COMBINATION NOZZLE I Filed May 4, 1956 2 T1 E I INVENTOR ATTO R N EY United States Patent COMBINATION NOZZLE Ignatius Nurkiewicz, Colts Neck, N. 1., assignor to Stop- Fire, Inc., Brooklyn, N. Y., a corporation of New York Application May 4, 1956, Serial No. 582,815
1 Claim. (Cl. 299-129) The object of this invention is to provide an inexpensive easily operated semi-automatic outlet nozzle that may be operated either as a round stream outlet nozzle or as a fiat spray outlet nozzle at the instant will of the operator.
This invention is adapted for general use for any purpose where it is desired to be able to switch rapidly from a round stream to a flat stream; but it is particularly intended for use with fire extinguishers where both types of spray may be needed and where it is important to be able to switch from one to the other rapidly.
The invention, therefore, comprises a device, example of which is hereinafter described and shown in the accompanying drawings, in which Fig. 1 is a central longitudinal section thru the device, the parts being in a position to discharge a round jet or stream; Fig. 2 is the top plan view of the device shown in Fig. 1; Fig. 3 is a side elevation of the construction as shown in Fig. 2; Fig. 4 is a central longitudinal section thru the nozzle with the parts disposed in position to create a flat wide spray; and Fig. 5 is a top plan view of the construction shown in Fig. 3.
In the drawings, the numeral 11 represents the hose or a pipe or a handle to which the nozzle is attached and thru which the liquid to be discharged is fed to it. The numeral 12 is a short circular nozzle extending out from the end of the tube 11 to carry the operative parts of the nozzle and having a stud 13 extending into the handle 11. This nozzle 12 has a circular bore 14 adapted to discharge a stream of liquid which is round in cross-section, as shown at 15 in Fig. 1.
The fiat spray, as shown at 16 in Fig. 4, is to be discharged from a flat nozzle 17 having a flat orifice at 18. This flat nozzle is pivoted to the nozzle 17 at 19, cars 20 being provided upon the nozzle 12 for this purpose. This flat nozzle 17 has an opening 21 in its upper wall, which opening is preferably provided by bending the outer wall of the nozzle 17 inwardly, as shown at 22, just below the opening 21, the bent-in portion 22 thus serving as a partition separating the opening 21 from the body of the flat nozzle 17 beyond it. A spring 23 is compressed between a stud 24 on the round nozzle 12 and a pocket 25 on the flat nozzle 17, the spring thus serving to hold the flat nozzle 17 in the position shown in Fig. 1, in which liquid discharged from the bore 14 shoots outwardly thru the round 2,823,076 Patented Feb. 11, 1958 opening 21, without any obstruction, and therefore rctains its circular form. The flat nozzle 17, however, has a backwardly extending handle or finger piece 26, the depression of which rotates the nozzle 17 about its pivot 19 to the position shown in Fig. 4, in which position the fiat nozzle 17 is moved in such a way as to direct the stream from 21 below the partition 22 and against the top wall of the flat nozzle 17, by which it is caused to flare outwardly to fill the entire elongated orifice 18 and to eject a stream conforming to the shape of that orifice.
It will thus appear that by depression or release of the handle 26 the stream ejected by the nozzle can be changed from a circular stream to a flat stream instanteously, and changed back again at will. This is particularly important in fire extinguishers where, as is well known, the circular stream can be made to carry to a greater distance than a flat stream, whereas the flat stream gives greater coverage and both of these are important in reaching and quenching the heart of the fire.
Moreover, it frequently happens that the heart of a fire lies in the burning material below the surface fire, and the impact of the small circular jet helps to dislodge the upper materials to reach this burning heart while the flat stream assists in dispersing the fire-extinguishing fluid over the maximum area as quickly as possible.
It will be obvious also that the spring 23 may be placed above the round nozzle 12 and the handle 26 below it, so that the spring 23 will urge the flat nozzle to the position of Fig. 4, and a compression of the handle will cause the flat nozzle 17 to assume the position shown in Fig. 1, so that the nozzle would normally give a flat spray but this could be altered to a round spray at will.
What I claim:
A semi-automatic outlet nozzle for discharging either a round or a flat spray, comprising a short cylindrical nozzle member and a flat spray member pivoted to said cylindrical nozzle member and substantially completely enclosing the mouth thereof, said flat spray member having an opening in one wall thereof terminating in a cut-off edge, said edge being in alignment with the end of such cylindrical nozzle, the pivot of said flat nozzle member being situated to permit said cut-off edge to be moved to bring said cut-ofi edge either above or below a jet issuing from said cylindrical nozzle member, said flat spray member having its top wall in the form of a deflector plate in position to intercept and deflect a jet impinging upon it from said cylindrical nozzle into an elongated opening at its end, and simultaneously spreading that jet to the full width of the elongated opening.
