CORPORATION OF NEW JERSEY WIRE ROPE MAKING MACHINE AN'D METHOD Application filed May 15, 1931. Serial No. 537,518.

This invention rela-tes to machines for making wire rope or wire strand of that class in which a number of wire strands or Wires are wound helically, usually on a metal or hemp core, and relates especially to that part of the mechanism in which the strands or wires are laid up on the core and the rope or rope strand closed.

One of the principal objects of the invention is to provide an improved laying up and closing mechanism, in which a better control of the strands or wires shall be secured, so as to enable the production of a rope of eiractly the characteristics desired and maintain the strands or wires in the condition required for the best service and greatest durability of the rope under its service conditions.

A further object of the invention is to provide a simple and eficient method and mechanism for making dead lay wire rope or strand, that is, rope or strand that will lie without twisting or uncoiling at the end and to control the strands or wires so as to avoid objectionable torsion therein.

For a full understanding of the invention, a detailed description of a construction embodying all the features of the same in a preferred form will now be given in connection with the accompanying drawings forming a part of this specification, and the features forming the same then be specifically pointed out in the claims.

In the drawings, which show the invention applied to a wire rope machine of a common typ Figure 1 is a diagrammatic sectional elevation of the machine;

Figure 2 is an enlarged sectional elevation of the laying up and closing portion of the machine, the section being taken on the line 2 of Figure 3;

Figure 3 is a plan View looking downward on the line 3 of Figure 2;

Figure 4 is a plan view looking upward from line 4 of Figure 2.

In the following description and claims, the word wire will be used as including both i wire and its strands, and the word rope as including both rope formed of strands and strands formed of wires, the invention being equally applicable to both.

Referring to the drawings, the fiyer is shown as of common form, consisting of a rotating standard 10 carrying the spiders 11, in which are mounted the bobbin frames 12 carrying the bobbins 18, this iyer being shown as carrying at the top of the standard 10 the head 14 with the usual inclined guides 1 through which the outer wires m pass with the core y to the squeezer 15 held in fixed position by the supports 16 and from which the finished rope X passes to the usual drawoff roll 17 and around guide roll 18 to the wind-up reel. The fiyer and bobbin frames are shown as driven by the usual planetar gearing from the driving shaft 19, whic drives the fiyer through gears 20, 21 and the bobbin frames through gears 22, 23, 24, 25, so that the bobbin frames are rotated reversely during their revolution with the flyer, this reverse rotation being about one rotation to each revolution of the flyer and acting to prevent or regulate the torsion on the individual wires as usual in such machines. Any othei` suitable mounting and driving means for securing the required movement of the fiyer and bobbin frames may be used, with the bobbin frames mounted either oli' center or axially relatively to the flyer as common in the art.

Referring now to the parts added to the machine above described for the embodiment of the present invention, ais a stationary support fixed on the top of fiyer head 14, in which is mounted to rotate, as on ball bearings 2, a series of hollow nozzle carriers b, one for each wire each of which carriers b carries a nozzle c through which the wire m passes from the flyer to the laying up point. The nozzles are set at one side of the normal path of the wires from the flyer head guides 1 so as to bend the wires in their passage from the guides 1 to the laying up point, the angle of their bend and the distance from the nozzles to the closing point being fixed in accordance with the characteristics desired in the rope. The nozzle carriers b are geared to an internal gear d surrounding the series of carriers, the outer side of the internal gear being formed with sprocket teeth and driven at the proper speed by sprocket chains e from shaft f, which may be driven by any suitable lneans, either from the main shaft 19 or the pull-off device, or by separate motor. These nozzles will be rotated in the direction opposite to the rotation of the head.

From the nozzles c the wires pass to a die g which, as preferable and shown in Figure4, is separate from the squeezer and mounted to rotate. As shown, this die g is a split die held in a split dog h secured to hold the die by pins 3 and driven to rotate from wheel j, the outer rim of which is formed with sprocket teeth and driven by sprocket chain lc from shaft l, or otherwise so as to be driven at the desired speed and in the desired direction independently of nozzles c. The die g is mounted directly below and close to the squeezer 15 and rotates on bearing plate 4 between the squeezer and nozzle. This die g is curved on its entering Sides so as to guide and bend the wires properly for laying upon the core in the manner desired and is formed with a small clearance for the wires and rope so as to allow the wires to position themselves readily in laying up.

In making dead lay rope, the nozzles c and die g will be positioned relatively to each other, both in respect to horizontal and vertical dimensions, so that the helices formed in the wires as they are laid up on the core, will be permanent helices and avoid the tendency of the wires to untwist, as they do in the usual process of laying up the wires on to the core. For this purpose the wires must be bent at suitable angles in passing over the nozzles c and the die g and the machine run at suitable speed, the angle and speed being determined by the lay of the helices desired in the complete rope or strand. It will be understood, however, that the nozzles and die may be so arranged as not to make the dead lay rope, but only control the Wires to secure the characteristics desired in the finished rope.

In thus laying up the wires and closing the rope, there isa tendency to twisting or torsion of the wires, and for the purpose of controlling this twisting or torsion, either to avoid it so as to produce a wholly neutral rope, or to provide rope with some twisting or torsion in either direction, according to the characteristics required in the rope, the nozzle c and die g preferably are both positively rotated, as shown, the surface movement of the rotating nozzles and die relatively to the rotation of the fiyer head 14 being arranged to fully avoid the twisting or torsion tendency of the wires or to control this in the manner desired. For the avoidance or reduction of this torsion, the nozzles c and die g will be rotated in the direction opposite that in which the wires tend to twist, but under some conditions. it may be desirable to rota-te the nozzles and die, or one of these, in the same direction as the wires tend to twist, this depending on the torsional characteristics required in the rope. It the same machine is to be used for rope differing in characteristics, the nozzle c and die q will be made adjustable relatively to each other and provided with means for varying their surface speed of rotation, but the same result may be secured by making a special head for each rope differing sufiiciently in characteristics to require this.

Under some conditions, it is possible to omit the positive :rotation of the nozzles and die and leave them free to rotate under the pressure of the wires, and in some cases the die g may be fixed in position, but usually and especially in making dead lay rope, with the angle of the wires in passing from the flyer head nozzles that is required for that purpose, as shown, it is much preferable that both the nozzles c and the die g should be positively rotated. It the die g is not mounted to rotate, it will be understood that it may be formed as the entering part of the squeezer and either integral with the squeezer or attached thereto.

It will be understood that the invention is not limited to the exact construction or arrangement of parts shown, but that many modifications may be made therein while re'- taining the invention defined by the claims.
