Be it known. that I, ALnRED Arznnnsox, citizen of the .United States, residing at-Minneapolis, in the county new and usefulimprovements in Sewing- Machine-XeedleThreaders, of which the following is a specification.

The presentinvention provides an attachment for sewing"machines, toadmitof the needlebeing quickly, easily and conveniently threaded, the attaclnnent being of such formation as tobe' secured to the machine so as always to be in position for instant use, thereby preventing misplaceine'nt or'loss of the same should it be separated from the machine and employed as any other attachment required to be placed in position for use. The threader is of such construction and arrangement as not to interfere with the ordinary use of the sewing machine or the employment ofthe accustomed attachments, yet being fitted thereto in position for instant use when it is required to thread the needle.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accom mnying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and-minor details without departing'from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

Corresponding and like parts iare referred to in the following. description and indicated in all the views of the drawings by the some reference characters.

e The attachment consists of a clip 1, rod or bar 2 pivoted to the clip 1 and provided at-its lower end with a horizontal extension 3 and a threader fitted to the horizontal extension 3 and-com )risingguides 4 and a hook 5. The clip 1 is designed'to secure tl'ieattachment to the-pgesser bar 6 of a sewing machine, said clip ving an extension to which the rod or bar 2 is pivoted. The clip 1 may be of any construction so long as it serves the purpose of securing the attachment to the presser bar in thereqnired position. The rod or bar 2 may be connected to the clip 1 by a pivot fastening 7 of any type so long as it admits of the rod or bar swinging to carry the threader towards or away from the sewing machine needle 8. The horizontal extension 3 at the lower end 01' the rod or bar 2 forms a part of the latter and is flattened and receives the threader, which is adjustable thereon and adapted to be secured in the required pcsi tion by means .of a set screw 9.

The threader comprises a shank 10 which receives the horizontal extension 3, said shank being channeled and having its longi a distance to engage with opposite longitudinal edges of the horizontal extension 3. A slot 11 is formed lengthwise of the shank 10 to receivethe set screw .9, thereby admitting of the threader being adjustable on the horizontal extension 3. The'guides iconsistof plates arranged at a right angle to the shank 10 and prefer ably form a part thereof, said guides con sisting of a strip doubled uponitself and having its end portions flared to adniit'of ready adjustment of the threader to the sewin 'ma-. chine needle when required to three the latter. The hook 5 is extreinely'slender so as to pass through the eye of the smallest sized sewing machine needle and engagewith the thread and draw the same through the eye. Thehook 5 is provided with a shank 12 which is secured between the rear ends of the guides 4 by means of a set screw 13, said set screw also serving to draw the guides 4 together more or less to insure the point of the hook 5 passing through the e c ofthe needle when the threader is proper y adj ust ed. A spring 14 is mounted upon the pivot fastening 7 and its end,por t i ons project and engage with, resgectivel'v,-the clip 1 and the r0 or bar 2, sai spring serving to normally hold the threader elevated andvout of the way. v

When adapting the attachment to a sewv ing machine it is secured to the presser bar 6 by means of the clip 1, the threader being adjusted on the horizontal extension 3 to cause the hook 5 to pass through the eye of the needle 8 when the latter is lowered and the rod or bar 2'pressed downward into an approximately vertical position. The hook 5 is located about in the lane of the upper edge of the ides 4, so that when thrust through the eye of the needle the thread may engage therewith so that as the hook is withdrawn from the eye, the thread is carried therethrough. The attachment is exceedingly light and when in position is normally out of the way and when required for use may inci dentally be moved to cause the hook to assume'adposition to pass through the eye of the nee e when the latter is lowered or adjusted to the proper height. When releasmg the clip upon the rod or bar 2, the spring 14 comes into play and moves the same so as to throw the threader out of the way of the needle and needle bar, so as not to interfere with any attachments that may require connection therewith.

Having thus described the invention, what is claimed as new is:

v The herein described threader attachment for sewin machines, the same co pnising a clip, a r0 or bar having pivotal oonnctiow 'for securing the shank to the horizontal ex tension in an adjusted posit-ion, spaced guides forming a part of said shank, and a threaded hook secured between said guides.

In testimony whereof I aflix my signature in presence of two witnesses.
