IMPROVEMENT IN MACHINES FOR MAKING COVERED CORD."

Specification forming part of Letters Patent No. 38,190, dated April 14, 1863; Reissue No. 3,345, dated March 30, 1869. I

To azz whom it may concern:

Be it known that we, Jenn TURNER, of.

Norwich,'in'the county of New London and State of Connecticut, and Isnno E. PALMER, of Montville, same county and State, have invented an Improvement in Machinery for Manufiicturing Covered Twist and Cord, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- I Figure 1 represents a vertical section of a machine for making covered cord. Fig. 2 is a horizontal section of 16831116 above theupper series of bobbins. Fig. 3 is a sectional elevation of oueof the strand-spindles, and Fig. 4 a top view of the same.

Similar letters of reference indicate corresponding parts throughout the several figures.

This invention consists in a novel combination and arrangement of mechanism for producing covered twist or cord; also embraces such a relative travel or action of devices as that the covering or finishing material is laid in a converse direction to the twist imparted to the respective strands.

Referring, in the firstinstance, to Figs. 1 and 2 of t 1e drawings, chine. having arranged-say in the center of it-atn upright main rotating spindle, B, in its lower part a horizontal shaft, from which said spindle is shown as deriving rotary motion through a pair of bevel-gears. F F and G G are the strand-spindles, of which there may-be any desired number, the same being carried by or operating in connection with and arranged parallel to and at equal distances apart from the main spindle B. The lower ones, I? F, of these spindles carry the bobbins H H, which supply the yarn or thread to make thcbody of the twist of which the strands are to becomposed, and the npperones, G G, carry the bobbins I l, which supply the covering yarn or thread. The lower spindles, F

. F, are shown as fitted to bearings in arms I I and J J, which are firmly secured to the main spindle 13, while the upper spindles, G G, which; are made hollow, may be fitted to ro- A is the frame of the ma-.

'ive axes in an tate upon the upper parts of their respective spindles F F, and supportedvby the upper arms, J J, of the main shaft. G must be-coincident or in line with the axes of the spindles F F. ,The upper parts of the spindles F F are also hollow down to a point below the arms J J, and an opening, a, lead- 'ing into the interior of the said hollow portion of each, is provided through the side. of the spindle. The several bobbins H are shown as fitted to turn easily upon upright spindles 11, secured in disks H H, which are fast upon their respective spindles F F, and the several bobbins I I are fitted to turn easily upon spindles i 13, secured in disks 1 upon their respective spindles G G.

The lower portions, b b, of the disks H may, if desired, be made in the form of pulleys, to work in contact with the inner periphery of a fixed ring, K, secured to the framing, and for the purpose of obtaining a rotary motion of the spindles F F on their respective axes, through the agency of the friction produced between the said portions b 1) against the said ring in the revolution of the spindles-F Fabout the axis of the main spindle B; also the lower portions of the spindles G G may be made with pulleylike hubs c c, to'work in contact with the inner periphery of a fixed ring, L, in the same manner as b b work in contact with K, for the purpose of producing the rotation of the spindles G on their respectopposite direction to the retary motion of the main spindle by their planetary revolution about the axis of the spindle. The outer peripheries of c c and b I), or the inner peripheries-of K and L, inay'be faced with leather, india-rubbcr, or other material by which a suitable degree of friction to produce the rotation of the strand-spindles on their respective axes maybe obtained. Of

course gear of any suitable kind may be substituted for the frictional arrangement or devices described, to give to the strand-spindles F and G their specified motions. The rotation of the spindles G G is in the same direction as that of F F; but the spindles G G rotate at a higher velocity th an F F, and which difference in speeds is here shown as accom- The spindlesG I I, provided spindle, the said eye conducting them to theopening a.

ff are guide-pins secured in the disks 1 I, for conducting the several yarns or threads from the bobbins I I to openings g g, provided in the upper parts of the spindles G.

