. Be it known that I, WILLIAM LANCASTER, a subject of the Queen of Great Britain, re siding at Accrington, in the county of Lari caster and Kingdom of England, have invented certain new and useful Improvements in Machinery for Spinning and Forming the Same into Oops or Bobbins, (for parts of which I have a patent in Great Britain, No. 4,263, hearing .date September 7, 1882; apatent in France, No. 154,133,

hearing date March 6, 1883, and a patent in No. 59,324, bearing date October 19, 1882,) of which the following is a specification.

- My invention relates to machinery for spinning and, doubling yarn continuously; and it consists in certain novel combinations and Y modifications in the constructionof the .Wellknown ring-spinning machine, and more especially in the means devised for spinning and'twisting all kinds of fibers on the bare spindles of such machines; together with the various mechanical movements anddetails of construction incident thereto, as will be hereinafter fully set forth.

In the accompanying drawings, Figure 1 is an elevation, partly in section, showing a-portion of the feed-rollers, guide-plates, ring-rail, spindles, and driving-gear of [a spinning-machine embodying my improvements, together 7 with the mechanism employed for controlling and varying the traverse of the-ring-rail dur-' ing the various stages of the formation of the cop.

In Fig. 1 of the drawings are shown the principal parts of one side of a ring-spinning machine, constructed according to my invention, in which A is one of the driving-gears,

that is suitably connected to the main shaft A, and thence to the source of power, by the intermediate train of gearing, consisting, as

shown in Fig. 6, of the wheel A pinion a",

wheels A A, pinion d wheel A, and a is a worm-gear mounted upon a shaft,, A, which extends downward and is stepped into a suitable support, A. Upon shaft Ais mounted a cam, B, above which is located a sliding plate, 0, which, being sup-' ported upon suitable guides or brackets, U, attached to the frame of the machine and provided at its under side witha stop, b, in the path of'the cam B, will be driven in one direction by the rotation of said cam and re tracted by the weight ofparts connected thereto. This sliding .plate is reciprocated hori zontally by the action of the cam against its stop, and carries a movable hearing or fork, d, which is displaced as the formation of the cop progresses, the fork d being gradually moved along the plate 0 toward the shaft A by mechanism (to be-described) actuated at each reciprocation of the plate 0.

, ,At one end of the plate 0 isa fixed bearing, d, in which is mounted the outer end of a screw-shaft, G which is providedat its opposite extremity with a ratchet-wheel, d, and a gravity-pawl, 6, carried by a pivoted arm, 6,

the plate 0.

The movable bearing or fork d is mounted upon and adapted to slide freely along the plate 0, which supports'it, and it also affords additional support to the screw-shaft O, by the step-by-step rotation of which it is gradually moved toward the shaft A.

A wedge or inclined surface, 0 'is fixed to the frame in the path of the arm 0', and at each backward'movement of the plate the said arm is forcibly raised, thereby rotatingthe screwhaft to the extent of one tooth of and belt-wheel D A worm-wheel, a, is carried upon the shaft of 6 the ratchet and moving the bearing or fork d rearward on the plate 0.

From the fork (1 extends a chain, d, which passes over and is secured to adrum, G, preferably located in the same plane as and near the inner end of the plate 0, which, besides being rocked upon its axis as the plate 0 moves backward and forward, is gradually rotated by the retrograde movement of the part to which its connecting chain is secured. The chain or band (1 is connected to the fork d by means of a hook or other suitable device which may readily be disengaged or detached therefrom, and this chain extends to and is secured upon the drum G, which is mounted upon axis F near the inner end of the plate 0.

Upon the periphery of the drum G and directly in the line 01' the chain'cl is placed an adjustable stop or projection, H, over which the said chain rides at each oscillation of the drum until said drum is rotated a sufficient distance to carry the projection H out of the way of the chain.

A second chain or band, (1, is also secured upon the drum G but not'in the path of the' projection H, and it extends therefrom preferably in the same direction as the chain (1, and its further end is secured to the periphcry of the sector E, which is pivoted at E to a suitable support or pedestal, E depending from the frame of the machine. The sector is formed with a slot, 0', extending from its circumference toward its pivotal point.

A rod, L, which extends nearly the length of the machine starts'from a point near the sector where its extremity is secured to the free end of the rock-arm 1, extending from a shaft, I, mounted in suitable hearings on sup-- ports M, attached to the frame.

Upon the rock-shafts are secured other arms. m, provided at'their outer ends with anti friction rollers, above which move in suitable guides vertical rods M, to the upper ends of which is secured the ring-rail D. A counterweight, m, is also mounted upon the rockshaft for the purpose of steadying and facilitating the movements of the parts. Only one rock-shaft and set of arms is herein shown, but in practice as many are used as may be necessary to properly support and control the movements of the vertical rods carrying the ring-rail, which latter may beof any desired length.

