Abstract
A set of gauges assembled into a single unit, each guage consisting of a flat tongue with a specific sized rounded corner and a 45 degree angle offset along one side edge thereof, each gauge having a different size offset steps, and all the tongues pivoting from a common shaft in a frame.
Claims3
A 45 degree chamfer and radius gauge set, comprising in combination, a plurality of flat templates;
- and a U-shaped frame having fastener means across one of the ends thereof for fastening said templates thereto, said plurality of templates being pivotally mounted by said fastening means;
- each of said templates comprising a flat structure of rectangular cross-section with a first longitudinal side surface, a second longitudinal side surface, a first rounded transverse end surface at one end of the longtitudinal surfaces, and a second transverse end surface at the other end of said longitudinal side surfaces;
- said second longitudinal side surface having a first surface portion and a second surface portion offset from said first surface portion by a 45 degree angle offset, and that portion adjoining both said first longitudinal side surface and said second transverse end surface being rounded to a specific dimension to define a radious gauge, whereby said offset surface may measure a chamfered surface of a work piece and said rounded portion may measure a rounded surface of a work piece.
