Portable height and depth setting gauge

Claim 2

A gauge for measuring displacement comprising a base which forms a reference surface having substantially vertical side surfaces and an inclined surface said inclined surface having an inclination with respect to said reference surface, a gauge head seated upon said surface for sliding adjustments there along, a first contact surface integral with said head extending laterally beyond one of said vertical side surfaces of said base and substantially parallel to said reference surface and adapted to touch surfaces for measurement, a scale on said inclined surface, and an indicating finger on said gauge head adapted to indicate directly on said scale the displacement of said contact surface with respect to said reference surface continuously as said gauge head is slidably moved along said inclined surface.

Claim 3

The invention recited in claim 1 further including a second contact surface integral with said head being substantially parallel to said reference surface and extending laterally beyond said base opposite said first contact surface and vertically displaced therefrom, and said finger concurrently indicates the respective displacements of said first and second contact surfaces as said gauge head is slidably moved along said inclined surface.

Claim 4

The invention recited in claim 1 further including calibrating means for repositioning said finger with respect to said head so as to alter the indicated displacement of said first contact surface with respect to said reference surface within a prescribed range less than the total scale range of said direct reading scale.

Claim 5

The invention recited in claim 1 wherein said inclined surface includes a guide surface protruding laterally with respect to one of said side surfaces, said guide surface having an upper and lower surface and further including a locking arrangement comprising a lever secured via a common shaft to an eccentric cam, said lever and cam being mounted on said gauge head and positioned so as to contact said guide surface by turning said lever and shaft to make a frictional contact between said cam and said undersurface of said guide surface.

Claim 6

The invention set forth in claim 1 further including means for more precisely locating said contact surface with respect to said reference surface comprising first vernier indicating indicia combined with said finger situated on said gauge head, and correspondingly aligned second vernier indicating indicia on said inclined surface viewable through an aperture in said finger.

Claim 7

A gauge for measuring vertical displacement of a tool surface from a reference surface comprising a base which forms the reference surface, an inclined surface having an inclination with respect to said reference surface and side surfaces contiguous with said base and inclined surface, a gauge head seated upon said inclined surface for sliding adjustments there along, said inclined surface extending beyond said side surfaces and the extended portions thereof forming left and right side protruding guide members, said gauge head having downward and inwardly extending curved fingers in registry with said guide members for restricting movement of said gauge head to sliding movement up and down said inclined surface, said gauge including a contact member extending laterally beyond one of said side surfaces and substantially parallel to said reference surface adapted to come into contact with said tool surfaces to be measured, a height indicating indicia on said inclined surface, an indicating finger adjustably affixed to said gauge head and situated so as to continuously indicate vertical displacement of said contact member with respect to said reference surface as said gauge head and contact member are slidably moved along said inclined surface, and means for adjusting said finger with respect to said indicating indicia so as to directly indicate the displacement of said contact member with respect to said reference surface.

Claim 8

A gauge for measuring vertical displacement of a tool surface from a reference surface comprising a base which forms the reference surface, an inclined surface having an inclination with respect to said reference surface and side surfaces contiguous with said base and inclined surface, a gauge head seated upon said inclined surface for sliding adjustments there along, said inclined surface extending beyond said side surfaces and the extended portions thereof forming left and right side protruding guide members, said gauge head having downward and inwardly extending curved fingers in registry with said guide members for restricting movement of said gauge head to sliding movement up and down said inclined surface, said gauge including a contact member extending laterally beyond one of said side surfaces and substantially parallel to said reference surface adapted to come into contact with said tool surfaces to be measured, a height indicating indicia on said inclined surface, an indicating finger adjustably affixed to said gauge head and situated so as to continuously indicate vertical displacement of said contact member with respect to said reference surface as said gauge head and contact member are slidably moved along said inclined surface, and means for adjusting said finger with respect to said indicating indicia so as to directly indicate the displacement of said contact member with respect to said reference surface.

Claim 9

The gauge recited in claim 6 further including another contact member extending laterally beyond said base oppositely situated from and vertically displaced from the aforementioned contact member, and a separate scale in said indicating indicia to indicate the vertical displacement of said another contact member from the reference surface, and wherein said finger concurrently indicates the displacement of both contact members from the reference surface as said gauge is slidably moved along said inclined surface.
