Abstract: Fasteners, such as bolts, are normally utilized to provide an arrangement to secure two members together. When working forces are applied to the assembled members trying to tear them apart, the size of the bolts and the ability to apply the proper torque to the bolts on the job site become limitations. In the subject arrangement, a fastener assembly is provided having a hollow cylindrical pin with an enlarged portion at one end and a plurality of ridges and grooves at the other end. A hollow cylindrical shear ring, having a chevron shaped cross-section taken along its longitudinal axis, is placed, during assembly, in intimate contact with the plurality of ridges and grooves. A hollow cylindrical compression ring is placed, during assembly, in contact with the hollow cylindrical shear ring.

Abstract: A fastener with components locked to a fastener shank by tapered inserts disposed about a tapered segment of the shank. The attached components include an internal frusto-conical wall having a taper corresponding to the tapered inserts. Both the head as well as the threads of a fastener may be affixed to a common shaft.

Abstract: A metallic threaded composite fastener, particularly suited for high temperature applications, has a body member made of high temperature-resistant composite material with a ceramic coating. The body member has a head portion configured to be installed in a countersunk hole and a shank portion which is non-circular and tapered. One part of the shank may be non-circular and the other part tapered, or the two types of surfaces could be combined into a frustum of a non-circular cone. A split collar member made of high strength, high temperature-tolerant metal alloy is split into two halves and the interior of the halves are configured to engage the shank. The exterior of the collar has external threads and the upper portion of the collar has a circumferential groove which receives a lock ring to secure the collar halves to the shank.

Abstract: The threaded split-bushing fastener assembly has been designed for high temperature applications such as on hypersonic vehicles. The fastener assembly consists of a pin (with a standard countersunk head at one end and a tapered end at the other end), a tubular threaded split-bushing, a nut, and a washer. Installation is accomplished by inserting the pin in the parts to be fastened, then slipping the washer and split-bushing on the tapered end of the pin and finally screwing the nut onto the split-bushing. Tightening of the nut allows preloading of the fastener assembly.

Abstract: The tapered split-bushing fastener has been designed for high temperature applications. The fastener consists of a pin (with a standard countersunk head at one end and a tapered end at the other end), a split tapered bushing, a washer and a sleeve with an internal taper. Installation is accomplished by inserting the pin in the parts to be fastened, then slipping the washer and the split bushing on the tapered end and finally pushing the sleeve onto the split bushing. Pushing the sleeve causes the split-bushing to react against the washer and generate the fastener axial preload. A high temperature adhesive is then injected to lock the fastener in place.

Abstract: A wedge and bolt assembly serves to temporarily connect two prefabricated panel units for use in assembling a concrete wall form. A bolt support member is mountable on a prefabricated panel, and includes a first hollow passage formed therethrough to slidingly receive a bolt. The bolt has a main body portion with two recesses formed therein to receive an engaging member. The bolt also has a projecting end with a transverse slot formed therethrough for receiving a wedge after insertion through extending flanges of aligned panel units. The bolt support member includes a second hollow passage formed therein transverse to the first hollow passage in which an engaging member is disposed, the engaging member being biased into the recesses of the bolt by a coil spring or the like. A set screw or the like is inserted in the second passageway of the bolt support member to retain the spring and engaging member therewithin.

Abstract: A device for temporarily coupling together and subsequently separating a first member and a second member, comprises:a male member joined to the first member;a female member joined to the second member and comprising an axially elongate hollow body in which are disposed a retaining sleeve adapted to retract radially onto the male member or to expand, a piston sliding axially to retract/expand the retaining sleeve and, in the piston, disposed along the axis, an ejector finger joined to the piston by a readily broken member, andselective control means for the piston adapted to command movement of the piston and optionally simultaneous breaking of the readily broken member and to cause the ejector finger to slide axially, the finger projecting axially relative to the piston.

Abstract: A shift lever assembly for an automotive transmission including a lower shift lever for engaging and operating an automotive transmission to select a desired gear stage. An upper shift lever is detachably coupled to the lower lever and serves for manual actuation to effect movement of the lower shift lever. One of the upper and lower shift levers terminates at one end in a shaft. The other of the upper and lower shift levers terminates at one end in a bore into which is received the shaft. The coupling is effected by a fastener that cams and secures the shaft in the bore. The coupling may be easily detached.

Abstract: A pin and wedge combination for connecting together adjoining lattice bridge panels (M) is characterised in that the pin (P) has a plurality of diametric slots (S) spaced along its axis and with ends which overlap in the general direction of the axis. Additionally, the wedge (W) is curved and resiliently deformable in a plane perpendicular to its depth whereby the wedge is insertable by deformation into any selected one of the slots (S) and thereafter resiliently engages spaced points of the sides of that slot so as to be self-retaining therein.

Abstract: A tapered pin-key for securing a part and a shaft where the part has a cylindrical bore for receiving the shaft and a keyway tangentially intersecting the bore, and the shaft has a tangential groove shallower than the depth of the intersection of the keyway and the bore. The pin-key comprises two cylindrical surfaces converging at a small angle. The radius of the two cylindrical surfaces, the keyway, and the groove in the shaft, are all equal. The pin-key is placed in the keyway with one face engaging the surface of the keyway and the second face engaging the surface of the groove in the shaft, thereby securing the part and the shaft against relative rotational or axial movement.

Abstract: A carriage for suspending a load such as a compartment of a vehicle or the like, is basically comprised of a pin, rod or bar from which the load is centrally suspended and which by and in itself is suspended by two wheel carriers, each supporting a wheel for running on opposite flanges of a rail; each wheel carrier has a clamping bore intersecting the bore receiving the load carrying rod and a tension pin-with-wedge is inserted in an intersecting bore for clampingly engaging the load bearing rod upon tightening of a nut on an external thread of the respective tension pin; loosening of the nuts releases a contour fitting engagement and permits the wheel carrier to be adjusted into any desired position on the load carrying rod; the wedges may be constructed as cutting edges for cutting into the load carrying rod upon tightening.

Abstract: An electrical wiring box having a pair of mounting elements associated therewith for permitting the quick and easy mounting of an electrical device within the wiring box. Each mounting element has a central portion with a screw receiving opening. Side portions extend from the central portion and deflective V-shaped flanges including thread-engaging portions are integral with the side portions. The thread-engaging portions terminate at opposed thread-engaging surfaces which are parallel and lie at an acute angle to a reference line which is perpendicular to the major axis of the flanges. The mounting elements fit in openings in the box and are held in place by abutments on the central portions and by the V-shaped flanges. In installing an electrical device in the box, screws are pushed through the central openings and into the regions between the thread-engaging surfaces. The screws may be further tightened by turning a fraction of a turn.

Abstract: The invention concerns an anchoring device, more particularly a screw anchoring device, for insertion in an opening, e.g. in the end of a tube, to there form an anchor for a screw or bolt introduced into the opening. The device comprises an internally threaded locking body, preferably a conventional hexagonal nut, and a sleeve which is shaped, at least at one end thereof, to provide a tip portion, e.g. by being cut off obliquely. The device is inserted into the opening with the screw engaging the locking body and loosely accommodating the sleeve, whose tip portion is facing the body. In tightening the screw the locking body becomes wedged between the tip portion of the sleeve and an opposing portion of the wall of the opening. The union body-sleeve will then form a solidly fixed anchor for the screw, which itself can be loosened and tightened as desired.
