  • Patent number: 7981189
    Abstract: The invention has a captive tooless fastener for securing the engine intake air filter. The tooless fastener comprises shaft and associated bodies. The body has two arms oriented about 180 degrees apart. The shaft is threaded through a sealing washer and an aperture in a closed end cap of the air filter. The shaft is expanded so it cannot be removed from the end cap. The body's threaded inner diameter mates with a threaded portion of a central shaft in an air filter housing. The body's arms are rotated to screw the fastener and the shaft of the housing together. When tightened, the sealing washer closes the aperture. To remove the air filter, the fastener is unscrewed from the shaft of the housing and in the shaft floats in the aperture. A person in the field can remove the air filter by inserting fingers under the arms and pulling.

  • Patent number: 6089807
    Abstract: A bolt-and-nut joint wherein the nut can be quickly relocated to an operative position on the bolt without deteriorating the locking function of the nut. In one aspect of the invention, a nut is provided with an axial slot extending through a wall of the nut. The width of the slot is somewhat smaller than the diameter of the bolt and the nut is produced of an elastic material that allows the nut to be snapped on and off the bolt via the slot at variable positions along the length of the bolt. The nut is tapered near one end for cooperation with a corresponding conical recess in a washer. The taper of the nut and the recess in the washer are chosen so that when the nut is tightened, the tapered part of the nut is wedged into the recess, urging the side walls of the nut to tighten around the bolt.

  • Patent number: 5319691
    Abstract: A method and an apparatus for locking the tie rods to block rotation relative to either the upper or lower tie plates utilizing the required fuel bundle channel. A conventional lock nut is provided for threading to the upper threaded end of the tie rods. This lock nut has attached extending wings, these wings when rotated interfering with a placed fuel bundle channel. In installation to the fuel bundle, and assuming that the tie rod has been fully threaded to the lower tie plate, the winged lock nut is rotated overlying the upper tie plate to cause full engagement of the upper tie plate to the tie rods. In such fastening, the winged lock nuts are rotated to an angle that provides no interference with the subsequently placed channel. Thereafter, and when the channel is placed, the channel interference with the rotational path of the wings of the lock nut and thus prevents relative rotation between the tie rod and winged lock nut.

The expandable plug includes a threaded bolt, a compression plate assembled with the bolt, and a compression nut assembled with the bolt and adapted to bear against the compression plate. A resiliently deformable section of tubing is assembled in slip fit relation with the bolt, the tubing section being axially compressible and radially deformable but not being a specially molded part. With the plug located within the pan's drain hole, tightening of the compression nut causes the tubing section to bulge outwardly into a liquid sealing with the hole, and also to bulge inwardly into liquid sealing relation with the bolt, thereby plugging the drain hole against oil flow therethrough.

  • Patent number: 4482368
    Abstract: An improved fastening assembly having application for securing a filter element within an air cleaner and incorporating a novel wing nut construction. As used with an air cleaner, the wing nut is engaged with a large diameter threaded portion of a connecting bolt and acts to secure a filter element within an air cleaner housing, while an outer knob is engaged with a smaller diameter threaded section of the bolt and bears against a cover to secure the cover to a housing. The wing nut is provided with an inner threaded metal section which is molded within an outer plastic wing section. The inner nut portion includes a plastic ring having an inner diameter slightly less than the thread on the nut and serves to seal against the thread on the bolt and prevent leakage of air along the threaded connection, as well as preventing the loosening of the threaded connection due to vibration.

  • Patent number: 4472097
    Abstract: Torque limiting clamping and sealing means comprise a cylindrical unthreaded screw-thread engaging clamping member of elastomeric material screwed on a rigid screw threaded member at an interference fit. An annular abutment around the clamping member engages a stop fixed with respect to the rigid member at a predetermined limit of screw induced axial travel to effect said limit of travel. A thin, flexible annular sealing lip around the clamping member and spaced radially from the abutment sealingly engages a surface fixed with respect to the rigid member prior to said limit of axial travel.

  • Patent number: 4472098
    Abstract: Torque limiting clamping means comprises a cylindrical unthreaded screw-thread engaging clamping member of elastomeric material screwed on a rigid screw threaded member at an interference fit. The interference fit, the pitch and dimensions of the screw thread, and the physical characteristics of the elastomeric material are preselected to enable deformation of the elastomeric material resiliently within its elastic limit into the thread groove of the rigid member to accommodate the interference fit and to cause screw induced relative axial movement of the members to a limit of axial travel, whereupon the elastomeric material flows axially across the screw thread to terminate the axial travel and to effect a resilient reaction against the screw thread which results in an axial clamping force and a radial thread-locking force against the thread predetermined by the maximum allowable torque.

  • Patent number: 4433578
    Abstract: A wing nut with a threaded axial passage is adapted to engage the threads on the horizontal balancing shaft of a wheel balancer having an abutment thereon. A wheel to be balanced is placed on the shaft and is arranged to be held in tight engagement with the abutment when the wing nut is threaded on the shaft. The surface of the wing nut which forces the wheel against the abutment is recessed with a cylindrical recess. A plastic insert is adapted to be retained within the cylindrical recess and has a central bore which is aligned with the threaded passage in the nut to permit the balancing shaft to pass therethrough. The insert projects axially from the nut body so that the insert, rather than the nut body, will engage the member which is holding the wheel against the abutment.

  • Patent number: 4374453
    Abstract: A bicycle freewheel wrench pry adapter for use with a freewheel wrench in removing a freewheel and its associated drive sprocket assembly from the bicycle axle is generally U-shaped and includes a channel in the base of the U opposite the legs of the U which fits the boss of the freewheel wrench engaged with the freewheel. The adapter includes a recess in the root of each leg of the U to assist in retaining a pry inserted between the legs for applying force through the freewheel wrench to the freewheel. The freewheel wrench pry adapter channel includes stress reliefs in the corners of the channel to avoid excessive stress concentrations in such corners which could induce breakage of the freewheel wrench pry adapter.

  • Patent number: 4345110
    Abstract: A screw on electrical connector, commonly called a "pigtail," of a type which is generally made up of a tubular insulating cap closed at one end and open at the other end and a tapered helically wound resilient wire coil or spring nested and anchored in the cap, which is constructed and arranged to be screwed down on the stripped ends of two or more wires, and having one or more longitudinally extending levers, each of which is outwardly pivotally connected at one end thereof to the cap at or near the open end thereof. The levers are "L" shaped, each having an axially extending inwardly directed foot at one end thereof, and these feet are axially slidably connected to the cap at the closed end thereof. The cap may contain one or more inwardly directed recesses or channels, each keyed to a respective lever, so shaped and so disposed as to receive its respective lever. The levers may be outwardly pivotally connected to the cap by a resilient plastic means.
