It will be under# stood that wit-'hout such an arrangement the l braiding point would vary in .position Vaccording. to -the speed ofj'take-up and the tensionon the yarn. In other words, when the take-up is operating at coinp'ara-- ti'vely'slow speed, or when the yarns are "delivered from theirsupphes under heavy tension, 'the braiding point will be relatively device, to be later described.

The yarns af: from. the upper supplies A lead throught-he eye 19.0f thetension con-4 trolling device 20, whichneed not be here described 'in detail asjit forms the subject lnatter of a' separate' application, draw across' the edgeof `the cap 21 which surmounts 4the supply and t-hence through a guiding loop 22. The guidingloop '22- is arranged eccentric to the axis of the supply- A to direct the yarn in such "a' course that. .it' will-clear the top of the abutment 1 3 when drawing across theedge ofthe tube v 17".' The yarns z, from the lower supplies B, as they pass u nde;` the upper supplies A' bearon the top edge ofthe abutment 13,

' but itis 1 also pointed out that there isl a slightclearance between the two yarns at the point Awhere. lthe yarnsl y draw across the edge of the abutment 13. This provides that should a knot occurin either one of the yarns itfwou'ld clear the adjacentl yarn. in passing 'over or underit, Fig. 3 showing` the manner in which one 'set of yarns 'y pass'under the other set, In'Fig.; represents the .course of' 1, 'the dash line y2 the lyarn from 'the' lower 'supply as it passes over the 'yarn m, showing the .clearance between thej two yarns in this relation to pro-v vide for the passing of'lrnots.-

Two wires with their ends ldriven into bores injteythimble' 25, lthrougl'i bores inthe top ofthe support 12 and.l 'are fastened-in afcollar 29, at the.b.ottorn-91; the support,

The pins 30, 30 project through' slots 36 inthe wall of the support 12 and engage the face of a ,cam 37"which is secured to the ,head a. by thel 4 screws' 38 38 4which lalso Y. fasten the plate 6 to4 the bushing 10.

The support 12 is` fast in the post 9, as previouslv explained, and remains sta'- 'tionary with it, while 'the cam 37 rotates with thehead a.. The pins. 30. 30, through their-engagementv with t-he slots 36. prevent the rotation ofthe collar 29 and the pro-4 jections 39 onl the cam 37, .acting onl the pins, causev thecolla'r 29 to reciprocate up and down. .This reciprocatory-movement is' ytransmitted to the thimble or 'beater 25" by means yof the wires 28, causing it to more up and down on its bearing on .the .tube 17.v Fig. 2 shows the .beater in its lowermost' po-` sition and Fig. 3 illustratesit in'. its raisedposition. l

The operation'of the device is as follows:

. As the two 'heads .a and b rotate in opposite directions the two sets of supplies andB are likewise caused to revolve about the axis of the machine. The yarns from both 'sets of'supplies'are-drawnup across the edge of the tube 17 and merge in the braid Vata pointvmidway'between the end of the tube and the4 ring 18. 'A suitable take-up device, not here shown, is provided 'to feed. the fabric alongr as 'fast as the strands are intermeshed and if it is required to, -braid the fabric surround'- ing wire Orotherinaterial, for a covering. the material'is led up through theicenter .of the support/12, fedthrough the tube 17 and "taken upv'by, the take-up mechanism. TheI yarns yv from the'lower supplies pass Iover and under the yarns from the uppersupplies andthe beater 25 1s caused to recipro- A the ' formed with -Vshaped projections 3.9, which. 1

.equal in number the .whole number of sup- "plies A and B on the machine-1n this case cate upand down to engage the yarns .at

their crossing points and press them into 1 20 fabric. It will be understood that the varns" ofwhich there are eight, cross the yarnsl also.l eightA 1n number, sixteen times during lone revolution 'of the machine.- 'This occursbecause both sets'of supplies revolve' plies revolved and the 4other remained sta-` would be 'but eight crosses in y time. If only one setjofgsupi, .under each `yarn jm during one revolution of theinac'hi'ne. -lt will therefore :be seen that i y and as this occurs sixteen times during one' y revolution of the'mach1ne,`the cam 37 is so in order to'e'ngage'the pairsof. yarns each l timethey cross, the beater must be lifted six- .teen times during one revolution of the inatimed to rise to the top of-the tube'17 and i `press the crossed yarns -into afirm contact in the fabric.'` The yarns y as they ass` i f undertheryarns :z: draw acrossthe rim o the `abutment 13 with a slight clearance between i "each pair of yarns. There isa slight drag ,i i i. ofthe yarn yon this edge, however, so that 2 i "in lFig. 1, inrelation to the supply A, it will when the yarn y is-in the position indicated `not have reached apointon' the rim ofthe' abutment 13 radially in line with the yarn in; but as the `yarn y Vfollows along around4 i the rim the beater rises, so that when the 'two yarnspare crossed at or near lthe rim `they are both raised, Aand vthe under yarn In' other Words,both yarns are'lifted bythe .beater so that neither one bears on the rim freed from contact with the abutment.

of the abutment 13 when they cross adjacent thriml This is shownand indicated at 2,

` "Figl 3.` It will nowbe evidentrthat the i `beater 25.besides servingto mat the strands .35: y 'A relieving the yarns y from cont-act with the l abut-ment 13 when the yarns are crossed -in into the fabric` has this added function of line with the rim 0f the abutment, the object `being to prevent knots in one'yarn catching 40 and dragging on the other. Stated briefly; the yarns are not positiyely controlled or ,guided at their crossingpoints except where these crossing points enter the fabric, so

`that the passage of knotsis not hindered.

hlt has been found that the use of this ar- `rangement for beating up the strands results iii a much more even -and -closer fabric and the controlling of the yarns at the crossing points prevents 'chafing of the yarns or breakages' when knots occur.

`Although weh vedescribed our deyice in ,i detail with the preferred' form land arrangement of parts` 'and as app-lied to a certain type of machine,A it will be evident that finodicationsin the structure and application of the mechanism might be made which .would comewithinthe scope rof thisinrention, and, therefore, lwedo not. limit ourselves to the precise construction shown, but
