Abstract
There is provided, in a railroad car positioning apparatus of the general type shown and described in Reissue Patent No. Re. 27,300 dated Feb. 22, 1972, an improvement in the car positioner arm which is adapted to move between a pair of coupled railroad cars and into car pushing engagement with the cars centrally thereof. The improvement involves the provision, in combination, of force transferring means on the distal extremity of the car positioner arm for engaging a coupled coupler between a pair of coupled railroad cars, separate force transferring means also on the distal extremity of the car positioner arm for engaging an open coupler of at least one uncoupled railroad car, and means for shifting the two force transferring means for selectively disposing either of them in its operative, car-manipulating position and the other in a stored or inoperative position.
