NEEDLE THREADER Filed Jan. 14, 1942 INVENTOR WITNESSES lUa/fer Pan 5 n3 Patented Aug. 18, 1942 UNITED STATES PATENT OFFICE NEEDLE THREADER Walter Parsens, Brooklyn, N. Y. Application January 14, 1942, Serial No. 426,665

3 Claims.

This invention relates to needle threaders and involves an improvement over the type shown in my Patent No. 2,115,999, dated May 3, 1938.

An object of the invention is to improve the structure shown in my prior patent and to simplify the operation of the device.

The particular object of this invention is to provide means for disengaging the thread from the threading hook after it has been drawn through the eye of the needle, so that the threaded needle may be removed from the feed shoot without danger of the hook unthreading the needle by pulling the thread from the eye.

Further objects of my invention will become more apparent as the description proceeds.

In the accompanying drawing Fig. 1 is a side elevation of an embodiment of my invention;

Fig. 2 is a side elevation in cross section;

Fig. 3 is a detailed sectional view showing the position of the parts as the needle is threaded;

Fig. 4 is a view similar to Fig. 3 showing the threading operation;

Fig. 5 is a sectional view showing the position of the parts after the operation has been completed;

Fig. 6 is a cross-sectional view taken on the line 6-6 of Fig. 3.

In the drawing I have shown the feed shoot encased in the figure of a bird, but this is purely for ornamental purposes and any suitable structure may be used.

My device includes a frame plate l which may be bent over at the bottom II to engage a clamp |2 so that the device may be positioned on a table or other member I3. To the upper edge M of the frame plate l2 there is attached a bent spring member I which may be integral with the frame member I9. The spring member l5 may be continued to form an arm l5 which is bent back upon itself to form the member IT, as shown in Fig. 6. This bent-back portion forms a channel l3 through which the upper end of the hook I9 is adapted to pass. The hook I9 is mounted on the upper end 29 of the frame plate l0.

Pivoted within the spring member I5 is a shoot member 25 which may be supported by a bushing or washer 26 through which a pin 21 extends. member assumes the figure of a bird, but it will be understood that any suitable structure may be used.

Mounted in the shoot member 25 is the feed shoot 28 which may be more or less funnel- As shown in the drawing, the shoot i shaped at its outer end 29 and reduced to a tube at the other end 30.

A plate 3| is pivoted at 32 to the frame plate H] by means of a rivet pin or by any suitable means. Attached to the plate 3| is a stop member or guard plate 33 which is bent upon itself to surround the arm l3 and to extend above the arm IE to protect the hook l9 and to govern the position of the needle. At the opposite end of the plate 3| is an arm 34 having at its outward end a hook 35. A pin 36 extends through the shoot frame 25 and the arm 34 slides on this pin until the hook 35 engages it.

In operation a needle 43 is placed in the shoot 28 with the tube 3|] of the shoot in the downward position, as shown in Fig. 1. Naturally, the eye 4| of the needle must be inserted in the shoot first. The thread 43 is then placed in loop arrangement over the beveled edge 44 of the stop plate 33 and pulled downwardly. This action flattens the eye of the needle and causes the hook |9 to pass through the eye 4| and engage the thread 43, as shown in Fig. 3. It will be appreciated that this action is against the tension of the spring l5. As soon as the thread is released, the arm I6 will be returned by the spring I5 to the position shown in Fig. 4 with the hook l9 drawing the thread 43 through the eye 4| of the needle. It will be noted that in this position the hook I9 is resting in and covered by the channel l8. As the nose of the bird is raised, the bar 34 will slide on the pin 33 tipping the plate 3| on its pivot 32 to uncover the hook l9 as the thread is drawn farther through the eye 4|. This will quickly disengage the thread 43 from the hook l9, as shown in Fig. 5, and the threaded needle may be removed from the tube 30 with the thread entirely free from the device.

I claim:

1. A needle threading device which includes a frame, a depressible spring plate mounted on said frame, a chute to receive and guide the needle to the proper position on the frame, said chute being pivotally mounted on the frame, a guide or stop plate disposed at the end of said spring plate to limit the movement of the needle, said stop plate being pivoted to the frame and having an arm extending over said spring plate, a pin upon said chute member, said arm being adapted to slide on said pin when said chute is pivoted on said frame.

2. A needle threader including a frame, a depressible spring plate mounted on said frame and adapted to support a needle, a hook mem ber mounted on said frame adjacent the end of said spring plate, a chute pivotally mounted on said frame, and a stop member pivotally mounted on said frame and surrounding said hook, said stop member having an arm in slid- 5 ing engagement with said chute adapted to pivot said stop member when said chute is pivoted to uncover said hook.

3. In a needle threader, a frame, a hook mounted on said frame, a spring plate on the other end of said frame bent upon itself to surround said hook, a chute member pivoted at one end of said frame, a stop plate pivoted to said frame, an arm on said stop plate slidably engaging said chute member and adapted to pivot said stop plate to uncover said hook when said chute member is pivoted.
