ABSTRACT:
A method and arrangement for reciprocating a piston in a cylinder of a fluid actuated actuator between one and another alternate positions, and using the piston fluid actuator fluid to move a lock member from a first position to a second position to lock the cylinder when it is moved from one position to its other alternate position. Actuator fluid is communicated to unlock the lock member and to move the piston back to its one position. In another form, the lock member is moved to its first position by the actuator pressure fluid which actuates a valve to communicate actuator fluid pressure from the lock member to the cylinder to move the piston back to its said other position.
