Abstract: A device for gripping and hoisting packed sacks includes a contrivance for mounting the device onto a hoisting machine, load bearing members rigidly coupled to the contrivance for mounting the device onto a hoisting machine. The load bearing members carry vertical plates hinged thereto and turnable from an actuator. The free ends of the load bearing members has slots whose longer faces are in a position of angularity with respect to the end faces of the load bearing members. The device incorporates also two rods arranged parallel to each other, of which the rod is rigidly fixed with its ends to the vertical plates while the other rod is fitted in the slots of the load bearing members. The load bearing member carries a mechanism for restricting the load upon the actuator imparting turning motion to the vertical plates, said mechanism being kinematically associated with the rod fitted in the slots of the slots of the load bearing members.

Abstract: A crop pickup mechanism for a crop harvesting farm machine having an endless driven conveyor between laterally spaced rigid side members of a frame. The side members have connected thereto a forward shaft and a rear shaft mounted transversely of the frame on self-aligning bearings. A sectional crossbar is connected to the side member and is made as two rigid sections connected at a pivotal connection for relative rotation of the sections about the longitudinal axis of the crossbar. The shafts maintain the endless conveyor with substantial parallelism with ground of a field sloped in a direction transversely of the side members. The side members are thus relatively movable upwardly and downwardly as the wheels on which the frame is mounted travel over the sloped ground of the field. Crop-engaging pickup fingers on the conveyor pickup the crop being harvested for transport thereof on the conveyor.
