Abstract
Abstract A crank centrally located on a desk has an opening in its offset portion engaged by a pin eccentrically mounted on a tumbler lock to translate the rotational motion of the lock directly to rotational motion of a shaft on which the crank is mounted. The shaft extends to either side of the crank to actuate other locking means on each side thereof.
