IMPROVEMENT IN HOSEI-PIPE NOZZLES.

Specification forming part of Letters Patent No. 173,388, dated February 15, 1876; application filed June 1s,1s75.

To all whom it may concern:

gBeit known that We, JAMES D. GARMODY and ALEXANDER CRAWFORD, both of Evansville, Indiana, haveinvented a Hose-Pipe Nozzle, of which the following is a specification:

The object of our invention is to make an improvement inturning on and shutting off circuitous course of the water is produced by means of stopping up the bore of the nozzle between the ports b-andthe'ports b,and by means, also, of the revolving conductor E,

Fig. 2, which has water-ways in its interior,

as shownin the sectional views of the same, Figs. 4. and 5. The water-ways c in the re- .volving conductor have their months or ports so constructed as to correspond to, and form communication with, the ports I) and b whenever it may be desired to throw a stream of water, by simply turning the revolving conductor with the hand andcausin g it to revolve on and around the nozzle on which it is placed as a ring,'and held to its place by the milled nut, Fig. 3, screwed onto the nozzle atd, Fig.

1. The revolving conductor fits'the nozzle over the ports I) and b, as shown in Fig. 4,

where it turns on the nozzle and forms with it a ground joint. Fig. 5 is a sectional view of v the revolving conductor, cut across its waterways at the place indicated by the line a- .z', in Fig. 4, which is a longitudinal sectional view of the nozzle, Fig. 1, and shows, also, cut at right angles to the sectional view in Fig. 5, a sectional view of the revolvingconductor with its water-ways 0 so turned as to correspond to, and communicate with, the ports I) and b. The arrows indicate the course of the water as it enters the nozzle, passes out of the nozzle, through the ports b into the revolving conductor along the water-ways c, and back through the ports 7) into the barrel of the nozzle, and out. By causing the conductor to make part of a revolution the mouths of the water-ways c are carried past the ports I) and b, with which they approximate, as shown in Fig. 5, and the water is thereby shut off. It is let on by again turning the-conductor so that its water-ways correspond with, and open into, saidports in the nozzle.

We claim as our invention 1'. The nozzle A, Fig. 1, made with the two sets of ports I; and I), and the barrelof the nozzle permanently closed between said ports and made in one piece.

2. The combination of the nozzle A and the revolving conductor E, Fig. adapted thereto, as and for the purposes described."
