Abstract
A device for twisting a conventional J-shaped wire preform into a hangwire has a rotatable hook by which the closed end of a preform is held and a wall spaced therefrom has an upwardly opening slot in alignment with the hook axis and overlying a ledge. The slot is spaced from the hook a distance such that both arms of the preform can be entered and then held against turning by a hold down arm. The hook is rotated by a gear train provided with a crank with the gear train providing mechanical advantage to the user and enabling the length of the crank arm to be less than the distance between its axis and the base of the device. The hold down arm has a first inoperative position in which it depends vertically, its position when the device is shipped or stored, and a second position for use during hangwire production in which position the arm is held upwardly but tilted away from the slot.
