows of ports 5S and 57 (Fig. 7) disposed for registration with the openings to the passageways I2 and I3 so that a straight or columnar stream of water and a fog may be delivered simultaneously by the nozzle. The single row of ports 58 is spaced from the passageway means 55 and 51 by a. distance greater than the axial terminal spacing of said body Vcanals I2 and I3 so that the water may be delivered to the passageway I2 (Fig. 5) while the other ports are blocked, or delivered to the passageway I3 (Fig. 6) when the ports 56 and 51 are closed.

The invention also comprehends the addition of a greater number of passageways similar to the conduits i2 and I3 and complemental rows of valve ports therefor, so that one or more straight streams, or one or more fog jets, may be simultaneously operated in any desired combination.

Although the foregoing description is necessarily of a detailed character, in order that the invention may be completely set forth, it is to be understood that the specific terminology is not intended to be restrictive or conning, and that various rearrangements of parts and modiiications of detail may be resorted to without departing from the scope or spirit of the invention as herein claimed.

I claim:

1. A nozzle assembly comprising a body having an axial bore extending from one end thereof, a pair of bosses extending from the other end of the body, canals in said bosses and body communicating at their inner ends with axially -spaced ports leading to said bore, nozzle tips mounted on said bosses, a sleeve valve in said bore, said sleeve valve having rst passageway means of an axial extent less than the axial spacing of said body ports and secon'd passageway means of an axial extent substantially equal to the axial spacing of said body ports, said first and second passageway means being axially spaced by a distance greater than the axial spacing of said body ports, and helical cam means formed on said sleeve valve and body so that relative rotation thereof axially and successively advances said body relative to said sleeve, from a terminal position wherein said rst passageway means is aligned with one of said body ports, to an intermediate position wherein said rst passageway means is aligned with the other of said body ports, and to a second terminal position wherein said second passageway means is aligned with both of said body ports.

2. A nozzle assembly comprising a body having an axial bore extending from one end'thereof, a pair of bosses extending from the other end of the body, canals in said bosses and body communicating at their inner ends with axially spaced ports leading to said bore, nozzle tips mounted on said bosses, a valve plug axially slidable in said bore, said valve plug having generally axial conduit means formed therein and arranged for communication with a source of fluid under pressure, said valve plug having iirst passageway means leading from said conduit means to the periphery of said plug, the axial extent of said iirst passageway means at the plug surface being less than the axial spacing of said body ports, said valve plug having second passageway means leading from said conduit means to the periphery of said valve plug, the axial extent of said second passageway means at the plug periphery being substantially equal to the axial spacing of said body ports, said first and second passageway means being axially spaced along the plug periphery by a distance greater than the axial spacing of said body ports, and means to cause relative axial motion of said valve plug and body from a terminal position wherein said rst passageway means and one of said body ports are aligned, to an intermediate position wherein said rst passageway means and the other o1 said body ports are aligned, and to a second terminal position wherein said second passageway means and both of said body ports are aligned.
