GAUGE FOR FLUIDS IN TANKS Original Filed April 22, 1955 INVENTORS MICHAEL SKI/ 57 JOH/V SEKULA ATTORNEY Patented Jan. 12, 1937 UNITED STATES PATENT OFFICE ApplicationApi-il 22, 1933, Serial No. 687,364 Renewed July 16, 1935 This invention relates to new and useful improvements in a gauge for fluids in tanks.

The invention has for an object the construction of an article as mentioned which is charac-' terized by a longitudinal casing with a side opening supporting in fixed relation a transparent tube viewable through the opening and an arrangement for holding a fluid 'within the tube after its insertion within a fluid tank.

Still further, the invention contemplates constructing the casing from a pair of opposed longitudinal side elements joined by a plurality of rings spaced along the length of the casing.

Still further, the invention contemplates the provision of a cup-shaped valve slidably arranged upon the bottom of the casing and connecting with an operating rod extending through the transparent tube to the upper end of the casing.

As another object of this invention, an arrangement is contemplated whereby additional casing material and additional rod material is adapted for connection respectively with the casing and rod of the device so as to extend its length to adapt it for tanks of different heights.

Another one of the objects of this invention is an arrangement in conjunction with the cupshaped valve for preventing excessive disturbance of the fluid when the gauge is inserted therein.

In particular; the objects mentioned in the previous paragraph, to be accomplished by the provision of a disc valve operating in conjunction with the cup-shaped valve and operated by rota.- tion of said rod.

A still further object of this invention is the construction of an article as mentioned which is 1 simple and durable and which may be manufactured and sold at a reasonable cost.

Forfurther comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. is a horizontal sectional view taken on the line 5--5 of Fig. 4';

The gaugefor fluids in tanks to which this in- 5 vention is to apply, comprises a longitudinal casing consisting of a pair of opposed side elements grooves in the sides so as to form a neat construction, in which each of the longitudinal sides III is positively held against longitudinal motion.

The arrangement of the longitudinal casing is such that it is substantially formed with side longitudinal openings, that is, the space between the adjacent sides of the members Ill through which the transparent tube ll may be clearly viewable. The tube ii is arranged longitudinally within the casing and held in a relatively fixed position by the clamping action of the sides of I the casing. 'A red I3 is extended through the transparent tube I I and at the upper end is provided with a head It by which it may be conveniently moved.

A cup-shaped valve I5 is mounted upon the lower end of the rod l3. This cup-shaped valve is formed with an upper ring portion it which slidably engages upon a reducedend l1 formed on the longitudinal casing. The graduated scale 2| is inscribed or in any other manner formed upon the transparent tube ll so as to give the heights of'contained liquid.

it means is provided for holding the cup-shaped valve in the opened or in the closed position. This means comprises a spring 22 attached upon the longitudinal casing within the hollow thereof and frictionally engaging against the sides of the rod l3. The arrangement is such that the cupshaped valve may be moved to an opened or closed position and this position maintained by the action of the spring.

In Fig. 3, a further application of the device has been disclosed in which provision is made for adding additional sections upon the device so that it is operative for tanks of greater height.

More particularly, a collar 23 is fastened upon ,3 the upper end of the longitudinal casing and is formed with a. threaded portion 24 adapted to be engaged by a tubular member 25 which necessarfly extends the operative length of the casing. similarly, an auxiliary rod 26 engages within the an threaded opening formed in the head It for extending the operativelength oi the rod I3. With the extended unit, its operation is similar to the operation described. First, the rods 26 and I3 must be adjusted so as to open the cup-shaped valve in the bottom of the device and thereaiter,

the casing moved downwards so as to close the bottom end oi the tube against the seat of the valve.

Provision is made so as to reduce to a minimum agitation of the fluid within the tank when the device is inserted according to this invention. More particularly, a plurality of openings are formed in the bottom of the cup-shaped valve and an additional valve provided for closing these A collar 3| is fixed upon the rod l3 immediately extended through the seat is inserted down above the seat of the cup-shaped valve so as to hold the rod rotative relative to the cup-shaped valve. The cup-shaped valve ii is provided with a seat washer 20. A plurality of openings 32 are 20 in the bottom of the valve i5. The disc valve 30 is formed with similaropenings 33 adapted to register with the openings 32 in one position. This action provides for the opening and closing of the discshaped valve.

The openings 32 are arranged within an area bounded by the periphery of the transparent tube II, when the tube is in contact with the valve of the seat. Other openings 34 outside of the periphery of the tube Ii are also provided which extend through the seat washer 20 and the bottom of the cup-shaped valve it. These openings 34 register with elongated openings 35 formed in the disc valve 33 so that in all positions of rotation of the disc valve passage through the openings is unrestricted. A peg 35' projects from the bottom of the cup-shaped valve i5 and extends into an accurate peripheral recess 36 formed in the disc shaped valve 30 so as to limit rotation thereof through approximately more particularly from a position in which the openings 32, 33'

are in alignment to a position in which they are out of alignment. The angular motion of the disc-shaped valve 30 depends upon the distance between the openings 32.

The operation of the device will be readilyunderstood from the description, but it is pointed out that first the rod i3 should be adjusted so that the disc valve 30 is opened in addition to the cupshaped valve l5 being opened. Then the device into the fluid oi the'tank. As the device moves downward, thefluid may pass out through the openings 33, 32, 34 and 35 and so insure a good sample for the gauge. After the cup-shaped valve l-i' strikes the bottom of the tank, the longitudinal casing'should be moved downwards so as to close the cup-shaped valve and entrap the sample. Then the rod i3 should be turned by turning the head piece ll so as to close the disc valve 30. The gauge may then be removed and the sample inspected.
