ABSTRACT:
A device for measuring the volume of objects by use of air pressure includes a container which has a primary rod and a secondary rod, desired portions of which can be controllably disposed in the interior of the container. These rods are graduated so that it is possible to note the degree of penetration of the primary rod into the container and, similarly, the volume of the portion of the second rod in the container. The container is designed to be closed airtight and to hold the object of unknown volume. The primary rod is forced into the container to generate an elevated pressure which pressure is noted. Thereafter, the object is removed and in its place a sufficient portion of a second rod, estimated to equal the volume of the object being measured, is disposed in the container. The primary rod is then repositioned as before with the idea of obtaining the same pressure reading as before. If the same pressure reading is not obtained, the amount of penetration of the secondary rod into the container is readjusted and the primary rod is again inserted to the same degree to obtain the originally noted pressure reading. These steps are repeated until a close enough pressure reading is obtained at which point the volume of the object being measured is determined by noting the degree of penetration of the secondary rod.
