HERMANN PIETSOH, OF MILWAUKEE, WISOON SIN.
IMPROVEMENT IN CARBONlC-AClD-GAS GENERATORS.
Specification forming part of Letters Patent No. 155,041, dated September 15, 1874; application filed July 10, 1874.
To all whom itmay concern Be it known that I, HERMANN PIETSCH, of Milwaukee, in the county of Milwaukee, in the State of Wisconsin, have invented certain Improvements in Check and Safety Valves for Oarbonic-Acid-Gas Generators, of which the following is a specification:
My invention has for its object the keeping the water from flowing from the washer into the generator, and for the safety of the generator by a safety-valve, and is accomplished by placing a check-valve in the pipe which leads from the generator to the washer, so that when a vacuum, or partial vacuum, is produced in the generator the water shall not flow over from the washer into the generator,
ings are sunk outside of the valve-seat, and then opening out through the valve-case E, a cover of some flexible material over the opening in the valve-seat, and pillows to the sides of the valve-chamber, so that when the valve is raised the gas may not reach and corrode the spring which holds the valve down F, the valve; G, a spring round the valve stem, which, pressingagainst the valve and the cover of the valve-chamber, holds the valve onto its seat, the stem of the valve passing up through the cover; H, cover of the valve-chamber; I, check-valve seat and opening for the gas to pass through; K, the valve,
made of any material, and hung above the seat; L, the pipe, which passes from the generator to the washer; M, top of a carbonicacid-gas generator, showing the connection of the valve-case thereto only; N, top of-a washer, merely to show the connection of the pipe L thereto.
The operation of these valves is as follows: When the gas is generated in the generator, it passes, through the valve-cover, into the washer, the check-valve opening freely to let it pass; but if there is a vacuum in the generator the valve is closed by the action of the gas in the washer, and it cannot, nor can the water in the washer, pass back to the generator, and when there is too much pressure in the generator the safety-valve will be opened, and the gas will escape.
I claim as my invention- Valve-case A, having the safety-valve B and check-valve I, substantially as specified.
HERMANN PIE'ISGH.
