Abstract

6225. O'Dwyer, S. March 13. Treadle mechanism.-In treadle mechanism for bicycles &c., of the kind in which treadlelevers c pivoted on downward extensions b of the frame are connected by chains, cords, or the like f to pulleys mounted by free-wheel clutches upon the rear-wheel hub, the pulleys are in the form of fusees or scrolls d, so arranged that the greatest leverage is in action at the commencement of the downward stroke and the least leverage at the finish of the stroke. The levers are returned to their uppermost positions by a spring or the equivalent connected to the respective scrolls or fusees. The cord f passes over a guide-wheel g upon the chain stay. Speed gear may be interposed between the scrolls and the wheel.
