Abstract: A fastener and a workpiece assembly comprises a fastener composed of a relatively strong, inflexible material and having a shank portion. Wings are disposed upon the shank, and the workpiece has portions thereof composed of a relatively flexible, resilient material. An aperture having a predetermined diameter is located within each one of the workpiece portions. The wings define an outer diameter substantially greater than the diameter of each aperture. The wings are capable of swaging the apertures, thereby increasing the diameters thereof, so as to allow for passage of the wings therethrough. The relatively flexible, resilient material has sufficient elastic memory so that the diameter of each aperture will become smaller than the outer diameter defined by means of the wings after being swaged by means of the passage of the wings therethrough.

Abstract: Systems for supporting loads which includes an elongated strut (or channel). A load-supporting component is fixed to the channel at a selected location therealong by a faster threaded into an associated channel nut. The channel nut is easily and quickly installed in the channel through a gap between flanges paralleling and spaced inwardly from the side walls of the channel and then rotated (and displaced along the channel, if necessary) to seat a lug on the nut in cooperating notches formed opposite each other in the flanges of the channel. This interfitting relationship provides a positive connection between the channel nut and the channel, keeping even heavy loads and loads subjected to vibration, hammering, or the like from slipping, even if the supporting channel is vertically oriented and the load is therefore the most susceptible to slippage.

Abstract: A transmission shift yoke (3) (see FIG. 2) has to slide over the shift bar (1) and then be anchored accurately in the desired position by a fastener, i.e., set screw or bolt (8). The set screw must be locked to prevent its loss or more seriously its falling into machinery. A expansible snap ring (10) is arranged on a spotface (11) in a recess (12) in the bar; it is expanded by the tapered shank (14) of the fastener (8) and then snaps into a waist (19) of the fastener to prevent its being readily unscrewed more than half a turn or so. A really robust torque, however, on the head (9) by means of a spanner/wrench will forcibly expand the snap ring out of the waist (19) and over the widest part of the tapered shank (13).

Abstract: A shear joint for torsionally connecting a hub to a yoke for a universal joint includes a shear bolt of a certain length extending through a flange of the hub into a radially disposed T-shaped slot in a flange of the yoke. A nut is inserted into the lateral leg of the T-shaped slot and is tightened onto the bolt by turning the bolt to hold the yoke and hub together axially and torsionally. If a bolt longer than the proper length is used to repair the joint, it abuts the top of the T-shaped slot and prevents holding the yoke and hub together by tightening the bolt, thereby encouraging use of a bolt of the proper size.
