Abstract
Abstract Disclosed is a vehicle driven by a pair of pivoted levers operated by foot pedals and swingable forwardly and rearwardly and each connected by a driving cable to a drum rotatably mounted on a wheel-carrying rear axle, each drum being in turn drivably connected by a gear type ratchet to a rear wheel and resiliently urged in a direction to cause the cable to rewind therearound and thereby retract the associated foot pedal, upon its release, to its rearwardmost position for subsequent driving action upon the rear wheel.

315 words
A foot-operated vehicle comprising: a. a wheeled frame, b. seat means carried by said frame, c. a pair of rear wheels each rotatably mounted on said frame, d. a pair of foot levers each pivotally mounted adjacent one of its ends upon said frame ahead of said seat means and constructed and arranged to be moved by the feet of a rider sitting upon said seat means from a rearward to a more forwardly extending position, e. a pair of foot pedals each carried by the opposite end of one of said levers to facilitate such movement of said foot levers by such a rider, f. a pair of rotary gear means each connected with one of said rear wheels in driving relation and mounted for rotation therewith upon said frame, g. a pair of rotary drum means each associated with the gear means of one of said rear wheels and mounted for rotation upon said frame, h. ratchet means extending in driving relation between each of said drum means and its associated rotary gear means, i. cable means extending between each of said drum means and one of said foot levers and constructed and arranged to be moved with respect to its associated drum means between extended and retracted drum-encircling relation, j. resilient means connected to each of said rotary drum means and constantly urging the same to rotate and draw its associated cable means to retracted drum-encircling relation and its associated foot lever to its rearwardmost position, k. said ratchet means including a plurality of pawls pivotally mounted upon and within said drum means in position to engage said gear means and prevent rotatiOn thereof in more than one direction, and 1. said pawls being of single-piece construction and including a spring arm extending outwardly therefrom and engaging against an interior surface of said drum means to hold said pawl in gear-engaging relation.
