Letters Patent No. 59,752, dated November 20, 1866.
S PECIFICATION. TO ALL WHOM IT MAY CONCERN Be it known that I,' GEORGE E. WHITMORE,O` Housatonic, in the county of Berkshire, and State of Mas- Y sachusetts, have invented a new and improved steam cock, and I do hereby declare the following to be a full and exact description thereof-reference being had to the accompanying drawings and to letters and figures marked thereon: v l The nature of my invention is an improved steam cock, which is cheap, durable, and effective, and removes some of the objectionsto steam cocks now in use.
Fig. 1 represents a half section of the steam cock cut lengthwise, in which the sliding valve A is shown in the barrel of the cock B B B B, showing the valve stem C C and the crank pin D, which, when turned in the slot E of' the valve A, forces the valve A up against and into the valve seat F F, thus closing the orifice through which the steam passes.
C C is the valve stem.
G G is the ground joint at inside end of valve stem C C.
H H is a lead ring or its equivalent at outside end of valve stem C C, which forms a durable and eicient packing for lvalve stem C C, to prevent leakage of steam.
l I I is a choke plug, which is cast on or otherwise secured to the valve A, which passes into the orifice through which the steam passes in valve seat F F, choking the steam back when but little is required, so that the cutting of steani when passing is on the choke plug I I, and not on the valve A or valve seat F F. Fig. 2 represents the inside end of valve stem C C and crank pin D, where it connects with valve A.
Fig. 3 is a side view of the sliding valve A, showing the slot E in which the crank pin D moves in opening and closing valve A.
Fig. 4 is an end view of the sliding valve A, showing the flanges which hold it in place in the barrel B B B B, and allow free passage of steam when open.
Fig. 5 represents the cock in its finished state.
What I claim'as my invention and desire to secure by Letters Patent, is
rlhe eccentric pin in combination with the valve stem for forcing the valve A against and into the valve seat F F. I also claim the choke plugI I, Whichprevents the valve A and valve seat F F from being worn by the action of the steam in passing between the valve A and valve seat F F. I also claim the arrangement of the ground joint G G at the inside end of Valve stem C C and lead ring H H or equivalent at outside end of n valve stem C C, which forms a doublepacking. Y And the combination of all these parts in the manner and for the purpose specified. GEO. E. WHITMORE.
