To all whom it may concern.'

Be it known that l,- dosnri-i ll. Jones, a citizenot the United States, residing at -Winthrop, in the county of Suffolk, State of Massachusetts, have invented a certain new and' useful Improvement in Cep-Spinning Frames, ot whichthe following` is a specification, reference being had therein to the accompanying drawings.

The invention relates to cap spinning devices or the class in which a cap and the spindle or bobbin with which it cooperates revolve in unison.V More especially, it has relation to that type ot such devices in which the cap is controlled vertically by means ot a small dish or so-called whirlj7 throughout the spinning process, and during the relative traversing' movements j which the twisted yarn, in being wound upon the spindle or bobbin, is distributed thereon so as to be built up into the required form of yarn-mass.

ll`he invention consists in a whirl of irnproved construction; in an ii proved support for mounting a whirl7 `n proper working relations with the cap with which it co operates; in special means ot preventing the whirl from rising 'from said support during the spinning operation, as well es from being raised by the ordinary attendant upon the spinning trame. Also in means for pre venting lubricating oil from working out ot tie bearing portion oit the 'whirl-support to the exterior Aot the latter... Also in an improved cap.

The drawings show in Figure l a view oi certain parts oi a spinning frame, with an embodiment of the features ot tie invention applied'thereto, the spindle-rail and whirl-supporting rail being in vertical section.

Fig. 2 is a view in plan oi the bobbin, cap, whirl, and whirl-support ot Fig, l, and

Fig. 3 isa view on a sonewnft larger scale showing the parts ot 2, r iinly in vertical section. p

6 is a. sectional view oi the whirl separatelyr shown.

Fig. 7 is a sectional view ci? the cap ror the whirl-support, separately shown` Figs. 8 and 9 are a side elevation and a re a sit-e elelster rer Oldand well-known partsr shown therein comprise a thread-board: l having' hingedy thereto at '2, yin usual' manner, a block 3V4 carrying the guide s for the yarnw-betweenf the front rolls (not shown)v and the devices by which the yarn is twisted; alsoa spindlef rail 5, a bearing-support 6 mounted thereon, and a spinningspindle 7 ot sleeve-whirl" type" mounted inl said bearing-support and provided with a band-whirl aaround-which:

passes a spindle-driving band@ by means oi" which the spindle is rotated; and, also, a quill or bobbin 9 mounted upon the said spindle, The drawings show, further, a cap l() mouinted upon the' upper portion. ol thev bobbin and rictionally driven thereby so V as'to revolve in unison therewith, and a capcontrolling whirl l2 in `rolling peripheral contact'with the cap. Asl in my'applic'ation for U. S. Letters' Patent tiled Novemberv lO,

1919, Serial No. 336,897, the cap is coneshaped and lla-res upwardly so that? the upper portion of the cap overhangs the peripheral portion ot the whirl, whereby the cap is supported vertically by means ot the periphery ot the whirl. 815

At i3 is a rail, which is substantiallyy like the ring-rail of a ring-spinningltrame, and which carries' the whirl-support le. 'ln practice, in: converting over existingv ringtrames l retain and utilize' the ring-rails 90 thereof by applying whirl-supports thereto.

Referring nowrto the parts and features which are more immediately involved in the invention,-

Thewhirl-support le is constructed with 951' a base that is adapted to rest upon the top' ot rail 18, and usually will rest thereon, which is advantageous because ot the stability and stcadiness which are secured thereby. lt has an annular downwardly-entendiing boss 14n which occupies a hole in rail 13 around the spindle and bobbin. Such hole usually is concentric with the spindle and bobbin, and in case the rail 18 isa rin rail the hole will be one' of those ordinarily 105 occupied bythe base of a spinning ring or its holder. |The whirl-support will bevv retained in place by suitable `tastenings, as l-or instance encor more clamping-screws l5. Aplurality of screws may be employed, 1150;i

as sometimes in practice in the case ot spinning-rings and their holders, and it desired the fastening-means may be or" a character and arrangement to provide for adjustment of the whirl-support by which the whirl may be adjusted toward or from the spindleaxis, as may be found advisable or necessary in securing` proper working relations between the cap and whirl.

