Abstract
A telescopic belt tensioner includes a pair of housings mounted to the sides of a conveyor bed. Each housing has an outer tube telescopically mounted in it, and an inner tube telescopically received within the outer tube. The inner tube includes means for rotatably supporting a conveyor belt roller. Bolt and nut means between the inner and outer tubes reciprocate the inner tube with respect to the outer tube to provide fine adjustment of the belt tension. A quick release mechanism between the housing and outer tube provides rapid adjustment of belt tension. The quick release mechanism comprises a lever mounted to the housing and a hook mounted to the outer tube, with a pivotable link connecting the lever and hook.
