Adapted located one at each side of the supporting-pin to seat itself in the seat D is a valve E, se- J are two vertical rods R, the upper ends of 100 cured to the lower end of a vertical valvewhich are connected by a horizontal rod S,

stem F, which extends through the axial cenupon which is mounted a longitudinally-slidable balance-weight '1, adapted to be secured at any desired position upon the rod S and by means of which the proper adjustment for operating the machine is secured. This con struction enables one to move the weight T to the right or left of the fulcrum-point of the lever I, thus throwing the weight of the counterbalance with or against the weight of the float N and provides a wide range of regulation of pressure of the gas passing into the service-pipes.

My invention is operated as follows: The regulator is first secured, by means of the pipe 0, to thepipe leading from the meter, and

the pipe Q is connected with the service-pipes.

Gas then being admitted will cause the float N to rise, thus elevating the left end of the lever I and depressing the right end thereof, forcing the valve-E toward the valve-seat D and tending to close the same and shut off the gas. Any closing off of the passage of gas out of the pipe Q will increase the pressure of gas within the casing below the float N, causing it to rise, and thus close the entrance in the pipe C, while the contrary effect will be occasioned by letting out more gas through the pipe Q. When it is desired to take out the working parts for cleaning, it is but necessary to remove the cover B from the casing, after which the float N, sealing-cup P, and all parts connected therewith may he removed by disconnectin the ends of the supporting-arms K from the casing-wall, the diameter of the valve E being smaller than the distance between the inner sides of the tubular wall G. It will be noted that all the operative parts outside of the valve E are located outside of the part of'the casing in which the gas is contained, and therefore the working parts are free from ,the injurious deposits fromthe gas, rendering the regulator not liable to the causes of disorder to which this class of regulators is usually exposed. It will also be noted that in the construction of the regulator no part is formed so as to provide a trap adapted to catch condensed products of the gas, but that all such matter forming in the service-pipes will pass through the pipe Q into the casing, from which it will pass into the meter through the valve-opening in the pipe 0.

My invention is capable of many n1odilications without departing from its spirit.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is p 1. In a gas-regulator, the combination with the casing comprising an upper and a lower chamber, the lower chamber being provided with inlet and outlet openings for the passage of gas and the two chambers connecting through two tubular walls around which is adapted to be retained a sealing liquid, of a valve controlling the gas-inlet opening, a float encircling one of the said tubular walls and connected therethrough to the valve, a float encircling the other tubular wall, and a lever pivotally supported above the floats and connected thereto at its ends, substantially as described.

2. In a gas-regulator, the combination with the casing inclosing two chambers one an airchamber and the other a gas-chamber, the gas-chamber being provided with gas inlet and'outlet openings, and two openings connecting the two chambers, of two suitablysealed floats closing the said two openings respectively, a lever pivoted in the air-chamber between the two floats to which itis connected atits ends, and a valve controlling the gas-inlet opening and operated by the movement of the said lever, substantially as described.

3. In a gas-regulator, the combination with the casing inclosing two chambers, one an air and the othera gas chamber, the two chambers being connected by two openings and the gas-chamber provided with gas inlet and outlet openings, of two suitably-sealed floats closing the two openings respectively, a lever connected at its ends with the two floats respectively and pivoted to a suitable support located in the air-chamber, a valve controlling the said gas-inlet opening, and a rod extending through one of the two openings connecting the two chambers and connecting the lever with the valve, substantially as described.

l. In a gas-regulator, the combination with the casing inclosing two chambers, one an air and the other a gas chamber, the gas-chamber being provided with gas inlet and outlet openings, and the two chambers being connected by two openings, of a valve controlling the gas-inlet opening, a float closing one of the openings leading from the gas-chamber to the airchamber, a rod extending through the other of said openings and connected at one end with the said valve, a lever pivoted in the air-chamber and connected at one end with the other end of the rod and connected at the other end to the said float, a float carried by the rod and closing the opening in which the rod is located, and means for preventing the passage of gas around the two floats into the air-chamber, substantially as described.

5. In a gas-regulator, the combination with a gas-chamber provided with an inlet and an outlet opening, of a valve controlling the said inlet-opening, two openings leading from the gas-chamber to the outside thereof, two suitably-sealed floats closing the said two openings and subjected always to the same gaspressure relatively, a lever connecting the two floats, and means by which the move ment of the floats is made to operate the said valve, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.
