Application June 1'7, 1939, Serial No. 279,640 2 Claims. (Cl. 242--18)' This invention relates to winding devices used in textile and other industries where filament or strand material, such as thread, yarn, cord and the like, is wound on suitable instrumentalities,

5 such as bobbins, spools, spindles and the like,

from quantities or skeins of the indicated material.

The principal object, of the invention is the provision of a winding device or unit of the 10 character mentioned, which is adapted to hold the material stationary in the form of a coil,

and unwind the same therefrom and synchronously wind it on the desired instrumentality.

Some of the features and advantages of the 15 invention areas follows: It is possible to operate at high speed without increasing the tension of the strand. Thewinding speed of the strand does not increase the tension, therefore,

the tension may be easily controlled and regu-. lated. A skein in the form of a coil may be held to bobbin faster than at present, while decreas ing the amount of Waste material, lessening 3o breakage, per skein, obtaining uniformity of thread or yarn, eliminating soft bobbins, and consequently reducing operation and labor costs. In the drawings to which reference is made in the following specification- 35 Fig. 1 is a fragmentary side view partly in section of a machine embodying the winding'device of the present invention;

Fig. 2 is a front view partly in section; and Fig. 3 is a side view of the unwinder detached. Referring now more particularly to the drawings, it will be apparent that there is illustrated parts of a conventional machine adapted to wind yarn on a bobbin from a skein and the same being selected to show the device of the 5 present invention applied thereto. The machine includes a drive shaft l0 and stationary horizontal rails II and 12. A plate I3 is fixed on the rail H. This plate has spaced apertured lugs l4 integral therewith and brackets 15 are respec- 50 tively pivotally connected with said lugs 14, as at I6, so that they are free to pivot up and down. The brackets 15 carry a bobbin H, the trunnions 18 of the latter being respectively received in notches I9 or 20 in the brackets. Therefore, the 5 bobbin may move up and out as the yarn is wound onitincreasingthe diameter. A two-part shaft 2? is supported by bearings carried by the brackets l5. Abobbin driving roll 22 is fast on the shaft parts 2| between the brackets [5. The roll 22 has a hub 23 and a V groove pulley 24 in- 5 tegral therewith or secured thereto on one end.

A grooved pulley 25 is fast-on the drive shaft if). .'A rubber ring 26 is disposed in the groove in the pulley 25 and is cemented to the latter. This.

ring 26 constitutes a friction means which contacts the walls of the V groove in the pulleyilt to in'lpart rotary motion to the pulley 26 in response to the rotation of the pulley. This will cause the rotation of the roll 22. The cylindrical surface has applied thereto cork or other friction material to provide a cylindrical friction surface to contactually engage the cylindrical surface of the bobbin H or the windings of yarn wound thereon, in order to rotate the bobbin in the yarn winding operation. I

A traversing and tensioning means 21 serves to guide the yarn under tension to the bobbin.

A counterbalanced stop motion 28 is operatively carriedby a bracket 29 extending forward-' i ly and downwardly from the plate l3. This stop motion 28 includes a porcelain eye fill through which the yarn passes to the means 21; If the yarn breaks the stop motion 28.cooperates With the hub 23 to lift the pulley 24' out of frictional engagement with the ring 26, thereby stopping 30 I the rotation of the bobbin I'i.

The

means

21 and 28 are conventional and no claim is made herein to the specific features thereof.

In accordance with the invention, use is made of a suitable holder, for the material, such as the yarn mentioned hereinabove, by way of example. The holder may advantageously consist of a circumferentially adjustable swift 3| of open sided type, as shown most clearly in Fig. 2. For

this purpose a bracket 32 is secured to the rail 12 and rises therefrom. A sleeve 33 has one end secured to the bracket 32 so. as to project horizontally therefrom. The hub of the swift 3i has a frictional fit on the sleeve 33 and, therefore, holds the swift 3| stationary during normal winding operation, but it may be manually rotated to permitmounting of skeins and tying of yarn ends. Roller bearings 34 are positioned respectively inthe opposite ends of the sleeve 33 and 1 these bearings support a shaft 35.

A grooved pulley 36 is fast on one end of the shaft 35 and a grooved pulley 31 is fast on the shaft 2|. A rubher belt 38 encircles the

pulleys

36 and 31. Rotary I motion is therefore transmitted to the shaft 35 from the shaft Ml through the intervention of the pulley 25, pulley 24, shaft 21, pulley 31,- belt 38 and pulley 36. The belt being of rubber and therefore elastic allows the stop motion 28 to function to stop the rotation of the bobbin.

In accordance with another feature of the invention a traveler is provided to unwind the yarn from a skein held stationary on the swift 31. This traveler rotates with the shaft 35 as driven by the pulleys 3G and 31 and the belt 38. The traveler consists of a disk 39, radial member it, take-up eye M and central let-ofi eye 42. The disk 39 is secured to the end of the shaft 35 remote from the pulley 36. The member 40 consists of a wire which is flattened near its inner end as at 83 and this flattened portion has holes therein to accommodate suitable fastening elements 44 which securely fasten the member 40 to the disk 3S9. The take-up eye 4| is formed on the outer end of the member 40 from the material of the wire stock and is left open so that the yarn may be engaged therein. The let-off eye $2 is also formed on the inner end of the member 40 from the material of the wire stock and is also left open for engaging the yarn therein. The let-on eye 42 is disposed concentric to the axis of the shaft 35. The member 49 is disposed radially at the open side of the swift 3| and is sufiiciently long to bring the take-up eye 4! beyond the skein carriers of the swift.

A skein of yarn or any other filament or strand material is held stationary in a coil by the swift 3i and the yarn is passed through the eye H, thence is brought inwardly toward and through the eye 32, thence upwardly through the eye 39, beyond which it is engaged by the tensio-ning and traversing means 27 and finally fastened to the bobbin on which the yarn is wound. The yarn is designated 45.

The skein (not shown) remains stationary on the swift 3i and the yarn is unwound by the revolving power driven traveler that takes the yarn from the skein and carries it out through; the central eye 32 up to the bobbin I? on which itis wound, permitting a comparatively high operating speed because the tension remains uniform at any speed. The yarn is thus unwound or paid out freely from the source of supplyand wound on the bobbin in-synchronism. It is, therefore,

possible to attain all of the advantages hereinbefore mentioned. I

In many instances the use of the

pulleys

24 and 36, as well as belt 38, is desirable. In some cases, however, these pulleys and belt 38 may be eliminated and the yarn fed directly to the winding spool from the arm 40. When the belt 38 and associated. parts are eliminated, a pull of the yarn on the arm M] will cause the same to rotate and thereby feed the yarn properly to the winding spool.

It is to be understood that the invention is not restricted to the precise embodiment thereof as illustrated and described, but that details of construction may be modified and rearranged Without departing from the spirit of the invention as defined in the claims.
