WATER-COCK.

SPECIFICATION forming part of Letters Patent No. 651,289, dated June 5, 1900.

Application filed M h 8, 1900. Serial No. 7,846. (No model.)

T0 at whom it may concern.-

Be it known that I, JAMES P. BENTON, of Dalles, in the county of Wasco and State of Oregon, have invented a new and useful Improvement in Water-Cocks, of which the following is a specification.

My invention relates to water-cocks and faucets, especially those which are intended to be used for outdoor purposes; and it has for its object a construction of device of this character whereby the automatic bleeding or venting of the water out of the stand-pipe may be easily and surely effected without siphoning the water in the hose back through the stand-pipe and also whereby the actuation of the bleeder will be'caused by the stand-pipe itself instead of by keys, thereby bleeding or venting the stand-pipe every time the water is shut 01f.

The invention consists in certain details of construction and arrangements of the parts, which I shall hereinafter fully describe and claim.

Reference is to be had to the accompanying drawings, in which- Figure l is a vertical transverse section of a water-cock embodying my invention, and Fig. 2 is adetailperspective of the piston and its valves.

Referring to the drawings, A designates the body of the bleeder, adapted to be secured by a lateral nipple to the water-supply pipe A and formed with a discharge-passage D. B designates the cock, of any approved construction, provided with the opening O,adapted to be brought into communication with the opening in the supply-pipe in the usual manner and having a port E registering with the discharge-passage D when the water is shut off. In the upper end of the cook B screws the stand-pipe F, which has screwed onto its upper end the fitting G.

The fitting G is formed directly opposite the dischargepassage in the stand-pipe F with a vertically-disposed opening or bearing G, and a tubular piston R is fitted to movev in such bearing, as shown particularly in Fig. 1. The piston R has a lower screw-threaded end, on which the valve J fits, said valve being held against upward displacement on the piston by the washer K and being adapted to rest on the seat I when the water-pressure is oif and on the seat T when the pressure is on. In the lower end of the piston R is fitted the triangular stem P of a puppet-valve O, which has movement in the cage L, the latter being provided with legsor guides M and a crossbar N, as shown, and secured to the piston R below the valve J. The puppet-valve 0 moves up against the scat L in the cage and closes the lower end of the piston R when the water-pressure is on, but drops to the crossbar N when the pressure is oif.

The operation of my invention is as follows: WVhen the water-pressure is on in the stand-pipe F, the valve J will rise, carrying with it the piston R, the cage L, and the puppet-valve 0, thus closing the space around the piston at the seat T and also the passage through the piston. When the water-pressure is turned off, the piston R and its concomitant parts will drop, with the valve J resting on the seat I and the puppet-Valve 0 dropping to the cross-bar N, thereby shutting off communication between the outlet of the fitting and the stand-pipe and allowing air to enter through the piston in the direction of the arrow 0;, Fig. 1, and to pass around the stem P of the puppet-valve into the standpipe, thereby allowing the water in the standpipe to vent itself through the bleeder-outlet Dand preventing siphoning the hose back through the bleeder.

, Having thus described my invention, What I'claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character described, the combination with the bleeder, of the fitting connected therewith and formed with juxtaposed valve-seats and an opening therethrough in alinement with said valve-seats, a tubular piston fitted in said opening and carrying a valve which is adapted to rest alternately on the seats, and a puppet-valve having a stem guided in the piston and arranged to close the opening in the piston, as set forth.

2. In a device of the character described, the combination with the bleeder and stand pipe, of the fitting connected therewith and formed with a lower valve-seat, an upper valve-seat, and an" opening therethrough above said upper seat, a tubular piston fitted in said opening and carrying a valve adapted to rest alternately on said seats,and a puppetvalve arranged to close the opening through said piston, as set forth.

3. In a device of the character described, the fitting formed with a Valve-seat and an opening thereabove, a tubular piston fitted in said opening and carrying avalve adapted to rest on said seat, a cage secured to said piston below said valve and formed with guides and a cross-bar, and a puppet-valve formed with a stem fittedto slide in the lower end of said piston with openings around it, said valve being adapted to close the opening through the piston and drop upon said cross-bar, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES P. BENTON.
