rEX'riLn MACHINE.

Application led February 21, 1922. Serial No. 538,190.

To all whom t may concern:

Be 1t known that I, EDWARD B. Fms'rnk,

a citizen ot the United States` residing in- Boston, in the county of Sufi'olk and State of Massachusetts, have invented an'lmprovement in Textile Machines, otl which the tollowing description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to textile machines of that class in which are employed a rotate able spindle, a spinning or twisting ring and a traveler mounted on said'ring to be revolved thereon by yarn, thread or cord wound upon a bobbin or spool mounted on said spindle.

The invention is especiallyv applicable to machines of the character described, which are employed for spinning or twisting the yarn, and in the present instance is shown as embodied in a twisting machine or frame to which it is particularly applicable.

Machines of the character described are limited in their production to the speed at which the yarn can be drawn through the traveler. by the rotating spindle, which in turn depends upon the amount of heat generated in the traveler byv trictional contact of the traveler with the spinning ring -on which it is mounted and around which it is revolved. In twisting trames as now commonly constructed, a plurality of strands taken from individual sources of supply,

' usually spools, are ted by ypositively driven feed rolls to the spindle and said strands are twisted into 'a single strand or cord by the revolving traveler and .the rotating spindle. In s inning and twisting frames as now common y constructed and known to me, the traveler is mounted on a spinning rino' which is stationary in the usual ring rai, and whenthe cord is placed under tension by the revolving spindle, the traveler is engaged with the stationary ring at a given point or points of the traveler, and

said point or points of the traveler remain in engagement with the' ring while themachine is in o eration. As a result friction i revolved, the speed of the spindle is limited since, from a practical standpoint` it can not be revolved at a speed suficiently high to heat the traveler to a point or degree where the latter will weaken or otherwise damage to provide machines of the character dep scribed, in which the speed of the spindles may be greatly increased without danger of heating the travelers to such extent as to weaken, damage or burn the fiber and therefore without danger of interrupting the operation of the machine, and'witlrconsequent increase in production of the machine.

To this end provision is made for perodi- 1 cally heating and cooling the traveler while the machine is in operation and Without interru ting the latter, whereby the traveler may revolved at a relatively high speed for a predetermined length ot time with,

one portion of the traveler in contact with the ring, and then revolved for another period of time with another portion ot' the traveler engaged with the ring and with the first mentioned portion disengaged therefrom and cooled by the air through which it is revolved. This alternate heating and cooling oi dierent portions of the traveler serves to localize the heat in different portions oi the traveler, and enables the traveler and the spindle to be revolved at a materially increased speed without interrupting the operation of the machine, and in practice the spindle speed has been increased to over 3500 revolutions per minute without detrimental effects.

In the present` instance is shown a novelv construction and Varrangement of traveler and spinning ring preferred by me and with 100 which the desired results may be obtained.

The traveler herein shown is provided with a plurality of contact points, -and the spinning ring herein shown is composed of a stationary ring and a movable ring coop- 105 erating therewith, and the contact points on the traveler are arranged with relation to the spinning ring so that some of said contact points are engaged with said spinning ring, while others are disengaged therefrom, 11o

incasso which condition or arrangement of the contact points is reversed by axially moving the movable ring. i

Provision is made for automatically movinsaid movable ring.

hese and other features of this invention will be pointed out in the claims at the end of this speciiication.

Figs. 5 and 6, details in section and elevation to illustrate the engagement and disengagement ot ditlerent contact points of the traveler.

F ig. 7, a front elevation or' the twisting frame shown in Fig. 1.

Figs. 8 and 9, details of the movable ring.

Figs. 10 and 11, details ot the stationary ring, and llligs. 12 and 13, details of the stationary and movable ring assembled together.

'llhe twisting frame or machine illustrated in Figs. 1 and 7 is of usual or known construction except as will be hereinafter pointed out, and for the purpose of this invention, only a suiiicient portion or' the machine necessary for a clear understanding of the present invention is illustrated.

Referring to Figs. 1 and i', at represents the stationary spindle rail upon which is mounted the spindles t, only one of which is shown, said spindle having the usual pulle c by which it is rotated. Cooperating with the spindles b is the ring rail d which is vertically reciprocated in a manner well understood. The ring rail al carries the spinning ring through which the spindle b is extended and with which cooperates the traveler through which the varn or cord e is drawn as the latter is wound upon the spool or bobbin f mounted on the spindle b to revolve therewith. The yarn or cord e ispassed through the eye of a guide 10 attached to a cross bar 12 of the framework of the machine, and is 'fed forward at a predetermined speed, by feed rolls 13, 11i, 15. which are positively driven in a known manner so as to feed the yarn at the same speed or rate it is wound upon the spool. ln the present instance, the spinning ring is composed ot two rings or members 16, 17 shown detached in lFigs. 8 to 13 inclusive. The ring or member 16 may be designated the4 stationary ring and the ring or member 17, the movable ring.

These rings or members are concentrically arranged, and preferably in contact with each other, and are further connected together so as to he handled as a unit while permitting movement ot one with relation to the other. l

lln the present instance the outer or stationary ring 16 is provided with inclined. slots 20, herein shown as three'in number and arranged substantially 120 apart, and the inner or movable ring 17 is provided with three studs or pins, which extend into the inclined slots 20, and two ot which marked 21 are made so as not to entend beyond the outer circumference ol the stationary ring while the third pin or stud marked 22 is made long enough to extend beyond said cir- :7

cumt'erence to aii'ord means by which the inner ring may be rotatively oscillated with relation to the outer ring and at the same time be moved axially by the walls oit the inclined slots lcooperating with the said studs or pins.

ln the present instance, the inner ring is rotatively oscillated by a path cam 23 in a plate 24: aihxed to the spindle rail a or other stationary part of the machine.

