Referring' to the drawings and to the particular embodiment of our invention thereA shown. we have' therein illustrated in lgs. 75 l to 12 inclusive a machine wherein the spool. carrying the tutt yarns woundv there# on, may be placed and held in such relation to the tubes of a tube traine that, by a single operation, the entire series ot' tutt- S0 yarns inaybe placed or inserted with great certainty and accuracy7 through the tubes by suitable yarn-placing means, herein a seriesoi needles, one for each tube.

Referring lirst to the preparation of the S5 tu'ltyarnsprior to installation in the tubingf niachine we have shown in lligs. i3 to 1,7 inclusive ineans whereby the tutt yarns, ai'ter being wound upon 'the spool in the spooling machine7 inayv be held separated, 90 and maintained in such separated condition while placed in the tubingr machine so that tt y niay 'be drawn accurately through the `.ies of the tube inclusive we form ot' spooling machine -lv is represented in Figs. 13 and l5, the. same being provided with well-known mechanism t'or receiving the spool 5 and windingthe tul't yarns about the same. .During such operation the yarns unwind from bobbins (not shown), the `usual reed or separator (i being provided which presents upright pegs or their equivalents T for separating and keeping separated the individual yarn strands or groups ot' strands as the-y pass to the spool. The comb is supported with its teeth in upright position by a suitable holder S immediately beneath the tut't' yarns as the latter p ass from the reed to the spool, so that, when the comb is elevated (Fig. 1(3) the teeth are caused to pass between the sets of strands, as shown in Fig. 1.1.

llvhen constructed of sheet metal the lower edge of comb is preferably turned or curled over on itself, as shown, and is adapted to rest in a groove or pocket in the holder S. This consists of a cross-bar extending between the upright end supports 9, which latter are slidably mountedl in brackets l() secured to the frame of'the spooling machine. F or raising and lowering the reed the end supports are each provided with rack teeth 11 which mesh with the pinions 12, the latter being fixed to the shaft' 13 extending transversely the machine beneath the reed (S, each end of the shaft being pro,- vided with -a handle 14 whereby it may be turned and the comb raised 0r lowered at will.

The comb, when inserted in the holder, tits between two transverse pins 15, so that the teeth of the comb are caused'v positively to` aline with the pegs in the reed and to pass with certainty between adjacent yarn 'strands lor s'ets of strands when the comb is raised.

After the spooling operation, the comb which has previously been inserted in the depressed holder 8 and is then positioned as shown in Fig. 15, is-elevated to the position shown in Fig. Gby turning the handle l-l, each set of strands entering a separate space between the teeth of the comb. Suitable means for maintaining the holder elevated arc-preferably provided, such for example, the pin 16 fixed to the lower end of the supporting rod 9 and adapted to be yieldably clasped. and" held by the stationary spring clip 17 when the holder and comb are elevated.

lilith the holder elevated, the yarns are prevented from slipping out of the comb by the application thereto of a cap piece or retainer 1.8, which latter preferably consists of a bent or turned over metallic strip adapted to slip over. the points of teeth (as shown in Fig. 17) and close the mouths of theslits against the eiiit of the yarn strands, preferably, however, without clamping or gripdescribed.

lThe attachingr springs2() arc preferably ping the. yarns or otherwise preventing their free longitudinal dral't between the teeth.

The cap may be retained on the comb in any suitable manncr as. l'or example. b v

means ol a resilient linger piece 1.) (one ol'4 which is shown in Figs. 1l and il) riveted or otherwise secured` one at cach end of the comb, and having a hooked end which over-.

