HOSE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 553,999, dated February 4, 1896.

Application filed February 11,1895. Serial No. 537,861. (No model.)

To all whom, it may concern:

Be it known that I, HENRY NIOHOLSBURG, a citizen of the United States, and a resident of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Hose-Nozzles, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts in all the figures.

This invention relates to hose-nozzles, and has for its object to provide a simple, cheap, readily-constructed, and perfectly-operating device by means of which a single movement of a lever, rod, or the like will open said nozzle, a further movement thereof cause the same to spray, and a third movement, preferably independent of said lever, will wholly close said nozzle, a further object being to provide such a device as may be operated wholly by one hand.

The invention consists in the novel construction and arrangement of parts, whereby the above-mentioned and other desirable results are attained, and hereinafter fully de-' scribed.

Referring to the drawings, Figure 1 is a longitudinal vertical section taken through the exact center of a device embodying my invention. Fig. 2 is a similar horizontal cen tral section. Fig. 3 is a transverse section upon the line m 50, Fig. 1.

In the practice of my invention I form the nozzle A with an annular flaring central portion A, within which is a transverse angular, preferably integral, partition A comprising a horizontal valve-seat A, provided with an aperture to. At the forward end of the nozzle is a flaring mouth B, interiorly conical, having upon the rear thereof an externally-threaded flange 1), within which is an inwardly-projecting flange c, said mouth being removably screwed in the end of said nozzle. Upon the rear end of the nozzle are formed a plurality of annular projections or flanges d,frusto-conical or tapered rearwardly to form projecting shoulders (Z.

In the roof of the center portion A is mounted a vertical plunger or rod 0, preferably working in a bushing e, removably screwed into said roof with an intervening washer e. The lower end of the plunger 0 is tubular or apertured to receive therein a spiral spring D, which projects also into a recess f, formed in a cylindrical plug E, screwed into the base of the nozzle, and provided with an annular flange g, between which and the base portion is a washer g.

Mounted upon the plunger 0 below its center and bearing against the under surface of the horizontal valve -seat A is a flexible washer F, above which the periphery of said plunger is upwardly tapered, and provided with an annular shoulder h. Slightly above the shoulder his an upwardly-flaring or conical annular projection c', the top of which forms a second shoulder, immediately above which is formed a projection or flange 1; of appreciably greater diameter than the width of the rod above the shoulder h. Upon the top of the plunger is a removable disk or head 0, by means of which said plunger is depressed, the same being maintained normally raised, and the valve F closed against the seat A by means of the spring D within the recess f and the lower end of the plunger 0, which said end normally projects partially into said recess.

Mounted in spider-bearings j, secured in the forward portion of the nozzle A, is a rod or bar G, having an elongated vertical slot is therein, through which extends a pin or bolt is, inserted through the upper surface of the nozzle and screwed into the under surface thereof, whereby longitudinal movement of said bar is permitted, but limited. The forward end of said bar is appreciably reduced in diameter and provided with a conical annular head Z, adapted to fit within the flange 0 formed in the mouth B to approximately close said mouth, the rearof said head Z forming a shoulder Z, which the liquid passing through the nozzle strikes when said head is projected beyond the flange c. Betweensaid flange c and a flange 0 upon the bar is coiled a spiral spring H, the tendency of which is to retract the bar G. extreme rearward movement thereof. Upon the rear end of the bar the edge thereof is downwardly beveled or inclined and curved or provided with a slight vertical groove to The flange c limits the engage or clasp the plunger C. Upon one side the said end of the rod G is cut out to form an inwardly-beveled edge m, rearward and inward of which is a parallel edge m" with an intervening shoulder m which said edges and shoulder are formed by vertically recessing or notching the side of the bar.

Sliding transversely in the side of the nozzle A, which faces the recessed side of the bar G, and extending through a removable buslr ing '22, screwed into said nozzle, is a rod I, having a conical annular head 0 upon the inner end thereof, adapted to engage the beveled or inclined faces in m, and upon the outer end thereof is a disk or head 0 for actuating said rod, intervening between which and the bushing 11 is a spiral spring 2).

The operation of the device will be readily understood from the foregoing description, taken in connection with the accompanying drawings.

The nozzle is normallyin the position shown in the drawings, the plunger C being raised through the agency of the spring D and the bar G extended forwardly against the spring II by reason of the diameter of the red at the point of contact thereof with the rear edge of said bar. It being desired to open the nozzle, the plunger C is depressed by bearingupon the disk C until the shoulder h is immediately beneath the bar G, whereupon the spring II will retract said bar against the reduced portion of the plunger. This movement of the plunger opens the valve F and permits the free flow of the liquid through the nozzle, while the retraction of the bar G draws the head Z inwardly and opens the mouth B, whereupon the greatest flow of the nozzle is had. On further depressing the plunger the flaring projection i bears upon the beveled edge of the bar G and extends the same against the spring II, thereby projecting the head Z beyond the flange c, and when the said projection 1' passes the under surface of said bar the projection or flan ge i prevents retraction of said bar. As the water flows through the flange c, it strikes the shoulder l of the head Z, and, particularly in conjunction with the flaring mouth B, the nozzle is caused to spray, and the force of the flow is increased by the further depression of the valve f.

\Vhen it is desired to close the nozzle, the head is pressed, thereby forcing the rod I inwardly, and if the bar is retracted beyond the position shown in Fig. 2, as when the mouth of the nozzle is wholly open for free flow, the conical head 0 will engage the beveled face on and force the bar forwardly to disengage from the shoulder 72, whereupon the spring D forces the rod 0 upwardly and closes the valve, the nozzle being then returned to its normal position; and when the bar is extended beyond the position indicated in Fig. 2 by contact with the flange z" said head 0 engages the face 771 and still further extends said bar to release the plunger 0, as

before. The spring 1) maintains the rod I normally out of contact with the bar and in position for engagement with either of the faces.

It is to be noted that the flanges (Z forming the shoulders d upon the rear end of the nozzle permit the same to be inserted in the end of a rubber hose and secured thereto without other fastening or screwing. Furthermore, the construction of the nozzle is such that the whole may be formed of a single casting, and the mouth B, the plug E and the bushings c and n very readily removed, as for cleaning and repair.

The advantages resultant from the use of the invention will be manifest to all who are conversant with the general class of devices to which the same appertains.

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

1. In a nozzle the combination with a valve adapted to open and close the same and a depressible plunger arranged to actuate said valve, said plunger being normally raised, of means for holding said plunger in the depressed position and a button engaging said holding means and adapted when pressed to release the plunger therefrom, substantially as described.
