NEEDLE-THREADER.

SPECIFICATIN forming part of Letters Patent No. 524,896, dated August 21, 1894.

Application led April 80. 1894. Serial No. 509.542. (No model.)

To all whom it may concern,.-

Be it known that I, CIMON SQGOLDMAN, ot'

New York city, in the county and State of i that class of devices which are used for threading needles and which are especially adapted for threading needles of sewing machines! l The object of my inventionis to produce a simple device ot this character, which may be easily applied to the needle bar and needle of asewing machine, which maybe adjusted vertlcally and laterally so as Vto perfectly :tit the needle, and which is provided with a threading hook adapted to find the needle eye 1n a positive way and penetrate the needle eye, engage a thread and automatically pull the thread through the eye, leaving it' ready for use, and thus rendering the threading process quick and easy.

:To these ends my invention consists of cer tain features of construction and combinations of parts, which will be hereinafter described and claimed. A

Reference is to be had to the accompanying drawings, forming a part of this specification, 1n which similar gures of referenceindicate corresponding parts in all the views.

Figure 1 is a central vertical section of my improved device, as applied to the needle bar and needle of a sewing machine. Fig. 2 is a detail perspective view of the needle threader. Fig. 3 is a broken detail sectional plan of the body of the device, showing the shape of the bore in which the threading hook is held and guided; and Figet is a detail vertical section of a modified form of the device as applied to a sewing machine and needle. l

The needle threader has an elongated body 10 which, at one end is provided with an upwardly-extending oset 11 which is grooved longitudinally, as at 12, to enable it to lit snugly any needle 13 carried in the customary way by Iche needle bar 14. The body has at its front end and on opposite sides forwardlyprojecting lips 15, which are adapted to eX-l tendon opposite sides of the needle so as to protect the threading hook when it is thrust forward through the needle eye, as hereinafter described, and theselips are also notched at their inner ends, as shown at 16, to enable the thread to lie therein and be held directly opposite the eye of the needle, so that the hook 17, when it is thrust through the needle eye may readily engage the thread. The hook 17 has a rearwardly extending shank 18 which slides in the longitudinal bore 19 of the body, and this bore is, at its front end, reduced gradually and tapered, as shown clearly in Fig. 3, so as to guide the hook 17 in a positive and accurate way to enable it. to enter the eye of the needle.

Secured to the shank of the hook is an upwardly-extending rod 21 which moves inl a slot 22 in the top of the body 10, and the top of the rod is held in a slide block or plunger 23 which moves inthe hanger tube 24, this tube being closed at one end and having the other end open and slightly enlarged, as shown at25, to enable it to be readily applied to a set screw 26 on the needle bar 14, but it will of course be understood that the threader may be used Without attaching the tube to the set screw, althoughthis is desirable.

The plunger or slide block 23 has a shank 27 which extends back through a guide 27' in the tube and outward through the back end of the tube, where it terminates in a finger piece 28 and it is normally pushed back by a spring 29 which encircles the shank 27 and, by pushing the shank back draws back the plunger, the rod 21 and the hook 17. The slide block or plunger 23 `may be held in any suitable way, but as illustrated, it has set screws 31 on opposite sides which move in slots 32 in the tube and which serve to fasten the rod 21 to the slide block. The tube at the top and bottom,is longitudinally slotted, as shown at 30, to provide for the movement of the rod 21.

To the under side of the tube 21 is secured a hanger 33 which projects downward through a lug 34 on the back of the odset 11 and the lug is fastened to the hanger by a set screw IOO finger piece 28 lwhich forces the hook 1'7 thrOllgh the needle eye and into engagement withthe thread, after which the linger is removed and the spring carries the hook back and draws the thread through the eye so'thatl when the needle threader is removed the needle is left threaded ready for use.

The threader is preferably constructed as described, with the finger piece 28 opposite the needle bar, as this removes all strain from the needle when the finger piece is pressed, but if desired. the threader may be made as shown in Fig. 4, where a short tube 36 is used as a hanger tube, this having on its under side a lug 37 in which is held the angular hanger 38 which is fastened by a set screw 39 extending down through the tube 36.. The vertical portion of the hanger 38 extends through :the lug 34 on the oset 1l and is fastened by .a set screw 35, as already described, and it will be seen that the construction shown in Fig. 4 enables the bodyv 10l to be adj usted both vertically and longitudinally. In the body 10 is held the shank 18 of the hook 17, but

V.the shank projects beyond `the rear end of the body and is provided with a finger piece 38 and it is normally pulled back by a spring 4.0 .which encircles the shank .and is fastened to the shank and to thev body 10. The threader shown in Fig. 4 is applied in the mannerabove lspecified, but is operated by pressing the finger piece 38, .which forces the hook through with the result above specified.

Having lthus described `rny invention, I

claim as new and desire'tosecurebyLetters body and` adapted to penetrate a needle eye,

a hanger tube held to engage the set screw of a needle bar,and an adjustable connection between the hanger tube and the body,sub stantially as described.

2. The combination, with thelongitudinally bored body and the slotted hanger tube, of a connection between the tube and body, a sliding threading hook held in the body, a springrepressed slide in the yhanger tube, and a rod connecting theslide and hook, substanmally as described.

3. A, needle threader, comprising a hollow body,..having a grooved odset at its frontend to fit aneedle withparallel guardy lips on the lower end of the offset,alug or keeperon the back of the olf'set, a hanger tube adapted to be suspended on the setscrew of a needle bar, anarm on the hanger tube` extendingdownward through the lug or keeperlon theoset, a threading hook held in the hollowbody, a spring-repressed ,slide in the han gertube, and a rod connecting the slide and hook, substantially as described.
