Abstract

A framing jig for fabricating subassemblies for use in the construction of buildings. The jig has a supporting base defining a horizontal work surface, an end alignment stop defining a vertical transverse plane, a plurality of stanchions defining a vertical longitudinal plane, and a plurality of levers carried by the stanchions. Two or more parallel wooden members to be fabricated into a header or other subassembly are positioned in abutment with the end alignment stop and adjacent the stanchions. Each lever includes a flat portion movable from a resting position above the members to a clamping position in engagement with the edges of the members. The members can be nailed together when clamped by the lever. A bias spring associated with each lever urges the lever toward its resting position.

Dependent claims

a supporting base having an elongated work surface defining the lower horizontal plane and adapted to support the first plurality of members adjacent a first long side of the base and the second plurality of members adjacent a second long side of the base;
end alignment stop means affixed to the base, defining the vertical transverse plane, adapted to engage an extremity of each of the first plurality of members and thereby locate the same in fixed relationship to the vertical transverse verse plane, and adapted to engage an extremity of each of the second plurality of members and thereby locate the same in fixed relationship to the vertical transverse plane;
a plurality of longitudinal lever stanchions affixed to the base, defining the vertical longitudinal plane perpendicular to the vertical transverse plane and generally parallel with and generally centered between the first and second long sides of the base, a first side of the stanchions adapted to engage a side of one of the first plurality of members and thereby locate the sides of said members parallel to the vertical longitudinal plane and adjacent the first long side of the base, and an opposing second side of the stanchions adapted to engage a side of one of the second plurality of members and thereby locate the sides of said members parallel to the vertical longitudinal plane and adjacent the second long side of the base;
a first plurality of levers, each lever pivotally attached to a different stanchion on the first side thereof and including a flat clamping surface, each such surface having a clamping position above and parallel to the lower horizontal plane and defining the first upper horizontal plane, the clamping surface further having a resting position above the first upper horizontal plane, the clamping surface adapted when in the clamping position to releasably engage an upper edge of each of the first plurality of members and thereby locate said upper edges in the first upper horizontal plane;
and
a second plurality of levers, each lever pivotally attached to a different stanchion on the second side thereof and including a flat clamping surface, each such surface having a clamping position above and parallel to the lower horizontal plane and defining the second upper horizontal plane, the clamping surface further having a resting position above the second upper horizontal plane, the clamping surface adapted when in the clamping position to releasably engage an upper edge of each of the second plurality of members and thereby locate said upper edges in the second upper horizontal plane.
