"This invention relates to an improvement in adjusting and setting plane-irons of carpenters' or bench-planes, of various descriptions, whereby these irons or blades can be adjusted and set at any desired pitch for removing very thin or very thick shavings, by simply turning a thumb-screw, which is applied to the plane-stock and blade in such manner as to give a greater or less bow or bead to the latter, according to the pitch required."