rlhe whirl-support is ehambered out vertically and Within the chamber leb is contained a bolster-bearing le, the lower portion ot which is occupied by steel ball 1T constituting a step-bearing The whirl is provided with a pintle or journal 1S which extends down within the bolster-beairing` and is stepped in its lower end upon the ball 17. rlhe chamber lill) is ci capacity to hold a conside ale volume oit lubricating oil, and 'tor the purpose of supplying a greater quane o' the whirl-support has for Y in an oil-receiving chamber la communicating by a small pas- Sageway ed with the main chamber lll. Chamber lac' is furnished with a hinged cover i9. .bolster-heal i6 is shown as formed with a plurality of adial iins or 'i tlanges i6, 16, i6, that with the inner surface of the wall ol chamber la" and serve to centralise the bolster-bearing. 'these pins or flanges terminate above the bottoniA of the chamber, leaving the lower portion ott the latter .unobstructed so as to provide for free circulation oie oil within such portion. v V

rlhe body oit the whirl extends in the form oi sleeve l2 down from tl e top 'ot the le. The said sleeve surrounds the upper portion of the cyl; ical shell or wall ille ot the upper portion ci the bearingchainber leb. so the whirl @overs the top of the said cylindrical shell or wall and incloses the shell or wall to a considerable distance below said top. This depending; body is provided with a ring` 2O of material or" a character which will not cut or abrade the yarn as it passes between. the peripheries oit the cap and wh l tional 7 and also oi a nature suitable tor causing the whirl to be rotated through the peripheral contact with the reyolving` of invention fonsists in coinbining the pintle with the whirl in a positively nrqed and per" inent manner by casti 9; the whirl up ie top end of a steel pin coM the j doing this by the pro essl of die-casing am enabled to secure at very low cost pert'ectly true and accurate results raidingwhirls which would not be i; ifcircl true v.the parte should be mafhined ld out together in the usual ,nner by trie aid et the machines cusnf! empio;` tor such work.

i ie body of the whirl covers and surrounds tile upstanding wall 14e of the oilafloat/o5 chamber 14h, as'already' noted, but in order to insure more eilectually against the admission of lint and dirt into sait. chamberj l provide as one feature of the invention a chamber-cover or cap 2l having a peripheral externally-threaded flange which screws down within the internally screw-threaded wall of said oil-chamber. A. central hole in tl e disk of this charnber-coveringn cap accommodates the pintle o1C the whirl, which has a close lit within said hole. For the purpose of enabling the whirl to be locked in place so as to prevent it from rising or being raised so long` as the cap remains screwed down in place, l form in the pintle just below the dish oit the chanibencovering cap an annular groove 18a, Fig. 6, and apply to the pintle a split ring 3G which partly occupies and contracts within the said groove. Contact of this ring with the under side or" the said disk will prevent the whirl from moving upward until the chambercovering cap has been unscrewed. Prefer ably the disk of the whirl is closed or continuous, except for, one or more small openinp's 12e, 12e, Fig. 29 so that the dislr of the chamber-covering cap is covered by that et the whirl and more or less completely concealed and rendered invisible. lt also is inaccessible eXcept through the said small opening or openings. To enable the chamber-covering cap to be unscrewed when necessary, l form in the disk thereof a hole or holes 21a, 2l9 Fig. 7, preferably not going entirely through the said dish. ly applaying at the top of the whirl a suitable appliance or tool having` a projection or projections capable or" being passed through the hole or holes in the top of the whirl and engaged in the hole or holes in the disk of the chamber-covering cap, and then rotating; the whirl and said cap together by means of the said applianceQ the chambercovering cap may be unscrewed to permit ot the removal of it and the whirl together. Alter replacement ol the whirl and chainH ber-covering cap, the latter' may be s"rewed bach into place inlilre manner to loclr the whirl in its working relations again. A suitable appliance or tool tor the purpose just noted is shown at 2% Figs. 3, .8 and 9. "t comprising a cylindrical bod j having` a central hole 22a to receive the upstanding central hui oit the whirh a Flange 22h, opposite pins 22, 22C projectinn,` 'roin flangeV 29," and adapted to pass through the holes the body oll the whirl and engage within the holes in he disk oit the chamber-covering cap, and a flange 22d that is lruuiled to tacilitate the turning` ot the appliance or tool in uns rowing; the said cap and screwirui` it back into place. rlhe appliance or tool 22 is applied as in Fig. 3 only when it required to utilize the same in screwing the cup 2l into place or effecting its removal.

