SPECIFICATION forming part of Letters Patent No. 760,427, dated May 24, 1904.

Application filed July 29, 1903. $erial No. 167,503. (No model.)

T0 at whom it may concern.-

Be it known that I, MARVIN L. ORANNELL, a citizen of the United States, residing at Troy, in the county of Rensselaer and State of New York, have invented new and useful Improvements in Needle-Tln'eaders, of which the following is a specification.

This invention relates to means for threading sewing-machine needles, and has for its object to provide improved means of this character in the nature of an attachment for con venient application to the stationary arm of any ordinary sewing-machine in position for convenient manipulation to facilitate the threading of the needle. It is furthermore designed to provide for conveniently applying and removing the device without changing or altering any part of the sewing-machine whatsoever and also to arrange for readily adjusting the device to an inoperative position when not in use, so as not to interfere with the ordinary manipulation of the sewing-machine, thereby obviating the necessity for entirely removing the attachment when not actually in use for threading the needle.

With these and other objects in view the present invention consists of the combination and arrangement of parts, as will be hereinafter more fullydescribed, shown in the accompanying drawings, and particularly point ed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a side elevation of a portion of a sewing-machine arm hav ing the device of the present invention applied thereto and shown in its initial threading position. ,Fig. 2 is a similar view showing the device adjusted to its final threading position. Fig. 3 is a detail perspective view of the attachment removed from the machine. Fig. 4 is a longitudinal sectional view thereof. Fig. 5 is a detail sectional view on the line 5 f Fig. 4:. Fig. 6 is a detail sectional view through the handle of the device to show the mounting of the thread-engaging hook.

Like characters of reference designate corresponding parts in each and every figure of the drawings.

The present embodiment of my invention consists of a body or bracket made up of front and rear platemembers 1 and 2, respectively, which are riveted or otherwise mutually connected. The inner face of one of the members, prefer-ably the member 2, is provided with an intermediate longitndinal groove or way 3, extending throughout theentire length of the member and open at opposite ends. The lower end of the bracket is' provided with a concaved socket or seat 4:, intersecting the lower end of the groove. At an intermediate point the front face of the front member 1 is provided with a transverse seat or recess 5. intersecting the opposite edges of the member and receiving a cross-bar 6, which is riveted or otherwise connected to the bracket and has its opposite ends projected beyond the bracket and provided with perforations 7 for the re ception of fastenings to secure the device in place, as will be hereinafter described.

Working in an endwise direction through the longitudinal groove or way 3 is an arm 8, which projects through the opposite ends of the way and preferably consists of a thin metallic and elastic strip capable of'sliding through the way and having a frictional engagement with the walls thereof sufficient to hold the strip or arm against the action of gravity, so as to prevent the same from dropping out of the bracket.

At the lower end of the flexible or elastic arm there is a handle 9 projected rearwardly from the arm and provided in its front end with a longitudinal socket 10 for the reception of the shank portion of a hook 11, which is held against displacement by means of a suitable set-screw l2, piercing the handle and engaging the shank of the hook.

For an understanding of the application and operation of the present invention reference is had to Figs. 1 and 2 of the drawings, wherein I have illustrated a portion 13 of any commen or ordinary sewing-1nachine arm, which carries in the usual manner the vertically-re: ciprocatory needle-bar 14:, to which is connected an ordinary needle 15. The bracket or body of the present device is applied to the rear or under side of the sewing-machine arm and is connected thereto by means of suitable screws, one of which has been indicated at 16, passing through the openings 7 of the ears formed by the opposite ends of the cross-bar 6. It will here be observed that the attaching-bracket is of convolute form, so as to fit in the angle between the horizontal and upright portions of the sewing-machine arm, and it will therefore be understood that the shape or form of the bracket may be considerably varied to accommodate it to the various forms of arms without departing from the spirit of the invention.

In using the present device the handle 9 is grasped and drawn downwardly, so as to pass the hook 11 through the eye of the needle, after which the thread 17 is engaged with the hook, and then the handle is drawn rearwardly, so as to withdraw the hook with the thread through the eye of the needle. It will now be understood that the 'arm 8 is flexible or elastic, so as to permit of the lateral movements necessary to pass the hook 11 through the eye of the needle and withdraw the same therefrom. Furthermore, the bill portion of the hook should stand upright or rise from the shank thereof in order that the thread may be conveniently engaged therewith merely by placing the same transversely across the upper side of the shank and then withdrawing the hook through the eye of the needle, whereby the thread will lie in the path of the hook and be carried therewith through the needleeye. When not in use, the arm is moved upwardly to its upper limit, with the front portion of the handle 9 and the hook lying within the seat or socket 4 in the lower end of the bracket, whereby the device is disposed so as not to interfere with the usual manipulation of the machine, and the hook is housed and protected against damage by accidental con tact with the sleeve or hand of the operator.

From the foregoing description it is apparent that the device of the present invention is very simple and inexpensive and is complete in itself. Moreover, it is in the nature of an attachment and is capable of application to the arm of any sewing-machine without requiring any change or alteration whatsoever in the arm or any other part of the machine and when in place does not interfere with the proper manipulation of the sewing-machine.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is

1. A needle-threader embodying an attaching-bracket having a way, an arm slidably mounted in the way and projected beyond one end of the bracket, said arm being flexible to permit lateral play of its projected portion, and a thread-engaging device carried by the projected portion of the arm and of a size and form to be entered through and withdrawn from the eye of a needle 2. A needle-threader embodying an attaching-bracket made up of a pair of members placed face to face, the contiguous face of one of the members being provided with an openended groove, an arm working in the groove with one end projected therefrom and flexible to permit lateral play thereof, and a threadengaging device carried by the projected portion of the arm.
