NOZZLE FOR HOSE-PIPES.

SPEGTFIGATION forming part of Letters Patent No. 2'78,008, dated May 22, 1883.

Application filed March 14, 1883.

To all whom it may concern:

Be it known that I, 'ljHoMAs HALEY, a citizen of the United States, residing at Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Gontrollingor Shut-Off Nozzles for Hose-Pipes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is an elevation of my improved controlling-nozzle forhose-pipes. Fig. 2 is a vertical section through the center of the same. Fig. 3 is a horizontal section on the line or m of Fig. 2, the position'of theparts being changed Figs. 4, 5, 6, 7, and 8,'.detailsin perspective.

My invention relates to certain improvements on the controlling-nozzle for hose-pipes for which Letters Patent of the United States No. 177,239 were granted to me May 9, 1876.

, The construction of the nozzle described in the aforesaid Letters Patent did not admit of the stream being entirely shut off, but only enabled the diameter of the stream to be changed, and my present invention has for its object to enable the stream to be entirely shut off when required, as hereinafter described.

My invention also has for its object to render the sliding blocks or gates which shut off or control the stream perfectly water-tight when closed together, and take up any wear thatwouldoccasionleakageatthispoint; audit consistsin the combination, with the cap, of an adjustable bushing screwed into the cap in front of the sliding blocks or gates and adapted to be turned by a wrench or other suitable implementto cause its inner end to take a'firm bearin g against the sliding blocks when closed together, and thus take up wear and maintain a tight joint, whereby all leakage is prevented at this point.

My invention also consists in certain details of construction, as hereinafter more fully set forth, whereby leakage between the cap and thread, a, over which fits a corresponding screw-thread on the interior of a movable sleeve,

(No model.)

B, the upper enlarged end of which is bored out, forming a shoulder, I), upon which rests a leather washer or packing-rill g, 0, over which fits a flange, d, on the under side of a ring, D, which is firmly screwed onto the upper end of the portion 10 of the nozzle A, so as to be stationary thereon, the enlarged end of the sleeve B being adapted to turn on the flange d. 1 The ring D is provided on its upper surface.

on each side of its aperture 0, with a segmental through the hose-pipe to entirely shut off the stream of water as required. These blocks 9 g are provided with pins h h, which project into cam-grooves it, formed in the under side of a cap, E, which is provided on its interior with a screw-thread, k, which fits over a corresponding screw-thread on the outside of the upper enlarged end of the sleeve B, and by thus screwing together the cap E and the sleeve B, instead of making a smooth joint and securing these parts together by a series of screws, as described and shown in my aforesaid Letters Patent of May 9, 1876, a much tighter joint can beformed at this point with less labor, and liability of leakage thus avoided, while the operation of puttin g together the nozzle and takin g it apart is greatly facilitated.

Through the outer end of the cap E is formed a circular aperture, m, for the passage of the water to the tip or outer end, a, of the nozzle,

from which it is discharged in a stream of the desired diameter. The tip a is made removable, so that it can be taken off and replaced by another having an orifice of different diameter, and is preferably of a little less interior diameter than that of the lower portion of the nozzle, in order to condense and solidify the stream.

The outside of the cap E is fluted, as seen at p, to facilitate its being turned by the hand, and when the parts are in the position seen in Fig. 2 and it is desired -to shut off the stream, as is often required, it is simply necessary to turn the cap E by hand a quarter of a revolution, which causes the cam-grooves t i to act on the pins h h and bring the blocks or gates together, thus instantly arresting the passage of the water, a quarter-revolution in the opposite direction again opening the gates to their full extent and letting n the stream, and by turning the cap E more or less to increase or diminish the distance between the edg'es 12 of the gates g the force of the stream and the distance to which the water is projected may be augmented or reduced, as desired. When the cap E is turned to shut 0d the water, the blocks g, as they ELI'Q'ClOSGd together, are brought down upon the upper end of the main portion A of the nozzle, the surfaces of the parts in contact being ground to prevent the escape of water laterally into the cap.

The aperture m at the outer end of the cap E is provided with a screw-thread, g, for the reception of a corresponding thread on the out- 'side of an adjustable bushing, G, which is screwed into the aperture m until its inner end projects slightly beyond the inner face of the cap E, so that when the latter is turned to close the sliding gates g together the upper surfaces of the latter are brought firmlyinto contact with the projecting end of thebushing G, thus forming a perfectly water-tightjoint and preventing all leakage and cousequentdamage resulting therefrom; and it will be apparent that any wear of the end of the bushing or the surfaces of the gates can be taken up or compensated for by simply screwing in the bushing by means of a wrench having pins adapted to enter the-apertures r in its outer end, which is readily accessible when the tip a is removed, the employment of this adjustable bushing rendering it easy to maintain a ti ht joint, which would otherwisebe difficult, owing to the y necessity of bringingtheinner ends of the camgrooves i as close as possible tothe edge of the aperture m, to avoid making the cap E of larger diameter than is absolutely necessary.

I What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with the nozzle A, of the movable sleeve B, the-ring D, with its guideways, the sliding blocks or gates g g, having square ends 12, and adapted, when closed together, to entirely shut off the water, the pins h h on the gates, and the cap E, with its cam-grooves i 43, all constructed and arranged to operate substantially in the manner and for the purpose set forth.

2. In a controlling-nozzle for hose-pipes, the combination, with the cap E and the sliding blocks or gates g g, operating as described, of an adjustable bushing, G, screwed into the cap in front of the sliding gates, and adapted to bear thereon at its inner end, substantially in the manner and for the purpose set forth.

8. In a controlling-nozzle for hose-pipes, the combination of the nozzle A, the movable sleeve 13, with its shoulder band washer 0, the ring 1), with its sliding gates g 9, provided with pins h h, and the cap 'E, with its camgrooves t i, and having on its interior a thread, 70, to adapt it to be screwed onto the upper end of the sleeve B, all constructed and arranged to operate substantially as and for the purpose described.

Witness my hand this 9th day of March, A. D. 1883;

THOMAS HALEY.
