To all whom t may concern.'
Beit known that I, JOHN SLACK, residing at Brooklyn, in the county of Kings and State of New York, a subject under the. crown of Great Britain, have invented an 4Improved Needle and Shuttle Threader and Knife combined, of which the following is a specification:
This invention has for its object to combine into a single instrument several of the more important implements which are employed in the manipulation and operation of a sewingmachine. It combines a needle threader, a
disentangler, a shuttle-lifter, and a knife. The
invention consistsin a peculiarly-shaped blade, curved at its termination, and running out into a hook. This blade is attached to a suitable handle, which may also be provided with a spring clasp for retaining the thread while threading the needle. Either the blade or the clasp, or both, may be sharpened at either or both of their sides, so that they may be used as knives. With the hook the thread may be easily disentangled, and by the same means the shuttle lifted out of its place, and the needle as well as the shuttle threaded.
Figure l in the drawing is a side view of my improved implement, showing it combined with the spring-clasp. Fig. 2 is a side view of a modification of the same. Fig. 3 is a section through the line c c of the blade of Fig. l. Fig. 4 is a section through the line 7c k of the blade of Fig. 2.
Similar letters of reference indicate corresponding parts in all the gures.
The letter A represents-the handle of my instrument. B is the blade, which is bent into a hook, a, as shown in Fig. 1.
This instrument is specially adapted for use in sewing-machines not provided with a shuttle, it being then employed to disentangle the thread, or to thread the hook or needle, as well as to serve as a knife for cutting the thread, 85o.
. The modification of my instrument represented in Fig. 2,-is intended to be employed in a sewing-machine provided with a shuttle.
The blade B is then curved so that it may be entered beneath the shuttle to lift it out of its place, while the hook a serves for the same A
