Patent number: 4291996Abstract: A positive nail-angling device for metal connectors for prevention of splitting due to beam "hanging" caused by side nailing and wood shrinkage and prevention of splitting of laminated members such as plywood, glued laminated timbers (glulam) and prefabricated wood joists (microlams). The device includes a slot-like opening formed in the face of a metal connector and a tab-like member formed from the displaced face material from the slot-like opening and bent along a bend line which constitutes one end of the slot-like opening. The slot-like opening and tab-like member in the connector confine the nail so that it can only penetrate the wood member at a pre-selected angle. In many applications, the tab-like member is bent at an angle of 45.degree. to the face of the metal connector.Type: GrantFiled: July 1, 1980Date of Patent: September 29, 1981Assignee: Simpson Manufacturing Co., Inc.Inventor: Tyrell T. Gilb

Patent number: 4261155Abstract: An infinite skewed and sloped sheet metal hanger for holding a supported structure to a supporting structure. The hanger consists of a supporting member which is connected to the supporting structure, a pin and a supported gusset-like member. Load shear is carried to the face support; not through the pivot connecting pin. This is accomplished by closely holding tab members with the supported gusset-like member.Type: GrantFiled: November 16, 1979Date of Patent: April 14, 1981Assignee: Simpson Manufacturing Co., Inc.Inventor: Tyrell T. Gilb

Patent number: 4230416Abstract: A metal connector for joining wood members which intersect at an angle less than 90 degrees formed with restricted slot nail openings so that the metal connector can be easily joined to the wood members by inserting the nail fastener into the nail opening at an angle other than a 90 degree angle. The opening has a width slightly larger than the diameter of the nail fastener and a length substantially greater than the diameter of the nail fastener. The nail is inserted into the opening at a selected angle so that the diagonally opposed outer edges of the sides of the opening tangentially register with the opposed sides of the fastener. When the nail is inserted there is little or no relative movement between the nail fastener and the connector.A method for forming a skewed connector formed with the restricted slotted nail fastener openings.Type: GrantFiled: October 15, 1979Date of Patent: October 28, 1980Assignee: Simpson Manufacturing Co., Inc.Inventor: Tyrell T. Gilb

Patent number: 4069635Abstract: A truss structure having upper and lower wood chords joined by tubular metal web members. The chords are formed with a plurality of slots for receiving the ends of the web members. Each slot extends from the inner face to the outer face of the chord. Cross bores extend from the inner walls of the slots laterally toward the edges of the chords. Clevis assemblies are inserted into each slot. The ends of the web members are inserted into the slots and attached to the clevis members by metal pins. Load forces from the webs are distributed to the faces of the wood chords through flanges on the clevis member or connector plates. Load forces are also distributed to the wood chords through the clevis member to the pin and directly to the wood by the configuration of the clevis member.Type: GrantFiled: January 10, 1977Date of Patent: January 24, 1978Assignee: Simpson Manufacturing Co., Inc.Inventor: Tyrell T.
