GAS- REGULAT R.

SPECIFICATION forming part of Letters' Patent No. 245,579, dated .August 9, 1881.

Application filed March 31, 1881. (No model.) Patented in England May 6, 1880.

, SUGG, of Vincent Street, in the city ot' Westminster, England, have invented certain Im4 provements in Gas-Regulators, of which the following is a specification.

ln the gasregulators at present in use great `inconvenience has been experienced from the corrosion of the metals of which they are formed, such corrosion serving to tix the floating part of the regulator and stop its action; and to avoid this so loose a tit has been given to the lioating portion ot' the regulator that a large proportion of gas was enabled to escape past its periphery.

The object of the present invention is to provide a gas-regulator that will not allow the gas to pass through without regulation, its tloating part having no tendency to become xed in its cylinder through the corrosive action of the gas.

The .invention applies, chieiiy, to small regulators attached to burners; and it consists in iitting within a cylindrical chamber in the lower part of the burner afloating gas-holder, composed, by preference, of steatite, which holder will be free to rise and fall according to the varying pressure of the gas, and by its movements increase or diminish the supply of gas to the burner.

The invention. admits ot' various modifications, as will be presently explained.

In the accompanying drawings,'Figure ll shows in vertical section, on an enlarged scale, my improved gas-regulator fitted to a flat-llame burner. Below the burner a is a cylindrical chamber, b, in which is fitted, so as to form a lining thereto, an inverted cylindrical vessel of steatite, c, which has a central tubular extension, c', that is closed at top and has lateral passages c2 for admitting the gas into the neck b of the casing b.

Fig. 2 is an external view of the lining detached from its chamber or casin g. The cham.- ber bis closed at bottom by a threaded metallic piece, d, having a screwed neck which iits into the gas-supply pipe. Within the vessel c, I fit what may be termed a lioating gasholder, c, which is free to rise and fall in the inclosing-vessel without allowing gas to pass between it and the lining c. This gas-holder carries at its upper end a cylindrical tube, e',

which acts as a check-valve, and is drilled through the center to admit ot' adetinitequautity of gas passing up through it.

Fig. 3 shows the gas-holder e with its cylindrical valve e' as detached from the regulator. The tube e', acting as a valve, enters the tubular extension c of the lining c, and it is free to slide up and down therein as the pressure ot the gas varies. The lateral passages c2 in the tubular extension c allow of the gas which passes up through the valve e escaping into the neck b and so passing oft' by a central opening, b2, at the upper end of the casing to the burner a. When the normal pressure ot' the gas is exerted the gas will iiow upward iu the course indicated to the burner. The action, however, ot' any undue pressure will be to lift the gas-holder and with .it the valve c', which will then partially close the lateral passages c2, and thus diminish the supply. To prevent a too sudden rise ot the valve a lateral opening, e2, is made in it to supply gasto the space in the chamber b above the gas-holderc. The elasticity of thisimprisoned gas willetlf'ectually prevent the too sudden rise of the valve, which might otherwise have the effect ot' extinguishing the light.

I would remark that by enlarging the diameter of the regulator it may be used for controlling two or more burners; butit is not intended to take the place ot' those classes of gas-regulators which control the whole supply of a large establishment.

In some cases I propose to make the gasholder and valve of non-oxidizable metal, which will work smoothly and without risk ot' sticking within a steatite lining and valveseat; or I may use a non-oxidizable metallic lining and form the valve-seat ot' the same material, using therewith'a gas-holder and valve of steatite, as explained. The steatite will be shaped in the lathe when inits natural or comparatively soft state, and it will admit 'ot' being polished and used without further treatment; but in some cases I may ind it convenient to subject the steatite portions ot' my regulator to furnace heat, which will greatly increase their hardness and strength.

IOO

I am aware that it has been proposed to employ soapstone or steatite in the manufacture of valves and valve-seats of the character in which the Valve closes against the seat, the function of the material being to resist the Wearing action of hot gases, Snc.v My improvement, on the contrary, relates to sliding valves operated by a varying pressure of gas, and the function of the soapstone is to prevent the interference with the movement of the valve due to corrosion or oxidization.

I am also aware that a sliding valve having a lateral opening below the valve-seat has been used in a gas-regulator, but said lateral opening did not occupy such a relation to the valve-seat, casing, and float as to render it capable of performing the function ot' thelateral opening e'L in my valve.

Having now explained my invention, I wish it to be understood that I claim- 1. The combination, in a gas-regulator, of

the outer casing, a tubular valve-scat, c', arranged therein, and having a lateral openin g, c2, and a tubular valve, c', tted snugly to said seat, and adapted to be controlled by the pressure of gas, the valve or its seat being composed of steatite, whereby corrosion ot' the surfaces and interference with the sliding movement ofthe valve is prevented, as set forth.

2. lhc combination of the outer casing, the tubular valve-seat c, having a lateral passage, c2, and the tubular valve e', having beneath the valve-seat a lateral passage, e2, and float e, as set forth.
