Application tiled November 28, 1881. (No mode1.)-

To all whom tvmay concern:

Be it known that I, MAHLoN M. ZELLERs, of Kent, in the county of Portage and State of Ohio, have invented certain new and useful Improvements in Machi nes-forMaking Rope, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it pertains to make and use it, reference being had to the accom panyin g'drawings, which form part of this specification.

My invention relates to machines for making ropes or cables of any desired length, without joint or splice, of that class in which the rope or cable is composed of strands each consisting of a core and layers of wire or threads wound around the same, cable itself-having a core. about which the strands arewound; and.y while the mechanism which I shall descrihe'is such as is particularly adapted for the manufacture of wire rope or cable,I wish it to be understood that it is equallyapplicable without material modification for the manufacture of bles from any pose.

My invention consists in the novel construction and combina-tions of devices which will be hereinafter particularly described and claimed.

In the drawings, Figure 1 is a view in elevation of my machine with some of the parts ropes, lines, or camaterial suitable for the puromitted to avoid confusion, the omitted parts the lowermain spider,

being understood to be identical with those which are shown. Fig. 2 is a horizontal section-on the line x x, Fig. l, showing a partial 'plan view of the driving gear-wheel and` the primary gear-wheel of the machine with which it meshes, also illustrating the construction of and showing partially the xed gear which meshes with the rotary main gear-wheelsof the spider. Fig. 3 is an enlarged view of aportion of the machine, partly insection.

Fig. 12illustratesa rope such as manufactured by my machine, said .rope consisting of a core andl six strands wound thereupon, each strand consisting of a central core with two courses of wires, thein ner course having six and the outer course twelve wires. Fig. v13 is a cross-section of the rope. Fig. `14 is a view of the devices for forming and guiding the finished rope. Fig. 15 is a vertical central section of the same at a right angle to Fig. 14. Fig. 16 is a fragmentary perspective view, illustratingcthe relativeposition of the arms of the two spiders which carry the upper spool-frames. Fig. 17 is a top view der carrying the guide-wheels for the uished strands. Fig. 18 is a detached perspective view of one of the dies. Fig. 19 is a side view of one of the spool-frames, showing the spoolbrake.

Referring -to Fig. 1 of the drawings, the letter A. indicates a. bevel-gear driving-wheel fixed upon a shaft, which may receive its rotary motion inzany convenient manner. This bevel-gear wheel meshes with a bevel-gear, B, which is rigidly keyed upon the vertical hollow shaft B', which is the main shaft of the machine, and carries the devices which produce the strands that 4.are broughtk together 1 and spiders which carry .the strandf forming and guiding devices,- and these spiders and the sets of the spin of strand-forming devices will vary-iu number according to the special character ofthe rope wound about a central core to form the finished rope.. Upon theshaft B are'xed a series of IOO to be made. In the present Iinstance I have shown the shaft B as provided with fourspiders, C, C', C2, and C, the lower spider, C, carrying the devices which place in position the cores y of the strands,Figs. 12 and13,and wind about said cores the first course of wires, y',and the two spiders C' and (32 carry the devices which apply the second courses ot' wires as shown at y2. The tirst course has six wires.and the second course twelve wires in the present instance, and the second is the outside course, though it will be understood that additional courses of wires may be applied,and the shaft B be provided with spiders carrying devices for that purpose. The spiders C', C2, and C3 are simpl y bands which surround the shaft and have radially-projectin g arms c' c2 c, respectively, which carry at their ends the devices `which the spiders are intended tofsupport. The lowermost spider, C, is composed partly by the bevel-wheel B, the spider-arms c having their inner ends secured in sockets or seats formed for them in the upper face of said wheel. The mechanism for forming the strands comprise, among other devices, revolving sets of spoolframes,in which are mounted the spools which deliver the wires for the cores and surrounding courses. These mechanisms will be hereinafter particularlydescribed. The uppermost spider, C, carries at the ends of its arms c3 simply the outer friction grooved guide-wheels R, over which the completed strands pass to guide S above. The lowermost spider, C, has six arms, c, as indicated in Fig. 2, and, as be fore stated, carries allthe devices for placing the strand-cores and winding thereon the first courses of wires; ybut for carrying the devicesl y for ka ppl yin g the secondy courses'of wires I havek 40 i f yarms of one projecting opposite the spaces be-r fonnd'it convenient yto yusetwo separate threef armed spiders-yonefabove the other-@andthe tween the armsof the other, yas shown in Fig.

