PRESSURE REGULATOR.
No. 889,065. Patented Sept. 4, 1888.
UNITED STATES OONltAlD EUBICH, OF PITTSBURG,
ASSIGNOR OF ONE-HALF TO JOHN EURIGH, OF ALLEGHENY COUNTY, PENNSYLVANTA.
PRESSURE-REGULATOR.
SPECIFICATION forming part of Letters Patent No. 389,065, dated September a, 1888.
(No model.)
To all whom it may concern:
Be t known that I, Conniun Eomon, acitinon of the United States, residing at Pittsburg, 1n the county of Allegheny and State of Pennsylvania, have invented certain new and usef ul Improvements in Pressure-Regulators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawlugs, which form a part of this specification.
My invention relates to an improvement in pressure-regulators, the object being to close the valve against the diaphragm, and thereby avoid any quick movement of the same and prevent knocking This I accomplish by certain details of construction and combinanon of parts, as will be fully set forth hereinafter.
In the accompanying drawings, Figure l is asectioual elevation of my improved pressureregulator constructed in accordance with my invention. Fig. 2 is a sectional plan view of the same, taken on the line x :0.
To put my invention into practice, I provide a cylindrical box, a, divided by partitions into a number of compartments, the largest of which, I), is covered with a cap, 0, and securely attached to the box a. by a number of bolts (2. Through the center of this box a is a vertical valve-rod, 6, having rigidly attached thereto two valves, f, each having a seat formed in the partitions g, which divide the lower portion of the box a into three compartments, h t. These two valves f are made of different sizes, so that the area or surface of the valves against which the gas presses is different, the lower valve being smaller than the upper to permit the gas under high pressure to elevate the valves and rod. Attached to two of these chambers h i is the inlet-pipe k and outlet Z, the first-mentioned pipe, 5, carrying a high pressure of gas or other substance, and the other, by means of the working of the valve f, a low or moderate pressure.
Between the top chamber, 1), and that, h, beneath IS a valve-seat formed in the dividingwall at between the two chambers b h, in which seat a loose valve, 01, is made to operate. Theloose sliding valve a is normally elevated 01? 1ts seat when the valves f f are closed by means of a system of levers, p 1), connected to said valve and the vertically-movable valverod 6. The upper lever, 1), is fulcrumed at an intermediate point of its length to an upright arn1 ,w, of a fixture, 10, secured to the dividingwall or of the upper large chamber, b, in which chamber the system of lovers is located, and one end of said lever has a slotted connection with the valve-rod e, as at 19", while the other end thereof is connected to the lower lever, 19, by an intermediate link, 12 This lower lever is fulcrumed at one end to the fixture w, and has a slotted connection at an intermediate point of its length with sliding valve or, as at p. (Clearlyshownin Fig.1.) Theslidingvalvc it moves in a reverse direction to the valves f and rod 2, being seated when the latter are elevated by the system of levers depressing the same, and this movement of the levers and valve is assisted by means of coiled springso. Through the valve n is formed a transverse opening, Q, to allow the gas to escape slowly from the larger chamber, 1), to the next largest chamber, 71, beneath the same, with which chamber h communicates the low-pressure pipe Z.
Between the top flange of the upper chamher, I), and the cap 0 is a flexible diaphragm, r, secured rigidly at its center to the valve-stem e by means of suitably-constructed washers 8. Several weights, it, placed on the top of the valve-stem aserve as a means for regulating the opening and closing of the valve f.
In operation the gas under high pressure elevates the different-sized valvcsf and rod 6 a sufficient distance oil the seats to permit the gas to enter the chambers h and b, the valve n being opened and the levers p p and valve being unaffected by this initial movement of the valves f and rod e by reason of the slotted connections between the rod 6, valve or, and levers p12. The gas entering the chamber In acts against the diaphragm therein to wholly elevate the valve-rod e and valves f, and on the further upward movement of the Valverod the lovers p p are depressed to force the valve to its seat, and thus cause the gas to es cape from the chamber I) through the ports q into the chamber h and low-pressure pipe, thus obviating the quick or rapid return of the valves f to their seats.
Having thus described my invention, what I the stem e, the springs 0, one or more openings, q, through the said valve 72, and connec- 5 tions between the valve-rod e and the valve n for operating the same, substantially as described.
In testimony that I claim the foregoing I hereunto afifix my signature this 6th day of 20 January, A. D. 1888.
