IMPROVEMENT IN MACHINERY FR MAKING ROPE.`

Specification forming part of Letters Patent No. 10,866, dated May 2, i854.

To all whom t may concern:

Be it known that I, WILLIAM ROBINSON, Jr., of VarSaW, in the county of Vyoming and State of New York, have invented a new and useful Improvement in Machinery for Making Rope; and I do hereby declare that the following is a full, clear, and eXactdescri ption of the construction and operation of the same, reference being had to the annexed drawings, forming part of this specification, in which- Figure l is aside elevation of the machine. Fig. 2 is a top view of the same. Fig. 3 is a vertical section on line a x, Figs. l and 2, looking toward the iiiers. Fig. 4 isalougitudinal section of laying-piece. Fig. 5 is a side and face View of meeting-piece.

Similar charactersof reference denote the same parts. l

My invention consists inthe employment, inthe manner hereinafter tobe described, of a ring with cogs on both inner and outer edges, said ring being revolved by pinions meshing into the exterior cogs for the purpose of regulating the relativetwist of the separate strands and the entire rope by'diminishing to a greater or less extent, as will be described, the number of revolutions of the fliers upon their axes while performing a single revolution about the main axis; also, in an arrangement of clamps, hereinafter to be described, forreceiv-A ing the finished rope, firmly holding it during the laying operation, and finali y conveying it from the machine.

In the drawings, a is the main shaft, to which the power is applied, securely fastened to which are the tri-branched bearings b, each pair supporting one of the iiiers A, these fliers being long boxes containing the spools B and rollers O, the number of the former being regulated by the size of rope required On the inner extremities ofthe iiiersA are the pinions c, which mesh into the inner circle of cogs on the ring d, the outer cogs of said ring meshing into the pinions e and being held bel tween the Wheelsf' and g. The shaft a has on its outer extremity the cog-wheels 7L and h',

' meshing into the wheels t and t" on the shafts D. Inside of the ring (Z is the beveled cogwheel Z, in which mesh the beveled pinions Z', which carry the grooved rollers rm, ontheir largest faces. Pressing against said rollers m are the rollers n, held by the arms o of the ring p, the spring q, which acts on the ring p, serving to keep the rollers m and n closelyT in contact.' At its inner support E the shaft a is enlarged, so as to contain channels for the passage of the twisted yarn to the layingpiece o', which fits into the socket s, as shown in Fig. 4, the bore being regulated by the size of rope. The socket s screws upon the headt of the shaft a, upon which, between the outlets for the twisted yarn, is a point to, around which the lay of the rope is made.

Upon the inner end of the shaft ct is the cog-wheel o, meshing into the wheel w on the shaft a', the screw 1j ot' which revolves the wheels, Vturning the shaft a', and with it the system of clamps or pinchers. These clamps or pinchers b have in their extremities the wheels c', which by running over the cams d close the jaws of the clamps or pinchers,which at all times have atendency to open by reason of the springs c. The shaft can beshif'ted from the bearings f to the bearings g', so as to cause the screw y to mesh into the cogs of the wheel z and change theyelocity of the clamps or pinchers ZJ.

The operation of my improved machine is as follows: rlhe requisite number of spools B lilled with yarn are inserted in each iiier A, `the number depending upon the size of rope to be made. The yarn from every spool in each iiier is passed around the rollers C of the iiiers-and carried through the openings s of the pinions O and betwen the grooves of the rollers m and n to the channels t in the enlarged portion of the shaft a, whence the strands issue by the outlets o and passing through the laying-piece r are carried toget-her over the pulley c to the jaws of one of the clamps or pinchers b. The yarn being thus arranged, the shaft a is rotated by power suitably applied, carrying with it the fliers A,

which as they revolve have each an independent rotation about their own axes in the opposite direction from their 4revolution about their main axis. This independent rotation is caused by the meshing of the cog-wheels c in the inner cogs of the ring d and gives the twist to the strands, while the revolution of the iiers about the shaft a causes the laying of the rope. The rotation of the shaft d revolves the shaft in the opposite direction through the wheels fo and w and by the movement of its screw y in the cogs of the wheel .e rotates the shaft a in the direction of the arrow, causing a movement of the clamps b in the same direction, with the effect of drawing out the yarn secured by them in the direction indicated by the red line in Fig. 1.

