This invention relates to machines for plac- 111g expansible spht rings on bobbins, part1c- 'ula'rly those of the type used inautomatic,

looms.

Such bobbins are generally made with a head around which are. two or more shallow grooves in each of which rests a split ring.

' uch, rings are ordinarily made ofispringy metal and are expanded so that they can: be.

forced over thela-rgo end or the head of the bobbin into one of the grooves. It is desir able that the splits in the rings should not be in the same line, and it is desirable'that they should be evenly arranged around the circumference of a. bobbin head so that the 'jawszin the receiving shuttle can hold the LZO ' e N e are also aware tion, and that the ring is carried toa certain bobbin in the correct position with its axis coinciding with the axis of the shuttle.

We are aware that there aremachines for placing-these'rings on the bobbin andthat afterwards the rings are turned by hand into the correct position, and we are aware that.

there are machines for turning the rings by frictionto a certain predetermined point and a then forcing one ring on the bobbin after which the bobbin with one ring is turned, then forcing another ring on the bobbin and again turning, and so on.

that there are machines split of each ring will be in the same po'si bobbin and forced thereon after which the bobbin is automatically turned perhaps onethird when another carrier with-another ring having its split in the same position as the first is forced on to the bobbin, after which the bobbin is again-turned and another carrier with another'ring also with the split in the same position is forced on the bobbin.

With this invention, we feed one rin'gat a time preferably by automatic machinery and drop a ring on to what We will call a floating cone which is a cone so held that a ring can pass over thetop, and out at the bottom on to a bobbin which is held up underneathit.

' On this cone is a revoluble sleeve of a size to catch and holdaringdropped over the top of the cone orforced down on it by an frame is at the top.

expanding stroke of aplun'ger carrying suitablefingersor jaws. 1

Around this sleeve is a positively revoluble ring gear with a pawl on the inside adapted to catch the splitin thering,,such gearpreferablybeing operated to revolve one andone- This particular bobbin with a one ring placed is then carried to a next station where the same process is repeated. for the next ring, the difference being that the pawl and the split will stop at anoth r position,preferably one-third of the circumference away from the first split.

Thebobbin is then inoved to a third station,

if three rings are required, and the'processis repeated. r I

All of theactions belng positive, there is no chance for any of the rings to get out of place, and with any suitable automatic feed-' ing device to feed one ring'at a time to each suspended cone, all the operator needs to dois to placeeach bobbin in its carrier, after which it is carried along from one station to thenextand finally discharged any suitable automatic mechanism. As" all three stations are operating at the same time, it

ineansthat a finished bobbin with three rings is being discharged at every complete cycle i and the machine is therefore very fast.

, Besides this, if the operator fails to feeda' bobbinv to a particular carrier, no vharm is done except that three rings are dropped on the grou'nd, but it is not necessary towait or to start over again to get" the correct sequence of operations in placing thedifl'erent rings.

vWhile we prefer the suspended cone'construction inwhich a cone is supported by three wheels each of which has radialslo-ts and each of which revolves in a curved, Slotin run the cone, the principle of the machine can be used with what is known as a rod feed. In a rod feed, a large number of rings are loaded on a rod at the end of which a cone is carried, such feed being preferably provided with some automatic device which will feed one ring at a time to each cone.

We prefer to use three ring setting stations each having a positive ring turning device which will position the ring at a point 120 degrees from each of the others, and also an automatic feed which will feed one ring at a time to each of the three stations, together with carrier mechanism to carry a bobbin from one station to the next as with this construction the operator has only to-feed one bobbin at a time to one station. 7

The main idea isto position and turn the rings with their openings at predetermined co-relative angles, before they are applied on the bobbins and to prevent displacement of the ring openings between the time they are correctly positioned and set on the bobbins.

The second consideration is to do this work 7 with expedition combined with accuracy.

Turning the rings to predetermined positions before they are placed on the bobbins and then dropping them on the ring guides for transfer to the bobbins results in a great deal of displacement of the openings as regards their co-relative positions.

