A specialized router plane for hinges, the Stanley #171 door trim plane. The patent claims a reversible cutter and a spring to force that cutter down into contact with the surface being worked. In operation, the user would mark the end of the mortise with chisel cuts, set a depth for the router cutter, move the router in a back-and-forth motion from one end of the mortise to the other, flip the cutter 180 degrees, and repeat until the cutter bottomed out at its preset depth.
