UNITED STATES ALFRED S. WOODWARD, OF NEW YORK, N. Y.

IMPROVEMENT IN PRESSERSAND STITCH-DIVIDERS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 110,945, dated January 10, 1871.

To all whom it may concern: i

Be it known that I, ALFRED S. Woonwnnn, of the city, county, and State of New York, have invented an Improved Presser and Stitch- Divider for Boot and Shoe Sewing Machines, of which the following' is a speciication:

My invention relates to that class of devices connected with and forming part of a sewingmachine known as the presser, which is employed for holding the work to be sewed in position while the needle is entering the leather or material to be sewed 5 butpressers, as constructed heretofore, merely performed the oiice of holding the leather in position, as stated, while marking and dividing thestitches, to give the sewing a workmanlike and finished appearance, had to be done by hand, and not always with I accuracy, although much time, labor, and expense had been consumed in the operation.

To obviate the necessity for hand-labor 'in connection with the presser suggested to me the present invention, the nature of which consists in forming the foot of the presser concave or arched, so that it will press 011 the leather on both sides of the line of stitching, and at the same time permit the stitching to project a little above the surface of the sole of the boot or shoe, or other portions of the same to be sewed, and retain the natural round form after marking and dividing the stitches; and it also consists in attaching to the presser a marker or stitch-divider, for the purpose of marking and dividing the stitches with accuracy, giving' to the stitching of the boot or shoe a neat, accurate,'and workmanlike finish, as I will further explain by reference to the drawing, in which- Figure l is a side elevation of a presser,

showing the concave foot and stitch-divider attachment, Fig. 2, an elevation of opposite side, Fig. 3 a front elevation, Fig. 4 a top view, Fig. 5 an under-side view, and Fig. 6 a

rear view, of same, showing concave foot.

In the said drawing, A indicates the pressershaft, which is operated by the sewing-machine, and representedin dotted lines. B is the hub of the presser, 0,'the leg5-D, the concave heel; E, the foot, and F a set-screw for attaching the presser to the operatingshaft A.

The movements of the presser are reciprocating up and down, permitting the work to be fedalong at the proper time, as with ordinary pressers, while the concave heel D permits the stitching to retain its round form by passing under the concave heel, the presser, when down, bearing on both sides of the line of sewing.

H is the adjustable stitch-divider, attached to the leg C of the presser by set-screws I I,

which pass throughvslots K K in the stitchdivider, said divider being rectangular in shape, (see Figs. l and 2,) with its markingpoint L extending a little below the foot E of the presser.

The stitch-divider, being attached to the presser,` partakes of the movements of the presser, and the stitching being always in ad- Vance of the divider, as the presser is brought down on the work the divider strikes between the ends ofthe stitches, making a cross, crease, or finish, as set fort I claim- The presser D, having the concave recess G in the heel, and the adjustable stitch-divider H L secured thereto, substantially as and for the purposes described and specified.

In testimony whereof I have hereunto set my signature this 22d day of June, 187 0.

ALFRED S. VVOODWARD.
