' The Schedule refereed to in these Letten 4Patent: andmaking part of the same.

Tc all 'whom it may concern Be it known that I, JOHN TURNER, of Norwich, in the county of New London, and State of Connecticut,

have invented a newand useful Improveinentin Maaccording to my invention.

'Figure 2 ,is a horizontal section of the same, in the planeindicated by the line a; a: in iig. 1.

Similar'letters oreference indicate corresponding .parts in both figures.

This invention consists in'a'novel combination of l.strand-carrying devices whichdo not twist the strands,

strandfcovering devices, and a laying-device, whereby fa number of strands isviirst covered, and afterward laid together into a oord. Y

By this combination, several important advantages are obtained over those inachinesgin which the strands are twisted, covered, and laid at the same time, among which may be mentioned-#- First, the use, for the stra-nds, of a cheaper material, siich as hemp, which cannot be spun or twisted at the'same time that the covering is performed;

Secondly, the covering and laying of a greater length of cord, without lstopping to piece-np, owing to the greater quantity bf the strand, or body-material, which can be worked in the machine at one ltime;

Thirdly, the reduction of' the compass of the ma chine, by dispensing with the strand-twisting devices;

Fourthly, the provision made for the covering of strands of wire, and laying them into a cord.

To enable others skilled in the art to make and use my invention, I -will proceed to describe the example of it represented in the drawings.

A. is the frame of the machine, in the centre of which is arranged, inv suitable bearings, the upright laying-spindle B, whicbhas rotary motion imparted to it, bybevel-gears a b, from the horizontal driving-shaft C, arranged in bearings -iu the lower part of the framing.

The upper part of this spindle is constructed with a laying-top, d, like that of an ordinary cordage-machine.

VUpon the lower part of the laying-spindle there is rigidly secured a disk, D, in which is iirmly secured a number of spindles, E E, corresponding with the number oi-strands to be made into the cord, arranged parallel with theo 1 aying-spindle;` and between these spindles there is firmlyA secured, into tbe said disk, a corresponding number of smaller and shorter spindles,

c e, uponfwbich are placed loosely the rbobbins F F,

which carry the twine,g, or wire of which the strands are to be composed.

Some distance above the bobbins F F, there is secured-firmly upon the laying-spindle a disk, G, and to thisdisk there is firmly secured a number of upright hollow studs, c, which are so arranged and constructed that the spindles E E pass through, fit, and are held steady by them.

The exteriors of the said studs are turned to fit the central bores of the base-plates H H, of the hollow upright covering-spindles I I, which correspond in number with the strands, and which rotate about their respective spindles E E.

These base-plates have each firmly secured in ita number of spindles, ff, upon which are arranged, one upon each, the bobbins J J, which carry the silk or worsted with which the strands are to be covered, and which is represented in red color.

Between the covering-bobbins there are secured to the base-plates H, of the hollow covering-spindles, upright guide-pins l l, to guide the covering-material from its b obbin.

In the sides of the upper parts of the hollow covering-spindles I I, there are holes, corresponding with the number of bobbins, J J, on each, for the passage of the covering-threads to the strands; and above each of the coveringspindles there is arranged a guide, fi,

secured to the laying-spindle, for the purpose of con-` ducting the'covered strands to the laying-top d.

rIhe spindles E E h ave each, about opposite the middle of the length of the bobbins F F, a hole, h, made transversely through it, to serve as a guide for the strand, coming from its respective strand-bobbin F.

The upper parts of the spindles E E, commencing below the studs e, are hollow, and there is a hole, j, in one side of each, communicating with the internal cavity.

Belowand attached to the base-plates H, of the hol` low covering-spindles, there are pulleys L L, the peripheries of which are covered with India rubber or other soft *.material, and are in contact with the interior of a stationary ring, M, which is concentric with th'e'main spindle.

The friction of these pulleys against the said ring M, caused by the rotation of the laying-spindle B, produces the rotation of each covering-spindle upon its axis, as it revolves with and around the laying-spindle.

Above the laying-spindle there is a take-up apparatos, which may be like that common to cordage-v machines.

I will remark that this machine resembles that described for the same purpose, in the patent to myself and I. E. Palmer', issued April 14, 1863, except that the spindles E E are fixed relatively to the layingspindle, instead of rotating upon their own axes, and, instead of having strand-twisting apparatus, it has simply the bobbins F F, for carrying the strand-ma.- terial.

The operation is as follows:

The machine being set in motion, the strand-material, which may be either common hardware-twine, or any twine made for the purpose or otherwise, or wire, is unwound from the spools F, and drawn, by the action of the takeup apparatus, through the guide-holes h audj, aud through the hollow upper parts of the spindles E E, through the guides i i, and through the lay'llng-top d, above which they are laid together into co The separate strands g, as they pass through the upper parts of the hollow covering-spindles, receive the covering which is wound upon them by the rotary motion ofthe covering-spindles around them.

'I do not confine myself to the precise construction of the machine herein described; but

What I claim as my invention, and desire to secure by Letters Patent, is
