Abstract: A gauge mounting device (20) for an improved mounting a gauge (17) to an instrument panel (19) including an annular gauge bracket assembly comprised of a gauge bracket having an inner tapering thread profile forming a helical pitch, a gripper ring disposed within the inner tapering thread profile having a plurality of gripping teeth radially aligned on a inner surface of the gripper ring and freely moveable along the inner tapering thread profile. The gauge bracket engaged onto a conical or cylindrical gauge housing having a gauge disposed therein and preventing further rotation of the conical gauge housing forming a stationery helix. The gauge bracket rotated causing forward movement by the helical pitch traveling along the stationery helix from the gripper ring resulting in increasing gripping force applied to the conical or cylindrical gauge housing and increasing sandwiching force between the gauge bracket and the conical or cylindrical gauge housing.

Abstract: The invention contemplates a liquid-level sensing transducer having a baseplate which is adapted to removably secure the same to close an opening in a tank within which liquid level is to be measured by noting the angle of a pivoted float arm. A pivot-bearing mount of insulating material is secured by two spaced bolts to the baseplate, and this mount establishes two spaced parallel planes of support which are perpendicular to the pivot axis. A conductive plate is mounted in one of these two planes, and an electrical-resistance element is mounted in the other of these planes. A float-arm pivot member is rotatable in the pivot-bearing mount and includes a radially offsetting arm which sweeps the space between the parallel planes. The offsetting arm of the pivot member supports a moving-contact element in resiliently loaded wiping contact with the conductive plate at one end and with the resistance element at the other end.
