Abstract
Abstract Repeated measurements of similar values with rapid speed are achieved by link means connecting a rigid frame freely mounted to slide on the bar of a caliper and a vernier plate slider, screw means which sets the position of the rigid frame on the bar of the caliper, means which resiliently biases the vernier plate slider away from the rigid frame and reading means actuated by relative movement between said frame and vernier plate slider.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
In a snap caliper comprising a bar, a stationary jaw at one end of said bar, a movable jaw slidably mounted on said bar, a frame slidably mounted on said bar on the side of said movable jaw remote from said stationary jaw, and manually operable means for holding said frame in a fixed position on said bar, the improvement which comprises: resilient means carried by one of said frame and said movable jaw lying on diametrically opposite sides of said bar and each positioned to bias said movable jaw away from said frame, an indicator comprising a pivotally mounted needle carried on said frame, and a rack mounted to move with said movable jaw and drivingly engaging said indicator to swing said needle when said movable jaw moves relative to said frame.
