Jan. 4,, 1944. H. w. APPLETON NEEDLE'THREADER Filed Margh 3, 1941 INVENTOR l/E/VEY MAP/345m 6 5- ATTORNEY Patented Jan. 4, 1944 UNITED STATES PATENT, orFlcs Henry W. Appleton, Passaic, N. J Application March 3, 1941, Serial No. 381,571

Claims. .(Cl. 223-99) This invention relates to needle threaders and, a more particularly, to such adapted for threading needles of various sizes.

The principal object of my invention, generally considered, is to provide a device for threadin a hand sewing needle which will be simpler, cheaper and more certain in operation than those now on the market.

Another object of my invention is to provide a simplified needle threader consisting essentially of a threading element proper, a housing, and means for pivotally mounting said threading element in said housing.

A further object of my invention is to provide a needle threader which is dependable, foolproof in operation, and adapted to accommodate a wide range of needle sizes.

Other objects and advantages of the invention, relating to the particular arrangement and construction of the various parts, will become apparent as the description proceeds.

Referring to the drawing illustrating my invention:

Figure 1 is an enlarged side elevational view of a needle threader embodying my invention.

Figure 2 is an end elevational view, looking at the needle threader from the left as seen' in Figure 1, modified.

Figure 3 is a transverse sectional viewon the,

line IIIIII of Figure 2, in the direction of the arrows. I

Figure 4 is a transverse sectional view on the line IVIV of Figure 1, in the direction of the arrows.

Referring to the drawing in detail,like parts being designated by like reference characters, the body portion, casing, or housing I!) of the needle threader illustrated is composed of two complementary parts, I! and I2, which together form a recess It in which a threading element or hook device I4 moves. The recess may be formed part- 1y in one half, II, and partly in the other half, l2, of the housing W, as illustrated, or it may be all formed in one of said parts. The housing I0 is desirably formed of a plastic composition moulded to a desired shape such as illustrated, but it may be made of stamped metal or other suitable material. One of the halves, such as H,

' eye 29 is is desirably formed with outstanding "dowels l5,

' I6, I! and I8 snugly receivable in corresponding recesses'or pockets l9, 2|, 22 and 23 inthe cooperating member l2. In this way the parts are held in proper relation with respect to one another.

The threader or threading element I4 is desir receive the ably formed'as' a: spring metal stamping. It is relatively thin and resilient, and comprisesal'hub 24 through which passes a rivet, eyelet or other pivotal member 25, which performs the additional function of holding the parts ll and I2 of the housing together. An additional rivet. or rivets may be employed if desired to hold the parts of the housing together. The hub 24"'carries a radial arm 26, from the free endof which extends a desirably circumferential" or curved portion 21 terminating'in a hook 28. The relation between the cavity l3 and the thicknessof the threader element I4 is such that it is guided at all times and prevented from moving to' any appreciable extent from its pres'cribedpath.

In order to operate the threadingele'ment Mso that it swings from the position indicated in'tlie full'lines in Figure3, to'that shown in do ted lines where the hook portion 28- passes through the eye 29 'of a needle 3 l, there is in the present embodiment an operating arm 32 which extends from the hub 24 beyond the boundary of the housing [0, so that it maybe moved by a finger of the operator.

In order to hold a needle 3| in place, the-hous ing portions II and I2 are provided with cooperating grooves 33 and 34 which together provide'a'generally cylindrical pocket or well 35 for the reception of 'said needle. The needle 'well ex,- tends from the top of the casing 10 as viewed in the figures, to below the cavity l3, so that the normally positioned on the circumference which is'traversed by the hook 28 when the threading element is moved to the dotted position, as viewed in Figure 3. 'The lower endof said well 35 is formed so that when the needle 3-? is dropped in place, to the position illustrated, it

turns if necessary so that its eye is in position to ook; 28., That is,'thelower terminal ;of-the needle well is generally pointed in vertical section, as indicated at 36in Figure 1, as viewed from the side, while'trunca'ted in vertical section as viewed from the end of the housing, as indicated by the reference character 31 in'liigureiz Intermediate horizontal sections are, therefore, generally oval orelongated.

