Abstract: A lock nut having a locking ring with a spoon-shaped lug. The lock ring includes a nut body having a bore with an interior threaded portion and a substantially cylindrical recess coaxial with the threaded portion of the bore. The recess includes a single notch on a portion of the recess. In addition, the lock ring includes a threaded locking ring positioned within the recess. The locking ring is deformed when threading the bolt onto the lock nut to frictionally grip the bolt. The locking ring also includes a single projecting lug at one side only of the locking ring, which fits into the notch to prevent relative rotation between the ring and the nut body. The lug includes a bowl-shaped nodule for collecting shavings gathering within the threads of the bolt and the interior bore of the lock nut.

Abstract: A method of forming a lock nut and the product thereof in which a coaxial extension is secured to the end face of a standard nut to receive a locking element therein. The extension is comprised of a concentric metal ring secured at one edge to the end face of a standard nut and at the other edge secures a locking element against the end face of the nut.

Abstract: A prevailing torque type lock nut for assembly onto a threaded bolt that affords a substantially 360 degree break loose torque engagement resistance against the standard bolt threads and is comprised of a compressively controlled height reduction as compared to a standard nut of like size.

Abstract: A ceiling box construction for supporting a relatively heavy hanging load such as a ceiling fan from the underside of a ceiling and comprised of an electrical junction box having lateral inwardly extending tabs.

Abstract: An electrical junction box to be used when supporting a relatively heavy hanging load from the underside of a joist/beam at an installation site. In one embodiment a slotted pancake dish internally supports an arcuately displaceable bracket both of which have coincident slots through which to receive fasteners by which the load is to be supported. A removably disposed lead box in which electrical leads are received extends normally upright to the plane of the pancake dish and is adapted to he positioned thereon off center in communication with an opening through the dish. A partially circular shell section can optionally be utilized by being removably secured on the pancake dish opposite the lead box so as to cooperate with the lead box when utilized in forming an externally appearing cylindrical canister-like configuration.

Abstract: An improved hanger assembly for the support of heavy hanging loads at the underside of a ceiling. The assembly is longitudinally expandable via a threaded rod secured between relatively displaceable longitudinal bars in which the rod includes an allthread having a double to triple lead for increasing the expansion rate while teeth at the distal end of each bar are configured to arcuately displace inward of the joists in the course of joist penetration to effect a grasping penetration therewith.

Abstract: A hanger assembly for supporting a vertical load at a selected site flush mounted beneath the underside of a drop ceiling. Comprising the assembly is a pair of bars normally intersecting in T formation and mounted onto the T rails of a lattice framework supporting the individual ceiling panel at the selected site. The bars can be variably positioned so as to intersect at any selected site location and by means of a bracket are permanently secured together with a junction box at the underside of the intersection. The bracket in turn is connected for static loading to a depending chain attached to the building structure above the ceiling and adjustably rendered taut to a predetermined tension by means of a turnbuckle attachment. For supporting an attached load, the load bolts have flat heads with canted ends and depend through apertures in both the top wall and ears of the junction box.

Abstract: An interjoist hanger assembly for supporting items to be hung is formed of a pair of elongated tubular sleeves interfitting telescopically slidable one within the other. Supported at the distal end of each of the sleeves is an axial screw and a floating collar having circumferentially distributed axially extending prongs or teeth. The sleeves effect an interlock when collapsed whereby they can be rotated in unison for threading one end into an adjacent joist. When the sleeves are expanded, the opposite sleeve end can be similarly threaded into the opposite joist. With each threaded attachment, the prongs of the surrounding collar are drawn into a gripping engagement with the joist surface thereat.A saddle secured snap fit onto the outer sleeve includes side flanges to which an electrical outlet box can be mounted for attachment of an item to be hung.

Abstract: A self-locking nut has an annular body, an axial threaded bore, and a hexagonal exterior periphery. A small bore is drilled through the body parallel to the threaded bore adjacent to an apex of two peripheral flat surfaces. An L-shaped locking pin has a base leg received in that small bore, and an interference leg projecting into the threaded bore for interference relation with a mating bolt. The distal end of the base leg is provided with an outwardly facing recess, and this distal end is retained within the nut body by cold flowing body material into that small bore and recess. The recess includes two abuttment surfaces which are disposed in planes inclined away from a plane parallel to the base leg and perpendicular to a plane defined by the two pin legs. These abuttment surfaces coact with the nut metal displaced into the recess to allow for rotation of the distal end of the base leg through an arc less than that required for the interference leg.

Abstract: A heavy duty press mechanism, whose ram is driven by means of an eccentric crank and pitman, carries a head with four aligned indention punches for distorting thread pitch simultaneously on four axially aligned hex nuts. A feed track system feeds a row of axially aligned hex nuts under the punch head. A reciprocating ejector-stop, synchronized with the punch ram, simultaneously ejects a group of four indented nuts and defines a stop for the following group of nuts at the indention station. A feed system includes an axial feed track for feeding nuts to the indention station, a lateral feed track, and a transfer speed coupler coupling these tracks. A vibrating hopper feeds laterally aligned nuts into the lateral feed track, where a single row of side-by-side nuts is fed by gravity to the speed coupler. The speed coupler effects a transfer from lateral feed to axial feed into the axial feed track.
