Abstract: An attachment for a cable-actuated weight lifting system, the attachment having inner and outer sections capable of pivot relative to each other through the use of bearings or a layer of polytetrafluoroethylene, such pivot allowing for supination and pronation of the hand of a user through a handle connected to the inner section.

Abstract: A pipe hanger assembly for suspension from an associated spacing member extending from a support structure. The hanger assembly includes a generally continuous loop member configured to receive an associated pipe therein. Extending legs on the loop member each include first and second arcuate portions defining interlocking means. The interlocking means are designed to engage an opposed leg and receive an interconnecting member therethrough. The interconnecting member operatively engages the spacing member and has a radially extending flange defining a shoulder for abutting engagement with the loop member.

Abstract: A channel nut for space framing systems characterized by having a pair of outwardly and downwardly extending arms which form a channel, a machine nut which is securely fastened thereto, and a resilient spring projecting upwardly from the machine nut. Such channel nuts are used to thread bolts into space framing members to secure lighting fixtures and the like into ceilings particularly for commercial utilization in plants and other buildings. The channel framing may be extended horizontally or vertically, and the channel nut must have some ability to withstand lateral thrusts so that it grips firmly into slots of the channel framing.The channel nuts of this invention include ordinary machine nuts of the square, hexagonal or elongated rectangular type, which are projection welded to the saddle to strengthen it.

Abstract: A steel closure ring assembly for a barrel or drum of the split ring type that is adapted to close the chime of a barrel and its cover. A pair of metal fittings, one on each end of the ring, tighten the ring and swage it around the barrel to make a tight, liquid-proof seal even under drop test conditions.Each metal fitting incorporates a machine nut with a folded metal housing enclosing its exterior sides while leaving the interior or threaded sides accessible. The nut may have four or six sides with an arcuate member extending from one side in an outward direction or in a direction away from the encapsulated nut, which is adapted to closely conform to the curved metal ring and thereby extend over the chime of the barrel.A tang extends from the sheet metal housing to the side of the fittng away from the end of the split ring and also over the chime and is attached by means of welding.
