AUTOMATIC iViESURlNG-TAN K.

SPECIFICATION forming part of Letters Patent No. 716,539, dated December 23, 1902. Application led May 1,1901. Serial No. 58.369. (No model.)

.T afl/ whom it may concern:

Be it known that I, JOSEPH E. HARTMAN, a

citizen of the United States, residing at Clevefluid is drawn from the tank as required and in predetermined quantity and automatically shuts off when the required quantity is delivered.

The object of my invention is to provide a iiuid container or tank which is provided with a vertically-adjustable intake, which is lowered the necessary and predetermined distance beneath the liquid-surface in the tank to allow of a certain and predetermined amount of liquid to be delivered through said intake and from thence pass out of the container or tank and into a portable can or the like. A11 adjusting device is also provided for raising and lowering the intake, and a registering device or index is connected, whereby the measuring is accomplished.

In the drawings, Figure I is a view in elevation of a tank constructed according to my invention. Fig. II is a vertical sectional View of the tank, illustrating its internal construction. Fig. III illustrates my preferred construction of mechanism for operating the intake. Fig. IV is a sectional view of a valve mechanism employed to prevent leakage through the intake. Fig.Villustrates a modified form of faucet, which is adjusted vertically; and Fig. VI illustrates a sectional View of my improved dial or pointer.

A represents a casing which is formed into two compartments-viz., an upper compartment A', which is adapted to contain the duid, and a lower compartment A2, which supports the compartment A' and also acts as a chainber for receiving and protecting the delivering-pipes and a portable utensil to which the liquid is delivered.

B represents the mouth of the intake, which is preferably formed funnel-shaped and communicates with the adjustable intake-pipe B', upon the upper end of which said mouth B is mounted. The intake-pipe B' telescopes within tube C, with which it forms a fiuidtight slip-joint, so as to adapt said pipe B' to be raised or lowered, and 'with it the intakemouth B.

My preferred mechanism for raising and lowering the intake-mouth B and pipe B' consists of a vertical rack D, which is attached at the lower end to the intake-mouth B or pipe B', and a pinion D', mounted on a spindle D2 and meshing with said rack D.

E represents a bearing-block which forms a bearing for spindle D2 and a guide for the rack D. (Seen more-clearly in Fig. III.)

f represents a valve which is adapted to seat itself upon the upper end of the intakepipe B' and close the same tightly. The valvef is in turn secured in a suitable manner, such as by means ofan arm f', to an annular cork float F, which is hinged at one side in the intake-mouth B, (see Fig. IV,) thus allowing said valvefto open when the mouth B is between the surface of the duid in the container or tank and to close when the surface of the Iiuid has reached the upper rim or surface of the intake-mouth B, as will be hereinafter described.

In Figs. I and VI, I have illustrated my improved dial and pointer, which is especially adapted to indicate and predetermine the amount of iiuid which is to be drawn from the container or tank, and the sameis constructed as follows:

G represents a pointer which is secured to spindle D2 in such a manner as to rotate said spindle and with it the pinion D'. The pointer G is formed in two parts, one, g, of which is slidable within the other. The part g is provided with a projection g', which slides in an opening or slot formed in the part g and engages a spiral way or run h, formed on the face of the dial H, and thus is projected or retracted according to the direction in which the pointer Gis rotated. Divisions and marks h' are formed on the face ofthe dial and arranged so as to indicate halfpints, pints, quarts, and gallons or the like quantity of fluid measure. These marks are arranged in a spiral to correspond with the way or run h, so that the indicating end of the pointer will follow a spiral path.

The pipe C extends downward, as illustrated in Fig. II, and from thence upward and outward by branches C and C2, respectively. The ,horizontal pipe C2 is turned downward and provided with a -faucet C3, which forms the outlet for the fluid measured off within the tank by lowering the intake-mouth B. Avertically-adjustable eX- tension C4 may be provided at the outlet end of the faucet C3, said extension being funnelshaped at its lower end, so as to enter narrow-necked bottles, cans, or jars.

The operation of my device is as follows: The tank A being supplied with a suitable quant-ity of fluid, the intake-mouth B being raised above the level of the surface of the fluid, the mouth B of the intake is now lowered, so that its upper end will be just level with the surface of the fluid in the tank and the dial I-I and pointer G set at zero. When it is desired to draw off a certain quantity of fluid, the intake-mouth B is lowered the required distance beneath the surface of the liquid in the tank by turning the pointer G along the face of the dial to the required mark on its face. The faucet C3 being closed the air in the pipe C will force the valve f open until the required amount is delivered from the tank by opening the faucet C3. When the surface ofthe fluid in the tank has reached the level of the upper end of the intake, the iiuid stops flowing and the valvef closes automatically and stops any drip through the faucet C3.

The object in forming the dial with aspiral guide-run h and spiral marks for causing the pointer to indicate different quantities is to prevent mistakes in measuring on account of the different cross-section areas of the container or tank at different levels.

What I claim isl. In a measuring device of the type set forth, the combination with the tank or container divided into an upper liquid-receiving compartment and a lower compartment to receive a delivery-pipe, of a vertically-adjustable intake-pipe communicating with said tank and telcscoping with said delivery-pipe, a flaring mouth carried by the upper end of said intake-pipe, an annular iioat hinged to the inner Wall of said mouth, and a valve connected to the oat by a spring, said valve adapted to normally close the inlet to the intake-pipe.

2. In a measuring device of the type set forth, the combination with the tank or container divided into an upper liquid-receiving compartment and a lower compartment in which latter a deliverylpipe is arranged, of a 'riesce vertically-adjustable intake-pipe having a mouth at its upper end, a iioat hinged within said mouth, a spring-held valve carried by the oat and normally closing the inlet to the intake-pipe, and means for adjusting and determining the adjustment of said intake-pipe, substantially as described.

3. In a measuring device of the type set forth, the combination with a vertically-adjustable intake-pipe, a tank or container divided into an upper and a lower compartment, the upper compartment to receive the liquid and within which said pipe is adjustable, a float located at the upper end of said intakepipe, and a spring-held valve carried by said float for normally closing the inlet to the intake-pipe, substantially as described.

4. In a measuring device of the type set forth the combination with a tank or container of an adjustable intake-pipe having a mouth secured to its upper end, an annular ioat hinged within said mouth, a spring-held valve carried by the float and normally closing the inlet to the intake-pipe, means conveying the liquid from said intake-pipe and delivering the Same, and means for regulating and determining the adjustment of said pipe substantially as set forth.

5. A dial and pointer for measuring devices of the type set forth, comprising a dial-plate havingl spirally-arranged indicating-marks, a spirallyarranged way on the dial-face, and a pointer made in two sections G, g, the latter telescoping in the former and having its inner end turned at an angle to engage in the spiral way and travel in a slot provided therefor in the section G, whereby the telescoping section g of the pointer is forced outward or drawn within the section G, a shaft on which both dial-plate and section G of the pointer is mounted, and means for rotating the shaft and pointer in unison, substantially as described.

6. In a measuring device of the type set forth the combination with a tank or container of a vertically-adjustable intake-pipe connected to a rack and having a mouth at its upper end, a float carried by the mouth, a valve carried by the float for normally closing the inlet to the intake-pipe, and a pinion engaging said rack, with means connected to said pinion whereby the rack and the attachedintake-pipe is adjusted or moved in a vertical direction, substantially as set forth;

Signed by me at Cleveland, county of Cuyahoga, and State of Ohio, this 9th day ofMarch, 1901.
