All those kinds of feed motion (applied to sewing machines) which consist in the motion of an independent foot or feed pad, are apt to be irregular in their action. The inventor of the arrangement illustratedby the accompanying engraving has devised a plan to obviate this difficulty. A is the end through which the needle shaft moves up and down, having projecting from it a piece, B, to which is hinged the piece, C, by the screw, c. The screw, D, fastens E, and to it is hinged by the screw, f, the foot, F ; this is kept on the cloth by the pressure of the spring, e. This foot has an independent mo- tion communicated to it from the driving wheel through the parts we have described; it is serrated on its lower side to grip the cloth. I is the portion that lays on the cloth, and through it is inserted the supplementary foot, J, (seen separate in Fig. 2), which is kept in place by the springs, j and i, and by their means it is always able to maintain a hold on the cloth, and ensure the regularity of the feed motion. The needle, H, attached to the piece, G, passes through this supplementary foot, which has in it a slot, to allow the same. It is especially applicable to the cheap machines, and was patented November 3, 1857. Further information may be obtained from C. H. Andrus, Collins' Hotel, New York.
