Description
UNITED S'rArEs JOSEPH ADAMS, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO HIMSELF AND WILLIAM STIOKNEY, OF SAME PLAGE.
IMPROVEMENT IN GAS-REGULATQRS.
Specification forming part of Letters Patent No. 150,502, dated May 5, 1874; application filed April 21, 1874.
To all whom it may concern:
Be it known that I, J osErE AnnMs, of Washington city, in the District of Columbia, have invented a new and Improved Gas-Rega lator; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this speciication, in whic Figure lis a vertical central section of gasre'gulator; Fig. 2, top view ot' same; Fig. 3, section of anges of balloon hemispheres. p
This invention relates to that classof gasregulators in which the pressure of the gas acts upon a flexible diaphragm, to which is attached a valve that opens or closes as the gas is turned onor off from the burner,or as the pressure varies from the street-mains, and it consists in a new and improved arrangement, in which the valve is made more sensitive to the pressure of the gas by means of a balloon-like arrangement of thin metal in the diaphragm that opens down through the valve, and, being constantly filled with gas, counteracts by its buoyancy the weight of the valve, and hence makes the diaphragm as connected with the valve more sensitive to the pressure of the gas.
In the drawing, A B represent two hollow cases of metal, having anges a b, which are fastened together by screws or bolts. In between these two flanges is fastened, with a gas-tigl'it joint, the outer edge of a flexible annular diaphragm, C, to be made of leather or other suitable material. The inner edge of said diaphragm is fastened by rivets between the anges o d of the thin metallic hemispheres D E, that form the balloon, one of the langes c d having a rim or ledge to insure a gas-tight joint. Upon the top of hemisphere D is a short rod or stem, F, upon which the weights a a fL'", of different sizes, are placed to adapt the governor to the variations of pressure for different elevations. ,y The heinisphere E opens, through a pipe, G, to the supply of gas from the meter below, said pipe Gr terminating in a funnel-shaped valve, II, that plays in the valve-seat I. This valve-seat is attachedto the bottom of case B, and is made of' non-corrosive metal, leather, or such other material as may be desirable. This valve-seat is also adjustable, and may be lowered to reduce the orifice b around the valve, and by this means adapt the governor to a low pressure of gas.` J is a chamber in which the valve plays, and connects case B with the outletpipe from the meter. K is a movable plate which is screwed into vthe opening in the top of the hemisphere A, and has in its center an aperture, o', fo'r the admission of atmospheric air to counteract the pressure of the gas upon the diaphragm. L is a conduit for the gas, and d the connection for thc service-pipe.
The operation of this governor is as follows: Adjust the valve H to the particular elevation or pressure of the locality by the weights a a a" upon the stem F, and now, as the valve, pipe, and diaphragm are in a state of suspension by reason of the buoyancy ofthe balloon, the pressure of the gas on one side being neutralized by the atmosphericair and weight on the other, the diaphragm is particularly sensitive to an increased or diminished pressure of gas.
If the pressure is increased, the diaphragm C, balloon D E, and valve- H are raised, and the oriice b proportionally closed, thereby checking the increased low of gas.
If the pressure is diminished, the diaphragm, balloon, and valve are depressed by the'airpressure and weights, the orifice b opened,
. and the low increased.
For very low pressures of gas the weights a a a may be taken entirely oft, and the valve-seat lowered, or both, as required.
By this delicate arrangement the flow of gas through the burners is made uniform an d inde pendent of the pressure from the main, and also of the number of burners employed at a time.
Having thus described my invention, what I claim as new isl. The balloon consisting of the thin metallic hemispheres D and E, with flanges c d, and the pipe G, opening through the funnel-shaped valve H, in combination with the diaphragm C, as and for the purpose specilied.
2. The adjustable valve seat I, in combination with the valve H, pipe G, balloon A B, and diaphragm- C, Vas and for the purpose speeied.
8. The stem F, With Weights a a am, in
combination with the balloon D E, diaphragm G, pipe G, and Valve H, as and for the purpose set forth.
