To all whom t may concer/n: Y Be it known vthat we, EDWIN O. Ron/,and LiioNAnD P. FnniDnn, both citizens of the United States of America, and residents, re-

spectively, of New Bedford, inthecounty of;

Bristol and State of Massachusetts, and New.

lYork, county and State of New York, havel vinvented certain newY and useful Improvements in TeXtile-Coiling Machines, of which and exact de-v the following is a full, clear, scription.

This invention relates to improvements in machines of the kind generally yknown inthe textile trades as can coilers, forthe reason that they are usually used tocoil a 'web or.

Vsimilar collocation of textile fibers, usually called a` sliver, in cans or other receptacles One trouble experienced with all prior.

machines of the kind,` so far asthe appli-` cants are aware, has been changes in humidity or'temperature, and the developmentof static conditions have interfered with the correct functioning of themachines. #Such prior machines have also been unable -to coil uniformly and satisfactorily, even un-.

der favorable conditions, light or fine slivers as well as they did the. coarser ones.

One of the objects of this invention islto" provide a machine rwhich is capable of han-- dling a complete range of slivers, including the ,very fine ones, without interference or interruption because of the degree of fineness or because of unfavorable atmospherick or.

static conditions.

y Another object of the invention is topro-` vide lstop motion devices controlled by the sliver for halting operat-ionsof the vmachine when certain conditions arise. xNhile this mechanism may, forexample, be so .constructed as to be called into play by either the accumulation of the sliver in the cans or by a break or other' interruptiony in the supply of sliver, the use of both is preferred in the present embodiment, thereby pre- -,mechanism as is shown in Fig l;

line 4&4 of Fig. 2.;

:venting the machine from packing the sliver-v in thelcanssotightlythat rthere is difficulty later in satisfactorily kuncoiling it and at chine hasjstopped because the can is filled or because of a break or. lack of material to work upon. .f

' l/Vhile in the accompanyingI drawings the.

improvements are shown iii-the form they take when appliedv to orfused inconnection with a carding machine, it is obvious that the various parts may belmodifi'ed and rearranged to cooperate with 'other machines L;

or sources of -'supply of material, v. v f With the foregoing and incidentalobjects invievv, the. inventionconsists in a novel construction and arrangement of parts, the

novel features of which-are' pointed'out in.

the claims and a preferred embodiment of which is shownin the drawings accompanying andv forming a part of this specification.

The embodiment shownfin the drawings is as before indicated, a satisfactory one for use in receiving and -eoiling a sliver of fibers as delivered from' a cardingmachine. The mechanism yisso arrangedjthat the fibers are removedfrom'the delivery roll of thel carding machine and brought into what may, for

iodo i convenience, be termed a loose strand which i is, at thebeginning of the operation of the machine, passed through suitable guides and into engagement ywitha pair of feeding rolll ers. Theserollers are so' mounted that they deliygr,thesli've'a tothe interiorr ofthe can" y through an opening. or passage' Which .does not inove relatively to the 'rolls and which is so short that there is substantially no resistance to the passage -vof the lsliver applicants the feeding rollers are, so mounted that a long guide is necessary to conduct the material from the rolls into'ithe..can..and this guide has a movement relative to the feeding rolls. Suchl along-guide, coupled With its relative movement, makesuitnecessary `rfor v"the rolls to pits-h the sliver-through the guide. AIt is Lobvious that this'is funlsatifactory for hand-ling Av'tine slivers, for eiiample, of silk, :and that the movement"` of even nfairly coarse material mayeasily be interfered ivithby the idevelopment-fof a static Condition orbyy unfavorable ldegrees of.temperatnreor humidity.

lThe ypreferred embodiment also comprises two stop motion connections.' @ne ofLthese spending, receptacle is packed toits intended y capacity the v'packed'material acting-against a movable head f afl/ug l or' other progection into va positionivhere it ivillpengage and actuate 4a stop motion element. v'The othery stop motion connectionsfeoniprise aV member which is, in the preferred form,

lBoth 'the gearing for drivingrthe ring gear 24 and the head moving therewith, and the y gearing for driving the rotary can base 81, 'i

tation of the .basewillfcause a corresponding rotation of the can.

The ring-'gear 1% is, Yasbest shown in '-Figfloose'ly mounted in al ei'reular bearing 36 in, a plateVV (see also'liigf 2).. forni- Ving Va vpart of the machine framing. Integral vWfiththe ring geare are llugs 38 Whichform a convenient means -by'ivhich polished metal plate-89 may be'secured to and caused to turn with the gear. This plate and vits supporting connections form .what is hereina-fter referred to asv the movable `head forthe can. i

Rigidgyvith the main frame 111 is a plate 41,slottedas-at, Fig; 2,' torserveV as a guidefor the Web of fibers coming from the 4`delivery roll 11. 3F rom the slot t2 the fibers passthroulgh a guide 48, y.which is so constructed as :furtherto collectthefibers into Whatlias,"for convenience, hereinbefore been termed a `loose strand. 'The guide d3 preferably on or forms a partof a lpivoted trumpet 44. The'sliver passes frointhe guide 'downward through an eye at the "trumpet 14 is rotatable about afhorizontal axis asvshoivn'at'linfhligil. l

Thefeed rollers t? and 1S arev attached, respectively,v toshafts l52 and 53, y.iournaled at'tliei-r ends in bearings supportedby the ring gear 24 and which arepreferably of the -oilless type'. Secured'to the shaft 52 is agear 54 protected by a1 housing and extendingv through awsuitable opening in the ring gear 2t into engagement with a stationary eircular rack 'seeured to the plate 37. The construction isfsuoh that when the del liveryuoll 11 and Athe'gearing previously described are put in inotionftherin@ gear 24,' and plate 439 attached thereto, will rotate `c'ounterclo'cktvise (Fig. 2), andthe gear "54C willvcooperate with-the stationary` circular rack 56 to feed the sliver or strand of materialV down through an opening or a short guide such -as 61, formed-"on or secured to the plate 39. The short gu'ide'is, in some respects, preferable to simply an opening, as its top can be formed so as to conform somewhat tothe configuration of the feeding' rollers and thereby prevent the fibers from remaining in engagement With and being Wound around the rolls.

