SPECIFICATION forming part of Letters Patent No. 721,665,l dated March 3, 1903.

. Application led April24,1902. Serial No. 104.540.5010 model.)

To all wtowt it may concern.:

Be it known that I, JOSEPH BUsHA,a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Hose-Nozzles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention hasparticular reference to certainim provements in that class of hose-nozzles for remens use constructed Vto throw both spray and solid streams; and it consists expensive construction havingV means byA which it may be caused to throw a `iine or a coarse spray at the will of the operator.

Another object of the invention is to provide a nozzle constructed to throw either aV solid stream alone or both a spray and a solid stream at once and wherein the adjustment of the valve which controlsthe access of wa-V ter to the spray-chamber is accompanied 'by an adjustment of a spraying devicewhich controls the outflow of the water from said chamber and causes it to be either in the form of a fine spray or in the form of a coarse spray at the will of the user.

These and other objects of the inventionV are accomplished by the construction illustrated in the accompanying drawings, in which- Figure l is a longitudinal section through a hose-nozzle containing my improvements,

showing the position of the parts when water is shut olf from both the passage for the solid stream and the spray-chamber. Fig. 2 is a similar view showing the position of the parts when the passage for the solid stream is open and the spraying-chamber is closed. Fig. 3 is a similar view showing the extreme position ofladjustment of parts to open bothV the passage for the solid stream and the inlet to the spray-chamber@ Fig. 4 isadetail side view of the tube through which the solid stream flows and its attached parts for controlling the spray. Fig. 5 is a detail viewfof the valve which controls the flow of water for the solid stream, together with a stem and threaded piece, which are preferably employed as apart of the operating means therefor. Fig. 6 is a side view of thenozzle complete. Fig. 7 is a crosssection on the line 7 7 of Fig. 6.V Fig. 8 is a detail View, partly in section, of the means through which the solid stream issuesfrom the" nozzle and the parts secured thereto, showingI a modified form of vspraying devicethe casing being in section and broken od near its front end. Fig. 9 is a detail view looking at the rear end of Fig. 4 or Fig. 8.

The same numerals of reference designate the same parts in all the ligures.

The casing of my improved hose-nozzle may be composed of the front section l and the rear section 2, having a forwardly-extending reduced p art 3,upon the forward end of which the rear end of'said parti is threaded. Said front section l has an inwardly-extending bevel or inclined forward extremity 4, and between its ends it is formed to provide an annular valve-seat 5. vLocated in the forward portion of said section lisalongitudinally`movablefw carrier (i, which for reasons hereinafter stated is preferably in the form of a tube and the rear end of which is formed or provided with an annular valve 7, which controls the inlet of water to the spray-chamber 8. Inorder to guide the tube 6 in its movements, it is preferably provided with longitudinal ribs ,9,the outer edges of which engage the inn'erwall ofthe forward portion of the section l. Said tube 6 carries an annular valve or device V10 at its forward portion, which has a circumferential bevel or inclinationlLrWhich coperates with the beveled or inclined forfwardend'i of the section l to cause the water in the other figures of the drawings, so as to be adjustable on said tube 6, and when the latter construction is employed the valve is preferably formed with a hexagonal or other angular end 12, adaptedto be engaged by a Spanner or other suitable wrench for convenience in adjusting it.

1t will be observed that while the tube Gis being adjusted to open or close the inlet to the spray-chamber the spray-valve 10 is similarly being adjusted toward and from the beveled front end 4 of the shell-tube 1. Thus by properly adjusting said tube 6 the Water may be caused to issue from the spray-chamber in the form of a spray, which may be graduated as to fineness and force at the will of the operator simply by adjusting the tube 6. When the preferred construction of sprayvalve 10 is employed, it may be adjusted independently of adjustment of the tube by screwing it forward or rearward on said tube, as is apparent.

The modified construction shown in Fig. 8 is intended especially to satisfy the desires of those who prefer a construction which throws a narrow instead of a wide spray.

I have shown the improvements hereinabove described embraced in a structure to which it is more especially adapted, wherein the nozzle is adapted to throw both a solid stream and aspray, and in said construction it is intended to utilize the part 6 not only as a carrier for the valves at both the inlet and outlet of the spray-chamber 8 and as the inner longitudinal wall of said chamber, but also to employ it to provide the passage through which the solid stream iiows, and to this end it is made in the form of a tube, as shown, and the inlet to it is controlled by a valve 13, which seats against the rear extremity of said tube. The valve 13 herein shown is of that well-known type of pointedcone valves which are placed concentrically in the nozzle-ajutage and adapted to be so operated in connection therewith as to cause the nozzle to throw a solid stream of any required volume, from nearly the full diameter of the discharge-openingto a small jet, without cutting off or diminishing the projectory force and pressure of Water at the point of discharge from the nozzle. This type of valve is preferred by me. Preferably the valve 13 is adjusted to and from the tube 6 to close and open the passage through said tube.

