ANKER PETERSEN, a sub`ect Aof the King ofDemnark, residin atv eston, in the county of Sulolk lan State of Massachusetts, havev invented new and usefui Improvements in' Machines for Making Tubular Fabric, of which the folllowing is a specification.

This inveutonrelates to improvement in rotary' braiding machines and the object of the lnvention is first to4 provide a rotary braidmg machine having means for introduein luto the fabric a h' 'er number of str-an s of one series than t ere are in the other, this object being attained by the use of a plurality of series of thread guides or thread directin members alternatmglwith each otherl an meansl to reciprocate said 'tion which upon the breaking of thread guidesof each of said series in a vdirection opposite to that of the other, these guides being `arranged in sets and the bobbin. carriers sup lying threads for the re. mainin series-c str-ands being carried' between-t e threads-leading from each set of thread guidescr thread directing members. in this way the fabric is built up several times as fast asin machines empioyin only a single series of thread guides or iread directing members corresponding' in num- 'ber to the individual spool or bcbbin carriers.

Another'objectfis to provide a sto moan read on the machine or upon the threaxi masses becoming exhausted, shall 'operate to stop the drivmgvmechanismcf ,the machine.

i do not herein claiin the novel features of the. spool carriers and their thread controlling devices, :but reserve them for the subject matter Aoi a separate application or applications..

The invention consists inthe neve? featurcs of' construction and the combination- `andarrangement of parts set. furth'n ,the .fo'lcwing -speci'cation and paticuiay pointed out in the claims.

Fig, 8 is a detail; sectional view taken on line 8'- of Fig. 7, looking toward the right. Fig. 9 is a 'detail plan, partly -in sectiumshowrn a modied form 'of spooi orb'obbin carier, Fig. 10 is a diagrammatic view illustrating the parts and wiringv of the ee'ctriestop motion.

Like numerals refer to like parte throughout the several views of the drawings. ln the drawings,` referring particularly to Figs. 3 and 4;, 115 is the frame of the ma- .chine 'havin mounted thereona hollow stationary sha thereon in suitable bearings a main iving 'shaft 17. On'the shaft 17 is a clutch 18 comprising a member 19 loose cn said shaft and a w secured to said shaft the former .being shifta'ble into and out ci engagement with .the latter by means of a clutch shifting lever2'1. The dutch meme dog QBis rewand havingalso sugported the frame 15. Also secured to the shaft 27 is .a se, .e

ur gear 28. meshing with a s ur gear lie iat-ter bei-ng secured" to a ictatable .body 30 journaled jon. a sleeve 31 and said sleeve 511 turn being iournaled. cn the hollow Stationary shaft i6.. worin 32 secured to the 4Shaft IT meshes with a worm gear 83 the glearing s' isA secured' tothe' sleeveA 3L By just describedx when the drivin aft y rotated' in the oper direction, t e gear 29 -is rotated inftii, .direction of the arrow al and thegear 33 in the direction ofthe arrow B, see Fig. 4.

Secured to the sleeve 31 is a body consisting of three parts, a wheel 34, a ring 35 and a ring 36 rigldlysecured to each other by a series of posts 37, lsee Figs. 1, 2 and 5. The wheel 34 and ring 35 areseparated bya circumferential space 38 in which is located a series of spool or bobbin carriers 39 each of which is provided with an upwardly extending flange 40 llocated'in si-groove 41 provided in the rlng 35 and a downwardly. extending flange 42 located in a similar -groove 43 provided in the wheel 34.' Eachl of these carriers has thereon: a spurgear segment- 44, the teeth of which project'toward .the out-` side ofthe machine. Carried by -the body 30 is aspur gear-45 with which a series of pinions 46 mesh, said pinions being, respectively, formed on or securedto a 'series yof vertical shafts 47, the upper ends of which are secured, respectively, to' a series of pin-l ions 48 arranged to mesh successively with the segmental geards 44. The shafts 47 are journaled at vtheir upper ends in the ring 35 and at their lowerends in the ring 36 so that a relative rotative :movement of the gear and the body consisting of the arts 34, 35 and 36 results in the two 'series o pinions 46 a'nd 48 being revolved about the axis of the gear 45 and being rotated about'the. axes of their respective shafts 47 thus revolving the gear segments 44, about the axis of the gear 45, it being understood that the shown, so as to have a yieldin frictional'em gagement with the bores of t eir respective I spools. On each of the spools 50 amass'oi 45 t read 51 is wound in any usual or desired manner and the thread 52'leading from the' purpose of this bem explamed herelnafter.

thread mass passes through an eye' 530i a rotating thread guide or slack controller 54 l' journaled concentric with the axis of the thread/I mass on a hollow thread guide 55 sevcured to a U- shaped :trame 56 carried by each' spool carrier 39. Adjacent to Vtheinner end of each thread guide v55 .is a second thread guideI 57 separated therefrom by a slight space, 4as shownin Figs. 2 and 7, the' It will be understoo th at the variousthreads 52 lead through the guides 55 and 57 to the i center of the machine, that is, to the braiding point. Asthe thread'isdrawn from each thread mass the tension thereon causes r the thread guide or slack 'controller 54 to be rotated by thethread as it unwindsrom the threa'd mass-in an obvious manner, it being understood that said slack vcontrollerported a ing mova le thread guidesror thread direct-- permits the Ithreadto' be drawn from the 'X thread mass without tangling and with the least amount' of resistance.

