PEDRAIL
Ped"rail`, n. [See Pedi-; Rail.] (Mach.)
(a) A device intended to replace the wheel of a self-propelled
vehicle for use on rough roads and to approximate to the smoothness
in running of a wheel on a metal track. The tread consists of a
number of rubber shod feet which are connected by ball-and-socket
joints to the ends of sliding spokes. Each spoke has attached to it a
small roller which in its turn runs under a short pivoted rail
controlled by a powerful set of springs. This arrangement permits the
feet to accomodate themselves to obstacles even such as steps or
stairs. The pedrail was invented by one B. J. Diplock of London, Eng.
(b) A vehicle, as a traction engine, having such pedrails.
