movements are imparted to the yarn guide 33 by mechanism similar r to that shown and described in my Letters Patent No. 1,493,721 dated May 13, 1924.

The pairs of tension discs 29 are of usual construction for applying tension to vthe yarn and they and the yarn guides 28` and 30 are carried by a suitable bracket 37 se- 2cured to the upper portion vof the main frame of the machine. Y Y Y l'lhel yarn rectifying devicer27 comprises sinuously formed round wire o forming a series of connected arms 38 which divergev Vvoutwardly in alternate succession `yarn passage 39 formed byand from a between them, as shown in the drawings. One end :of the wire forming the yarn rectifying de- .objectionable loops therefrom without placing any harmful tension thereon so that when the yarn reaches the tension discs 29 passing over the roller 31 will be and 43, respectively,

lper portion of .supplied with there will be no danger of the discs stripping or displacing one or more of the threads or filaments relatively to the others and thereby forming thread or filament loops ion `the sides of the yarn, when yarns composed of loosely twisted threads or filaments are being wound. Y

AThe'emulsion applying` roller 31 extends longitudinally of the machine with its lower por-tion in a longitudinally extending emulsion-supplying trough 41 which. is supported by end brackets Y42 of the machine frame.,v The roller 31 is carried by a shaft 43 having its bearings `in the end walls of Vthe trou`gh4l. v VThe shaft 43 and roller 31 are rotated by a belt 44 which passes around suitable pulleysj45 'and 46 onthe shafts 20 so that duringthe operyarn strand 26 oiled by the lilm of emulsion on the roller. ,The upthe roller is being constantly a thin film of' emulsion from the emulsion contained .within the trough v41 and `into which. the lowerhportion ofthe roller'extends. Y y o The yarn guidingrod 32 overpwhich the yarn strandv-26 `passes after it leaves the ationV of the machine, the

lemulsionfroller 3l,` extends longitudinally of f the roller. 31 andhas its end portions supported by bearings 47 on the trough 41. This rod 32 is formed of'glass or other suit# able wear resisting material.

Extending longitudinally of the trough 41 Vis a horizontally arranged bar 51 supported by groovedf'rollers 49 in a manner to permit y the bar to be longitudinally reciprocated. The rollers 49 are journaled on bracketsV 50 on the trough 41. The bar 51 isfreciprof cated by a lever 52 which is fulcrumed at 53 on a bracket 54 projecting upwardly from one of the end standards 2 of the machine frame. The lower arm 55 of the lever 52 has a cam slot 56 formed therein'into which extends a pin 57 projecting from the builder frame 13, whereby, is 'raised and lowered, the pin 57, working in the slot 56, will rock the lever 52 back and forth.' rlhe upper arm 58 of the lever 52 is connected by a link 59 tothe 'bar 51V to reciprocate the bar 51 when the lever 52- is rocked under the influence of the builder frame 13. The arm 5SV of the lever Y52 is made in two parts which are longitudinally slidable relatively to each other and which may be secured in different position of adjustment by a suitable bolt-and-slot connection 69, to increase or decrease the distance between the lever fulcrum 53 and the link 57 and thereby vary the extent of movement of the bar 51.

- The bar 51 carries a bracket '61 which is secured thereto by means of a screwr62 passino' through a slot in the'bracket 61 and sciewed into the bar 51. By loosening the screw 62, the'bracket v61 may be adjusted when the builder frame' .the rod 32 to the yarn guide 33 and ad- Y jacent to the same side ofthe `yarn strand extending between the yarn` guide 33 and the cone 22 is a vertically arrangedbar 64,

the upper end vof which is secured to a bracket 65 carried by the bracket 6l.L The bracket 65 is secured to the bracket 61 by means of a screw 66 which extends through a horizontal slot in the bracket 65 and enters l the bracket 61 and permits the vbar64 lto be adjusted horizontally with respect to the rbracket 61 androller 63 toward andfrom` one side of the yarn strand 26. The roller r63 maybe formed of porcelain, glass ror other suitable wear resisting material and the bar 64 may be constructed of steel or other sui't- .Y

able wear resisting material., The bar 64 has a Yvertically-extending', thread-engaging vsurface 67 which extends throughout and beyond the entire distance of verticaly travel of the yarn guide 33 l gain movements in building yarn upon the cone 22, during the vwindingoperation', so

that the yarn 26 extending between thefyarn during its traverse and guide 33 and the cone 22 maybe engaged by the bar 64v in all positions ofthe yarn vguide 33.v l t During the winding operation the pull of the cone upon the lyarn 26 holdsv the yarn against the roller 63 land bar 64 as they are moved from the position shown by full lines i-n Fig. 1 to the position shown by dot-anddasli lines therein and back again. Thus the :ylaggee is erased' a Ymove yisa: and 'forth laterally .of its line 'of travel over the'broad j Wearing surfaces of the' yarn guides `v30 and and the yarn' guiding rod 32, thereby distributing Ithe Wear over 4broad areas 'and preventing the cutting of thesel parts by the lrictiono'f the yarn thereon.