may be performed, the comb cannot be accidentally displaced. In the described embodiment of our invention (Fig. l1) we have shown the comb provided at ,each end with an attachment member, hereiniir the form oila spring 20. l`hejlal ver has an eye .l which (sce Fig. 5) mayj, slipped over the small pintle. 22 at the end of the spool 5 and employed'to? attach the. combv to theI spool, the former having first been laid' flatwise against the wound-on yarn. AThe wound-on yarn strands can then be severed, leaving them infthe'condition represented in Fig. and the'spooling operation can thereafter proceed in the usual manner, and the operation repeated as -toanother spool as above each provided with means, such as the angular clip 23 whereby the operative can readily apply the spring eye 21 to the pintle or release the same therefrom. It will be seen that this provides a means for permanently holding the comb in definite relation to the spool and the wound-on yarn .strands until required tor the tubing operaprises end frame members 2i between which,

near the front of the machine, there extends a bed 'piece or plate 2 5 (Fig. 3). The bed plate serves as a support or rest for the tube frame (see Fig. 9), which latter is inserted in the machine 'with the tubes 26 resting on the bed plate and their small ends pointing inwardly, the tube connecting bar 27 resting against the 'front edge of the bed plate.

the indiridual tubes, sneh means herein be ing embodied in the torni ot' a swingingr clanip bar (Fig. if). which latter is piv .oted in upright brackets 3l mounted upon the end ot the bed plate and provided at one end with the hand lever 32, sti that it can .he swuiig into or out of engagementwith the tubesA The clamp ha along its active ,edge

is ,provided with teeth or serrations 33 (see Figs. S andst) which are adapted to enter and fit thespaees or depression between adjacent tubes, so that. when -the clamp bar Yissivung' over from the dotted line position shown in Fig. S) to the full line position there shown, the' teeth enter between the tubes and clamp' the tube. t' 'ame in alinement with the'needles. The rear corners ot' theteeth, or those which tirst engagethe tubes, are preiferablvY beveled or otherwise shaped so that theyv act as wedges and, enterin;r between the tubes, wedge the tube Lt'rame laterally into the required alinement with the needles if the former happens to be slightly oti'set to one side or the other of the required position. By this means the tube` traine is not only held clamped, but is automat'icallyl broughtwith certainty into the required aline'ment.

Referring now to the means tor mstalling and holding the spool and the wound-on' yarn strands in the machine. the latter is provided with holders or boxes 2li depending* from the bed plate, in which holders the ends or heads ot' the spool are placed. After the spool inserted itis locked at each holder against' turningr in the holder or withdrawal therefrom by means of a locliing dogg or shoe 35 pivoted thereon.- To control the locking dogs simultaneous@r t'orthel locking or release of the spool, each dogV is provided with a pin 3G which projects up through a slot 37 (see Fig'. l!) in the transverse locking bar BS. The bar extends across the machine terminating' in a portion 59, bent as shown in File. i or otherwise suitably toi-ined, to permit the operator tto grasp and move thel same. YThe holdin;Y brackets or hangers Bt are, transversely slotted to slidably'support the bar, the latter being held in such slots by the angle clips llt).

The slots 37 in the locking har which receive the pins on the lockingF dogs are so inelinedV that, as` thevbar is slid transversely the machine. the locking;r dogs are .swungr up or downi the latter position being represented in l"i;.9. When swung up` the dogs permit the intrraluction or withdrawal ot' the spool heads trom the holders. hut when swung down. assume the position shown in Figi. "J where they reach out along the edges thereot to a sullicient `extent to retain the spool in the holder. s shown in Fig, Uthe contactinglr edges ot' the dogs are provided with teeth il which are adapted to grip the wooden ledges ot the spool head. there being provided a springr t2. in each holder which tends to throw the spool out against the dog. The teeth are so shaped that the;y

oppose the nnwinding movement 'ot' 'the thus readiliY t'ree the spool'to unwind it. or

can turn the spool while locked in the holder to wind up the yarn. it will he observed that it is securelyv loclted against turningT due to an)Y pull -received along; the line of draftot the tree ends ot' the nvarn. a'tter the latter has been led upvardl'v into the machine.

Having locked thc spool in the holder the operator disconnects the comb from the spool. and after pressing back the spool in the holder jto` release it and unwind .a sutlicient length of yarn, he place-s the'coxnb in a Lrooved comb holdert3 located in front ot' and at a level just above. the tube traine, the .varn strani'ls there'tor assuming the position shown bv dotted lines in. Fig'. 9.

