ABSTRACT:
A handle assembly for producing rotational movement in a milling machine quill and a quill shaft member defining a plurality of bores. The handle assembly comprises a member engagement housing including two bores positioned in confronting relation with the quill shaft member bores when the housing is operatively connected to the quill shaft member such that the housing is capable of rotation relative to the quill shaft member. An actuating handle member is pivotally connected to the housing and movable between a structure engaging position and a structure releasing position. Two pins are slidably supported in the housing bores and each pin defines a notch near an inner end with the notch being sized to receive a peripheral portion of the actuating handle such that movement in the handle between the structure releasing and structure engaging positions produces concurrent movement in the pins. When the pins are aligned with two selected quill shaft member bores, the pins move into the selected bores when the actuating handle moves to the structure engaging position thereby preventing rotation of the housing relative to the quill shaft member. A spring is provided for biasing the pin toward the structure engaging position.
