IMPROVEMENT IN ,STEAM GAGE-COG KS.
Specification forming part of LeiifeixPatent No. 52,452, dated February 6, 1866.
To all whom it may concern:
Be it known that I, JOHN G. SCHAEFER, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented an Improved Self-Packing Steam-Valve andGage- (Jock; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.
The nature of myinvent-ion consists in using in a gage-cock a self-packing valve or plug as a substitute for the ordinary packing now used for making it steam-tight, and combining it with the try-cock in such manner as is hereinafter shown.
' To enable skilled mechanics to make and use my invention, 1 will proceedto describe its construction andoperation.
The accompanyingdrawing is a longitudinal section.
A is a gage-cock, formed in two parts,B B, which are joined at b, the 'part B screwing into and communicating with the boiler. .The cap or part B contains the conical or packing valve 0, the stem 0 of which passes steamtight through the neck d. Itis furnished with a'screw, c, and nut. f, between which nut and the top of the cap thelever h or other suitable mechanical agent for giving rotary motion intervenes. When the nut is screwed down on the lever the valve is held tight in its seat It and the gage-cock made steam-tight, thus obviat-in g the use of the ordinary packing, which is so liable to be burned or destroyed by the heat from the steam.
square shank, l, is attached to the valve 0, eithencast to it or otherwise. The cap below the valve-seat k is enlarged and has a screw, m, cut in, the opening, into which the screw-stem a of the try-valve D is screwed. The shank Zfits into a correspondingjsocket, o, in the stem *n. I
It will be seen that when a rotating motion is given to the shank l by the lever the'screwstem 71. is also caused by the shank to rotate and is screwed either up or down, and-the trycock or valve D is opened or closed according to the direction given to the lever.
My gage-cock can be used for a steam stopvalve by arranging the channel 1" and the vent s for pipe-connections, the try-cock D being attached to the cap.
The valve-seat t can-be very readily repaired without detachin g the part B from the boiler.
I do not confine myself to a square shank and socket, but will construct them of an y convenient number of sides.
What I claim as my invention, and desire to secure by Letters Patent, is,
The packing-valve U, the shank l, and the socket o in the stem a, substantially as herein specified and described.
In testimony whereof I. hereunto sign my name to this specification in presence-of two subscribing witnesses.
JOHN G, SOHAEFER.
