ABSTRACT:
The self-counterweighted take-up assemblies disclosed herein are especially adapted for use with endless conveyor systems comprising a headshaft, a footshaft, an endless conveyor trained around the headshaft and the footshaft, and a first frame which is immobile relative to the headshaft. Speaking broadly, two general types of self-counterweighted take-up assemblies are disclosed herein. In the first, a second frame is pivotably mounted about an axis parallel to and spaced from the footshaft, take-up bearings journalling the footshaft are mounted on the second frame, and means are provided for moving the footshaft in the take-up bearings in order to maintain tension in the endless conveyor as it varies in length, permitting the second frame to pivot about its axis. In the second, a wire rope is connected to each end of the footshaft and the wire rope[s] is or are connected to the first frame so as to maintain tension in the endless conveyor as it varies in length.
