Description:
The commissioner's report on the application for the extension of this patent says, "The fourth claim of the patent reads as follows: 'I claim in a wood-splitting machine two separate knives, at an angle, or diagonally to each other, and each extending across the feeding-floor, so as to split up the wood in the manner specified.' This claim is fully anticipated by English patent No. 5169, granted to one Weatherly November 14, 1825, the only difference being that Williams uses only one pair of knives, arranged diagonally to each other, and reaching entirely across the feeding-floor; while Weatherly uses two separate pairs of knives, or two separate feeding-floors, each pair of knives constructed in the same manner as Williams's and reaching entirely across its own feeding-floor, and so arranged up a single shaft as to have one pair ascending while the other is descending. I think the first, second, and third claims of Williams's patent embrace novel and useful improvements, and that he has shown, though not in as lucid a manner as he ought to have done, that after using due diligence he has not yet received adequate remuneration for his time and the value of his invention. Therefore, upon filing a disclaimer to the fourth claim, the patent will be extended."
