To all whom it may concern: y

Beit known that I, F. A. `,VVISWELL a citizen of the Dominion of Canada, residingat Beebe Plain, in the county of Stanstead and Province of Quebec, Canada, have invented certain new and useful Improvements in Art,

of Manufacturing Wire Rope; and I do hereby declare the following to be a full, clear, and` exact description of the invention, such as will enableothers skilled in theart to which it ap pertains to make and use the same.

This invention relates tothe art of manufacturing wire rope and cables, and has for its purpose,first, the strain applied thereto will be borne by all the wires composing the same; and, secondly, to `obtain a cheaper andsuperior workin g rope. To effect these results` I lay individual wires around cores to form strand-cores; secondly,

layindividual wires around the strand-cores to form strands; and, lastly, lay the strands around a main or rope coreto form the rope, lall in one continuous operation.

Fora full understanding of my improvement,

n reference is made to the following description and claims.

Referring to the drawings, Figure 1, Sheet l, represents a plan view of amachine adapted to carry out my improvedprocess, in which some of the parts are broken away and others removed to more clearly illustrate the principal working portion of the same. Fig.2,Sheet 2, is a front elevation of one of. the general n heads or groups of mechanism with a number of the spool-carriers removed and the arm g broken away. Fig. 3 is a longitudinal vertical section thereof, taken on the line ac oc, Fig.

` l 2. Fig. 4 is an end view ot' one ofthe spoolcarriers. Fig. 5 is a similar view, illustrating the end opposite to that shown in Fig. 4. Fig. Gis a front elevation, partly in section, of a spool-carrier. Fig. 7, Sheet 3, is an enlarged sectional view of the strand-laying-head mechanism. Fig. Sis an elevation of the slotted sector which `supports the gear Y, located between the driving and vmain shafts;` and Fig. 9 is a transverse section of a hoisting-rope.

Corresponding parts in the several figures are indicated by similar characters of reference. In the accompanying' drawings, A marks a `may be of any known to obtain a rope or cable in which anism, and .B the central hollow shaft, supported at its rear end in bearings d a', secured tothe frame A, and at its forward end in the rope-laying head C, which is held in bearings a? to said frame A. This rope-laying head G form or construction suitable for the purpose, though I have shown that form which is fully described in an application tiled by me July 1l, 1882, numbered 66,359, to which reference is made.

Two hubs, D Gr, are secured tothe main shaft Bat a suitable distance apart, and are respectively providedV with six radiating arms, d g, `whose extremities support six general heads `or groups of mechanism, which are designed to manufacture the strandcores and strands, and since said heads are alike in construction and operation, I contine myself to a specilic description ot' one ot' them, as illustrated in Figs. 2 and 3 of Ithe drawings. Referring, then, to said figures, d marks one of the arms of the hub D, partly broken away and having-the sleeve d secured toits end, said sleeve receiving and supporting the hollow shaft c. Secured with a set-screw, e', to'the hollow shaft c, in front of the sleeve d', isthe head E, provided with a number of arms, c2, projecting from its rim, said arms designed to receive the spool-carriers to be presently described. -Secured to the head E, opposite each other, are two arms, F F', which project forward and inward, and at the extremity of the shorter arm, F', form an annular bearing,f3, (shown in Fig. 1,) for the st-rand-corellaying head, which will be presently set forth. The outer arm, F, extends forward of the strand-corelaying head and ends in the hub f, which has a rim,f, connected to said hub by means of the spokes f2, (shown in Fig. 2,) the said arm F, hubf, rim f', and spokes f2 formed, in the present in stance, in one piece. The rim f has a bearingin the end of the arm g, as shown. The base H of the strandlaying head is screwed into the hub f, and is curved and tapered, as shown, to receive the sleeve l1., which has its inner surface curved in such manner as to fit the curved surface of the base, as more fully indicated in Fig. 7. rDhe sleeve h is held onv the base H by means of the tube I, which IOO operation of parts and the fact that said parts containing wire-bearing spools. Formed in one piece with the hub of the disk K, and extending forward therefrom in a curved manner, as shown, is an'arm, L, which ends in the hub l and rim l, formed in one piece therewith, said parts supporting the strand-core-laying head com posed of the curved base M, sleeve m, spider N, slotted tube m, set-screw m2, thumb-nut n, and coiled spring n, all of which are constructed in manner similar to the parts composing the strand-laying head, with the single exception that the spider N has a less passes through base H and'rcceives at its forward end the spider J, which in turn bears against the sleeve h. The tube I receives a thumb-nut, i, at its rear end, which presses against a coiled spring, fi', encircling said tube between said thumb-nut and the end of the base H, as clearlyshown in Fig. 7. A set-screw, h,'passes partly through the base H and into -a slot, 2, in the tube I, to prevent a rotation of the tube, while permitting longitudinal motion thereof'.

