To all whom it may concern:

Be it known that I, HERBERT W. OWEN, a citizen of the United States, and a resident of Dover, in the county of Strafl'ord and State of New Hampshire, have invented certain new and useful Improvements in Spinning or Winding Machines, of which the following is a specification.

This invention relates to machines for winding yarn or thread upon a rotating bobbin wherein means are employed for traversing the yarn or thread guide so as to build up the bobbin in the desired form. Such mechanisms usually constitute what are termed ring spinning frames and in operation form what is known in the art as warp or filling wound bobbins.

As well understood by those skilled in the art, the strain or draft on the yarn is dependent upon the weight -of the traveler and with the same traveler, such strain or draft varies accordin to the diameter of the part of the bobbin being wound, or, in other words, the angle the yarn or thread makes with respect to the center of the spindle or bobbin. It is least when the yarn or thread is being wound at the largest part of the warp or filling wind, as at the base portion of the conical end; and is greatest when the yarn or thread is being wound at the smallest part of the conical end, which is usually the bare bobbin or spindle. For this reason it has been a common practice to change travelers for varying sizes and quality of yarn or thread. As the weight of the traveler governs to a large extent the amount of yarn or thread that can be placed upon the bobbin, it follows that the heavier the traveler, the greater the efliciency of the machine. Breakage of yarn or thread occurs most frequently when the strain or draft upon the yarn is greatest, that is when the yarn or thread is being Wound at the smallest part of the conical end of the bobbin, consequently the strain or draft on the yarn at this point determines the permissible weight of the traveler 'in either the warp or filling wind.

In the formation of filling wound bobbins by spinning frames of usual construction and operation. the layers of yarn are wound in conical relation, and both the base and tip or end of the wound mass have been of substantially the same conical form. It is desirable, of course, to increase the amount of yarn in such filling wound bobbin, and in case of bobbins for use in some types of looms, such for instance as filling replenishing looms, bunches of yarn have been formed near the base of the bobbin, but the formavide a machine for spinning or winding with means whereby the strain upon the yarn is relieved thereby permitting the use of a heavier traveler, and wherein, when producing filling wound bobbins, a simple and efficient means is provided for the formation of a bunch and the wound bobbin made to contain an increased quantity of yarn.

These and other features of the invention will best be made clear from the following description and accompanying drawings of certain forms or embodiments of the invention, it being understood that the invention is not restricted thereto, but may be embodied in various other forms or constructions within the true scope of the invention. as defined by the claims.

Of the accompanying drawings,-Figure 1 is a front elevation of so much of a spinning machine as is necessary to illustrate my invention in one of its embodiments. Fig. 2 is a detail plan view of a bobbin, ring and traveler to illustrate the direction of the yarn when being wound on the bare bobbin. Fig. 3 is a detail elevation of the builder motion looking from the right of Fig. 1. Figs. 4, 5' and 6 are detail elevations to illustrate the building up operation. Figs. 7 and 8 are views similar to Fig. l, illustrating a modification hereinafter described, said Fi s, 7 and 8 showing the parts in different positions. Fig. 9 is a detail view similar to a portion of Fig. 8, but illustratin a further modification.

%imilar reference characters indicate the same or similar parts in all of th views.

Referring first to Figs. 1 and 2, the spindle rail 15 supports the spindles in the usual manner, only one of such s indies being shown as at 16. The ring rail 17 carrying rings as at 18 for the travelers, such as shown at 19 is su ported upon lifter rods, one of which is sliown at 20. The rocker 21 having a weight 22 to elevate the ring rail has a rocker arm 23 from' which a link 24 extends to anpther rocker arm for another lifter rod. The rocker arm is provided with the usual segment 25 having a bolt 26 to which is connected one end of the chain 27 baid chain 27 in the particular structure shown, is-in three parts or sections, two sections of which are connected by a closed spring 28, the third section being connected to the secondsection byia swivel.29. The .chain passesover a sheave 30, mounted in a yoke 31, the latter being mounted in bearings 32, carried by a bracket 33, supported by a fixed part of the frame; The extreme end of the chain 27 is connected at 34 to the lever 35 which is pivoted at 3'6 to the builder arm 37, the latter having a weight 38 and carrying a roll 39 which is actuated by the traverse cam 40.- The lever 35 is provided with a curved bearing surface 41 for the roll 42 which is carried by the slide 43 having teeth 44: engaged by the worm 45 on shaft 46. Said shaft has a pick wheel 47 which is engaged by the actuating pawl 48. -This general character of builder motion is well known so its operation need not be described herein r 1 One oftbe important features of the pres? ent invention is the fact that the connection between the builder motion and the rocker arm is elastic, such elasticity serving to relieve the strain or draft on the yarn, as will presently appear.

As hereinbcfore noted, it is desirable to use a heavy traveler, because thereby a more compact and homogeneous wound bobbin can be produced. The weight of the traveler,

however, must depend upon the capacity of the yarn or thread to resist rupture when subjected to its maximum strain or draft which occurs at the conical end of the windings or when the yarn or thread leads nearest to the axis of the bobbin or spindle. At or about'this point in the conical wind the ring-rail changes direction of movement, and, it may be, the rate of travel'of the yarn or thread is changed owing to the change in diameter of the windings themselves when the rotation of the bobbin remains uniform. The present invention contemplates means for relieving any sudden'change or increase in the strain or draft upon the yarn at this and other time by the provision of the elastic section in-the connection between the buildermotion and the rocker arm. This feature of the invention, in the illustrated form thereof, is secured by a spring 28 the coils of which are preferably closed. upon each otherin normal operation of the machine, but capable of separation under the action of sudden strain, thereby enabling a heavier traveler to be employed without danger (if-rupturing or breaking the yarn or tiii thread. This structure results in making the ring-lifting mechanism responsive to the 1 mine-lov and sensitive in relievinx the yarn or thread from sudden change in strain or draft when the latter is at or about its maximum. The

particular reason for employing a spring the COIlS of which are normally closed, is to provide a limit beyond which the recoil or shortening-up effect of the connection between the builder, motion and rocker arm cannot act, but as obvious to those skilled in the art, this effect'may be otherwise accomplished.