M M are a number of arms corresponding with the number of the spindles F F, and of those G G, firmly secured to the main spindle B above the spindles G G, and containing holes to guidethe several strands from the latter spindle to the holes 9' j, which are here shown as provided in the upper part of the spindle B, to constitute what is termed in cordagc-maehines the filaying top.

P Q is an apparatus arranged on the top of the frame A, for taking up the cord as fast as it is made. This is substantiallylike the apparatus commonly used in rope-machines for taking up the finished rope, and derives motion through gearing from-the main spindle B.

On setting the machine in operation, the spindles F F twist together the yarns from the bobbins. H H, the said yarns passing through the spindles G G, as well as through the upper parts of F F, and the twist taking place between the openings at a and the holes in the arms M M, and just before their twist is quite completed, or thereabout, the strands receive the yarns from the bobbins I I, and,

owing to the increased velocity of the spindles G G as compared with F F, the said yarns are wound upon and made to cover the exteriors of the strands before, say, the latter pass the guide-arms M M, which conduct them to the laying top, to be twisted together between the said top and the take-up apparatus by the rota'ry motion ofthe main spindle.

- The machine represented in Figs. 1 and 2 has three sets of strandspindles and bobbins for making three straud cord, but the number of sets may be varied to make cord with a different number ofstrands.

\Vhen it is desired to make covered twist without manufacturing the twist into cord, a single spindle, F, and a single spindle, G, and their appendages, combined as abovespecified, and shown in Figs. 3 and 4, may be so arranged and operated that the said spindles have simply arotary motion about their own axes, and the covered twist will be produced in the same manner as has herein been described in the covering of the strands,

, The covered twist and cord .may be produced by making the upper spindles,G G, rotate in an opposite direction to the spindles F F, which mode of operation is embraced in this invention, and the means for aceomplishing such reversed driving action need no de' scription here, as the same, uuderdiflerent modifications, will readily suggest themselves to any mechanic of ordinary skill familiar with nfihinery for the manufacture of twist -or cord. .1 have, however, represented in cle vation in Fig. 5 of the drawings a simple modification of themachine'shown in Figs. 1.

and 2,whereby this method of driving the upper spindles is effected. The upper frictionriug is dispensed with and the. pulleys c c of" the upper spindles are all encircled and drivenby a crossedband,V, which runs on a pulley, c,

on a spindle, S, which is geared bytwo spurgears, T and U, with the main spindle B.

Under such a method .of manufacturing covered cord it will be seen that the covering is necessarily laid in a converse direction to the twist imparted to the respective strands of which the cord is formed, and whereby the covering yarns or threads are restrained from working in between the twists of thestrands,

anda more perfect covering is obtained with less covering material.

Although the spindles G G,instead of being fitted to rotate upon FF,may be entirely separated from them, it is important that they should be arranged with the axis of each spindle G in line with that of its respective spindle F, and thespindles G should in all cases bemade hollow to admit of the passage of thetwists or strands through them. By the divided arrangement of theholes or openingsgg in the upper parts of the spindles G, and which holes in each spindle should lie in'precisely the same horizontal liric or plane, the covering-cords as passedor received from the several guiding-pins f f are prevented from fouling, and regularity and smoothness insured in the laying of the covering.

W'hat is here claimed, and desired to be secured by Letters'Patent, is- 1. The arrangement of the main or laying spindle, the strand-spindles, and'the hollow spindles which carry the covering-bobbins, as

herein described-that is to say, the said hollow spindles having their axes in line with the axes of their respective strand-spindles, and, arranged around the line of the axis of the main or laying spindle, substantially as 4 'herein set forth.

2. The combination,with the spindles F and their disks H and bobbins H, of the hollow spindles G and their disks 1 and bobbins I, the latter spindles, disks, and bobbins revolving independently of the former, substantially as and for the purpose herein shown and described.

3. The combination,with the spindlesF at M .G, of the holes or openings 9 9, arranged, sub- .stantlally as described, in the spindles G for operation in concert with guiding-pins ff to the yarns or threads from the bobbins rotated by the spindles G, substantially as describeds 4'.
