Specification of Letters Patent. V

Patented Sept. 16, 1913.

Application filed October 14, 1912. Serial No. 725,555.

I To all whom it may concern .Be it known that I, WI'IMER J. Knnnro, a citizen of the United States, resid1ng at Lancaster, in the county of Lancaster and .State of Pennsylvania, have invented certain new and useful Improvements in Sewing-Needles, of which the following is a specification.

This invention relates to improvements in sewing needles, but more articularly to needles used on sewing mac ines.

The object in the present invention is'to provide a sewing machine needle into which the thread may be inserted with case while it is in the machine.

The invention consists of a hollow, tubular body of uniformly circular cross-section, formed by xturning a fiat oblong sheet of metal into spiral form, said sheet of metal being beveled along its longitudinal edges to form a spiral thread engaging slot in the finished body, which slot terminates in an eye near the reduced end of the needle, and having suitable thread engaging means at the upper or entrance end of the slot and suitable guard means at the lower or eye end, for retaining the thread after ithas been inserted.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawing, in which:--

Figure 1 shows a plan View of the sheet of metal from which the needle is to be meral 5. In forming formed. Fig. 2 shows the tubular body formedby win ding the sheet in spiral form. Fig. 3 shows the finished needle, with the sewing end reduced in diameter, showing the threadentering slot. Fig. 4 shows my invention applied to a hand. needle. 1

The numeral 1 designates a flat sheet of metal, formed with longitudinal beveled edges 2, a pair of slots j fiterminating in eyes 4 cut into one edge thereof, and its lower extremity cut away at an angle of substantially sixty degrees,'indicated by nu- .the needle, this sheet is wound into a spiral tubular form 6, with 'while the ease with whic the bevel on the inside, the ear adjoining the upper or thread entering slot 3, forming a protruding ear 7 for engaging the thread, and the angled lower end 5 of the sheet {Forming the needle point 8, as illustrated in 1g. 2. body forms the shankend of the needle, and beginning at a point immediately below the thread engaging ear 7, the tube is reduced in diameter, which, by reason of the beveled edges of the sheet, will open up a spiral slot 10 which terminates in the needle eye-41:.v

near the ear 7 and atthis point, the corner or car formed by the lower slot 8 in the sheet, will form a lip '11 which serves as a thread guard. This lip is bent toward the inside of the tube and set to almost close the slot 10 at that point but is suificiently resilient to permit the thread to pass it with a slight effort. The thread engaging The upper portion of the tubular ear 7 may be bent slightly in an outward direction, to afiord' positive engagement thereby of the thread when about to be inserted in the needle.

In threading the needle, the thread is slipped down the shank portion until it engages the ear 7 where it will pass into the slot 3 to the eye 4:. The free end is then pulled downwardly and it will follow the spiral groove 10 until it passes the guard 1.1, after which any upward pull thereon will draw it into the eye 1.

In Fig. 4 I have shown my invention applied to a the spiral groove 13 is formed in the opposite or eye end of the needle and the needle guard 15 projects inwardly to partiallyclose the spiral groove as in the machine needle, but the thread is entered by passing it around the body of the needle and pulling it along the surtae man it enters the slot or groove 13 and it is then drawn past the guard and into the eye 14. v

y above described, in a tubular form, I secure the maximum strength and resiliency be entered is evident.-

the thread may hand sewing needle. In this case I forming a sewing machine needle as Having thus fully described my inventhread engaging ear at'the opposite end of tion, what I claim and desire to secure by the slot. 10
