Abstract
A tube bender having a swivel connection of the handle to the shoe for facilitating readjustment of the handle in providing tube bends of greater than 90.degree., while avoiding crossover of the tube handle with the mandrel handle. The shoe handle includes a cylindrical extension rotatably received in a socket in the shoe and structure is provided for automatically disposing the handle in either of preselected dispositions. The extension is caused to be disposed in an overcenter arrangement in the preselected dispositions so as to cause forces generated on the shoe handle during the bending operation to more firmly lock the handle in the preselected disposition. A friction washer is provided for biasing the shoe handle to provide releasable retention thereof in the preselected positions.
