,chine while the needle is being withdrawn therefrom and which is movable with the needle, so that the fabric can be easily shifted into a desired position while the needle is raised.

The invention consists of a foot formed at one end of a spring-arm having an integral coil adapted to surround the upper portion of the needle, and a retaining-arm extends upward from the coil for engaging the setscrew which is ordinarily employed for holding the needle within the needle-bar.

The invention also consists of certain other novel features of construction and combina tions of parts, which will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings, Figure 1 is a perspective view of the device, and Fig. 2 is a detail view of a portion of a modified form.

Referring to the figures by numerals of reference, 1 is an arm formed, preferably, of spring-wire and terminating at one end in a coil 2, from which extends a loop 3, constituting a foot, the end of the wire being hooked into the coil, (shown at 4,) so as to hold the loop in shape. The other end of the arm 1 has another coil 5, which is positioned above the loop and terminates in an extension 6, which extends laterally from the coil and is curled, as shown at 7, and merges into an angular arm 8. The needle 9 of a sewingmachine is adapted to be inserted through the coil 5, and the parts 1 and 3 are so disposed in relation to each other that when the coil 5 bears against the end of the needle-bar 10 the loop 3 will assume a substantially and close to the eye thereof.

horizontal position around the needle above The angular arm 8 engages the set-screw 11, extending from the needle-bar and which is ordinarily employed for securing the needle in position. With the attachment disposed in this manner the fabric to be worked can be placed under the foot 3 and the needle 9, and by operating the machine the needle will reciprocate vertically, as in the ordinary manner, and each time the bar 10 moves downward it will press the foot 3 against the fabric and clamp it thereagainst, because such downward movement will tension the coil 2.

The foot 3 constitutes an excellent presserfoot for holding the fabric while the needle is passing downward into the fabric and While it-is being withdrawn therefrom, and as the foot rises with the needle after the same has 'been Withdrawn from the fabric said fabric can obviously be readily moved into a new position. As the entire device is formed in a single length of spring-wire, it can be made at slight cost, is very simple and durable, and cannot get out of order.

If desired, the end of the foot may be extended parallel with the arm 1 and secured thereto adjacent the coil 5, thereby reinforcing said arm. This construction has been fully illustrated in Fig. 2, wherein the end 12 of the foot is shown extended along and secured to the arm 1.

What is claimed is 1. An attachment for sewing machines formed of a single length of spring metal and comprising an elongated loop constituting a foot and capable of movement laterally and longitudinally independently of a needle in position therein, a coil at one end of the loop, a bowed arm extending from the coil and overhanging the loop, a needle-receiving coil at one end of the arm and disposed substantially at right angles to the loop, and a resilient needle bar engaging arm extending from the needle-receiving coil.

2. An attachment for sewing-machines formed in a single length of spring metal and comprising an elongated loop constituting a foot and capable of movement laterally and longitudinally independently of a needle in position therein, a coil at one end of the loop,

a bowed arm extending from the coil and In testimony that I claim the foregoing as overhanging the loop, said arm being reinmy own I have hereto affixed mysignature forced throughout its length, a needle-receiv in the presence of two Witnesses.
