Abstract

Abstract A height gage is disclosed including a vertical column of circular cross section with a carriage that rides up and down the column. The carriage is maintained in fixed radial position relative to the column by a longitudinal groove in the column into which a longitudinal surface is formed that extends accurately on a radius of the column throughout the length of the column. A shoe which is mounted on the carriage engages this vertical surface and maintains the carriage always in proper alignment. Means are also provided on the column and the carriage to measure the position of the carriage on the column.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 94 words
A height gage comprising a base, a vertical circular column mounted on said base, a carriage movable on said column, said column having a longitudinal groove therein with at least one surface extending on a chord of said column, a second surface on a radius of said column in said groove, shoe means on said carriage engaging the second surface, resilient means on said shoe engaging said one surface of said groove, means coupled between said column and said carriage for generating an electrical signal as a function of distance and displaying the information.
Claim 2
Dependent Claim 94 words
A height gage comprising a base, a vertical circular column mounted on said base, a carriage movable on said column, said column having a longitudinal groove therein with at least one surface extending on a chord of said column, a second surface on a radius of said column in said groove, shoe means on said carriage engaging the second surface, resilient means on said shoe engaging said one surface of said groove, means coupled between said column and said carriage for generating an electrical signal as a function of distance and displaying the information.
Claim 3
Dependent Claim 22 words
A height gage as in claim 1 wherein said second surface is formed by a longitudinal guiding member mounted in said groove.
Claim 4
Dependent Claim 19 words
A height gage as in claim 1 wherein guiding means are mounted on said carriage and embrace said column.
Claim 5
Dependent Claim 19 words
