Abstract: A connector apparatus for releasably securing two separate force transmitting assemblies in a force transfer relationship is disclosed. A first connector assembly having a tubular member forming a central opening having a locking recess formed therein is anchored at a desired location. A second connector assembly having a primary and a secondary housing operably connects with the first connector assembly for transferring the static forces therebetween. The primary housing mounts an expandable locking ring which fits in the recess of the first connector assembly for effecting the mechanical securing.

When released, all operating parts of the connector except the first connector assembly may be retrieved to a convenient location for inspection or repair. Should the locking ring fail to release by either mode, the secondary housing may in the alternative be released from the primary housing.

Abstract: A bight of a cable is wrapped around a sliding wedge thimble which, when one or both of the cable parts is pulled, jams the cable parts between convergent sides of the wedge thimble and opposed convergent sides of a casing. A key, when engaged through registering keyways of the wedge thimble and casing, limits the sliding movement of the wedge thimble so that the latter does not jam the cable parts but, rather, permits the cable to slip lengthwise around it. The key is tapered, and the keyways are so arranged that they serve to unjam the cable when the key is forced through the keyways.

Abstract: A pair of structural members are coupled by a tongue and groove joint hav a groove half and a tongue half. To secure the joint, bolts extend transversely through aligned bolt holes and, on each side of the tongue half holes, are so-called `collapsing` slots. A linear explosive is placed in the base of the groove near the inner end of the tongue. The metal thickness of the tongue lying between the explosive and its holes and slots forms a `web` which, upon detonation, collapses into the slots. The collapse stretches the web portion adjacent the bolt holes sufficiently to produce a rupture or opening through which the bolts pass to permit separation of the structural members. The separation also is responsive to the explosive force so that the members are accelerated apart in opposite directions.

Abstract: A pivot pin assembly for mounting a loader bucket to a loader arm of a tractor. The pivot pin assembly includes a cylindrical pin having spaced-apart retaining sleeves which capture a sleeve bearing therebetween. The retaining sleeves engage the bucket bracket assembly and the bearing engages the loader arm assembly. Flanges on one retaining sleeve engage the bucket bracket assembly to restrict axial movement of the pin in one direction. A cover plate, secured to the bucket bracket over the flanges, restricts axial movement of the pin in the other direction. The flanges define two spaced-apart sides which are retained in a channel on the cover plate to prevent rotational movement of the pin with respect to the loader bucket. The pivot pin assembly may be removed by detaching the cover plate and pulling the pin from the bucket bracket assembly and the loader arm assembly.

Abstract: A coupling unit for coupling a shaft to a surrounding hub has an inner ring which surrounds the shaft and is in turn surrounded by an outer ring. The juxtaposed surfaces of the two rings define with one another two wedge-shaped annular gaps which taper towards each other axially of the rings. Tension members are inserted into these gaps and both extend through the tension members so as to draw them axially together in order to force the rings against the shaft and the hub, respectively. An abutment ring is located between the inner and outer rings and has circumferentially spaced bores some of which are smooth and some of which are tapped. By cooperation of the bolts and the abutment ring the tension members can be forced out of the respective gaps when the connection between shaft and hub is to be released.
