JOSEPH KING, OF KEIGHLEY, ENG-LAND.

SPECIFICATION forming part of Letters Patent No. 759,721, dated May 10, 1904. Application filed May 2, 1903. Serial No.155,249. (N model.)

I To all whom it may concern:

Be it known that I, J osnrn KING, a subject of the King of Great Britain, and a resident of N o. 43 Clifi'e street, Keighley, in the county of York, England, have invented a certain new and Improved Machine for Winding Yarns or Threads of Fibrous Substances, of which the following description is a specification.

In the winding of yarns or threads of fibrous substances which are delicate, tender, or fragile, as is especially the case with certain classes of yarns that have been subjected to a polishing process, which further tends to make the coils of threads adhere together, it has been heretofore found impossible to effect such winding direct from the hank or skein onto a pirn or bobbin by reason of the yarn on being subjected to the irregular pull or tension thereon incident to such winding operations being broken and entangled. As is well known, in certain types of machines in the winding of yarns onto pirns or bobbins said yarns are caused to travel at an irregular speed from the position of delivery until finally wound into position, at one time passing quickly when being wound upon the larger part of the pirn or bobbin and at another time more slowly when being wound upon the smaller part of the pirn or bobbin, and these changes of speed are of very frequent occurrence, since in the building of the coils of yarn onto the pirn or bobbin they have to be wound to cross and recross each other very often in order that when the winding operations are completed all the coils of yarn are firmly and evenly placed in position one upon another, so that they are enabled to keep each other in their said positions and not become detached and entangled, thus to be wasted, as is but too well understood. To overcome these defects by producing mechanism that will keep the yarns or threads at even tensions throughout the whole of their winding operations is the object of my present invention.

The accompanying drawings are illustrative of machinery made in accordance with my invention.

Figure 1 is an end elevation of a machine for winding yarns or threads constructed in accordance with my invention. Fig. 2 is a transverse section of said machine. Fig. 3 is a plan, as seen from above, of a portion of said machine. Fig. 4. is a front elevation of a portion of the machine.

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

The hanks or skeins of yarn are mounted upon a reel or swift a of very light construction, as the drag thereon must be little as possible. The thread or yarn Z) is placed simultaneously over the swift a and the tensionregulating device, which latter consists of the weighted lever 12, pivoted at (Z, said yarn being guided by forks 0. As it leaves the swifts the yarn passes over the thread-guides a j" to the pirn or bobbin which is mounted in a well-known manner to rest between and be supported by the rotary rollers 7, while rotary motion is transmitted to it by the spindle l, driven by the band m from the drum or cylinder a. r

The spindle l1: and rollers are mounted upon cross rails or supports 7', the pirn or bobbin g being mounted upon the spindle in such manner as to have a longitudinal movement thereon independent of the movement of said rails or supports. The rollers /t are tapering or conical in form and by their arraugement form a corresponding conical or tapering socket around the pirn or bobbin. The rails or supports '1' are arranged to slide upon the framework A, so that the rotation of cam s will effect the reciprocation of the levers t and u, and a corresponding vertical reciprocation is imparted to the rails or supports 9', and consequently to the spindles 71:, pirns g, and rollers 70. The rising and falling motion of the pirns is through a space equal to that on the pirn between the largest diameter of coils thereon and the smallest. Thus when the yarn has to be wound on the smallest part of the pirn (which in this case is below the larger part) the spindles and their pirns will be lifted to their positions, from which they will gradually descend until their larger parts are brought into position opposite the guides f to have said yarns wound thereon. In this manner this is effected without requiring any movement of said threadguides to produce what is known as the building of the pirn. Consequently their effect upon the tension of the yarns or threads remains always the same. As the pirn is built up by the feed of the yarn the pressure of the latter against the conical walls of the rollers it will cause said pirn to move upwardly independent of the reciprocation of the rails, and said pirn is thus completely and evenly Wound.

