ATTORNEYS Patented Sept. 21, 1948 YARN wmmm Albert E. Winslow, Norwich, Conn., assignor, by

mesne assignments, to Universal Winding Company, Cranston, R. 1., a corporation of Massachusetts Original application September 11, 1943, Serial No. 501,963, now Patent No. 2,385,046, dated September 18,1945. Divided and this application December 9, 1944, Serial No. 567,389

1 This invention relates to a yarn-handling machine, more particularly to the ring twister type and is a division of my copending application Serial No. 501,963, filed September 11, 1943, now Patent No. 2,385,046 dated September 18, 1945.

In machines of this character it is usual to mount the supply package so that its axis extends lengthwise of the machine with opposite ends of a mounting spindle supported. Often clotting of the supply package is cumbersome or awkward.

One of the objects of the invention is to provide a supply package which may be easily mounted upon and withdrawn from the machine even though the supply package is driven. 4

Another object of the invention is to provide an arrangement in which the units each consisting of a supply package and a pair of spindles may be arranged side by side along a length of machine with a common drive for all of the supply packages and a common drive for the spindles. Another object of the invention is to provide an arrangement so that the same frame may be equipped with a plurality of side by side units in back to back relation with a spindle drive for each back to back unit of the assembly.

With these and other objects in view, the invention consists of certain novel feature of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a sectional view through the twister frame between the delivery packages of Fig. 2 showing the yarn as guided from the supply package to the spindle package which is surrounded by the ring and traveler;

Fig. 2 is a fragmental front elevation of a modification largely diagrammatic and illustrating the yarn as led from the supply package to two spindles.

In proceeding with this invention I mount the supply packages on driven spindles each of 3 Claims. (CI. 24.2-35.5)

driven from the belt which travels in a vertical plane and runs lengthwise of the machine to operate all of the spindles or take-up packages throughout the length of the machine. The

spindle is suitably mounted in a swinging bracket which is urged against the belt for driving the same and may be withdrawn from the belt for stopping the spindle, all as more particularly pointed out in my co-pending application Ser. No. 508,817 now Patent No. 2,375,605 dated May 8, 1945, which relates to a stop motion and mechanism for withdrawing the spindle from operating position.

At the upper end of .the supporting stand a shaft isrotatably mounted in a bearing 26 carrying a mandrel at one end for the mounting of a supply package 21 thereon. This shaft also carries a drum 28 with which the back of the V belt 29 may engage to ,drive the same. A V-pulley 30 grooved at 3| fits this belt and serves to move it into engagement with the drum 28 so that the back of the belt may drive the drum.

The yarn on the package 21 is led from this package through the pigtail guide 32 and thence to the bobbin It. By reason of the ring I! and traveler 33 the yarn is caused to balloon and twist with the twist traveling back to the supply package 21 by reason of the substantially straight path of the yarn. The guide 38 only lightly touches it. By the twist traveling back to the supply package all of the endsof the yarn are bound in together making a strong strand and one which cannot pull apart from a point close to the supply package. This is exceedingly important inhandling small diameter yarn, such as glass yarn which may run ninety thousand yards to the pound. Also by delivering directly from the supply package to the take-up package without any intermediate feed rolls less handling of the yarn which extends at right angles to the length of the frame and toward the front of the frame so that the package may be withdrawn from the spindle over the end thereof nearest the operator. 1 drive the spindles by a belt extending lengthwise of the frame.

With reference to the drawings l0 designates generally the structural framework having a supporting stand I I and horizontal angle bars 12 from which brackets l3 extend for guiding the thread guide rod l4 carrying the thread guide l5 at the upper end thereof and which has the ring rail I6 and ring l'l carried thereon for reciprocatis required which also in small brittle yarn as glass serves to abuse the yarn to a substantial I extent. Thus, it is additionally advantageous to cause the yarn to travel from the supply package to the take-up package merely over a minimum number of guiding bars which do not materially deflect it from a straight path.

In some cases in the making of yarn of this character it is advantageous from the standpoint of previous processing to wind more than one varn end on a package in which case a saving is efiected by running two yarn ends or more in parallel relation upon a package. such as a supply .7 3 I package 21. In taking such parallel yarns from the supply package one yarn end will be directed to one spindle while the next yarn end will be directed to the next spindle, and so on if there are more than two. And in Fig. 2 I have illustrated one yarn end 30 as heretofore described as a single, while the parallel yarn 35' is directed over to the package 18' where it travels through the traveler 33" moving about ring rail ll' tobe assembled upon the package I! similarly. In this case the yarn extends-over a guide 3!, and

' through the guide 32' and the twist also runs back to the guide 38' over which the second yarn 35' extends. The twist in the companion yarn ll will as previously described run back to the supply package and will assist in separating the two yarns from each other. It will be understood that the supply packages are driven in each case and the yarn is led with a twist therein running from the take-up package back to the supply package.
