Abstract
Abstract An inclinometer test assembly comprising a horizontal base plate, a vertical column mounted on the base plate, a support arm pivotally mounted intermediate its ends on the column, the arm having a longitudinally extending recess for receiving the cylindrical body of an inclinometer therein for the purpose of testing the inclinometer, a finger-like clip securing the inclinometer body within the recess, a three-point adjustment for the leveling of the base plate, a pointer plate and a degree plate mounted on the arm and column, respectively, for the positioning of the arm at a predetermined angle relative to the true vertical in order to test the inclinometer.

Claim 1
Independent Claim
159 words
An inclinometer test assembly comprising a horizontal base plate, a vertical column affixed to said base plate, a support arm pivotally mounted intermediate its ends on said column, said arm having a longitudinally extending recess for receiving the cylindrical body of an inclinometer therein for the purpose of testing said inclinometer, means for securing said inclinometer body within said recess, means for leveling said base plate, and means for maintaining said arm in predetermined known positions relative to the true vertical, said pivotal mounting for said arm comprising a pivot shaft rotatably received in said column, said pivot shaft having one end affixed to said arm having an opposite end extending outwardly beyond said column, said means for maintaining said arm in predetermined positions comprising a clamp with a thumb screw extending through said clamp, said opposite end of said shaft being received in said clamp and being frictionally engaged by said clamp upon tightening of said thumb screw.
Claim 2
Dependent Claim
