Abstract
Abstract A linear measuring apparatus comprises support feet for placing on a reference plane. A rod is movable perpendicularly to the plane against the action of a return spring. An extremity of the rod has a sidewardly protruding flange with vertical play equal to its own thickness. The rod has a rack driving a pinion with a pointer which directly indicates a measurement with reference to the plane, taken from either the upper or lower surface of the flange.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
170 words
Apparatus for measuring the overlap of cutters in relation to a reference plane in a woodworking machine, comprising a body, means for supporting said body on a reference plane, a rod slidably mounted in said body for lengthwise movement in a direction perpendicular to a plane defined by said supporting means, a lever extending laterally from said rod for moving said rod in one direction, spring means for moving said rod in the opposite direction, a sidewardly protruding flange slidably mounted on an extremity of said rod extending beyond said plane with play equal to its own thickness in a direction lengthwise of said rod, a rack formed on a portion of said rod inside body, a pinion rotatably mounted in said body in meshing engagement with said rack a pointer fixed, to said pinion and a scale on said body concentric with said pinion and cooperating with said points to indicate a measurement with reference to said plane taken from either the upper or lower surface of said flange.
Claim 2
Dependent Claim
170 words
Apparatus for measuring the overlap of cutters in relation to a reference plane in a woodworking machine, comprising a body, means for supporting said body on a reference plane, a rod slidably mounted in said body for lengthwise movement in a direction perpendicular to a plane defined by said supporting means, a lever extending laterally from said rod for moving said rod in one direction, spring means for moving said rod in the opposite direction, a sidewardly protruding flange slidably mounted on an extremity of said rod extending beyond said plane with play equal to its own thickness in a direction lengthwise of said rod, a rack formed on a portion of said rod inside body, a pinion rotatably mounted in said body in meshing engagement with said rack a pointer fixed, to said pinion and a scale on said body concentric with said pinion and cooperating with said points to indicate a measurement with reference to said plane taken from either the upper or lower surface of said flange.
Claim 3
Dependent Claim
52 words
Apparatus according to claim 1, in which said pinion is fixed on a shaft rotatably supported in said body and in which pointers fixed on opposite ends of said shaft cooperate with scales at opposite faces of said body wherein said measurement is indicated on both of opposite faces of said body.
Claim 4
Dependent Claim
43 words
Apparatus according to claim 1, in which said body is provided with a recess parallel to said rod and in which said lever is fixed to said body and projects laterally therefrom into said recess in which it is accessible for digital operation.
Claim 5
Dependent Claim
24 words
Apparatus according to claim 3, in which said spring means comprises a tension spring acting between said lever and a portion of said body.
Claim 6
Dependent Claim
24 words
Apparatus according to claim 1, further comprising spiral spring means acting between said pinion and said body to apply a torque to said pinions.
Claim 7
Dependent Claim
69 words
Apparatus according to claim 1, in which the side of said body opposite said supporting means is provided with a reference surface parallel to the plane defined by said supporting means, and in which the extremity of said rod opposite that on which said flange is provided is extendable out through an opening in said reference surface by an amount indicated by said points in cooperation with said scale.
