Abstract: A child carrier comprised of a seat-mounting frame and a lower wheel frame assembly depending downwardly from the mounting frame, the wheel frame assembly including front and rear wheels supported for downward extension from the wheel frame assembly, and a seat portion disposed on the seat mounting frame. A handle has side frame portions extending from opposite sides of the seat-mounting frame terminating in a hand-engaging, angled end extending rearwardly from the side frames with the handle member pivoted to the seat mounting frame for pivotal movement of the handle about a horizontal axis from a first position in which the handle extends rearwardly from the seat mounting frame when used as a stroller to a position in which the handle is directed downwardly from its pivotal connection to the seat mounting frame such that the angled end thereof is disposed beneath the wheels in order to support the carrier on a car seat when used as a car seat carrier.

Abstract: A pedal driven vehicle such as a bicycle which employs oscillating levers instead of crank type pedals, and endless chain to which the two pedal levers are respectively connected, one to each run of the chain by pull and push rods to impart an oscillatory movement to said chain and in which the oscillating chain is connected to drive two shafts in opposite directions at any one time and means including one way drives connecting said shafts respectively to the drive wheel for propelling said vehicle. The vehicle also has means for simultaneously moving the connections between said pull and push rods and the oscillating levers respectively along the lengths of said levers in the same direction so as to change the effective leverage of said levers and to thus change the driving ratio imparted to the propelling wheel by the drive mechanism.
