IMPROVEMNT ISN Cl'RCULATlN'G-VALVS FOR FIRE-ENGINES.
Specification forming part of Letters/Patent No.140,l911, dated June 24,1873; application filed April 26,1873.
To all uhom it may concern:
Be it known that 1, CHARLES A.. BAGUE,
of Hudson, in the county of Columbia and State 'of New York, .have invented a new and Improved Circulating-Valve forvStearn Fire- Engines, ot' which the following is a specification: Y
Figure l is a sectional elevation ot' a circa lating'tvalve, which I propose foruse in reengines, to relieve the hose-of pressure when the pipe-man shuts oi the escape at thenozzle. Fig. 2 is a horizontal vsection on the line w a: of Fig. l; andFig. 3 is a horizontal 'section on the liney y. L
SimilarV letters o' reference indicate corresponding parts.`
The case O is attached to the dischargev .chamber of a tire-engine by the screw X, and
pipe gis attached with the-suction. When the pressure rises in the discharge by the shut-tin g l bit otlthe escape, the water, actingon small valve'-an, lifts it against spring C, and acts on the top f, the area of which is greater than the valve S, which is thereby forced down and -lopeus the passage y, through which vthe water escapes from the discharge to the. suction, and thus relieves the pressure in the hose. The valve S is held up, when not subject to water-pressure, by the spring h. The tension of spring C is regulated by the hand'- wheel aV audits stem, which screw the cap-nut b up or down on tube J, which is prevented from turning by the lugs l.' The opening of-A valve S may be adjusted for different pressures or diiierent pumps by lplaein g washers bel tweeuthe case of spring C and cap l?, on case K, on which it strikes, or by adjusting said cap up or down by suitable means also, the construction of valve f is such that the extra rises i'sv balanced by corresponding surface on back side, causing the valve S toscat itself as soon as the pressure falls below that which raised it.
This device is' -fmore instaptaueouscn ,action tlian'a relief valve, which has to be opened against a spring, because the power of the and spring h, substantially as specified.

spring increases as the valve rises, ,whereas in this case as soon as the valve S has'opened. a little there is no resistance, except by the .3. The arrangement of springC, adjusting cap-nut b, hand-wheel a, tube J the valve m,
