FLUID DIgcHARGE DEVICE f Filed sept.' 14, 1940 Simpy f7@ on Patented Nov. 24, 1942 UNITED STATES PATENT OFFICE y FLUID DISCHARGE DEVICE Shung Moon,lRiver Rouge, Mich.

14, 1940, serial No. 356,843 1 claim. (c1. 251-24) Application September This invention relates to the class of sprinkling,

spraying and diffusing and pertains particularly to improvements in sprayer devices designed primarily for use in moistening clothes preparatory to ironing. Y

The primary object of the invention is to provide a novel compact sprayer head or nozzle which is designed to be attached to a hose to receive water directly from a domestic water supply system, the nozzle being so designed that the application of pressure upon an element thereof releases a -valve diaphragm which permits the water to shift the diaphragm from its seat and dow through for discharge from the nozzle tip.

Another object of the invention is to provide a spray device wherein a head, provided with a diffusing nozzle, carries a shiftable diaphragm which is normally maintained upon a seat by a hand actuated handle, said diaphragm when rey leased by the actuation of the handle being shifted from its seat to permit water under pressure to pass through the nozzle for discharge from the tip in the form of a fine spray.

A further 'object of the invention isto provide a spraying device of the character stated wherein a novel means is provided to facilitate` the ready adjustment of the degree of neness of the water spray discharged from the nozzle.

The invention -will be best understood from a consideration of the following detailed descrip,- tion taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not to be confined to any strict conformity with the showing of the drawing but lmay be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claim.

In the drawing:

Fig. 1 is a top plan view of the sprayer embodying the present invention.

Fig. 2 is a sectional view'on the line Fig. 1.

Fig., 3 is a View in elevation of the rear end of the sprayer. Y

Fig. 4l is a View partly in section and partly in side elevation of a modified form of the sprayer.

Referring now more particularly to the drawing, the numeral I generally designates the body or head of the spray device embodying the presi ent invention. This body may be cast or otherwise suitably formed of any suitable material andV it is provided with a tapered vforward end portion 3 provided to facilitate the' attachment to the head of a hose or other suitable conduit 4 by means of which water may' be 'conveyed from a water supply system to the. nozzle.

In the rear of the nozzle body there is formed v nozzle 1 and this taper is made use of for securing in position in the forward end of the chamber 6, the core 9 which functions to impart a whirling motion to the water as it issues from the nozzle aperture 1. Thisbody 9 is formed of a relatively soft metal such as aluminum or brass and the side surface is provided with the plurality of spiral grooves or channels Ill along which the water ows in passing between the body 9 and the tapered portion 8 of the water chamber wall.

The degree of neness of the spray issuing from4 the nozzle 1 may be controlled by regulating the extent 4to which the spiral core body is forced into the tapered end 8 of the water chamber, it

being readily obvious that as the core body is forced into the taper, it will be mashed or compressed and will reduce the size of the spiral grooves or channels. Thus the farther the core bodyfis forced into the taper, the ner will be the water spray issuing from the nozzle 1. A l

The nozzle passage 'I is protected from damage through the tip of the body being struck against objects, by being set back in the tip, and the end.

l provided an annular seat I3 -for'a valvev disk I4 formed of rubber or other suitable material. This valve disk is maintained in position adjacent to the seat I3 sovthat the portion adjacent the seat may have limited movement relative to the seat 'permitting it to shift off of the same, under the effect of water pressure applied thereto, the re-v tention of the diaphragm being effected by the ring I5 which is secured -to the .Wall of the recess either by a press fit or by screw threads,

2 and at its rear with the integral coupling nipple 55 as shown.

Extending throughY and from the nipple 3 is a water passageway I6 which at its forward end is reverted, yas indicated at I'I, to open into the bottom of the annular water channel I2. Since the overall diameter of the water channel I2 is less than the diameter of the recess and of the valve disk Il, it will be readily seen that the valve disk or diaphragm when 'pressed against the seat I3, will effectively close the channel.

' Extending longitudinally in the top of the body I is a slot I8 across the rear end of which a pivot pin I9 is secured. The rear end of this slot is in communication with the annular recess 5 and there is disposed within the slot the handle which is pivotally supported upon the pin I9 and which has the laterally turned rear end portion v ascenso tent to which the plug is forced into the tapered 2| which terminates in the reversely extending l linger tip 22, which is disposed substantially upon the axial center of the water chamber 6. Thus the linger 22 will be disposed at the rear of the center of the diaphragm valve and when the forward end of the handle is raised to oscillate the handle on the pin I9, the linger 22 will move toward the diaphragm.

Interposed between the nger 22 and the diaphragm is a disk 23 of metal or other suitable material which functions as a 'bearing plate against which the nger engages whenthe handle is oscillated in the proper direction to move the finger forwardly for the purpose of pressing the valve diaphragm against the seat I3.

Constant application of pressure against the disk 23 and diaphragm Il by the finger 22 is effected by placing a suitable expansion spring 24 beneath the forward end of the handle 2U, locating the ends of the spring in the opposed recesses 25 and 26 formed respectively in the handle and in the body. By this means, the spring is retained in position and can function freely to oscillate the handle in the desired direction to maintain the valve diaphragm upon its seat.

From the foregoing, it will be readily apparent that with the spray device of the present invention, a constant supply of water under pressure can be kept ready at hand for discharge in a ne spray over clothes or other objects and when the spray body is taken in the hand and pressure is applied to the handle 20, the diaphragm valve will be released so that it is free toshift from its seat. This permits the water to force its way from the channel I2 past the valve and into the chamber 6 to flow forwardly and be discharged through the nozzle .'I.. As previously stated, as the water passes the spirally grooved plug 9, it will be given a rotating motion and will forward end of the chamber. A

While there has been shown a nipple 3 which is cast or otherwise formed integrally with the body I, it is to be understood that there is no desire to limit the construction of the spray evice to this specific design and it will be read ly apparent that other means may be employed f r attaching va hose or other fluid carrying pipe o the head as, for example, as shown in Fig. 4. the body may have a short tube 21 inserted thereinto in alinementI with the water receiving passage which is here indicated by the numeral I6', which will function in the place. of the nipple to be coupled with a hose or other fluid supply pipe.

What is claimed is:

A fluid discharge device, comprising a body having a forward end portion and having a water, chamber extending. longitudinally therethrough and communicating at one end in one portion of the body with an outlet, the body being provided at the opposite end of the water chamber with a recess into which the water chamber opens, the bottom of the recess being provided with an annular channel encircling the chamber, the material of the body between the channel and the water chamber forming an annular valve seat, means for conducting iiuid into the annular channel, a diaphragm valve disposed in the recess over the channel and said seat, means engaging the diaphragm at its periphery for establishing a water-tight connection between such periphery and the wall of the recess at the outer side of the annular channel, a slot formed longitudinally in the side of the body and extending across but spaced from the outer side of the channel, the slot leading, at the end remote from the outlet, into the recess upon the side of the diaphragm away from said outlet, a handle disposed within said slot and pivotally supported for oscillation on an axis extending transversely of the body, the handle at one end having an inturned portion lying in the said portion of the slot leading into the recess, a lingerextending from the inturned portion of the handle toward the'center of the diaphragm, a pressure receiving element interposed between the finger and the diaphragm, and resilient means lyingin the slot beneath the handle and constantly urging oscillation of the handle in a direction to move the said ngertoward the diaphragm to elect compression of the same against the seat.
