Abstract

620,226. Gearing for conveying rotary motion. BASCLE, C. E. Jan. 10, 1947, No. 829. Convention date, Jan. 22, 1946. [Class 80 (i)] [Also in Group XXXI] In a driving mechanism for a bicycle each pedal crank 1a is pivotally connected to one end of a rod 3a slidably mounted in a guide 4a which is rotatably mounted on the driving sprocket shaft 6 and connected to the sprocket 8 by freewheel mechanism. The pivotal connection between each rod and its pedal crank is co-axial with the pedal. The pedal cranks may be replaced by handactuated cranks.
