GAGE.

Specication of Letters Patent.

Patented Mar. 25, 1919.

To all whom it may concern:

Be it known that I, BENJAMIN WEBSTER, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Gages, of which the following 1s a specification, reference being had therein to the accompany l detached;

Fig. 2 is a cross section;

Fig. 3 is a longitudinal section; and

Fig. t is aY plan.

A is a disk cover, which may be constructed to fit within the lill opening B of the liquid fuel tank or other apparatus in which the gage is employed; C, is an aperture in the disk A; D are ears depending from the disk at opposite ends of the aperture C, being preferably formed with angle flanges E spot-welded or otherwise secured to the disk; Fis a pivot pin passing through and between the ears D; G is a float-arm preferably formedy of wire and having a coil H surrounding the pin F; and I is a segment concentric with the pin F and suitably secured to' the arm G, preferably by a twopoint engagement. As specifically shown, the arm G extends in the central plane of the segment and passes through an aperture adjacent to one end thereof, being then oif.

set at J to one end of the coil H, while from the opposite end of said coil is an extension of the wire o`set at K to the central plane of the segment and engaging the opposite end thereof at the point L. This will se' curely fasten the segment to the arm and vwill maintain the same concentric with the pin F. The upper end of the segment has an outwardly-bent portion' M which contacts with the lower lface of the disk A and operates as a stop to limit ,the swinging movement of the arm'.

' The mechanical construction being as thus far described, to eifect the indication 'a spiral index N is marked or otherwise formed on the outer face of the segment I, and upon the disk A adjacent to one edge of the aperture C are suitably calibrated markings. Thus, whenever the arm G is rocked bythe actuation of the fioat (not shown) the segment I will be correspondingly rocked and will display a different-portion of the spiral N through the aperture C adjacent to the calibration on the disk A. Each point of adjustment will produce a different position of the index in relation to the scale, but in every case the line is clearly displayed, so that a reading can be easily taken.

One advantage of the construction is the \simple mechanical movement which does away with the necessity of` gears or any other translating devices for chan 'ng the direction of the motion. Also the act that the pin F is the only fulcrum avoids dan er of the sticking or binding of parts which might render the indication inaccurate. Another advantage is the low cost of manufacture, and still another the fact that the gage may be inserted in the fill opening ofA the tank or liquid holding rece tacle and may be readily withdrawn there rom Whenthe tank is to be re-illed. To facilitate thisv withdrawal I preferably provide struck-up ears O formed from the metal removed from the aperture C, these forming convenient grips for the thumb and finger 1n lifting out the gage.

The arrangement of the stop M at one end of the segment, which by contact with the disk A limits the swinglng of the arm G, prevents inoperativev arrangement of the 'gagemechanism in the liquid tank. Thus without such a stop there would be the possibilitv of the iioat arm being arranged to extend in the opposite direction so that the indicating segment would be reversely operated, but with the stop the arm is held at an angle wherethe vrising of the liquid will always cause the correct indication.

' hat I claim as my invention is:

l. A gage, comprising an apertured late or dial, a pivot bearing depending t erefrom, a cylindrical segment having a spiral index thereon cooperating with markings on said plate adjacent to said aperture, and a member engaging said pivot bearing having a portion extending in one direction from forming a float arm.

said bearing forming a support for said segment and in another direction therefrom 2. Agage, comprising an apertured plate or dial, a pivot bearing depending therefrom, a cylindrical segment having a spiral index thereon, and a float arm pivoted in said bearing, secured to said segment and forming the actuating means therefor.

3. A gage, comprisin an apertured plate or dial, a depending pivot bearing on said plate, a pin engaging said bearing, an arm having a coiled portlon engaging said pin,

and a segment secured to said arm and rocked thereby adjacent to said aperture.

4. A gage, comprising an apertured dial .or plate, a depending pivot bearing on said plate,` a wire rock-arm having a transversely-extending coiled portion and portions extending longitudinally on opposite sides of the coll, a pivot pin engaging said coil and bearing, and a segment mounted on said arm and extension thereof and rocked thereby adjacent to said aperture.

5. A gage, comprising a plate or dial having an aperture therein and lugs struck up from the material removed from said aperture forming` thumb and -finger grips, a pivot bearing depending from said plate, a rock-arm pivoted to said bearing, and a -or dial, an arm pivotal vable segment secured t ereto, an apertured plate through which said segment may be vviewedfand a projection from said segment at one end thereof for impinging against said plate to form a stop for limiting the swinging of'said rock-arm in one dlrection. 40

7 A gage comprising` an apertured plate supported by said plate, a oat carried by said arm and a segment secured to said arm 'and rocked thereby adjacent to said aperture. f

8. A gage comprising an apertured plate or dial, an arm having a coiled portion, a pivotal support for said` arm carried by said plate and engaging the coiled portion thereof, and a segment secured to said arm and rocked thereby adjacent to said aperture.

. 9. A gage'comprising a rock arm and f rockable segment secured'thereto, an apertured plate through which said segment may be viewed, and means limiting the rocking of said segment in one direction.

In testimony whereof I airix my signature.

BENJAMIN WEBSTER.
