NOZZLE Filed July 15, 1929 lm/en "for, faw/ri O- f/al'fer Patented Oct. 6, 1931 PATENT OFFICE EDWIN S. HARTER, F INDIANAPOLIS, INDIANA NOZZLE Application filed July 15, 1929. Serial No;378,311.

This invention relates to the art of nozzles adapted for use in controlling and directing the flow of liquids and may havea number of applications. The invention Wlll be herein I 6 described in one particular application as being employed to control a stream of water such as may be used in washing automobiles and the like. a

The principal objects of the invention re- 1 side in the provision of means ada ted to be held and controlled b one hand 0 the operator; in means com ortably carried n his hand; in means that can be quickly ad usted to hold a given flow and spray of the water; l and in a control means adapted to hold the discharge from the nozzle in a uniformly d1- rected path without causing material vanation from that path at any time throughout the range of adjustment.

Other objects reside in providing a trigger like control without possibility of water leakage and in providing an extremely durable and practical form of a nozzle capable of being manufactured at" a relatively low cost 25 of production.

These and other objects will become apparent in the following description of the one particular form of the invention as now best known to me and as shown by the accompanying drawings, in which Fig. l is a side elevation of a nozzle embodymg my invention with parts of the walls broken away to disclose the inner construction' I Fig. 2, a vertical section on the line 2-2 in Fig. 1;

Fig. 3, a rear elevation of the nozzle; Fig. 4, a vertical longitudinal sectlon through the extreme forward end of the nozzle; and

Fig. 5, a vertical section on the line 55 in Fig.4.

Like characters of reference indicate like parts throughout the several views in the drawings.

I form a casting with an upper horizontally disposed barrel from which pro ects downwardly and rearwardly an intercommunieating barrel 11 of a diameter adapted to be 50 comfortably held and gripped by an operators hand. The lower end of the barrel 11 has an internal screw-thread 12 adapted to receive therein the end of a hose (not shown). Near the upper end of the barrel 11 and immediately under the barrel 10, a finger ring 13 is secured on the rod 14 horizontally sliding into a tube' 15 integrally formed with and horizontally extending across through the barrel 11. The other end of the rod 14 is screw-threaded to receive thereon the adj usting nut 16 and at its extreme end the upturned bracket 17. A guard 18 extends horizontally from the rear side of the barrel 11 below the rod 14 and the nut 16 thereon.

On the front end of the horizontal barrel 10 is screw-threadedly engaged the nozzle 19 having a bore 20 in its end substantially equal to the bore of the barrel 10 and having a bore 21 of a greater diameter than that of the bore 20. piston 22 is slidingly carried within the bore 21 and has a connecting rod 23 extending rearwardly therefrom through the barrel 10 to be engaged by the bracket 17. A packing nut 24 through which the rod 23 passes screw-threadedly engages with the rear end of the barrel 10 to provide a water tight fit around the rod.

Within the bore 21, a compression spring 34 bears against the piston 22 and the shoulder 25 at the forward end of the barrel 10 so as to carry the piston 22 normally toward the front end of the bore 21. The piston 22 is provided with a plurality of holes 26 therethrough, here shown as six in number, Fig. 2. The bore 20 Within the nozzle 19 is reduced at its front end to form a valve seat from the rear side. to leave an orifice through which the needle 27 may be passed.

Referring to Fig. 4, this needle 27 has a forward conical end on a neck 28 reduced in diameter and carried by the flared compression member 29 which may be pressed against the seat in the rear of the orifice 30 to effectively shut off all flow of fluid therethrough. The needle 27 is roekably supported on the forward end of the bar 31 by means of the post 32 being loosely carried into the hollowed end of the bar and there retained by the transverse pin 33 extending through a hole in the post 32 and held by each end in the bar 31. The pin 33 is of a diameter reduced considerabl from that of the hole in the post so that e needle 27 is free to be rocked angularly about the end of the bar 31. 5 The device may be held by gripping a hand about the barrel 11 muc as a piston is gripped, and the index fin er is inserted through the ring 13 to ull the rod 14 backwardly to in turn pull t e needle 27 back out of the orifice 30 b overcoming the compression ring 34. e amount the ring 13 is pulle? toward the barrel 11 will determine the quantity of water discharged through the orifice 30 and also the character of the spray.

By positioning the needle 27 longitudinally in reference to the orifice 30, a discharge may be effected in the form of a fine mist, a fine stream of considerable velocity or a larger stream of lower velocity, with any variation therebetween. B reason of the fact that the needle 27 is rocka ly held on the end bar 31, the needle will automatically be centered in i reference to the axis of the orifice 30 by the flow of water-therearound and therepast so u that even though the bar 31 be slightly removed from the axial center of the bore 20,

the needle 27 will be automatically retained centrally of the orifice 30 to give a discharge of uniform distribution in respect to all angles therearound.

While I have here shown and described my invention in one particular form, it is obvious that many structural changes may be made from that form without departing from the spirit of the invention, and I do not desire to be limited to that precise form any more than may be required by the following claims.

I claim:

1. In a nozzle,a liquid supply barrel serving as a hand rip, a second barrel in communication wit and extending at an angle from the first barrel, a nozzle on the end of the second barrel, a valve needle within the nozzle, a rod slidingly carried transversely of said first barrel, a second rod axially extending through said second barrel and into said nozzle, means interconnecting said rods, said needle being carried axially by said second bar upon travel thereof, and spring means normally returning said needle to close said nozzle, said interconnecting means being without both barrels, and an adjustable stop on said rod between said first barrel and said interconnecting means.

2. In a fluid control nozzle, a valve seat, a needle having var ing diameters adapted to be inserted throng the orifice defined by said seat, a shoulder on the needle adapted to contact said seat and close said orifice, a rod adapted to be moved axially of the nozzle having a hollow end, and means loosely engaging said needle with said rod comprising a reduced end of the needle carried into the hollow end and a transverse pin extending Q! through a hole in said reduced end whereby said needle may be centered within the orifice by the flow of fluid therepast.

3. In a fluid control nozzle, a valve seat,a

needle having va ing diameters ada ted to be inserted throng the orifice defined y said seat, a shoulder on the needle adapted to con-' having a hollow end, and means loosely en-' gaging said needle with said rod comprising a reduced end of the needle carried into the hollow end and having a transverse hole, and. a pin much smaller than the hole seated in the rod and extending loosely through the hole whereb said needle may be centered within the ori ce b the flow of fluid therepast, said valve seat ing tapered inwardly toward said orifice to aid in guiding said needle theretoward.

4. In a fluid control nozzle, a valve seat, a needle having varying diameters ada ted to be inserted through the orifice defined y'said seat, a shoulder on the needle adapted to contact said seat and close said orifice, a bar adapted to be moved axially of the nozzle,

for pulling said rod rearwardly to overcome I 'sa1d spring, and stop means associated with saidrod and trigger means for selectively holding said rod against the pull of said spring.

In testimony whereof I aflix my signature. I

EDWIN S. HARTER.
