To all whom it may concern:

' Be it known that we, EDWARD F.'

is fully set 'In'general aspect the machine-iresernbles intervention of guides and deflectors. The

advantage, as it effectsfa most direct path of travel for the yarn, is obvious; and further, as the supplies revolve at high speed, and are therefore subject to-materia'l centrifugal action, the said centrifugal "action is balanced and neutralized by gravity. This results in more uniform pressureon the track and a; reduction vof side strain, and,

' therefore, uniform, "evenly di .tributed- 'wear' of the parts. The principle involved is that which dictates the elevation of the outer-rail on a railroad curve, andrequires nodi'scus- Theinclination ofbraider supplies iswold,

v persaand therefore admittedly not, per -se,

of the invention, but so far as 'we'know', such 5 inclination: has involved additional mechan1sn1-,and-. a complicat onof devices which we avoid.

Specifically, there are two sets of supplies A and Bwwhich rotate about a central post 2.-.- -lhese--sets of supplies are both mounted on the carrier frame '5, the supplies'A, slidably, on'a sectional circular track 3; the sup- Plies B, fixedly (with relation to the carrier frame) ."on spindles 41, secured to said carrier .framel Adjacent the supplies A is' the driving head orplate 6 which rotates in a direction;

opposite to the carrier frame or driving head 5, and by devicesto be described engages the carriers 7 on which the supplies A are mounted, and revolves them in a. threetionopposite to the direction of revolution of the supplies B. The arrangement of the driving plate and carrier fran1e,'their mode of mounting and connections will be later described. Not'e that the relation of the two sets of suppliesis such that when one of the sup plies A registers with a supply B, their individual axes are. substantially perpendicular, and. the longitudinal dimension of the supply is substantially bisected by the intersection of the axis of the supply A imaginarilyextended downward, as

I indicated by the broken line m-fir'in Fig. 3.

is'of a flat, circular plane, not of-a conical or cylindrical surface; the engaging part or prefer to term. it, is made preferably of sheet- *inetal to conform to the track 3,,extending TThe track 3. on which thecarrier T travels Fig. 7;

- supplies across the top, down the edges and beneath, sufliciently to prevent said runner from lifting, as shown in' Fig. 3, but more clearly in The deck portion 9 which supports the bases ofthe supply is made separate and se-.

cured to the runnerv 8.- It,is of lenticular contour, so that the yarns .from the lower .13 shall easily ride over or under said deck .portion. This further brings the supply .in close proximity to the track with its base crossing and extending below the traeln' thereby lowering-the center of gravity and diminishing its distance from the track. It'will be-seen that by the arrangement of the two sets'of supplies axially perpendicular-to each other in respect to the thin flat circular track, the supplies and the intermediate track are brought into very close proximity, the, track being practically about 45 to theaxesof each set, and thereby the 'apparatus is rendered more compact and the c'enterof gravity of the supplies lowered.

Further-this construction and arrangement rectly engage the carriers on the track there is secured a positive coupling of the driving plate with the carriers; and the drivers can .be located in grooves in the plate so-as to move radially from the axis when driven by the cam in the same plane. This not only involves simplicity of mechanism and direct application of the force developed by the rotation of the cam, but also insures a firm en gagement of the would be detrimental to the proper control of the carriers. WVhether the said yarns pass over or under the carriers is determined by devices which will later be described;

. In behalf of lightness to avoid inertia and minimize momentum, the deck is'of skeleton structure, consisting of a rim having the lenticular contour aforesaid, and a cross ticdle to receive the supth, runner, two ears-12142 are formed Where theinterio'r metal is. cut out, and these are formed at ,:the-requ'isite angle to secure said deck and runner at :the correct relative -incl'i1iation The m'ode of. securing may be of any usual form,

v though we prefer to employscrews -l3 13; for the-"purpose. second-"cross'tie 14 is formed near one end of the carti'er'for-the-purposes to be later described. -Inthrunner an'ear 15 is turned up opp'ofsite'the-middle cros's tie of the (h ck and in saidcro'ss tieand ear are aliniiig holes 16 whe reby the carriers drivers with the carriers, preventing the play and backlashwhichand '1? to receiveand secure the supply spindie 11.

