This inventionhas; relation toj hose-nozzles; and-it'consists in -the construction and novel arran gem ent of a nozzledesigned to be screwed on the freeend of a discharge-pipe, and provided `with large and small water-ways, in combination with a valve to close one when the other is open, for a purpose `hereinafter described. It also coisists in comhining with a nozzle a hinged handle` or` keyand a slotted cap for protecting this key from blows, having stops arranged for the purpose of allowi ing the valve to be opened quickly, and, at

the same time, preventing it from being closed suddenly, and thereby giving an injurious blow to the hose. My invention also consists in the novel Construction of a detachable cap for throwinga spray, and in providing the Valve-case with a screw-seat for holding the cap when not in use, all as hereinafter shown and described. i

In the annexed drawings, the letter A designates my improved nozzle, which is designed to be screwed upon a supply-pipe, and is provided with a small water-way, J, and a large water-way, J', for the purpose of throwing a large and a small stream. B designates a valve-seat of the form of a conical frustum, arranged at right angles to water-ways J J and designed to receive a plug-valve, G, ot'

. corresponding form,'through which are made,

at right angles to each other, orifices D E, one of large and the other of y small size, adapted to register, respectively, with the large and with the small waterways J `J The smaller fln nanr HIS 5 RIGHT "TO HE -ALLEN FIRE' DEPARTMENT SUPPLY' ooM Specifieation foiifihg part of Letters Patent N 70,138, dated Novenber`16, 1875; application fi e i 4 u a -i i Octoher23,1875. A v a i end of valve-plug B is provided `with a eentral polygonal projection, c, which `passes through an opening on the 'correspon'din'g end of the' valve-seat, and is securedthereto by means of a screw, s, passing nto a'threaded recessin the sad'projection, and a washeror nutfl, of suitable shape, whichis passed over e the projectingend of the projection c, and-hears against the end of 'the oasing i or seat, *and thus serves asa clamp for taking up'wear.

The other end of this valve is provided with another projection, b, to which is hinged` or cates `a metallic plate, which is secured 'onthe larger end 'of' the valvecase, and ,coversthe 'operating-handle d, which projects' through sl'ot, s', formedin the' side of `the said cap i for the *purpose- This cap is sufficiently strong to protect -the ogerating-armd from being broken by a casual shock occasioned by.

a fall or other accident, and it is provided upon its under side with an angular downwardly-projecting lug, i, situated intermediately to two similar lugs, ?3 i )rojecting upward from the valve-case, which lugs are designed to act as stops or guides to regulate the discharge of water from the large waterwayJ', and to cut it ofi' entirely from both the small and the large water-ways. will be accomplished in the following manner, to wit: The nozzle beingattached to the supply-pipe by means of a screw-threaded coupling, Gr, on its larger end, if the Operating-lever be thrust to the left to a position just outside of the lug i the small orifice in'the valve will be brought registering with the small eduction-way J in the nozzle, causing a small stream to be thrown. thrust to the left as far as possible the small stream will be instantly cut ofi', and the large one also, ths stopping the flow of water altogether; but if, now, the lever d be thrust to the right, past lugs i 6 i to the opposite end of slot s', the large opening in the valve--plug This a If the said handle be v will 'register-accurately with the large educt J( in the ozzle, and a very large stream Will be produced. Should this stream prove eX- cessive it may be reduced slightly by thIusting thesaidlever to theleft back against lug ?7 more by `thrusti ng it in contact wi th the central-lug i', stili farthei* when moved to lug i',

and finally cut off altogether by causing it to pass the said lug i wherthe very small stream before described as issuing from the small educt J will be restored. i The lugs, as shown in Fig. 3, are of angular form, one face being perpendicular to the length of the slot, and the .other at an -nclination thereto, thus greatly facilitatin g whatever changes may be requisite in the position of lever d for producin'g the above-described streams.

-'It wi11 be 'seen in practice that, the perforations-D E in the valve-O being at right angles to 'each other, itis impossible to have a small stream and a large one at'the same time, as, 'when perforation D is opposite the large .water-way J ',.the smaller Water-way J is' 'cut off-and no water can pass through. The large water-way is to be used in caseof fire, whilethe smaller-vone is intended for the purpose of spink liug the street and washing the pavemenm I; desgnates a rose cap, which is intended' to be 'used for the purpose of throwingasprayfand is designed to be screwed on theend of large water-way J", ahove'described, and'L designates a screwseat *on"` the reduced-end of the valve-case, which'- is-designed to hold-this rose 'when not in use; L'-desi gnatesj a" detachahleannilus,

which is intended tobe screwed on and serve asa' protection to'the screw-seat L when the cap-'L is on-the screw-threaded end of the large way. This annulus and rose are interchangeable, and when the rose is on the large' water-way J' the annnlus may be on the screw-seat and the reverse;-

. Rose I consists of concentric` spaced rings or annuli j, which are each of the general shape of the frusturof a cone, as shown in cross-section, Fig. 1, and are arranged in an inverted position, and are supported from he low by means of diametrical hridge's l l', subtending the screw-threaded rim h, 'so when the stream is turned on 'it dverges in every direction from the center, and spreads over a broad surface.