Turning the ring openings to a fixed position and turning the bobbin by hand after each ring is applied is inaccurate, unsatisfactory and slow.

Turning the ring openings to proper position after they are placed on the bobbin, tears the grooves in the bobbins and causes much defective work.

ihe action of this machine turns each ring opening accurately to a predetermined position, stops the ring and looks it firmly until it is set on the bobbin.

To accomplish this result five difierent unit organisms are employed, either as units or in corresponding pluralities.

Since the apparatus herein described is designed to apply three rings to each bobbin, three similar organisms of each kind are used at each of three ring placing stations. These include: v

' Three ring feeds with positive let-off motion.

Three floating cone ring guides, each preferab y supported by rigid sustaining wheels, each revoluble in a groove 1n the cone.

f Three plungers, each with a driving head carrying three similar sets of ring setting jaws and each with synchronized intermittent reciprocating motion.

'Three revoluble ring carriersleeves, one revoluble on each cone. 7

Three pawl carrying gears, each carrying a pawl.

split in the Three or more bobbin carriers so arranged as to permit placing a bobbin in a carrier, which is then intermittently moved from one ring placing station to the next, one ring being put in place at each station.

The number of ring feeds, floating ring guides, sustaining wheels per cone guide, plungcrs, driving heads, ring setting aws per driving head, revol'uble sleeves, and pawl carrying gears,are all co -related to the number of rings to be applied to each bobbin and to the degree of angle between each positioned ring opening. We mean by this that when three rings are to'be applied, as in'the present case, three corresponding ring feeding, ring turning and positioning organisms are employed and if two or four rings were to be applied, an organism of each kind would be omitted or added, as the case required and the degree of angle between ring openings changed by appropriate gearing ar rangement.

The bobbin carriers indicated by H, H travel from left to right andfc- :rry a'bobbin from station D to A then to B, then to C and along to E where it is discharged. Each bobbin stops at each station long enough to receive a ring,

If more or less rings than three are to be set, more or less stations are used and there are certain other changes which are desirable and which can be made.

As'sh-own in Fig. 1, the fixed frame of the machine indicated generally by M includes a base 1, a cap 2 supported by three columns 3, l and 5, a hollow central column 6 which serves as a pivot for a sleeve 36 and for other parts, and. also a plate 41 which supports other parts of the mechanism. V

A plate ll fastened to colums 3, 4, 5' bu't loose on sleeve 36, carries the ring feeding;

The ring feeding mechanism consists of the following parts, as see Figs.- 1,2 and 4.

discharging TIOlIlilQ'fl'i to three orifices large enough for the size of ring used to drop through easily, and located directly over the intakes of the three feeding organisms in units a: and C i r v Housings 52 in units A, B and C each have a radial groove 1-50 in vwhich fits a fiat slide 50 slightly thicker than a ring, located in each housing, and retained by slotted cover plates. 53;. These cover plates each have an opening 223 large enough for, the sizeof ring used to enter freely; these openings 223 are directly under and connected by vertical feed tubes 55. of equal inside diameter, with the three orifices 123 in chute 23,, so that the ringscan drop through the chute orifices 123, to thetopof each slide 50. 7 ,7 V The size of orifice used in the chute. 23. is such that a ring. too large will not enter but ,will pass'by the orifice and also if two,- or

more rings become locked together as is often the case,-th-ey will not enter the orifice but will pass by. v r,

Each tube 55 contains a free hollow light cylindricalfloatingpost 56"resting loosely on slide 50 with its base rounded to a point slightly; higher than the thickness of aring. The tops of hese p'ostsare conical with their apices placed slightly'below the bottom of V chute 23. Y I V I The rings fill tube 55' in unit C,- then fill tube 55 in unitB and then tube 55in unit A. Thereafter all tubes are kept full and the surplus returns to hopper 22 along the chute shown-in dotted lines in Fig. 1. a

IThese posts 56 are of such diameter that the size of ring used will pass over samefreelybut a. isi-zesmaller ring-will not pass overand the combination of the sized hole in chute the ring drops 23 and the diameter of post 56 constitute an automatic check against clogging or ammingof the machine.

