T. 1. BOWYER. SEWING MACHINE THREADING ATTACHMENT.
APPLICATION FILED IAN. 29,}916- Patented Sept. 11, 1917.

SEWING-MACHINE THREADING ATTACHMENT.
To all whom it may concern:
Be it known that I, THOMAS J. BowYER, a citizen of the United States, residing'at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Sewing-Machine Threading Attachments, of which the following is a specification, reference being had therein to the accompanying drawing.
My invention relates to improvements in sewing machine threading attachments, the primary object of which is to devise such an attachment which may be easily applied to any of the sewing machines as present on the market.
Another object of the present improvement is to so construct the attachment that it is adapted to be attached to the pressure bar of the sewing machineand remain attached thereto, so that it will be available at all times when it is desired to use it.
A still further object of the present im-- provement is-to devise such an attachment which is simple, compact, and inexpensive to manufacture.
Other objects and advantages of the in- 'vention will be set forth in the following description and drawings, in which- Figure 1 is a fragmentary perspective view of a sewing machine showing my improved threading attachment applied to the pressure bar thereof.
Fig. 2 is a top plan view of the attachment showing the pressure bar of the sewing machine in section.
Fig. 3 is a side elevation and sectional view taken on the line 33 of Fig. 2.
Fig. 4: is a bottom plan view of the attachment. s
Fig. 5 is a horizontal sectional View of the attachment taken on the line 55 of Fig. 3.
Fig. 6 is a perspective view of the position of the needle, thread, and threading hook of the attachment showing the said parts in separated relation.
Fig. 7 is an end elevation of the plate showing the guiding members for the reciprocating threading shaft.
Referring now to the drawings in detail in which like reference numerals designate similar parts throughout the several figures,
1 is a collar of such a design that it may be applied to the pressure bar of any sewing machine desired by merely enlarging or reducing the diameter thereof. After the Specification of Letters Patent.
Patented Sept. 11, 1917..
Application filed January 29, 1916. Serial No. 75,037.
pressure foot of the sewing machine has been removed the collar 1 is slipped onto the pressure bar and held in its adjusted position by means of a set screw 2. This set screw 2 holds one end of a band spring 3 which extends around one side of the collar and has its other end fitting within a horizontal slot l made in the collar 1. One side of the collar 1 is provided with an extension 5 which forms a bearing for an upright member 6 which passes therethrough and is held in position by means of the free end of the spring 8. The member 6 though of circular cross section, is provided with a flattened portion 7 which when engaged by the spring 3 will hold the member 6 and parts carried thereby in position to thread the needle, as will be hereinafter described. The upper end of the member 6 is provided with a horizontal extension 8 which serves as a handle and,'being provided with a notch 9, which engages the shank of the sewing machine needle 10 forms a stop for the threading portion of the attachment, as will be hereafter set forth. The lower end of the member 6 carries a tablelike extension 11 which as shown herein 1s made integral therewith, but this extension 11 may be made separate and attached to the member 6 without departing from the invention herein. One side of the extension 11 is forked as at 12 to engage the needle 10 just above the needle eye. That part 13 of the fork which goes behind. the needle is so formed that it acts as a guide rest to hold the thread in position when threading the needle. The other portion 1a of the fork is flanged downward on one side in such a manner that the thread can be guided along it to a point below the needle eye. A notch is also made at the base of this portion, which notch is numbered 15 on the drawing. This notch 15 is for the purpose of causing the thread when approaching the needle to slip up and rest across the needle eye and in position to be engaged by a fine hook, here after to be described, which passes through and extends beyond the needle. The front side of the extension 11 is rolled over and under so as to form bearings 16 in Which is slidably mounted a small rod 17 which works back and forth carrying a fine hook 18 which is designed to pass through the needle eye and engage the thread 19 as is clearly shown in Fig. 6. The rod'17 is provided with a notch 20 in the upper face thereofwithin which fits a spring 21 having one end iastened within the lower end of the member 11 as at 22: ThisspringQlboth serves to keepthe hook in alinement with the eye of the needle and'especially to keep the rod 17, and fine hook 18 away from the needle. Theouter-endofthe spring 21 is twisted at 23 to serve as a handle to move the rod and hook, so that the hook may be inserted.throughthe needle eye and drawn back: carryingwith it thethread-19. QfL-is a coil spring-which encircles the upright member 6 and resting on the collar 1 tendsto keep theuprighti member 6 raised with relation to the collar.
the sewing machine in case of careless adjustment.
To operate. the device the attachment, through the medium-of the horlzontal memher 8 serving as. ahandle, is swung around until: the said handle springs lnto contact withtheshanln of theneedle, the flattened portion of the upright. member 6 and the band spring 3 serving to accomplish this result.
hook lSrarried by the rod. 17 directly behind the eye of the needle. The hook bar is then shoved forward by pressure applied to the handle 23luntil the hook l8 extends through the needle eye. The thread 19 is then brought'underand across the fork12 of: the extension 11 and drawn backward until it; slips into the notch 15 in the arm 14 of the fork12 and under the hook 18 of the slidable rod 17. The appliance is then swung'away from the needle carrying the thread through the needle eye.
Having thus described my invention,- what" I claim and'desire to secure by Letters Patent is:
'1'. Athr'eadingattachment for sewing machines comprising'a member attachable to the pressure barofthe sewing machine, a. horizontally disposed L-shapedplirte carried by the said member, said plate extending. from a point" at one side ofthepressure bar. forwardly and around in front of the needle,
Its purpose is to, keep the horizontal portion 8 of: themember 6 in contact with the needle holder of.
Thefork 12 of the extension 11. then embraces the needle 10 with the fine ber mounted .in. said .guideWa-ys and having a i hook on oneend I adapted to pass through. the eye of the. sewing machine: needle, a. spring. having .one endsattached @130 the. :under: side of; the. plate andzengaging thetop of.
the slidable-memberfon normally holding.
the hook away fronrthe. needles 3.. A. threading attachment. for; sewing machine needles: comprising a member: ate 7 tachable to the pressure bar of'the sewing machine, a horizontally. disposed plate caririedi by "the said member, said 1 plate having a notch in one edge to receive the sewing machine needle, another. edge of the said plate rolledftoform arguide-Way diametri-- cally behind theisaid notch, and a slidable members mounted r in: said guidewayand carrying means for threading the needle.
4. A threading attachment for sewingmachine needles 2 comprising a member attachable to the pressure-har ot thesewing machine, a horizontally disposed plate carried by the said member, one edge of the said plate rolled to form a: guideway,-a slidable member mounted in the said guideway, a"
portion of the guideway cut away, a spring hav ngione end attached to the plate and having a: handle ontheother end passing throughthe cut-away portionin the guideway and attached to the slidable member providing means for moving the slidable member between the limits of thecut-away portion.
In testimony whereof I hereu'nto afiix my signature in-the presence of'two witnesses.
