NEEDLE-THREADER' Specification of Letters Patent.

Patented Nov. 3, 1914:.

Application filed September 2'7, 1 912. Serial No. 722,740.

To allwhom it may concern:

Be it known that I, WALTER WILLIAM h lAnrIN, a citizen of the Dominion of New Zealand, and residing at 4&1 Nairn street, elling-ton, in the Provincial District of lVellington, in the Dominion of New Zealand, have invented certain new and useful Improvements in Needle-Threaders, of i which the following is a specification.

The invention relates to threading hand, and machine sewing needles.

According hereto, a cone has a tapering axial hole through which the thread. is passed and guided to the eye of the needle. The smaller end of the cone has a projection, arranged diametrically, the middle of which is pierced by the hole through the cone. The projection .is adapted to engage in the thread groove usually found in sewing machine needles, or, in the eye of a hand sewing needle, forthe purpose of locating the needle in the correct position relatively to the hole to enable the threading to be ac complished. The cone is mounted upon a frame to facilitate handling and a spring device is employed to press the needle against the face of the cone and hold it in position.

It will be apparent that hand sewingneedles may be threaded by the device described as well as sewing-machine needles, but as some forms of hand sewing-needles have an eye which is not so well adapted to the particular form of my invention already described, I make a modification in the de scribed device, which modification may be combined with that described, so that both kinds of needles may be easily and quickly threaded. In carrying this into effect, the spring referred to is folded back upon itself, and a recess is formed to receive the needle in such manner that the eye is brought into correspondence with the hole for the cotton in the cone referred to. These, and further details of my invention will now be described by the aid of the accompanying drawing wherein Figure 1, is an end perspective elevation of one form of my invention. Figs. 2 to 6, inclusive are enlarged views and severally show :-F ig. 2, an end sectional elevation of the cone, Fig. 3, an end elevation, Fig. 4:, a sectional plan, and Fig. 5, a corresponding part rear elevation, and Fig. 6, is a similar view of a guide plate. Figs. 7 to 11 inclusive are plan views of the device shown in Fig. 1

and illustrating the operation of threading a machine-needle. Fig. 12, is an end perspective elevation illustrating the threading of the hand-needle by the same device. Figs. 13 to 16 inclusive are side perspective elevations illustrating the threading of an ordinary hand-needle.

The same numerals of reference are used to indicate similar parts throughout the figures.

Referring first to Figs. 1 to 6, inclusive, the block 1 fixed upon the frame 2 has a conical tapering hole 3, and a longitudinal slot 4. The inner face'of the cone has a proj ecting rib 5 adapted to engage in the thread groove of a needle and a projection 5" from said rib adapted to engage in the eye. The said hole is extended through'the middle of the projection 5. The flat spring member 6 is secured at one end upon the frame memher 2, and has a projecting stop piece 7 against which the needle 8 is laterally placed to guide the projecting. rib 5, and the projection 5 referred to into the thread groove of the needle. The spring member 6 is folded rearwardly upon itself to em brace a guide plate 9 (see Fig. 6) having the integrally formed inwardly projecting springs 10 and 11, which converge and are normally located one upon each side of a thread hole 12 formed in the member 6, and opposite to the hole through the block. The return portion of the member 6 is also provided with a correspondingthread hole 12*. These springs adapt themselves to varying sizes of needles and insure the eye being coincident with the holes,

Reference is now had to the below described figures as further illustrative of the operation of my invention:

Fig. 7 shows the threader being passed on to the needle laterally, the needle being between the frame 2' and the spring member 6. Fig. 8 shows it against the stop piece 7 with the projection 5 engaged in the eye of the needle, and the thread about to be passed through the hole in theblock. Fig. 9 shows the thread passed through the cone, the needle and the two portions of the spring member 6. Fig. 10 shows the device drawn laterally off the needle, the thread remaining therein. Fig. 11 shows the device drawn still farther away whereby the thread is passed out ofthe block 1 by means of the slot 1 and the end of the thread is free to be drawn through the holes 12 and 12 in the member 6. Fig. 12 shows how a hand-sewing-needle 14: is passed under the block so as to locate its eye exactly opposite to the hole through the block, the projection entering the eye of the needle. Although there is not a thread groove in this type of needle it will be found that the placing of the needle in position is easily effected.

Referring now to Figs. 13 to 16 inclusive, these illustrate the particular form of my device suitable for threading hand sewingneedles. he needle 15 is inserted in a hole 16 in the bend of the turned over portion of the spring member 6. It passes between the springs 10 and 11, (see Fig. 6) by which it is guided so that its eye is brought into correspondence with the hole through the block.

Fig. 18 shows the needle ready to be passed through the hole 16. Fig. 11 shows the needle in position with the thread about to be passed through the block. Fig. 15 shows the needle threaded. Fig. 16 shows it drawn out of the hole 16, the thread being drawn through the holes 12 and 12 The larger sizes of ordinary sewingneedles may also be quite as readily threaded by bringing the eye of such a needle into position between the back spring and the projection of the threader block, as illus- Gopies of this patent may be obtained for five cents leach, by addressing the trated in Fig. 12. The needle in this case lies not straight. with the center line of the threader, but across it, approximately in the same position with regard to the threader that is occupied by a sewing-machine needle while being threaded.

It will be observed that the same tapering conical hole through the head of the threader, for the guidance of the thread is used, whether sewing-machine needles or ordinary sewing-needles are being threaded. The operatlon of threading will be easily understood from the previous description.

hat I do claim and desire to secure by Letters Patent ofthe United States is In a needle threader, a frame member, a tapering hole through said frame member, a slot through one-side of said block communicating with said tapering hole, a spring secured to said frame member and a stop piece carried by said spring adapted to guide said needle into position opposite the opening in said block.

In testimony whereof I have signed my name to this specification in the presence of two witnesses.
