SEWING-MACHINE NEEDLE.

SPECIFICATION forming part of Letters Patent No. 286,014, dated October 2, 1883. Application filed January 3, 1883. (N o-model.)

To aZZ whom it may concern.-

Be it known that HARRY IVIANN JENKINS, of San Francisco, in the county of San Francisco, and State of California, now deceased, did invent a new and useful Sewing-Machine Needle, of which the following is a specificatiou.

This invention relates to an improvement in open-eyed needles of that class employed in sewing-machines.

To enable others skilled in the art or science to which this invention more nearly appertains to make and use the same, reference is had to the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a top view. Fig. 2 is a bottom view, and Fig. 8 is a side view.

Similar letters refer to similar parts throughout the several views.

In the manufacture of this needle an elongated groove, a, is made in one side of the needle-blank, extending from near the heel to the eye, in which it terminates. A threadgroove, 2), is made in the other side of the blank, nearly opposite the point or eye end of the groove a the grooves a and 6 being thus so arranged as to enter into the formation of the needle-eye. The needle-blank on one side of the eye, or that side where the edges of the grooves a and b more nearly approach each other, is cut away, so as to form an inclined slit, 0, by which the grooves a and b are laterally connected, the needle-eye being thus formed with an opening on one side. WVhen the needle is threaded by passing the thread through the inclined slit 0, the formation of the latter is such as to diminish the liability of the thread becoming'accidentally displaced, so as to leave the needle unthreaded. 1 The swell or protuberance at the point of the'needle upon that side of the grooves opposite the open eye is a little greater than the diameter of the blank above the eye, so that the upper lip, d, of the open eye will not catch upon the material through which the needle is passing, 5 and it will also cause a little larger perforation to be made in the fabric, so that in operation the thread will not be crowded or abraded. It will thus be seen that the preponderance of metal is at that point or back of that point where the slot is made to form the open eye, and that it will be no weaker at that point than if the eye were intact, as in the ordinary construetion,where the eye is intact, since the loss of metal is partly compensated for by enlarging the blank at that point back of the open eye.

By this construction of needles the liability of fracture or breaking at the eye is prevented, and close and thick fabrics or ma- 6o terial can be sewed-such, for instance, as

heavy cottons, woolens, and even sole-leather; and by the peculiar construction of the threadgrooves the threadis less liable to be out in the thrust as the needle plays up and down in the fabric.

Having thus described the invention of HARRY MANN J ENK Ns, I do not claim, broadly, an open-eyed needle; but

Nhat I'do claim as his invention is An open-eyed sewing-machine needle having a longitudinal groove, a, extending from near the heel of the needle-blank and terminating in the eye, a thread-groove, I), nearly opposite the point or eye end of the groove 64, 7 5 said grooves entering into the formation of the eye, an inclined slit, 0, connecting the grooves a b on one side of the eye, and a swell or enlargement of the needle-blank on the op posite side of said eye, substantially as de scribed.
