UNITED STATES PATENT OFFICE.
GEORGE W. LAWTON, OF NEIV YORK, N. Y.
PRESSURE-REGULATOR.
SPECIFICATION forming part of Letters Patent No. 347,118, dated August 10, 1886.
Application filed March 9, 1886. Serial No. 194,567. No model.)
To aZZ whom it may concern:
Be it known that l, GEORGE W. LAWTON,
of the city, county, and State of New York, have invented a ntw and Improved Pressure- Regulator, of which the following is a full, clear, and exact description.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in bot-h the figures.
Figure l is a plan view of my new and improved pressure-regulator, and Fig. 2 is asectioual elevation of the same.
The invention will first be described in conncction with the drawings, and then pointed out in the claim.
A represents a main piston-cylinder, and B a valve-chamber connected therewith by the port a. The valvechamber B is connected by the pipe 0 to a reservoir, boiler, or conduit in which pressure of water, air, steam, or gas is maintained. Above the port a is formed in the valve-chamber B the outlet-port b to the open air.
In the main cylinder A is fitted the piston-' head D, to which is connected the piston-rod E, on which is placed the coiled spring F, which acts between the piston-head D and the capplate G of the cylinder A, The piston rod E is to be connected by a lever, H, or other suitable connection, to the let-off valve,
damper, or other pressure-reducing device, to
operate the same when the piston-head D is forced upward in the main cylinder A.
In the valve-chamber B is fitted the valve or piston I, provided with the valve-stem J, which passes through the stuffing-box K, and has the weights L attached to its lowerend, to hold the valve I at the bottom of the valvechamber, except when the pressure in the reservoir or conduit rises above the required point. When the pressure rises above the required point, the valve I will be lifted by the pressure of water, steam, air, or gas entering the pipe 0, and will pass the port a,whereupon the water, air, steam, or gas will enter the main cylinder A, and lift the piston D and piston -rod E against the pressure of the spring F. The movement of the rod E will open the let-off cock, or open the damper, or operate any pressure-reducing device to which it may be attached, by lever H,which will cause a reduction of pressure in the main reservoir or conduit, whereupon the valve I will be lowered by theweights L in the valve-chamber B to its original position, ready for operation again when the pressure shall rise above the required point. The piston I in its downward movement in passing the port a opens the escape'for the main cylinder A through the openings a b, so that the spring F will react and force the piston D and rod E downward to theiroriginal position.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The combination,with the main cylinder A and the valve-chamber B, having a connecting-port, a, and an exhaust-port, b, above port a, of the piston D in the cylinder A, the piston-rod E, means for forcing the piston downward, the weighted valve I in chamber B, and the pipe 0, entering the chamber 13 below the valve I, the valve inits normal position being below the port (1, whereby when the pressure in the chamber B ceases the valve will-fall, and the fluid in the cylinder A be forced out by the piston D through the ports a 1), sub stantial] y as set forth.
GEORGE W. LAIVTON.
