label: Description
content: This is a patent model of an iron planer, patented by George E. Brettell of Rochester, New York in March 1877.
label: Description
content: The invention was an improvement in iron-planers, in which a rod and crank mechanism within the cross-head acted on a pinion and shaft arrangement to lift the tool automatically at the end of each cut. This prevented the tool from dragging on the return stroke, while leaving the ordinary cross-slide and feed motions unaffected.
