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.

surface, exposed to pressure 'when valve m,
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,