In a suitable slot, e, in the pedestal E is pivoted a rock-arm, J, provided atits upper end with a projecting pin or stud, L, which enters the slot e in the sector.

A rod, K, connected to the arm J and sector E by pin L is secured to the horizontal (halt-rod L,.and serves to communicate the motionofthesectorthertmand thencethrough the rock-arms and vertical rods, heretofore described, directly to the ring-rails.

The spindlesS are of well-known form, consisting of short metal rodstapered at their upper extremities, provided with drivingpulleys, and suitably stepped and journaled 0, that is formed with notches p at suitable intervals,within which theyarn is held and guided while being spun? This plate may be in the form of a continuous strip or be made in short sections. With either construction it is to be mounted upon, and preferably upon the lower side of a rail, 0, that is attached to the frame of the =machine by suitable hinges, so that the entire series may be simultaneously turned up out of the way of the spindles to allow the removal of the finished product or dofiing.

In many cases, for instance, when hardtwisted yarn is made, the guide-plateO is sufficient for all purposes; but when othervarieties of yarn are to be produced a more extended bearing is found necessary, and the supplemental guide-plate P, which may or may not be recessed, as desired, is attached to the upper side of the rail 0, This second plate should projecti'rom the rail far enough to occupy a position that will break the straight line into an angle that would oth erwise be formed in the yarn between the recesses in the plate 0 and the delivery-rollers.

These-guide-plates are essential to my apparatus when it is desired to produce what are known as .soft yarns, used for weaving purposes and the manufacture of hosiery. 1n suchcases I prefer to use two such plates, although a greater number may sometimes be used with advantage, by means of which the frictional strain upon the yarn between the delivery-rollers and the spindles'is materially lessened, thereby allowing the twist imparted by the spindle to run more freely to the bite ofthe rollers,whe're the untwisted sliverissues, thereby reducing the risk of breakage in the yarn and enabling me to spin on a bare spindle a-much softer yarn than it has ever before been possible to produce under such circumstances.

The notches p are flaring, and open directly forward, being widest at the edge of the plate P, as shown in Fig. 4, the advantage being that such notches produce much less friction upon the yarn, as they aflord fewer points of contact therewith, and in piecing up the yarn is much more readily placed therein than in any other form of guide known to me. This is of great importance in spinning the soft yarns above referred to, as the risk of breakage is diminished by the use of my improved guide-plate, and it is possible to spin a softer yarn with than without it. I

lilachines of the class herein described will, when the power is taken oil, usually run for some time before expending their llmmm t-m'! twist the yarn and upon which the twisted and coming to rest, during which period the speed of the spindles is so much reduced that the centrifugal force developed "is notsufficientto keep the yarn near the end of the spindle away from and out of actual contact therewith, the result being that before the machine stops several turns of yarn are wound around the point of the spindle, rendering it impossible to start the machine again without breaking anumber'of threads or-previously winding up by'hand theportion sovcoiled about the points of the spindles. In orderto obviate this difficulty, I provide brake mechanism for more speedily stopping themachinery, which mechanism, as shown, consists in a pulley, E secured to the. main orto the most convenient horizontal shaft of .the machinle, preferably to the shaft A vcarrying one of the tin' drums, A, and the fast and loose pulleys D D".

A curved-lever, A, is, pivoted to a suitable part of the frame on one side of the pulley E), and extending thereover is curved so as to correspond to and closely grasp the periphery,

means of which the brake-lever can be elevat-' ed. The lever A is preferably provided at that portion which comes in direct contact with the pulley with a removable liningor shoe, (1, which can be replaced'when'nec'essary. V y

' The belt-shifting lever D is provided with a stop or projection, 0 which engagesthe outer end of the horizontal lever B", which may be beveled, sloped, or. bent to facilitate its action. When the lever D is moved, so as to shift the belt from the fast to the loose pulley, the stop 0' is moved down the inclined end of the lever B, which rises, allowing the brake-lever A to drop into its operative position on the pulley E thereby bringing the entire mechanism speedily to rest. The reverse movement of the shifting-lever D" depresses the lever B, elevating its free end and raisingthe brake-lever A clear of the pulley E The action of the brake may be rendered faster or slower by a proper adjustment of the weight of the lever A, and it will be readily understood that the actualconstruction of the brake is capable of considerable modification without in any way departing from the spirit of my invention.

