Abstract

A caliper includes two legs pivotably connected together at first ends thereof. Second ends of the legs can abut opposite first and second sides of an object to be gauged. Each leg includes first and second faces extending between the first and second ends. A scale is formed on the first surface of each leg. Each leg further includes an inclined surface between the first and second faces. The size of the object is indicated by an intersection of the scales. The inclined surfaces of the legs abut third and fourth faces of the object so that the gauging result is reliable.

A caliper comprising, in combination:

a first leg including first and second ends spaced along a first longitudinal axis, with the first leg further including first and second faces extending between the first and second ends of the first leg, with the first and second faces spaced from each other in a thickness direction perpendicular to the first longitudinal axis, with the first face of the first leg including a first scale intermediate the first and second ends of the first leg along the first longitudinal axis, with the first leg further including a first inclined surface extending between the first and second faces of the first leg in the thickness direction, with the first inclined surface at a first acute angle with the first longitudinal axis, with the first inclined surface intermediate the second end of the first leg and the first scale along the first longitudinal axis;
and
a second leg including first and second ends spaced along a second longitudinal axis perpendicular to the thickness direction, with the first end of the second leg pivotably connected to the first end of the first leg, with the second leg further including first and second faces extending between the first and second ends of the second leg, with the first and second faces of the second leg spaced from each other in the thickness direction, with the first face of the second leg including a second scale intermediate the first and second ends of the second leg along the second longitudinal axis, with the second leg further including a second inclined surface extending between the first and second faces of the second leg, with the second inclined surface at a second acute angle with the second longitudinal axis, with the second inclined surface intermediate the second end of the second leg and the second scale along the second longitudinal axis,
with the second ends of the first and second legs being adapted to abut first and second sides of an object to be gauged by the caliper, with the first and second sides opposite to each other, with the object further including third and fourth sides intermediate the first and second sides, with the first and second inclined surfaces of the first and second legs adapted to abut the third and fourth sides of the object, with a size of the object indicated by an intersection of the first and second scales,
with the second end of each of the first and second legs including a protrusion, with the protrusions of the first and second legs spaced from each other and abutting the first and second sides of the object, with the first leg including a first bend intermediate the second end of the first leg and the first scale along the first longitudinal axis, with the second leg including a second bend intermediate the second end of the second leg and the second scale along the second longitudinal axis, and with the first and second bends being so configured that the protrusions are spaced from and substantially parallel to each other.