The edge 18 of the deck which is "adially inward toward the axial post 2 of the ma chine is turned or formed downward, and is further pierced with two apertures 19 and 19", (Fig. 5) ,which provideengagement means 7 are driven. Preferably the surface of the downturned portion or edge 18 is inclined to both the plane of the deck and of the track, it being parallel with. the path of travel of the under supply yarn Z), as it leads to the carrier, or, in other words, parallel with the surface that would be described by a line extending from or past the carrier deck to the slack controlling guide to which reference will be later made. Owing to the varying angles at which the yarn 1) draws by the carrier, the downturn is made of varying depth or extent. p

To engage the carriers there are drivers 20 mounted on the driving plate 6, each of circular areal form, mounted .in a track or groove of similar form. The engaging ends of these drivers are beveled (see Fig. 6) or conformed to the surface ofthe down turned deck port-ion aforesaid, so that the least possible movement shall be required to engage the drivers with the carriers. These are operated-from a cam 21, see Figs. 3,51: and (3, secured to the carrier frame 5. Engaging the groovc22 of this cam is a roll carried on an arm.2-'1 which is secured intu'rnfto one of the drivers 20. A series .of these drivers is so coupled together that the whole. series is controlled by one roll 23, as, for example, by the segmental racks 25, The action-of this mechanism is to cause the drivers to alternately engage the carriers byone'or the other of the apertures 1. and 19? aforesaid.- so that a yarn may pass the drivers-without obstruction or interference.

The mode of-coi pling, as well asthe anode of 'ac-tioirof the drivers in engaging the carriers and. pass ngthe lower yarns, has

all beenful'ly disclosed in our prior pending application, and should require no further explanation. 4

' Carried by each driver is the switch 26 which. in Fig. 4. is shown in two positions.

26 and 26. When in position 26 the switch is thrown outward and closes or obstruct; the slit 2". so that theyarn is engaged by the inclined edge of the switch, rides over it onto the outer edge 29 ofthe carrier deck and travels outward around the yarn supply carried'by said carrier.

26 shows the position of the switch withdrawn, leaving the slit 27 open so the yarn can travel into it and inwardly around the yarn supply on the carrier. I

In brief rsum, then. we have. two sets of supplies posed axially perpendicular to each other (consideredwl en the two sets register),'eaclil delivering yarns toa substansubstantiallyin a common horizontal plane,

The axes of the supplies A are so inclined that the' axial lines pass substantially tangent to' the surface 'of the abutment .28. At

the'top of each of the supplies A is a guide --"Which is positioned enougheccentric to the axis of the supplyto raise its yarnfro'm .ithe'abu'tnient This permits the yarn b from i the suppl es B to pass betweenthe yarn a of'lthe supply A and the abutment Without drag and abrasion of the two yarns. In order that the yarn b shall not drag on the abutment, the latter is rotatable; its bearing being' formed by -a sleeve 28 turning on the .bered between the ends. The' abutment 28 willjbe inductively rotated by the contact of the revolving 'yarns'in' their travel. By

this rotative engagement the frictional rehave made this in c rcular plate, rotatable about the axis of sistance totravel of the yarns is minimized, thereby reducing l ability to abrasion and jhreakagey .and tending to a better braided product.

----.-.The tendencyof the braiding point to rise,

is overcome by the gatherer.-.so-called, '32; novel fashion as a l the stem 33 and adjustable in varying posi t'ions, both. rotatively and vertically, by the setfscrew 34, Figs. 9 and 10. The plate is 'piercedwith a circular sequence of holes of different size. to accommodate different sizes of braid.

Istud 28 the latter turned down or chamvariable-by the screw 46 and thumb; nut 47-.

The bearing 35 for the stem in the main frame is so located, eccentric to the line of braiding that each and every hole can be'rotated into the braiding line to'receive and gather the braid as formed' The triangular projection 35 of the bearing'35 serves as a pointer or marker to set the holes by. I

To take the thrust of the carrier plate 5 and the driving plate 6, ball bearings are introduced as shown in Fig. 3.

chine is the ball race 63 and attachedto-t he gear 58 is. a corresponding race -6l.;--:.Interposed between the two races is the ball cage '65. holding balls 66.

The gear 58, in addition to being rota- I tively secured to the sleeve57',,abuts a shoulder 67 which prevents the sleeve 57 slipping through the gear 58 impelled by the weight of the driving plate and the parts .which it carries. Superimposed upon the body of the gear 58 is a third ball race 68 on which is. a

ball cage 69 with balls 70, and engaging said balls is a fou'rth ball race 71 on which rests.

the hub-59 of the carrier frame 5. This fourth ball race is secured to said hub 59 by'the pin 72.

