WILLIAM SCHOLES, OF PHILADELPHIA, PENNSYLVANIA.

PROCESS FOR TWISTING- AND WINDING TWINES.

Application filed November 8, 1916.

To all whom it may concern.

Be it known that I, l/VILLIAM SoHoLns, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Processes for Twisting and /Vinding Twines, whereof the following is a specification, reference being had to the accompanying drawings.

This application discloses the same subject matter as my companion application, Serial No. 130,129, filed Nov. 8, 1916, which appli cation claims the apparatus for carrying out the process claimed herein.

The invention is more particularly directed to a process for first producing twine by twisting and attenuating paper in ribbon form, and thereafter winding the same into cops, for use in weaving textile fabrics.

This I accomplish by bodily rotating a roll of the material while unwinding the same, thereby producing a twist which is subsequently crushed and attenuated by a series of eyelets, of successively decreasing diameters, interposed in the path of the material, while the latter is directed to a rotating spindle upon which the cop is formed.

By my improvement, I have provided a novel and simplified method of effecting the above with an accompanying saving of time and a corresponding decrease in the cost of manufacture.

The process of twisting and winding according to my invention, may be conveniently practised upon a machine constructed as shown in the accompanying drawings, in which,

Figure I, is a transverse sectional and Fig. II, a detail of the same on an enlarged scale.

The paper which is to be subsequently twisted and wound, is out from a comparatively long roll, into a number of narrow sections which are subjected to a certain degree of moisture, this being essential in facilitating the formation of a permanent twist by the machine. One of these sections, indicated at 1, in Fig. I, is laid fiat upon a rotating table 2, and unwound preferably from the center, as shown. Table 2, is rotated in a direction corresponding to that of the natural curl of the paper occasioned through its initial winding into roll form.

Specification of Letters Patent.

Patented Dec. 28, 1920.

Serial No. 130,130.

The paper ribbon R, is drawn from the roll 1, by being wound upon a spindle 3, under the guidance of the rollers 5, and 6, mounted on the supporting stem 7. By the simultaneous rotation of the table and. spindle, the paper ribbon is given the proper twist as it is wound into the cop form represented at 8.

Interposed in the path of the ribbon between the supply source and the spindle, are a series of crushing and attenuating eyelets 9,10, and 11, which are mounted in suitable supporting arms 12, adjustably clamped upon the stem 7, already referred to. As best shown in Fig. II, the apertures of these eyelets areof successively decreased diameters, so that the already twisted yarn is gradually crushed and attenuated before being wound upon the spindle.

The rotating table 2, for the roll of mate rial is purposely located at a point quite remote from the guide roll 5, so; that an automatic compensation or equalization of twist may take place among the convolutions in the very considerable free, wholly unconstrained length of ribbon and between the successive convolutions of the material, and the pitch thus be rendered uniform and an even twist obtained in the twine. Rotation of the table is eifected through frictional contact with a disk 13, which is continu-' ously driven by means of a belt from the main shaft.

The spindle 8, is formed with a squared portion 15, which is capable of sliding longitudinally in a driving sleeve 16, journaled in bearings 17, and 18, projecting from the frame 19, of the machine. Sleeve 16, is provided with tight and loose pulleys 20, and 21, respectively, and is driven from the main shaft 23, by a belt 22.

A winding cone 25, cooperates with the spindle in such a manner that the latter is gradually shifted to the right as the cop is building. This winding cone is mounted upon an arm 26, loosely fulcrumed about a fixed rod 27, and is maintained in operative position by means of a spring 28. The arm may, however, be readily manually retracted in opposition to the pull of spring 28, to permit the removal of the finished cop from the spindle.

An oscillating feed arm 30, associated with the winding cone and spindle, vibrates through an amplitude corresponding to the belt 35, from the main shaft.

As the cop gradually builds upon the spindle, with an attendant shifting of the latter as already described, a collar 36, on the said spindle finally engages a pivoted trip 37, and raises the same from the path of a collar 38, fixed upon the belt shifter rod 39, and allows the latter to be shifted under the force of an encircling compression spring 4:0, to the extent allowed by the buffer collar d1. This results in shifting the belt 22, from the tight pulley 20, to the loose pulley 21, thereby rendering the spindle idle upon the completion of a cop of the desired length.

At this time, it is also necessary that the table 2, cease rotation and accordingly the following mechanism has been provided: Pivoted adjacent the table 2, upon a fixed rod 50, is a brake arm 51, in the form of a bell crank lever, which, when released is adapted to engage with the periphery of the said table under the pull of the coiled spring 52. Lever 51, is coupled by means of link 53, with the arm 55, of a detention finger 56, which is fulcrumed about a fixed rod 57, and normally engaged by a pin 58, projecting laterally from the shifter rod 39. As this rod is automatically tripped to stop the rotation of the spindle, the brake 51, will likewise be automatically applied to the table 33, whereupon, the operator may rewhich my process may be practised, and admits of various modifications and arrangements without altering the principles through which the desired result is obtained.

WVhile I have used the word paper in the following claim, I, of course do not wish to limit the practice of my process to this material alone, since it may be readily used in similar manner in the treatment of other materials of like nature.

Having thus described my invention, I claim:

process of twisting ribbon into twine, consisting in drawing the ribbon from a roll through a series of stationary crushing eyelets of successively decreasing diameters with a considerable free, wholly unconstrained length of ribbon between roll and eyelets, so as to permit thorough equalization of twist among the convolutions and render the pitch of the twine uniform, simultaneously rotating the roll in the direc tion of the natural twist in the ribbon as drawn from the roll.

In testimony whereof I have hereunto signed my name at Philadelphia, Pennsylvania, this fourth day of November, 1916.

WILLIAM SGHOLES.
