The provenance of the document is an issue because it challenges the normal account of the development of tracked vehicles, in which the Holt Company purchased Hornsby's patent in 1913, allowing it to compete with the Best Company who had licensed Lombard's 1901 patent. The rival companies later merged into one, which ascended to its present pre-eminence as a colossus standing astride the globe under the name of Caterpillar (to provide a better logo for licensing for use on baseball caps and sturdy footware**).
It certainly appears from this patent as if the innovations behind the Holt company's success were in fact merely copies of prior art. I am personally of the opinion that a combination of drive sprockets and road wheels would have powered Ye Mechanismus for Providing Trans-Porte across Quags and Sloughs more effectively than an indentured scythe-wielding demon, but this is peripheral to the key mechanical insight of the articulated track.
Not covered by warranty.I am sure that the discovery has nothing to do with Another Kiwi's recent expedition in the Riddled time machine, nor with the fact that half the tea-room is currently cluttered up with shoes, baseball caps and other merchandise emblazoned with the distinctive Riddled logo.
** Cat Shoes are crafted by Michigan-based Wolverine World Wide, who also manufacture Hush Puppies -- which are totally hard-core footware and practical and NOTHING WOOFTERISH ABOUT THEM.