1.13 and o.. 'die needles it; ot: which there isV 'one toi-each tube .a`re 'carried upon a suitzahlrtrosshead or'holder 4 5 at the rear of tlieinachine an'd are'so arinnged that, at the propertime. they, may be projected torwaidl v each thro/ruiltl one of thel tubes to seize a yarn strand or strands and draw the same A/tl'irougi ,its tube from the larger to the smaller eudtl'iercot'. The needle cross-head t3. asshown in Figs. l and 3, is tixedlv secured at each end to a slide bar 46, the latter adapted to slide through bearings or `iiiilc\\';r\'s. one otl which, t?, is supported at. the rear ot the 'frame piece 'l2-t and the other ot' which` 4S, is suspended Jfrom the bed plate 25..

To advance or retract the needles, the lower 4edge of each slide bar etti is provided with rack teeth t!) which mesh with gears 50,

the latter secured to the main operating: shatt The. shaft 5l is turned (see Figs.l l, 2. l and 4) by means of pinions 52 secured one at each end thereof` and meshing with a gear segment 53,.the latter carried back by a lever arm 54 pivoted at to the lst) frame. The two levers 54 at opposite sides vof the machine are connected by the transvhooks to be seized by the latter on their return. ln the presentembodiment of our invention this is accomplished by shifting the transfer comb itself. this acting, because of the close relation which thetransfer comb bears to the. needles and tubes to lay the varn strands with certainty. across the yneedles and within the hooked portions thereof, as represented in Fig. 7. Preferably the shifting operation is performed imwhanieally and imniediately following and consequent upon the assumption by the needles of their extreme advanced position. asshown in Fig. (3. '.lo this end the holder alii of the transfer comb is provided at opposite ends with slotted extension portions 57 and 5S, which are slidably supported between ears formed by projections of the supporting brackets 31. The bracket ears are provided with fixed pinsl 59 which engage the slots in the holder and permit a limited sliding movement of the latter with its attached comb. The projecting end of the holder portion '57 (Figs. l, 2 and 7) is provided with an upright lug (3U-which is secured thereto by means of a stud (3l passing through a slot (S2 in the holder so as to permit slight longitudinal adjustment of the lingr thereon. The lug is provided with a rearwardly projecting pin G3 which is engaged by the forked end of the upright arm (3lof a bell-crank lever which is pivoted upon the stud (55 secured to the bed plate 25.

The other arm 66 of the bell-crank carries a 'small roll G7 which is normally pressed inward against the slide bar through the' medium of a spring 68 encircling the stud' 65 and having one end secured te the lever arm 6l and the other to the stud. W hen thus positioned, with the roll bearing against the slide bar the comb is held as represented in Fig. 2 maintaining the yarn strands in vertical lines. Immediately back of the roll the slide bar is provided' with a cam member 69 having preferably a conical or wedge-shaped nose succeeded by a. circumferentially grooved portion so shaped as to form a seat for the roll. The cam member is loosely mounted on the slide bar so that, on advancement of the needles, it remains fixed wherein their relatively to the roll until the needles approach their eXtreme forward position. The cam member the'n becomes engaged. by a pin 70, or other suitable abutn1ent,.f.ixed onthe slide member and this causes the advancement of the latterfrom the position shown in Fig. 3 to the position shown in Fig. 6. The ad 'ance of the cam lifts the roll upon its conical nose and leaves it seated in the groove (it). Such movement swings the bellcrank about its pivot shifting the holder and the comb from the' position shown in Fig. 3 to that shown in Fig. 7.

