Abstract

An elongated transparent tube of plastic is mounted at one end in a base member by which it is held in an upright position. It has a flared out funnel shaped top to ease pouring liquids thereinto and at its lower end an aperture through its wall just above its end where it is mounted in the base member. A plug having an axial extending passageway therethrough is received in the upright tube and secured therein in a desired position spaced down from the funnel shaped top end. The spacing of the plug provides a receptacle for a measured amount of urine or liquid whose specific gravity is to be measured or it may be used otherwise. A plastic transparent flexible tube extends from within the axial aperture of the plug downwardly through the upright tube and out through the aperture in the wall thereof just above the base member. There is a lever pivotally mounted at one end in a post extending up from the base which extends across and in contact with the flexible tube and on pushing the lever down the walls of the tube are pinched together against the adjacent top surface of the base. This serves as a valve to close off and open up the flow through the flexible tube to drain the measured amount of urine or liquid. A midget hydrometer is placed in the captive liquid to measure its specific gravity. Other tests may also be made on the captive liquid.

Primary Examiner-Robert M. Reese Attorney, Agent, or Firm-Jones, Tullar & Cooper [57] ABSTRACT An elongated transparent tube of plastic is mounted at one end in a base member by which it is held in an upright position. It has a flared out funnel shaped top to ease pouring liquids thereinto and at its lower end an aperture through its wall just above its end where it is mounted in the base member. A plug having an axial extending passageway therethrough is received in the upright tube and secured therein in a desired position spaced down from the funnel shaped top end. The spacing of the plug provides a receptacle for a measured amount of urine or liquid whose specific gravity is to be measured or it may be used otherwise. A plastic transparent flexible tube extends from within the axial aperture of the plug downwardly through the upright tube and out through the aperture in the wall thereof just above the base member. There is a lever pivotally mounted at one end in a post extending up from the base which extends across and in contact with the flexible tube and on pushing the lever down the walls of the tube are pinched together against the adjacent top surface of the base. This serves as a valve to close off and open up the flow through the flexible tube to drain the measured amount of urine or liquid. A midget hydrometer is placed in the captive liquid to measure its specific gravity. Other tests may also be made on the captive liquid.
5 Claims, 2 Drawing Figures 1 URINOMETER SUMMARY OF INVENTION It is desired to provide a container that is mounted in an upright position for a relatively small sample of urine or liquid whose specific gravity is to be measured with a midget hydrometer or on which other tests are to be carried out.
This container is to be arranged so as to be drained without having to stop and pour out the liquid and this results in fewer spills being encountered.
Ease of filling of the receptacle is enhanced by providing a flared funnel shaped filling opening.
The receptacle is to be transparent and mounted in an upright position on a stable base and have a drain hose with an easily operated valve therein.
The apparatus with its gravity flow and easily operated cut off valve affords faster testing of multiple samples.
Other features and advantages of the invention will become apparent upon reading the attached detailed description, and upon reference to the drawings, i;n which:
FlG. l is a perspective view of the preferred embodiment of the urinometer and FIG. 2 is a modified form of the urinometer with the drain tube and cut off valve changed.
The testing apparatus in its preferred form is indicated at in FIG. 1. An upright tubular member 11 similar in dimensions to a test tube is preferably of transparent plastic material and is closed off at its bottom end where it is mounted for vertical support in base member 13. The upper filling end 12 of the tube 11 is flared outward in a funnel shape to make filling easier.
Received in the tube 11 is an axially apertured plug 14. It is positioned at a selected distance from the top of tube 11 to provide for the desired volume. Mounted in the axial aperture of plug 14 is the upper end of a flexible plastic tube or conduit 15 which extends downward in tube 11 and out through an aperture 16 in the wall of tube 11 adjacent the bottom end.
A shut off valve for the flexible tube 15 is generally indicated at 17 and is mounted on base 13. The valve 17 has a mounting post 18 mounted on base 13 and it is slotted at 18a to receive the end of a lever 19 that is vpivotally mounted on the post 18 by a pivot pin 18b.
upper end of tube 11 to measure the specific gravity of the liquid such as urine.
In FIG. 2 like parts of the measuring device of FIG.
7 l are shown in a modified form of the device. The vertiand thumb operated typical laboratory tube clamp 20.
This test apparatus for conducting various test of liquid samples such as the specific gravity of urine provides for gravity flow emptying. It affords rapid testing of multiple samples.