The gear'tiO is preferably secured to the hub 59 by a key 'YS, and the gear-58 to the sleeve 57 by a key 74. The main shaft 48 is mounted preferably ina bearing 75 of the pedestal 76 and a bearing 7 7 of a pedestal 78, and at its outer end has tight and loose pulleys 79and 89,

by which the action of the machine is effected. or is-dis c ontinued. ,This control is eil'ected through the belt' shipper fork 81, secured to the shipper rod 82, Figs. 3, 14 and 15, which in turnhasa bearing 83 on the pedestal 78 and a bearing- 84- on the pedestal85. Secured. to the end of the shipper rod is the handle 86, at one end of thebearing- 84;, and on said shipper red at the" opposite .side of the bearing 84 is the stop collar 87 to. limit the extent'of movement of said shipper rod.

vAdjacent the stop collar-87'is a lock notch orsh-oulder 88 on the shipper rod 82 Figs. 13, H and 15. This shoulder 88 is engaged bya rocking detent' 89 which; by such engagement, resists the tendency ofthe spring 90 (see Fig.1) to throw, by the shipperfork I lays in stopping. and further to preventdamage to the yarns or fabric in case of breakage Or other accident. we employ 'the brake system now descrlbed.

The carrierframe 5 and driving plate 6 are provided with ln'ake seats 94:- and Figs. 1, 3 and 8, preferably formed as portions ofthe

gears

58 and 60. Engaging theseseats are

bands

96 and 97. Both bands are secured and operatedin the following manner (see. Fig. 8). bandare secured

blocks

98 and 99. Con- .nected, with the block 98 is a cam lever 100 which is rockable about the pin 101v n the rockable arm 102. The other block 99 is connected with the cam lever 100' by the link 103- which has at 10 i provision for micrometer adjustment to regulate the degree of friction of the brakes.

Upon the shipper rod 82 is a pro ection or pin. 105 adapted to engagethe cam surface or incline 106 when moved in the direction of the arrow 0, asit is under action of the spring 90. Such engagement causes the cam lever 100 to swing in the direction of the arrow (Z and constrict the brake band on its seat, thereby stopping the member of which the seat is a part. As the same action occurs with both bands, and concurrently,

further description is not required, except to note that the relative arrangement of parts for one band with respectto that for the other is reversed to accommodate the opposite rotation of the

gears

58 and 60 and their related parts.

Means have been set forth for manually controlling the starting and stoppihg of the machine, but more essential is the automatic control, by the yarns, of the stopping, as, for example, when any one of the yarn supplies is exhausted or when-any one of the yarns is'broken or unduly slack.

Mounted on the carrier frame 5 is a longitudinally slidable pin l07 (see Fig. 14) beveled'at-its upper end 108 and also at its lower end'109. The lower end 109 is in such position that if the pin projects downwardly a suflicient distance, it will engag the arm 91 of the bell crank lever abovureferred to, move it, and thereby effect the stopping of the machine, in the 'inanner-before explained. The pin 10,? is operated by means about to be particularized, by each or any-of'the supplies of the upper bank or set. Adjacent each supply and traveling with it is the device shown in section in Fig. 13, consisting of a tube 110 having a longitudinal side slot, a guide 111 at the To the ends of each top of the tube and suitably secured thereto,

a slidable sleeve 112, a second guide or loop 113, and a pin or projection 114:, the two latter being secured to the sleeve.

The pin 114 shows more clearly in Fig, 1-1, where the relation of this device to the supplies is indicated. The yarn a draws from the supply package A through the 1 arm 91, the following provision is made: In the side ot the said pin 10'? will stay down until said pin 114 is drawn up and withheld from ent gagoment. with the p n 10.. When, however, the pin 114 is not held up by theyarn, because the latter is exlmusted, broken or becomeunduly slack, it. engages the beveled top end of the pin 107. forcing it down and causing it to engage the bell crank arm 91. to raise the detent S9 and release the belt shifter, causing the machine to stop, as described. But there is only one pin 107 and it rotates with the carrier frame 5 and as exhaustion, breakage or slack of the yarn may occur when the pin 107 is not near the the pin 107 are out two notches 115 with either of which may engage a. spring 116. This is preferably a flatspring secured to one of the bearings 117 and 118. The tension of the spring is such as to permit easy shifting of the pin 107, and the form of its end and shape of the notches 115 such as to retain the pin 107 in whatever position to which it shifted, and also complete said shifting after having been started by other agencies. If then the pin 107 can or cap 127 which in turn, is secured to the tube 110. lVithin said tube, and between the plug 127 and theplunger head 123 is the sprin 128, which resses downward the plunger 129.