The main funct1on of this floating post 56 is for its conical point to enter the ring through the'orifice 123 in chute 23 and so that the rings will always lie in a horizontal position within the tube. This is very important, as if the ring entered thetube and remained in an inclined or vertical position, the feed would jam and something would break.

As the slide recedes, the post 56 and tiers or rings rest 011 the slide, but when the slide 50 has fully receded, the post 56 and rings drop down, the lower ring coming in front of the face of the slide 50. The slide 50 then advances and comes incontact with the bottom ring and pushes it ahead; As the ring advances, it forces the rounded bottom of post 56 upward until the ring escapes from around the post. and the slide passes under the post, the slide continues to advance until the ring drops through a cone hole 152 in groove 150 and is deposited on the sleeve 81 of floating cone 80 and then returns for another ring, the post 56 and bottom ring rid ing on the slide until the slide recedes to its full stroke then permitting the post and another ring to drop for a repetition of the process. 3

. The motionof the post dropping and rising agitates the rings and keeps them settled close together horizontally.

' The three slides 50, 50, 50 are reciprocated together by cam 46.

As shown in Fig. 3A, the belt 21, and chute 23 may be omitted and rings can be fed by hand on to one or more floating posts such as 56.

y The ring placing statz'0ns.At each station A, B and C is a floating cone ring guide which includes a vertical cylindrical post 80 having a truncated conical cap 82 the lower part of which is slightly larger in diameter than the base or butt of the bobbin 86 on which the rings are to be applied. 1

This post 80 is supported rigidly as a floating member by a series of three sustaining wheels 83, 88, 83, fitting freely in-three vertical segmental grooves 183, 183,183 in the post 80. See Figs. 6 and 7.

The three wheels 83, 83, 83 which sustain each post 80 are disposed radially at angles of 120 degrees with each other and'revolve on studs supported in the lower half of each housing 62. Each wheel 83 has a plurality, preferablyffour, escapement slots 283, 283, 283, 283 each to permit the downward passage of a ring Z over the cone ring. guide post 80 on to a bobbin 86. Located on the hub of each wheel 83, is a corresponding number of curved depressions 87, 87, 87, 87.

In positionto engage each depression as it I sleeve 81.

comes around is a brake formed by a checking ball 88 compressed by a spring 89. This The slots 283, 283, 283 in the escapement wheels 83 are of sucl size' and such number and so held in place by the action of the checking ball 88 on the hub that the top slots 283, 283, 283 of all three wheels 83, 83, 83 are always open for the downward ingress of ring and are so disposed that upon egress of the ring, the next set of slots attop'of all three wheels are in position for the ingress of the next ring.

A minimum of slots in wheel is preferable, so as to leave as much bearing surface as possible between the wheels and the curved grooves 183, 183, 183 in the posts 80, and also for strength in the wheels. These slots must be of sufficient radial depth to allow a ring to slip down along a post 80 without jamming.

Each ring guide post 80 has a cylindrical stem surmounted by a conical cap 82 which so each GSC apement holds a revoluble sleeve 81 that it can turn freely on a vertical axis. 7 i

This sleeve may be tapered at the top, as shown in Fig. 6, or the cap alone may be tapered and the from top to bottom on the outside without a shoulder or with a shoulder as shown in Fig. 13.

The ring setting mechanism includes at each station a plunger 17 with driving head 5'? carrying'a series of yielding spring jaws 58 corresponding in number to the number of sustaining wheels 83 for each ring guide post 80 which is disposed axially above each ring guide post 80. The jaws are concaved on their inside to fit the outside of a ring guide post 80, but they are separated sufficiently to permit them to pass down the ring guide 80 between the retaining wheels 83 without coming in contact with the latter.