tion isas follows: A series of suitable :rings or hoops are provided, which rings are'mounted upon ahorizontal. rail adapted to be moved vertically to a greater 'orless extent by'means of the cam B, sliding plate. 0, drum G, sector E, suitable connections, and the system of levers thereto connected. The spindles that yarn is wound are so placed that each'passes vertically through its ring as the latter are moved up and down in the process of building the cop The mere proximity of ring and spindle accomplishes-nothing, and the wellknown arrangement whereby a traveler 0 mounted upon the periphery of a ring serves to guide the yarn to a bobbin on the spin'dle. I does not inany'essential respect resemble my method, which, .as-before stated,- "enablesme to wind a'm i 1le"cop on the harespindle of 7 a continuous spinning machine? "Thering's or hoops referred to are constructed of a strip 'of sheet metal or other suitable material, which may be continuous throughout either side ofthe machine, asindicated at 10,1 'ig. 8c 22, or in separate sections or p1ates, 11, to be afterward separatelysecured to their support-- ing rail D by bolts passing throughelongated.

adjusting apertures-12. The rail Dis preferably a bar of angle-irou which is carriedb'y the vertical rods M, which impart a'n ascending and descending motion thereto, which 'motion is by said bar-simultaneonsly communicated, to all the rings of a series. The said bar'may be of oth'erfmaterial thaniron, c and of any prefer red cross-section possessing the desired lightness and rigidity. I

Within suitable apertures'in' the strip 10' and plates 11 are placed linings orferrules 13, which may be of iron, steel, glass, porcelain, or any other material capable of presenting a smooth and durable surface. The ferrules may extend'above, below, or both above andlbelow the surfaces of their supporting-plates.- The saidferrules or linings may be placed loosely in the apertures. of the plates and held in posi tion by pins or equivalent means; but usually I prefer to fix them firmly in position by shrinkage, brazing, or other'well-known process, the ferrules themselves consisting of 10 short sections of tube, which, when inserted, form narrow raised edges on one or both sides of the plates, as show'n in Figs. 7, 8, and 21. In the latter instance, however, a plate, 14, similar to 11, but withoutthe ferrule 13, is placed below theplate which carries, the traveler, for a purpose hereinafter. explained. a I sometimes prefer to substitute for the platea-nd'ferrule a solid ring, -15,'which,is suitably a'pertu red.-to receive the spindle, and counter 1 15 sunk or cut away until it presents an edge, 16', of thedesired thickness, which edge; may or may'not, be fitted, with -a"fe rrul e, or may be formed so as to have sufficient of the material to answer thatpurpose; 'Ashank, 17,'p ro ectsfrom this-form of ring; by which it is-se:

cured in'position'on the rail D; I -In orderto effect the, spinning of the yarn,

,and also to cause-it to be'wound upon therapidl'y-rotated spindle, it is necessary-to in 12: terposea frictional device between the spindle and ring, which device 'is to'be' traversed by r the yarn being spun, and the tension or re sistance of'which varied according to the material operated upon, and-the hardness to which the bobbin or cop is tobe wound The tension device referred to consists, (as I sentially, in a small strip'of metal, 18, formed with bifurcated extremi-ties,;and of length exceeding the-diameter of the ring.

These travelers or drag-forks of various materials and in an infinite variety of shapes, a few of the equivalent forms thereof being shown in Figs. 7 to 21, inclusive, any of which will admit of the said drag-fork being sprung into position, with its ends embracing the periphery of the ferrule or ring, as, for instance, as shown in Fig. 8, and the bifurcations referred to shouldbe sufficiently extensive, whatever their particular configuration, that the device may, as a whole, be capable of the greatest freedom of movement within its ring. One end of the drag-fork maintains about the same position with respect to the periphery of the ring and the yarnentering at that end on its way from the guide-plates to the spindle. It is called the eye, from which the yarn passes along the central portion or ridge of the traveler, and thence between the prongs of the delivery end or fork, and inward to the spindle.

- The tendency of the loosely-hung drag-fork tension device is to lie close to the spindle, or whatever portion of the cop may be thereupon, and it must therefore be of such lightness that the strength of the yarn to be produced is sufficient to overcome its inertia, the result being that when the spindle is in motion the fork will be presented thereto and the bridge brought into actual contact therewith, (or with the cop,) and the said bridge affording the necessary fulcrum, the draft of the yarn passing through the fork will send the eye travel ing around the ring at a speed not quite as high as that of the spindle, and the yarn coming to the said eye will receive rotary motion therefrom, and so be spun or twisted to the desired extent.

