Patented Sept. 11, 1951 NQZZLE FOR THE DISCHARGE oF- LIQUIDS Thomas A. Henshaw, Elland, England, assignor to- Nu.-Swift,,Limited-, London, England Application March 5, 1948; Serial No. 133137 In GreatBr-itain Marchll, 1947 Myrinventiorrin-orr ating to nozzles for the discharge of liquids has particular reference to nozzles'iior the discharge of liquidfire-extinguishing media; but a nozzleaccording. to or embody ing the invention. is, as willsbezapparentirom the description to be hereinafter given, applicable with advantage for-other purposes.

object of the invention is to provide an. improved constructionof nozzle designed: to give, at -will, a. discharge in' theiorm of a jet, or of a. spray, or what may be termed a fog or mist, that istosay a spray-of exceedingly finedivision.

A further object is to provide a nozzle of such construction. that even: when dealing with flows; of largeavolume and at high pressure the change from: one form of discharge toanother can be made with a minimum of'efiort;

My-improved nozzle is characterized: by the interposition between. the conduit through. which the liquid. to be discharged is led to the nozzle, andwhat may beter-med a circumferentially-ad-.. justable discharge-controller,- of a flexible dia-. phragm. formed with a serie of openings into, or away from, completeor partial coincidence withwhich a series of passages through the discharge controller can be brought; the openings in the flexible-diaphragm being so disposed and the passages through the discharge controller being so formedthat by appropriate circumferential ad'- justment or rotation of the controller either a solid jet, or a spray of anydesired' fineness down towhat may be termed a mist or fog'can be discharged. It maybe arranged that at all times apassage-way, preferably'centrally disposed, will be affordedthrough the flexible diaphragm and discharge controller; in which casethe nozzle will be incapable of use as a shut-off valve; Ii? such a valve is required it maybe included in the-pipe orconduit leading to the discharge nozzle, or alternatively the passages in the discharge controllermay be so disposed that'the discharger itself constitutes a simple shut-off valve.

In the accompanying drawing,

Fig. l is a sectional elevation of a. nozzle ac! cording to one embodiment oftheinvention; and

Fig; 2. is a similarview to Fig. 1, but having the section taken ona difierentplane;

Fig. 3' is an end view of the nozzle, looking; in the, direction of the arrow 3 in Fig. 1;

Fig. 4 is; a diagram showing'a somewhat different arrangement, of theports or passages from. that in the-nozzle shown in Figs. 1-3.

Referring to the drawings, and firstly to Figs. 1- to. 3, a'represents a nipple adapted to be. s6.-

eured on the end oia delivery pipe, and lrwhalir 5 Claims. (Cl. 299 141) maybe; termed a retainin m mb rew don to the nipple a. and having ashoulder b between which; and the extremity of the nipple there is clamped; the peripheral portion of a flexible diaphragm; c of suitablematerial, having a central; opening 0 and other openings 0 c 0 and: 0 which will be refer-red to later:

Onthe outer side oi thediaphragm c is a part (1; which; we shall; refer to asa rotatable drum.

This drumis held to the nipple a by means of an inwardly-extending flange b on the retaining: member b, said flange actingthrough ball-thrust bearing eon a collar screwed on to the inner end of the drum d. In, the case of a relatively small nozzle the ball-thrust bearing e may be omitted or, it may be. replaced by a simple ,bear-.

The drum d has a central passage-way d: and, in the illustrated embodiment, six circumferentiallyaspaced passages d d d d 11?; and:- d"; which extend parallel to the central passage 12'. The passages. d and d are turned inwardly at their outer ends and lead at. diametrically-ope posed points into the central passage d as shown in Fig. l. The other four passages. d (1 d and d of the drum. are furnished at their outer ends, as shown in Fig. 2, with removable nipples g each having two small orifices g and p inclined towards one another at a'suitable angle.

If the drum d is rotated to a position in which the passages d and d are aligned with the -open-. ings a and 0. in the flexible diaphragm c, streams of; water flow, along the said passages and on. emerging from. the inwardly-directed outer ends,-

of the passages strike the central jet emerging from the central passage d and break it up. into.

spr y.

If; the drum is rotated to a position in which its passages d d (1 and d are aligned with the, openings 0?, c and c in the diaphragm c-, the passages d and'd are closed and Water flows through the, passages d d d and d to be converted into a very fine mist or fog by means of the: nipples c. There is thus provided around the. central jet emerging from the passages d ashield of mist; or fog which serves to protect the opera.

ator handling the nozzle.

If the drum is rotated to a position in which;

all its passages 'd -d7 are out of alignment with the openings c -c of the diaphragm c a solid central jet only is provided.

The drum dmaybe provided with a handle, hand wheel, projection or projections, or be otherwise suitably fashioned to facilitate its ro-.

ailiqni The flexible diaphragm acts as a seal to prevent leakage through such passages in the drum as it is desired to close, the pressure of the liquid assisting to make the seal. 7

The nipples g are made removable for purposes of cleaning and inspection. In order to prevent clogging of the relatively fine outlets of the nipples a filter in the form of a sheet of fine gauze may be inserted behind each filter as indicated at h in Fig. 2.

An advantage of the construction shown in Figs. 1 to 3 is that a constant outlet is provided through the nozzle even if the spray or fog passages become clogged up.

In Fig. 4 an arrangement is shown in which what we have termed the central opening in the diaphragm and the central passage in the rotatable drum are offset from the centre. In the diagram the openings of the flexible diaphragm are indicated in broken line and those of the rotatable drum in full line. As will be seen from the diagram the rotatable drum can be positioned so that all its passages are closed, the drum thus acting as a shut-off valve. By appropriate rotation the passages (1 -11 can be positioned opposite the openings -0 of the diaphragm, leaving the passage 11 closed and thus providing fog or mist only. In another position of the drum the passage d can be opened up as well as the passages d -d" thus providing a solid jet surrounded by fog or mist.

In still another position the passage d alone can be opened up thus affording only a solid jet whilst in another position the passage 01' and the passages d and d, can be opened up thus affording a spray. The rotatable drum in this embodiment constitutes, as will be seen, a simple shut-on" valve.

If desired, either the spray passages d and d or the fog passages d -d", or the jet passage (1' may be omitted.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