' For adjusting the valves and the tube 6 to cause the nozzle to throw either a solid stream alone or both a solid stream and a spray at once and to regulate the tineness of said spray l prefer the means shown in the drawings wherein the tube 6 is provided with two rearwardly-extending arms 13, the rear ends of which are connected by a cross-bar 19, having an opening 20, throughv which the stem 14 of the valve 13 loosely extends, and said valve-stem is formed rearward of said cross-bar 19 with a slot in which is fitted a cross-bar 15, having threaded ends which are engaged by a threaded adjusting-sleeve 16, which when operated in one or the other direction will cause the threaded cross-bar to move longitudinally of the nozzle, and thereby cause or permit the valve 13 or the tube 6, or both said valve and tube,to be adj usted in a direction and to an extent which accords with the direction and extent of rotary movement given to said sleeve 16. For convenience in operating said sleeve it is preferably provided with ribs 16, whereby the grip of the fireman thereon is utilized to the fullest extent.

The sleeve-16, valve-stem 14, and crossbar 15 are guided in their movements by the forwardly-extending reduced part 3 of the shell-section 2 and by a rib 21, with which said part 3 is formed, said rib extending longitudinally of the part 3 and having a central longitudinal opening 22 for the valvestem and having longitudinal slots 23 at opposite sides of its central opening, which slots coincide with that in the valve-stem and also coincide with slots 24 in opposite sides of the wall of said part 3, as shown best in Fig. 7. The bottom of said rib has a depression 25, which forms a pocket to receive the stem 14 when the latter is in its lowermost position of adjustment. The adj usting-sleeve 16 eucirc'les said part 3 and is permitted to have axial movement thereon in either forward or rearward direction, but is held against longitudinal movement.

Then the parts are assembled, the valvestem 14 extends through the opening 22 in the rib 21, and the cross-bar 15 projects laterally from both sides of said valve-stem and extends through the coinciding openings in said rib and the wall of said portion 3, which openings are of such length as to permit the cross-bar 15 to travel therein a distance equal to the extent of travel of said stem.

The parts are so positioned that the valve 13 has a movement relative to the valve 7 and cross-bar 19 a distance sufficient to open the inlet to the tube 6 without affecting the position of said valve 7, and it may be left in said position if it is not desired to use the spray. When said valve has moved said distance, its rear end has been brought into engagement with the cross-bar 19, and if it is desired to open the spray-chamber to the iniiow of water thereinto the adjusting-sleeve 16 is given an additional turn or two, according to the character of spray it is intended to use, thus pulling the valve 13 farther rearward and causing it, by reason of its engagement with said cross-bar, to move the same and the tube 6 in the same direction, thereby opening the inlet to the Spray-chamber and adjusting the spray-valve 10 toward the mouth 4. When the character of spray desired has been produced, further adjustment of the sleeve 16 is discontinued,and the parts will be held in position without necessitating provision of special means therefor. When the preferred form of the spray-valve 10 is ICO IIO

used and the inlet-to the spray-chamber is part of the device, and consequently without affecting any other part of the device by adjustment of said valve 10 on the tube.

During the initial movement .of the valve 13 from its closing position (shown in Fig. 1) to the position shown in Fig. 2 the pressure of iniiowing water may be suiicient to hold the valve 7 to its seat; but in order to supplement the power of said Water and to return the valve 7 to its seat when the valve 13 has been adjusted to permit the latter a spring 26 is coiled around the valve-stem 14 and bears at one en d upon the forward end of the cross-rib 21 and at the other end upon the rear surface of the cross-arm 19.

It will be observed that the tube 6 is so related to the forward shell part l as to form the spray-chamber 8, above mentioned, between the same, the outer wall of said chamber being formed by the inner wall of said shell part and the inner wall of said chamber being formed by the outer'wall of said tube, and that the seat for the valve 13, which controls the solid stream, is formed on said tube. By this means the construction of the device is reduced to the simplest possible form,'an'd, moreover, in the adjustment of the parts rearward to open the spray-chamber (from that shown in Fig. 2 to that shown in Fig. 3) and in the adjustment of said parts forward to close thespray-chamber (from that shown in Fig. 3 to that shown in Fig. 2) the relative position of the valve 13 and its seat remains unchanged, as said tube, which carries said valve-seat, moves with the valve during said adjustment, and the movement of said valve 13 relative to said tube is confined to its adjustment, in which it opens and closes the inlet to said tube.

If desired, the tube 6 may serve as the noz- Zle-tip, as shown in most of the figures of the drawings, or, if desired, a supplemental tip 30 may be screwed or otherwise secured thereto, as shown in Fig. 8.

The valve 13 is preferably threaded upon the forward end of its stem 14: for-convenience in assembling and disassembling the parts,as shown in Fig. 1.
