Definition of Pedrail
Pedrail 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.
