BALL OR COP OF TWINE OR CORD.

SPECIFICATION forming part of Letters Patent 0. 731,888, dated June' 423, 1903. Application tiled November 25, 1902. Serial No. 132,737. (No model.)

.To tu whom may concern:

Be it known that I, JOHN GOOD, a citizen of the United States, and aresident of Far Rockaway, in the county of Queens and State of New York, havev invented a new and useful Ball or Oop of Twine or Cord, of which the followingr is a specification.

The invention relates to what are known as balls or cops in which twine or cord is wound in successive courses of coils which are self-retaining in proper relation -to each other without a tube or any analogous internal retaining device. It is desirable that such a ball or cop, particularly one composed of what is known as binding-twine for use in harvesting-machines, shall contain the greatest practicable length of twine within certain dimensions. It is also desirable that it shall be capable of unwinding in the freest possible manner from its inside without its courses becoming tangled or snarled.

To meet the above requirements, a ball or cop embodyingr my invention consists in its most approved form of a substantially cylindrical body having its ends more or less concave and composed of successive regular helical courses of twine or cord, with an external binding formed by the continuation of the same thread or -cord around the said body in helical courses of such Obliquity to the axis of the cylindrical body as to cross over bot-h ends of said body, and so confine the several helical courses within said body in a direction parallel with the axis thereof.

The invention is illustrated by the accompanying drawings, in which- Figure l represents a perspective View of one of my balls or cops; Fig. 2, an axial section of the same; and Fig. 3, a side view of a portion of the body of the ball or cop, illustrating the winding of said body before the application of the winding courses.

l designates the cylindrical body, the successive helical courses 2 3 4 of which, running in alternately-opposite directions, are simply Wound one upon another," as illustrated in Fig. 3.

5 designates the external binding, formed by winding the helical courses 6 7 8 9, of which it is composed, in the manner illustrated by Fig. l, not only over the circumference of the body, as indicated by 6 8, but also across the ends thereof, as indicated at 7 9. There may be any suitable number of these external courses 6 7 8 9; but there generally need be only a few compared with the number of courses 2 3 4 in the body. Two or three of these external courses may be suliicient, though a larger number may be used, if desirable. Only two are shown. The end of the outer coil 6 9 may be madeA fast in any suitable manner, as by tucking into the ball or cop, as shown at l0 in Fig. 3.

To form this ball or cop, the twine or cord is wound on any suitable spindle under the direction of any suitable guide, by which it may be properly guided during the rotation of the spindle,the latter beingof such slightlytapered form as to allow the finished ball or cop to be drawn olf from it. The ends of the cylindrical body portion l are made slightly concave, as shown at ll, the degree of concavity being determined by end disks on the spindle, which are used during the winding of the body portion and slipped back out of the Way when the external binding is to be applied. The slight concavity at the ends causes the successive layers of thread to tend to compress the inner layers in the longitudinal direction of the axis, and so insures the integrity of the body when the end disks or guides are removed for the purpose of winding the binding course or courses. The central portions of the concave ends of the ball also receive the crossing threads of the external courses, thereby maintaining the end of the completed ball substantially flat and the consequent advantage of a materially greater length of twine or cord within a prescribed space.

In the winding of the external vcourses the tension which is given to the twine or cord tends to compress the ends of the body and to produce the rounding oli? of the ends thereof, as shown in Figs. l and 2.

By the terms twine and cord as hereinabove employed I intend to 'include all fabrics produced by the twisting of fibers-- threads and yarns, for example. l

What I claim isl. A ball or cop consisting of a substantially cylindrical body ofcord or twine having concave ends and an external binding formed by the continuation ofthe body cord or twine the convexity of the ICO me fait. No. 751,888.
