L. Roherts d: Bros., for complainants. �E. P. Brown, for defendants. �LowELL, C. J. The original patent in this case, No. 177,- 296, dated May 9, 1876, describes a presser-foot for a sewing machine, intended for sewing stay-strips upon boots and shoes. These are narrow strips of leather sewed over that seam of the upper leather of the shoe which covers the heel or the instep, to protect the seam from the wear of the dress. The strip is folded or doubled over and sewed on each aide of the central ridge, or projection of an outward-turned seam, and bas a groove on each side, in which the stitches are to be laid. The presser-foot bas a groove to fit the projecting seam, and two ribs, or fiUets, as they are called in the original patent, to form the grooves. The hole for the needle is made in one of these ribs, One row of stitches is laid, and then the work is turned round and the stitches are laid along the other edge. Ail this is shortly, but sufficiently, set forth, There is described, besides, a "folding mouth," or tunnel, through which the plain strip is to be passed, in order to be folded or doubled over into the requisite shape. The claim is for "a sewing machine presser-foot, provided with means, substantially as described, for folding and channelling a seam- stay piece, such consisting of the fillets, e, e, and of the folder, composed of the tapering mouth, a, [and] the partition, d, ail being arranged with the guide-groove, h, and needle-hole, /, as set forth." �Soon after this patent was taken ont, it was found much Inore economical and convenient to fold and crease the stay- strip by a separate machine or operation, and then the plain- tiff obtained the re-issue, No. 7,55S, which is relied on in this ■case. ��� �
