ABSTRACT:
A linear control latch assembly controls the clutching operation of a power take-off system. A driving means produces kinetic mechanical energy which is taken off by a power take-off means. Clutch means effects a union between the driving means and the power take-off means. A linear actuator operates the clutch means. The linear actuator is controlled by a crank arm cranked into operation by a control lever. The control lever is rotated before the crank arm rotates as a result of lost motion in the control system. The initial motion of the control lever is translated into a camming action that unlatches a latch plate prior to the rotation of the crank arm. When the latch plate is unlatched, it unlatches the crank arm to allow release of the clutch that effects the union between the driving means and the power take-off means.
