Abstract: Plastic surface pipe rotary drive apparatus, comprising in combination a drive rotor rotatable about a central axis; a set of jaws spaced about a central axis, and operatively connected to a rotor to rotate about parallel jaw axes in response to rotation of the drive rotor, the jaws having work engaging surfaces extending eccentrically relative to their respective jaw axes; and each of the surfaces extending generally circularly about a locus offset from a jaw axis associated with the surfaces.

Abstract: Wire or cable pulling apparatus, comprising in combination a stand including an upright pedestal and a base supporting the pedestal; a frame mounted on the pedestal; a rotary axle supported by the frame, and a wire or cable pulling capstan carried by the axle, there also being a coupler associated with the axle for coupling an electrically powered driving tool in rotary driving relation with the axle and capstan; a boom having one end carried by the frame, and an idler carried proximate the opposite end of the boom, for entrainment by the cable or wire being pulled in response to capstan rotation when the boom is in operating position, extending at a first angle relative to the frame, the boom having a stored position in which the boom extends at a second angle relative to the frame.
