TOALL WHOM 4IT MAY CONCERN:

vBe it ltnown that we, MosELY S. CURTIS and GEORGE W. HARRIS, both of the city, county, and State of New York, have invented certain new and useful Improvements in Spray-Nozzles for Hose; and Wed'o hereby declare that the following isa full, clear, and exact description of the same, reference being had to the accom;A

panying drawings, making a portion of this specification, in which-- Figure 1 is a central longitudinals'ectioli of a nozzle constructed according to our invention.-

Figure 2' is .a transverse section of the same, taken in -the line z :v of iig.' 1i. Similar letters 'of reference indicate corresponding parts in hoth figures. The object of this invention isto enable a hose-nozzle -to be employed forthrowing a sprayed or divided stream as'r'equired, for instance, in extinguishing a re withinaroomor in washing windows, and other h similar operations', without preventing the said nozzle from being used when desired for throwing an .unbroken stream in the ordinary manner.

The 'invention consistsin a nozzlo constructed with a series ofpivoted tongues or spurs, so arranged and i operated that they maybe turned inward, over the orifice of the nozzle, to divide the stream issuing therefrom,

or be turned away from the saidorifce to permit theegress unbroken ot thc aforesaid stream, thereby securing the result mentioned, by means of a novel combination ot' partswhereby'the tongues aforesaid may be operated with very great facility; s 1' v l To enable others to understand the construction and operation 4of.our invention, wc will proceed to describe it, with reference to the drawings.

A indicatesthe cylindrical body of the nozzle, which may be attached to the hose in any suitable manner,

Aand the outer end of which may have its orifice, a, slightly less than the inter`ior.of the main length thereof. This part of the body, A, is also diminished extei'iorly, and isformed with a circumferential groove at about the point and which is designed tofreceive the toothed sectors'c, as hereinafter fully set forth. Back. of the groove just mentioned is an external circumferential iiange, el. That portion ofthe body A immediately forward ofthe groove, just hereinbefore described, constitutes as it were a peripberical flange, shown at a', in ig. 2,and in which are formed notches or recesses, whichreceive and form vbearings for the outer ends of stems 5,'the inner .'euds of which work in sockets c', situated as shown at fic. 1, the said steine bein rovided at their central arts e g P P with the toothcdsectors c, working within the hereinbefore-mcntioned groove, as ljust set forth. The outer extremities of the stemsl bhavc provided upon ,them tongues or spurs e, situated nearly or quite at right angles -to' thc said stems, and 'made preferably of curvcdfforin, as slr'own in iig. 2, with their inner edges made more or less sharp. B represents a shell, -tted upon theforward end ofthe body A, and furnished with a shoulder, e-,

which rests against the front side of the angc `d, the said shell being retained in position by an annular-nut,f,

screwed into the innerportion thereof, behind the Hangs, as shown in g. 1. The shell B has an internal annular rib, g, which being in front of the sector c, ctfectually prevents the sam'e from passing out of their places, and is also provided with an internal annular rack, as shown at m, which gears into the toothed sectors.

When it is desired to divide the stream'issuing from the nozzle, the shell B, being loose`upon the body, itis turned partially around in one direction, whereupon the annular rack m, acting simultaneously upon the toothed sectors, turns th'c stems Z", to turn or bring inward the tongues e, over the orifice a, of the nozzle, and in a position radial from the axis of the nozzle, as shown in the drawings,so that as the stream issues'frcin the aforesaidnoricc it will be divided by the s aidtongue, and thus brought into a condition more or l-css resembling that of spray. When it is desired to permit the stream to pass unbroken from the nozzle, the shllB is turned in an opposite direction, to turn back 'the sectors @,and consequently the tongues e, thus bringing the latterl into thopositicn shown in red Outline in fig. 2, wholly away from thc orifice a, thus permitting the uninterrupted passage ofthe stream from the said oriiice.

What we cla-im as our invcntion, and desire to secure by Letters Patent, is- The tongues e, stems bi, and toothed sectors c, in combination with the body A, and the annular raek'm, of the shell B, substantially as and for the purpose specified.

GEO. W. HARRIS.
