HOSE-NOZZLE.

SPECIFICATION forming part of4 Letters Patent `No. 633,069, dated September 12, 1899. Application filed December 20, 1898. Serial No. 699,791. (No model.)

To (LIZ wiz/mn, it may concern.-

lle itknown that I, JOSEPH BUSHA, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, vhave invented certain newiand useful Improvements in Hose-Nozzles, of which the following is a specification.

This invention has especial reference to that type of hose-nozzles for throwing both sprays and solid streams; and its object is to provide a nozzle which will be of simple, durable, and inexpensive construction and capable of being most quickly and easily converted from one throwing a solid stream only to one throwing both a spray and a solid stream at once.

The invention consists, first, in ya nozzle having separate valves for controlling the passages through which the solid stream and spray, respectively, flow and a means for adjustin g said valves common to both of the same and operative to open both valves at once, as contradistinguished from'a single rotative valve having separate ports for the respective passages and operative to open one passage only ata time, and from a construction in which both the spray andsolid-stream passages may be open at once, but are oper# ated by mechanisms wholly distinct and independent of each other; second, in a nozzle having separate valves for controlling the passages through which thesolid stream and spray, respectively, How and a Ameans for ad# justing said valves corn-mon to both of theV same, said adjusting means being operated to open one valve only (preferably the valve controlling the issue of the solid stream) or both of the valves together, at will; third, in a nozzle having separate valves for controlling. the passages through which the solid streamf and spray, respectively, flow and a common:y adjusting means for said valves, said parts being relatively consti-noted and arranged soI that one of said valves will have an initial movement sufficient to openthe passage-way controlled by it independent of the other valve, thus opening one passage-way without opening the other, and said other valve will be moved from its seat by further movement of the first valve; fourth, in the details of construction entering into and constituting the preferred embodiment ofthe invention,

all substantially as hereinafter described and claimed.

In the accompanying drawings l have shown a nozzle constructed in accordance with my invention and which is preferred by me, because it embodies all the features above named and carries out the several novel ideas contained in the complete invention in what I deem to be the most advantageous manner.

ln said drawings, Figures 1, 2, and 3 are longitudinal sections through a nozzle containing my improvements, the first showing the valves 'arranged to close both passages, the second showing the passage for the solid stream open and the passage for the spray closed, and the third showing both passages open. the valve for controlling,r the spray. Fig. 5 is a transverse section enlarged on the line .fr of Figs. 1, 2, or 3. Fig. 6 isa similar section on the line y y of Figs. 1, 2, or 3. Fig. 7 is an enlarged perspective view of the valve for controlling the passage through which the solid stream fiows. Fig. 8 is a view of the forward portion of the nozzle-shell, looking into the rear end thereof. Fig. 9 is a detail view showing the stuffingebox around the valve-stem.

The same letters and numerals of reference designate the same parts in the several figures.

The shell consists of a forward portion A and a rear portion B,- threaded together at O. Said portion A is reduced in diameter at its front end to form the wall 3, which is per forated, as shown at 4, or otherwise suitably constructed to cause the water to issue in a spray.

1 designates the tip or tube which provides the passage-way for the solid stream. This tip projects inward into the shell and isv of such diameter relative to the latter as to leave a chamber 2 between it and the shell for the spray.

5 Idesignates the valve which controls the Hflow of water into the tube 1 and which preferablyhas a conical forward end,as is usual in this type of nozzles. This valve 5 is designed to be seated within the inlet end of the tube 1, while a separate valve G is pro'- vided for closing the inlet end of the spraychamber 2 and engages an annular shoulder Fig. et is a detail perspective view of.

