UNITED STATES PATENT OFFICE.
TREAT T. rnossna, or CHICAGO, ILLINOIS.
IMPROVEMENT IN RELIEF-VALVES.
Specification forming part of Letters Patent No. 165,]. 19, dated June 29, 1575; application filed March 1, 1875.
To all whom it may concern:
Be it known that I, TREAT T. Pnossnn, of
Chicago, in the county of Cook and State of Illinois, have invented a Safety- Valve, of which the following is a specification, reference being had to the accompanying drawing, which forms a part hereof. My invention consists in the combination of the valve and spring, as hereinafter fully described, by means of which the tension of the spring is regulated, so as to hold the valve to resist a certain pressure.
In the accompanying drawings, Figure 1 represents a side elevation of my satety-valve; Fig. 2, a transverse sectional view taken at the line :20 x in Fig. 3. Fig. 3 is an end eleva- 1 tion.
' which pass through the valves E, and screw into the cores. The ends of the spiral spring G are fastened to the cores F, into which the screws H screw.
It will be observed that byturning the screw H the tension of the spiral spring G is varied, and the pressure of the spring to hold the valves closed is regulated. The pressure within the pipe will not open the valves or the couplingoint ot' the hose used for throw ing water by steam-engines. The tension applied to the valves may be regulated, so as to admit of the escape of water, and prevent the hose from bursting. It may also be applied in all of the places where a steam safety-valve isrequired.
I claim- The combination of the valves E, arranged opposite each other within, the coupling, and spring G, as and for the purpose specified.
TREAT T. PROSSER.
