Combined miter box, corner clamp and measuring gauge

Claim 1

A combined miter box, corner clamp and measuring gauge device for producing rectangular frames from trim strips, comprising a. an integral support having two outwardly extending arms diverging perpendicularly from each other and an integral supporting ledge extending therebetween, b. straight vertically upstanding shoulders at the junctions of the inner ends of said arms and ledge, said shoulders extending in planes perpendicular to each other with a gap at their adjacent ends for accommodating a cutting saw blade therebetween, c. internally threaded lugs at the outer ends of said arms, each provided with a threaded adjusting screw with operating means therefor at the outer end and a clamping jaw at the inner end for cooperative action with a respective shoulder to clamp a trim strip therebetween, d. said integral ledge having a channel in the top thereof along a line bisecting the right angle between the longitudinal axes of said arms and below said gap for allowing movement of said cutting saw blade below the upper surfaces of said arms incidental to the angular cutting of the trim strips adapted to rest on said arms, e. a unitary saw guide assembly and support means therefor on said ledge at one side of said channel for detachably setting the cutting saw blade in overlying relation to said channel and gap, and f. a rectilinear measuring gauge detachably connected to an outer edge of one of said arms for measuring the length of the trim strip from the vertical plane containing said bisecting line.
