ANDREW S. HALLIDIE, OF SAN FRANCISCO, CALIFORNIA.

WlRE-ROPE-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 369,055, dated August 30, 1887.

' Application filed June 20, 1884.

To all whom, it may concern.-

Be it known that I, ANDREWS. HALLIDIE, of the city and county of San Francisco, State of California, have invented an Improvement in Wire-Rope-Making Machines; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an apparatus for the manufacture of strands such as are employed in the making of flexible wire rope, these strands consisting of a central core around which six wires are laid, forming a strandcore, and twelveother wires are again laid around this strand-core, thus completing a strand. These strands,after being completed, are laid up in a rope by means of an apparatus having a suitable laying-head, so that when completed the entire rope would consist of one hundred and fourteen wires, each strand consisting of nineteen. These strands have hithereto been laid up by first forming the strand-core in one machine and then taking this core and passing it through a second machine, so as to lay around it the twelve wires which complete the strand.

My invention consists of an apparatus in' which a machine for forming the strand-core and a machine for laying the exterior wires around the strand-core are combined in one with an intermediate device whereby the strand-core is carried into and through the second portion of the apparatus and thence delivered through the laying-head of the same to be covered with the twelve wires without being spirally twisted by the revolutions of the machine.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a plan view of my apparatus. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged side sectional elevation of a portion of the apparatus. Fig. 4 is an enlarged transverse section taken through line X X of Fi 3.

is the frame-work, fixed upon a suitable base or floor and having supported in it the longitudinal revolving frames A and B, having disks A B fixed atintervals to the longi tudinal rods or bars A B. These disks are 3 and 4, which are journaled in the station Serial No. 135,546. (No model.)

ary frame and press upon the peripheries of the disks, so as to steady the rotary frames in their revolutions, and the whole frame-work is rotated by suitable devices, hereinafter re ferred to. Between the disks of the longitudinal revolving frames are supported the bobbins a, upon which the wire to form the strand-core is wound. These bobbins are journalecl with their shafts standing transversely in frames at, which frames have their longitudinal axes journaled centrally between the supporting-disks, and the bobbin-frames are weighted, so that as the frames A B are revolved the bobbins will remain stationary.

The wire from each bobbin in the frame B is led through the center of the disk in front of it, passing thence'to the outside of the frame over guiding-pulleys b, and is carried forward to the laying-head J. The strand-core is thus formed in passing these wires through the laying-head J,and frointhis point is carried over the pulleys H and I, by which it is led back to the rear ofthe apparatus.

The second longitudinal revolving framework,A, is provided with bobbins and devices, hereinafter referred to, by which it is rotated in unison with the firstdescribed apparatus and at the proper relative speed, so as to lay the wires from its bobbins around the strandcore previously formed. This second mechanism contains twelve bobbins journaled and supported in the same manner as previously described, and the wires from these bobbins are led forward, so as to pass through the laying head or plate N of the machine A.

The strand-core which was formed in the portion B of the apparatus, after passing around the pulley I, is directed through the hollow spindle K at the rear end of the portion A of the apparatus. After passing through this spindle it is carried to the outside of the revolving frame of A by means of a curved guide, M. This guide consists of two semitubular sections, which are bent and united so as to form a reverse curve, as shown plainly in Fig. 5. The strand is carried through this curve to the outside of the revolving frame, and thence is carried along the guide-pulleys to the front end of the machine, where it again passes through another similar guide, l formed of curved semi-tubular sections united ICQ in the same manner. This second guide delivers the strand-core through the laying head or plate N of the second portion of the apparatus, and the wires from the bobbins of this second portion are rotated around the strandeore in this laying-head, thus completing the strand.

The two portions of the apparatus are united by operating devices, which may be in any suitable form. As shown in Fig. 2, a shaft, D, is journaled in hangers and provided with fast and loose pulleys at either end, as at 1 2. Motion from these pulleys is transmitted to the frames through belts 3 4 and pulleys 5 6, carried by the frames. It will be understood that this form is shown for convenience, and any equivalent means may be employed, as desired. Thus, as shown at 8, 9, and 10, a train of gearing may be used between the two portions. The two portions are thereby driven at a proper speed with relation to each other. This insures the twelve wires being laid around the strandcore in the proper spiral, so as not to cross the wires of the strand-core. By attaehing a third revolving frame provided with eighteen or less bobbins the same process can go on and a third layer of eighteen or less wires can be laid around two layers, and a strand is then formed with three layers of untwisted wires around a central wire or core.

By means of the reverse curves M M, through which the strand-core is carried in passing into and out of the second portion of the apparatus, this core is prevented from being spirally twisted or kinked by the revolutions of the machine as it enters and passes out through the hollow spindles.

The two portions of the machine being built in the same supporting frame-work, and having the driving gears or pulleys by which they are driven simultaneously, form a continuous apparatus by which the strands are completed and ready to lay up into rope.

I am aware that a single machine carrying seven bobbins has been employed for making strand-cores, and that other single machines of twelve bobbins have been employed to lay twelve wires around a strand-core which has been completed in a separate machine, and I do not claim, broadly, either of these construetions; but,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A series of independent revolving bobbin carrying frames with the intermediate driving mechanisms, in combination with guiding sheaves or pulleys, by which the strand-core formed in one frame of the series is carried to the rear portion of the second and delivered centrally through the hollow spindle of the same, substantially as herein-described.

2. In combination with the central hollow spindle and the revolving frame, the reverselycurved guides extending from said spindle to the exterior of the revolving frame, substantially as described.

In witness whereof I have hereunto set my hand.

ANDREW s. IIALLIDIE.
