122. Whitaker, A., [Preston, G.]. Jan. 2. Pedals for bicycles, tricycles, &c. are formed with resilient treads. The pedal plates d, d<1> have sockets g, which slide on sockets a<1> formed on a frame a mounted o the axle b, and are pressed outwards by springs c enclosed in the sockets g, a<1>. Loops f, formed on the ends of the plates d, d<1>, limit the outward motion of the plates as shown. By turning the plates d, d<1> into a vertical position, the pedal can be used as an ordinary rigid tread pedal.
