NOZZLE Filed March 6, 1930 CIJ Patented Dec. 8, 1931` UNITED sixres PATENT FRED E. HANsnmoF CLEVELAND, OHIO'4 1 NozzLn ture but this arrangement has been unsatisfactoryl because there was no pressure in the passageV and after the valve was opened, the

Huid had to traverse ,the passage to the aper-' ture beforeany fluid could be discharged. Furthermore, when the valve was closed, iuid remained in the passage, which could drip out and waste, as Well as 'spread over the surface of the device to interfere with handling thereof.

It is therefore an object ofthe present invention to provide a device of this character with a valve at the extreme end of the discharge passage, whereby the passage may be full of iluid'under pressure, resulting in .instantaneous i'ow when the valve is opened, and no passage is left beyond the valve to v contain fluid and cause-undesirable dripping when the valve is closed. c I f Another object is to providev a simpleand convenient remote control means for the nozzle valve. Y A further object is to provide a swiveled nozzle having an angularly disposed, discharge end, with means for operating the valve in any position of the angularly disposed end.

Otherobjects of the invention and features of novelty will be apparent from the following description `as taken in conjunctionV with the accompanying drawings, in which: v

Fig. 1 is a longitudinal section through a nozzle of the-character described, according to the preferred embodiment ,of the presen invention; l

Fig. 2 is an elevation of thev structure. shown in Fig..1; f

Fig. 3 is an enlarged longitudinal section of the tip portionofthe structure;

Fig. 4 is a transverse sectiontaken alongl .theline 4-4 of Fig. 1; and

Fig. 5 is an enlarged Vthe remote control mechanism for the` nozzle valve. i V 1 Referringvmore Yparticularly to 'detail' of parts of f ,15,65 ,Y ,the drawings, the nozzle comprises abody member "10,

a handle 1,1, a conduit member l2 and a nozzle tip 13.v The vbody member and handle 11V serve to -connect ,the conduity member .12

as vthe flexible supplyhosenlfl. AThe :handle 11 forms a gripcbywhichfthe jet from fthe nozzle trip 13-may be directed.v

The body memherlOA is preferably. a hollow T-shaped casting swivelly'fconnected as yat 15 tothe `conduit member 12. One branch of y, 6o with a source of fluid under pressure,fsuch y the T is threadedlyconnectedjas at 16j-with V Va collar17. A flanged member 18 is carried by the conduit 12, the flangev19 thereof being rotatably received ,between the, v'end'v of the threaded portion 16 and the flange 20.1of the collar 17 thusforming the desired swivel;

The opposite branchv ofthel memberffl() is threadedly connected as Iat 21 with the hollow cylindrical handle 11, the outer end of which has a threadedconnection 22.130 receive the coupling for thehoselea i I One end of a helical spring 23 abuts a shouldertV in the bore ofthe handle l1, and the other end thereof urges a ring member 25 against the end of the-threadedv portion 21. ,Y Thel ring member 25 Vcarries a conical screen 26,*the'apex of which is Adirected toward the source of a fluid supply. under pressure. Onthe other side of thering 25 there is ay ring 27 which engagesa'discscreen 28, and the spring 23 also serves to hold. thedisc screen 28 between the flange 27 andfan in- ,ternal` shoulder 29V of Vthe `bore infthe body portion 10.

A lateralr of which vslidably receivesl a stem 32 having y .an operating head 33, af spring 34 bein yinfterposed between the plugv31 andthe f4 ead so Y` n branch :Tv member .,threaded'to receive a bored plug 31,V the bore 33. The innerend of thefboreis enlargedand tappedas at`135 toreceivea lp aclril'ig V36y and nut 38', thusA lforming astufIingboX-for the slidablestem ,32... The Yinner endof 1' stem `32 has a head 87 which co-operateswith a part of the control mechanism to be later described.

