GAS BEDUCING REGULATDR.A
(Application led Apr. 4,1898.)

EDWARD E. MURPHY, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO JOHN JOYCE, OF ANDOVER, MASSACHUSETTS.
GAS-REDUCING REGULATOR.
SPECIFICATION forming part of Letters Patent No. 619,206, dated February 7, 1899.y
Application filed April 4, 1898. Serial No. 676,275. (No model.)
To all whom it may concern,.-
Be it known that I, EDWARD E. MURPHY, of Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Gas-Reducing Regulators, of which the following is a specification.
My invention relates to vimprovements in gas-reducing regulators; and the object is to regulate the supply and reduce the pressure of gas between either the generator or source of supply and the pipes leading to the burners. By accomplishing this result there is no blowing of the gas at the burners and a steady light is maintained reduced by the regulator from any pressure.
My invention consists of certain novel features hereinafter described, and particularly pointed out in the claims.
In the accompanying drawings, which illustrate a construction embodying my invention, Figure l is a plan view of my improved gas-reducing regulator, partly in section, to show part of the interior construction. Fig. 2 is a central longitudinal section through the gasireducing regulator. Fig. 3 is a modification hereinafter described. Fig. 4c is a detail View showing the serrated valve. Y
Like letters of reference refer to like parts throughout the several views.
A represents a suitable casing having an inlet gas-conductor B and an outlet gas-conductor C. The source of supply enters from the generator through the conductor B and passes to the pipes, which lead to the burn ers from the conductor C.
D represents arestricted valve-seat located within the conductor B and provided with a suitable opening D', through which the gas passes as it enters through the conductor B into the casing A. Within the conductor B at the inner end is located the piston-valve E, having on its outer end a soft flexible seat E', which closes the opening D' when in the position shown in Fig. 2, as would be the case when piped up, because the pressure on the service-pipes acts on the diaphragm in the casing A and shuts the valve E. This valve E is provided with serrations E2, (shown in dotted lines, Fig. 2, and in full lines, Fig. 4,)
through which the gas passes When the valve is open upon a reduction of pressure.
The valve E is provided at F With a bellcrank lever F', which is pivoted to the casing A at F2 and at F3 is pivotally connected to the rod G, which extends upwardly through the yoke I into the spring-casing H2, Where said rod is provided with a disk H', against which bears one end of the coiled spring H3, and the other end of said spring bears against the disk J of the regulating-screw J', provided with the operating-handle J 2.
The yoke I is secured by screws I' to the outer edge of the casing A, and between said yoke and the casing A is a diaphragm K, of rubber, which within the casing A is provided with an upper and a lower metal disk K' to stiften it and to provide an area for the gaspressure to act upon to operate the valve E as the pressure varies. In other words, the disk K' provides a rigid surface against which the pressure acts. The rubber diaphragm K acts as a iiexible disk and also as a packing where the yoke I is joined to the casing A, and by reason of this diaphragm being of rubber a flexible movement is provided therefor.
L and L' represent upper and lower washers secured around the rod G at the center of the diaphragm to hold the two disks K' and rubber K in their proper positions.
With the valve E in the position shown in Fig. 2 it will be assumed that the gas is now being lighted at the burners, in which condition the pressure on the diaphragm K is reduced and the spring H3 forces down said diaphragm, thereby reducing the pressure and opening the valve E, which remains open until the pressure has increased sufficiently' within the service-pipe to close said valve E by acting on the diaphragm against the spring H3. In case there is not sufficient pressure on the burners to give a full flame the pres'- sure of the gas may be increased by turning the regulating-screw J so as to increase the tension of the spring H3 and diaphragm K, whereby more pressure is required on the diaphragm to close the valve.
The bell-crank lever F is provided for the purpose of operating thel valve E at slight variations of pressure on the diaphragm, which in turn allows a supply of gas in proportion to the amount which is required to sustain the pressure on the burners. Therefore by providing a lever of this construction there is provided suieient movement at slight variations of pressure on the diaphragm and leverage to operate the valve.
Instead of the regulating screw J and spring H3 the disk H may be shaped into a cup H4 for holding Weights H5, (see Fig. 3,) or any other form of Weight may be employed for varying the pressure of the diaphragm on the gas.
I do not limit myself to the arrangement and construction shown, as the same may be varied Without departing from the spirit of my invention.
Having thus ascertained the nature of my invention and set forth a construction embodying the same, what I claim as new, and desire to secure by Letters Patent of the United States, isv l. In an apparatus of the character specified, a casing, inlet and outlet conductors connected with said casing, a valve-seat having an opening therein located in said inlet-conductor, a valve movably mounted in said in let-conductor and having passages leading through the same and adapted to register with said valve-seat to control the opening in the said seat, abell-crank pivoted in said casing and having one of its arms pivoted to said valve, a flexible diaphragm mounted in said casing and adapted to be operated by the pressure of the gas contained within said casing, a rod connected withvsaid diaphragm and pivoted to the free arm of said bell-crank, plates mounted on opposite sides of said diaphragm, washers clamping said plates and diaphragm together and securing the same to said rod, and means acting on said rod for varying the pressure of the diaphragm on the gas.
2. In an apparatus of the character specied, a casing, inlet and outlet conductors connected with said casing, a valve-seat having an opening therein located in said inlet-conductor, a valve movably mounted in said inlet-conductor and having passages leading through the same and adapted to register with said valve-seat to control the opening in the said seat, a bell-crank pivoted in said casing and having one of its arms pivoted to said valve, a flexible diaphragm mounted in said casing and adapted to be operated by the pressure of the gas contained Within said casing, a rod connected with said diaphragm and pivoted to the free arm of said bell-crank, plates mounted on opposite sides of said diaphragm, washers clamping said plates and diaphragm together and securing the same to said rod, a disk carried by said rod, a reguA lating-screw, and a spring interposed between said screviT and said disk.
In testimony whereof I have signed my 65
