Application filed September 24, 1881. Serial No. 42,469. (Model) Patented in Germany March 19, 1880, No. 11,976; in England December 2, 1880, No. 5,029, and in Austria-Hungary January 11, 1882, No. 32,035 and N0. 371.

T aZZ whom it may concern:

Be it known that I, JEAN JACQUES BOUR- CART, civil engineer, of Zurich, Swiss Gonfederation, have invented Improvements in Ring-Spinning Frames; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed sheets of drawings, I have received German Letters Patent for said invention, dated March 19, 1880, No. 11,976, and English Letters Patent, dated December 2, 1880, No.

This invention relates to certain improvements in ring-spinning frames, fully describe d hereinafter, whereby to insure a regular twist, facilitate the operations, and overcome certain defects incidental to ordinary constructions.

In the accompanying drawings, Figure 1 is a front elevation of part of a ring-spinning frame embodying my improvements. Fig. 2 is a side elevation, in part section on the line m, Fig. 1. Fig. 3 is a detached sectional. elevation showing one of the spindles, supporting-rails, and ring, ring support and guide, and modified form of a step, wharve, and fric- -tion-disk. Fig. 4 is an enlarged sectional two series supported by rails G D and O and D, the rails (3 D being above and back of the rails 0 D so that the rear spindles are higher than the front spindles. Each spindle turns at its lower end in a step, C", and extends through the upper rail and through a long tube or bolster, 0, supported by the said upper rail.

Upon the spindle, above the foot-step bearing, are friction disks 1) b the lower forming part of the wharve D, and in the modified forms shown in Figs. 3 and 4 provided with a tube, m, revolving in or on a tubular extension, e, of the step. The upper friction-disk is secured to the spindle, and a washer, if, of cloth, india-rubber, or other friction material, is preferably placed between the disks. By this construction, if an excessive traction is exerted on the spindle it is able to yield a little,because its foot is not rigidly held in its step, and the slipping of the upper disk, 1), upon the lower disk, b, permits this play of the spindle D, which, however, tends to return to its position central with the axis of the step as soon as the traction is removed, this tendency resulting from p the rapid motion of the spindle imparted by the frictional contact of the disk b with the rapidly-revolving driving-wharves. The frictional connection between the spindle and the wharve also prevents too sudden movement of the spindle in starting or stopping.

As the ,wharve D has its bearing in the tubular part of the step, and as the spindle is n t in direct contact with the tube m of the wharve, any lateral draft upon the wharve will not affect the spindle or throw it from its central position or increase the friction. The driving drum or cylinder F is secured to the driving-shaft X, turning in bearings upon the frame of the machine, and one series of bands,

1), pass round the driving-cylinder and beneath a guidecylinder, D to the wharves of the upper spindles, and another series of bands, 1), pass round the driving-cylinder and beneath guiding-cylinders D D to the wharves of the lower spindles.

To the end of a loose sleeve, m on the driving-shaft is secured a pulley, K, and to the shaft X is secured a pulley, K and upon the end of the shaft X turns an idler-pulley, K so that by shifting the driving-belt Z onto the pulley K the cylinder may be rotated, by shifting it onto the pulley K the sleeve m is rotated without moving the cylinder,while by shifting it onto the idler-pulley the movements of all parts of the machine are arrested. The bolster G not only steadies the spindle at a point a considerable distance above its step, but also supports a circular block, of, which serves as a guide for a tube or cylinder, 0, carrying the usualring,t,at the upper end,and having at the lower end an annular bearing, through which the bolster passes, so that the said tube slides upon the said bolster and guide-block, a feather or pin, 0 upon the tube 0, extending into a vertical slot, G, in the bolster, so as to permit the said sliding movement, but prevent any rotation of the tube. A traveler, t, is carried by each ring t, and the yarn passes through thesame to the spindle, as usual. It is requisite to impart to each ring not only an ascending and descending movement, necessary for winding on a 7 layer of yarn, but also a varying ascending movement for the purpose of building up the body of the cop. These movements are derived from the rotation of the drivingpulleys through the medium of devices which will now be described. The reciprocating motion of the tube Ois imparted from a cam, E,which acts upon an arm, n, projecting from a rockshaft, O, and the arm operates through the shaft and intermediate gears, E E E E, upon a shaft, 0, having a pinion, c, gearing with a rack-bar, O, at the rear side of the tube 0. WVhen there are two series of tubes 0, there aretwo shafts, the upper shaft, 0', before referred to, and a lower shaft, 0, each of which carries a piniongearing with a rackbar upon each tube 0. The shaft 0 carries a pinion, E, between which and the gears E intervenes a gear, E. The gear E is carried by a sleeve, 0, turning loosely upon the shaft 0, and carrying a worm-wheel, E.

