ABSTRACT:
A loader comprising an upright frame having only two elevators or rams for transferring parts from one to the other and raising them to a point where they may be discharged. One ram moves up while the other moves down. They meet at a midpoint where parts are transferred from one to the other after which one ram goes down to pick up another load of parts and the other rises to an upper limit where the parts are discharged. A simple rack and gear drive is employed. Switches are provided to reverse the motor at the ends of the ram travel.
