  • Portable pipe bending machine
    Patent number: 4719783
    Abstract: A portable pipe-bending machine that makes uniform and consistent bends of varying degree curvature in pipes is disclosed. The pipe-bending machine has a stabilizing platform to resist counter-bending forces and interchangeable elements to accommodate pipes of a different thicknesses. The pipe is forced between a solid mandrel and a movable semi-sleeve in a rotation yoke and the yoke is moved at a pre-set number of degrees, thereby putting the desired bend in the pipe.
