The Gage Tool Co. (which was later bought by Stanley) did a different take on the "stay-set" plane where the chipbreaker was fixed to the lever cap with 2 screws (in slots for adjustment) that registered against a bar across the plane and the blade had a casting attached that sat in a deep groove in the end of the depth adjuster screw.

Because the chipbreaker is set to the body of the plane, rather than the blade, you'd only have to change it when your depth of cut changed.
