UNITED STATES PATENT OFFICE.
DAVID P. MAYHEW, OF DETROIT, MICHIGAN.
IMPROVEMENT IN GAS-REGULATORS.
Specification forming part of Letters Patent No. 163,937, dated June 1, 1875; application filed March 20, 1875.
To all whom it may concern Be it known that I, DAVID P. MAYHEW, of Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Gas-liegulator, of which the following is a specification My invention comprises a chamber receiving gas from the main, in which is an exitvalve, which is balanced by a water-valve, and is also connected by a lever and acouple of rods with another lever, having a counterpoise to be .set according to the pressure wanteth'and arranged in relation to another water-valve receiving the gas from the exitchamber, and acting upon the lever to close the exit-valve whenever there is an excess of pressure in the exit-chamber.
Figure l is a sectional elevation of inyimproved gasregulator, taken on the line o o of Fig. 4. Fig. 2 is a horizontal section taken on the line a; 00. Fig. 3 is a horizontal section taken on the line y y, and Fig. 4 is a horizontal section taken on the line 2 2.

A is the chamber receiving the gas from the main by the pipe 13, and containing the exit-valve U, which is connected, by lever D and rods E E, with the counterpoise-lever F. G- is the movable cap of a water-valve, through which rod E passes for a guide to said cap, the valve being open to the chamber'A to balance the pressure of the main on valve 0. I is the cap of another water-valve, through which rod E passes for a guide, and which is open to the exit-chamber, to be subject to the pressure therein. J is an adjustable weight on the lever F, to be set accordingto the pressure wanted in the exit-pipe K. It will be seen by examination of the drawings that whatever the pressure may be in the main the exit-valve will be so balanced that it will open by the excess of weight of cap I over that of cap G and counterpoise J acting through lever F and rod E, and that as soon as the pressure rises in the exit-chamber above the point for which the weight J is set the cap I will rise against lever F and close the valve until the pressure falls in the exit-chamber, so that said excess of weight of cap I over that of cap G and counterpoise J can move lever F and open the valve 0 again The caps G and I are controlled by the rods securely fixed to them, and working in the notches otzlevers D and F. A spring, L, is used when needed to check any tendency to longitudinal vibration.
The inlet and outlet pipes have a common diaphragm, to which they are joined, and openings N on all sides of the pipes, and on either side of the diaphragm M, into the chambers.
Having thus described myinvention, Iclaim as new and desire to secure by Letters Patent 1. In a gas-regulator, the combination of the water-valves G I, communicating, respectively, with the receiving and exit chambers A H, and connected with the exit-valve 0, substantially as herein described, for the purpose set forth.
2. The combination of the receiving-chamber A, exit-chamber H, exit-valve O, levers F D, rod E E, and water-valves G I, substantially as specified.
DAVID P. MAYHEW.