The portions of the housing beyond the'needle well '35; that is. at the other side of saidwell from the rivet 25 and'threader cavity l3, are spaced as indicated to provide a thread release 'slot The peripheral contour about said slotted portion is as seen at the left of Figures 1 and 3; that is,

there is a notch 39 for thereception ofthe thread 4|, shown in. place in section,

said notch being defined by an "nderlyingprojection 43' extending beyond the spaced portions providing for the thread release.

The needle threader cavity I3 is extended into the projection 63, as indicated at 44, to receive the hook portion 28 when the threader I4 is projected through the eye 29 of the needle 3| The function of this construction is to insure that the threader hook 28 is housed at all times, and so avoid any possibility that it may become accidently damaged in use. The notch 39 extends below the path of movement of the hook portion 28 so that when the thread is drawn toward the extreme root of the notch, the hook upon its return movement will engage the thread and draw it through the eye of the seated needle 3|.

The threader recess 13 desirably terminates in a shoulder 45 against which the radial arm 26 abuts at the limit of its outward movement, and a shoulder 46 against which the operating arm 32 abuts at this point. The recess shoulders 41 and I8 likewise serve as abutments for the arms 26 and 32, respectively, at the limit of their inward movement.

The threader disclosed may be operated as follows:-The device is held between the thumb and second finger of one hand, with the index finger on the arm 32 with the needle well 35 in a vertical or approximately vertical position. If the threaderelement I4 is not in the position shown in full lines in Figure 3, the index finger is moved forward toward the needle well, moving the arm 26 and hook portion 28 rearwardly to that position.

The needle 3! is then dropped eye down into the needle well 35. The shape of the seat 3631, and the fact that it is of proper depth so that the eye lies on the path of movement of the hook '28, causes the needle to come to rest in the position illustrated.

The index finger then moves the arm 32 away from the needle well and thus causes the hook 28 to pass through the eye 29 of the needle 3|, to the position shown in dotted lines in Figure 3.

The thread, shown in cross section at 4|, is now drawn across and down towards the bottom of the thread channel or notch 39, which brings it into position to be caught by the hook 28 upon its return movement to the full line position shown in Figure 3, where it draws a loop of thread through the eye 29.

The needle may now be withdrawn from the needle well with a double thread through its eye. .In order to be sure to release the thread from the hook 28, the latter is caused to move partly toward the needle well, and the needle may then be withdrawn without difliculty from its well, the thread passing through the thread escape slot.

From the foregoing description it will be seen that I have devised a needle threader which is simple in construction, eflicient in operation, and durable in that there is no danger of unintentional damage to the delicate threading element. On account of the preferred .manner of formation of the threading .or hooked element, the same is adapted to bend slightly in the plane in Which it lies and so accommodate .itself to needles of diiferent sizes and eye positions, that it will pass through the eyes of .a greater variety and number of sizes of needles than most other needle threaders.

On the other hand, on account of being confined closely in the receiving cavity, there is little danger that it will be bent out of shape. Should the hook become caught on a thread, any

yank or pull will be transferred to the hook only as a straight tension in the direction of the length of the hook, and on account of the high tensile strength of the metal forming the hook, no harm can be done. As the hook is protected against a sidewise pull beyond the clearance limits of its cavity, it cannot be bent sidewise or out of the plane in Which it normally lies.

Although a preferred embodiment of my invention has been disclosed, it will be understood that modifications may be made Within the spirit and scope of the appended claims. It will also be understood, that although the dowel pins, I5, it, I! and 18, are preferably integral with one half of the housing H], such as H, for example, and snugly received in the pockets i9, 2!, 22 and 23 of the other, as shown in Figures 1 and 4, of the halves l l and I2, yet they may, if desired, be formed separate and snugly fit both halves for the same purpose, as shown in Figure 2.

I claim:
