Abstract
Adjustable, handheld, woodworking squaring jig that is stable, versatile, and easily maneuvered for the rapid and precise squaring of jointed cuts of varying size across various workpieces which can be used in various work environments, the jig being freely adapted to move across an axis of motion as to accommodate mortise and hinge plate notch cuts of varying sizes, the jig also having a plurality of clamping surfaces which allow it to be conveniently secured to a variety of workpieces and surfaces in different positions, as well as a plurality of slots which allow for the attachment of index clamps, screws or bolts to firmly attach the jig to itself and the mortise or notch cut to be squared.
Claims19
A squaring jig for use in woodworking, comprising:
- a generally L-shaped first jig portion comprising a generally rectangular lateral member and a generally rectangular upper transverse member, the lateral member and the upper transverse member being interconnected at a 90-degree angle, the lateral member having an inner surface, an outer surface, and an end surface, the upper transverse member having an upper surface, a lower surface, an inner surface, and an outer surface, wherein the upper transverse member defines a slot normal to and extending through the upper surface and the lower surface, wherein the upper transverse member defines one of a guide tongue protrusion and a groove;
- a generally L-shaped second jig portion comprising a generally rectangular lateral member and a generally rectangular lower transverse member, the lateral member and the lower transverse member being interconnected at a 90-degree angle, the lateral member having an inner surface, an outer surface, and an end surface, the lower transverse member having an upper surface, a lower surface, an inner surface, and an outer surface, wherein the lower transverse member defines a slot normal to and extending through the upper surface and the lower surface, wherein the lower transverse member defines another of one of a guide tongue protrusion and a groove adapted for moveable mating with the generally L-shaped first jig portion;
- a securing member to secure the first jig portion and the second jig portion together when the guide tongue protrusion is at least partially within the groove and the slots are at least partially aligned along their longitudinal length;
- and
- further comprising at least one clamping portion adapted for being clamped to at least one of a table, a workpiece, and another fixture by a woodworking clamp and extending outwardly from one of the lower transverse member, the upper transverse member, the lateral member of the first jig portion, and the lateral member of the second jig portion.

- wherein the lower surface of the upper transverse member comprises one of a guide tongue protrusion and a groove, and wherein the upper surface of the lower transverse member comprises another of one of a guide tongue protrusion and a groove adapted for at least partially receiving and mating in a slidable relationship when the slots are at least partially aligned;
- one of a releasable index clamp, screw and bolt comprising a shaft having first and second ends, one of a handle, a knob, a socket and a head connected at the first end of the shaft, and a key connected at the second end of the shaft, the shaft adapted for passing through each the slot of the upper transverse member and the slot of the lower transverse member when at least a portion of the guide tongue is located within the groove and when at least a portion of the slots are aligned;
- and
- further comprising at least one clamping portion adapted for being clamped to a table surface by a woodworking clamp and extending outwardly from one of the lower transverse member, the upper transverse member, the lateral member of the first jig portion, and the lateral member of the second jig portion.