The needles having been projected through the tubes and beyond the yarn strands by movement of the operating bar 5G to the extreme upper position, the operator then swings the bar down, causing the needles each to retract and seize the yarn or yarns laid across its shank and draw them through the appropriate tube. The return shifting movement of the comb, however, is preferably delayed until the needle hooks havel drawn the yarns into the tubes, such return movement herein'not taking place until the close of the, needle return movement. Here- .in the return of the comb and its holder to its initial position is effected by means of the abutment 71, shown in the form of a' 'asher secured to the forward end of the slide bar 46, which abutment engages the cam (39 and draws it back'to its initial position, thereby releasing the roll and the bellcrank, the pressure of the roll against the cam having acted meanwhile to hold the cam fixed notwithstanding the movement of the slide rod. v

In the practical employment of these machines it is preferable that the needles not only be guided close to the tubes prior to entering the same, but that their hooked ends be rigidly spaced when out of use and retracted. Furthermore it isalso desirable to provide guidance for the ends of the needles projecting through the tubes and before seizure of the yarn, otherwise the tubes which through misuse are apt to become bent and out' of alinement, are likely to throw some'of the needles to one side or the other lof the desired position. y

'Herein we have provided guidance for the needles close to the mouths of the tubes Where they enter, the guiding means being capable of retraction with the needles to permit the introduction of suitable yarn shearing or trimming devices between the tubes and the needles, and such guiding means `hcrein also holds in rigid separation the l. Such guide bar is secured at its ends to supporting rods 73, ythe latter slidably izo bar

" more@ 'thereby drawn 'forwardto brine the guide bar close to the needle points when tbe latter ere retracted. The forv'vard movementof the bar is limited by means of a pin 'in each rod, ivhiehpin abuts aga-inst the cross; bar or holder.

1When the needles are advanced the guide '72 is advanced with them until the needle hooks are close to the months of the tubes 'when the guide bar is brngbt to rest,

by abutting against a fixed part of the machine, herein the vertically fixed Knife or the shearing mechanism to be later described (see Fig. 6). The needles continue their ad- Vance through the tubes', v merely stretching the oonneeting'springs 74, the guide bar being subsequently returned with the needles to the position shown in Fig. 3 after the latter emerge from the tubes with the engaged yarn strands.-'

The needles are secured to the cross-bar between suitable spacing members by means of a key rod 77 of circular cross-section seated hal)c in each needle and half in e' plate 78 bolted to the top or" the cross-bar. To provide guidance for the needles on the opposite side of the tubes, means are provided whereby the needles, as they emerge from the tubes and before engaging the tuft yarns. are directed into ythe proper course )my suitable means may be employedfor.

this purpose and, it' desired, such guiding means may be carried and presented by the swinging; rlainp bai-.30, but .herein tliere is provided an additional member eornprisinga needle guide bar l extending aei'oss niarhine and adapted to'be swung down di-l rectly back oi llularge ends' off.' tbe ftnbes' 'and in the path of tbe needles as they emerge therefrom.y Such needle guide (Figs. 2, 8' and El) isrurrieil at each end upon arms pivoted in the brackets 3h near' the end of the bed plate and is provided at one end with a depending,Y lever arm 32 by means of whirh the guide bar can be swung fromthe Afull (line position shown in. 9 to the dotted line or active position.

rlhe edge of 'the needle guide is' provided with teeth 83 (Fig. 8) which are edaptedt swine; down in between the needles and, esv

' the latter emerge from tbe tubes, Wedge such as are' out ot' alinement into the required :ilinemenh Herein the needle rinde 1s depressed by meehanlcal means and properly timed with relation Vto the needle adyance.

For this purpose the arm 82, normally drawn back by the spring' 84, Whichi has its' opposite end secured to the bed plate to hold the needle guide up, isl thrown for-Werd to swing' 'the needle guide down, as described, by means of a pin S5, or other suitable. part;

ixerlly secured to the slide-rod 46. This pin engages the lever 82 and swings the needle guide down. This `preferably takes 'fplaee justfasthe needles emerge `from the tnbeegaand the lever is provided with an inclined end which .rides upon the pin as the needles continue'o advance, so that 'the needle guide, when swung downJ is held there until the needles have seized the yarn strands anddrawn them back into the tubes, whereupon, the pin 85 moves back and allows the lever 82 to drop. The lever arm is shown as engaged by the pin 85,111 the' vdotted line position shown in Fig. 9.

