` Claims.

This invention relates to a method and means for packaging cord, yarn and the like, whereby a continuous Strand can be Wound into a number of packages with the strand proceeding from 5 the` iim'shed package to the beginning of another package. More particularly it relates to a method and means for Winding interconnected packages of cordage upon cores from a single strand with means for securing the strand to the core at the beginning of the Winding and also at the linishing of the winding of each package, so as to prevent sloughing of the cord after it has been wound.

Heretofore, in my Patent No. 2,095,765 of October 12, 1937, I have provided means for Winding interconnected packages and for securing the outer and inner layers of the cord to prevent sloughing, which entailed the use of an additional cord, or other fastening element, and also which entailed a great deal of additional time. The present invention has means for securing the cord at the beginning and at the end of the Winding to the core upon which the package of cord is wound Without entailing the use of an additional cord, or other fastening element. When the package has been completed, the strand is looped or otherwise fastened to the core to secure the outer layer of the cordin position. The inner layer of cord is secured to the core by virtue of the pressure of the successive layers which are Wound thereon.

It is, therefore, an object of this invention to provide a method and means for Winding a plurality of balls, from one unsevered length of cord, onto cores, attaching the core to the spindle of a Winder, which spindle is provided with a receptacle to rotate with the spindle; said method comprising the winding of balls, one at a time, on a core, then to prevent sloughing of the outside fore the core with its cord, is removed from the spindle, or after it is removed from the spindle, and transferring the cored ball from the spindle to the receptacle which is located on and revolves With and may be a part of the spindle.

It is preferable to have aprotruding core, with an enlarged end, so that, after the package of cord is wound the outside layer of the ball may be easily looped around the enlarged end of the core and be held securely. It is seen that this provides a very economical method of securing the outer layer of the cord to the core, which does not entail an additional member, and which may be easily released by the user.

55 Some of theA` objects of the invention having layer of the ball, fasten it to the core, either bebeen stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which- Figure 1 is a sectional view through portions of a ball Winder showing the invention applied thereto;

Referring more specifically to the drawings, the numeral I!! denotes the main drive shaft oi a conventional ball Winder Which has a sheave pulley Il mounted thereon which, in turn, has mounted thereon a belt l2, said belt extending up- Wardly and also being mounted on a sheave pulley I3. The sheave pulley I3 is xedly secured onone end of a hollow flyer shaft I4 which shaft is rotatably mounted in longitudinal beam I5 of the ball Winder. On the other end of shaft I4 is xedly secured a ilyer IE, having a counterweight II on one end thereof and a thread guide I8 on the other for guiding the thread or cord to the proper position so that it can be wound upon suitable cores I9 to form packages 20. When rotation is imparted to shaft It] the sheave pulley I3 is likewise caused to rotate which, in turn, rotates the flyer I6 and its associated parts to cause strand 23a to be drawn from a cone 2| through the interior of shaft Ill and onto package 2l), which is disposed on the upper end of a spindle 2li. The spindle 2li has a lower restricted portion 24a which is rotatably mounted in longitudinal beams 25 and 26.

A worm gear 2l is xedly secured on the restricted portion 2da and is adapted to mesh with a worm 28 flxedly secured on a shaft 29. The spindle 2li is so geared with respect to shaft 29 that one complete revolution is made each time a layer of cord or yarn is wound around the package 2), that is to say, when one revolution of the spindle 2d is made, a plurality of revolutions are made by flyer IG. Since the flyer rotates in one direction at a rapid speed and the spindle rotates in the opposite direction at a slow speed, a transverse wind is produced.

It should be noted that the upper end of the core or spool I9 has a flanged bell-shaped rim Ia. After the package of cord 2) has been wound, the operator grasps the cord close up to the outer` layer (Figure 5) and forms a suitable loop 32 therein and then places this loop over the projecting end of core I9 and adjacent the flanged rim Isa after which the loop is tightened to the position shown in Figure 6. After this operation has been performed, the cord is not severed but immediately the package is .transferred from the spindle to a pin 3l which pin is secured in a suitable plate or table 38 disposed on spindle shaft 2d. A plurality of pins 3l are disposed in the plate in order that a plurality of finished balls or packages of cord 2D may be accommodated. In the present instance, space has been provided whereby a dozen balls may be accommodated bey fore severing the strand 2da.

By referring to Figures l, 2 and 5 it will be noted that a leaf spring clamp 39 is secured to the side of spindle shaft 2d in order that the intermediate portions 29a of the cord between the ball, which is disposed on pin 31, and the ball which is being wound on the spindle might be clamped to the spindle and heid securely while the next ball is being wound on the spindle. Of course, when a ball hasbeen wound and the loop 32 tied, the intermediate length 2da of the twine between the balls which is under the clip is removed therefrom and then the finished ball 2i) is placed on a pin. After this has been done a portion oi the same strand disposed on the upper side of the ball is placed under the clamp 39 and then the process of Winding another ball is repeated.

