Measurement tool used with an indicator

1. Field of the Invention

The present invention relates to a measuring attachment for an indicator and more particularly pertains to a new measurement tool used with a dow indicator for simplifying the task of measuring a hard-to-reach surface of an object.

2. Description of the Prior Art

The use of measuring attachment for an indicator is known in the prior art. More specifically, measuring attachment for an indicator heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

Known prior art includes U.S. Pat. No. 2,062,961; U.S. Pat. No. 2,199,236; U.S. Pat. No. 2,456,497; U.S. Pat. No. 1,806,893; U.S. Pat. No. 4,809,440; and U.S. Pat. No. Des. 252,501.

While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new measurement tool used with an indicator. The inventive device includes a cylindrical member having a first and a second end and a bore extending therethrough and a first longitudinal slot and a second longitudinal slot; and also includes a shaft moveably disposed in the bore and having a collar securely attached thereabout to limit the movement of the shaft in the bore; and further includes a linkage member pivotally attached to the shaft and moveably disposed in the first longitudinal slot and being pivotally attached to an arm member; and further includes a fastening member securely mounted to the cylindrical member for tightly securing the indicator in the cylindrical member with the shaft being in contactable relationship with the indicator.
