Abstract

An improved circumference measuring device of the type comprising a tape curved to form a closed loop with the tape ends being attached to mounting members resiliently biased away from each other to tend to tighten the loop. A cam and follower system operates on one of the mounting members to move the mounting members closer together against the bias for insertion of a rod to be measured and then allow the mounting members to move apart to tighten the loop around the rod. Means responsive to the distance apart of the mounting members indicates the size of the loop and thus of the rod being measured and an automatic control system operates the cam so as cyclically to move the mounting members and adjust the loop between relaxed and rod-gripping and measuring conditions.
