HOSE-NOZZLE.

SEECIFIGATION forming part of Letters Patent No. 699,384, dated May 6, 1902.

Application filed February 24, 1902l Serial No. 95,223. (No model.)

To al?, whom t may concern.-

Be it known that I, HENRY GIBBs, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Hose-Nozzles, of which I do declare the following to .be a full, clear, and exact description, reference being had to the accompany ing drawings, forming part of this specification.

Figure l is a View in central vertical section through a hose-nozzle embodying my invention. Fig. 2 is a detail View, in side elevation, of the outer part of the nozzle, with the valve and valve-stem attached. Fig. 3 is a view in horizontal section on line 3 3 of Fig. 2. Fig. et is an inverted end view of the parts of the nozzle shown in Fig. l. Fig. 5 is a detail side view of the valve-stem and valve.

This invention has for its object to provide a simple and effective construction of hosenozzle whereby the water may be .caused to discharge from the nozzlein a more or less solid stream or in spray form and whereby also the discharge of water through the noz vzle may be completely cut off.

The invention consists in the features ofi n1- provement hereinafter described, illustrated in the accompanying drawings, and particularly defined in the claims at the end of this specification.

A designates what for convenience I term the.base portion of the nozzle. This base portion A is provided upon its interior with the usual screw-threads a, whereby the noz* zle maybe coupled to the hose, a packing ring or gasket a being preferably placed at the inner end of the threads a. In the base portion A is formed a diaphragm a2, provided with au orifice n.3 and with a raised Valve-seat a4, and above the Valve-seat a4 is formed a chamber' a5. The base portion A is formed with a tubular bore to receive the inner part of what for convenience is termed the body portion B of the nozzle, a suitable packingring b being preferably interposed between the body portion B and the wall of the base portion A. The body portion B is formed with an annular groove b', into which projects the end of a screw C, that passes through a threaded hole formed in the wall of the base portion A. By this` means the body portion B of the nozzle is revolubly connected with the base portion A. The inner end of the tubular body portion B is formed with one or more lateral ports or'perforations b2, two of such ports or perforations being shown in the drawings. The lower end of the tubular body portion B is interior-ly threaded to receive the eXteriorly-threaded portion of a tubular stem D, this stem being formed with one or more ports or perforations d, corresponding to the ports or perforations Z22 in the wall of the body portion B.

As shown, the stem D carries a valve E, adapted to close against the valve-seat a", and, as shown, the stem D has an extension D', that connects with the body portion Ain such manner as to hold the valve and stem against revolution, while permitting a longitudina-L movement to such parts. Preferably the extension D is formed as a Hat web or Apart adapted to set within recesses a6 in the The diaphragm a of the body portion A. valve E is preferably, although not essentially, formed separate from the stem D, since by forming the valve E as a separate ring this valve may be made of rubber or like vmaterial best adaptedfor effectively closing against the valve-seat a,

From the foregoing description the operation of the nozzle will be seen to be as follows: If the parts are in the position shown in Fig. 1 of the drawings, the waterwill pass in the direction of the arrow into the base portion of the nozzle, through the opening in the diaphragm o., into the chamber a5, thence through the coincident ports b2 and d into the body portion B, from which it will discharge at the end b4 of the nozzle. Now by turning the body portion B of the nozzle the coincidence between the ports b2 of the body portion and the ports d of the stem D may be more or less broken, as shown in Figs. 2 and 3 of the drawings, and when this is done the stream of water will be broken upinto spray, and thus broken up will `be caused tovpass with more or less of a swirling motion through the discharge end b'L of the nozzle. When'the body portion B is turned so as to cause :its

IOO

` having an annular chamber, a tubular body yagainst the valve-seat a, when the passage lforations of the tubular body and means for blank wall to come opposite the ports d of the stem D, the passage of Water through the nozzle will be practically cut 0E, although there may still be more or less leakage of water around the threads between the stem D and the body portion B. Hence it is that I prefer to provide the tubular stem D with a valve E, and it will be seen that by turning the body portion B the valveE can be caused to move downward until it firmly closes be comholding said stem or part against revolution as the tubular body is revolved, whereby the coincidence between the perforations of the tubular stem and of the tubular body may be varied to change the character of the stream through the nozzle.

2. A hose-nozzle comprising a base portion revolubly connected to said base portion and having a laterally-perforated part extending into said chamber, a tubular stein or part located within said chamber and having a laterally-perforated part engaging the inner end of the tubular body and moans for holding forations adapted to coincide with the perforations ofthe tubular body, means for holding said stem or part against revolution as the tubular body is revolved, said stem or part being provided with a valve adapted to close against the valve-seat of the base portion.

4. A hose-nozzle comprising a chambered base portion having a valve-seat, a tubular body revolubly connected to said base portion and formed with one or more lateral perforations and with a Screw-threaded inner end, a screw-threaded tubular stem comprising a valve and engaging the inner end of said tu- -bular body and provided with one or more lateral perforations and means for holding said stem against revolution as the tubular body is revolved.

5. A hose-nozzle comprising a base portion A having a valve-seat a4 and a chamber d5, tubular body B having an interiorly-threaded and laterally-pcrforated inner end extending into said chamber a5 and revolubly connected with said base portion, an eXteriorly-threaded and laterally-perforated tubular stem D engaging said tubular body and carrying a valve adapted to close against the valve-seat 1,4 and a web or part D for holding said stem D against revolution.
