Abstract
Abstract A haunch connector for use in building trusses comprises two channels secured together at an angle and clamping means for clamping elements of the truss into the channels. The construction permits the assembly of large trusses without the need for pre-drilling old holes in the ends of the trusses, thus strengthening the points of connection of the structural elements and permitting limited adjustment of the angles of adjacent elements within desired limits.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
251 words
A connector for rigidly joining two adjacent structural elements in a truss, with each structural element being constituted by an assembly of face to face wooden elements providing a beam comprising: a pair of channel members joined together at an angle so that one of said beams can be positioned with the side edges of said wooden elements confined within the channel of each channel member, the channel of said channel members forming three sides of a rectangle to receive said side edges and having outwardly extending elements with bolt-receiving holes; brace means connected to the channel members for maintaining said angle; clamping means of channel shape in which the channel forms three sides of a rectangle for clamping the ends of said two adjacent structural elements securely into the channels of said channel members with the other side edge of at least one of said wooden elements confined within the channel of said clamping means, said clamping means having outwardly extending elements with bolt-receiving holes; and bolt means for compressing said clamping means toward said channel members, said clamping means comprising axially spaced apart clamping strips, each strip located opposite a pair of holes in the outwardly extending elements of said channel members to receive said bolts in aligned holes in said strips and said channel members, whereby tightening of the bolts compresses the strips against a structural element to clamp the side edges of said wooden elements in the channels of said channel members and oppositely disposed clamping strips.
Claim 2
Dependent Claim
251 words
A connector for rigidly joining two adjacent structural elements in a truss, with each structural element being constituted by an assembly of face to face wooden elements providing a beam comprising: a pair of channel members joined together at an angle so that one of said beams can be positioned with the side edges of said wooden elements confined within the channel of each channel member, the channel of said channel members forming three sides of a rectangle to receive said side edges and having outwardly extending elements with bolt-receiving holes; brace means connected to the channel members for maintaining said angle; clamping means of channel shape in which the channel forms three sides of a rectangle for clamping the ends of said two adjacent structural elements securely into the channels of said channel members with the other side edge of at least one of said wooden elements confined within the channel of said clamping means, said clamping means having outwardly extending elements with bolt-receiving holes; and bolt means for compressing said clamping means toward said channel members, said clamping means comprising axially spaced apart clamping strips, each strip located opposite a pair of holes in the outwardly extending elements of said channel members to receive said bolts in aligned holes in said strips and said channel members, whereby tightening of the bolts compresses the strips against a structural element to clamp the side edges of said wooden elements in the channels of said channel members and oppositely disposed clamping strips.
Claim 3
Dependent Claim
235 words
In combination, a connector rigidly joining two adjacent structural elements in a truss, each structural element being constituted by an assembly of face to face wooden elements providing a beam comprising: a pair of channel members joined together at an angle with one of said beams being positioned with the side edges of said wooden elements confined within the channel of each channel member, said channel members having outwardly extending elements with bolt-receiving holes; brace means connected to the channel members for maintaining said angle; clamping means of channel shape clamping the ends of said two adjacent structural elements securely into the channels of said channel members with the other side edges of at least one of said wooden elements confined within the channel of said clamping means, said clamping means having outwardly extending elements with bolt-receiving holes; and bolt means extending through the holes of said clamping means and said channel members for compressing said clamping means toward said channel members, said clamping means comprising axially spaced apart clamping strips, each strip located opposite a pair of holes in the outwardly extending elements of said channel members to receive said bolts in aligned holes in said strips and said channel members, whereby tightening of the bolts compresses the strips against a structural element to clamp the side edges of said wooden elements in the channels of said channel members and oppositely disposed clamping strips.
Claim 4
Dependent Claim
235 words
In combination, a connector rigidly joining two adjacent structural elements in a truss, each structural element being constituted by an assembly of face to face wooden elements providing a beam comprising: a pair of channel members joined together at an angle with one of said beams being positioned with the side edges of said wooden elements confined within the channel of each channel member, said channel members having outwardly extending elements with bolt-receiving holes; brace means connected to the channel members for maintaining said angle; clamping means of channel shape clamping the ends of said two adjacent structural elements securely into the channels of said channel members with the other side edges of at least one of said wooden elements confined within the channel of said clamping means, said clamping means having outwardly extending elements with bolt-receiving holes; and bolt means extending through the holes of said clamping means and said channel members for compressing said clamping means toward said channel members, said clamping means comprising axially spaced apart clamping strips, each strip located opposite a pair of holes in the outwardly extending elements of said channel members to receive said bolts in aligned holes in said strips and said channel members, whereby tightening of the bolts compresses the strips against a structural element to clamp the side edges of said wooden elements in the channels of said channel members and oppositely disposed clamping strips.
Claim 5
Dependent Claim
36 words
A connector combination as defined in claim 2 in which there are three face to face wooden boards in said beam, said boards being arranged with the central board being wider than the two outermost boards.