' 16. yThereason for this'arrangementis'thatl the set of spoo'hframes for applying the outer ycourseof wires to aistrand carries ytwice as many spools as does the` corresponding Set of yspool-frames below for applying the first course lof wires abouty the core, and such upper `circle i y upper set,

55; c hollow shaft: of the upper set `of spool-frames, and thus avoidthe necessity of its'beiug'bent of spoolframes has therefore twice the diam-rr eter of the lower. upper rand lower sets of spools shall be so arf n rangedthat the axis of each lower 'set4 shall;

- It isdesirahle that, these heinline with the axis of the ycorresponding may pass from the lower'guidedirectly to the over guides. If the upper sets' were all carried by a single spider, krsnch spider would necessarily have very long arms,in order that its sets of spool-frames might be in a circle where they would have room to revolve clear of each other, and then the lower spider would have to be provided with arms of the same length as the upper spider, in order to bring its sets of spool-frames in a circle having the same diameter as that of the upper sets. By diin order that they unfinished strandk riding the upper sets of spool-frames into two divisions, however, it will be seen that I avoid using spiders of such large size, the sets ot' spool-frames of one division having ample space to revolve in a different plane from those of the other division, while their centers are in vertical line with the centers of the respect. ively corresponding set of lower spoolframes. The shaft B has its upper and lower journals arranged in suitable bearings, and when it revolves of course .revolves .the spiders and the mechanism they support.

D is a fixed horizontal annular gear-wheel, surrounding concentrically the shaft B and rigidly supported by standards d, secured to the bed-plate or foundation of the machine. This fixed wheel meshes with rotary gearwheels E, ixed upon 'the lower ends of vertical shafts E', which have their lower journals supported in bearings formed in the ends of the arms c of the lower spider, C, and their upper ends loosely connected with the lower ends of vertical hollow shafts E2, which have their lower bearings in the ends of the arms of the spiders C and C2, respectively, and their upper bearings in the ends of brackets M, fixed upon said arms. The lower vertical f shafts, E', are connected with the upper shafts, Eby reversing-gearing, (shown at K, K', K2, K3, andK, and which will be more fully hereinafter explaiued,) so that when the shafts E are rotated in one direction, as indicated by the arrows marked thereon, motion in a re verse direction will be transmitted, through the gearing referred to, to the shafts E, as also indicated by arrows. VThe shafts E' carry spiders Ghaving at the extremities of their arms g bearingsg'; fori thelower journals of, ,les y,

the rotary spool-frames F", in which are mountk ed the spools f, and said shafts also carry, at'

' a suitable distance above the spiders, rings Gf, t c yupon which are formed the bearings g2 for the upper journals ofthe said spool-frames'. The

spool-frames F7y are 'provided with pinions F2 and each,through its said pinion and gearing (shown .at E F F2 F? Fiiand shaft F4, receives a rotary motionaboutitsaxis, in addition to being carriedaround by the' spider G and ring G when they shaft E' rotates.` The gearing y for transmitting motion k,tothe rspool-frames y will bepresently described more particularly.

The upperjournalsofthe spool-frames F7, are t tubularfasy shown in Fig. y3**a'nd through; these` journals the wires pass from the spools f,.`and thence directly throughy passages in a t f ,c

guide, H2,

H', which forms the top portion `of yshaft shown in Fig. 1, the wires from the spoolframes F7 pass under'guidepulleysf, instead of directly to the guide H above, said pulleys being mounted at the ends of arms projecting from the shaft E' on that side which is longer than the corresponding shaft E at the left, this increased length being rendered necessary by the fact that the devices with which the yasshown at the left rin Fig. 1, and 'n' i up through a die, H, arrangedwithin a franige,

On the right-hand sideof the machine, as."

i shaft at the right is connected at its top are der Gr` has seven arms,

atenas carried by, the` arms of spider ,C2-'which is higher-on shaft B thanv is the spider C', for the reason already explained; the guide H2 at the top ot" the right-hand shaft beingl atsuch a distance from the tubular journals ofthe spool-frames below, the wiresissuing from said journals would rub against the inner edges of the upper ends of said. journals if led directlyto the guide H2, aand `cause a considerable resistance to the turning ofthe spoolframes and a seriously detrimental wear ot' the wires and journals; hence the necessity of. the guide-pulleysf", which guide the wires centrally from the tubular journals. The spias shown in Fig. 4, and carries seven spool-frames, the spool f ot' one of which supplies the core wire for the strand, and the spools ol1 the other six supply the wires for the first course. The guide H2 has one of its passages, as shown in Figs. 11 and 11, formed to guide the core-wire, as shown at y, straight up through the centerot t'h die H,