During themovement ofthe fliers and other parts of the machine, as above described, one of the wheels h or 71, revolves the shafts D through the wheelsz' or t', causing, by reason of the pinions e, the revolution ot' the ring d inthe direction of arrow 2 with a velocitydepending upon the following causes. The wheels h and h are so attached to the shaft a that but one at a time is revolved by it, the other at that time turning loosely upon it. Consequently if the wheel h be secured to the shaft d the wheels 't' will govern the revolution of the shafts D and the velocity of the ring (l, while on the other hand if the wheel 7L drives the shafts D the velocity of the ring d will be greatly increased. Any of the usual devices for gearing and ungearing may be employed for fastening the wheels z and h.

The effect of the above-described motion of the ring d upon the formation of the rope will be readily understood from an examination of the functions performed by the several parts. The revolution of the fiiers A about the shaft a performs the laying of the rope, while the rotation of the same about their axes and in the opposite direction gives the requisite twist to the several strands, the amount of which twist will depend on the number of rotations on their own axes to a single revolution about the main axis d, which number of revolutions of the fliers will of course depend on the distance passed overon the inner edge of the ring d by the pinions c of the iliers A. Therefore the greater the velocity with which the ring d revolves the smaller will be the number of cogs which the pinions c can mesh into during a single revolution of the fliers about the shaft a, and the fewer will be the revolutions of the fliers A about their own axes in the same space of time. regulate the twist given to the strands composing the rope it will merely be necessary to give the ring cl the proper velocity byy a suitable arrangement of the driving-gearing, for instead of employing Wheels of but' twosizes, as shown in the drawings, there may be a, series of wheels of various sizes, any desired set of which maybe thrown intogear to` properly graduate the volocity of the ring to the nature of the rope to be made.

The several strands en ter the enlarged shaft Consequently it will be seen that toY d, as shown in Fig. 1, and pass through the channels t', (seen in Fig. 5,) and issue by the apertures b around the point f@which enters the cavity in the laying-piece, as shown by Figs. 4 and 5. This laying-piece r has abore adapted to the size of rope required, through which the rope passes to the clamp b', as shown inFig. l, the lay being made around the projection u by the revolution of the fliers, as above described, the clamps b keeping the finished portion perfectly tight during the operation, and finally carrying the rope clear of the machine. l3nt four clamps b are shown in the drawings, though in practice there may be more employed, the objectv being. to seize and hold the rope as it passes over the pulley c" before the preceding clamp has released its hold. The cams CZ close the jaws of the clamps as the clamps advance to the rope, and the springs c open the1n,'when the forni of the cam d causes a relaxation of pressure. The velocity of this portion of the machine must be adjusted to the movements of the other portions, for which purpose a number of wheelsz z', dto., are provided, with bearingsf, g', dto., into which the shaft maybe shifted, so that the required velocity may always be produced.

The principal advantages of this machine consist in the facility which it affords for regulating the twist of the strands, a feature of the utmost importance in machines of this character, as the too great twisting of the strands prevents the effectual lay of the rope, and the lack of twistis equally detrimental to its quality, defects well understood by ropemaliers, and the importance of the proper regulation of which will require no argument to render apparent.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

l. The employment of the cogged ring d, arranged and operating as described,for. giving the fliers their independent rotation for twisting the strands and. by its own revolution regulating the amplitude of `that twist, as andl for the purposes set forth.

2. The employment of the rotary clamps b',

in combination with the 'cams d and springs e', for grasping, conveying, and releasing. the rope, as herein fully set forth.

In testimony whereof I have hereunto signed my name before two subscribing witnesses.
