Patent for a new and improved plow. This design consists in "the combination of the share having the keeper on the mold-board and the arm, the detachable point bearing against the outer side of the arm and having the tongue engaging the keeper, and the lever fulcrumed to the mold-board at a point between the keeper and landside, and having the short arm adapted to lap the joint between the point and mold-board and to engage the outer end of the tongue to lock the latter in the keeper" (lines 82-92).
