  • Apparatus for determining specific gravity and density
    Patent number: 4770041
    Abstract: Apparatus for weighing a specimen while suspended in water to determine its specific gravity. A scale is mounted on a table. A rectangular frame having legs surrounding the scale is supported on the table. A liquid filled container is supported directly on the rectangular frame. A second rectangular frame having legs supported directly on the scale has its legs extending through the top of the first mentioned rectangular frame without contact with the top. A specimen is suspended by suspension means from the top of the second rectangular frame to the liquid in the container so that its weight and that of the second rectangular frame and suspension means are the only weights borne directly by the scale.
