' 'z claims. (ci. sil-5s) hollow spindle then downwardly'together` and Y This invention relates to a device for the twisting of strand material and-more particularly to a device adapted to impart more than one turn 'of twist to one or more strands for each revolu-` tion of the yer. e
In such a Adevice the package or packages from which the strand material is supplied do not partake of the revolution of the flyer. The strands are drawnfrom the supply package or packages in "a, manner to form a loop which is carried by a yer around the package or packages. Assuming Vthe supply package to be mounted on a stationary axis, two turns of twist are imparted for each revolutionof the loop about lthe package. 'I'he manner in which the supply package support is held stationary while mounted upon a rotating spindle with the yarn looping about the supply package has ,been accomplished in various ways and it is the means by which this result is accomplished 'which is the feature of this invention. One of the objects of this lnventionffis to provide a simple and emcient manner vof holding the supply package support substantially stationarywhile beingvmounted upon the revolving spindle whri'ch rotates'the strands about 'the package'sup- Another object of this invention is-to provide a friction drive through -the iiyer from a stationary frame to the supply package support which will provide suilicient friction to prevent slip between the driving parts.
Another object of the inventionis to provide a drive between the different parts by means of a ifriction belt, the number of beltsbeing multiplied until the desired friction to prevent slipping is had.
With these and other objects in view, thev invention consists of certain novel features of construction, as will be more fully Ydescribed and particularly pointed out in the appended claims. In the accompanying drawings: Fig. l is a diagrammatic view showingV parts in sectionillustrating the spindle, the support for the supply packages, and the driving arrangement which is the subject matter of this invention, an assumed position of flyer drive shaft being shown. dotted;
Fig. 2 is a fragmental vview similar to Fig. 1
, showing in a section at right angles to Fig. 1 -the driving parts:
' as at I3 to loop the strands upon themselves,- which loop is revolved about the axis of the radially outwardly as at' I2 and thence upwardly spi-ndl so that two turns of twist or lay are .placed into the strands for each single turn that the l loop makes about the spindle. The upwardly extending run of the work I3 .is then guided from the machine through the ringV I4 and between feed rolls I5 and I6 and-thence lead as at I'l over pulley I8 and over suitable guides I 9 and 20 to be packaged as at 2|, the package lbeing operated by a surface drive 22,: as diagrammatically shown in Fig. 1. 'i
A suitable spindle z5 is belt' Adriven by e puney 28 which'is mounted on the spindle. 'I'he spin` die extends upwardlythrougha bushing 21 `supporting the ball bearing 28 which is held in place by av cover III, all in fixed relation to the staf tionary framework 29 of the machine.
Y 'I'he spindle is shouldered as at 3| which provides a seat for a flyer designated generally 32 and which consists of a hub 3l with a lower disk $4 secured at one end thereof and an upper disk' 3l secured at the otheriupper end thereof. -A
guide sheave or pulley 3B is located in a recess 31 `in this hub 33 and has its inner edge tangent with a hollow bore 38 in the spindle so that as A the work. is led downwardly through the hollow Fig. 3 is a sectional view illustrating the mounting of 'one of the shafts carried by the flyer;
Y- Y.'I'heinvention illustrated in this applicationforms a part of a larger machine which is shown spindle and 'over the pulley 38 it may extend radially' outwardly over the pulley or sheave 39 which is located in recess Il in the edge of the iiyer disk .l5 and rotatably mounted in bearings 40. I
Above the ilyer 32 the spindleis also shouldered for' the reception of ball bearings'lzand 43 for rotatably mounting the supply package support or creel Il comprising a hub 45 engaging the ball bearing and a sleeve IB nxed on this hub from which a deck platell extends at right anglesto the hub and spindle. g The deck plate e is flanged as at I8 leaving a hollow portion I9 in which the yer drive shaft extends.
Supported by the disks-34 and 35 (see Fig. 3) are sleeves 50, each of whichis provided with a ange 5I and a reduced 'threaded portion 52 which extends through an opening `Iiin the plate 3l and may be secured in diierentrposi- -tions of rotationin the opening by means of a nut B5 and washer 56. The upper end of this sleeve is also enlarged toY extend through and be rotatably mounted -in an opening il in the plate 35'. The lower end of the sleeve illcarries a ball bearing 58 while the upper end carriesa 1 ball bearing I9, both of which serve to rotatably l mount the shaft 80 in a positionwhich is-off in mee-pending application serial m1511859.
The supply packages are designated I0 from `which tne'strande ef materiel VHeleen into the center with relation" to theA rotatably mounted vsleeve (see Fig. 3). This shaft 60 canies a pulley designated 8| vat its upper end with an Vamzmla'r V-shaped race or groove 82 in its periphery. 1 The while it is held in place by a nut 64 and lock washer' 65. At the lower end there is a pulley or sheave 18 which has an annular V-shaped race or groove 1| in its periphery. A hub 12 engages the ball bearing 58 and is held in place by nut 13 and lock washer 14. Closure caps 16 extend over the ball bearings. The flange 15 extends over the closure cap 16 while a flange 11 fits into a groove in `this lower cap.
The stationarybushing 21 is provided with a pair of annular V-grooves or races 80 and 8|. A V-belt 82 engages the V-groove 80 and extends to the pulley or annular race 1I while a V-belt 83 engages the annular race 8| and extends to another similar pulley 10 for driving each of the shafts 60.
The hub 45 of. the creel or supply package suppont is also provided with a pair of grooves or annular races 84 and 85, a belt 86 engages the annular race 84 and extends about the annular V-groove 62 of the pulley 6| at the upper-end of shaft 60 while a companion Vfbelt 81 engages the V-groove 85 and extends about the annular groove 62 of another pulley 6I of a diametrically oppositely located shaft 60 on the other side of the fiyer so located as to be in dynamic balance with the flrstisaid shaft. It will be'readly apparent that any number of such shafts and belt arrangements may be provided to secure the desired friction necessary for the conveying of the drive of the flyer from the fixed race inthe stationary portion 21 through the iiyer and back to the support for the supply packages or creel.
It will be readily apparent that if the diameters of the raceways 80 and 8i are the same as the pair of annular races rotatable with said shaft and means fortensioning said flexible means.
diameter of the vraceways 84 and 85 and the pulleys 6I and 10 are the same diameter, rotation of the shaft 88 which is caused 'by revolving the flyer about the spindle will convey to the creel or supply package support a rotation in the opposite direction to the rotation of the flyer in the same amount that the shaft is rotated by the belt driving thershaft from the annular raceways 80 and 8 I Thus the creel or supply package support will remain in its same relative position to the frame or stationary assuming no slip occurs -in the drives which are provided. I have provided a suficient number of drives so as to obtain sumcient friction so that no slip will occur.
By revolving the sleeve sa' which has a shaft so to one side of-,the center of the portion 52 which extends'l through the opening 5I I may tighten the belt as the sheaves are thus moved relative to the axis-or the spindle. 3
By this arrangement of V-beits driving from a xed annular raceway to the flyer and from the shaft rotated in the flyer back to the vcreel or supply package support, I have been able to provide a very simple and efficient means for mounting the creel or supply package support upon the spindle so that no motion of the supply packages occuras the spindle rotates while permitting of. the loop to pass about the supply packages as rotation occurs.
I claim:
l. In a strand twisting dev ice,a spindle, a-
carried by and rotatably mounted in the flyer and y positioned to be'revolved about said spindle, a
