HAND NEEDLE THREADERS Filed May 7, 1959 INVENTOR. Carl E. Corlsen.

ATTORNEY.

3,022,927 HAND NEEDLE THREADERS Carl E. Qarlsen, 867 2rd Ave., New York, N.Y. Filed May 7, 1959, Ser. No. 811,596 1 Claim. (Cl. 223-99) This invention relates to new and useful improvements in hand needle threaders, as well as to the threading of sewing machine needles, and it has for its object to provide a needle threader that is more adaptable and easier to use than those now commonly known hook needle threaders.

In addition, the needle threader, as devised, will be more durable in the mode of operation of threading a needle as the use of said needle threader will minimize the strain laid upon the slitted hook part of same by reversing the threading operation by actually passing the thread through the needle instead of pulling it through, as is now commonly done, thus preventing breaking of the book.

The present invention consists in making a tool, or needle threader, which is constructed with the hook portion in reverse so as to permit the thread to be pushed through the needle and cause said thread to slide off the needle threader unobstructed.

Thus by the construction and incidental operation has been eliminated the pulling operation that, as said, very often breaks the small hook in the now commonly used needle threader, in which the needle is first placed over the hook and the thread next put into the hook and the needle pulled over both the hook and the thread.

In the drawing:

FIGURE 1 is an elevational view of my device, showing a hand operated needle threader.

FIGURE 2 is an end view of the needle threader.

FIGURE 3 is a side view of same, and

FIGURE 4 is an elevational view showing my needle threader applied to a sewing machine.

Referring more particularly to the drawing, and in further illustration of the operation of my devices:

FIGURE 1 shows a hand operated needle threading post in which denotes a spool with thread, a needle threader 11 having an elongated upper end 25 for suitable support of a manipulating hand 17; an upright member 12 formed at its top with a hook portion 13 is secured to said threader in any convenient manner, or it may be an integral part of the latter.

In operation a loop of thread 14, held tight, is placed over the hook 13 in the needle threader, as said hook is then held against the end of a finger of the hand 17; the needle to be threaded is held by the fingers of another hand (not shown) and placed over said hook and thread 14, and next brought down on these, as shown in dotted lines in FIGURE 1.

During said operation the index finger of the hand 17 rests against the top rear side 25 of the member 12 in order to facilitate the relative arrangement of the thread and needle, said finger at the same time steadies the retracting movement of the thread and needle when these are lifted upward, while during said movement the thread upon striking the book 13 enters the eye 19 of the needle and by a continued upward movement, the needle thus threaded leaves the top of the member 12,

ice

thereby making it possible for the fingers of the hand 17 to graps the thread now in the needle.

While the description of my invention, as hereinbefore set forth, applies especially to hand needle threaders, the principle of my said invention will, however, also, when applied to sewing machine threaders constitute an essential improvement of these.

As the sewing machines, however, are of different construction, some, for instance, with the eyes of the needles open from one side to another, and some from the front to the rear, it makes it necessary to select the needle threader suitable for the particular machine.

However, the features described and disclosed herein will in a broad way cover any type of needle threader that would be applicable to a sewing machine.

In the present device the needle threader is especially adaptable to the needle of a sewing machine, where the eyes are open from the front to the rear.

In such machines the most simple operation is obtained by pushing the needle threader with the thread through the eye, as shown in FIGURE 4 of the drawing.

Thus in this case you thread a needle threader first, and with one hand, the needle threader is directed through the eye of the needle, and the operator does not need to bend over or see the needle, but this operation may be accomplished blind-folded.

In the sewing machine illustrated, in part, in FIGURE 4, is shown a needle 20 having a slit 21 leading to the eyelet 22. A needle threader 12, with a handle 11, has a thread 24 placed in the book 13 of said needle threader in such a way that both ends of the thread are held taut between the handle of the needle threader and one finger; said handle 11 of the needle threader should be held in the way as shown in the drawing so as to guide the needle along the slit 21 until it reaches the eyelet 22, when the needle threader with the thread is pushed through the eyelet 22 of the needle 20, as shown in dotted lines, the grip on the thread is loosened and the needle threader is withdrawn, and the thread left in the eyelet to be taken hold or by the fingers, thereby obtaining an infallible and simple threading of said needle.

I claim as my invention:

A push-hook needle threader for hand sewing needles and sewing machine needles comprising a relatively elongated member and a threading element supported adjacent one of its ends to one side of an edge of the said member and extending longitudinally thereof in spaced parallel relation, the free end of the said threading element extending to substantially the corresponding end of the said member, the said threading element having a hook formed adjacent its free end with the undercut portion of the hook facing the said free end.