The lower end'of the plunger 129 is beveled, and engages a correspondingly beveled sided, or V notch in the stem 130 of the brake shoe 125. The extremity of the plun-. ger 129, and the brake stem 130, are therefore engaged wedgewise, so that the action of the spring 128 downward, is transmitted laterally to the brake stem 130, and forces the brake shoe 125 against the disk 126.

The spring 128 is materially heavier than the spring 121, so that the latter has practically a full range of movement without affecting the brake action; but. should a resistance to delivery of the yarn occur, so great as to render breakage liable under the existing tension, this resistance, will cause the spring 121, to close entirely on itself. Then compression of the spring 128 will begin, permitting the plunger 129- to be withdrawn from the brake stem 130 by the yarn,

should be forceddown at a point, say diametrically opposite the bell crank arm 9.1..

bell crank arm 91 has been engaged and operated. But the bell crank arm 01 has a limited movement, only suflicient to release the shipper rod 82. It also has a beveled extremity 119 which engages the lower beveled end of the pin 107, so that when the bell crank reaches the extent of its movement, the reaction of its resistance communicated through the beveled extremities 109 and 1.19 aforesaid, and the. pin 97 is thereby replaced in its neutral position out of range of engagement with the arm 91. r

The movement of the pin 107 is only initi ated by either the pin 114C or the arm 91-. The relation of the spring 116 and the notches 115 is such that the pin 114 or the arm 91 need only move the pin 07 sufficiently to pass the high point 120 that between the notches, past the formed end of the spring 116, and the latter, by wedging action, completes the movement. I

To insure action of the pin 114;, we prefer to employ a light spring 121 Fig. 13) Which is interposed...)between what we term the piston anti the plunger head 123. The piston 122- is connected with the sleeve 112,

acting through the loop guide 113, the sleeve 112 to which it is secured, and the piston 122 with which it is connected. This relieves the tension action of the brake shoe 125 on the disk 126, and permits free rotation 'of the supply. In other words, the spring 128 and the spring 121 serves only to control the pin 11d, and insure its engagement with the pin 107 when released-by the yarn.

The stop and tension devices for the lower supplies B are similar in construction-and arrangement to those for the supplies A,

lent. The rod 11% engages directly with a projection 1.41, or a part carried thereby, Figsil l and 15, from the rod 1412 on which is preferably in the form of a wlre extending through an opening in the bearing 92 of the pedestal 85 and mounted at the top of the wire is a fiat spring 148 which is sulficiently rigid to cause the tilting or the rod 142 to release the detent 89, when engaged by the rod 11%, but resilient enough to yield to'allow the rod 114 to pass by without hindrance.

The supplies B have a spring take-up, or slack controller, embodied in an. arm 132, Figs. 16 and 17, to which is secured a staple 138, on which is a light coiled spring'134,

bythe screw 124:, which slides in a longitudinal slot in the side of the tube 110. Em-

bodied with this device is the tension =flel vice, which is of a usual form: viz r-a brake shoe 125, engaging the periphery of the disk 126, which is a part of the supply holder. But we apply and regulate elastic pressure of this brake shoe in a 'novel manner and for. a further purpose.

The guide 111 is secured in a solid plu which extends around the loop of the staple and along-both legs thereofsee Fig. 16.

Sliding on the staple is a guide 135 which tends, under action of the spring 13:1 aforesaid, toward the arm 132. The function of the slack controller is to yield when the yarn 7) passes over or under the carrier deck. of

the supply A, to compensate for the extra yarn taken up by the deflection; or, in other serves only to control or modify the tension,-

save in that there is no rod 107 or its equivathe detent 89 is mounted. This projection" effects of the abnormality.

substantially coinc'dent with the path of travel of the axis of the supplies A, but deve r'ted by the switch above referred to, the said-yarn would always trayel below, or'rajdially within the slits 27.

The yarns pass therefrom to the guides 111, thence to the loop guides 113, thence to thetake-up 135, and from there, by'the supplies A, to the abutment 28, where they enter the braid.v

To insure free passage over A, the latterhave at their upper'ends caps or heads '136 with highly polished edges, overwhich theyarns 6 pass, withthe least "possible. resistance. r tects the supplies A from abrasion and also insures/fa constant angle of convergence of thel yarns bQf -WithOut this provision, thesaid. angle would vary as the supplyv A ditminishesin diameter: 301,1 O-Vable from the supply spindles, are non- ,ixiztz'itable, being rotatively fix'ed by means of 'the.'