7, formingihe seat therefor. The valve 6 is of tubular form and encircles the rear end of said tube 1 and projects forward into said chamber 2. Ithas a reduced portion 8 of such diameter relative to the seat 7 as to permit water to flow through said seat and out through the sprayopenings 4 when the valve is in its rearward position with its wider portion 9 out of engagement with said seat. The inner wall of the valve 6 has a series of deep grooves 10, whereby in operation a water-cushion is provided which prevents leakage. The valve 5 is mounted on the forward end of a stem 11, which projects into and is guided by an opening formed in a vertical wall 12, located in the rear part A of the shell. Said stem has a cross-bar 13, which projects laterally therefrom in both directions through coinciding openings 14, formed in the cross-wall 12 and in the wall of said part B. The openings 14 are of suoli length as to permit the har 13 to move forward and rearward therein during the adjustment of the valve 5 to and from its seat. The outer ends of said crossbar are threaded, as shown at 15, and are engaged by the threaded inner wall of an adjusting-sleeve 1G, which loosely encircles said rear part B, so that it may be turned thereon; but when the parts are assembled it is held against longitudinal movement by the shell member Aat one end and the flange 17 at the other end. It will be seen that the valve 5 will be adjusted to or from its seat according to the direction in which said sleeve is turned. This sleeve and cross-bar constitute the preferred means for adjusting said valve, but other suitable means may be employed without departing from the spirit of the invention.

Projecting rearward `from the rear end of the valve G are two arms or valve-stems 18, the rear ends of which are connected by a cross-arm 19, having an opening 20, through which the stem 11 extends loosely. The valves 5 and 6 are relatively positioned, so that the former may be moved rearward from its seat a certain predetermined distance (sufficient to permit the ow of water through the passage controlled thereby) without aecting the position of the other vvalve 6. A projection 21, herein provided by the rear portion of the valve 5, is arranged to engage said cross-arm 1Q (which constitutes a projection movable with the valve 6) when said valve 5 has been moved from its seat a distance farther than the predetermined one referred to for forcing said valve 6 from its seat and opening the spray-passage. During the initial movement of the valve 5 thepressure of inflowing Water will usually be sufiicient to hold the valve 6 to its seat; but in order to supplement the power of said water, and more especially to hold the valve 6 to its seat While the nozzle isA not in use and prevent chattering when the nozzle is being drawn rapidly from place to place, I prefer to provide a coiled spring 22, which encircles the valve-stem 11 and 23b between its flange and said part 24. The

stufiing-box thus formed obviously prevents leakage of water around the valve-stem.

From the above the operation of my invention will readily be understood to be as follows: Vhen the parts are in the position shown in Fig. 1, the valve 6 Will be held to its seat by the spring 22 and the valve 5 will be held to its seat by the coaction of the crossbar 13 (which is at the forward end of the opening 14) with the sleeve 6. 1f now the sleeve be turned in the proper direction, said valve 5 will be drawn from its seat and its portion 21 brought into engagement with the cross-arm 19. At this time the inlet to the tube or passage-way 1 is open and a solid stream will issue from the nozzle. If it is not desired to use the spray, the parts are left in the position they now occupy, and when the spray is needed in addition to the solid stream said sleeve is given an additional turn or two, thus forcing the valve-stein 11 and the valve 5 farther rearward, causing the power of the water-pressure and the spring 22 to be overcome and forcing valve 6 from its seat. iVhen it is desired to shut off the spray, the sleeve is turned in the reverse direction, so asV to force the valve 5 forward and permit the water-pressure and sprin g to return valve 6 to its seat. 1f it is desired to shut oi the nozzle entirely, said reverse movement of the sleeve is continued until the valve 5 has also been seated.

IOO

The valve 5 herein shown is of that wellknown type of pointed-cone valves which are placed concentrically in the nozzle ajutage and adapted to be so operated in connection [IOV therewith as t0 cause the nozzle to throw a me, but is not entirely essential to the opery ativeness or practicability of the invention.

A serious objection has been experienced with spray-valves, especially when the nozzles have been connected directly with firehydrants, as is sometimes done in certain cities having high water-pressure when the fire to be extinguished is a small one and may be reached by suchcity pressure, owing to the quickness with which the spray becomes clogged with dirt, the., and thus unt for further use until cleaned. In order largely to overcome this disadvantage, and thus render it practical to connect the nozzle directly with lire-hydrants when desirable, I provide the rear end of the nozzle with a strainer 25,which is in the form of a tube having a front wall 26 and perforated side and front walls. The side walls ofthe tube are out of contact with the adjacent wall of the shellsection B,within the rear end of which latter the strainer is preferably located, and the rear end of said strainer has an outwardly-projecting annular flange 2T, by which it is held rigidly in place when the nozzle is attached to the hose and whereby it may be quickly removed and replaced when desired. The strainer may also be found to be very useful when the nozzle is connected directly with a lireengine as a su pplemental means to the strainerin the latter.
