Patented Oct. 1, 1929 UNITED STATES PATENT OFFICE CHARLES H. COLLINS, DECEASED, LATE OF AMSTERDAM, NEW YORK, BY MARY COL- LINS OF CRAI'TESVILL'E, NEW YORK, EXECUTRIX MACHINE FOR WINDING TUBE-PRANIE SPOOLS Refile for abandoned application Serial No. 83,787, filed January 26, 1926.

December 22, 1927,

This invention relates to devices for winding a multiple number of yarns upon a single spool, particularly tuft yarn spools used on the tube frame of Axminster looms.

The object. of this invention is to provide a winding mechanism which will so compact the yarns as they are laid upon the spools that an appreciably greater length of yarn may be placed thereon without increase in the maximum diameter of the filled spool;

thereby making possible a considerable increase in the product from a loom, equipped with tuft yarn spools which have been wound by this improved device before it will become necessary to replace or rewind the spools.

The object of this invention is accomplished by means of an improved spool winding mechanism which is very similar to that disclosed by the United States Patent No. 1,185,633, granted June 6, 1916, but differs therefrom in certain vital particulars which will be hereinafter described and claimed. This further improved spool winding device is illustrated in the accompanying drawings, in which:

Fig. 1 is a side elevati-on, parts omitted, of this further improved spool winding device with a partly filled overwound spool therein.

Fig. 2 is a front. elevation of the winding rolls and their actuating inechanism, with a partly filled spool in place therebetween, parts broken away.

F ig. 3 is a. cross section through the winding rolls, as along the line in Fig. 2, and illust-rates the manner in which an underwound spool is filled by the same device.

The same reference characters refer to the same parts throughout the several views.

Referring to the drawings: F represents the frame of the device, or a portion thereof, in which there is journalled a spaced pair of rolls R1 and R2, which are of the same diameter and are driven at the same speed by any suitable means, here shown as the spur gears 1', r, attached to the sha-fts thereof, and both of which mesh with a driving spur gear clg, secured on the shaft 35, and which is driven as by a Cha-in 37, and sprocket 36, from any suitable and available source of power (not This application filed seria no. 241,875.

shown) so controlled that the direction of rotation may be reversed at will.

To the shaft 35 there is j-oined, by means of. a suitable fieXible coupling or universal Joint 311, an extension 33, which in turn is connected to a second universal joint 32, secured to or forming a part of the gear sleeve 31, pivoted, and limitedly shiftable longitudinally on a stud 30. The connection between the extension 33, and one of the universal joints 34 or 32, is such that a limited telescoping between the extension and the coupling is possible. See telescopic joint with pin and slot connection 33x, F igure 2.

The gears 28, and 29, on the sleeve 31, are of different diameters, and the gears 211 and 25, on the sleeve 26 are also of different 'diameters, the relative diameters thereof being such that when the gears 24: and 28 are in mesh the peripheral speed of the roll S, driven by the sproclret 23 on the sleeve 26, through the Chain 22, and sprocket 21, will be slightly greater than that of the rolls R1 and R2, while the peripheral speed of the roll S when the gears 25 and 29 are in mesh will be slightly less than that of the rolls R1 and R2.

The downwardly projecting ends of the member u, are hinged at h? and H2, to parts 71.3 and 72/* respectively which are slidable vertically in the end portions of the frame F, and the studs which carry the sleeves 26 and 31 are mounted in or are secured on the same vertically slidable piece so that as the spool lills they and the roll S Will move upward as a unit.

Suitable means, as for instance, the lever 15 pivoted at 16, and the handle 17, are provided whereby the sleeve 31, may be shifted at will so as to change the speed of the roll S. Vhile I now prefer to provide for the change in the direction of rotation of the rolls at the source of power, or between such source and the winding machine, I may include a change mechanisin in the machine itself.

In a device illustrated by the prior patent, above identified, tension is applied to the yarns as they are wound upon the spools, by reason of their being drawn between measuring rolls which are driven thereby and so cause tension thereon.

In this improved apparatus a substantially like result is attained without this external tensioning means. In this present device, the desire'd tension on the yarns is secured by having the peripheral speed of the roll S, such that it will aot as a brake to retard the free passage of the yarns thereby as the spool is rotated, by causing a slip to occur between the yarns and that roll.

In order to properly wind both overwound and underwound spools in the same device, there has been provided means whereby the speed of the roll S may be changed at will, for when an overwound spool is to be filled it is necessary that it have a slightly lesser peripheral s eed, and when an underwound spool a sllightly greater peripheral speed than that of the rolls R1 and w R2, in order that the proper amount of slip to produce the desired tension, may occur and that in the right 'direction 'It is, of course, obvious that if but one type of wound spool is desired the means for changing the speed of the roll S, may be omitted, and without departing from the spirit of this invention.

This application is a refile for abandoned application Serial No. 88,787, filed Jan. 26,l

`What is claimed is:

1. In a device for winding yarns onto a tube frame spool: a spaced fiXedly supported pair of rolls adapted to support a spool placed thereon and to contact with the yarns being wound thereon; means for causing rotation of said rolls at the same peripheral speed; a

vyieldingly supported roll adapted to lie in contact with the yarns being wound on said spool on said pair of rolls; means whereby either one of two pheripheral speeds, one greater than, the otherA less than the peri pheral speed of said pair of rolls, will be imparted to said yieldingly supported roll when said pair of rolls are caused to rotate.

2. A process for winding yarns onto a tube frame spool, and consisting in supporting and 'driving the spool between a multiple number of driven rolls which contact with Jthe surface of the layer of yarns as they are laid upon the spool, one of said rolls adapted to yield as the spool fills, and one of them having a peripheral speed dififerent from that of the others whereby braking tension is applied to the yarns as they pass thereunder.

In testimony whereof I have afiixed my signature.
