Abstract

617,226. Tensioning driving belts. BECHLER, A. Aug. 22, 1946, No. 25114. Convention date, May 3. [Class 80 (i)] In variable speed belt gearing in which a countershaft 11 carrying a stepped cone pulley 12 is interposed between the driving and driven shafts 9, 6, the bearings of the countershaft are formed integral with a frame 14 having a longitudinal slot 20 crossed by a slot 22 in the fixed machine-frame, both the slots being traversed by a fixed pin 21, provided with a lock-nut, release of which permits the countershaft frame to be both oscillated and translated to tension both belts. The countershaft frame 14 may, as shown, swing on parallel links 16 or on a fixed pin engaging a slot in the frame 14.
