"UNITED STATES PATENT OFFICE.
R. L. MILLS, OF LANCASTER, OHIO.
GAGE-COCK.
Specification of Letters Patent No. 22,189, dated November 30, 1858.
To all whom it may concern:
Be it known that I, R. L. Mines, of Lancaster, in the county of Fairfield and State of Ohio, have invented a new and useful Improvement in Gage- Cocks for Steam- Boilers, which may be also applied to other steam cocks; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings making partof this specification, said drawing being a longitudinal central section of a gage cock with my improvement.
This invention consists in a certain arrangement of two conical. valves on a screwed. stem in combination with a female screw and a certain arrangement of two conical within the cock, whereby all packing for the stem is dispensed with, and yet the escape of steam around the stem when the cock is open is effectually pre vented.
To enable others skilled in the art to make and use my invention, 1 will proceed to describe its construction and operation.
A, is the shell of the cock, made of brass or other metal with a globular chamber B, near the middle of its length, and having female screw threads a, and 2), out in its interior from said chamber to each end. The first mentioned screw thread a, which runs to the end which screws into the boiler be ing to receive an externally screwed lining tube C, of hardened steel in the front of which is a conical. valve seat 0. The other screw thread Z9, which runs to the outer end of the shell, is to receive a screw thread 6, cut on the exterior of the valve stem D, said screw thread 6, being the largest portion of the stem. At the inner extremity of the valve stem, which is of steel and hardened, there is a conical valve (Z, which is ground to lit the seat 0; and in front of the screw thread 6, the other conical valve f, is formed to fit to a seat 9, in the cap E, which screws tightly on the outer end of the shell A, and said valve is ground into said seat. The
part 71, of the stem in front of the valve f, is made cylindrical and smaller than the said valve and fits into the cap E, and the portion 2', of the stem in front of h, is squared to receive a wooden knob F, which serves as a handle to turn the stem. The
valves and seats may be relatively so arranged that about half a turn of the stem will draw the valve d, from its seats 0, and bring the valve f, to its own seat 9, and vice ocrsa. From the chamber B, a nozzle k, extends downward for the escape of steam or water.
This cock is opened by turning the handle to the left till the valve f, stops against the seat which is the condition represented in the drawing. This leaves a passage open from the boiler between the valve 0, and seat (Z, to the nozzle 7a, but any escape round the front of the valve stem is prevented by the valve f, which dispenses with packing of all kinds and is much more durable. The cock is closed by turning the handle back till the valve (Z, stops in its seat 0.
By the use of the hardenedsteel valve (Z, and seat 0, the cock is not likely to be injured very soon by the action of the steam or of any mineral impurities in the water which are so destructive to brass and composition metals.
It will be observed that both of the valve seat holders C and E are adjustable, so that the seats (0, g) may be set up, as fast as they wear and thus form tight joints, at all. times.
I am not limited in the application of my improvement to gage cocks. It may be employed in connection with steam whistles, oil cups, double valves, etc, with equal advantage, and also in all cases where valves without packing are wanted.
I do not claim, broadly the invention of double valved stems so arranged that when one valve is withdrawn from its seat, the other shall be drawn into its seat and thus stop the escape of steam, without packing, for I am aware that such devices are old; but
' lVhat I claim as my invention and desire to secure by Letters Patent, is
The arrangement and combination of the lining tube C and cap E, containing the ad justable seats (0, g), with the double valved stem D, as and for the purposes herein shown and described.
