Description:
A. B. Stroughton - patent attorney

In grinding machines for facing off pieces of steel, such, for instance, as knife sections for harvesting machines, or plane irons, or any other article requiring true and accurate sides and edges, I find that when constructed as at present in general use, the part of the steel or plate that comes first in contact with the stone is invariably rounded off and not a perfectly fiat surface. This is due, as I believe, to the play of the journals of the grinding-stone and the yielding of the bed, and probably of other parts of the machine without any compensation or provision for such play and yielding or counteracting influence. The object of my invention is to avoid this rounding off of the edge of the plate that first strikes or comes in contact with the grinding stone. And my invention consists in making the ways on which the bed moves, that holds and feeds up the article that is to be ground, concave, so that the bed may conform thereto under any undue pressure or sudden contact between the article and the stone.