Prior to use in the loom it is neoessary to out the drawn-in yarn strands evenly at a Lined predetermined distance .from the ends l,

of the tubes. Herein .we have provided shearing means whereby this is automatically accomplished in 'the same operation'v with tbe tubingf of the yarns. To this end there is provided vdie vertically iixeeljrniie 76, already referred to which, however., is supported at the rear edge of 'the bed plate so as to be capable of e. slight yielding movement toward the plate. secure this, the knife is supported on stnds'fi (Fig. 10) each slidably mounted in a pocket in the bed plate and provided with an upright pin 87' working in' o small transverse slot 88 in the plate. Relatively 'still' springs 89 areseated at intervals in the bed plate and bear against the knife to force the latter bark and the. pins 87 to the rearward limit of the slots 88. The threadsr of the yarn strands when drawn boel; by the needles, lie directly over .the upper edge ofthe knife 76 and in that position are cut ed" bya' downward movement of tbe vertically movable knife 9G. The-latter has an inelined'edge, as shown in l dotted outline in Fig. 2 andat its extreme le 't hand end, aeyiewed inl Fig. 2, which. end, when depressedy irs'trneets the fixed finire blade, it is connected to a cem mein ber 30X leaving a lower beveled edge as shown at 9i in Fig. 6. The blades are so arranged tbet tbe vertically movable blade'SO, when eieveted, lies somewhat over the stationary 'fixed blade, and when depressed,v acts first through eine com member 9G* and subsequently through the blade member 90 itself to wedge the blade 76 forward against the ILOG @fielding springs 8 9. Thus, as each sueceed l fing portion or' the bladeedges cross, the shearing;I action is accomplished by a press ing beek of tbe'stationary fixed blade, 4thus givingin efi'ect the action ot' a pair of shears and imparting a clean shearing cutjto thel yarn. Y i, To impart suitable and approiriately timed movement to the vertical Inovableblade, the latter is bolted to the transverse' supporting beam 92 which, in turn; is lixedly secured at each end to) vertiea lly reciprocable plunger rods 93, the latte? ftfuided for sliding movement in opper and lower brackets 94 and 95 attached at the traine, member 24. Une side of eaeh plunger rod 93 is toothed vto form a rat-k 9U, and this engages in earh -ease with a pinion 9T, the latter seeured to the shaft 5l whieh earries the main driving gear 5; and the needle operating gear 39. 'i`he parts are so geared that, as the needles are retraeted out of the path of the shearing nieelianisni. the latter deseends from the position shown in Fig. ti to that shown in Figs. 3 and 9, and trims the ends of the drawn yarns. hand, when the needles are advanced. the

upper blade member is lifted up and out ot" their path.

In praetiee it is quitenecessary that the projeeting ends of the drawn-in varns should be triimiied evenly and with eertainty to the required distanee from the ends of the tubes. ln order that the tube frame. when withdrawn from the maehine. may have the varn strands eut the required length and -may also be held fixed in this relation on the spool. thus being ready for theloom with-- outy the need of any further step or operation. means are preferably provided so that, after shearing. and preferably when slieai'ed the endsof the yarn strands are held elaniped andthe tubeframe is also held elamped.

'lhis permits the operator to remove the spool from its holder. wind up the slaeli varn thereon and apply the spool to the tube frame by inserting pintles 2L thereof in the end springs 9S. 'lhe latter are eustoiuarilv provided on the tube frame and. wheu-the latter is installed in the. maehine. project outwardly from the maehine as shown in -Figs Zi and (i. 'lhe spool then oeeupies the position shown in dotted lilies in Fig. 9 and the tube fi'ame. spool and yarn ends being'.

definitely and tixedly positioned each relatively to the other'` the tube franie, and yarn ends may be released and withdrawn from the maehiue for use in the loom without turther attention. To this end we have provided elaniping or holding means for elaniping they yarn strands between the small ends of the tubes and the knife. Such clamping means may be embodied in various forms, but herein we have piovided a holding bar 99 exteiu'ling across the machine and 0&1'

'riedby the shearing mechanism so that,

when the needles are advaneed, such bar is elevated with the knife 90. out of the way, as shown in Fig. (3. hen the needles are retraeted, however, and the shearing blade descends, the holding bai' is brought down across the drawn-in yarn ends clamping them' tight against tli'e flat topof the bed plate 25', as shown in Fig. 9.

