SPECIFICATION forming part of Letters Patent No. 662,938, dated December 4, 1900.

Application filed February I3, 1900. .Serial No. 5,065. (No model.)

Figure l is'a sectional elevation of a regulator constructed according to this invention and having a balanced valve. Figs. 2 and 8 are si mi lar views of modifications of the valve.

Referring to Fig. l, Ais the body of a regulator, and B the cover, having between them the diaphragm C, to which is fastened the cup D by means of the screw K.

E is a rod passing through plug I and havinga spring G pressing on its upper end, which is enlarged for that purpose.

H is a screw by which the pressure of the spring G on rod E can be adj listed. end of rod E is in contact with the upper end of screw K and exerts a pressure on it, and consequently on the diaphragm C, depending on the stiffness of spring G and the position of screw H. The part F, having the spring G, adjusting-screw H, and rod E, can be removed and the pressure on diaphragm C regulated by weights placed in the cup D.

J is an opening in the regulator-cover for the purpose of keeping atmospheric pressure on the top of the diaphragm C.V

Fastened at one end to screwK and at the other end to the lever N is a lever L, fulcrumed near the top of the standard M.

The lever N is provided with rollers at each end to allow for freedom of movement.

One end of lever N is kept in place by the projection O, and the opposite end operates lthe Valve T U by raising and lowering.

Valve T U is made up of two parts, each part having a seat. The upper part T is composed of wings or guides and having a screw t formed at its top in the center, which screws into a flat disk X, having an eye or loop projecting up for movably engaging one end of Thelower `lever N. Between the two parts of T is held a soft substance l, like rubber, for a packing to make a perfect joint at the valve-seat. The lower part U is fastened to T by means of a screw 4 and holds a packing 2, similar to l. U is recessed on its under side to take the packing 2, which is held in place by washer 3 and screw 4. The gas `entering at S presses equally up and down on valve 'l U, making it balanced and-easy to Operate with high pressures. When the valve T U is raised, part of the gas goes directly up into the regulator past valve T, and part goes down past valve U and through passage R to the regulator.

The outlet for the gas from the regulator is through the opening P.

It will appear from Fig. 1 and the foregoing description that when a pressure is exerted on the top of diaphragm C by means of the spring G or weights in cup D the valve T U will be opened through the operation of levers N and L. When sufficient gas has entered the regulator to raise the diaphragm C against the pressure above it, the valve T U is forced down and the supply cut olf. Upon the gas being drawn from the regulator through the opening P the diaphragm again falls and the valve T U is raised, repeating the cycle of operations.

Fig. 3 shows a modification of valve for high pressure to be used in place of T U when a balanced valve is not desirable. The opening for the gas is small and the seat is at the bottom. The end of the lever simply rests on top of the valve, and when it is raised it does not raise the valve, as in Figs. l and 2, but the valveA is vraised by the gas pressure below it.

Fig. 2 shows another modification of a valve for medium and light pressure and also a modification of guiding and seating the same.

Where valves shown in Figs. l and 2 are used, the gas can only enter the regulator through them, as no passage R is used.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

of gas, a weight supported upon the dia- Y.

phragm, a lever connected with the valve and having its opposite end fulorumed, said lever having a roller bearing at each end, and a second lever connected with the diaphragm and having its opposite end connected with the iirst-named lever at a point between the opposite ends of the latter whereby the valve is opened by the depression of the diaphragm and is closed by gas-pressure upon said diaphragm.

2. In a gas-regulator, the combination of a gas-chamber, a controlling-valve and a dial phragm, of a lever having one end connected with the valve and the opposite end fulorumed, rollers journaled in the ends of said lever, a standard or support, and a second lever connected at one end with the diaphragm, and fulerumed to said standard or support, and having its opposite end pivotally connected with the first-named lever at a point between the ends of the latter, whereby the sinking of the diaphragm raises the valve to admit gas and the ascent of ,the diaphragm, by gas-pressure, closes said valve and cuts off the gas-supply.

3. In a gas-regulator, the body or case hav ing a gas inlet and outlet, a valve having a loop or eye, and a weighted diaphragm, in combination with means for operating the valve consisting of a pairof connected levers one of which has its free end connected with the diaphragm and the other has its free end loosely and movably connected with the eye or loop of the valve and said rst-namedvlever fulcrumed between its ends whereby the weighted diaphragm opens the Valve and, gaspressure closes it.

4 The combination with a gas-chamber, a diaphragm and a gas-controlling valve having a stem provided with an eye orloop, of a lever having a rolling connection with said eye or loop and having a rolling fulerum at the opposite end, and a second lever fulcrumed between its ends, having one end conneoted with the diaphragm and the opposite end connected with the rst-named lever at a point between theopposite ends ofthe latter.

5. The combination with a gas-chamber having an inlet and outlet and a valve-controlled passage from the inlet to the chamber, of a valve consisting of a body having wings forming gas-passages, a disk secured to the body and to seat within the gas-'chamber to prevent the escape of gas through the said gas-passages said disk having an open eye or loop, a second disk separated from the lower side of the body whereby the lower ends of the gas-passages are normally open to reeeive gas from the main inlet, said lower disk seating upon and closing the entrance to the lower gas-passage, and means for operating the valve ineludinga pair of levers one loosely and movably connectedwith said eye or loop and the other connected with the diaphragm and also connected with thefirst-named lever at a point between the ends of the latter.