tendency to4 retain its normal contracted' lt may be forced: out of the said state.

groove and drawn oli from the pintle whenev r it is desired to disconnect the chambercoverin'g cap from the whirl. The. partev may readily be recombined in reassemblingthem for use.

An advantage of the split ring 30 is that it constitutes a radial collar or flange on the pintle from which oil. working upward along the pintle flashes 0E outwardly against the interior of the cap-flange and of the shell or wall of the oil-chamber under the influence of centrifugal force, thereby preventing the oil from reaching the underside ot' the body of the whirl and working outward thereon so as Vto escape to the exterior of the whirl-support, to collect thereon. accumulate dust and lint, etc.` e f T he improved cap 10'shown in the drawings is characterized by having its 'downwardly tapering .conical exterior formed with a flare or taper making a greater angle with the longitudinal axis of the cap than that of the conical cap of my application aforesaid filed November 10, 1919. The increased angle is secured through making the cap with a conical portion 10'l substantially less in length than the length of the body of the cap, as shownin the accompanying drawings, which enables the desired angle to be attained without any inconvenient reduction in the diameter of the lip. of the cap at its open lower end or increase in the diameter o1 the large part of the cone. The total length ol the cap itself must be suilicient to permit the cap to be formed with an internal chamber suflicient in its vertical measurement to accommodate the total length of the conical nose of the filling-mass wound upon the bobbin. In other words, the vertical measurement of the said chamber must be somewhat greater than the length of the traverse b yrwhich the yarn is distributed up and down to produce the said conical. nose in winding upon the bobbin. In the illustrated embodiment of this feature of invention, the conical shape or" the cap is confined to the upper portion of the cap, .he lower portion of the exterior of the latter being cylindrical;

The primary aim in increasing the angle of the taper or fiare of the conical exterior of the lcap is to eliminate tendency to wedging between such exteriorand the whirl 12. With a slight taper on the exterior of the cap, the latter tends to work downward in accordance with the principle involved in the behavior @i a belt traveling around a conel pulley. rllhis 'dowr'lwamd-l tendencyy is'v accompanied by ak tendencyv to the' lwedging aforesaid.. rlfhefresult off the'wedging ispri'- marily a tendency-to'crowdfthe cap,.bobbin spindle sidewise away from the; airislot4 `the' pivot rThis causes thepintel of the' spindle to bear ,moreV against-one side of its" bearing support than against theother sidesy thereof, which not only affectsthe general ruiming of the spindle buttends to;y produceJ wear between the spindle and its bearing. A natural result is: an increased consumption of powerwhich is'appreciable'lin the; c'ase'of' the entire spinning 'frame' and isi multiplied with the number of. frames. Any incidental eflectis a more or less completeneutralization-ofthe capacityof the spindle toiindf its own center in rotating, the' consequencez ofwhich is greater noise, etc; in theI working of the frame. rlhe spindle does not run on its true center of rotation., which-` would-'bethe center of gravity; it chatters, failsl toV run smoothly, -andprobably the attainable' speed is reduced. The wedging actiongby producing more or less-of a cramping effect between tlfe cap and they loo'bbin,l tendsf tol` cause the cap to turn at'. the `same rate of! speed as the spindle andthe bobbin, andl by sion so that the action isnot' as good as when the .diiierenceor differential ist greater.

By eliminating wedgingand consequent binding or cramping. of the cap upon'. the

bobbin, freer turning. of the? bobbin'I within the cap is permitted,.which results ina. better winding-on `action and in a better tension of the yarn.

The details of the construction ofthe devices in which the featuresof thein'vention are embodied be varied more orless"` in practice.