From the foregoing it will be'seen that the construction is such that the feeding rollers are mounted in closejuxtaposition to the opening in the rotary head, and that, in

` fact, the material is practically delivered to y lthe interior of the can Without having to be pushed or forced through a'chute or guide `ofsubstantial length. it will lalso bessen that there is no movement Vof the opening or guide 61 relative to the feeding rolls'47V and 48. The advantages of these features have already been pointed out in a general Way. l i I Y The stop motion devices hereinbefore referred to may comprise any suitable electric or belt shifting mechanism, but in the pres-` ent instance the showing is a more or less conventional one, of mechanism ofthe Ybelt shifting type. A shaft, which may be movable endvvise-.to loperate a shifting fork, is shown at 57, Fig. 1. This shaft, vas is usual in suoli constructions,may be latched in one balance yor spring, notshorvn,4 when the bellv fl D fill,

position by a Weighted bellfcrank 5,8 and moved to thel other position by a' countercrank is lifted out of engagement with a collar 59 or other suitable projection onthe shaft`v 57. This bell crank isv connectedl by the usual Wire or rod 61 to an. arm 62 rigid with the trumpet 44. ,It is apparent that if the trumpet 44 is turned counterclocl'rwise (Fig. 1) on its pivot 51, the bell crank 58 lWill be lifted to release the stop motion mechanism.

The trumpet 44 is lifted or rocked, as just mentioned,either when thev can 35 has become packed to its capacity or ivhen the sliver or strand of'material has been 'broken the rotary head, comprising the ring ygear 24 and the polished metal plate 39, lhas vone 'f or more lugs such as shoivn at 63. Vhen the can has b-een filled to its capacitythe movable head will be lifted by the material,

thereby raising the lug 63 until it Will'strike a suitably'formed portion 64 on the trumpet 44 and rock the trumpet far enough to act through the connection 61 to free the stopA motion mechanism.

the sliver breaks or the supply of material becomes exhausted, the ring gear 24' is provided with a shoulder or boss 65 (Figs. 2 n

portion 68 which serves -asan additional weight at vone side of the pivotalsupp'ort fo r,

the paivl.r The normal position of the paivl is shown in Fig. 7, in which position it Willf` I clear the shoulder or extension 64 on the trumpet 44. lThis is what is,` at certain points herein., referred to -as the ineffective position of the paivl. y

n In this ineffective position-one edge of' the 'paWl is 'inf Contact With al pin 71' pro- ,Y ]ecting horizontallyv from' the head ,72 of a V bolt 73, supported for longitudinal movement in the lug'l65.k Surroundingv4 thebolt 73 is a light spring 74 `Which in the normal position Vof the parts, that is, While the sliver 'is running through the machine, lis slightly compressed.' between tliellug 65' and a pin 75 extending laterally Vfrom the bolt 73.

The head 72y ofthe bolt isr slotted, as indi' .cated at 76 (Fig. 2) to cooperate with a vpin 7 7k extending upward from the ring gear 24, thereby holding the bolt against rotation.

As before stated, the guide or trumpet 461 isrotatable about a vertical axis. Rigid with' the/guide is an arm 81 suitably slotted ff 'I to engage a pin extending upward from the l bolt 73. When the sliver is running through the` machine it Will hold the guide 46 ink the position inV Which it is shown inFig. 2, but if the sliver is brokeny orthe supply of material forming it Vis exhausted, the `guide Willbe freed and Will then beswung to the position indicatedby the dotted lines' `82, by the spring 74 surrounding` the bolt 7 3.l This Will cause thel pin 711V (.Fig.' 7 )V to rock the pavvl 67 on its pivot and'bring the edge 83 thereof into or Vpast a vertical'posi-n tion, invvhich position the' upper Ytip of the" paivl Will be raised high enough to engage the shoulder 64 'of the trumpet 44 andl rock thetrumpet in such Wayas to vactuate the` stop motionV connectionr 61x to Varrest the movement yof the mechanism.

In Figj2'the.positionI ofthe can 35 is represented by jdotted outlines, from which" it. Will `be seen that the axes of rotation .of thee-an and of the ring gear' 24 are notl in 'o alignment. lTn other'wo'rds', one is ofi' center ywith, respect to the other.v lThis "causes t1 sliver to be coiled,"'as indicated more or les: diagrammatically at 84, Fig. 3.' This coiling continues until the can is full, when the coil of material `vvill come in Contact with the underside of the ypolished metal plate 39. kThe plate Will thereafter serve to pack the, coiled materialdoivn in the'can', doing; this uniformly vand AWithout disar-l rangement of the sliver. The packing con- Lave-,921

tinues until the coiled material is packed closely enough to beginto'lift the plate 39, and ofcourse the ring vgear 2li and .the part-s supported thereby. This will disengage the gear 54 from the stationary circular racl 56 and will, as before described, bring Vthe lug up to a positie-n -where it -ill engage the shoulder 6l on the trumpet lei and operate to stop Amotion connections.
