Abstract
Abstract An apparatus for determining a dimension of a member and having a frame, a sensing means on the frame adjacent the member and the sensing means having opposed sensing assemblies aligned adjacent the dimension is disclosed. Each of the sensing assemblies has a housing, a probe reciprocable in the housing and with respect to the member, retraction means associated with the probe and operable to retract the probe to an initial starting position, biasing means connected to the probe for moving the probe from the initial starting position to a measuring position into engagement with the member, and a first signal means associated with the probe and operable to produce a first output signal when the probe is in the measuring position. Indicating means are connected to the sensing assemblies and are adapted to receive the first output signals from the sensing assemblies and to indicate the dimension.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
184 words
Apparatus for determining a dimension of a member, said apparatus having: a. a frame, b. a sensing means on said frame adjacent said member and having opposed sensing assemblies aligned with said dimension, 1. each of said sensing assemblies having: a. a housing, b. a probe reciprocable in said housing and with respect to said member, c. retraction means associated with said probe and operable to retract said probe to an initial starting position, d. biasing means connected to said probe for moving said probe from said initial starting position to a measuring position, into engagement with said member, e. a first signal means associated with said probe and operable to produce a first output signal when said probe is in said measuring position, c. indicating means connected to said sensing assemblies and adapted to receive said first output signals from said sensing assemblies and to indicate said dimension, and d. said frame being pivotable, and having rotary drive means connected to said frame, and rotary control means connected to said rotary drive means for pivoting said apparatus into position for measuring said member.
Claim 2
Dependent Claim
184 words
Apparatus for determining a dimension of a member, said apparatus having: a. a frame, b. a sensing means on said frame adjacent said member and having opposed sensing assemblies aligned with said dimension, 1. each of said sensing assemblies having: a. a housing, b. a probe reciprocable in said housing and with respect to said member, c. retraction means associated with said probe and operable to retract said probe to an initial starting position, d. biasing means connected to said probe for moving said probe from said initial starting position to a measuring position, into engagement with said member, e. a first signal means associated with said probe and operable to produce a first output signal when said probe is in said measuring position, c. indicating means connected to said sensing assemblies and adapted to receive said first output signals from said sensing assemblies and to indicate said dimension, and d. said frame being pivotable, and having rotary drive means connected to said frame, and rotary control means connected to said rotary drive means for pivoting said apparatus into position for measuring said member.
Claim 3
Dependent Claim
60 words
The apparatus recited in claim 1 wherein said control means has a transmitter means, calibration means connected to said transmitter means for positioning said transmitter means and receiver means connected to said transmitter means for receiving a transmitted signal from said transmitter means and connected to said rotary drive means for causing said rotary drive means to pivot said frame.
Claim 4
Dependent Claim
16 words