The swift a, lever 0, and thread-guide e are mounted on the bar p, which slides in bearings q, in order that said swift a and other parts may be drawn entirely clear of the adjoining parts of the machine when it is desired to place a new hank or skein on said swift a, as shown in broken lines Fig. 2.

The arrangement of the weighted lever c is such that provided the threads adhere together it is temporarily brought into the position shown in broken lines, Fig. 2, when the sticking threads are drawn apart and the op erations proceed.

To prevent the threads or yarns from traveling at variable speeds by reason of being wound on said varied diameters of the pirns or bobbins, I arrange the driving-cylinder n to be rotated 'at a variable speed-that is to say, when the pirns g are in their lowest positions the cylinder at will transmit a slower rotary motion thereto, while when they are in their raised positions the speed of such rotary motion will be increasedand the varied rates of speed are regulated to be distinctly in proportion to the respective sizes of the pirns in order that the fewer turns or revolutions of the larger parts of. the pirns may Wind thereon exactly as much yarn or thread as is wound upon the smaller parts of said pirns when they are rotated an increased number of revolutions.

The variable speeds of the cylinder n are effected by the wheel 1 rotating about the enlarged pivotal bearings 2, eccentrically in which is mounted the shaft 3, deriving its motion from the lever 4, into the slot in which takes the pin or antifriction-bowl 5, carried by the arm of the wheel 1. Thus at one part a greater and at another part a lesser speed is transmitted to the shaft 3, the rotary motion of which is transmitted by the gearing-wheels 6 7 to the cylinder a.

In practice the hanks of yarn are taken from the machine where they have been wound or formed during the polishing process and are placed upon the swifts a. To accomplish this, the weighted lever c is moved so that the arm or bobbin thereof over which the hank has to take is pressed into contiguity with the periphery of the swift. After the yarn has thus been passed over the swift and lever-arm the lever 0 moves by its weight, so as to put the necessary tension on the yarns. The process of polishing to which the yarns have been subected prior to the winding operations causes them to adhere together and curl and become somewhat matted and entangled, whereupon it is diflicult to withdraw them from the swift without breakage.

By the above-described device the threads are kept at a uniform tension, and it will be seen that when an excessive pull is exerted on the yarn in drawing the same off the swift the hank will tend to contract onto the swift, thus moving the lever-arm slightly, as shown in Fig. 2, the parts resuming their former positions as soon as the excessive strain is removed. The continued reciprocating or jerky movement of the lever 0 causes the threads to be liberated from each other, so that they may be more easily withdrawn from the swift.

I claim as my invention 1. A machine of the character described comprising pirns or bobbins, stationary thread-guides for guiding the yarn thereto, means for rotating said pirns or bobbins, and means acting independently of said rotating means for imparting a longitudinal movement to said pirns or bobbins.

2. A machine of the character described comprising reels or swifts for receiving hanks of yarn, a tension device simultaneously engaging all of the threads of each hank, asliding support for said reels and tension devices, and means whereby said threads are wound on bobbins.

3. A machine of the character described comprising a series of reels or swifts for receiving hanks of yarn, stationary threadguides over which said yarn passes to the pirns or bobbins, spindles adapted to support the pirns or bobbins, means for reciprocating and transmitting rotary motion to said spindles, and means for automatically varying the speed of rotation of said spindles.

4. A machine of the character described comprising a series of reels or swifts for receiving hanks of yarn, spindles adapted to support the pirns or bobbins, stationary threadguides over which said yarn passes to said pirns or bobbins, means for regulating the tension on said yarn, means for reciprocating and transmitting rotary motion to said spindles, and means for effecting variations in the speed of said spindles.

5. A machine of the character described comprising a frame, rails or supports mounted to reciprocate therein, spindles carried by said rail or support, means for rotating said spindles, conical rolls surrounding said spindles, pirns or bobbins loosely mounted on said spindles to have an independent vertical movement, and stationary thread-guides for guiding the yarn to said pirns or bobbins.

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

JOSEPH KING.
