Some of these devices any suitable manner with the movable part have many things in common with my imof the variable chamber,.such movable part proved regulator.

Figure 1 of. the drawings represents au exterior vside elevation; Fig. 2, a vertical cut section ;Fig. 3 a plan view, with both rigid and ilexible covers removed. Y Lettery A' represents a .variable chamber inclosed at the sides and bottom 'by the rigid vwalls A, and at top-by theA flexible cover c,

which may be made of india-rubber or any suitable material, and confined to the rigid sides by the rigid cover B and washer d, as

l shown, or in any other suitable manner. Letv ter U' is the eduction-pipe. (Shown cut o, but

to be connected in any suitable manner with the gas-burners.) Letter C represents the induction-pipe. (Shown cutoff, but to be connected iu any-suitable manner with the gasholder or source of supply.) The inductionpipe C connects with the variable chamber through the stop-cock F, letter e' being the gasway, and F' the handle of the stop-cock.

The variable or movable part c of the variable chamber is acted on, anta gonistcally to the pressure of the gas admitted within the chamber, by the spring a, which is connected.

with the movable part by the rod b, and also with tlLe stationary or rigid part of the chamber by the adjustable screw-plug a',.which is approachable from the exterior for the purposeof regulating the tension of the spring through the screwhole D D, the orifice of which .is closed gas-tight by the screw-.stopper E'v andavrubber packing-ring e. The handle of the stop-cock is connected to therod b.

. The action of the spring is to diminish the size of the variable chamber, and at the same time fopen the stop-cock. The force of the gas acts to extend the variable chamber and close the stopcock. 1 Therefore the tension of the spring must be ance such a degree of pressure of the gas admitted within the variable chamber as is necessary tokeepup a proper average supply of gas tothe burners, and the cock must be so adjusted in connection with the movable part of the variable chamber controlled by the spring, that by its action the cock will vbe kept open or partially open so long as the pressure of the gas within the chamber does not exceed the force of the spring, varying the opening in proportion to the degree of excess of pressure of the admitted gas over and above the force of the spring. The precise manner in which a spring or its equivalent may be made to actuate the moving part of the variable chamber in antagonism to the pressure of the admitted gas is not a matter of importance so long as it i's .eectual and such movable part of a variable chamber is connected with-astop-cock through which the gas must pass on its way from the gas-holder or source of supply to the variable chamber.

I claim as my invention'and improvement- In gas-regulators a` stop-cock situated in, and controlling the passage-way from the gasholder or other sourceof supply to the variable chamber, in combination with the moving part of the variable chamber, substantially as described. f,
