To all whom it may concern:

Be it known that I, DELOs I-I. BUMPUS,a citi-l zen of the United States, residing at Centerview, in the county of Monroe and State of Ohio, have invented certain new and useful lmprovemen ts in Gas-Governors; and I do declare the following to be a full, clear, and ex; act description'of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and

to the letters of reference marked thereon, which form a part of this specification.-

This invention has "relation to improvements in gas regulators or governors; and it consists in the novel construction, combination, and arrangement of parts of which it is composed, all'as will be hereinafter fully explained, and particularly pointed out in the appended claims.

The annexed drawings, to which reference is made, fully illustrate my invention, in which Figure 1 represents a side view of my improved gas-regulator. Fig. 2 is a Vertical sectional view of the same Fig. 3 is a detail view of the tripping mechanism. Fig. 4 is a side View of a furnace, showing my device applied thereto.

Referring by letter to the accompanying drawings, A is a valve coupling, to the lower portion of which is cast an annular enlarged flange a, which is internally screw-threaded. toreceive the male screw-threads b on the drum 0, which in turn is female screw-threaded, as at d, between which and the male screw-threads e of a ringf secures in position a diaphragm g, which at the upper portion of the drum engages the lower end of a valve h, the stem 1. of which passes upward and th rough a stuffing-boxj at the top of the valve A and is provided with a coiled pressure-spring 70, whereby the lower end of the valve or piston is kept in contact with the diaphragm g, and connected to the bottom of this drum is a steam-pipe Z, which communicates with the interior of said drum, the passage e in the coupling remaining open to permit the gas to pass from the inlet-pipe-m to the outlet-pipe 'n to the fire-box of a furnace, where the gas is used as fuel. To the top of the coupling is arranged a horizontal bar 0, having a central opening and an arm p, bent upwardly,.

and to the end 1' of this bar is attached one end ofa link 8, while the upper end thereof is pivoted to a dog or trigger if, having a pointed end u, that engages a notch in the horizontal portion 12 of a bent arm on the end of the long weight-beam w. This beam is supported upon the valve-stem t', the upper end of which isseated in a depression w in the beam, and secured to the upper face of this beam is a fiat spring y, the free end a of V and out the other side thronghthe outletpipe to the furnace. The amount of gas being fed to the furnace is increased or decreased, according to the pressure of steam from the boiler entering the pipe Z, where it acts upon the diaphragm, which latter raises and lowers the piston, thus regulating the opening'in the coupling for more or less gas to pass through. In shutting OK the supply of gas entirely when the water is low in the boiler and there is danger the trigger of the beam is released and the weight and beam allowed to fall to the ground, thus closing the valve in the coupling. Connected to the steam-pipe is another steam-pipe c, to which is connected one end of a wire d, and the opposite end of this wire is tied to the free end of the flat spring, and when the water is low in the boiler the intense pressure of the steam will expand the pipe oand by so doing it causes the wire to draw the free end of.

said spring upward, thus releasing the trigger from the hooked end thereof and the notch in the end ofthe beam thereby per- IOCI mitting the link, beam, and weight to fall to the floor or ground. At the same time the piston is relieved from pressure and is caused to rise and close the gas-passage in the coupling by the pressure of steam upon the diaphragm, thus shutting off the supply of gas from the furnace.

It will be readily observed from the above description, when taken in connection with the accompanying drawings, that by my construction of such a device the gas is automatically fed and the flow is regulated, and when there is danger where the supply of water is low the supply of gas is shut off entirely, and a device, as herein described, is simple in operation and atthe sametime cheap to manufacture.

\Vhat I claim is- 1. In a gas-governor the combination with the drum having the diaphragm and steaminlet pipe of the coupling provided with the flange and piston or shut-off valve; the horizontal arm arranged upon the top of the coupling, the link engaging the end 1 of the arm 0 by its lower end and the trigger interposed between the spring and notched arm and the spring engaging the top of the link and trigger, and beam having the notch at one end and weight at the opposite end and a wire attached to the free end of said spring for drawing the spring, whereby the trigger and link are released, all substantially as described.

2. The within-described gas-governor comprising coupling provided with the piston or shut-off valve and stuffing-box for the stem thereof the female screw-threaded annular flange forming a part thereof, the drum provided with the male and female screw-threads, the ring having the male threads, the diaphragm secured in position between said ring and drum, the steam-pipe connected to the drum, the beam supported upon the upper end of the valve-stem carrying the weight, the horizontal arm secured to the top of the coupling and the releasing device composed of the link, trigger, pivoted thereto and flat spring, one end secured to the beam and the opposite free end engaging the upper end of the trigger and link, said beam provided with the notch engaged by the lower end of the trigger, and the wire for raising the free end of the spring whereby the link, trigger and beam are released, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

DELOS I-I. BUMPUS.
