  • Patent number: 4567635
    Abstract: The invention to which this specification pertains represents a new design in cotter-pin extracting pliers, in that the toothed end of this invention is recessed down into the forked end, and the toothed end and forked end are flush with each other, the combination of which characteristics facilitate removal of deeply set pins from shafts and nuts. Another improvement is found in the fact that the pin to be removed is surrounded by the forked end of this invention to prevent slippage. We believe that the extended and upwardly curved upper jaw, unique to our invention, will make possible a tool which will better perform the job of extracting cotter-pins; at the same time, the compact design and the placement of the pivot point make possible a tool requiring a very small amount of space in which to perate, because compression of the handles is the only movement required.
