IMPROVEMENT IN STRAND-TWISTING MACHINES FOR ROPE-WALKS.

Specification forming part of Letters Patent No. 122,653, dated January 9, 1872.

SPECIFICATION.

N ctw@ and Object of the Invention.

My .invention consists of a strand-twisting machine provided with a number of simultaneously-operating fliers arranged at one end of a rope-walk, and combined with ahauling-machine, as fully described hereafter, so

that any desired number of strands, of any `thickness and degree of twist, and of exactly the same length, can be simultaneously formed. Description of the Accompanying Drawing.

General Description.

The fixed portion ofthe machine consists oi' the end and center frames A Al and A2 connected together by horizontal bars B, B1, B2, B3, and B4, and in suitable bearings c a a, formed in the brackets which project outward from the front of this ixed frame, turns the main driving-shaft D, furnished at one end with a chain-Wheel or pulley, b, and ily-wheel, bf; and furnished, also, with a clutch, not shown in the drawing, by which the shaft may be thrown out of gear With the driving-pulley. On the driving-shaft, at regular distances apart, is a number of bevel-wheels, c, from each of which motion is communicated, through the gearing hereinafter described, to one of a number of iiiers, F, there being, in the present instance, six ofthe latter, but this number may be increased or diminished according to the number of strands which it is desired to form and twist simultaneously by the machine. Each iiier consists of two circular plates or disks, d'and' d', connected together by rods e e, and from these disks extend the short tubular spindles f and f ofthe flier,

each of which turns in a suitable bearing, g, of the fixed frame. On the front portion j' of each flier-spindle is a pinion, h, which gears into a large cog-Wheel, It', on a short spindle, Gr, turning in the flXed frame, and on the said spindle there is also a small bevel-Wheel, c', gearing into one of the larger bevel-wheels c of the driving-shaft. Through the medium of this gearing all of the iiiers are turned simulv taneously and at a high and uniform rate of speed by the lsingle `driving-shaft D. (See Figs. 2 and 3.) Within each flier, at points directly opposite the open flaring ends of the tubular spindles f and j", are lixed two sheaves, z fi', which direct the sliver or strand onto and oft' of two capstans, j j, which are hung to and arranged to turn within the iiier. Each of these capstans has at one end, Within the flier, a small cog-Wheel, 7c, which gears into a smaller wheel, kf, at the inner end of a tubular spindle, l, the latter extending' through and turning inl] the tubular spindle f' of the iiier, and being provided, at its outer end, with a cogwheel, m, which gears into a wheel, m', on a short spindle H, capable of vertical adjustment in the tiXed frame toward or from the flierspindle, and furnished with another cog-wheel, n, which gears into andreceives its motion from a cog-Wheel, p, on the said dier-spindle. By means of this gearing the inner tubular spindle l is turned in the same direction but at a somewhat greater speed than the Hier, this inotion of the said spindle being transmitted to the capstans j j, Which are consequently turned in the opposite direction at the same time that they are carried round with the iiier, the object of which Will be hereafter described. (See arrows in Fig. 4.) A plate, K, perforated with a number of f holes through which the threads which are to form the strands are drawn, is secured to rods p p of the iiXed frame, at a point directly opposite the rear open end of the tubular spindle ot' each flier, and the said plate is made adjustable upon its supportingrods, so that it may be brought close up to or be moved outward from a plate, L, which intervenes between the perforated plate and the end ofthe dier-spindle, and through a central opening in which all of the threads are caused to pass before entering the said tubular ilierspindle. (See Fig. 3.) Theslivercomposed of y the threads drawn through the plates K and L, and which is to be twisted, in order to form a strand, is passed through the inner tubular spindle l, as shown in Fie'. 3; thence over the sheave i, and several times around the grooved capstans j, and thence over the sheave fi', by which it is guided into the front portion j' of the tubular flier-spindle, from which it finally passes. The sliver is twisted within the tubular spindle l, owing to the motion of the flier, and it is at the same time drawn through the latter at a slow but uniform rate of speed by the independent movement of the capstans jj, the strand thus produced, of whatever length, being of the most even character throughout.

It will be evident that the degree and character of the twist given to the strand will depend upon the rapidity with which it is drawn through the flier by the capstans j j, and this can be regulated with the utmost nicety by imparting any required degree of speed to the said ca-pstans by means of the change-wheels on the adjustable shaft H. The latter is so arranged upon the frame that it can be disconnected and wheels of any diameter substituted for the wheels m and a, shown in the drawing, the shaft being adjustable in the frame to\ Yard or from the Hier-spindle, so that it may be properly set to suit the different diameters of wheels employed.

By means of this arrangement, which is a most important feature of the machine, strands of different diameters and of diferent degrees of twist, suitable for various kinds of rope, can be formed.

Another important feature of the machine is the arrangement upon the same of a number of simultaneously-operating iiiers, as this enables any desired number of strands, precisely alike in every respect and of the same length, to be simultaneously produced, the rope formed from such strands being consequently of a much .more perfect and even character than those made inthe usual manner from separately-formed strands. j

In operating the machine it is arranged at one end of a rope-walk, and the several strands as they emerge from the tubular spindles of vthe fliers are drawn away and carried down the walk by what is commonly known as ahaulingmachine, which receives its motion from an endless band, rope, or chain, passing round the pulley b of the forming-machine and running further twisting or untwisting of the said strands.

When strands of the whole length of the walk have been thus formed the motion of the forming and haulin gmachineis stopped and the strands are then disconnected and thrown over on that side of the walk called the layingground, where they are laid together, the several strands formed being of an exact length, and ready to be formed into rope.

In the ordinary method of forming the twist is given to the strands by a hauling-machine instead of by a flier, rotating at the saine speed as and operating in conjunction with the hauling-machine. The objection to this plan of twisting by means ofthe hauler is that when thc strand is drawn out to a considerable length, it is apt to become stretched and twisted very unevenly; whereas in my machine the Hier, which is the twisting device, is always at a uniform distance from the point at which the threads are fed, and the strand is drawn along at a uniform rate of speed bythe hauler, the consequence being, as before described, that the strands are perfectly uniform throughout.

Claims.

l. The combination, with the flier of a strandtwisting machine and with the capstansjj of the same, of the adjustable sha-ft H and its change-wheels, all substantially as and for the purpose specified.

2. The combination, in a strand-twistingmachine, of two or more iiicrs, F, a hauling-niachine, and a single driving-shaft, D, operating both iliers and the hauling-machine, whereby all the fliers are rotated and all the strands drawn out at the same speed, so as to produce a series of strands uniform throughout.

3. The combina-tion, substantially as herein described, of a flier with a hauling-machine.

4. A strand-twisting machine, arranged at one end of a rope-walk, provided with a number of simultaneously-operatin g lliers, F, and operatin in con j uction with a hauling-machine, and with the mechanism described, or its equivalent, for operating the hauling-machine in unison with the fliers, substantially as herein set forth.

In testimony whereof I have si gnedmy name to this specification in the presence of two subscribing witnesses.
