C. R. FLEMING-WILLIAMS NOZZLE FOR THE DELIVERY OF WATER 0R OTHER LIQUID UNDER PRESSURE Filed Sent. 1921 CLIFFORD ROGER FLEMING-WILLIAMS, OF LAKE W'INDERMEBE, ENGLAND.

NOZZLE FOR THE DELIVERY OF WATER OR OTHER LIQUID UNDER PRESSURE.

Application filed September Tocll whom it may concern 1 Be it known that I, CLIFFORD ROGER FLEM- ING-VVILLIAMS, a subject of the King of Great Britain, residing at Hill ofUaks,

Lake lVindermere, in the county of Lancaster, England, have invented a new or improved Nozzle tor the Delivery of Water or Other Liquid Under Pressure (for which I have'iiled an application in Great Britain on March 19, 1919, No. 6899), of which the following is a specification.

This invention relates toa new or improvide nozzle and the object aimed at i to produce a nozzle of simple construction and capable of a high degree of efficiency, the said nozzle being of the type comprising a restricted orifice at a distance from the delivery orifice and adapted without the use of valves, for projecting either a solid concentrated jet of water or other liquid at a relatively high velocity, or, at will, a more dif fused jet covering a larger area and at a materially lower pressure or velocity.

According to this invention, the nozzle stricted inlet opening is preferably made convex towardsthe flow, and the discharge or outlet orifice is conveniently provided with an annular flaring lip. The bulb or enlargement may be globular, but whether globular, egg-shaped or of less diameter axially than transversely, it may be provided with a rib or ribs on the interior and in the neighbourhood of the-outlet orifice.

These ribs may be concentric and parallel with the delivery orifice, or they may be,

axial or inclined to the axis. Upon turning on the water, a high velocity jet may be projected without touching the sides of the tubular body or bulb. If, then, a diifused jet is required, the delivery is checked as by placing the hand over the outlet orifice, whereupon the li uid will be obstructed in the nozzle and will form eddies therein, so that it is delivered in a diflused or annular form at a materially lower pressure or velocity than before.

In order to enable this invention to be 1, 921. sea-.11 No, 497,778.

readily understood, reference is made to the accompanying drawing in which: Figure l is a side elevation of a nozzle de vice constructed in accordance with these improvements, and

Figure 2 is a longitudinal section through the nozzleseen in Figure 1. i

Fig. 3 is a longitudinal section of a modified form.

Referring to, the drawing, a is the tubular part of the nozzle formed with the restricted inlet or opening 6 at the inlet end,that is to say the end that is inserted into the hose or other pipe. The tubular part a merges into a bulbous part 0 which, as shown in the drawing may be globular, although it may be. of any bulbous formation, as indicated above. The bulbous part 0 may be formed with a flared lip (Z around the delivery oricIJ;

formed without it as indicated in Fig. 3.

The exterior of the tubular part may be I formed with ribs 9 or the like for improving its hold in a hose pipe in known manner.

In the construction illustrated, the interior of the bulb c is formed with annular ribs,

serrations, or other suitable projections it, these being preferably concentric with the delivery orifice and adjacent thereto. It' will be noted that the portionof the nozzle surrounding the inletopening Z) .is made convex. towards the direction of the flow, this formation being preferred in practice.

In use, the nozzle is fitted on to a hose in any suitable manner, as by forcing the tubular part a with the ribs 9 into the end of a hose pipe, or by screwing, or by any other known means. Upon turning on the water,

a jet may pass straight through from the inlet opening 6 to the delivery orifice c, without touching the interior of the tubular part a or the bulbous part 0. Such a jet would have a, high velocity and be of a solid and concentrated form. When a diffused jet is required, the hand, or any other obstruction, is placed over the delivery orifice e or in the way of the jet so as to sufficiently obstruct the same. Thereupon, the nozzle or bulb becomes more or less filled, so that the water strikes the interior and particularly the ribs or the like at h. This action will continue after removing the hand, so that the user will now have the diffused jet, or jet of lower velocity, as will be readily understood. When the'high velocity jet is The nozzle. device may beinade wholly or.

partly of metal, but it may also be made of india rubber, vulcanite or other suitable material. If the bulb be made of rubber, the momentary cessation or retardation of the flow may be effected by pinching the bulb.

A nozzle constructed in accordance with these improvements, may be used wherever it is. required to deliver water or other liquid soinetimesin a concentrated jet form'and sometimes in diffused form. For example, in washing coach Work, and where the mud is thickly caked, only astrong jet will remove the mud, but a diffused jet is essential When the same is to strike the delicate surface of the paint or varnish of thecoach Work. j

I claim 1. A nozzle of the kind herein referred to and comprising a tubular portion having a restricted orifice at one end, and a bulbous chamber of larger cross sectional dimensions than said tubular portion, said chamber communicating with said tubular portion and having a relatively large delivery orifice in axial alignment with said tubular. portion substantially as set forth.

2. A nozzle of the kind herein referred to and comprising a tubular part having a restricted orifice atone end, a bulbous chamber connected with said tubular portion and having larger cross sectional dimensions than said tubular portion and a delivery orifice of" relatively large diameter opposite the point of connection of said tubular portion, and formations presenting an uneven sur face on the interior of said chamber substantially as set forth.

3. A nozzle of the kind herein referred to and comprising a tubularpart having a re 'stricted orifice at one end bulbous chamher connected with said tubular portion and .having larger cross sectional dimensions than said tubular portion and a delivery orifice of relatively large diameter opposite the point of connection of said tubular portion, and ribs on the interior surface of said chamber said ribs being adjacent to the parallel with said orifice substantially as set forth.

i. A nozzle of the kind herein referred to and comprising a tubular part having one 7 end closed by an outwardly convex well formed with a small central aperture andja hollow bulb joined to the opposite end of said tubular portion, said bulb having a dc.- livery orifice of relatively large diameter axially aligned with said aperture substam tially as set forth. v

5. A nozzle of the kind herein referred to and comprising a tapered tubular part formed with a restricted inlet opening at its small end and merging into a globular enlargement at its delivery end, said enlargement be ng formed with a relativelylarge delivery or fice axially aligned with said inlet opening substantially as set forth.

6. A nozzle of the kind herein referred to and comprising a tubularpart' having a" restricted inlet orifice at one end and a de'- formable bulb at its opposite end said bulb having a delivery orifice of relatively large diaii-ieter axially aligned with said inlet orifice substantially as set forth.

l. A nozzle of the kind herein referred to and comprising a tubular portion with a restricted inlet orifice atone end and a bulbous chamber at the other end, saidchainber having a deliveryoriiice of smaller area than the greatest cross sectional area of'said bulb but of much larger areathan saidinlet orifice substantially as. setv forth.