the less number of wires used in the construetion of the strand-core. The strand-core-layin'g head has all the-capabilities incident to the strand-laying head, as described hereinbefore.

Referring to one of the spool-carriers illustrated in Figs. 4, 5, and 6 that the arms e2 of the strand-head E and the arms 7a2 of the disk K, O marks the base; 0, the rigid arm disposed at right angles to said base, 'and o the swinging arm pivoted to the opposite end thereof. Engaging with the pair of lugs o2, formed one on each side of the rigid arm o, is a friction-block, P, .held in frictional Contact withV the friction-wheel Q,journaled in the' upper end of the arm o by means of the spr'ingp, abutting against the adjusting-screw p', working in the lower part of saidarm o. Gast on thlefinner face of the friction-wheel is a corrugated or ribbed stud, q, which partly projects into the hub of thespool R, and by reason of the corrugations or ribs causes the spoiol and friction-wheel to'be revolved together when the spool'is rotated. ing, arm is provided at vits end with a smooth or, if desired, lcorrugated stud, q, workin g ou in Fig. 2, the spider J has a number of slots, j, in its periphery, tocontain each an individual wire, whereby entanglement of the wires with one another will be prevented and their proper laying into the strand facilitated. 1 I provide the concaved surface-in the base H andthe contiguous oonvexed surface in the sleeve L, to cause said base and sleeve and the spider J to act as a wire-straightener.

It will be seen by referring to Fig. 7, which shows sleeve h removed Afrom close con tact parts at three points-namely, against baseH at its largest diameter, againstthe central part ofthe curved surface ofthe sleeve h, and against the spider.J in one of its slots. Further, it will be observed that the portion of the curved surface of sleeve It 'against which bears is at a point below a right line drawn from the bearin g-poin ts of the base and spider. This construction is provided so that upon drawing the wire through the partsfit will be the spool-carrier by meansof the bent retaina strand. By this operation of parts all bends .ing-wire o3, which is passed around the swingor curves that may be in the wire as it leaves a spool will be removed, and the curvature or bend given to it by the described mechanism said arm, and has its ends secured to the arm will only remain. Further, by reason of this are adjustable, a complete and thorough tension mechanism is provided, which is capable rier by pressing or forcing the retaining-wire of imparting an unvarying tenslon on all the o3 away from the cam-web oL1 and toward the base O, to permit arm o to be swung outward and, further, that the friction between wheel Q and block P can be act-in a threefold capacity, thns dispensing with independent tenslon and straightening mechanism and greatly simplifying the construction ot' the machine. k marks a hollow shaft partly inclosed by the shaft e, but eX- tending in either direction beyond it, and having the disk Ksecured to it in front of the head E with a set-screw, 7c. This disk is provided with a number of arms, k2, projecting from its face,.to economize space, instead of from its periphery, as in the case of the head E, said arms k2 designed to carry spool-carriers is designed to prevent the spool revolving b reason of the spring of the wire coiled thereon. The base O is provided with a projection having an annular opening, o5, and set-screw o6, to enable the spool-carrier to be placed and disk K. Y l i It will be noticed from the drawings that carriers containing each a wire-bearing spool,

number of slots than the spider J, because of the pin g2, and'y lpartially inserted in the conretained on an arm, e2 or k2, of the head E or I the head E is capable of Vcarryin g twelve spoolare secured to IOO ing arm o', engageswiththe cam-web o4 on o, as clearly shown in Fig. 6. By this con- R, and that the disk K is adaptedto carry six spool-carriers, which also contain wire-bearing e spools.

and then inward curved direction to the rear end of shal't k, by which `'means a core for the strand-core may be passed-fronrthe core-spool g S to and into the hollow shaft @and thence to and into the tube ml of-the strand-core-laying head, to become incorporated into the strand-` core at the spider Y.` y

The spaces between the .spokes f2, rim f', and basefpermit wires from the spools on the head Eto be passed to thestrand-laying head, and the same provision is made with reference to the wires passingfrom the spools on the disk K to the.strand-eorelaying head.

