NEEDLE THREADER Fi led Feb. 27, 1935 Patented May 26 1936 PATENT JOFFI'CE NEEDLE .THREADER Andrw Hrivna Application February 1 Claim.

This invention relates tocertain new and useful improvements in needle threaders.

The primary object of this invention is to provide a needle threader of the type employing a loop formed of a filament of thin gage wire having the free ends thereof secured to a button or other hand operating device capable of being slid in a hollow handle so that the wire filament may be retracted and completely housed within the handle.

A further object of the invention is to provide a needle threader of the above mentioned character having a threading element formed from a thin gage piece of stiff wire, shaped in such a manner as tocause the needle threader to be easily guided within the handle when the device is retracted and in its inoperative position.

A still further object of this invention is to provide a needle threader of the abovemen- 20 tioned character having a peculiarly shaped point so that after the thin gage Wire loop has been passed through the eye of the needle, the needle may be retained thereon in a frictional manner.

Other objects and advantages of the invention will become apparent during the course of the following description, taken with the drawing wherein, 4

Figure 1 is a top plan view of an embodiment of the invention illustrating the wire loop memher extended ready for insertion in the eye of a needle so that the thread may be passed through the loop with the resultant drawing of the thread through the eye of the needle thereby completing the threading operation;

Figure 2 is a modified form of the invention illustrating the thin gage wire loop member bent along portions of its length inwardly for frictionally retaining the needle in place while the thread is being extended through the loop formed by the thin gage wire;

-. Figure Lisa. still furthenmodified'form,of the invention illustrating the free ends of the thin gage wire loop secured to a handle formed of twisted wire.

In the drawing, wherein for the purpose of illustrating the invention and wherein like reference characters will be employed to designate like parts throughout the same, attention is first directed to Figures 1, 3, 4, 5, and 6 wherein the reference character 5 will generally be employed to designate a Wire loop member formed from thin gage stifi wire being bent upon itself as at 6 and having portions 1 extending parallel for a portion of their length and bent inwardly as at 8 to extend parallel for the remainder of their length.

The inner ends of the thin gage wire member 5 are secured to a button by means of solder or the like and said free ends converge inwardly toward the manual operating button In as at H.

The needle threading loop member above described is adapted to be slidably mounted within a handle 12 which is preferably formed of sheet metal bent in such a fashion as shown in Figure 6 as to form a slideway 13 for 'housing the needle threading loop member.

The manual operating button is adapted to be guided in opposite slides I4 formed in the handle member l2 and the button I0 is prevented from displacement by means of a washer l5 secured to the reduced end l6 of the button by As shown in Figure 2, the handle of the needle threader is substantially identical as at Hz: and is also provided with a longitudinal slot Ma on opposite sides thereof for slidably guiding the button Illa, The needle threading loop 5' also comprises a piece of thin gage wire return bent as at 6 and is further provided with parallel portions 1' extending parallel for a portion of the length whereupon they are bent inwardly in a curved manner as at 8' and extend outwardly as at 8a to form a loop for receiving the thread T. The bent wire portions 8a converge inwardly as at 8b and continue in parallel relation for the remainder of their length. V

The inner ends of the wire loop member 5 are secured to the button Illa in the same fashion as the inner ends I I are secured to the button Ill.

The needle N when being threaded may be received upon the reduced inwardly directed portions '8' whereby the thread T may be extended to the loop 5' and upon' withdrawal of the thin wire loop 5' the thread T may be carried therewith and through the eye of the needleN. The

r j operation of the needle threader shown in Figs. 1, 3, 5, 4, and 6 is substantially identical to the operation as shown in Figure 2 and in Figure 1,

the needle threading loop' 5 is in position or alignment with the needle N to be extended through the eye thereof whereby the thread T may be passed through the loop 5 and the loop withdrawn from the eye of the needle, thereby leaving the thread in position within the eye.

In Figure '7 is shown a still further modified form of the invention and the threading loop A is 7 formed of thin gage'wire return bent as at B and extending in astraight line or in parallel relation for a. portion of its length as at C. The loop A is spread so that the opposite wireniembers are arcuately curved as at B and the free ends of the loops A are secured together by whipping E thereby forming a handle'having a loop F at the free ends so that the device may behung upon a hook or other form of support.

The needle threading device shown in Figure 7 may be used in a similar fashion to the threader shown in Figures 1 to 6 inclusive.
