Latest Patents
One of his latest patents is for a positioning means that involves a rail-car positioner. This device comprises a carriage on a track running alongside and parallel to the train track. An elongate arm on the carriage is transversely displaceable to enter between a pair of coupled rail-cars of the train, connecting the positioner drivingly to the train. The arm extends substantially axially from a retracted position on the carriage, moving in a generally horizontal first direction to introduce an end of the arm between the rail-cars. The end is then engaged with the rail-cars' coupling by displacing it in a second direction transverse to the first direction.
Another significant patent by Evans is for rail wheel grippers. This invention is designed to hold or retard a rail vehicle using opposed gripper mechanisms that engage a wheel between them. Each mechanism includes a carrier arm for a gripper member and upper and lower pivot arms connected to the carrier arm, controlling the path of movement of the gripper member. The design allows for a mechanical advantage with increased gripping force when the gripper members reach their operative positions.