I To the rock-shaft O is secured a frame, E, from which projects an arm, E", and which carries a shaft, E having on it a worm, e, and a ratchetwheel, E the worm gearing with the wheel E, and the ratchet'engaging with a pawl, 6 hung to the frame of the machine. (See Fig. 1.) As the worm locks with the worm-wheel,the vibration of the aim n will carry with it the gear E although the latter is loose on the shaft 0, because the worm engages the teeth of the worm-wheel, so that as the arm n is lifted by the rotation of the cam E in the direction of its arrow, Fig. 2, both of the shafts O and 0 will be turned so as to carry downward the ring-tubes O, which motion will lay the yarn on the cop, and as the shoulder w of the cam passes from beneath the end of the arm n, and the latter swings downward, the ring-tubes will rise more rapidly than they descended,thereby carrying the yarn spirally over the last layer to the top of the cop. As each layer of yarn should be laid above that below it in the manner required in the usual building up of a cop, it is necessary that the ring shall be lifted at each movement a little farther than upon the proceeding movement and shall descend to a slightly less extent. This movementis effected through the mediumofthe sleeve 0, worm e", worm-wheel E", ratchetwheel E and pawl 6 The upward rocking movement of the frame E brings the ratchet-- wheel E against the pawl, which causes the wheel and worm to be rotated to a slight extent, thereby rotating the wheel E, and, through the intermediate gears, the shafts 0 and 0 sufficiently to lift the tubes slightly in excess of the lifting effected by the regular rocking movement of the shaft, the descent being correspondingly limited. The extent to which this regular upward feed of the rings is effected may of course be regulated by setting the pawl so as to secure a greater or less movement of the ratchetwheel. The rapid downward movement of the arm n is facilitated and insured by a spring, e, connected at the lower end to the frame of the machine and at the upper end to the end of the arm E". Each pinion c bears on a collar, 0 and is secured to a loose sleeve, 0 which turns loosely upon the pinion-shaft, and has a serrated end adapted to the serrated end of a second sleeve, 0*, which turns with but slides upon the shaft, and is carried toward the sleeve 0 by the action of a spring, 0, these devices constituting a clutch, which, under ordinary circumstances, will insure the rotation of the pinion c with the shaft, but which will permit the said pinion c to rotate when an excessive pressure is brought to bear upon the tube 0 to carry the latter downward. Each ring is thus rendered independently adjustable, so that access may at any time be had to any one of the cops without interfering with the position of its ring in respect to the others, while the varied rise and fall and uniform gradual ascent of all the rings are effected.

In continuous spinning it is very desirable that the movements of the drawing-rollers shall be arrested at certain periods. Inasmuch as the winding on is effected during a continuous delivery of the yarn, there will be formed at the end of the rise of the ring an accumulation of yarn on the end of the cop that is,tw0 or morelayers ofyarn will be wound on the same spot. This is prevented if the delivery is stopped for an instant when the ring completes its rise.

The intermittent action of the drawing-rolls necessary to secure these results is effected by throwing the drawing-roller shaft temporarily out of gear or connection with the other de-' vices. One mode of effecting this will now be described: A vertical shaft, 7, is provided with a worm-wheel, 9 which gears with a worm, 9, upon the sleeve m and a bevelpinion, a, upon the shaft y meshes with a bevel-wheel, E upon the shaft a of the cam E, so that the said cam is rotated from the rotation of the sleeve m which is carried around with the pulley K. The drawingroller shaft 9' is driven from the shaft 3/ through the medium of a short shaft, 9 bevel-gears g g g g, a shaft, 9, and a clutch device whereby the shaft y may be thrown into and out of connection with the shaft 9 As shown, the clutch device consists of a serrated enlargement, a, of the shaft 9, and a serrated enlargement, 3 on a sleeve, 3/, which slides upon but turns with the shafti and is grooved to receive the forks of a shifting-lever, y, pivoted to the frame of the machine and connected to a rod, y which has at the lower end an elongated slot or eye, 4;, receiving a pin, 3 projecting from the arm E The pin and the slot 1) are so arranged that as the arm E approaches the limit of its movement in either direction the pin will be brought against one or the other end of the slot, and the clutchsleeve 3 will be thrown into or out of connection with the other portion of the clutch device. Thus as the ring completes its ascent the pin y is brought against the lower end of the slot, and the clutch-sleeve is drawn down, so that the feed of the yarn is arrested. The arrest of the action of the drawing-rollers at the time that the ring reaches the termination of its upper movement prevents the accumulation of the yarn at the point of the cop. The moment the rings begin to descend the pin 3 begins to rise, and a counter weight, W on the end of the shiftinglever lifts the clutch-sleeve, so as'to throw the shafts y and 9 into gear, and start the action of the drawing-rollers.

In machines of ordinary construction the drawing-rollers, spindles, and travelers are simultaneously put in motion, the result being that many yarns are broken or weak places are produced-effects which are prevented in the above-described machine by first starting the spindle by throwing the belt Z onto the pulley K, and then starting the drawing-rolls by further shifting the belt so as to operate on both pulleys K K, the belt being as wide as the combined faces of the pulleys K K and the arrangement of pulleys and connections described permitting this action.

To assist the winding on, I place upon the spindle D, above the upper end of the bolster, a cup or disk carrier, V, (which may be of any of the forms shown in Figs. 5 to 11,) the yarn being conducted to the spindle from the traveler, when the latter is near its lowest position over the edge of said carrier, or in contact with a shoulder or part thereof, as shown in Figs. 10 and 11. The yarn in passing from the traveler to the spindle rubs'against the carrier, and is carried round thereby as soon as the spindle begins to revolve, thus avoiding a sudden tension, apt to result when the rotation of the spindle alone is depended upon to start the yarn in motion, and which frequently causes the yarn to break without starting the movement of the traveler.

The carrier may be fixed to the spindle, as shown in Figs. 7 and 9, or it may bear frictionally on the spindle or on ashoulder thereof, as shown in Figs. 9 to 12; and to prevent the slipping of the yarn too readily the carrier may be provided with notches or shoulders, so as to present faces or bearings which insure the movement of the yarn as the carrier begins to revolve, as in Fig. 11.

The device further serves as a means of underwinding the yarn when the ring is carried to its lowest position prior to doffing the bobbin, the yarn then lapping round the carrier V, in which it is assisted by the notches or bearings before described, and being broken between the cop and carrier when the cop is removed, the end being thus retained ready for a fresh bobbin.

In Fig. 4 is illustrated a modification in which the spindle D turns in a long step, and the tube on of the wharve D incloses the tube 6 of the step, and the ring tis carried by a ring-rail. In this case the wharve has an independent bearing, as before, so that no strain comes on the spindle.
