Description:

Adjusting the cutting depth of the cutting iron at either throat of a double end block plane. According to the History of Stanley Rule & Level Co. written by James Burdick c. 1930, this patent was never used, but John Walter cites it being used on the Stanley No. 131 double end blockplane. This patent is very similar to one issued to Justus Traut the same day 766473 which was used for the No. 131 and likely causes the confusion. These patents are redesigns to the earlier patent by Traut 645220 for cutter adjustments to standard blockplanes.
