Easily attachable and detachable gauge for re-locating tested bevel gears on a gear-cutting machine

Claim 1

A gauge for re-locating imperfectly cut but salvageable bevel gears removed for testing from a gear-cutting machine having a horizontally disposed rotatable gear-supporting mandrel upwardly covered by a co-axial cylindrically curved ferromagnetic sheet, said gauge comprising: a base member partly of magnetic material having an elongated shallow channel, of inverted V-shape in cross-section, in its bottom surface for magnetically firmly attaching said base member to said ferromagnetic sheet; a pair of spaced upright members fixed to the top of said base member; a cylindrically bored body positioned between said upright members; means pivotally and frictionally holding said bored body in positions rotated about a horizontally disposed axis transverse to the bore of said bored body; a cylindrical arm rotatably and axially adjustably received in the bore of said bored body; a probe member connected to an end of said arm and extending downwardly therefrom and having a rounded-body tip for insertion between adjacent teeth of a gear mounted on said mandrel.
