\IMPROVEMIENT'INCURRENT-INDICATORS. 1
Specification forming part of Letters Patent N0. 177,840, dated May 23, 1376; application filed r April15,1876. r
To all whom itmag concern I cBe it-known that I, B NJAMIN W. HoxiE',
. .of Hartford, in the county of Hartford and State of Connecticut, have invented certain new anduseful Improvements pertaiuingnto a t Current Indicator, of which thefollowingis a specification, reference being bad to the 'accentrat longitudinal vertical section. Fig.3 is an end View." 7 I This device is intended for insertion inthe feed-water pipe leading iiitoa-steamboiler, to X denote whether the feed-pump is. working properly and forcingacurrentof water through the-pipe into the boiler. IIt-is also intended for other analogous uses', whereit.is desired to know whether a current is flowing through It has a'valve-body, a, with interior screwthreads. at the ends, whereby, to connect to the pipe. There is hung within thebodythe swingingvalve b, filling or about filling the aperture at that point. The shaft c.'uponwhich this valve is hung, rotateswith it, and projects through the side of the body a, coming out through the stuffing-box d, and hearing the cam e, on which rests the broadened foot f of the pillar or rod f,sliding or playing in the post g, and, pressed down by the spring h. The shape of the broadened foot f correis a view in sponds to the shape-of the cam e, so that the downwardpressure ot' the spring tends to bringthe' valve bto position to close "the current-aperturerbut the spring is only strong enough to eifectthis action, and not strong enough to obstruct the current. The valve is free to swing either way, so as to denote a current in either direction, as the pipe may be used for contrary currents, and it may be desired to know which way the current is flowing. The shape of the cam corresponds to this double action.
going that when no current is flowing, the cam will stand in the position represented in Fig. l, but that a passing current will raise the valve and correspondingly tilt the cam, and. show the direction and amount of the-cur.-
.rent. If desired, (and I have so proposed,) an
index-finger can be attached to the outer end of shaft 0, moving over the face of a graduated dial, to more accurately indicate the amount of the current.
I claim as my invention' In combination, valve 12, with its shaft 0, cam e, and spring-pillar f, all substantially as described, and for the purposes set forth.
