HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 388,159, dated August 21, 1888.

Application filed March 9, 1888.

To aZZ whom it may concern.-

Be it known that I, EDWIN 1t. Torrmnsoma citizen ofthe United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Hose-Nozzles; and I do hereby 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.

Myinvention relates to certain new and useful improvements in hose-nozzles, but has especial reference to that class of nozzles from which water may be caused to issue in a solid stream, a coarse or fine spray, or in what is termed a parachute spray, and with these ends in view my invention consists in the de tails of construction and combination of elements, such as will be hereinafter fully set forth, and then specifically designated by the claim.

In order that those skilled in the art to which my invention appertains may fully understand its construction and operation, I will proceed to describe the same, referring by letter to the accompanying drawings, forming a part of this specification, and in which Figure 1 isa perspective illustrating my improved nozzle with what I term the deviator swung into position to produce a parachute spray; Fig. 2, an elevation showing the nozzle stopped after the manner of my improvement; and Fig. 3, a detail perspective of my improvement detached from the nozzle proper, the stopper being shown in section.

Similar letters denote like parts in the several figures.

A is the nozzle, having cast therewith a cheek-piece, B. O is a frame which is pivoted to said cheek-piece, so as to swing readily.

D is what 1 term a deviatorj and consists in an inverted cone depending from an arm, E, formed with or rigidly secured to said frame in such manner that when the latter is swung in the proper direction said cone will overhang the nozzle, for the purpose presently set forth. Secured to the frame and projecting inwardly therefrom is a short shaft, F, around which is a softrubber roller, G, having a metallic bushing, H, which latter forms a suitable hearing, so as to insure the ready SerialNo. 266,665. (No model.)

turning of said roller on the shaft. I is a thumb-nut run on said shaft for the purpose of securing the roller as against displacement.

J K are stops which are formed with the frame, and are adapted to limit the swing of the latter in both directions by striking against opposite sides of the cheek-piece. The location of these stops is such that they will perform their functions when the deviator and stopper are respectively immediately over the nozzle, thereby preventing any overthrow of the frame.

Prior to my invention hose nozzles have been made in some instances with a conical Valve within the tip,the apex of the cone pointing outward; but a serious objection to this construction is that the adjustment of said valve does not diverge the stream, but merely causes it to advance in a rather ragged cylindrical form. Again, the said valve does not afford any facility for guiding or directing the stream after it has issued from the nozzle. The location of an inverted cone immediately over the nozzle causes the stream of water to diverge in apcrfect parachute form, while at the same time, by slightly shifting the cone to one side, the parachute will become ovoidal in cross-section, and by simply swinging the frame the nature of the stream is readily changed from a solid to a parachute spray, or vice versa. The stopper, having a rotary action on its shaft, readily plugs up the nozzle when the frame is swung in the proper direc tion. Furthermore, the stopper has another function-namely, the effecting of a flat sheet spray extended in a plane at an angle to the axis of the nozzle. This latter is accomplished by partially closing the nozzle by means of the stopper, thereby causing the stream to drive against the stopper and shoot therefrom at an incline and in the form of a thin sheet.

By the use of my improvement there is no adjustment of waste nuts or screws to compensate for leakage, since the operation of my entire construction is positive.

One of the most striking and important advantages attcndant upon the use of my improvement is the fact that the nozzle cannot possibly get clogged by sand or dirt, since the stopper operates to completely close the opening in the nozzle, whereas,ordinarily, the usual position immediately beyond the nozzle, the shaft extending from the frame, and the rub- 15 ber roller mounted on said shaft and adapted to be swung across and against the end of the nozzle, substantially as and for the purposes hereinbefore set forth.

In testimony whereof I affix my signature in presence of two witnesses.

EDWIN R. TOMLINSON.
