Description
UNITED STATES EEICE.
PATENT THOMAS RICHARDS, LANSINGBURG, NEW YORK.
Specification forming part of Letters Patent-No. 54,959, dated May 22, 1866 antedated May 7, i866.
Vof the cylinder by a conical valve in such a manner that the valve is at all times balanced, and by the oscillating motion of the plug the alternate transmission of steam may be effected.
To enable others skilled in the art to make and use my invention, I proceed to describe its construction and operation.
Figure-l represents a section of my valve, showing double ports, 011e on each opposite part of the valve, for the same purpose of transmitting steam to the cylinder and exhaustpassages. a a are the passages connecting with the boiler by a double steam pipe. b b are exhaust-passages for giving the steam into the smoke box 5 c, port for conducting steam and exhaust alternately to and from one end of the cylinder; d, for conducting steam to the other end and exhaust-port alternately by the oscillation of the plug. The valve being in its place, we will suppose the plug in the position shown, covering the two steam and two exhaust ports. Thus there will be no communication with either end of the cylinder. This is from one end of the cylinder to the other. Now, if the plug be moved the steam will bc admitted to one end of thc cylinder,'and that which is way round the valve in the casting or by a pas-4 sage across the opposite head.
Fig. 2 represents a perspective view of my valve suitable for a locomotive, with the steam and exhaust pipes for conducting the steam to and from the cylinder in the back end of the smoke-box.
Fig. 3 represents the plug with four cavities, two of which, c c, are seen with the opposite cavities in the plug, receive and transmit the steam to the cylinder and exhaust-passages.
I do not claim for the number of ports in the valve-seat and cavities in thevalve, that having been patented to myself February 23, 1858, (then residing in Plattsburg, New York.)
What I claim as my invention, and desire to secure by Letters Patent, is-
The Within-described arrangement of the ports in valve-seat and valve, so as to make the steam and exhaust ports balanced under any pressure of steam, substantially as set forth.
