NEEDLE THREADER.

APPLICATION FILED IAN-16,19I7.

' I N VE IV TOR 311m: flux/n11 A TI'ORNEV UNITED STATES B'UEL COUCH, OF SIOUX CITY, IOWA.

NEEDLE-THREADER.

Application filed January 16, 1917.

To all whom it may concern Be it known that I, Bonn CoUoH, a citizen of the United States, and a resident of Sioux City, in the county of l/Voodbury and State of Iowa, have invented certain new and useful Improvements in Needle-Threaders, of which the following is a specification.

The present invention relates to means for threading needles.

The present invention has for its primary object the production of an improved and simplified needle-threader.

Another object of the invention is the production of a needle-threader efficient in operation and wherein the cost of production and the skill required to manufacture is reduced to the minimum.

A still further object of the invention is the production of a needle-threader thoroughly efficient in operation, inexpensive in production and the operation of which is readily apparent.

WVith these and other objects in view, the invention, consisting in the construction, combination and novel arrangement of parts will be fully understood from the following description, reference being had to the accompanying drawings which form a part of this application and in which like characters of reference indicate corresponding parts throughout the several views, of which,-

Figure 1 is a side elevation of a needle threader constructed in accordance with the invention; Fig. 2 is a plan of the same; Fig. 3 is an enlarged vertical section of the same; Fig. i is an enlarged transverse section of the same taken on the line 4 of Fig. 3; and Fig. 5 is an enlarged end elevation of the threading slide.

Although I have illustrated and hereinafter described the preferred embodiment of the invention, I would not be understod as being limited to the specific structure chosen for illustration for various altera tions and modifications in the details of construction and arrangement of parts may be made without departing from the spirit and scope of the invention as defined in the appended claims.

Referring, now, to the illustrations, 6, represents the body of the device, preferably consisting of a blank folded upon itself to afford two parallel sides and having the free Specification of Letters Patent.

Serial No. 142,608.

edge portion of one side folded over the cor which may be termed the front end, arepressed almost together, leaving an opening therebetween, as at 8, only suflicient to freely admit the threading hook and thread as will hereafter appear, while the sides of the body portion to the rear of said end portion are sufficiently spaced to admit a sliding plate 9, which reciprocates within the body. The rear end of said plate may be formed with an enlarged ring,,10, to afford a convenient grip for actuating the slide. Adjacent its upper edge the slide is preferably sheared longitudinally as at 11, to afford a strip, 12, which slides adjacent the upper wall or that portion of the flap, 7, which bridges the sides of the body. The slide, 9, is preferably of spring material and the strip, 12, tends to spring outwardly, thereby maintaining con stant vertical alinement of the slide and body. The front end of the slide carries a forwardly-extending hook, 13, formed of very thin spring material and preferably having a relatively broad shank embedded in a depression, 14, in the end portion of the slide, the shank being secured therein by a bridge or strip, 15, extending across the recess, said bridge being compressed firmly against the shank.

The portions of the sides of the front end portion of the body below the line of the hook are pressed together as at 16, (Fig. 4) and in the body portion, at a point adjacent the rear end of the said first described front end portion is drilled a vertical hole 17 which extends from the top edge of the body to a point just below the line of the hook. The portion of the body at the lower end of said hole is formed with a seat, 18, for the eye end of the needle. This seat is elongated transversely, similarly to the needle seat disclosed in the patent to Bostad, No. 1,159,802. The said seat and hook being so relatively positioned that when a needle is inserted in the opening 17, and the eye end of the needle seated therein, that the eye of the needle will be properly alined to freely admit the hook.

The upper forward corner of the body is preferably rounded as shown, to add to the grace of the device and the front end portion is diagonally slotted as at 19, the said slot being extended downwardly and rearwardly to a point just in the'rear of the normal position of the hook proper. The lower end of said slot communicates with a relatively short longitudinal slot, 20. The portion of the body at the upper edge of said latter slot is positioned relatively a short distance above the reduced shank of the hook and affords only suflicient space to admit a strand of thread and serves to prevent displacement of the thread from the said space.

The rear edge portion of one of the sides of the body may have a portion sheared therefrom as at 21, which portion is dewardly, thereby carrying the hook through the eye of the needle to the position shown in Fig. A bight of thread, 23, is then passed through the diagonal slots, 19, to the position shown. The plunger is then with drawn carrying the thread through the eye of the needle as shown in dotted lines in Fig. 3. The needle may be withdrawn from the socket and the two strands of thread slipped, without effort, through the space or thread passage, 8, between the sides of the body, thus obviating the necessity of drawing the full length of the thread through the opening, 17.

Having thus described my invention what I claimras new and desire to secure by Letters Patent of the United States, is,-

1. In a needle-threader, a body consisting of .a blank folded upon itself to afford two parallel sides, a plunger slidable between the sides, one end portion of the body having a thread passage between the sides, and a needle-receiving hole extending downwardly from the upper edge of said portion and between the sides, a needle seat formed in the body at the bottom of said hole adapted to aline the needle eye longitudinally of the body and a threading hook on the-plunger adapted to pass through the-needle eye, the sides of said end portion being slotted to admit a bight of thread for engagement by the hook.

2. In a needle-threader, a body comprising a blank folded upon itself to provide parallel sides, a plunger-strip, the sides being spaced from each other for a portion of the length of the body to afford a passage for the plunger, and the sides of the remaining portion being spaced only sufficient to provide a thread passage therebetween, the latter .portion having a needle-receiving socket formed in its sides, a needle seat formed in the body at the bottom of the socket adapted to aline the needle eye longitudinally of theubody, the sides of the said remaining portion ,be- :ing provided with inclined slots to receive a bight of thread, and a hook on the plunger positioned to penetrate the needle eye and intersect the plane of the said slots.

. In testimony whereof, I have hereunto set my hand this 12th day of Jainuaiy 1917.