' As shown in Fig.r3, the shaft e is provided in rear of the sleeve d' with a bevel-gear, e3, and the shaft lc has `,a vsimilar gear, It, at its rear end, both of which mesh with the bevel-` gear `t on the outer end of shaft T, held in bearings t', secured to the back `of `the arm d. l

As shown in Fig. l, the inner end `of shaft T `has a bevel gear, tengaging with the bevelvgear u, cast in one piece with or secured tothe Y `spur-gear U,toform adouble gear-wheel, which is free to turn on the main shaft B. l

Meshing with the spur-gearU of tlie'double gear-wheel is an idle wheel,V,adjustably held `by means of a journal-bolt, n, in the slotted sector e', secured "to the fraine A. 'l-he idle.` gear V engages in turn with the pinion ,zu V,on the shaft W, heldin bearings tothe franieA. Larger or smaller pinions may be placed onthe shaft W in lieu of the pinion fw. `The slotte? `in `the sector lv is concentric `with the periphl ery cf the main shaft B, so that when alarger 1 or smaller pinion is placedion the shaft VV,in

stead of the pinion shown, the idle-gear V may be adjusted in the slotted standard tocausedt to mesh with thespur-gear U and said pinion,

whereby an increased ordiminishedspeed gwill be transmitted from `shaft W to said double]` gear-wheel,.from which motion isconnmuni-l` ca tcdto the strand-head E `through shaft T,

its gears t t2, bevel-gears, and shaft e, and dto disk `K through said shaft T, its gears, the` bevelg-gieark, and shaft k.

Keyed to the shalt W is aspur-gear, w',

meshing with the idle-gear m, held by a journal-bolt, x', to the arm m2, formingpar-t of the .sleeve X, which is free to turn on main shaft w2 marks a'band-wheel keyed y indicates a shield to guide the rope-core to the shaft B,and y a pivoted lever, which rests s on one ofthe disks of the reel,andis provided `S marks Va eore-spoo1 suitably lheld on an arm, s,serewed into the sleeved', to which` also isv held theshield s', having retaining-l studs s2, said shield extending `in an outward with a weight, y2, whereby the rope-core will be .drawn from the reel under tension to pre Avent a `too `rapidl unwinding thereof.

`With the exception of the slotted sector fvf, with its gear V, and the fact that one idlegear instead; of two is interposed between gear w on shaft W and gear X on main shaft B, the foregoing-described drive and reel mechanism, including shaft T, `are identical with thosedesoribed in the application hereinbefore mentioned, to which reference is made for a whenceit may be passed to `a suitable reeling .device, to which motion maybe given through a belt engaging with .the pulley z2.

It will be seen from the foregoing that the main shaft receives motion through gear X', keyed thereto, while the groups of mechanism which are designed to form the strands and `strandcores receive motion from the double gear-wheel u U, loose on said main shaft B.

Assuming that the six lgroups of mechanism contain the required number of spools Rllled with wire, the core-spools S are filled with the `required cores, the reel Y contains the proper rope-core, the machine is properly threaded, and the wiresare drawn forward around the drawing-wheel Z and through the drawingrolls z', the operation of the parts to carry ont my improved method of laying individual wires TOO around cores to forni strand-cores, next laying individual wires Yaround the strand-coresto form strands, and lastly laying the strands around a .main or rope coreto form the rope in one continuous operation will `be as follows:

