  • Patent number: 4892016
    Abstract: An adjustable socket having a driver rotatably drivable about a central axis, wherein the driver includes inclined slideways extending with both radial and axial components with respect to the central axis. Jaws are supported within corresponding slideways of the driver for movement with respect to the central axis. The jaws each include an internal driver aperture having an axis transverse to the central axis. An adjuster provided with the socket includes a jaw operating member, jaw clips and a connection that secures the jaws, jaw operating member and jaw clips, to maintain the socket in the assembled condition and to limit inward movement of the jaws. The jaw operating member includes an annular flange projecting outwardly in a radial direction with respect to the central axis to axially locate the jaw clips.

  • Patent number: 4842025
    Abstract: A wire twisting tool that includes a pair of jaws for clamping wire ends to be twisted and a removable spin drive unit for imparting rotation to the jaws to effect twisting of the wire ends. The spin drive unit is threadedly attached to a housing that encloses a spiral drive shaft. A pair of shaft engaging elements is mounted in a spaced apart relationship within a tubular carrier that forms part of the spin drive unit. The one end of the carrier is threaded and threadedly engages the housing. One of the shaft engaging elements is fixed to the carrier so that as the shaft is pulled through the drive element, rotation is imparted to the carrier. The other element slidably supports the drive shaft in order to maintain it in a predetermined alignment with respect to the carrier. In one embodiment, the support element is fixed to the carrier whereas in another embodiment it is free to move within the carrier to accommodate a change in pitch in the spiral shaft.
