Abstract
A portable chain type pipe vise that includes a frame, at least two clamping main assemblies, and a clamping sub-assembly. The frame is stably restable on a work surface. The at least two clamping main assemblies are longitudinally movable on the frame, so that at least two pipes can be rested in longitudinal alignment with each other. The clamping sub-assembly is disposed at each of the at least two clamping main assemblies, so that the at least two pipes can be retained in longitudinal alignment with each other.
Claims15
A portable chain type pipe vise, comprising:
- a) a frame resting on a work surface in a stable manner when said portable chain type pipe vise is being utilized;
- said frame including an inverted substantially U-shaped first end plate having a top and a pair of apertures disposed in proximity to said top of said inverted substantially U-shaped first end plate of said frame;
- said frame further including an inverted substantially U-shaped second end plate displaced a distance from, and parallel to, said inverted substantially U-shaped first end plate of said frame;
- said inverted substantially U-shaped second end plate having a top and a pair of apertures disposed in proximity to said top of said inverted substantially U-shaped second end plate of said frame;
- said frame further including a pair of parallel rods;
- each of said pair of parallel rods of said frame having a pair of rod ends;
- one of said pair of rod ends of each of said pair of parallel rods of said frame being disposed in said pair of apertures of said top of said inverted substantially U-shaped first end plate of said frame;
- another one of said pair of rod ends of each of said pair of parallel rods of said frame being disposed in the pair of apertures of said top of said inverted substantially U-shaped second end plate of said frame;
- b) at least two clamping main assemblies longitudinally movable on said frame so as to allow at least two pipes to be rested in longitudinal alignment with each other;
- each of said at least two clamping main assemblies including a pair of parallel substantially square-shaped plates;
- each of said pair of parallel substantially square-shaped plates of each of said at least two clamping main assemblies having a top with a V-shaped recess disposed thereon for receiving the at least two pipes, a bottom with a pair of apertures disposed therethrough, a front having an extension with an aperture disposed therethrough, and a back;
- and
- c) a clamping sub-assembly disposed at each of said at least two clamping main assemblies so as to allow the at least two pipes to be retained in longitudinal alignment with each other.
