Description

UNITED STATES PATENT 'QEEIoE GEORGE F. BLAKE, OF BOSTON, MASSACHSETTS.
IMPROVEMENT IN VALVES FOR STEAMV-E-NGINES.
Specification forming part of Letters Patent No. 123,669, dated February 13, 1872; antedated January 29, 1872.
I, GEORGE F. BLAKE, of Boston, countyof Suiolk, Commonwealth of Massachusetts, have invented an Improved Valve for Steam-Engines, of which the following is a specication:
Nature and Object of Intention.
My invention relates to the form of valve known as the cylindrical slide-valve, and has for its object the prevention of leakage between the ports when the vvalve shall have become worn by use. The cylindrical slide-valve is usually formed of a number of pistons con- A nected by a cylindrical center piece of less diameter, the pistons being of the right Width of face and placed the proper distance apart 'to form-the valve.
My improvement consists in casting the longitudinal bridges a a across the space between the piston s and turning the said bridges -lush with periphery of the pistons. A sufficient number of these bridges are so arranged f between the pistons that in whatever position lcylindrical slide-valve, when constructed and operated substantially as and for the purpose mentioned.
The above specification signed and Witnessed at Washington this 10th day of June, A. D. 1871.
GEO. F. BLAKE.
