IMPROVEMENT IN MACHINERY FOR MAKING CORDS OR BANDS.

Specication forming part of Letters Patent No. 118,408, dated August 22, 1871.

To all whom it may concern:

Be it known that we, THOMAS UNsWORTH, of Manchester, and EDWARD WHALLEY, of Preston, in the county of Lancaster, En gland, have invented a new Improvement in Machinery for Making Banding or Oord, and we do hereby declare the following, when taken in connection with the accompanyin g drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this speciication, and represents, n-

Fig'ure 1, a side elevation; Fig. 2, the reverse side 5 Fig. 3, an end View on line O D of Fig. 5; Fig. 4, an end view on line E F of same; and in Fig. 5, a plan at line A B of Fig. 2.

Our invention relates to an arrangement of machinery for twisting into bands or cords sewin g-cotton or thread from or out of cotton, woolen, hemp, linen, silk, or wire, or any other pliable material, mixed or separate, and so arranged that strands and bands are made on the same machine and at the same time, the strands being made and wound onto the bobbins, and without removing such bobbins from the machine the strands are passed across, doubled, and twisted into banding, cord, sewing-cotton, or thread, or any such like article.

In Fig. l, a is the frame; b, driving-drum, supported in frame c c c c c c are spindles, on which are keyed band speedpulleys d. On the same spindles, at center, are fixed iliers e. These fliers are used for unwinding the strands from bobbins f, giving such, if required, more twist in crossing the machine. These spindles are driven by drum b through pulleys d. In Fig. 2, a the frame, b the drum, as before. In this view are shown both arrangements for making strands and bands. The pulley 7L is driven from drumshaft by band z' to pulley j, giving motion to shaft m in Fig. 5. There are six spindles on this side, with six bobbins, driven in same way from drum b. The shaft n is driven by wheel z through wheel o, in Fig. 4.. In same figure the wheel l drives shaft m. In Fig. 5 the same wheel gives motion to shaft fn, through wheel o. The wheel l will 'have one tooth more in it. than wheel o, the obj ect being to run shaft u slightly quicker than m. On shaft n are keyed two rollers s". Two similar rollers are keyed on shaft m, marked s. s and t are a pair of flat-surfaced rollers, through which the yarn or other material passes from the cops a8 over cross-bar or guide a9 through such rollers to Eier-eye down the leg to bobbins f1. c is a moving rail, which is worked up and down during the process of winding on the bobbin, the fliers f2 putting the twist in the strands L L. The four first iiiers f2 are for twisting bands from the before-mentioned strands across the machine through the rollers s and s from the strand-bobbins taken from the two last-named iiiers to the other side of the machine. Such bobbins are marked j'. The shaft n, inFigs. 2 and 5, gives motion through wheel p, in Figs. 3 and 5, to wheel r on shaft q in the latter ligure. On such shaft the rollers s s are keyed. The two top rollers t t are driven from the friction of rollers s s at the end of shaft m. In Figs. 2, 3, and 5 is a miter-wheel, a, working into another imiter-wheel, o, giving motion to vertical shaft w, on which is a screw-worm, w, wheel y in Figs. 3 and 5. On the other end of spindle-carrying wheel y is a cam, which gives motion to connecting-rod a, in Fig. 8. In the same iigure c is a lever, one end of which communicates with connecting-rod a and the other end to bobbin-winding rail c1. There is another lever at the other end of bobbin-winding rail c2. These two levers work on a fulcrum-shaft, c3. The spindles cL are driven by bands from drum b to the several pulleys marked b1, b2, b3, b4, b5, and bG. On the spindles c4 are bobbinsj'1 and iiiers f2. al is a guide-bar, same as in Fig. l. a2 are screws with spiral or other springs acting on a brake or friction-pulley at the bottom end of bobbins f1. This eft'ectually winds the strands and bands rmly on the bobbins. In Figs. l, 2, and 3 are shown cop or vother board, al, on which we have shown by preference ran ges of cops a8, the threads from which are carried to guide-bars a9 over, down, and through another guide-bar, c6, at the back of rollers s and t, in Figs. 2 and 5; from thence through and round before-mentioned rollers to fliers in front of such rollers, marked f2, to bobbins f1. c7 is a guidebar, through which the strands pass from bobbins j'.

In making strands by our improved machine we take as many threads as required and pass them over the guide-bar a9 to the rollers s and t, round top rollers t, in order to stretch or lay the threads. They then pass from rollers's and t to the eye of the Eier f2, thence down the leg to the which slowly turns end, and so on to the bobbin. Thus the strands are made by the two right-hand spindles in Fig. 2. When such strand-bobbins are full they are removed to the opposite side of machine to spindle c. As many strands as required to make the cord or band are then taken and passed through holes provided in guide-bars c7 or c6, or both7 as required7 to the grooved rollers s and s, round both of which they pass. The rollers s revolve slightly quicker than s', Which brings it up tight to iers f2, Which twist the bands from the strands so passed. The fliers for twisting strands run in an opposite direction to those for bands7 thus having the usual effect of locking each twist.

lIaving` fully described our invention and the Way in which it is Worked7 We mayA say, in conclusion, that We'do not confine ourselves to the precise details We have had occasion to refer to7 pose specied.
