to this particular use, and that the terms vamp, by a pin 47. For turning the plate 41 about its quarter and. piping. are used herein and in. pivot, the plate'3-3 rotatablycar'ries an eccentric pin 49, opposite sides of which latter are contacted by the side walls of a notch 51 formed in the end of the plate 41. As best illustrated in Figs. 1, 4 and 6, the eccentric 49 is provided with an extension 53 rotatably received in a perforation 55 in the arm 35, the end of the pin 53 being provided with a head 57 for preventing its removal from the ,perforation. Conveniently the eccentric is provided with a slot 59 for receiving the end of a screw-driver for adjusting the eccentric, the latter being held in adjusted position by the frictional fit of the parts.

Referring to Figs. 9, 10 and 11, the end of the arm 35 adjacent the needle is beveled, as i ndicated at 61, on its under side to approximately a knife edge, the beveled portion cutting entirely through the bottom wall of the groove 39 adjacent the end of the arm to provide aipair of projections 63 leading to adjacent the needle 37 and serving to guide the piping thereto. The upper'side of the plate 41 adjacent the needle is beveled, as indicated at 65, atorie side of its top surface to 'a knife edge indicated at 67. This construction provides a minimum thickness of metal between the layers of the work being sewed, and facilitates proper holding of the work when I operated upon by the presser-feet hereinafter described. 1

Although the invention is applicable to various types of sewing machines, that herein indicated comprises a needle bar 69 and a'pair of presserfoot bars 71, 73, below whichis'a work feed 75. The mechanism of the sewingmachine', which it is believed unnecessary to describe, and which, for example, may be the well known'Singer 108 W. 1, operates to cause the needle bar and presser-footbar' 71 tobe reciprocated and walked with the feed 75 so as to advance the work the distance of a stitch for each reciprocation of the needle, the presser-foot bar 73' being of the plain reciprocating type, acting to hold the work'except when the needle bar and presser-foot bar.

71"are.walked. I v

As shown,the walking presser-foot 'lfi on the endof the bar 71 has a lower work engaging portion 77 provided at its front with a groove 79 the walls of which are closely adjacent to the needle. The presser-foot 81 on the presser-foot bar 73, as illustrated, has a portion 83 in front of the needle and a side portion 85 which contacts with the side of the lower portion 77 of the presserfoot 76 so as better to maintain the two presserfeet in operative relation with each other and the needle. The portion 83 of the reciprocating presser-foot 8l-is beveled at its front and sides to clear the ends of the projections 63 on the ends of the arm 35 and to contact with the work in the space between these projections, the contact area being approximately indicated by the dotted line surface area87 in Fig. 12, which latter shows a diagrammatic arrangement of the parts. The remaining bottom area of the presser-foot 81 is so formed as to clear the work or at least to contact with it with a minimum of pressure. The contact area of the walking presserfoot 76 carried by the presser bar '71 is indicated in Fig.12 approximately by the dotted line surface area 91. V V r I As a result of the above described construction, it will be observed that the work is held at both sides of the needle when the latter penetrates the work, and is heldby the portion'l? of the walking presser-foot 76 during the feeding op eration. It will be further observed that herein the piping is guided approximately all the way.

to the needle, and that the pin 45 for gauging the vamp edge, being located directly opposite the needle, permits the operator readily to swing the work where the edge of the vamp is an irregular line as commonly found in shoes.

In practice, the two presser-feet and needle may be raised by the usual lever operated mechanism commonly provided for, this purpose in sewing machines, which permits the end of arm 35 adjacent the needle to be lifted slightly to enable the quarter to be inserted under the arm and the vamp to be placed on top of the arm, after which the presser-feet may be released to conby use of the screw-threaded pins 27, which are effective to adjust the parts transversely of the sewing machine bed as viewed in Fig. 1, and also -by sliding the plate 33 in the groove 31 for adjusting the parts longitudinally of said bed, while the distance the piping projects beyond the vamp edge may be adjusted by use of the eccentric 49. For the above purpose the part 33 may be ad'- justably secured to the part 29 in any convenient manner, as for example byproviding the part 33 with slots 93 through which extend. headed clamping screws 95 threadedv into the part 29.

.It will be observed that. the present invention provides for application of the attachment or accessory without change in the sewing machine, for thereason that the base 13 is substituted for the usual bobbin plate, and the two presser-feet of course attached to the presser bars in the ordinary manner so as to be interchangeable with other presser-feet used'with the sewing machine. This enables the attachment to be sold as an article of commerce to shoe and leather manufacturers without it being necessary for the latter to form attaching holes in the sewing machine parts or to send the sewing machine to a machine shop or the like for this purpose.

It will be understood that wide deviations may be made from the embodiment of the invention herein described without, departing from the spirit of the invention.