'llhe stationary and movable rmgs 16, l?, have cooperating with them a traveler, prei'- erably of the construction herein l shown and comprising a substantially triangular shaped body portion 25 provided with arms 26, 27 extended from the lower corners thereof and having a curved arm 28 extend ed from the upper end oi" said bodv portion. 'llhe body portion 25 is provided with a linger 29 which forms a guide for the y or cord e through which the latter is dra .1. by the spool f when the latter is rotated.

'lhe arms 26, 27, are each provided v slots or recesses 30', 31, for the recepties the lower edges of the rings 16, 17 respeo tively, the bottom walls ot said recesses conn stituting tour contact points of the traveler, which are engaged with the rings 16, 17, will be described.

rlhe curved upper arm 28 extends over the inner ring 17 out of contact therewith "i is desi ned to be engaged with and disend gag-'ed rom the inclined upper surface 32 of the outer ring 16, and constitutes another contact point ot the traveler. The body portion 25 of the traveler is provided with lug or projection 33' which is engaged with and disengaged from the inner surface of the inner rin'g 17 and constitutes another contact point of the traveler. lt will thus be seen that the traveler is provided with a plurality ot contact points, which in the construction herein shown are six in number, and these contact points are arranged with respect to each other and to the stationary and movable rings, so as to form two groups oit three each. @ne group comprises the curved arm 28 and the bottom walls of the recesses 31 in the arms 26, 2l", and the other group comprises `the projection 33 and the bottoni walls or the recesses in said arms. 'llhese groups of contact points may be conveniently designated group 1 and group 2.

The contacts in group 1 cooperate with lill@ seen that when the contacts of groupl 'are engaged with the rings 16, 17, as represented in Fig. 6, the contacts of group 2 are disengaged from said rings, and when the cony tacts of group 2 are engaged with the rings as represented in Fig. 5, the co-ntacts of group 1 are disengaged from 4said rings.

Further it will be noticed that the contacts of group 1 engage the upper portion of ring 16 and the lower portion of ring 17, and that and thereby rupture the same.

be observed that when the contacts of onegroup are in service, the conta/cts of the other the contacts of group 2 engage the inner surface of the ring 17 and the lower portion of ring 16.

It will be also seen, that when the traveler is drawn around the spinning ring with contacts of groupl in service as represented in Fig. 6, the heat generated is local. ized in different parts of the traveler, to wit, at the end of the curved arm 28 and at the bottom walls of the recesses 31 in the arms 26, 27, and when the contacts of group 2 are in service as represented in Fig. 5, the heat generated is localized at the projection 33 and at the bot-tom walls of the recesses 30 in the arms 26, 27.

Localizing the heat at a plurality of points in the traveler, and periodically engaging and disengaging the said points', venables the traveler to be drawn around the ri'ng at a materially greater speed for a given length of time without heating the traveler and the guide arm 20 thereof sufficiently hot to weaken, damage or burn the yard or cord e It will also group are out of service and are cooled by the air through which they are revolved'.

The periodic shifting ofthe two groups of contacts on'the traveler is effected, as herein shown, the path cam 23 in the i pla-te 24, which path cam is shaped to effect a limited rotary movement of the movable ring 17 alternately in opposite directions. The rotary movement of the ring 17 in one direction causes the pins 21, 22 to travel up the inclined slots 20 in the stationa outer ring 16 andthereby move thering 1 axially upward into the position shown in Fig. 5, and' rotary movement of thepring 17 in the opposite direction causes the pins to travel down in the slots 20 and thereby lmove the ring 17 axially downward into the position shown in Fig-6. The cams constituting the walls of the cam path 23 are preferably of substantially equal length and number, and therefore it will be seen that the periods of time groups contacts every four seconds.

The ring 16 may be held stationary'in the ring rail in any suitable manner as by screws 36, only one of which is shown in Fig.-1, which engage the top surface of the ring, and by a screw 37, which engages the. outer' circumference of the ring.

The rin indicated )y dotted linesin Fig. 1, through which the pin 22 is extended `and which allows said pin to be moved b v the path cam.

In operation with a twisting frame, such as herein represented, the, traveler has been revolved about the spinning rings 16, 17, with the spindle b making 3,50() revolutions per minute,'and a cord composed of ten strands hasbeen twisted and wound upon a rail d is provided with a slot B8 spool of five inches in diameter, without weakening. burning or otherwise injuring the fiber or cord, whereas with twisting frames of the construction known to lne and commonly used, the maximum speed of the spindles is about 1800 or 200() revolutions per minute.

When the machineis in operation and the traveler is being drawn around the .spinning ring at the relatively high speed, it is forced outwardly under the infiuence of centrifugal force and effects the engagement of the-arm 28 with the inclined surface 32 of the outer ring 16 when the movable ring 17 is in the position'shownl in Fig. 6, and when the movable ring'17 is moved axially'up into the position shown in Fig. 5, the centrifugal forcebrings the projection 33 into engage- 4ment with thel .innerl circumference of the ring 17, which prevents the contact arm 2S being moved out sufiiciently far to engage the outer ring 16.

The rin s 16 and 17 are preferably sha ed substantie ly as lherein shown. so that t ey plate 24 cooperates directly with the movable ring 17 in that the pin 22 is extended into the path cam 23, but it is not desired to limit the invention in this respect, as it is evident that all the movable rings of all the spinning rings carriedby-the ring rail d maybe operatively connected together and to a single cam, so that the latter will operate all the movable rings to simultaneously shift the travelers thereon. One embodiment of the invention is herein shown, but it is not desired to limit the invention to the particular construction shown.