ywhile the passages for the other wires terminate at their upper ends in a circle about the passage for the core-wire, so that as the guide revolves the six Wires from the outer passages will be wound upon the core-wire spirally, it being understood, and as will be hereinafter explained, that the wires are all drawn along together at a propel' speed. From the die Il, that part of the strand which is formed by the devices carried by shaft. E', and which consists of the core-wire and the first course of six wires wound thereon, passes straight upward through the tnbularshaft E2, and through the die Q carried at the top of said shaft,and as it passes through the die has applied to it the outer course ot'twelve wires, which are drawn from the spools carried4 by the spoolfra mes f', which are supported by a'spider, L', carried by the hollow shaft EZ, and are revolved in a direction the reverse of the movement of the lower set of spool-frames, so that the outer course of wires swound oppositely upon the inner course. A more detailed description of the devices for applying the outer course of wires will presently be given. The finished strands from all the dies Q of the ma! chine pass over the respective grooved antifriction guide-wheels R, which are mounted at the extremities of the arms ot' the upper spider, C, which is fixed upon the main shaft B. The dies H and Q simply serve to hold the strand steadily, and their rotary motion results only from its being convenient to mount them upon the rotary shafts instead of constructing stationary, supports forv them. From the guide-wheels R the finished strandssix in number in the present instanceare converged toward a thick circular plate, S', which is fixed upon and vquite near the upper end of the main shaft B', and forms an extended npperjonrnal forv said shaft, having its bearing S2 formed in a tixedheavy top plate` S, which is supported by bea-ms S4, suitably arranged in the building in which' the machine is erected.

passage,

This plate 'S' has suitable openings, through which the strands pass to aguide, S, which is xed upon the top of the shaft B', and has six upwardly-com'erging passages, s, terminating at their upper ends in a circle about an axial s', the axis of which is in line with that ofthe bor or central passage of the shaft B'. The guide `S has a hollow central shank, s2, which projects from its lower face, and this shank tits into the upper end ofshaft BA', whereitis secured by suitable screws passed through the wall of the shaft and bindingupon the shank. The strands Y pass upwardly from the guide S through a stationarydie, Q', which is supported by standards q q', secured to the top plate, S3, and as they pass through said die are, by the rotation ,of the shaft and guide S, laid splrally, around a core-strand, Y', which is drawn upwardly through the tubular main shaft B thus l'orming the complete rope Z. The completed rope, consisting of the core-strand and the six outer lstrands coiled thereon, passes from the die Q to a suitable take-up reel, (not `shown in the drawings,) the speed of which is to be regulated in the ordinary manner employed for regulating the take-up reels of ropemaking machines. 'lhe take-up reel may be located at any convenient point, and the rope pass to it over suitable guides.

I have not deemed it necessary to show in the drawings a reel for delivering the corestrand which passes upward through the tubular shaftB, as it will be readily understood that such a reel may be arranged as required or convenient, and the strand guided to the open lower end of the shalt in the ordinary manner.

When by meansot'the driving-wheel A, which meshes with wheel B, rotary motion is communicated to shalt B', the rotary gear-wheels E are caused to traverse the periphery of the lixed gear-wheel Dand receive motion therefrom, this motion being in turn communicated through all the shafts E( and E2 to all the strand-making mechanisms, and the take-up reel winds up the completed rope.

The strand which fortnsthe core of the completed rope may be similar to theouterstrands, or may be of jute or any other desired material. This core-strand is of course manufactured prior to the commencementof the making of the rope by the machine, asdescribed.

Having now given a. generaldescription of the construction and operation oi' my machine as a whole, I will describe `with particularity and in detail the mechanism for making a single strand ofthe rope, it being understood, as ,alreadystateth that the several complete sets ot' strand-makin g mechanisms are identical in construction and operation.

