Abstract: A method for bonding a tubular shaft to an end fitting to produce an assembly wherein the shaft and the end fitting are in axial alignment and which is capable of transmitting high torque, said method employing an end fitting provided with a mating section having two concentric cylindrical walls which describe an annular cavity or socket adapted to receive the tubular shaft therein. The high torque carrying capacity of the joint produced in accordance with the invention results from the fact that the shaft is bonded to the mating section of the end fitting on both its interior and exterior surfaces and is in axial alignment with the end fitting. Such axial alignment results from the presence of a resilient sealing ring and an annular shoulder, positioned near the top and base of the inner cylindrical wall of the mating section, which contact the inner surface of the tubular shaft and center the shaft around said wall when the shaft is inserted into the bonding socket of the end fitting.

Abstract: A wooden truss structure comprises upper and lower chords, each of which is grooved on the side facing the opposite chord. A web member formed of sheet material, such as plywood, interconnects the chords and fits within the chord grooves. At the web/groove interface, the webs are scalloped to provide alternating alignment guide areas and glue vent areas which extend above the interface and allow the escape of excess glue from the groove. The scalloping, in addition to venting the glue line, forms individual, pressurized glue pockets which assure even glue distribution. The scalloping is preferably provided by pressing the wood web material to compress it at the glue vent areas and thus permit the web member, due to its memory, to expand after contact with the glue. This expansion pressurizes the glue pockets and forces glue from the joint area into the wood further enhancing the expansion process. The web is rigidly bonded to the chord members, all while being aligned by the alignment guide portion.

Abstract: A method of rigidly fixing an end portion of an elongated column member within a cavity in a body member. A quantity of hardenable adhesive material is placed into the cavity such that when the column member end portion is inserted into the cavity, the resulting displacement of a portion of the adhesive material causes the adhesive material substantially exactly to fill the cavity. The column member end portion is then inserted into the cavity, and the adhesive material is allowed to harden. The angular position of the column member relative to the body member can be adjusted as desired prior to hardening of the adhesive material. Preferably, the method is automated, including injecting a measured amount of adhesive material into the cavity and holding the column member and the body member in a jig while the adhesive material hardens. The adhesive material can be an epoxy resin, and if desired, the hardening can be accomplished by heat curing.

Abstract: A method for bonding a tubular shaft to an end fitting to produce an assembly wherein the shaft and the end fitting are in axial alignment and which is capable of transmitting high torque, said method employing an end fitting provided with a mating section having two concentric cylindrical walls which describe an annular cavity or socket adapted to receive the tubular shaft therein. The high torque carrying capacity of the joint produced in accordance with the invention results from the fact that the shaft is bonded to the mating section of the end fitting on both its interior and exterior surfaces and is in axial alignment with the end fitting. Such axial alignment results from the presence of a resilient sealing ring and an annular shoulder, positioned near the top and base of the inner cylindrical wall of the mating section, which contact the inner surface of the tubular shaft and center the shaft around said wall when the shaft is inserted into the bonding socket of the end fitting.
