GAS-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 331,890, dated December 8, 1885.

Application sied october 9, isst. semi No. 119,399. (No man.)

To all whom it may concern:

Be it known that I, PETER KELLY, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Gas-Governors, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to gas regulators or governors of that class in which afloat attached to a valve-rod is employed, my object being to provide a cheap simple device for regulating the flow of gas from the meter to the housepipes and burners, one which shall consist of as few parts as possible, and which may be cleaned or repaired by a person unskilled in the construction of gas governors or regulators; and the invention consists in certain features of construction hereinafter described, and particularly pointed out in the claims.

Referring to the drawings, Figure l is a central vertical section of a gas-governor constructed in accordance with my invention. Fig. 2 is a detached view in side elevation of the four-way coupling and valvetube. Fig. 3 is a detail, in perspective, of the valve and its rod. Fig. 4 is a side elevation of my oat, parts being broken away, showing internal construction.

Like letters indicate like parts in all the igures.

A represent-s a four-way coupling, which, in order to reduce the number of parts, is preferably cast in asingle piece. The branch B is the valve-tube, the top of which is open, except that it is provided with a cross-bar, B', having a central aperture, B2, that serves as bearing for the valve-rod.

A represents the branch that receives the pipe leading from the meter, and A2 the pipe leading to the burners. The branch A extends within the casting A, terminating, short of the middle thereof, in a valve-seat, A3, adapted to slide, upon which is a gate-valve, C, said valve being secured to the lower end of a valve-rod, C', by screw-threads or otherwise, which rod passes up through the valvetube B and the apertures B2 of the cross-bar B'.

Mounted upon the top end of the valve-rod C', and secured in a desired position by two nuts, D', is a float, D, which is made of light sheet metal and formed in the shape of au inverted truncated cone. This float is formed with a dome-shaped top, D2, and from the truncated portion, and extending upwardly therein, is a cylindrical sleeve, D, adapted to loosely fit the valve-tube. For the purpose of retaining the valve C snugly against its seat A3, the branch A has formed thereon, at its inner end, a guiding-lug, At, th rough which said rod passes.

The tube B has formed at its junction with the body portion of the casting A a screwthreaded shoulder, B3, and screw -threaded thereon, and forming a jacket or covering for the float, valve, and rod, is a glycerine receptacle or reservoir, E, which conforms substantially in shape to the float D, it being provided with a closely-fitting dome-shaped cover, E, at the top of which is a vent or opening, E2. The vent E2 in the cover may be omitted, if desired; but when retained it permits a passage of air in order that the doat may be more sensitive to the variations of the supply of gas than it would be if cushioned against a confined body of air.

lt will be noticed that all the parts of my governor are exceedingly simple, and that they are readily attached to or detached from each other for the purpose of inspection and repair.

lt will also be noticed that the oat D is apertured, as at D", (see Fig. 4,) in order that it may receive within itself a body of glycerine, which acts to secure a balance or steady movement in its elevations and depressions, so that there is a more direct action thereby in the line of and upon the valve-rod, and thus friction between the moving parts is greatly reduced. j

In the course of time the governor may, by reason of grit, drip, and other matter coming in contact with the valve and its seat, fail to work satisfactorily. To remedy this a thorough cleaning is required. Now, by the peculiar and novel arrangement of' the parts, as hereinbefore and hereinafter described, it will be seen that this may be readily and easily accomplished.

'By removing the cover E' and the adj usting- ICO nuts D' upon the top of the valve-rod C', and unscrewing the plug F', it will be seen that the float may be withdrawn, cleaned, and replaced. So also may the interior of the reservoir or glycerine-receptacle be cleaned by Iremoving the top E'. The valve may be readily cleaned by removing the cover E' and nuts D' and unscrewing the plug F', which for that purpose is screw-threaded into the branch F of the casting A. Thus it will be seen that all the interior parts may be readily cleaned and replaced quickly and with little or no trouble. This removable plug F', in connection with the valve and rod, forms an important novel i'eature of my invention.

A sufficient quantity of glycerine having been poured into the receptacle E, as clearly shown in Fig. l by dotted lines, will, by reason of the apertures D, arranged around the bottom of the iioat D, pass within the iioat and within the sleeve D3, as before stated. rI`he gas now entering through the branch A' passes up through the valve-tube, out at the top through the openings thereof, and into the space bounded by the upper surface of the glycerine and the upper portion of the float, thence back down through said tube and out at the branch A2, so that a body of gas subject to fluctuation by reason of variation of pressure is contained within the iioat and extends to and is connected with the supply, so that variations in the supply are communicated to the gas in the `iioat and causes said iioat to rise and fall with the increase or decrease, respectively of said pressure. Now, should the pressure of gas become excessive, it raises the iloat in accordance therewith, which, by reason of its connection with the valve-rod, it in turn draws up the valve E, and thus diminishes the iiow or passage of gas to the burners.

For the purpose of preventing an entire cutting off of the supply, I have provided the 'valve `G with a small opening, C2, so that should the supply be so great as to draw the valve up and completely cover the supply-V pipe a sufficient quantity of gas will still be allowed to escape through said opening to the= burners to keep them lighted or to provide sufficient gas to keep the pipes full, readyfor lighting at the burners. Now, on the other' hand, should the supply become light, the

` valve, in contradistinction to the above described operation, will fall, and for the vpurpose of allowing an unobstructed passage for the gas-that is to say, to allowT the valve to fall until the opening is completely unobstructed-I have formed a recess, F, in the plug F' for the reception of the lower end of 'said valve.

It will be readily seen that minor changes in lconstruction may be made-for instance, the valve may be upon the Oppositepipe of z the coupling, or the gas may be introduced at either side of thevalve. It is also apparent that the entrance or induction pipe A' may be Vformed separately and screw-threaded into the coupling A, as may also be thevalve-tube B.
