MAC-HlNE FOR MAKING WIRE ROPE.

SPECIPICATEON forming part of Letters Patent No. 366,422, dated July l2, 1887.

Application filed February 10, 1886.

To all whom, it may concern:

Beit known that I, ROBERT STIRLING NEW- ALL,of the borough of Gateshead,in the county of Durham, England, have invented certain new and useful Improvements in Machines for Making Vire Ropes, of which the 'following is a specification, reference being had to the drawings forming part thereof, in which- Figurelisasideview ofthe machine. Fig.2is an end view of the front bearing-wheels and frame. Fig. 3 is a plan of the drawing-gear and the forward end ofthe twisting-machine. Fig. 4. is a plan View of a piece ofthe completed rope. Fig. 5 represents one ofthe strands; and Fig. 6 shows a detail sectional view ofthe forward end of one ofthe bobbin-frames and the guide o and nozzle w, the forward end of the main shaft and the layingplate being also shown, and a detail View incross-section of the forward end of the bottom frame.

The invent-ion will be first described, and then pointed out in the claims.

c is the main shaft of the machine, which has a hole through it for the core of the rope to pass through. It has fixed on it at right angles the drivin g-wheel ai, Worked by motive power, the back arms, b, andthe front arms, c, each having six or other required number of bearings for supporting the strand-frames A, which rotate in the bearings iii the arms b and c. Each frame is constructed to hold the number of bobbins A', each containing a separate wire, A?, necessary to make a strand, A, and one bobbin containing the core At, which may be made of wire or hemp or other material.

In the top part of Fig. 1 the strandframe A is in side elevation, showing the three central bobbins, which are shown in plan at the bottom ofthe said figure. At the backs ofthe mai ii arms b there are wheels for causing the strand frames to rotate backwardly in their bearings once for each revolution they make round the axis of shaft a. These consist of a bevel-wheel, b', xed ou the end of each bobbinframe, and awheel, b2, of the same size, fixed to the supporting-pillar a', through which the main shaft a works. Two pinions, b3, of equal size, are fixed on each sha-ft 1f, and communicate inotion to the frame-wheels by being carried round the fixed wheel, and thus the torsion of Serial No. 191,452. (No model.) Patented in England April13,l885, No. 4,559.

the wires and the strands is prevented while they are being laid into a rope. The front arms, o, form awheel, C, which rotates on two other wheels, d and e, supported in a frame,O,

forming the front bearing of the machine, as u shown in Fig. 2. These three wheels are V- grooved on the surface, so as to have more adhesion between C and d, and at the same time to prevent the machine being drawn toward the drawing-gear. There is fixed on the outer end of the axle of the wheeld, Fig. l, atoothed wheel, f, which works into another wheel, g, which .is supported by a swinging link, g', hanging from the axle d', and working concentrically with the wheelf, so as to be always in gear with it.

h is one of a set of change-wheels of diferent diameters proportional to a gear-wheel, i, by means of which the draw is regulated. The change-wheels h slip on a tube or sleeve, one end of which is fixed in wheel' g, so that wheels g and 7i rotate together on a pin projecting from the swing-link g', and as Wheel 7L gears into z' the required speed is given to the wheel i, which is fixed on the shaft i', which carries at the other end the bevel-wheel j, working into another bevelwheel, k, on the axle of which is fixed the toothed wheel Z, which works into the wheel m, fixed on the side of the drawing-drum m, as shown in the drawings. There are two bevel-wheels 7c, one on each side of n, so that by pushing one into gear with a and pushing the other out either right or left hand ropes are made. These wheels k have setscrews passed through their hubs for holding them when adjusted on their shaft.

On the bed-plate which supports the front bearings there are also fixed four upright pillars, O2, which carry the four drawing-rollers D and drum m and wheelsnp 1' u o q s t. On the two lower shafts are fixed two toothed wheels, a p, which gear into wheel m, and on the same lower shafts, and under the wheels o' a, are fixed two other wheels, o q, which gear into wheels o' u, and these into wheels s i, which are fixed ou the upper shafts. On the four shafts which carry the wheels 1 s tu there are grooved drawing-rollers D,which are capable of sliding along the shafts on keys letinto IOO the shafts, so as to couple the shafts. and rollers together, and so as to bring the propersized grooves in a line with the axis ofthe main shaft a. These rollers grip the rope, and by the rotation of the machine and the action of the wheels described they draw off from the bobbins a certain lengt-h of wire-for i each rotation of the machine, and so form a rope composed of strands of wires A3, which strands are not subjected to torsion, as is usual in rope-making; but the rope may be drawn by taking several turns of it round the drum without using the rollers, or it may be drawn by the combined action of rollers and drum, for they both go at the same surface-speed.

The wires from the bobbins pass through the front journal of the strand-frame, where they are symmetrically arranged round a core, and they also separately pass through the guides v and nozzles '10, which project from each frame, and which rotate in the plate a'. The bobbin-frames are tubular at their forward or inner ends, and the cores from the several bobbin-frames pass entirely through these tubular ends, while the several wires enter said tubular portions and pass outward therefrom through six apertures, 1.

The guides v are formed of plates secured to or formed on the said tubular portions and having in the present instance six apertures, through which the wires pass from the apertures 1. The nozzles w are also provided with six apertures to receive lthe wires from the guides o and are screw-threaded to engage screw-threads on the extreme ends of the tubular portions of the said bobbin-frames, as

clearly shown in Fig. 6, and these nozzles rest in bearings in the plate x, so that they form the journals of the inner ends of the tubular portions of the bobbin-frames. The wires from each strand-frame being thus kept separate and without being subjected to torsion, are laid in separate strands or sets round a core into a ropewithout being laid or twisted together in the usual way of making wire rope.

I have illustrated the description of my invention by drawings of a machine in which the main shaft is horizontal, which I prefer to having the main shaft perpendicular; but my improvement is easily applied to a perpendicular machine so long as the strand-frames make one rotation on their axes while the inachine rotates once.

The drawings show a machine for making ropes of six strands, each strand having six wires and a core; but machines may be made having any other number of wires, cores, and strands. d 4
