ABSTRACT:
A pair of side-by-side augers, each having a shaft, a mateable rotational coupling on each end of the shaft, and flights along the shaft, are unitized by journaling bearings on each end of the shaft with spacers pivotally attached between each of the bearings on the same end of the shaft in order to align the axis of the shafts substantially parallel with each other. A longitudinal support member is rigidly secured between the spacers and between each of the flightings. A communications channel is provided in such a unitized auger assembly by mounting a channel along the top of the longitudinal support member. Apparatus is provided for inserting and removing the cable from the channel.