The plunger travels from its extreme upward position where the bottom ends of jaws a ring to be fed by the slide 50 over the cap 82 then down so;that the jaws forcea ring,

over the conical cap 82 on to the revoluble The jaws then move up to a point which clears the top of gear 63 and the path of the pawl 63A, at which point it dwells during that part of the cycle required for the pawl 63A in each gear 63 to rotate and turn the ring opening to its predetermined position. The plunger and its jaws then descend the remainder of their traverse and force the ring along and off thering guide on to the base of bobbin 86. Each plunger and its jaws then ascend to topposition to permit another ring to be depositedv on a cap 82 and the process is repeated. 'The revoluble expandersleeve 81 has the.

sleeve may be cylindrical top portion so tapered-that when a ring which is larger than the base of cap 82 is dropped on, it will settle evenly on the conical part in a horizontal position and not hang at an angle. This is necessary to allow simultaneous contact of the ring Z with all three jaws 5S, 58. V

'Theilower portion of the sleeve is straight and of a diameter sufficiently in excess of the iameter of the ring expand the ring when the is forced down onto and along this straight section by setting jaws 58, If this sleeve 81 was stationary instead of revolulole, or if it were omitted and the rings turned aroundthe solid cone, the friction between the ring and the stationary sleeve or solid cone, as the case might he would be'so great that the pawl 63A would slip out of the opening in the ring due tothe tapered ends of the ring and -fail to'inovethe ring opening to the desired position, and the machine would not be positive.

Preferahlyeach should be expanded by being forced over a conical cap like 82 or 382, or else over 'the conical portion-oi a conical sleeve, or over both, so that the ring Wlll hug the sleeve and turn it when "acted "on by a turning pawL.

Moreover, as the pawls 63A revolve at very high speed to attain a production basis they would slip if any'great resistance was encountered. V.

Even though a pawl could be made to hold against the tapered end of the ring, the triotion between the-ring and stationary-sleeve or cone, as the case might be and'the power requlred would be so great that the bur'red' ends of the rings would quickly wear away the with an opening throughits centre large hardest steel cone and also the pawls. Moreover, the springtension" required to make a pawl resist slipping from the tapered end'ot the ring would be so great as to cause the pawl to turn the ring by friction alone, beo're the pawleiigaged the opening in the ring and "again for this reason the action would not be positive.

ltis therefore imperative that" the sleeve -81revolve freely. V

The ring turning pawl and gears consist of three equalhollow gears 63, 63,- 68, each enough for the jaws 58 to pass through.

{lhese three gears engage with a common gear 76,which' is one third larger in diameter so that at every turn of the gear 76 the three pawl hearing gears 63 revolve one andonethird turns. Each of these ears'issu orted --by the exterior of its hub 163 in bearings in- Eachgear has a pawl 63A dishousings 62.

posed at an angle of 120 degrees withthe pawl on each'other gear, as, the rings are turned; in other words, "it the three'gears' .were placed one above anotherin coinc dence 83 in each unit Z, to partially permit a ring each pawl would degrees from each other. a See Figs;6, 7 and 8.

The :pawls are so arranged that each stops i r directly over the top of an escapeinent wheel mains locked in that position while the plungerforces the ring frorn'sleeve 81 downcaperne'nt wheels, the j aws 58-never touch the a pa-wls. This feature eliminates wear .ofthe pawls as the plunger aws w1th thelr sharp edges 'would'qulckly wear out the pawls.

Three pals 63A,- 6 3A, 63A,one in-e'ach gear 63 are arranged to swing on a stud at such an angle as to tend to cause their free ends to dig into the revoluhle sleeveh81; words, they tend to push rather than drag.

Each pawl is heldfin light compressionagainst the sleeves 811by a spring 153A, That in other portion of the pawl which comes incontact with the sleeve 81 is straight at the contact surface.

Above "the straight contact surface 153B,'the pawl is inclined at 153C, to

to easily torc'ethe pawl away from thesleeve while the ring is being 'pusli'ed f downihy the plunger jaws'58 duringgtheir initial downwa'rd stroke. Theroun'cl ring is the only surface which" ever comes in; con-- tact with the pawl and as the ring operates on'the inclined top of the pawl, thejstrainand wear on the pawl is therefore reducedto' a minimum, I i.

