US 376.475                          James G.  Greene

Patent US 322.428, to Philip Diehl, dated July 21, 1885, shows and describes a button-hole-cutting mechanism in which the button-holes are cut by a striking cutter, which is caused to descend quickly and forcibly by the movement of a handle attached to a rock shaft connected with the cutting-lever. Such a cutting mechanism has, however, been found to be objectionable for the reason that the shock or jar of the striking cutter or cutting lever loosens the screws and other parts of the button-hole-stitching machine to which the cutter is attached and thereby impairs the efficiency of the machine, besides being destructive to the knife. The object of my invention is to obviate the objections to the button-hole-cutting mechanism above referred to, this object being attained by providing the lever which carries the cutter or cutting-block with a hand-lever which is arranged to impinge beneath the lower end of the head at the forward part of the bracket arm of the sewing machine in such a manner that the cutting-lever may be forced downward by the operator to cut the button-holes by a gradual but powerful pressure.
