The extended groove a sewing-machines it is frequently necessary to holds the braid from moving sidewise until it turn the goods or move them so that the braid 10o may be attached in various designs. The presser foot, by resting constantly on the goods, prevents the goods from being moved with facility for the purpose referred to.

To obviate the objection I employ the following means:

F is a presser-foot, and F foot bar.

G is an arm or lifter, the lower end of which is fitted nlovably upon the square portion of the bar F, and the upper end of which is curved or bent to project horizontally away from the said bar, as shown.

H is a setserew passing through the lower part of the lifter G, and having its inner end or point in contact with the bar F, thereby securing the part G adjustably to the bar F, or so that it may be moved up and down thereon and secured in any position in which it maybe set.

I is a slot in the faceplate. This slot is lo cated in the back of the face-plate, and the screw H passes through the slot I, as shown. By this means the exposed end of the screw H is conveniently accessible, and may be made tighter loose and raised or lowered for the purpose of adjusting the lifter Gvertically 011 the presser-foot bar.

J is the end disk of the horizontal shaft of the machine, and d is a small pin or stud projecting therefrom. This pin is arranged directly opposite the roller K, which vibrates the needle as the said shaft is rotated, and the upper or horizontal part of the lifter G is ar ranged, as shown, to be struck and raised by the pin (1 each time said shaft is once rotated. By this means the presscr-foot will be raised from the goods while the needle is in the goods, and the latter may then be turned on the needle as a pivot, thereby admitting of the goods being turned with facility, so that the braid may be evenly stitched thereto in various patterns or designs.

It will be perceived that the lifter G may is the presserbe raised or adjusted either so as not to be struck by the pin d when no braiding is to be done, or that it may be so adjusted that its movement will be greater or less, as may be desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an under-braider, a throat-plate constructed with a braid-passage and a needlehole, said braidpassage extending beyond said needle-hole, substantially as herein described, for the purpose set forth.

2. The combination, in an under-braider, of a throat-plate, A, having a groove, a, in its upper side to form the terminal end of the braidpassage, with a needle-hole, 7), within said groove, said groove extending beyond the needle-hole, and a cover or tongue, E, overlying the braid within said groove, substantially as herein specified.

8. The combination of the throat-plate A, having in its upper side the braid-groove a, and the braid-pressing spring B, having therein a needle-hole, and arranged substantially as shown and described with relation to the needle, for the purposes specified.

4. The combination, with the braid-grooves of an nnder-braider, of a spring adapted and arranged to press the braid yieldingly on its passage to the needle, and the tongue E, having in its free or outer end a bevel or arch, c, substantially as and for the purposes specified.

5. The combination, in an under-braider, of the grooved throat-plate A, the spring B, the grooved shuttle-race slide D, and the tongue E, all arranged substantially as shown and described with relation to each other, for the purposes set forth.
