The purpose of this invention is to provide an improved and simplified construction of a spray nozzle for discharging a stream of water with wide distribution over the area within its range, avoiding the common defect of so-called spray nozzles that the stream is almost wholly diverted from a central area surrounding the position of the nozzle. lt consists in the elements and features of construction shown and described as indicated in the claims.
ln the drawings:
Figure 1 is a, side elevation of a spray nozzle embodying this invention.
Figure 2 is an axial section of the same.
Figure 3 is an axial section of the two body members unscrewed from each other and shown on a large scale, and a valve stem in the form for entering the aperture in a bridge in which it is eventually secured by upsetting or riveting over the end.
Figure 4 is a plan view of a spider which constitutes partial means for limiting the unscrewing of the two body members which might otherwise occur in the adjustment of the nozzle for range of spread.
Figure 5 vshows a split ring snap spring which cooperates with the Spider for the function stated.
The spray nozzle shown in the drawings comprises two hollow body members, A and B, screwed together, the member, A, be1ng interiorly threaded at the larger end for coupling to a water distributing pipe as a hose pipe, and may be referred to asthe rear or base member. The member, B, 'is exteriorly threaded at the rear end for screwing into the interiorly threaded forward end of the member, A, and at its forward lend comprises the widely flared discharge mouth of the device. This member may be referred to as the forward body member. This forward member is constricted as to its cavity intermediate thev ends, forming a limited fluid port, 10, and a rearwardlyfacing valve seat, 11, back of that port, while forward of the port the cavity is expanded v at a wide angle,more. than 90 as shown,-
constitutin a flaring discharge mouth for wide distri ution of the shower which it is the purpose of the construction to deliver. The rear member, A, has rigidly mounted in a bridge bar, 12, with which said member is*l provided, the valve having its stem, 15, reduced at the end to form a shoulder, 15 flxe'd ani longitudirlly stopped in both directions in said bridge bar, by said shoulder and theupset or riveted-over end, 15b and its head, which is tapered ata wide angle, seating on the seat, 11. The valve has an extension, 13, protruding through the port, 10, and terminating in a slight enlargement, 16, which has the function of assisting in deflecting outwardly the water which derives an oblique angle of discharge in passing between the tapered valve head and the correspondingly tapered seat, causing the stream to take the form of a hollow cone lining the conically flared mouth.v At
the extremity of this flaring mouth there is formedA a slight inwardly projecting lip, 20, which has the purpose and effect of deflecting a limited portion of the wide spread discharge back inwardly for covering the central part of the area within the annular zone covered by the remainder of thestream deflected at the Wide angle of the flaring mouth. y
It will rbe understood from the foregoing description that the nozzle is opened by unscrewing the member, B, from the member, A, extending the over-all length of the xture, and moving the seat ofthe valve away from the valve; and that the nozzle is closed by screwing the member, A, into the member, B, moving the seat of the valve down onto the valve, diminishing the" over-all length of the fixture. In the absence of preventive means it will be seen that there will be liability to entirely unscrew the member, B, from the member, A, in the adjustment for opening the nozzle and adjusting it. This liability is avoidedr by the provision of a spider, 21, fitted for sliding on the stem of the valve back of the head, and diametered as to its three arms, 21, for spanning the cavity of the member, B, back of the constriction in which the`port and valve seat are formed; and providing for co-operating with this spider a split ring snap spring, 22,/ which is snapped into an interior annular groove, a, formed near the inner or lower end of the member, B, the' diameter of the wire of which this ring is formed being greater than the depth of the groove, so that the wire projects into the cavity of the member, B, back of the ends of the spider arm, and serves as a check or stop for the spider, preventing it from escaping from the cavity of the member, B, and preventing the member, B, from being withdrawn unless enough force is applied for unscrewing said member from the member, A, to crowd the snap spring out of the groove.
I claim:
. 1. A s ray nozzle having its discharge terminal urnished with a widely tapered smooth mouth forv spread of the spray and a water inlet thereto substantially axial with respect to said mouth, said mouth being finished at its outer margin with a slightly inturned ange, whereby the outermost portion of the spread stream is deflected inward for covering the central area from which the discharge is diverted by the spreading means of the nozzle including said widely tapered mouth.
2. A hose discharge nozzle comprising two hollow members screwed together, the forward member having an inwardly facing valve seat, a valve carried by the rear mem ber and longitudinally stopped therein, and having its head adapted to co-operate with said inwardly facing seat for closing the water passage, and co-operating means on the valve stem and the forward member for stopping the o ening movement of the valve; whereby t e valve member constitutes means for preventing the unscrewing of the two hollow members from each other, said co-operating means comprising a spider slidingly fitted on the valve stem and rigidly dimensioned for spanning the axial cavity of the nozzle, the latter having toward the inner end of the forward member an internal groove, and a split ring spring sprung into the groove behind tlie spider.
In testimony whereof, I have hereunto set my hand at Chicago, Illinois, this 3rd day of February 1926.
