CHARLES w. I-IENSON, or CHICAGO, I nvoIs.

GAS-REGULATOR.

Application filed November 20, 1911.

To all whom, it may concern:

Be it known that 1 CHARLES W. Hmvsoiv, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois,'haveinvented certain new and useful Improvements 1n Gas-Regulators; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

This invention relates to improvements 1n pressure equalizing valves, and more particularly to a regulating valve adapted for attachment to any supply pipe for deliveringa gasat a uniformpressure to the. device tobe supplied. This device is of that class set forth in my prior patents for gas regulator, No. 794,980, issued July 18, 1905, and pressure equalizing valves, No. 867,370, issued Oct. 1, 1907.

It is an object of this invention to provide an equalizing valve extremely sensitive in operationand which is susceptible to the slightest change in pressure in the main and in which delicate adjusting mechanisms are entirely eliminated.

It is an important object of this invention to provide a device ofthe class specified in which both the valve closure and seat may be removed'in order that either may be renewed should it be found necessary, or either may be reground to form a perfect seating.

It is also an object of this invention to provide a device of the class described in.

which the valve closure is rigid and the valve seat is movable to thereby entlrely eliminate the reactive pressure against the movement of the member for cont-rolling the admission of the gas.

It is a further object of this nvention to provide a device of the class specified of few parts, in which adjusting springs and other delicate parts are eliminated and which is positive inoperation.

The invention consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

Serial No. 661,214.

As shown in the drawings: 1, indicates a casing provided with an extension 2, of less diameter, which is removable, adapting eX- tensions with different sizes and lengthsof channels being secured thereto dependent upon the pressure of gas in the main. A cover3, is'threaded upon said casing to close the upper end thereof. An inlet at, opens into the extension and an outlet 5, opens from the casing. A channel or cup 6, is provided in the casing anda channel or cup 7, is provided in the extension 2, each of which is adapted to contain a sealing fluid such as mercury. Seated on the top of the inner wall 8, of the cup 6, is a guide plate 9, having a central aperture 10, surrounded by an upwardly directed flange '11. A movable cup 12, is inverted in the top of the casing with its flange extended into the channel 6, a sufiicient distance to provide a seal therefor and a sleeve or cylinder 13, extends into the lower channel 7, having the lower end sealed. 'Rigidly secured to the upper end of the cylinder 13, is a valve seat 141, having apertured lugs 15, integral therewith to which is secured a centrally apertured spider 16, by means of screws 17 A band 18, is secured to the inner side of the upper end of the cylinder 13, to reinforce the connection between the cylinder 13, and the valve seat 1 1, and to guidethe movement of the sleeve in the channel. integrally connected to said extension 2, is a boss 19, by means of ribs 20, in which is Secured a stem '21, the upper end of which is threaded in the valve closure 22, which is provided with a seating face on its under side, and, as shown, adjusting nuts 31 and 32, are threaded on said stem above and below the apertured boss 19, to permit the adjustment of the closure 22, at various positions. Integral with the valve closure 22, are downwardly directed radial lugs or guides 23, which engage within the seat 14, and guide the same in its movement toward and from the closure. As shown, a flanged collar 24, fits loosely within the aperture .10, and upon the flange 11, of the guide plate 9. A threaded guide stem 25, is rigidly connected to the spider 16, and extends upwardly through the collar 21, and the inverted cup 12. Threaded on said stem 25, is a sleeve 26, which bears against the under side of the cup 12, and isadapted to slide in thecollar 24:, as the pressure in the valve varies from time to time. Threaded on the upper end of the stem 25, is a nut 27, adapted to lock the cup in adjusted position.

The operation is as follows: The gas is admitted through the inlet 4, and passes between the seat and closure to the outlet 5, and owing to the construction of the valve the gas enters the chamber between the plate 9, and the cup 12, and exerts pressure on the under side of the cup 12, to hold the cup at the proper height. If pressure in the system is suddenly increased the pressure on the cup is correspondingly increased, raising the same and valve seat 14, to engage the closure 22. IVhen the pressure in the casing becomes normal, the cup drops slowly and by cushioning the gas therein prevents violent vibration of the cup and parts movable therewith, unseating the seat from the closure. Should the pressure in the main be diminished, the pressure on the cup being correspondingly diminished allows the same to lower, which lowers the valve seat admitting a greater volume of gas into the outlet, maintaining a uniform pressure and supply in the outlet pipe. Of course, when the pressure is again normal, the seat is adjusted to correspondingly decrease the gas admitted. Thus, for any fluctuation of pressure in the main, the valve delivers gas under a uniform pressure to the device to be supplied. Owing to the fact that the seat moves, back pressure is entirely eliminated, thereby providing a valve which is highly sensitive without employing sensitive adjusting parts. The seat may be adjusted to vary the distance from the closure by the adjustment of the sleeve Q-I and nut 27, by means of the stem 21, whichever is preferred. Accurate seating of the seat is insured by the guides 23.

Many details of construction may be changed and I therefore do not desire to limit this patent otherwise than necessitated by the prior art.
