It is an object of this invention to provide a yarn guide apparatus for spinning frames, twisters and the like comprising an annular member or" ring having a groove extending around its inner surface in which a ring is loosely mounted and-towh'ich yarn may be directed from a suitning frame, the yarn passing between the outer periphery of the last-named ring and the bottom of the groove in which it is disposed and then extending-to'a-rotating bobbin.

t is another objector-this invention to provide a ring for spinning frames and the like havingupper and lower annular members having their inner proximate edges cut away, so that when they are placed in superposed relation a groove substantially semi-circular in cross section will be provided for loosely receiving a floating ring and having means for securing the upper and-lower members together and also securing the upper and lower members to the ring rail of the spinning frame, and to further provide coinciding slots in the upper and lower members extending from the inner to the outer surfaces thereof and being disposed substantially tangent to the curvature of the inner surface of the upper and lower members and communicating with the groove in the inner surface of the upper and lower members to thus provide means for rapidly threading the yarn, between the periphery of the second ring and the bottom of the groove in the inner face of the upper and lower members, it being understood that the ring rail should have a coinciding slot therein to facilitate passing the yarn through the slot in the ring during the threading operation.

Since a traveler is not employed in my improved spinning and twisting ring, it is seen that the use of a lubricant is eliminated and this also insures that the yarn, regardless of whether it is a wet or dry twist yarn, will be free of lubricant or stains which normally collect on the yarn as it passes through the traveler on other types of spinning and twisterrings.

Referring morespecilically to the drawings the It indicates a bolster rail'which supports a; plurality ofb'olste'r's I I, only one of which is shown in the' drawingsi Thisbolster rotatably conventionsrefivihg means, not' shown; are connec'td for 't'rans'rriittin'g rotation tdthe spindle I3. This spindle I3 has a bobbin I4 mounted thereon on which yarn I5 is adapted to be wound.

Disposed a substantial distance above the bolster rail I8 is a vertically movable ring rail I9 which is provided with a plurality of openings 29 only one of which is shown in the drawings. This ring rail I9 is driven by conventional means, not shown, to move up and down with respect to the bobbin M so as to lay the yarn I5 onto the bobbin evenly.

The numeral 2| broadly designates the ring as a whole which comprises upper and lower ring members 22 and 23 respectively. The proximate inner edges of each of the ring members 22 and 23 are provided with coinciding substantially quarter-circular grooves which, when the ring members 22 and 23 are assembled, form a groove 24 around the inner face of the ring 2| in Figures 3 and 4.

The upper and lower ring members 22 and 23 are secured together by bolts 26 which also secure the members 22 and 23 to the ring rail I9, the ring 21, of course, being positioned in cooperating alinement with the opening 2|! in the ring rail IQ. The members 22 and 23 are provided with coinciding slots 2'1 which extend from the outer to the inner surfaces of the ring 2| and these coinciding slots 2'! are disposed substantially tangent to the inner surface of the ring 2|. In order to facilitate the threading of yarn through the coinciding slots 21 in the members 22 and 23 it is preferable that the ring rail I9 be provided been stated, other objects will appear as the de- 'scription proceeds, when taken-in connection with the accompanying drawings, in whichwith a plurality of slots 38, there being one slot 36 for each of the rings 2| and this slot 30 coincides with the slot 21 in the members 22 and 23.

Also, before the upper and lower members 22 and 23 are assembled in the manners shown in Figures 3 and 4, a continuous floating ring 3|, of substantially less thickness than the width of the groove 24 and of substantially less overall diameter than the diameter of the groove 24, is mounted in the groove 24 between the members 22 and 23. It will be noted in Figures 3 and 4 that this floating ring 3| is of substantially the same inner diameter as the inside diameter of the members 22 and 23, however, the outside diameter of the ring 3| is substantially less than the diameter at the bottom of the groove 24 in the members 22 and 23 and is thus loosely confined within the grOOVe 24. It is preferable that the outer peripheral edges of the ring 3| be rounded, as at 32, and that the ring 3| be polished to avoid breaking the yarn as it passes thereby. Also in Figure 4, it is preferred that the peripheral edge of'the groove 24 at the upper member 22 be rounded as at 33 and that the inner surface of the member 22 be polished to further prevent the yarn from breaking as it passes thereby.

It is thus seen that upon placin an empty bobbin H! on the spindle l3, an operator may thread the yarn through the coinciding slots 36 and 21 in the ring rail l9 and the guiding ring 2| and the yarn will then pass downwardly from a suitable source, such as the drawin rolls of a spinning frame, and will then engage the inner surface of the upper member 22 and pass into the groove 24 and around the outer periphery of the ring 3! and thus to the bobbin I l. The spindle l3 being driven, the yarn I5 is then wound about the bobbin l4 and, at the same time, the yarn I5 moves around the floating ring 3|, the outer ring 2| remaining stationary.

In the drawings and specification there has been set forth a preferred embodiment of the in- Gil vention, and although specific terms are em-' ployed, they are used in a generic and descriptivesense only, and not for purposes of limitation, thescope of the invention being defined in the claim.-

I claim;

Means for feeding yarn onto a rotating bobbin comprising upper and lower ring members each having upper and lower planar surfaces and sur-- rounding the bobbin, a source of yarn, a ring rail, a plurality of bolts passing through the ring mem-- bers and the ring rail to secure the planar mem-- bers together and to secure them to the ring rail, said ring members having a continuous groove at their proximate inner edges, a floating ring loosely mounted in the groove formed in the upper and lower ring members, said ring rail having an open-- ing coinciding with the upper and lower ring members, said upper and lower ring members and the ring rail having coinciding slots therethrough which are tangential to the inner- RALPH V.
