' NEEDLE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 397,619, dated February 12, 1889.

Application filed December 19, 1887. Serial No. 258,333. (Model) 1 o ton-sewin g machines, by which improvements,

if the needle in its reciprocating movements should be slightly out of center with respect to the eye of the button and strike the button alongside of the eye, it will glance into the I 5 eye and incidentally move the button into proper position.

In the use of button-sewing-machine needles as heretofore commonly constructed that is, needles gradually tapered to a point should the button in the button-holder be slightly out of center, so that the needle in its downward movement would strike the button at a point alongside of the eye, it would be driven or catch into the button and result in breaking the needle or button, or both, and, as this thing was liable to occur frequently, the loss attending such mishaps was of considerable consequence.

By my improvement the objections men- 0 tioned are overcome, such improvement consisting in a needle gradually tapered to nearly the end or point and then abruptly tapered to the point, so that if the needle should strike the button at a point alongside of the 3 5 eye the abrupt taper at the point will cause it to glance into the eye, and the stem or body of the needle as it passes down through the eye will incidentally center or move the button to proper position in the buttonholder, and the needle in its further recipro- 4o eating movements will pass directly through the eye.

My improvement will first be described in connection with the accompanying drawing, forminga part of this specification, and then pointed out in the claim, the said drawing representing a side View of my improved needle.

In constructing my improved needle I form the shank a and eye b as heretofore, but make the point or end designed to enter the I eye of the button and the fabric with what I term a glancing point that is, with the end gradually tapered to nearly the point, as from c to d, and then abruptly tapered to the point, as from d to 6.

By the construction described, should the needle strike the button alongside of the eye, the abrupt bevel d 6 will cause it to glance into the eye, and the passage of the shank a into or through the eye will have the effect of centering the button, so that the needle in its further reciprocating movements Will pass directly through the eye.

What I claim is A sewing-machine needle having an abruptly-tapered conical point, e d, and a less abruptly-tapered portion above said point and below the eye, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two sub scribing witnesses, this 10th day of December, A. D. 1887.
