motion to the beam of the machine during the winding of the threads thereon so that the threads willlay on toprof each other at an angle instead or parallel to each other, to the end that warp streaks will be eliminated.l

As is well known in weaving' the present tendency is for the warp sections to leave streaks in the cloth due to notvbeing evenly distributed on the beam. In accordance with the present invention an even distribution of the warp sections and the winding thereof on the beam will be accomplished so that the streaking above referred to will be lessened if not entirely obviated.

A further obj ect-of the invention is to eliminate the present practice ofv rolling stiff cardboard every fewrevolutio-ns of the beam in order to keepthe warp ends straight and allow a uniform tension on all ends in weaving as is now required in the beaming of finer yarn. The objection to the use of such cardboard is that the same increases the diameter of the warp beam for a given length warp to such a proportion that dithculty is encountered in the 'use of the warp in a loom.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is an enlarged sectional View illustrating the application of the attachment to the warp beaming machine.

Figure 2 is a View partly in section and partly in elevation showing the manner in which the thrust wheel or gear is mounted in accordance with the present invention.

Figure 3 is an elevational View of a cam disk and a supporting plate therefor.

Figure 4 is a plan view of the body of wheel.

Figure 5 is a fragmentary sectional view through the rim of the thrust wheel, a retaining rivet being also shown separate from the wheel.

Figure 6 is an elevational view of a portion of the rim of the thrust wheel.

Figure 7 is an elevational view of a frustreconical roller, pin and bearing sleeve therefor,

and

Figure 8 is a perspective View of a bushing to be hereinafter more fully referred to.

Referring to the drawings by reference numerals it will be seen that I I indicates generally the thrust a portion of the warp beaming machine while the reference numeral l2 indicates a portion of the beam core. f

In accordance with the present invention the beam :core I2 is mounted for free longitudinal "-5 play in its bearings and at one end is provided with a reduced portion ma.

The attachment is indicated generally by the reference numeral I3 and in the present instance comprises a'plate I that is secured to the frame 10 of the warp beaming machine through the inedium of boltsor other iastening elements i5. The plate is provided with upper and lower ilanges I6,'and confronting the plate it is a second plate v I'Irwhich is also provided with upper and lower l5 flanges I8 which are secured to the iianges. It of the plate- I i by a bolt and nut means IS.

Intermediate their ends the plates It, l'i are provided with bearings 2&3, 2 I. These bearings accommodate the end 52a of the beam core as shown 20 in Figure l. On the innerer confronting faces thereof the plates It, I5 are provided with centre recessesvZE in which are fitted cam plates 23 that are secured in xed position through the' medium of bolts or other fastening elements 245. Ontheir 25 opposing or confronting faces the camplates 23, which plates are identicalin construction, are provided with cam humps 25. 'Ihe cam plates 23 are so angularly adjusted that the humps 25 on one plate confront the spaces on the other plate 3o between the cam humps of the second plate, or in other words the cam humps are arranged in alternation.

. Mountedon the end i201l of the beam core to rotate the beam core, and arranged between the cam equipped faces of the plates 23 is a sprocket v or thrust wheel over which is trained a driving chain 26 for driving the sprocket and consequently the beam core I2.

The aforementioned thrust wheel or sprocket comprises a body 2l of spider form provided with a hub 28 the bore of which has its ends oppositely v tapered for accommodating the tapered ends 29 of bushings 30 that snugly fit about the end I2a ofV the beam core and extend into the bearings 20, 2l. The bushings 30 are held in position on the end I2@ of the beam core between the shoulder 3| formed on the beam core and a nut 32 threaded on the free end of the part I2a of the beam core.

A binding of the elements just referred to will be such that drive will be transmitted from the thrust wheel or sprocket to the beam core I2.

In addition to the body 2l just referred to the thrust wheel or sprocket includes a removable rim 33 that is provided with suitable sprocket 55A ment the body 21 on its periphery is provided at intervals with transverse notches 35 while the rim 33 on its inner edge is provided with notches 'Y 35 that mate with the notches 35 so as to accommodate rivets 31, which rivets have their ends upset so as to be positively secured in place and to .hold the parts 21 and 33 of the sprocket wheel assembled,

Arranged in the spaces of the body 21 between the webs 38 of said body are substantiallyfrustroconical rollers S9, and for these rollers there are provided suitable pins or stub-shaftsy 40 the respective opposite ends of whichare fttedinto 4sockets 4i and apertures 42 provided in thebody 21 of the sprocket and as will be clear from a study of Figure l, Y j j As also will be clear from a study of Figure 1 opposite each of the openings 42 the rim 33 of the sprocket is provided with an oil hole 43 whereby lubricant may be introduced into an oil Ypasv sage 44 provided in the pin 4G and opening at one end and at one side of the pin;

The pin 45 for each'roller 39 extendsthrough spaced bushingsor sleeves 45 arranged within the bore of the roller 39. The sleeves 05 are spaced above and below the lateral outlet for the oil passage 44 so as to provide between the confronting ends of the bushings or sleeves 45 an oil well to accommodate the lubricant. Y

From the above Yit will be apparent that as the Ythrust wheel or sprocket rotates the core beam I 2 will also be caused to rotate or-` revolve. As the sprocket wheel rotates the rollers 39 successively engage Vthe cam humps 25 on the plates 23 in .a1- ternation with the result that during rotative movement thereof the core beam l2 is also caused to reciprocate longitudinally.

It will be understood that as the yarn isbeing wound on to the beam of the machine .the said beam as just Yexplained will be rotating Yand reciprocating with the result that the threads will be caused toA lay Von the beam in such a manner that the threads will lay on Ytop of each other at an angle instead of parallel to each other.

It will also be apparent that this invention will not interfere with the usual method of beam warping in textile establishments. As is well known presentl methods consist in rst winding a certain number of threads on a'reel to form a section, and when enough sections have been formed on'the reel, these sections are then wound on to the beam. With this invention all the sections may be wound at the same time on to the beam, and with this invention in use there will be an even distribution of the yarn over the beam with the result that the tendency of these warp sections topleave streaks in the cloth will be eliminated as will also the practice, as hereinbefore mentioned, when ner yarn is used, of Y rolling stiff cardboard every few revolutions of the beam inV order to keep the warped ends straight and allow a uniform tensionvon all ends,

in weaving. 1 Y