The rotary movement of the drag-fork being entirely due to the friction of the yarn traversing it from eye to spindle, the said traveler must be very light to be so affected;

- and one of the most important features of this part of my invention consists in so proportioning (adjusting) the weight (size) of the drag-fork to the work that the friction of the yarn thereupon will not be suflicient to probare spindles. This object I accomplish withpel it around the ring at the same speed as that of the spindle, and that it will lag behind to a predetermined and desired extent, the effect of which will be that during the process of spinning the yarn is also continu ously wound upon the spindles in the ratio of the difference in speed between the spindle and traveler, making a harder or softer cop, according to the weight of the drag-fork used, or coils of yarn around the same, without breaking the yarn by excess of friction, and at the same time rendering continuous the operations of spinning'and winding onto the I travelers or drag-wi-resthat. are not necessarily incasedincohtaiuersybr in a box or grooved ring or their substitutes, as is the case with other attempts made in the direction of spinning on the bare spindles on continuous spinning-frames. Moreover, our drag 15, and 18-are provided with additional projections, q, through or around which the yarn is passed on its way from the eye to the spirr dle, which will hai e the effect of increasing the tension between the traveler and the cop or spindle, thereby lessening it between the said traveler and the delivery-rollers.

A modified form of the above is shown in Figs. 12, 16, 17, 18. These latter do not take the spindle directly as their fulcrum; but they make the line of yarn or outer line of yarn serve that purpose. This takes place in travelers such as shown in Figs. 12, 17, and 18, one end thereof being loosely held by the ring or ferrule by means of small projections or hooks g at the extremity of the eye, and the bridge leading from this eye to the fork-shaped end of the traveler is so proportioned in length as to lead the yarn passing through the fork direct to theperiphery of the spindle or dispose the coils or layers of yarn over a longer portion of the body of the cop, which variation of traverse causes the yarn to be more strongly united and bound together, producing a cop that will bear handling after it is removed from the spindle.

One object of my invention being to dispense entirely with the wooden bobbins ordinarily used in maeliines'of the class described, the oops I produce must be, and are, self-sustain ing, which result is attained by means of the mechanism already described, the operation whereof is substantially as follows:

7 The fork a being moved to its starting-point at the extreme inner end of the plate C-that is, nearest to the drum G-by backward rotation of the screw-shaft 0*, the chain (P will be wound on the drum,Gto its fullest extent,

passing at the latter portion of its stroke over the projection H, in passing over which the chain will be taken up to any desired extent, and the movement of the drum itself very much retarded. While the chain itself is moved similarly at each stroke during the time when it passes over the said projection H, the action of the drum G is retarded or delayed, thereby checking the downward movement of the ring-rail at the desired point,and causing more yarn to be there deposited. In practice, this effect upon the ring-rail is sought at the lower portion of the earlier part of its traverse, so as to form a neatly-rounded cop'- bottom containing a law; quantity of yarnnot inconveniently liable in handling.

As the work progresses the step-by step rotation of the screw pushes back the fork d and gradually rotates the drum G, so that beslip and unravel fore the cop is quite half wound the extension H has, by the gradual rotation of the drum G, passed out of reach of the chain (1 and entirely out of action,after which the movement of the ring-rail is even and regular; but for the purpose of distributing the yarn over a longer portion of the middle of the cop, the distance through which the sector moves, its system of levers, and through them the ring-rail, first gradually increases until'the cop is somewhat more than half built, and then as gradually decreases until the cop is finished.

At starting, the sector E is in its extreme forward position-that is, farthest from the drum G-where it is rocked upon its bearing,

. through only a portion of its range of movement,

by the reciprocations of the plate 0, and as the sector changes position and moves more nearly in a vertical plane, its effect upon the system of levers and ring-rail through the pin L, pivoted arm J, connecting-rods, and rockarms increases, and becomes greatest when at the central portion of its stroke the arm J stands in a vertical position. Up to this point the movement of the system of levers and the traverse of the ring-rail is constantly on the increase, and after passing beyond this stage, which should include the central'and otherwise weakest portion of the bobbinless cop, the angle at which the pin L moves in the slot 0 becomes greater at each stroke, and a considerable portion of the effect of the movement imparted by the sector to the drum J and connections is thus intentionally neutralized,and thereby the movement communicated through the said system of levers to the ring-rail is gradually decreased until it becomes practically the same as at starting.

end a squared projection adapted to fit a corresponding aperture in the axis of the drum G, and when the cops are finished said lever is placed in position, the chain d is detached, and by turning said drum the ring-rails are moved downward while the machine-is in motion, whereby any desired number of turns of yarn can be wound obliquely onto the outside of the finished cop for the purpose of giving. it additional strength and preventing injury thereto. Having thus broughtthe rails to their lowest point, a few turns of yarn are now allowed to accumulate upon the bare spindles to form the nucleus for the next cop. The machine can then be stopped and the tinished product removed, leaving it in every respect ready for starting, when it will automatically repeat the above-described operaiions.
