Abstract

See full text

A device for securing a spindle to a hub in a mortise lock for a door. The device includes a hub defining a central opening about an axis of rotation and a spindle with a first end adapted to be received in the opening in the hub to apply rotational force to the hub. A securing element is moveable between a first position in which the securing element engages the spindle and the spindle is secured to the hub, and a second position in which the securing element is disengaged from the spindle and the spindle may be freely removed from the opening in the first hub. The securing element may be adapted for reciprocal linear movement in the housing, and may engage the first spindle by part of the securing element being received in a peripheral groove in the spindle.
