The general features ofits construction are the fol-lowing : It comprises amain building surmountedby what is termed the cupo-la. The main driving-en-gine is situated <n\ about theground level, at one end ofthe building. Along the topof the cupola a counter-shaft, the full length of thebuilding, is carried. Thisis driven by the main belt is of India-rubber and canvas, 8-ply inthickness and GO in. runs very nearly verti-cally from the engine driv-ing-pulley to the pulley onthe counter-shaft 150 it. All along thecountershafts are the driv-ing-pullevs for working the28 elevator-belts. Tiiesebelts are made also of India-rul)!)er belting, and carrysteel buckets riveted at reg-ular intervals along theiroutside face. As the belttravels »ip on one side itcarries up full liuck(^ts. At.

From flic i)oint of deliverv of the belt the graiiipasses l)y gravity through inclined chutes to tlie nuiin body of tlie elevator, and is directed bvone or the other of the chutes to any desired point. The grain from the elcivating-belt fallsinto the mouth of a chuto which rotates on a vertical axis, whoso prolongation would pass ELEVATOES. 251
