    • 9148. McCarthy, J. W. May 17. Hand tools for use by the attendant upon any textile machine in which the ends of yarns or threads are required to be tied together. A piece of metal, which is slotted at one end to form two arms 1, 2 and is provided with a tongue 3 at the other, is folded upon itself so that the tongue 3 may be pressed against the arms 1, 2. The instrument is held in the manner shown, and the ends to be knotted are passed round the back, then round the front, again round the back, beneath the second finger by which the instrument is held, round to the front beneath the thumb and through the slot as shown. The threads are then gripped between the tongue 3 and arm 2 and the ends broken off close to the point where they are held. The loop at the back of the instrument is then passed over the upper end thereof and the knot is drawn tight while the broken ends of the threads are held firmly by the instrument. The completed knot is shown in Fig. 10. Instead of a single folded plate, two plates suitably connected together by a spring may be employed.
