Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
153 words
A dimension checking tool comprising: An elongated handle; a base portion positioned at one end of the handle, and including a curved outer surface; a measuring rod slidably engaged within the elongated handle for longitudinal movement with respect to the elongated handle and extending from one end of the elongated handle; a trigger mechanism directly coupled to the measuring rod and extending transversely outwardly from the elongated handle for permitting manual longitudinal positioning of the measuring rod; caliper means comprising first finger means fixed for longitudinal movement with the measuring rod and second finger means nestably engageable with the first means and fixed to the one end of the elongated handle, both of said finger means being formed to extend longitudinally and transversely away from the elongated handle; and wherein the measuring rod also extends from the other end of the elongated handle, terminating in a curved end portion adjacent the base portion.
