Abstract
Abstract A ''''walking'''' vehicle having driving wheels connected to the same or individual power source which permits one wheel to be moved forward individually, or any number of wheels at a time, while the other wheels provide the reactive force. After all wheels have been advanced, the entire vehicle body is then moved forward with respect to the wheels. The invention described herein may be manufactured, used, licensed by or for the Government for governmental purposes without payment to us of any royalty thereon.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
160 words
A vehicle comprising a hull; at least four wheels arranged on transverse axles for moving said hull in at least the forward direction; and a suspension means interposed between each wheel and the hull; each suspension means comprising a first powered member operable to raise and lower the associated section of the hull relative to the associated wheel, and a second powered member operable to reciprocate the axle of the associated wheel forwardly and rearwardly relative to the hull; said powered members being independently movable to provide various different combinations of hull elevations and wheel axle positions of reciprocation; each of said first powered members comprising a first crank arm pivotally connected to the hull, and each of the second powered members comprising a second crank arm pivotally connected to the first crank arm; the associated wheel having its axle journalled on the second crank arm so that the crank arms are interposed in series between the wheel and hull.
Claim 2
Dependent Claim
160 words
A vehicle comprising a hull; at least four wheels arranged on transverse axles for moving said hull in at least the forward direction; and a suspension means interposed between each wheel and the hull; each suspension means comprising a first powered member operable to raise and lower the associated section of the hull relative to the associated wheel, and a second powered member operable to reciprocate the axle of the associated wheel forwardly and rearwardly relative to the hull; said powered members being independently movable to provide various different combinations of hull elevations and wheel axle positions of reciprocation; each of said first powered members comprising a first crank arm pivotally connected to the hull, and each of the second powered members comprising a second crank arm pivotally connected to the first crank arm; the associated wheel having its axle journalled on the second crank arm so that the crank arms are interposed in series between the wheel and hull.
Claim 3
Dependent Claim
50 words
The vehicle of claim 1 wherein the first crank arm is arranged to swing vertically between a first inclined position and a second declined position, and the second crank arm is arranged to swing horizontally in pendulum fashion between a first forwardly advanced position and a second rearwardly retracted position.
Claim 4
Dependent Claim
30 words
The vehicle of claim 1 wherein the crank arms are powered by means which includes a fluid cylinder interconnected between each first crank arm and the corresponding second crank arm.
Claim 5
Dependent Claim
93 words
The vehicle of claim 1 wherein each of said first crank arms is arranged to swing vertically between a first inclined position and a second declined position, and each of said second crank arms depends in pendulum fashion from its associated first arm to swing horizontally between a first forwardly advanced position and a second rearwardly retracted position; said crank arms being powered by means of a first fluid cylinder interconnected between the hull and each of said first crank arms, and a second fluid cylinder interconnected between the two associated crank arms.
