IV JA 06H ATTORNE 2,090,678 Patented Aug. 24, 1937 UNITED STATES PATENT OFFICE ‘ ' 2,090,678 I an??? - . N. J. ' > Application April 20, 1936, Serial No. 75,3ii2 3 Claims. (cl. 2223-99) ‘This invention relates to appliances for facili tating the work of hand sewing and more particu , larly to needle threaders. The main object of the invention is to provide 5 a device by which any common sewing needle may be assuredly and easily threaded with suit able thread, the same being passed through the eye of the needle in a positive manner. A further feature is in the provision of means ‘ 10 whereby the needle to be threaded is automatically. ‘ adjusted into position to receive the thread when fully entered into the device. Another purpose is to produce a. needle threader by the bight 23 the showing of the curve in Fig ure 1. being exaggerated. A common sewing needle 25 provided with a ?attened head 26, containing the eye 22, is en gaged, when fully entered into the threader, in 5 a rectangular aperture ‘28 formed in the solid base 29 of they circular opening to receive the needle. In operation, the needle iszentered so that its head is seated in thesocket 28, whereby the eye 22 is alined and caused to register with the 10 opening l3 between the spaced walls of the threader. > — _ Thereafter the slide H is pressed inwardly until I the pin 2c limits its movement. The loop 2! convenient to operate, even by unskilled persons, 5 and which is small and compact, forming a use ' passes through the needle eye, the opening it ‘and 15 ful adjunct to- the appliances usually employed by a seamstress. These desirable objects are accomplished by the novel and practical construction and com~ 20 bination of simple parts hereinafter described and illustrated in the accompanying drawing con stituting an essential component of this disclosure‘ and ‘in which: ' Figure 1 is aisid'e elevational view of an em 25. bodiment of the device. Figure 2 is a central longitudinal sectional view of they same, parts beingshown in another posi tion. ' ~ Figure 3 is'a transverse sectional view taken on 30 line 3-3 of Figure 1. , li'igure'4 is a further enlarged fragmentary ' sectional view showing the needle receiving socket. Referring in- greater ‘detail to the drawing, the main part of the device, designated by thenu , 35 ‘meral It), consists of a narrow casing, generally a truncated triangle, its outer, smaller end being open and its‘ closed, opposite, or base end J2 curved semi-cylindrically by folding the thin plate constituting the side walls and provided with a perforation l3 in the extreme portion of the curved closure near its bottom. ‘Engaged around this curved element is a forked socket M from which projects a sheath i5, closed 45 at its outer end and having‘ a transverse opening i6 alined with the perforation IS. ?nally presses its bight 23 against the curved outer wall of the element 15 causing the loop to . expand, as best seen in Figure 2; thereafter a ~‘ thread 30 is entered through‘th'e opening 16, and, obviously also the loop 2i thus expanded. , 20. Upon drawing-the slide outwardly, the thread 30 is‘ drawn through the eye of the needle, com pleting the threading, operation, whereupon the needle may be withdrawn, ready for use.‘ ' _, It is to‘be understood that the sheath i5 may 25 be'omitted and/the loop 23 expanded by pressure, as' fromv an operator’s ?nger, thus providing _ means for threading a sewing machine needle, 'the operation of which will be apparent. Although the foregoing is descriptive-of the pre-_ 30 ferred embodiment of the‘ inventor, it will be apparent that minor changes may be made in its construction, without the exercise of invention or con?icting with the scope ofethe claims hereto appended. ‘ 35 Having thus described the invention, what is claimed-‘as new anddesired to secure by Letters Patent, is: > g V _' 1. A needle threader comprising a thin, ?at casing adapted to receive the shank of a needle 40 upright therein, means to compel the eye” of the needle to aline with the space between the walls of said casing,‘ a spring loop guided by the casing walls to pass through the\needle eye, a closed sheath on said casing to expand said loop after 45 A slide [7, provided with a lip i8 to act as a _ passing through the eye to receive a thread, and handle, contains a central longitudinal slot 89 manual means for actuating said loop to cause and-is freely movable between the walls of the 50 casing I 0, 'being limited by a pin 20 at either its expansion.’ » " 2. A needle threader comprising a thin, ?at casing having a needle receiving socket, a slide 50 ’ Fixed rigidly in the inner end of the slide is a movable longitudinally between the casing walls, means to limit the movement of said slide, a sec flexible loop. 2! of ?ne wire adapted to pass ond casing engaged with the ?rst casing and hav- j through the eye 22 of a needle, the loop having ‘ ing a closed outer end and a spring 'loop'carried Q 65 opposed, slightly out bowed members connected by said slide'to pass through the eyeof a needle, 56 extreme movement. 2 _ 2,090,678 through the eye of a needle entered fully into said ' and a sheath carried by said casing pre closed end of said second casing whenseid slide socket, sentin'g an abutment in said casing adapted to ‘ said loop being expansible by-contact with the is pressed inwardly to its limit. 3. A needle threader comprising a thin ?at expand said loop to receive 'a. thread to be drawn casing having a. transverse needle receiving socket, a. slide movable limitedly between the walls ‘inwardly through the to its needle limit.eye upon pressing said slide of said casing, a. loop carried by said slide to pass CHRISTIAN JAUCH.
