Abstract: This invention pertains to an improvement in box joint tools and particularly for reducing play resulting from wear of the members forming the box joint. The box joint is formed in the usual manner. This improved joint is used when or where wear develops or may be utilized with new tools at the time of assembly. A first portion outer member of the box joint is machined to provide a counterbore and an enlarged bore in this member portion. A counterbore is also formed in the second outer member portion and extends to about one thirty second of an inch from a central jaw tongue portion. This counterbore provides a flexure portion with a smaller bore axially coincidental with the axis of the central portion. A pivot pin bushing has a threaded bore and is sized to be a press fit in the formed counterbore and enlarged bore of the first outer member. This bushing is mounted in the first outer member and the shank portion extends into the tongue portion of the central jaw.

Abstract: The push frame (12) of a tractor-scraper (10) normally has a plurality of cover plates (14) relasably secured therebelow to provide access internally of the push frame. In standard practice, the cover plates are secured to the push frame by a plurality of bolts and the heads of the bolts are subjected to wear and possible breaking-off due to their exposure upon operation of the tractor-scraper. This invention provides a mounting assembly (13) for expeditiously removing and replacing the cover plates upon wearing or breaking-off of the heads (19) of bolts (18) thereof by providing an internally and externally threaded bushing (24) which is threadably connected on the push frame and is further threadably connected to each bolt. Thus, a workman need only engage the bushing with a socket wrench or the like to release the bolt and thus the cover plate upon wearing or breaking-off of the heads of the bolts.

Abstract: A novel fastener assembly is disclosed for use in securing a frame section to a composite panel or the like, said fastener assembly being dielectrically insulated from said frame section to prevent galvanic action. The fastener assembly is comprised of a bolt member adapted for engagement in a bore formed in said frame section, said bolt member having an enlarged head portion including annular axially facing groove means, and an annular axially extending non-conductive elastomeric gasket member disposed in said groove means, and a nut member having an enlarged head portion for engagement with said bolt member. The nut member is disposed in a coaxial bore formed in said composite panel and engaged with said bolt member also disposed in said bore. Upon assembly the gasket member is clamped between the frame and the enlarged head on the bolt and is deformed axially and radially.

Abstract: A self-retaining safety bolt assembly having a headed end, a cylindrical shank, and a pin tail nut with a tubular shank telescoping over the cylindrical shank with means near the headed end to retain the tubular shank on the cylindrical shank in a hole in a workpiece. An axial passage opening into the headed end intercepts a laterally-extending passage wherein a dog is laterally reciprocable so as to be extendable beyond a maximum diameter of the cylindrical shank or to be entirely retracted within it. A cam member having a pair of oppositely facing cam surfaces is axially slidable in the axial passage. The dog has a pair of followers, one on each side, bearing against the oppositely directed cam surfaces whereby the lateral position of the dog is uniquely a function of the axial position of the cam member.

Abstract: A grommet attached to a top panel captures a stud nut of a panel fastener through a retaining ring held by the grommet. A complimentary stud assembly attaches to a subpanel and receives the stud nut to clamp the panels together. The grommet has a stand-off base that projects axially from a counterbore in the top panel to form a barrier for a gasket. A flared end of the grommet and the standoff base clamp the top panel between them. The retaining ring compressively bears radially against the stud nut to retain it in any desired axial position and maintain axial alignment of the stud nut. The stud nut can draw completely into the top panel. The stud nut has a clear-through bore threaded at one end. A wrenching recess, defined by a hardened insert, occupies the other end of the bore. A plug separates the wrenching recess from the threads. A basket of the stud assembly attaches to the subpanel by rivets. A barrel attaches to the basket through lugs engaged in slots of down turned wings of the basket.
