SEWlNGiVlACI-HN E ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 586,872, dated July 20, 1897.

Application tiled June 17, 1896.

Be ithnown that I, WILLIAM ALBERT ScoTT, of Newcastle, in the county of Garfield and State of Colorado, have invented new and useful Improvements in Sewing-Machine Attachments, of which the following is a full, clear, and exact description.

This invention relates to devices designed to be attached to the presser-t`oot of a sewingmachine for folding in the edge of the material prior to stitching the same; and the object is to provide a single vdevice which may be used for a number of purposes where heretofore it has been necessary to employ a de vice for each width of hem or tuck.

My device is adapted for all widths of hemming and all sizes of tucking.

The device is also adapted for stitching` bias or straight strips onto the surface of the material.

I will describe an attachment embodying my invention and then point out the novel features in the appended claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters ot' reference indicate corresponding.;- parts in all the views.

Figure l is a plan view of an attachment embodying my invention and showing the same as arranged for turning the edge of a material to form a narrow hem. Fig. 2 is an end elevation thereof. Fig. 3 is an end elevation showing the device as employed for turning in the edge of a bias or straight strip preparatory to stitching its edge to the material. Fig. 4f is a perspective view of the edgeturning device. Fig. 5 is a section on the line 5 5 of Fig. 4. Fig. t5 is a plan view of the device, showing it as adapted for wide hexns. Fig. 7 is an end elevation thereof. Fig. S is a plan view showing the device as used as a tucher, and Fig. 9 is an end view thereof.

The turning device comprises a substantially cone-shaped tube l, having its smaller end extended toward the needle of the sewing-machine and having at one side a longitudinal opening' from the lower wall of which a partition extends transversely of the tube and from one end tothe other thereof. This partition is located about midway between the upper and lowersidcs of the tube, and at its forward end is provided with a Serial No. 595,853. (No model.)

downwardly-curved lip l, which is designed to turn in the edge of the goods. There is a space between this lip 4 and the bottom wall ot the tube sui'iiciently wide for the passage of the goods operated upon.

The turning devices are attached t-o an arm 5, which at its opposite end has rotary connection with a hand adjusting-screw 6, the said adjusting-screw passing' transversely through a tapped hole in the shank portion of the presser-foot 7.

The device just described and particularly illustrated in Figs. l and 2 is arranged for narrow tucking, but may be adjusted by means of the screw for various widths.

In Fig. 2 l have shown a piece of cloth Sas engaged in the turningdevice, and I have shown in Fig. the edge of the strip 9 as engaged in the turning device preparatory to stitching the edge of said strip to a body of cloth.

In Figs. 6 and 7 I have shown a device for supporting the material when it is desired to form a very wide hem thereon. This supporting device consists of an arm lO, movable transversely of the turning device l. As here shown, it is movable between guide-pieces ll, secured to the under side of the turning device. The arm l0 may be friction-tight in said guide-pieces. The end of the arm lO is provided with transverselyextended fingers 12, and it has its end turned upward and curved slightly rearward, as indicated at 13.

In using this device the cloth 14 is passed beneath the arm 10, carried around the end 13, and then its edge is inserted in the turning device, as plainly indicated in Fig. 7. It may be here stated that by making the turning device conical, as shown, theinturned portion 14 of the material will be decreased in width as it emerges from the smaller end of the device and before reaching the needle.

In Figs. S and 9 I have shown a hem-marking device in connection with the edge-turning device. This hem-marking device cornprises an upper arm l5, which extends across the upper side of the turning device, and a lower arm 1G, which extends across the lower side of the turning device. The upper member`l is provided with a longitudinal slot 17, through which a set-screw 1S passes to an engagement with the turning device or with the IOO arm extended therefrom. At one side of the slot 17 the upper member 15 is provided with graduating-marks, by means of which the position desired for the marker may be ascertained.

The free end of the lower member 16 is provided with a notched block 19, and the free end of the upper member 15 is provided with a wedge-shaped block 20, adapted to move into the slot of the block 19 and press the goods therein, forming a line or crease indieating the place where the hem is to be turned. Extended rearward from the free end of the upper section 15 is an arm 21, the end of which is adapted to be engaged by the under side of the needle-bar 22 on its downward movement, and by this Contact the \VILLIAM ALBERT SCOTT.
