Abstract
A latch tool features two elongate arms which extend down along either side of a control rod. Rotatable actuating rods are mounted on the arms. The upper ends of the actuating rods are provided with cranks which engage in slots formed in an actuating disc. As the disc is rotated, the cranks rotate the actuating rods and swing cam-like members, which are fixed to the rods, into position under an unlatching handle. In the preferred embodiments, the actuating disc is threaded onto the exterior of a rotatable input member, so that after the cam-like members are swung into position, the actuating disc threads its way up the input member in a manner which pulls the cam-like members upwardly and pulls the unlatching handle. In addition to the cam-like members which actuate the unlatching handle, lifting cam-like members may additionally be provided to fit in under a lifting handle of the control rod, and facilitate lifting of the control rod out of its position.
