Other than this one article, I have nothing else on this Walking Wagon.
Fort Wayne Sentinel 14 Sept 1887 p1
A WALKING WAGON
This Ingenious Contrivance Exhibited to the People of Fort Wayne.
A young man named Browns [Brossins?], from Abolt station, has a novel contrivance on exhibition in this city. It is a "walking wagon," and M Broatios is a former Fort Wayne boy much interest is manifested in his work.
Some of the readers of The Sentinel will perhaps remember of a similar machine being in tbe city eight years ago, [1887-8=1879] then improperly called "mad wagon." [mud wagon?]
The inventor of this road machine has ever since been patiently applying his mind to the completion of his patent and has now completed a machine which is in every sense a walking machine. Any man practically understanding machinery, on seeing this machine will at once say that this is the only truck so far invented on which a steam engine can be succesfully mounted for steam plowing.
This machine is constructed in two parts, or sides, corresponding to the sides of an ordinary wagon, but instead of having wheels running on the ground, each side is composed of an elliptical track and a series of traveling rests or feet rigidly fastened to an endless belt. The track is so constructed that the rests or feet step down as a horse would, and after the track has passed over them, raise in the same way. This makes the machine a great curiosity.
One great difficulty in the first machine was the turning. This has become so thoroughly overcome that it can be turned in the length of itself.
The merits of this machine will probably be shown to the public at the Fort Wayne fair.
