CYLINDER-COCK.
SPECIFICATION formingpart of Letters Patent N 0. 737,383, dated August 25, 1903.
Application filed March 30, 1903. Serial No. 150,167- (No model.)
1'0 all whom it may concern.-
Be it known that I, JOHN MARTIN GALEY, a citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Cylinder-Cocks; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form a part of this specification.
My invention relates to improvements in cocks for use on steam-engine cylinders for the discharge of condensed steam, more especially that kind in which a pressure of steam or air is employed to close the cock, its opening being effected by means of a spring.
The object of the invention is provide a simple and efficient device of this kind which will not open accidentally, but remain positively closed until its opening is desired.
With this object in view the invention consists in anovel combination and arrangement of parts hereinafter described, and pointed out in the claim.
In the accompanying drawings, Figure l is an elevation of my invention. Fig. 2 is a vertical section thereof as applied to the cylinder of a steam-engine.
'Referring specifically to the drawings, 4: indicates a. casing having a threaded stem 4, by which it is screwed into the cylinder 0. The casing is squared at one end, as at 4:", to afiord a hold for a wrench to turn it. The numeral 5 indicates a cylindrical bore in the casing, in which a piston 6 operates, said piston having a valve-stem 7. The bore has a reduced portion 8, forming an outlet or discharge-opening which communicates with a passage 9 in the stem 4 to the cylinder 0. The condensed steam passes from the cylinder down the passage 9 and out through the outlet 8 when the cock is open.
Steam or air to operate the piston enters the casing behind the piston through a supply-pipe 4, which may be connected to the air-pump or boiler. When the pressure is turned on, the piston will carry the valve 7 to its seat 8 in the outlet 8 and close it. When it is desired to open the cook, the pressure is released and the coiled spring 10 forces the piston back. This establishes communication between the passage Qand outlet 8 and permits the condensed steam to freely flow from the cylinder. The spring 10 is coiled around the valvestem and is confined between the piston and a shoulder 5? in the bore 5, formed by the reduced portion 8 thereof. The piston and valve-stem both have a suit-able packing. In the casing on the opposite side of the piston from the pressure-inlet I provide a port 11, so that any fluid which might leak past the packings may be discharged therethrough. This is very important and prevents the formation of a pressure under the piston which might open the valve or bar its closing. The bore 5 is closed by a screw-plug 12. The piston head and screw plug have projecting stems 6 and 12, respectively, which abut to form a steam-space on top of the piston.
Having thus described myinvention, what is claimed as new, and desired to be secured by Letters Patent, is
A cylinder-cock comprising a casing having a port from the cylinder to the outside, a cylindrical bore, a reduced passage connecting the bore and the port, a piston in the bore, a valve for the port having a stem extending at a steam-tight fit through the passage to connect with the piston, an inlet to the bore on one side of the piston, and a spring in the bore on the other side thereof, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
. JOHN MARTIN GALEY.
