Abstract

1,166,420. Treadle drive mechanism. S. CORNFORTH. 2 May, 1968, No. 20937/68. Heading B7E. A treadle drive mechanism for use with a bicycle comprises a pair of free-wheel sprockets 25, 26 both connected to drive in the same direction a rear wheel spindle 27, there passing around the sprockets the two runs of a driving chain 28 which is looped around an idler sprocket 22 suspended from a frame 15, said chain runs each passing round one of a pair of sprockets 3, 4 before being fastened to a fork 20 at 30, the sprockets 3, 4 each being supported by a lever 1, 2 respectively, pivoted about a spindle 5 and connected respectively with treadle levers 6, 7 extending at 90 degrees therefrom, there being provided resilient stop means 42 to limit the travel of the levers 1, 2 and a further chain 37 to tension said chain 28. Reciprocating action on the pedals 12 will alternatively move forward the upper runs of the chain 28, the driving of the spindle 27 taking place when the sprockets rotate in a clock-wise direction. The tensioning chain 37 passes round a second idler sprocket 21 and and has its ends attached to sprocket segments 33, 34 at 35, 36, said segments being connected with levers 1 and 2 to rotate therewith. The axes of the idler sprockets are inclined with respect to the axes of spindles 27 and 5.
