' cation.

This invention relates to machines for spinning, doubling, and twisting yarns or threads of fibrous substances; and it consists in so constructing the spindles or parts in connection therewith that they are enabled .to perform their functions at a considerably- .increased rate of speed as compared with others of the same classes, and the resultant yarns are more even in thickness and smoother than are those as heretofore produced. The spindles or other parts are further rotated at a variable rate of speed, as is required when winding the yarns on the varied diameters of cops or bobbins mounted on said spindles.

To attain the object of this invention, I make use of devices constructed and arranged as hereinafter described and as illustrated by the accompanying drawings, in which Figure 1 is a sectional end elevation of a sufficient portion of a spinning or twisting machine to illustrate the application thereto of my improvements. Fig. 2 is front elevation thereof. Fig. 3 is elevation of parts illustrated by Figs. 1 and 2 as seen in the direction indicated by the arrow A, Fig. 1. Fig. 4 is plan of certain parts shown by Figs. 1, 2, and 3. Fig. 5 is sectional end elevation of a portion of a spinning-machine drawn to a reduced scale and shows the method of driving the spindles and rings mounted in connection therewith, as hereinafter referred to. Fig. 6 is plan of parts illustrated by Fig. 5. Figs. 7 and 8 are similar views to Figs. 5 and 6, respectively, but illustrate a modification thereof. Fig. 9 is sectional elevation, drawn to an enlarged scale, of a spindle and ring -mounted in connection therewith.

Similar letters of reference indicate similar parts throughout the several views.

thereon) by pegs or projections a on said disks taking within openings formed in the lower ends of said bobbins d in the usual manner. The rings 6, which have conical-shaped extensions 6 are mounted upon sleeves 6, fixed upon the stationary railf by the bolts f taking through the parts 6 of said sleeves. The rings 6 have said conical-shaped extensions in order that by the driving bands or tapes 6 which pass thereover, being raised or lowered thereon they may be rotated at a variable rate of speed. Antifriction ballbearings e are arranged to intervene between the rings 2 and the parts e of the sleeves e, and the upper ends of'the sleeves e are arranged to be slightly higher than those of the rings 6, so as to be about level with the travelers 9, carried by said rings 6.

Hence they act as guards or guides for the I yarns as they pass from the travelers g to the bobbins d, or instead of these sleeves 6 being extended, as described, their upper edges may be lower than those of said rings 6, and loose or detachable sleeves or guards may be employed for this purpose. They are held in position by taking over or upon the upper ends of said sleeves e.

The driving-bands e which take around the parts a to transmit motion to the rings 6, are raised and lowered by means of the pulleys h, which are mounted on the shaft h, carried by brackets k fixed upon the vertical rod it. Mounted upon this latter are arms is connected to the horizontally-movable bar m through the chain 70*. The bar m derives its movements from the cam m through the medium of the bar a and screw n. The cam m is mounted upon the shaft m by a key and keyway, so asto be capable of movement thereover while being driven thereby, the extent of the movement of said bar n being varied by the combined lateral and rotary movements of said cam m. The shaft 'm, is or may be the shaft which operates the ordinary lifter-motion of the machine. The lateral movements of the cam m are automatically effected by the screwed shaft 0, which is rotated through the gearwheels 0 0 and takes through the nut 0 The screwed shaft 0 has a plain part formed on it, so that after it has traversed the cam m for a certain distance laterally it will go out of gear with the nut 0 Hence although the rotary movements of the cam m and shaft 0 are continued said cam will be stationary laterally. The gear-wheel 0 is formed integrally with the cam m, and the wheel 0 is fixed upon the screwed shaft 0. It will thus be seen that as the screwed shaft 0 is rotated from the shaft m through said wheels 0 0 it will move longitudinally through the internally-threaded nut 0 and will carry the wheel 0 and cam m with it by means of the projecting part or shroud 0 until it has reached a position where it goes out of gear or is disengaged from said nut 0 as and for the purpose hereinafter described. The cam g, which is also fixed upon the shaft m is the ordinary and well-known cam for raising and lowering the lifter-rail I) through the ordinary connections, so as to regulate the positions of the coils of yarn upon the bobbins d. -The large end of the cam m is of the same shape as this cam g, so that when these two are rotating with the largest diameter of the cam m in contact with the bar 01, they respec* tively raise and lower the driving-bands e and the lifter rail 1) simultaneously and through equal distances.

