Specification of Letters Patent.

Patented Feb. 13, 191% Application filed January 21, 1910. Serial No. 539,229. I

To all whom it may concern:

Be it known that I, ANGUS CARSON, a

citizen of the United States, residing at Tio.

and useful Improvements in Sewing-Ma-- chine Needles; and I do declare the following to be a full, clear, and exact description of the invention, such as will'enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specifi- 'cation.

This invention relates to a sewing machine needle and has for its object to provide a device of this class which can be quickly and easily threaded and which is so constructed and arranged that it is employed as an ordinary needle, the threading attachment in no way interfering with the sewing action of the needle.

with this object in view this invention consists in the novel construction of the needle, and in the novel construction of the threading attachment, and the invention also consists in providing the eye nearer to one side of the needle or eccentrically therein in order to provide additional strength at this point. v

Referring to the accompanying drawing: Figure 1 is an elevation of a needle constructed in accordance with this invention. Fig. 2 is an elevation from the left side of Fig. 1. Fig. 8 is an elevation showing thread being led to the eye. Fig. 4 is an elevation showing a needle threaded, and Fig. 5 is an elevation of a threading attachment or wire. Fig. 6 is a transverse section through the shank of the needle and through the wire at a point above the threading loop.

Like numerals of reference indicate the same parts throughout the several figures in which:

1 indicates the needle which comprises the shank 2, eye 3 and point 4.

As will appear from the drawing the shank of the needle is provided longitudinally with a groove 5 of sufiicient depth to accommodate the threading attachment or wire 6 in such manner that the entire wire with the exception of the loop 7 lies within the surface of the needle. By means of this construction the threading attachment presents no projections nor protuberances which would interfere in the slightest degree with the sewing action of the needle. I

As will appear from the drawing, the eye 3 is located eccentrically in the needlein such manner that the needle stock at the point '8 to one side of the eye 3 is considerably thicker than on the opposite side of the eye, thus materially increasing the strength of the needle at this point. This construction is particularly advantageous in view of the fact that there is an opening 9 from one side of the needle into the eye through which the thread 10 is introduced by means of the wire 6.

In order to firmly anchor the wire 6 in the needle so as to prevent its displacement while the needle is in operation, the lower portion of the wire 6 is bent inwardly at 11 at substantially right angles to the needle and embedded therein under the eye, while the upper end of the shank is provided with-a transverse groove 12 and the upper portion of the wire 6 is bent at 13 to extend parallel to the needle a portion of the wire so bent lying in said groove. In order to prevent the wire 6 rotating and to anchor the upper portion of the wire firmly to the needle the extreme upper end of the wire 6 is bent downwardly parallel with the needle and lies in a short groove 14 at the upper end of the shank. The loop 7 of the wire 6 imparts a slight spring action to the wire which tends to draw the ends'of the wire together thus securely holding the bent ends of the wire in their proper position and pre venting accidental displacement of the attachment.

Having thus fully described this invention its operation is as follows: The wire and attachment 6 being applied to the needle as shown, the needle is threaded by inserting the thread 10 through the loop 7, and as the thread is drawn down the shank the wire 6 is forced out of its groove until the thread reaches the eye of the needle. At this point it passes through the opening in the side of the needle and into the eye, which allows the wire 6 to spring back into its groove which action closes up the opening and holds the thread securely in the eye. The needle is then employed in the usual manner and is as strong and durable as the ordinary needle, as the wire 6 is at all times protected and cannot be injured by continued usage.

Having thus fully described this invention, what I claim as new and desire to secure by Letters Patent of the United States 1s A needle including a shank having a longitudinal groove therein, an eye and a point, 5 and a resilient member received by said groove and having a right angled lower end terminal and an upper end bend with a portion parallel with the shank body, said shank lateral opening receiving said right angled lower end terminal and said upper end short groove receiving the parallel portion of the upper end bend of said resilient member.

In testimony whereof, I afiix my signature, in presence of two witnesses.


also having a lateral opening communicating W'itnesses: 10 with sand eye, and a short groove 1n its up- WALLACE CHADMAN,

per end to receive said reslllent member, said C. M. ARNER.