As already stated, the vertical shaft E haa, its lower bearing in thev end ofone of the arms 4c ofthe lowermost spider, C, and has xed upon its lower end, which projects below said bearing, a gear-wheel, E,which meshes 'with the tixed gearD.- On the upper side of the end and central passage of the guide S,

y l i of the'arm e is rigidly `fixed au annular gear,

having seven arms, carrying the spool-frames' F, each of said spool-frames having rotary motion about its,axis as well as a revolving motion with the shaft E. The fixed .gear F meshes with a rotary gear-wheel, F5, which is keyed upon the lower end of a short shaft, F,

which has itslower bearing, f, carried by the spider G, and its upper bearing in a bracket, f,which is fixed upon the shaft E'. Upon the upper end of shaft F* is fixed a gear-wheel, F3, which meshes with an intermediate pinion, F, mounted upon the bracket, and this 4pinion in turn meshes with the spur-gearf6 of a double gear-wheel, F', which is loosely mounted upon the shaft E' above the bracket f, and has a bevel-gear face, f which meshes with the pinions F6, with which the spool-frames F7 are provided. It will now be readily understood that as the shaft E revolves the spider G and bracket f in the direction indicated by the arrows the gear-'wheel F5 will be caused to traverse the toothed periphery of the' fixed gear F and receive motion therefrom in the direction indicated by the arrow on shaft F,

and that motion in the same direction is caused in gear F3, and through pinion F to the loose double gear F', the bevel-face f "of which turns the pinions Fs and causes the spool-frames F" all to rotate about their axes in' the direction indicated by the arrows marked thereon. The purpose of this rotation of the spool-frames about their axes will be presently explained.

Each of the spools f has one of its heads of greater diameter than the other, as shown at f", and this extended head has a broad periphery and enters a recess in the side of the spool-frame when the spooi is in place on its spindle. Upon the edge of the spool-frame is secured one end of a finger-spring, f9,thc outer end of which bears upon the periphery of the spool-head, as shown in Fig. 19. Loosely through an intermediate portion of the spring f 9 passes a thumb-screw, f1", which is tapped into the spoolframe,its head bearingupon the outer surface of the spring. By adjusting the screws the spring may be caused to bear with greater or less tension upon the head of the spool, and the `spool may be thus prevented ,from givingoff slack wire: The gearing for imparting the motionto the spool-frames about their axesis so timed or proportioned that each spool-frame F1 shall make' one complete rotation upon its own axis for every revolution it makes about the axis of the shaft E', this being for the reason that otherwise the wire drawn from the spools would be twisted individually, and not only thereby weakened, but laid in the rope-strand under a strain that would cause the kinking of the strand and also of the finished rope. v

As before explained, the shaft E' carries the frame H', which springs from the guide E, which is fixed to the upper end of the shaft proper, and this guide has its passages properly arranged to guide one of the seven wires straight up through the die H and the'others to be coiled about it. The die H is composed of two bars, h h', hinged together at one end, and the bar h' having at the otherend a tongue, h, to enter a slot in the bar h, the tongue h and bar h being provided with pin-holes, in which a pin h3, may be inserted to lock the two bars toget er. Each bar has formed in its inner fa'ce a semicircnlar cavity, and when the two bars are closed together these two cavities 4form the 'circular passage of the die through which the strand passes, and is thus kept to uniform size. The bars are supported by standards h h', one of which preferably forms thehinge-pin. The standards are screw-threade'd on their upper portions, and adjustable nuts h5 h5 are used to regulate the height of the die from the guide as desired.

Havin g nowdescribed the mechanism for placing the core and laying the first course of wires ofthe strand, I will proceed to describe the devices for laying the second course, which is to be wound in an opposite direction to the first course. To accomplish this reverse winding the tubular shaft Ez is given rotation in an opposite direction to the rotation of shaftE', and this opposite rotation is accomplished by the gearing shown at K, K', K2, K3, and K, as follows:

K indicates a gear which is rigidly attached to the top plate, H3, of the frame H', which is carried by shaft E', and this gear rotates with said shaft in the direction indicated by the arrows marked thereon. The shaft E2 projects below its bearing in the end of the spider-arm which carries it, and its lower end passes through the central aperture of wheel K and top plate, H3, thus forming a pintle about which the wheel K revolves.

Theintermediate or reversing gear-wheel, K', is mounted on astud projecting from a bracket of the spider-arm c', and meshes with wheel K, and also with the gear-wheel K2, which is keyed to the lower projecting cud of a vertical shaft which plays through a bearing formed in the arm c', and has keyed to it, above said bearin g, the gear-wheel K3, which meshes with the gearwheel K, which is keyed upon the shaft E. The gear K, through the intermediate gear, K', imparts motion to the gearwheels K2 and K3 in the direction of the arrows marked on said wheels, and the wheel K3 turns the wheel K4 and shaft E, upon which it is fixed, in 'the direction of the arrow on said shaftthat is, in a direction the reverse of the rotation of shaft E.

The shaft E', as already explained, carries the spools which supply the wires for the outer course of the strand, and these spools are mounted in spool -frames f', identical in construction and operation with the spool-frames F" already described. The mechanism, however, for imparting motion to the spool-frames f is different from that described for moving the lower spool-frames.

