HEMSTITCHING ATTACHMENT FOR SEWING-MACHINES,

SPECIFICATION forming part of Letters Patent No. 288,036, dated November 6, 1883.

Application filed March 5, 1883. (No model.)

.ToaZZ whom, it may concern 4 Be it known that 1, WILLIAM E. DONNELLY, of Cleveland, in the county of Ouyahoga and, State of Ohio, have invented certain new and useful Improvements in Hemstitching Attachments for Sewing Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to a device, adapted to be attached to a sewing-machine, whereby an open seam may be formed; and it consists in the parts and combination of parts, as will be hereinafter fully set forth and claimed.

In the drawings, Figure 1 is a view in perspective of my device, showing the same se-.

cured to a sewing-machine. Fig. 2 is a view in perspective, looking at the underside of my presser-foot; and Fig. 3 is a view in perspective of the guide'plate.

A represents a presser bar of a sewing-machine, to which is secured, in any of the usual methods, the presser-foot B. The horizontal portion of the presser-foot B is provided with a groove, a, of sufficient width to allow of the passage of the upper piece of goods which is to be operated upon, thus forming the hori zont-al portion into two plates, 11 and c. 7

d is a needle-hole, which extends vertically through the upper and lower plates, 6 and c. Extending from the needle-hole d in the lower plate, 0,.is formed a slot, 6, which passes from the said needlehole d backward to the rear end or heel of the presserfoot. (See Fig. 2.)

O and D are two Ushaped arms, which connect the upper and lower plates, 1) and 0. These arms 0 and D are so located as to leave 40 a space, E, between them for the passage of an arm, E, of the guide plate F.

F is a guide-plate, which is adjustably secured to the base-plate of a sewing-machine by means of a screw, F, or in any other suitable manner. This guide-plate F is so slotcr -bar A, and the guide-plate F being adjusted to the desired distance from the needlehole, the edges of the goods to be sewed are brought up to the guide-plate F. One edge is placed under the platec and the other edge over 0, and between it and the plate I), thus making the plate 0 act as a gage, whereby the distance or width of the open seam is determined. After the goods have been adjusted, the machine is set in operation, and the needle passes throughboth edges, and they are united by long stitches, said stitches being at the proper distance from the edge of the goods. Thus, when the two pieces are held apart, the edges will just meet and will both occupy a position in the same plane when laid flat.

Carriage -bow and whip covering may be sewed with my device, so that when stretched upon the bow or whip-stock the two edges will just meet and the seam willbe level with the exterior of the leather all around.

"What I claim is 1. In a sewing machine presser-foot, the combination of the horizontal plates 1) and 0, having a space between them for the passage of the upper piece of goods to be sewed, and connected by arms, between which is left a space to receive an arm of a guide-piece, substantially as set forth.

2. In a sewing -machine presser foot, the combination, with the upper plate, 1), pro vided with a needle-hole, of the lower plate, 0, provided with a slot, 0, said plates being connected by arms O D, between which a space is formed to receive an arm of a guide'piece, substantially as set forth.

3. The combination,with a presser-foot having an upper and a lower plate connected by suitable arms, of a guide-piece provided with a central arm adapted to enter a space between the arms of said plates, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this 24th day of February, 1883.

WILLIAM E. DONNELLY.
