Application July 12, 1949, Serial No. 104,293

2 Claims.

This invention relates to new and useful improvements in a combined stitch removing and sewing needle, and it is among the objects thereof to provide a sewing needle which may be mounted in a needle bar in two positions and which shall have a cutting edge for cutting stitches in one position, and an eye for sewing thread for sewing cloth in its other position.

The invention will become more apparent from a consideration of the accompanying drawing, constituting a part hereof, in which like reference characters designate like parts, and in which:

Fig. l is a front elevational View of a combined stitch cutting and sewing needle embodying the principles of this invention;

Fig. 2 a similar view thereof with the needle turned 90;

Fig. 3 a cross sectional view of the needle shank taken along the line 3-3, Fig. 2; and

Fig. 4 a front elevational view of a needle bar and needle.

In the drawing, numeral 1 designates the shaft of a needle having a working body portion 2 and a shank 3. The shank is shown in Fig. 3 having flat faces 4 and 5 and a rounded portion 6. The working body portion of the needle is wedge shaped as shown in Fig. 2 and is pointed at I as shown in Fig. l, the point having a flat edge 8 at the bottom as shown in Fig. 2. An eye 9 of slightly oblong shape is provided above the point I for a thread.

The needle is mounted in a needle bar I!) having a groove H with a flat bottom face l2. The needle is secured by a band l3 that is drawn up by a-screw [4. When the flat faces 4 and 5 are placed against the face [2 of the groove, the needle will be in either of the two positions shown in Figs. 1 and 2. A conventional needle bar having a round or flat socket for the needle shank may be employed, in which case the end of the screw I4 would secure the needle against turning by engaging either of the flat faces 4 and 5 of the shank as shown in Fig. 3.

The needle is wedge shaped as shown in Fig. 2 to provide clearance on the upward stroke of the needle to prevent the cloth from adhering. Also the working body 2 of the needle is rounded at its edges I5, Fig. 2, to prevent adherence of the cloth to the needle when operating. The face 8 of the needle is relatively narrow but of suflicient width to cut stitches of a seam when the needle is placed in the machine in the manner shown in Fig. 2, the seam being fed underneath 2 the needle in the same manner as in conventional sewing practice. In this manner most all or a sufficient number of the stitches are cut when passing through the machine to readily separate the same, after which the loose threads may be readily removed.

The needle may be used for sewing in the conventional manner by turning it in the needle bar to the position shown in Fig. 1. It is threaded through the eye 9 and the sewing is done in the usual manner.

The needle is designed to avoid damaging the fabric for either the stitch cutting or sewing operations. The working edge 8 of the needle is reduced to a minimum and yet of a sufficient width to cut the stitches of the seam passed therebeneath. The Working body 2 is tapered to provide clearance on the upward stroke and is of substantial length to prevent catching material when reversing. The body portion is rounded to lessen wear on the material while the needle is passing through the fabric.

I have found that by the use of a stitch removing needle of the above described character, the labor of removing stitches is greatly reduced and becomes as simple as sewing itself. Any experienced seamstress can remove stitches by the use of the needle without causing any appreciable damage to the material.

Although one embodiment of the invention has been herein illustrated and described, it will be evident to those skilled in the art that various modifications may be made in the details of construction without departing from the principles herein set forth.

I claim:

1. A combined stitch cutting and sewing needle consisting of a shaft having a shank portion and a working body portion, the body portion being of substantially wedge shape terminating in a flat cutting edge and having an eye above the cutting edge transversely of the flat faces thereof, said shank portion being shaped to provide a clamping surface for aligning the cutting edge of the needle in the plane of movement of the material for sewing and having another clamping surface at right angles to said first-named clamping surface for aligning the cutting edg of the needle transversely to the line of movement of the material in its normal passage through a sewing machine.

2. A combined stitch removing and sewing needle comprising a needle shaft having a shank at one end and a working body portion at its other end, the working body portion being of 3 substantially the Width of the shaft and tapering to form a flat end, said body portion being sharpened at the flat end to form a flat cutting edge and having an eye extending transversely of the flat faces thereof above the cutting edge, said shank portion having two flat faces at right angles for clamping engagement with a screw on a needle bar, whereby th needle may be secured in the bar with either the cutting edge in alignment with the direction of 10 Number movement of the material moving underneath the needle, or with th cutting edge disposed transversely of the line of movement of the material to respectively sew or cut stitches in the material.
