Abstract
Abstract An in-process measuring gage for use in connection with turning machines and the like wherein the gage is self-contained and adjusting for producing a precision output signal indicative of workpiece size. The gage has a column and a pair of arms attached to slides with the arms being normally biased and gravity actuated toward each other for maintaining continuous contact with a workpiece regardless of whether or not the workpiece is round. The arms while fixedly held in an outwardly projecting position include means for swinging transversely to an out of the way position in the event the arms encounter excessive resistance or an obstruction. The arms may be set in a predetermined position with clamping means and an arrangement is provided for permitting a certain amount of float by the arms so that they may move longitudinally to prevent damage should the arms be brought into contact with an oversized workpiece when they are clamped in the fixed position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
194 words
An in-process measuring gage for use with a turning machine or the like, comprising in combination, a base, a column extending outwardly from said base, a pair of arms slidably carried by said column, said arms having ends projecting outwardly substantially perpendicular to the column, contact means at the outer ends of each of said arms for engaging a rotating workpiece between said arms, means for normally biasing said arm means toward one another for maintaining continuous engagement with a workpiece disposed between said arms by said contact means, signal generating means connected to said arms for producing an output indicative of the relative spaced apart position of said arms and any changes in relative spaced apart position of said arms, each of said arms including a clamp member and means fixed with respect to said column for engagement by said clamp members so that said arms may be set in predetermined positions spaced apart from one another, and said fixed means includes means for imparting a limited amount of float so that when said arms are clamped to said fixing means the arms are free to move by said limited amount of float.
Claim 2
Dependent Claim
194 words
An in-process measuring gage for use with a turning machine or the like, comprising in combination, a base, a column extending outwardly from said base, a pair of arms slidably carried by said column, said arms having ends projecting outwardly substantially perpendicular to the column, contact means at the outer ends of each of said arms for engaging a rotating workpiece between said arms, means for normally biasing said arm means toward one another for maintaining continuous engagement with a workpiece disposed between said arms by said contact means, signal generating means connected to said arms for producing an output indicative of the relative spaced apart position of said arms and any changes in relative spaced apart position of said arms, each of said arms including a clamp member and means fixed with respect to said column for engagement by said clamp members so that said arms may be set in predetermined positions spaced apart from one another, and said fixed means includes means for imparting a limited amount of float so that when said arms are clamped to said fixing means the arms are free to move by said limited amount of float.
Claim 3
Dependent Claim
56 words
A gage as claimed in claim 1 wherein each of said arms includes a slide disposed about said column and an arm member hingedly supported by said slide so that said arms may swing transversely with respect to said slides and shear means fixedly holding said arms in outwardly projecting positions normally preventing such transverse swinging.
Claim 4
Dependent Claim
34 words
A gage as claimed in claim 1 wherein said biasing means comprises freely suspended counterweights connected to respective ones of said arms by cables so that said arms are gravity actuated toward one another.
Claim 5
Dependent Claim
41 words
A gage as claimed in claim 1 including mounting means for adjustably mounting said base to said machine, said mounting means having a longitudinally extending sliding connection with said base and means for shifting said base longitudinally along said mounting means.
Claim 6
Dependent Claim
38 words
A gage as claimed in claim 4 wherein said mounting means includes a pair of stops disposed at opposite ends thereof for limiting the forward and rearward end movement of the base with respect to said mounting means.
Claim 7
Dependent Claim
23 words
A gage as claimed in claim 1 wherein said contact means at the outer ends of each of said arms comprises a roller.
