-aoorporationof Application om as, 1934, snm N. 'zsaoss is ouin. (ci. 11s-e1) 10 contact with any lubricant upon the ring, traveler, or elsewhere; to prevent excessive tilting'of the traveler in thedirection of its advance; and to reduce friction of the thread with the guide its it moves through the traveler.

With the above and other objectsand ativantageous Afeatures in-view. the invention consists of an arrangement of parts more fully disclosed in 'the detaileddescription following, in conjunction with the accompanying drawing, and more specincally defined in the claims appended thereto.

In the accompanvingdrawing, l

n In-Flure 1 of themawing IQ represents the A yarn, thread. or lament advancedfroin theie'edlng rolls, through. the usual thread-guide, of a spinning or twisting machineto the ban-e1 vpor. tion-'ll `of the spool N above its-base I1. The revolving spindle .i8 with its whdrl :is can-ies the bobbin. III is the vertically reciprocating traverserail supporting theholder-ZI of'the'ring` 22 of the vertical type Provided wlth tl'ie"lubriI u eating Il and uponv which' revolves my the coil isin contact withV traveler 2l also of-the verticaltype under the impulse off'the yarn 'Il which slidably engages the latter.4

My traveler, which is'of the vertical type, is formed from lengths ofsteel, bronze, or alloys 8 of any unusual,convenient,`or preferred trans- -verse sectional contour. As shown in Figures 3 and 4 it comprisesfa shank 21 having a vertical lower portion 2l and an upwardly directed rearwardly inclined upper portionl 29. Integral with 10 the lower end of the shank 21- is a curved foot or lower horn 3|. A head or upper horn 32 comprises a forwardly extendingl top portion I3 and `a downwardly directed nose portion 3l outwardly folded upon itself as at 35. The doubled back 15 portion or arm 31 of the head'lis in overlapping contact with the nose portion 3l and extends rearwardly over the top portion Il to anintermediate-portion of the latter and in" the vertical plane thereof,'where the folded portion is bent 20 into an upwardly extending -laterally directed resilient helical coil 39 beginning substantially in .the plane of the traveler and terminating in i a tip III. 'I'he coil forms aguide eye 4I for the -f e of the filament Il therethrough. In Figure 4 the upwardly extending coil 30.

'when viewed from the front of the traveler, is'uirected .to the `right of the Wertical .plane of the latter. 'This direction of the coil is required when the twist beintimprted to the lament Il is in 39 one. direction, known,4 as the regular twist". When an oppositely- `directed twist, known as reverse twist", is'being imparted, 'the coil I0 is ,l

directed t0 the left of the traveler plane as .n s i i'n Figure-5.

In operation the traveler 26 is, inrunnlng poaition, impelled around the ring 2 2 vwith a laterally forwarded tilt' under thev iniiuence, -of the iilament M passing through the guide eye or coil 39 and thence-because of the elevated'position' of the 40 latter, to the spool I6 in a horizontal plane not lower than the top of'the spool baseyl'l -which shields the lament from any discolored lubricant thrown f! from the spoolbase during their revolution 'when the base of the spool .is within the'45 ring during the traverse of the latter.l The position ofthe coil. `I0 is such that it is inaccessiblel to Aany lubricant which-may escapeI from the 'lubri` inner 'face of the ring 22 or 'from the lubri. surface ofthe traveler; .and noportion of 50 the ring and ytherefore there is no possibility of contact with ,the lubricant in threading or otherwise. f I

In broken lines inFigure 2 the traveler is shown Vin a` position of rest, The position of'the thread 5| guide '39, above the head 32 rather than below the latter and adjacent the inner lubricated face of the ring 22, maintains the lament remote from-said face even when the traveler-is in aposition of rest. f

The-elevated position of the coil 39 increases the tendency of the lament to maintain the traveler while it is in motion from assuming such .an excessive tiltas to cause the head and `foot ing in front of the traveler, who grasps the thread at interspaced points thereon between the thumb and first finger of each hand and thrusts the interspaced portion forwardly along the top surface of the arm 31, transversely thereof, against the side of the coil which yields to the thrust and admits the thread into the eye 4| in operating position. The downward and rearward curvature of the side of the coil impacted by the thread moving along the arm 31 serves to guide the thread into the eye. Not only is the threading operation instantaneous 'and certain, but at no time during the operation can the thread contact with any portion of the ring 22. 'I'hus danger of soiling by the lubricant or accumulations upon the ring or any portion of the traveler head Vis y avoided.

It will be understood that the shank 42 of my device may, as shown in Figure 6, be straight throughout its length without departingfrom my invention.

A modified form of my invention, shown in Figures 7 and 8, differs from the form shown in Figure 3 in substituting for the arm 31 and arm 44 which extends to a pointnear the rear'end of the top portion 33 of the head, and terminates in a. longitudinally directed helical coil 46, that is to say, a coil whose axial line is longitudinal with relation to said top portion 33. T'he coil 46 is in the same vertical plane as that of the traveler and permits a direct comparatively frictionless passage of the thread therethrough to'the spool or bobbin I6 upon which the thread is wound. Furthermore this coil is composite in that it is utilizable in a single structure for both a regular twist or reverse twist.

In travelers of greater width or weight than those above described the modification of construction of my traveler shown in Figures 9 to 11 inclusive is desirable, wherein a single piece of. broad material is used throughout. It is composed of the shank 48 and foot 49. The former having a rearwardly and upwardly inclined upper portion 5I integral with a head 52 including l a forwardly directed top portion` 43 and downwardly directed nose portion 54, the

portions

53 and 54 being but half the width of the shank 48.

This is due to the fact that original material of the head was longitudinally bisected. One of the two bisected sections included the bearing portion and nose portion, while the second section was bent to form, at the rear end portion vof the head, an upwardly extending laterally directedl helicacoil 56 forming an eye 58. The coil 56 is located in this instance upon the right half of the head 'for use in connection with regular I vertical shank, a foot upon the lower end of the shank, and a head having a portion bent to-provide a guide coil adjacent thereto and positioned above the head, said coil comprising a plurality of turns and extending laterally beyond the plane of the head and shank. 5 i