The liquid conduit member 12 comprises a pipe which is bent intermediate its ends as at 88 and, by virtue of the swivelv15, the member 12V maybe rotated relative to the/body 10 to project the liquid jet in dierent directions from the end of the nozzle and thus permit ting the member 12 to be so positionedas to enable the device to be held in a convenient position in directing the jet into parts or f inbefore referred to.

regions whichmight otherwise be diiticult of access. Beyond the bent portion 88 the conduit member 12 terminates inthe tip 13 here rlhe tip comprises a .threaded cap 39 having al thin outer wall 4() in which is provided a very small aperture 41, which Jfor-'ms the orifice through which the jet is projected.

Y 'A valvemember 42 is mounted inside the wall 40 and is provided with a washer 43 'adapted to engage the inner surface ot the wall 40 andy complet-ely close the aperture 41. Thejwasher 48 is received within a recess formed by the tlangev44 on the valve member 42. Themember 42 isV of polygonal cross section as shown at4`5, toallord passages for the fluid around the valve member.

A helicalY spring 46 normally urges the valve member 42 into position to'close the 'aperture 41. VThe inner end Vof thesprin y is enlarged to receive a packing 51 and a ygland nut 52 which is sleeved on the member V12 and has a threaded engagement with the Jtipia i f Y For operating the valve 42 by means of the control head 33,' a preferably flexible'element `54 carriesa loop 55 at its' outer end which is arranged in a bore 57 in the valve 42 and attached 'to a. pinV 56 carried by the valve 42. The llexible element 54 extends through the Inei'inber 12 and the swivel connection 15 and intothe body member 10. Y

The innerend of the flexible element 54 is connected to a trigger member 58 by means 'of which the same may be operated tromv the fcontrol head 33. rIhe member 58 comprises cupportion 59 having a flange 60 of slight-- lyV smaller' diameter than the internal bore of the member 1.0,' and adapted to rest against 'the inner end of the member I12. VThe cup portion 59 isprovided with a' plurality of holes 61, and a pin62, which receives a loop 'end 63 "of the l'flexible control element'54. In-

tegral with the cup yportion 59V is an arm 64 which is formed as a surface of revolution and' engages the head 37;

Y In operation, assuming that the threaded connection 22 has been made with the source of fluid underrpressurey in the hose 14, the liquid .will lill the bore of the handle 11, pass* ingjthrough the conical screen y26 and the secondary disc screen 28, and will also till theY interior of the body member 10. The holes `61 permit the liquid to till the member 12,`and the space around the valve 42, being prevented from escaping through the orifice 41 bythe valve. The device being graspedby the handle 11, the same may be directed as desired and by virtue'of the swivel 15 the bent outerend ot the conduit member 12 may be turned to direct the jet in the desired direction. The head 38 may be ldepressed bythe thumb of the hand grasping the handle 11, causing the trigger 58 to be tipped about the point 65 on the flange 60, which fulcrums on the shoulder formed by the inner end of the member 12. Thus a pull is exerted onV the flexible element 54 Whichwill draw the valve 42 away from the cap SQ'and permit the liquid to flow through the orifice 41. By virtue of the'sur'tace of revolution provided on the arm 64 this action will bev the same forvall Vpositions of adjustment ot the member 12. v

Release Vot the head 33 will p'ermitfthe spring 46to effect reverse operation ofthe parts and close the valve 42, the spring 84 serving to restore the head 38 to its original position. The tip l13 may berotated to accurately position the wall 40 injengagement withthe washer 43,L and locked, in any position to which it is adjusted, by means of the nut 52. i Y

' From the foregoing description it Will beV apparent that the present invention pei'- inits the entirel` device/to be Vfilled with liq uid under pressure, andfcauses instantaneA ous projection of a full jet as soon asthe valve is opened, inasmuch as the valve for controlling the -tluid is located at the orifice of the nozzle tip. It isalso Vapparent for the same V reasons that when the valve isclosed, the jet is cut ott'instantaneously,,and there are no passages beyond the valve to retard' or delay the jet, or accumulatetlui'dr causeV undesirable dripping.

hile one embodiment of the .invention has been illustrated and ldescribed in sufcient detail to enable any one skilled in iications may be resorted to Without departing from the spirit of the invention.