Figs. 4, 5, and 6 illustrate the bobbin a with the cone base Z) which gives to the bobbin base a more full and rounded form than is presented at the tip. or top of the filling Wound bobbin. I

I In the operation of the present machine, the cone base portion 6 is first wound by traversing the ring-rail to a less extent than i will more fully appear.

In order that the bunch may be shortened as indicated in Fig. 6, and still contain as much yarn as usual, resulting in providlng a better form of bunch, ll provide means for.

reducing the traverse, the machine being operated at usual speed during the building of the bunch.

, Referring to Fig. 9, connections between the builder motion and the rocker arm are dili'erent from the direct chain shown in Fig. 1, although also including a spring. Tn said Fig. 9, a short length of chain 51 is connectedto the rocker arm bolt 26, the other end of the chain being connected to a yoke 52 in which is mounted a pulley 53. A. chain 54 is connected at one end to the swivel 29 and passes around said pulley 53 and at the other end is connected to one end of a closed coil spring 55, the other end of said spring being connected as at 56 to a link of the chain 54. This chain 5% and its spring 55 constitute a loop within which is mounted the pulley 53. 6G to the-chained adjacent the spring 55 1s a chain 65, the other end of which is ad- Connected at while the rocker arm is to the left of the position shown in Fig. 9) are by this form of the invention reduced one half because the taut chain 65 holds the point where it is attached to the chain 5- stationary, and the spring 55 expands and contracts as the builder motion chain section 27 alternately pulls and gives up. The loop around pulley 53 of course thus lengthens and contracts and causes the pulley 53 and chain section 51 to move one half the distance that is imparted to the chain section 27 by therbuilder motion during the building of the bunch. Consequently the traverses of the ring rail are one half as much as usually imparted, and the result is that short, close-built bunches are formed, as indicated at b in Fig. 6, in comparison with Figs. 4 and 5. As the builder chain lets out, the change is gradual to a full-length traverse. In other words, during the building of the bunch or initial portion at the base of the bobbin, the ring-rail performs its traverse adjacent the bobbin base, at which time the chain 65 acts through the spring to move the run'of chain loop about pulley 53 as the chain section 27 through the builder motion moves to the left from the position indicated by Fig. 9, for instance, and back again, thus at such time the pulley 53 acts as a movable pulley, decreasing the traverse ofthe rail to onehalf of what it would be were the chain 65 always slack. As the bunch or initial base portion of the bobbin is formed, the successive traverses of the ring-rail gradually become greater, because the builder motion causes gradually less and less drop to the ring-rail, so that chain 65 acts less and less upon the loop about pulley 53, with the result that when the bunch or initial portion of the bobbin has been completed. the builder motion will not cause the rocker arm .23 to move to the left su'tficiently to. permit the chain 65 to act upon the loop and the normal traverse of the ring-rail will be reached and continued to the top of the bobbin.

Instead of employing a straight chain section 65, I may provide a chain 58 (Figs.

.7 and 8) connected as by a link 57 to the end of looped chain 54 where the latter is connected to the spring-55, said chain 58 being in the form of a loop in which is a pulley 59. The other end of the chain 58 is connected as at 60 to the rocker arm 23. it

is to be understood of course that the movement of arm 23 to the left for each traverse stops at a pointin advance of the last preceding stop, in order to cause the successive traverses of the ring rail tobe in higher planes. During the highest traverses the looped chain 58 is ineffective and is slack. But during the lower traverses, the looped chain 58 performs the same function as the chain in Fig. 9, but acts quicker owing to the looping of the chain around the pulley 59. To avoid overlaying the first traverses of the bunch resulting from the use of the construction shown in Figs. 7, 8 and 9, I provide means for letting out the builder chain faster at the beginning of the spinning operation.

Referring to Fig. 3, it will be seen that I provide the lever 35 with a steep incline from the point 00 to the point 1 over which the roll 42 rides during the building of the bunch. l/Vhile the slide 43 is shifting to carry the roll 42 beyond the point 5 the traverses above the bunch are being effected. As the roll travels from point a: to point y, the builder chain will be let out much more rapidly than after passing beyond point y as will be evident from Fig. 3.

The structures illustrated in Figs. 7, 8 and 9 provide for increased efliciency by employing a pulley leverage that will provide a sensltive structure to bring less strain yarn that can be wound thereon, yet it has come into almost universal use for several reasons such as because the spinning breaks are reduced, the yarn is more readily removed from the bobbin, and because a more symmetrically perfect bobbin is formed. My present invention enables me by the simple addition of a hold-back connection in the manner shown, to more easily form the bunch or cone base of yarn wound upon a straight bobbin. Moreover, this formation of the bobbin is ideal for looms having the well-known feeler attachment, because the waste of yarn is reduced to a minimum.

As hereinbefore mentioned, my improvements are not necessarily limited to the specific type of winding machines, known as spinning frames, as it is obvious that a machine similar to the one illustrated, but not providing for imparting a twist to the yarn or thread would be properly called a winding machine.