Supported on the ring 36 is a series lof posts 58 and on"each'of these posts is supair of levers 59 and'60 constituting members, the -levers'59 being the members of one series and the' leversl Qbeing the I members of a second series, which series 7`5 alternate with each other about the machine.

.To each lever 59 is pivotallyaconnectedja link 61: and to each` lever 60`is pivotallycon-' nected a corres ending link 62. AI series of circumferentia y arranged leversf. ivot allymounted substantia ly; midway o their length on the ring. 36 have journaledthereon, respectively, cam rolls 64 locat in the oove of a sinuous cam 65 carri d'by the body 30.' A seriesof Asimilar levers 66""10- cated at `a higherjlevel pivotally mounted on the ring 36 have mounted thereon, re-

spectively, camrolls 67 located in the groove of a sinuous cam 68 also carried by the rotary body 3 0.' Opposite ends, respectively, of each lever.63 are pivotally connected to links 61 and 62and the next sncceediriglinks 61 and 62-are` pivotally'connected to oppo- Vsite ends,re'spectively,of the next succeeding lever 66 and so on aroundthe machine,

the arrangement f being such that when a' relative rotation is imparted to the ring 36 and Athecams 65 and 6 8, .the two series of levers 59 and 60 are simultaneously reciprocated in opposite directions, that is, when one entire series 59 is lowered, the" entire series 60 is raised, as shown in Fig. 7, at

tween. As' the levers 59 and 60 are preferably exceedingly light and delicate 1n conseeFigs. 2, 5 and7, ment thereof.

preventing lateral move- -which time the spool carriers pass therebe- 1057 struction, 'I provide guides 69,'70and 71,- l

Secured to the 3.6is a series of brack i -ets' 72 located at intervals therearound, each of thesefbrackets constituting a support'for` Y* two spools or bobbins 73Qand74 journald,v I'- respectively, 'on npright'p'lnsl75 and. 76.

`From the mass lof,thread.'ori-(eachspool or bobbin 73, a thread 77 leads through'athread guide 7 8 having'a verticalslot 79 therein, said, f1.5.' i I guide and also 'thelpivot yof the levers 59".;-

Athreadguided by the thread guides 81.

thence across a pin 82 constituting athread guided and also the vpivot of the levers 59 and '60, said thread passing thence-.through an eye 83 provided :1n the movable thread Guide or. thread directing member 59 and.

leading therefrom to the braiding point at the lcenter of the machine. Similarly, a

the spool'or bobbin 74 passes through the through a thread guide 85, thence upwardly through a thread guide 86, thence across the slots 79 in the. thread guide' 78, thence' thread 84 leading from 4thethread mass on respectively bears .becomes diminished to a certain size, said arm will be rotated under the influence of its. controlling spring past the periphery of the thread mass. In Fig. 6, the arm 97A is shown as having moved under such conditions, thus carryin-g the arm 102 into-3v contact with the contact plate 88. v

Referring nowito Figs. 4 and 10, the pivoted latch 22' constitutes au armature adapted to cooperate withan electro-magnet 119, one end of the winding ofiwhich is connected by a wire 120 to the positive terminal of the battery 118 andthe other end of which is connected 'by a wire 121 'to a con# tact plate 122 against which the clutch shifting lever 21 normally rests, said lever being grounded on the frame of the machine. Normally, the stop motion circuit is open, but if through the breaking of one or more ofthe threads 77, oneor more of the yieldable thread guides 81 contact with their respective ,contactA plates-88 a `circuit is .com`

pleted hrough the Wires1'05,`106, contact plates 107, wires 108,114, plate 1.15, bushing `116-, wire 117, through the battery 118, wire 120, electro-magnet 119,. wire 121, conltact plate 122 and` clutch shifting lever- 21 to the ground, tht is, to the frame of the machine, thus ca sing the electro-magnet 119 to become energized. The energizing of the electro-magnet lifts the latch 22 thus releasing the dog 23 and allowing the clutch member 19 to be carried out of engagement with the clutch. member 20 under the influence of the spring 24. In like manner, if one or i more of the threads 811 should break, the

thread guide or guides 86 released thereby 'would yoperate to'-st0p the machine. Also since the arms 102 and 104 aregrounded upon the frame of the machine, it will be evident that if one :of the thread masses on ythe spools 73 and Tf1` should become `exhausted a circuit will also'be completed to tl1e.'electromagnct thus acting to -stop the machine.. vSo also if one of" the threads 52 should break, a circuit would be completed to t-he electro-magnet. If in any of thesecases the electro-magnet is energized and the clutch 'shifting leverl 21 is thereby released, said lever in passing out of contact with the plate 122 breaks the circuit at that point. j

In Fig. 9, I have -shown a modified form of spoolv carrier which differs from that hereinbe'fore described in that there is provided a rotary thread guide or slack controllerl 128l journaled .on a plug 124: fitted into the end of fthe spool and having "ex-v pansible springs 125 engaging the bore of' the spool to hold the same in place therein. -.The thread passes' through an eye 126"proA f vided -in the thread guide or slack. controller i 123 and thence-.across two stationary. thread .A guides 127 and 128 tothe braiding point at the center of the machine, said slack controller acting to prevent the thread from tangling as .it is drawn from the thread 127 and 128 and the finger 129 being located between the guide 127 and the end of the -carrier, as clearly shown, the ends of the guides being turnedupwardly and the ends of the'fingers being turned downwardly to prevent the thread escaping therefrom.