Preferably,y though not necessarily, 'the holding bar engages with the yarns just prior to the shearing operatiom so that, before being cut, the yarns are g'ipped tight over the bed plateand relatively near the ()n the other .baia and 'aeting to depress the holding bar to its lowermost position -(Fig. (i). Its downward movement is. limited by an abutment. sueh as the eollar I1025 carried by eachv pin. whieh abutment eontaets with the upper side of the beam supporting arin 191. (in the depression of the shearing blade the holder bar elamps the drawn-in yarns ]ust prior to the shearing eut.y subsequent depression of the blade resulting merely in rompressmg more or less the springs 192. l`he holder bar may be of any suitable material and of any desired shape but herein isA formed of la metal strip or' plate with a lower rounded or beveled edge;

ln order-that the varns may be, released from the holder bar for the witlidra 'al of the spool and tube frame fioin the machine, as deseribed. while still leaving the needles retraeted and the shearing blade depressed (in whieh position it will benoted the parts i are rwdy for the drawing-in of the neXt set vided'with a forwardly directed finger 104 whiehjtsee Fig. 9) overlies` the clamp bar.` it() so that, when the latter is swung up by its handle 3;. the bar engages the. two fingers lll-i and lifts the holder bai-- 99 against the eompression springs 102 so that the yarn ends are free to be withdrawn from the miv ehine with the spool and tube franie. The elevated position of the holder bar and fingers will be elear from the dotted line shown in Fig. 9. The operator, therefore, having drawn in and trimmed the yarn strands, releases the spool by movement. of the releasing bar 43. winds up the slaclton the spool and fastens the latter to the tube frame springs 98, as described, the yarns mean- Movement ofthe handle 32 thereupon serves restoringI For this purpose each to release both the tube frame and the yarns ing"r machine with the connected yarn strands.'

K means of the upright positioning pin lol;

shown at the lett-hand end of the bed plate7 as viewed in Fig. 2. corresponding pin might be employed for the opposite end of the tul rame, butpreferably one end only is'po's oned so that the operator will place the tube frame in' the machine with refer ence to the pin 106, allowing the alinement clamp 30, when subsequently applied, to en-r force, if needed, a delinite alineinent with the needles.

It will thus be seen that the yarn transfer comb is definitely and predeterminately related first to the reed pins in the windingY machine and later to"th'e.ncedles and tubes in the tubing machine so that the yarns are received from the bobbins, then transferred and later presented to the needles for the tubing operation by the same instrumentality, c. the transfer comb. Large num-- bers of transfer combs may be employed in practice of standard dimensions so that, not" only may the same comb be repeatedly ap plied to the winding machine, with assurance that the teeth will exactly aline with .the reed pinsT or to the tubing machine with assurance that the teeth willexactly aline with the needles and tubes, but successive standard combsA may he used in each machine 'with certainty that the yarns held hy one clamp will hear exactly the same relation to the reed pins, needles and tubes asthe yarns held by another clamp where the same pattern has been used'in each case. rlhis not only provides effectually fot-'the transference of the yarn strands from 'one machine to the other and for the tubing of the yarns l *with the minimum chances of disarrangev :the operator.

ment inthe intendedpattern, lout by the use of a single standard instrument of transferpinsL great rapidity of operation is secured with a minimum of attention on. the part of .The provision also for the efl'ectual guidance of the needle both in en.- tering and'emerging from opposite ends of the tubes practically enforces and' insures the drawing in every instance of the intended pattern.
