Abstract
Abstract A wood framing hanger including an angle element having a top flange adapted for connection to the top side of a wood structural member and a lower depending flange formed at a substantially right angle. The hanger also includes a stirrup element having a seat and right angularly related side flanges. The stirrup flanges are one half the width of the seat and welded at their upper edges to the depending flange of the angle element. The top flange angle element is formed with nailing tabs at one end and a welding tongue at the other end. The top flange configuration is devised as a nested progressive for high production automated tooling. Likewise the stirrup element is designed for high-production automated tooling and any size may be made from the same single die system using different width coil stock.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
174 words
A purlin hanger comprising: a. an angle element having a top flange adapted for connection to the top side of a wood member and having a lower depending flange formed at substantially a right angle to said top flange; b. a stirrup element adapted for receiving a wood member including a seat and a pair of integral right angularly related side flanges; c. said side flanges include an upper portion having a width equal to one half the depth of said seat and a lower minor portion having a dimension gradually increasing in width until it is equal to the depth of said seat; d. weld means attaching a portion of the back edge of said stirrup element to the front face of the lower depending flange of said angle element; and e. an embossment in the side of each of said side flanges of said stirrup extending substantially the length of said upper portion increasing the effective thickness of said flanges for increasing the resistance of said flanges to torsion and bending forces.
Claim 2
Dependent Claim
174 words
A purlin hanger comprising: a. an angle element having a top flange adapted for connection to the top side of a wood member and having a lower depending flange formed at substantially a right angle to said top flange; b. a stirrup element adapted for receiving a wood member including a seat and a pair of integral right angularly related side flanges; c. said side flanges include an upper portion having a width equal to one half the depth of said seat and a lower minor portion having a dimension gradually increasing in width until it is equal to the depth of said seat; d. weld means attaching a portion of the back edge of said stirrup element to the front face of the lower depending flange of said angle element; and e. an embossment in the side of each of said side flanges of said stirrup extending substantially the length of said upper portion increasing the effective thickness of said flanges for increasing the resistance of said flanges to torsion and bending forces.
Claim 3
Dependent Claim
29 words
A purlin hanger as described in claim 1 comprising: a. the uppermost portions of said upper portions of said side flanges of said stirrup element gradually decrease in width.
Claim 4
Dependent Claim
65 words
A purlin hanger as described in claim 2 comprising: a. said top flange is formed with a pair of spaced tab members extending along the side edges, and said lower depending flange is formed with a centrally located tongue portion extending beyond the side edges of said lower flange, and b. said stirrup element is attached to the tongue portion of said lower depending flange.
Claim 5
Dependent Claim
41 words
A purlin hanger as described in claim 3 comprising: a. a plurality of embossments spaced along the width of said angle element extending partially onto said top flange, around said right angular formed portion and partially onto said lower depending flange.
Claim 6
Dependent Claim
34 words
A purlin hanger as described in claim 3 comprising: a. The width of said tongue portion of said lower depending flange is dimensioned to equal the distance between said tabs on said top flange.
Claim 7
Dependent Claim
138 words
An improved purlin hanger comprising: a. an angle element having a top flange adapted for connection to the top side of a wood member and having a lower depending flange formed at substantially a right angle to said top flange; b. said top flange is formed with a pair of spaced tab members extending along the side edges, and said lower depending flange is formed with a centrally located tongue portion extending beyond the side edges of said lower flange; c. a stirrup element adapted for receiving a wood member including a seat and a pair of integral right angularly related side flanges; d. weld means attaching the back edge of said stirrup element to the front face of the tongue portion of said lower depending flange; and e. said tab members are formed with fastener receiving openings.
Claim 8
Dependent Claim
