TWISTING ATTACHMENT FOR WINDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 499,666, dated une 13, 1893.

Application filed August 6,1892.

'upon a suitable yarn receiver.

I have chosen to illustrate my present invention as applied to a spooling machine of a form heretofore patented to me, No. 404,831, June 11, 1889, and in the drawings the driving drum or shell roll is represented for convenience as having its axis parallel to the side of the frame, but this is immaterial, and instead, the said drum or roll may stand at right angles thereto as in United States Patents Nos. 459,039 and 459,040.

Prior to my invention it has been customary to take cops of yarn and without twisting, wind the yarn, one or more strands upon a spool, and these spools having the yarns so applied have been put into a twister and two or more of said yarns have been twisted together by or through a spindle, but in my invention, the yarn on the cops or bobbins on which they were spun are doubled and twisted and wound in one operation on yarn carriers, such as spools or cones.

Figure 1, in vertical section and elevation represents a sufficient portion of a spooling machine with my present improvements added to enable myinvention to be understood; Fig. 2, an enlarged vertical section of my improved doubling and twisting device detached from the machine. Fig. 3, is a view looking down on Fig. 2, below the dotted line as. Fig. 4, is a View looking up from the dotted line 00; and Fig. 5, is a detail to be referred to.

The frame-work A, the cylinder 6 on the shaft 6 the shaft e having suitable wheels e and located within the shell roll h constituting a driving drum to rotate the yarn receiver a are and may be all substantially as in the patent referred to, said yarn receiver being SerialNo. 442,333- (No model.)

either cylindrical or conical, or of any known and suitable construction, but instead of the shell roll, I might employ a solid drum. I have herein shown but one driving drum,but it will be understood that a machine embodying myinvention will contain aseries of said drums along one or both sides, and when the said drums are used parallel to the side of the frame, the wheels e for rotating them, may all be arranged on one and the same shaft 6 arranged lengthwise of the machine, and driven in any usual or suitable manner. My patent of the United States, No. 404,831, shows one plan of driving shafts suitable for rotating said drums when their axes are at right angles to the side of the frame. The traverse guide 72 will preferably be of the form represented in United States Patent No. 459,039, it having a foot to enter a crossing groove in the shell roll it constituting the drum, said guide sliding on rods 2, 2, sup ported by suitable arms or brackets as 3 suitably attached to the frame-work A. The lower girth A of the frame has connected to, or is provided with a bracket a, which latter supports a stand a on which is a stud a which serves as a support for a pulley a preferably having a surface by which to frictionally engage and rotate the head a carrying the spindles a two or more of said spindles containing and presenting the yarns to be twisted and wound intospoolform,the drawings representing the said yarns as in the form of cops as when taken from a mule. The head at its lower side is shown'as provided with a friction face a which may be of cloth, leather, india-rubber, or other usual material. The hub of the pulley a is represented as provided with a belt pulley a which receives the belt a deriving its motion from the cylinder 6 The bracket and stand are represented as confined together by a hollow stud I) having a shoulder to rest on the bracket, a nut b being shown as screwed upon the lower threaded end of the stud. This stud receives through it a stop-motion rod 0, and near its lower end the stud has a transverse opening for the reception of a pawl c, the pawl being represented as connected adjnstably with the rod 0 by a suitable screw o The outer end of the pawl c engagesalit'terc mounted loosely on a stud c, said lifter being so constructed that when turned on or about the stud, the lifter, the shape of which is shown by dotted lines Fig. 1, will act by one of its corners or by its surface to lift the head a. from the wheel a and thus stop the rotation of the head with its spindles, or yarn holders. This lifting device is represented as a disk or button having a portion of its periphery slabbed oif as in Figs. 1 and 5, leaving two corners 4, 4, see Fig. 5. The head a has, as shown, a hollow hub 5 which receives a tube cl, which at its upper end supports a disk 61' having its periphery incased by a clearer 61 preferably a piece of cloth, the purpose of which is by its action against the yarn to give tension thereto between the rigid guide eye 61 below the disk, one eye for each yarn, and the eye 6 above the disk, the latter eye being carried by a drop leverfpivoted at f on a suitable stud f in the disk. The stop-motion rod has fast on ita collar 9, see Fig. 2, the collar serving to limit the descent of the rod, and above the collar, the rod has applied to it frictionally a clutch 9 provided with depending pins or projections 8. This clutch rests at its lower side on the collar, and the pins lie outside the collar and in the line of movement of the inner ends of the drop leversf, but when a yarn going to the guide eye f breaks so as to let a drop wire fall, then in such case the inner end of the drop wire as the disk rotates meets a pin next to it of the clutch and acting against the said pin rotates the said clutch, and with it the stop-motion rod 0 far enough to turn the lifting device 0 and break the driving contact between the head a and wheel a Above the clutch the rod 0 is provided with a friction device g shown as a piece of leather or other suitable f material held against the clutch by suitable devices as nuts. The yarn to be doubled and twisted is led from the eyes 6 to the station-, ary eyes f 4 and thence preferably over a glass rod m to the traverse device h before described.

From the foregoing it will be understood that the doubling and twisting devices, shown detached in Figs. 2, 3 and 4, may be readily attached to a spoolin g machine so that the yarns carried by the attachment, may be doubled and twisted on their way to the spools. It will be understood that should the driving drum be at right angles to the side frame as in Patent No. 459,039, that in such event the yarn will have to be presented to the eye of the traverse guide, as in United States Pat- ,ent No. 404,831.

is permitted to slip to thereby avoid breaking the pins of the clutches.

shell roll form of drum is the best form known to me. a

By the term cop as used in the claim I intend to include a wound mass of yarn on a bobbin or tube.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A hollow spindle; a rotating head connected thereto; a series of spindles fixed on said head and adapted to receive and hold masses of yarn taken directly from the spindle of a spinning machine; a device to rotate said head; a series of drop levers; a hollow stud to support said spindle, a drop rod extended through said spindle and stud, and devices actuated by said rod to arrest the rotation of said head, combined with a spooling mechanism consisting essentially of a drum to rotate the spool or device upon which the twisted yarn is to be wound, and a traverse mechanism whereby the spun yarns may be directlydoubled, twisted and wound all at a single operation, substantially as described.

2. The rotary driving drum of a spooling machine, and its co-operating traverse guide, combined with a rotating head adapted to receive and carry masses of yarn taken directly from a spinning machine; a hollow spindle upon which said head is mounted; a stop motion rod extended through said spindle; a lifter adapted to be actuated from said rod; and drop levers to control the movement of said rod, the combination being and operating substantially as described, whereby upon the breaking of a yarn the lifting device stops the rotation of the head, substantially as described.

3. The rotating head, the hollow stud about which it rotates, a connected disk having drop wires, and means to rotate said head, combined with a lifting device to lift the rotating head from its actuating means, a stop rod, a clutch thereon,and means between the said stop-rod and lifting device, to operate, substantially as described.

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

JOHN WV. FOSTER.
