IMPROVEMENT IN SEWING-MACHINE NEEDLES.

Specification forming part of Letters Patent No. 37,585, dated February 3, 1863.

To all whom it may concern:

Be it known that I, JOHN MADDEN, of Youngstown, in the county of Mahoning and State of Ohio, have invented new and useful lmprovements in Sewing-Machine Needles; and I do hereby declare that the following is a fulland complete description of the construction and operation of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figures 1, 2, and 3 are difterentviews of sewing-machines, and Figs. 4 and 5 views of the needle.

The nature of my improvement relates to the structure of the needle. Therefore in the following description I shall confine myself to this particular feature.

I first take a bar of steel and lit a shank,A, into the needle-bar B, where, when the needle is finished. itis held by a set-screw, O. The

shaft D of the needle is then reduced to its proper form and size andpointed and polished. 1 then, with asmall buir' which has a rapidmotion on a shaft or spindle, cut a channel or groove, E, along'the shaft D, leaving a short space-sayone-twentieth of an inchas seen at F, withouta groovg, resuming the groove again toward the point. I then, with a fine drill, extend the channel or groove E through the solid portion F, leaving the surface F extending from one lip of the groove to the other, making the channel or groove continue as seen in section, Fig. 5. The thread is passed bchind the bar F from the groove above to the groove below. y

I am aware that tubular needles have been made and used but there are mechanical difliculties in the way of making-namely, drilling so small a hole for, the distance required; and, besides, it is very difiicult to pass athread through so fine a tube. My improvement 0bviates both these difficulties, while the needle manufactured after my improved plan is more durable and stronger than the eye-pointed needle; and a still further advantage is found in the readiness with which the ioop is formed, consequent upon the uniform position assumed by the thread on withdrawing the needle from the cloth.

What I claim as my improvement, and desire to secure by Letters Pateut,'is-

As a new article of manufacture, the sewing-machine needle constructed as herein set forth.
