Samuel Blatchford, Thompson v. Hall — Opinion of the Court
“ In that invention either of the two hand-levers may be turned on its pivot without turning the other, and the tool-body formed by the face or covering plates is permitted to vibrate, or turns more or less, with relation to the handles, and the central space between the cutting faces of the jaw-levers, when the pliers are taken in the hand to be used, drops more or less out of line with the central line of the handles, making, as it were, a loose joint midway between the ends of the pliers. ”