It is found convenient to make all three plungers so that they will be operatedby a single cam 14," the' 'only 'diiierenc'e in the I plungers' beingithe 'length 'of their jaws 58. This flength corresponds with the distance 'etween' the rings 'on'thefboboin. It is therelocate their respective I rings 1 in engagement with thepawh v ln'Fig. 13, I sho w a 3'80' on whichis revolulole asleeve 381, The nose 382is preferably taperedandfholds sleeve 381 in place.

- The pawl shown is a piece of, spring wire 386 fastened at one end inside ring gear 363,

and thence extends over so that it normally enters the recess 383 andthence extends up and out. This wire can be made so light that a ring dropped over the nose 382 will force the wire 386 out andarest on the swell 383, but when gear 363 revolves with wire 386, the latter acts like the pawl and when it strikes thesplit in a ring Z, it enters just enough to carry the ring and sleeve, or the ring alone,'along with it until it stops. It

should stop at a placebet-ween the jaws 358' so that they will not strike it as they descend.

Atleast one full turn of the gear 63 and pawl'63A' is required to positively engage the opening of the ring, and more than one turn is desirable to positively assure engagement. Moreover the pawl must stop over an escapenient wheel 83fto escape contactwith the jawsas they come down; therefore, one and one-third revolutions of the pawl gear is the minimum of rotation which will positively effect pawl engagement and still stop a pawl over anescapement wheel 83, if they are disposed 120 degrees apart. This is aco'-relative feature above .referred to and is the armittent withaQO degree dwell.

If four rings were used for instance, the

- olution in one-third of the drive shaft cycle and remains at rest the other two-thirds. The lower member of compound gear 75 is equal with and engages gear 76, which in turn engages ring turning gears 63, 63, 63.

Now, male intermittent drivegear' 74 is three times largeas-"its female engaging member of member of compound gear 75 is equal in diameter to gear 76, and gear'ZG is one and one-third times as large as gears 63, '63, 63. The result is that at each turn of drive shaft 11, gear 76 malzes'one turn and remains locked stationary the equal of two turns.

One reyolution ofdriveshaft 11 constitutes a complete cycle of the machine.

It follows that at each turn of vertical drive shaft 11, theEring turning gears 63, 63,1

63 revolve one and one-third'turns in onethird of the cycle and "remain locked at rest the other two-thirds of the cycle.

This arrangement permits the ring turning function to take place in meander the Y cycle and the feeding and setting of rings to each ring Z "over the swell such as' 56.

100 .is the high point of the plunger ,or plungers and when it moves down to 110', it forces the ring Z down sition on sleeve 81. There is then a slight retraction to 120 so that the jaws will not interfere with the turning pawl in turning the ring Z. This turning is accomplished at thedwell between 120 and 130 and when ac complished, the jaws 58 move down as to 150, forcing the ring over the floating cone on to the bobbin.

here a set of three plungers is used and a bobbin moves from one to the next, the various positions 100,110, 120 and 150 will be correspondingly higher or lower, according as the top or bottom ring is being positioned.

It maybe desirable in some cases to omit the, ring turning-device which can readily be done by removing thepawls or wedging them .out of-a ctlon and our machine with the automatic feed, floating cone and bobbin carrier is very effective and very fast, although it may be necessary after the rings areplaced to turn them by hand or in some other machine.

It is obvious that we can use other automatic ring feeding devices such as the drop pingdevice shown in patent to Hodgman, and other, 870,960, November 12,1907.

It is also'obvious that instead of a chute having three openings we could :asv readily use three chutes each with one opening or other device forllanding the rings on apost It is also obvious that a post 56 could be filledup with rings. by hand, and it is obvious that we might feed one ring at a time by hand. to each of the three floating cones one at each station. 1

lVe may alsoveither with or, without any automatic feed device use onlyone station with a ring turning device'as for instance one which'moves one and one-third turns, thereby making theopenlng in each succeeding ring 120 degreesbeyond that m te predecessor.
