SPECIFICATION forming part of Letters Patent No. 606,269, dated June 28, 1898. Application filed une 9, 1897. Serial No. 640,084. N0 mo el) To all whom it may concern.-

Be it known that I, LOUISA J ANE BOWMAN, of Amoret, in the county of Bates and State of Missouri, have invented certain new and useful Improvements in Sewing Machine Threaders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object to provide a device for threading sewing-machine needles that can be quickly applied to the needle and will offer a guideway presenting a comparatively large opening through which the thread is passed and threaded through the eye of the needle, the said guide being open at one side and the body of the device provided with a corresponding open-ended slot to permit the said device to be removed from g the thread and needle.

The invention also contemplates a novel manner of holding the same in connection with the needle duringthe operation of threading.

With the above ends in view the invention consists in a device for threading sewing-ma-.

chine needles comprising a straight metal piece having a longitudinal groove terminating in a seat for the point of the needle and a guide presenting a tapered opening, the smaller end of which is so positioned with relation to the eye of the needle and seat for the point as to be on a line with said eye when the device is applied, the said device being held in proper engagement with the needle by magnetizing the same, all as hereinafter fully described, and particularly set forth in the appended claim.

In the accompanying drawings, forming part of this specification, Figure l is a View showing the application of my invention. Fig. 2 is an enlarged detail view of the threading device. Fig. 3 is a longitudinal sectional View. Fig. 4 is a transverse sectional view.

Referring more particularly to the drawings, the numeral 1 designates the body portion of the device, which is a metal bar or strip, in one side of which is a longitudinal groove 2, conforming to the size and shape of a sewing-machine needle, the said groove ter-,

minating near one end of the metal piece in a seat 3 to receive the point of the needle. In one side of the device is an open-ended slot 4;, terminating at its inner end on a line with the eye of the needle, and leading to the inner end of said slot is a funnel-shaped guide 5, the guide having a slit 6 coinciding with the 'slot.

It will be understood that the body portion of the device is comparatively small and not much larger than the needle to which it is applied, and in order to provide for readily attaching the same it is magnetized, by which force it is properly held against the needle. As the device is specially adapted for threading sewing-machine needles, I prefer to connect the same to a part of the machine by means of asmall chain, (designated by the numeral 7,) though it is apparent that it could be independent of the sewing-machine.

In the operation of the attachment hereinbefore described it is placed against the needle and moved so that the point of said needle will enter the seat or socket and bring the eye in proper alinement with the guide, after which the thread is passed into the enlarged end of the guide through the eye of the needle, after which the device is removed by bringing the thread through the opening of the guide and open-ended slot on a line with said opening.

It will be understood that in placing the device against the needle the magnetic force will be suiiicient to hold it in proper position, and this particular manner of holding the device in place provides for a ready attach mentand detachment. The projecting guide or flared tube forms a convenient handle by which the attachment can be manipulated in placing it into engagement with and removing it from the needle.

The device forms a very cheap, simple, and eifective means that will greatly facilitate the operation of threading aneedle, as the guide presents a comparatively large opening to receive the end of the thread and guide it to the eye.

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

I11 testimony whereof I have signed this specification'in the presence of two subscrib- 1o ing witnesses.

LOUISA JANE BOWMAN.