In Figures l to "I, inclusive, I have shown a single loop for securing the outer layer of` cordage to the core I 9, but it is to be understood that any desired type of loop may be utilized without departing from the spirit of the invention. In any event, it is seen that the inner layer of cord is secured to the core I9 by the pressure' of the succeeding layers Ywhich are wound thereon, and

the outer layer o-f the cord is secured to the core by means of a suitable loop which is wrapped around the enlarged end of the core.

Figure 8 shows a tube 40 which contains a plurality of packages or balls 20 therein wound in series from one continuous strand. It is evident that when a retailer desires to sell a continuous cord, which has no knots therein, almost any continuous length, within certain limits, can be .obtained without the necessity of carrying a number of different length balls of yarn or cord in stock. For example, by using this method, a dozen balls with fty feet in each ball can be packed in one container, and if the retailer desires, he can sell any number of yards in one continuous length varying in units from fty feet to `siX hundred feet by merely severing the cord disposed between two adjacent fty foot balls at the desired point.

Figures 9 and 10 show a package of cord after it has been wound upon a slightly diierent form of core and having the outer layer of the cord secured to the core by a double loop instead of a single loop as shown in the preceding figures. In this form a cylindrical core 4I is employed, which has the same outside diameter throughout its length. One end of the core projects a substantial distance from the package 2i). After the package has been completely wound, the operator grasps the unsevered cord adjacent the outer layer and forms a double loop 42 therein (Figure l). This loop is placed around the projecting end of the core, and then tightened to 'the position shown in Figure 10.

Figures 1l, 12 and 13 show still another modified form of the invention. In this form the package of cordage, yarn or the like 23 is wound around a core d which core has integral with one end thereof, a restricted projection 45a, said projection being adapted to fit in a suitable cavity in the upper end of a spindle 4I. This spindle has a spring clip 48 secured thereto for clamping the strand 2da intermediate the balls of twine. 'Ihe lower end of the spindle ll'l is secured to a U-shaped bar [i9 and this bar has its end secured to the-upper portion of receptacle 50. The receptacle 5I] may be of any desired material or shape and is used for placing the wound balls therein after being removed from the upper end of the spindle il?. In other words, the receptacle 50 answers substantially the same purpose as table 38 and its associated pins 31; however, it should be noted that it is necessary to use a receptacle of this type, especially when a solid core 45 is used instead of a tubular member such as indicated by reference characters I9 and Isa in the preceding iigures of the drawings.

The Alower portion of the receptacle 53 kis secured to a spindle 5l by any suitable means such as set screw 52. The spindle 5I is merely a continuation of the spindle 41 and it has worm gear 2l' secured' thereon by means of set screw 21a.

After the package 2i] has been wound properly upon core t5, the core is removed from the upper end of the spindle and the unsevered trailing end of cordage 29a is secured to the end of the core by any suitable fastening means such as looping, tieing, and the like. In Figure 13 the loose end 20a is secured by means of a single loop which is fastened over the restricted portion 45a. In Figure 14, the loose end 20a is secured on the restricted end portion 45a by means of an addtional cord 5d which is ltied around the restricted portion 45a and the loose end 20a. In Figure 15,

a core is shown having restricted portions 55a integral therewith and also having a cavity 56 in one end thereof. Whena core of this type is used, the loose unsevered end 20a is secured to the core by means of inserting a suitable plug 51 in the cavity on topof a doubled portion of the unsevered end.

While I have'shown several types of fastening means for securing the outer layer to the core, I desire it to be understood that these means are merely illustrative of the fact that any desired type of fastening means may be employed to prevent the outer layer from sloughing.

I also desire it to be understood that although I have shown two different forms of receptacles for holding wound balls, it is to be understood that any suitable receptacle may be provided on the spindle for holding the balls while additional balls are being wound.

In the drawings and specication there has been set forth a preferred embodiment of the invention, and although specic terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the appended claims.

I claim:

1. That method of winding cord into a plurality of balls onto tubes from one unsevered length of cord employing a winding spindle provided with a table to rotate with the spindle, which comprises winding a ball on a tube on the spindle, then securing the last round of cord on the wound ball against sloughing by looping the cord around the end of the tube, then transferring the wound ball with its tube, from the spindle onto the table and winding succeeding balls in the same manner without severing the cord.A

2. That method of winding cord into a plurality of connected balls, on tubes disposed on a winding spindle provided with a table adapted to rotate with the spindle, Which comprises winding a ball on a tube on the spindle, looping the last round of cord around the end of the tube, removing the ball when wound with its tube from the spindle and mounting the completed ball on the table and `winding additional balls in the manner described, whereby a continuous length of cord can be wound into a plurality of interconnected balls.