IIS

Upon ,giving `motion to the described drive ,v l

`mechanism the disks K are rotated on their axes, the individual wires are Adrawn fromgthe spoolsrlt in the spool-carriers on said disks, and,lpassi.n,g between the base M and sleeve on of the` strand-Acore-laying heads, arebent, l subjected to tensile strain, and laid around the core-wires passing fromthe core-spools S lto and in'to theV shafts k and tubes m to the spiders N to form the strand-cores, which pass to and through the tubes I to the spiders J of the strandlaying heads. During this operation of part-s the heads E revolve in an opposite direction to that of the disks K, the individual Wires are drawn from the spools R in the spool-carriers en said heads, and, passing between the sleeve h and base H ofthe strandlaying heads, are bent, subjected to tensile strain, and laid around the strand-cores to form strands, which, six in number, pass over the grooved rollers g', having bearings in the brackets g2, secured to the arms g, to and into the rope-laying head C, and are laid, in a reverse direction to the lay of the wires around the strand-cores, around the rope-core, passing from the reel Y to and into the hollow main shaft B to said rope-laying head C to forni the rope, said rope thence passing around the wheel Z and through the drawing-rolls e to a suitable reeling device.

It' desired, the disks K may be caused to revolve in the same direction as thatof the heads E by removing the shields s from the sleeves d to permit the bevel-gears k3 to be removed from the shafts k, then tightening the setscr'ews e, to cause the shafts e and lo to move together, and replacing the shields s.

It will be observed that the'strand-eore-laying heads rotate with the disks K, While the stral'ld-laying heads rotate with the heads E; further, that the groups ot' mechanism are carried around the axis ofthe main shaft B by means of the radiating arms d g.

When the heads E and disks K are iilled with spool-carriers containing wirebearing spools, the hoisting-rope shown in Fig. 9 will be manufactured upon putting the machinein motion.

A variety of ropes may be made by the machine herein disclosed, differing from that shown in Fig. 9 in the arrangement and number of wires, though involving in their manufacture all the steps of the process herein set forth.

No claim is herein set up for the machine shown and described for carrying out my iinproved process, as such machinei'ormsthesubject-matter of an application filed by me on the 12th day of August, 1882, numbered 69,225.

It will be noticed that lin the foregoing operation of parts to carry out my improved method or process the strand-cores, after being formed, are drawn Without being bent directly' to the strand-laying heads, where individual wires are laid around them to form the strands, andthat said strands are then drawn to the niain laying-head in au oblique direction and, Withoutbeing bent in any other manner, are laid around-the rope-core yto form the rope.

As is Well known in the art, the strand-cores, instead of being formed of a number of Wires laid around a core or center, may be made otl several wires laid together or around one another, in which event said core or center is dispensed with. This feature is one so well knownl to those skilled in the art of manufacturing wire rope as not to require further explanation in order to be fully understood.

Having thus described my invention, what I claim is- 4 1. The improvement in the art of manufacturing Wire rope, which consists in first laying individual wires around cores to form strand-cores, next laying individual wires around the strand-cores to form strands, and lastly laying the strands around a rope-core to form the rope, all in one continuous operation, substantially as set forth.

2. The improvement in the art of manufacturing wire rope, which consists in iirst laying individual Wires subjected to tension applied directly thereto around cores to form strand-cores, next laying individual wires subjected to tension applied directly thereto around the strand-cores to form strands, and lastly laying the strands around a main core to form the rope all in one continuous operation, substantially as set forth.

3. Theimprovement in the art of lnanufaeturing wire rope, which consists -in tirst laying individual wires around. cores to form strand eores, next laying individual wires around the strand-cores to form strands, and lastly laying the strands directly around a rope-core in substantially the same line ot' draft as thatin which the Wiresarelaid around the strand-cores to form the rope, substantially as set forth.

4. The improvement in the art of manufacturing Wirevrope, which consists .in first laying individual Wires subjected to tension applied directly thereto around eores to form strand-wires, next laying individual wires sub'- jected to tension applied directly thereto around the strand-cores to form strands, and lastly laying the strands directly around a rope-core in substantially the same line of draft as that in which the wires are laid around the strandcores to form the rope, all in one continuous operation, substantially as set forth.

In testimony whereof I ax my signature in presence of two witnesses.
