Description:

An improvement to Swan's patent of 1868-06-09, "the object being the forming of the lip on bits or augers, known as the 'Cook bit,' to mechanically turn the lips up and over the dies upon which they are formed..."

The "Decisions of the Commissioner of Patents" for 1871 contains a decision handed down 1871-07-06 regarding interference between patent applications by William A. Ives and James Swan, both including claims for a die to form the lip of auger bits. The decision, in essence, was that Swan was the first to make a die described in his application, but Ives was the first to make a machine that used the die. If they had jointly applied for a patent then a broad claim could be awarded, but because they were separately filing, no such claim could be made by either regarding the die itself.