IIO

A fixed wheel, L,is firmly secured `to the end of' an amm-M, projecting from army c" and said wheel. A crown-spider, L', is fixed upon shaft E2, and lis provided with downwardly and outwardly projecting armsl, having bearlution about the axis of shaft E2.

ings l' and l2, in which are mounted the journals of the spool-frames f. Upon the top plate of the crown-spider L' isV mounted a.

double annular gear, L2, surrounding the shaft .E2 and having its bearing on the margin of said top plate.` This annular gear has any outer bevel-gear face which meshes with the bevel-pinionsj`2 of' the spool-framesf', and an' interior spur-gear which meshes with apinion, L4, keyed to the upper end of a short vertical shaft which is mounted in a bearing formed,

in the spider L', andhas fixed to its lower end a pinion, L3. When the shaft E2 rotates in the direction indicated by the'arrow marked thereon the pinion L3 is caused to traverse the toothed periphery ofthe fixed gear L4 and receive therefrom motion, as indicated by the arrow, and the pinion L4, moving in the same direction, drives thev annular gear L2 around on the top plate of spider L', so that the outer bevel-face of this gear communicates a rotary motion to the spool-frames through their pinionsf2, this motion being in the direction indicated by the arrow on the pinion f2 in Fig. 3.

The gearing which communicates motion to the annular gear L2 is so arranged as to canse said gear to move more' rapidly than'the spider L', so that said gear makes a complete revolution with the spider andan additional movement besides while the spider is making one complete revolution, the additional movement being sniicient to communicate toeach spool-frame f' a complete rotation about its axis in the same time that it performs a revo- The rotation of' the spool-frames on their axes is to prevent the wires from being individually twisted, as before explained with reference to the lower spool-frames. There are twelve ofthe spoolframes f', and the wires are led from the spools through the tubular upper journals of said frames the same as in the frames F", passing thence under grooved anti-friction wheels O, carried by the arms of alsmall spider, 0', fixed uponshaft E2.

Upon the hubo of the spider O rests the first section of a tension device, P, which is a cone composed of sections which are alternately loose and fixed upon the'shaft E2, the

sections p being loose and those marked p' being fixed. Projecting from these sections, respectively, are lugs or pinsarranged inlines from base to top of the cone, there being a line of pins for each wire, and the wire is passed alternately on opposite sides ofthe pins in a line, and from the top pins lall the wires pass through converging passages in the extended top section, which is fixed upon thevtop of shaft E2. From the passages of' this top section the wires pass through the converging -*passages ofafgiuideplate, H4,'fixed upon the top section andhaving a central larger pas.- sage which has its axis in linewith that of the bore of the tubular shaftE2. f

It has already been explained that the partly finished strandpasses upwardtlirough the hollow shaft E2.- It passes out through the central passages of the top cone-section and the guide-plate H4, and thence through the center ,ofa die, Q, in all respects similar to the die H,

heretofore described, 4but having a larger passage to accommodate Ythe increased size ofthe strand. As the strand, in its unfinished state, vpasses through the die Q the revolution of the shaft E2 causes the converging twelve wires Vfrom the upper spools, to be wound spirally about it in opposite direction to the first course of six wires, and 4the completed sii: strands which are to be applied to a main core to complete theropeall pass from the dies Q over `the wheels R, and are converged through the main upper guide and applied to the main core in the main die Q', as has been hereinbefore fully described.

It is obvious that I need not limit my invention to the use of any definite number of spoolframes ,in a set, nor to any definite number of the series of spool-frames, as this will be determined by the number of strands that a iinished ropeis tov have, or to the number' of courses of strands that 1a ropemay have. For instance, if a rope is desired to have a central core and two courses of strands, the machine would require a corresponding number and series of strand-making devices and their actuating mechanism to' accomplish the Work.

It will beA observed that by lthe use of my machine I can make a continuous unbroken r'pe of any length whatever, because when the IOO wire'npon any spool is exhausted the mere splicing of that single wire will not affect the strength of its strand or of the rope, and notwo Wires need break jonts at the same place' in a rope.

In practice, 'when a spool of wire has been exhausted 1 have been accustomed to braze the end of' the wire to afresh spool, and thus have in effect single unbroken wires in every strand.

Having fully described and explained the construction and operation of my invention, what Iclaim is` 1. The combinatiomwith the fixed or stationary gear D, of the central rotary shaft, B', the
