OLIVER HOIVARD BLOOD, OF NEW YORK, N. Y.

NEEDLE.

SPECIFICATION forming part of Letters Patent No. 428,263, dated May 20, 1890.

Application filed March 25, 1890- Serial No. 345,191. (No model.)

To all whom, it may concern:

Be it known that I, OLIVER HOWARD BLOOD, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Needles, of which the following is a specification.

My invention relates to that class of needles which is threaded by a lateral movement of the thread.

The object of my present invention is to provide such needles at a reduced cost as compared with those heretofore made, to be threaded in the same way, and to afford greater facility for threading them.

\Vith these ends in view my invention consists in certain features of construction, as will be hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure l is a view of a needle in side elevation, showing an angular entrance to the eye. Fig. 2 is a similar View showing a portion of the entrance of curved form. Fig. 3 represents the eye at the point end of the needle, as in sewing-machine needles; and Fig. at represents a needle with the mouth of the entrance toward the observer and the thread .in position to be inserted.

The body of the needle is represented by the letter A. That portion of the entire circuitous passage-way which extends from the outside of the needle within the body of the same where the thread naturally is seated when the needle is in use I term the eye proper and have designated it by b. The course of the passage-way leading thereto is first downwardly and inwardly, as shown at c, and thence obliquely upward, either in a straight line, as shown at d, Fig. 1, or in a curved line, as shown in Fig. 2. The passage is also projected downwardly from the eye proper to its end, as shown at e in the several figures.

In using the terms downward and upward in the above description I have assumed the needle standing 011 its point. Downwardly, therefore, would indicate toward its point, an( upwardly .away from its point. It is to be observed that because of the circuitous passage a wider opening than heretofore may be left at the side of the needle without liability of the thread to slide out, and hence the needle may be more easily threaded.

To thread the needle, place the thread laterally across the body of the needle at or as near as may be to the mouth of the passage, and then, if need be, slip it along the needle to the mouth of the passage, exertinga slight strain upon it in a direction to draw it into the passage. It may all be accomplished in a moments time and without trouble. IVhen the needle is threaded as in use, the effect of the above-described passage-way is to direct the thread when slaekened either along the portion 6 to the closed end of the way or along the portion at to the angle or sharp turn f. In either case its further progress will be arrested and a subsequent strain upon the thread in a direction away from the point will reseat the thread in the eye proper. In fact, when the thread has from any cause dropped to the sharp angle f, its own weight or the strain on the side of the needle opposite the mouth of the passage-way will prevent any possibility of its backing out through the portion 0, and in order to get it out it is necessary to swing the thread or shift the needle in such a manner as to give the thread a downward, outward, and upward strain in close succession and on the side of the needle on which the mouth of the passage-way is located. The chances are so slight that such a combination of strains would ever unintentionally occur that the needle may be considsidered practically proof against unthreading.

What I claim as my invention, and desire to secure by Letters Patent, is-

A needle provided with on opening or passage-way for the thread, leading from the outside of the needle inwardly and toward the point of the needle, and thence away from the point of the needle in an oblique direction to the eye proper of the needle, the eye proper having an additional branch passage-way extending therefrom toward the point of the needle, substantially as set forth.

OLIVER IIOVYARD BLOOD.