At the commencement of the winding of the yarns on a series of bobbins the bar n is opposite to the part of the cam m of least diameter, and during the formation of the heel of the bobbin the cam m is gradually moved horizontally to vary the traverse of .the bar n,and consequently that of the tapes or bands e However, on the completion of said heel part-that is, when the coils of yarn are being wound from the largest to the smallest diameter or for or during the full traverse of the machinethe cam m will have reached a position wherein its largest diameter is opposite to the bar n, at which time the screw 0 is arranged to go out of gear with the nut 0 by having a plain part thereon, as above described. Hence the cam m will remain in this position laterally during the remainder of the winding operations, thus transmitting a regular movement to the driving-bands e during each traverse of the machine. In order to enable the screwed shaft 0 to be re turned to its normal position after the completion of a set or series of bobbins, I fix thereon a hand-wheel 0 and also hinge the bearings p, carryingthe nut 0 at p to the bracket 10 The bearings 10 are retained in the position wherein the wheels 0 and 0 are in gear by means of the handle or lever 12 connected thereto, being held in the position shown by Fig. 1 by the swiveling-catch p However, on said catch p being moved away from said lever 10 the shaft 0 and wheel 0 fall, so that the latter is out of gear with the wheel 0 after which the screwed shaft 0 may be rotated by the wheel 0 in the reverse direction to that required for traversing the cam m, as hereinbefore described. The wheel 0 will also carry with it laterally the wheel 0 and cam m by means of the projecting part or shroud 0", after which the wheel 0 is raised into gear with the wheel 0 by the lever 11 so as to be in position for recommencing its operations. The traversing of the bands or tapes over the rings may further be regulated by means of the screw n, upon which is mounted the hand-wheel 1". This screw meshes with a similar one formed in the bar n, and its end takes against the bar m. Hence the position of these two bars relatively with each other may be adjusted or regulated, so that the traversing of the tapes or bands 6 may be arranged to be over any particular part of the rings e.

l I arrange the spindle a and ring e for each bobbin d to be driven by the same band or tape 6 so that should there be any inequalities or slackness in the latter the rate of speed of both of the former will be equally affected thereby, and I further cause said band or tape 6 to drive two, four, or a greater number of spindles on each side of the machine, as shown by Figs. 5, 6, 7 and 8. In the arrangement illustrated by Figs. 5 and 6, starting from the point E, the band or tape 0 passes in the direction indicated by the arrows around the rings (2 e beneath and partially around the drum or cylinder 8, around the whirls c c, beneath the cylinder 8, then around the whirls 0 0 again partially around the cylinder 8, over the tension pulley s, then around the rings e 6 to the point E. In the modified form shown by Figs. 7 and 8, commencing at the point F, the band 6 passes around the whirls c 0 beneath the cylinder 8, around the whirls c 0 over the tension-pulley s,'around the cylinder 8, then around the rings e e and e 6 back to the point F.

It will be readily understood that I may make use of more than one tension-pulley s for each band or tape and that I may mount them in any appropriate positions.

Brake parts 2 2 are mounted upon the rods 2 between the spindles a, as shown by Figs. 1 and 2, to operate upon the rings e and whirls 0, respectively. The rods 2 are mounted in bearings 2 z, loose bushes being arranged in the latter when said rods are square in crosssection. The brake parts 2 z are operated by the projectin pieces 2 Having thus described the nature and object of my said invention, what I claim is 1. In machines of the class described, rotatably-mounted rings having means for the support of travelers to operate in connection therewith, and having conical-shaped extensions to be engaged by suitable drivingbands, whereby said rings may be rotated at a variable speed according to the vertical position of said bands relatively to the extensions.

2. In machines of the class described, rings having extensions of conical shape, travelers operating in connection therewith, mechanism for traversing the driving bands or tapes over said extensions, and means for adjustthereon, rotating rings and travelers mounted in contiguity therewith, a driving-cylinder, and bands or tapes connecting said cy1- inder, spindle-whirls and rotating rings in such a manner that one tape or band drives one, two or more spindles and rings on each side-of themachine, substantially as herein specified.

In testimony whereof I have afiixed my signature in presence of two witnesses.
