The? so -calleddoubled-V yam-is wound. upon the:- spool .15, and .theiparticularrneans for ginding'theyarn-'or-:d1iving the 'spool is immaterial. In threading the apparatus-the yarn- 1s=led from the bobbins-over the-sup portlng-rod 5.

strand leading from the bobbins carried thereby. It is-to effectively compensate-for this: uneven condition'amhto" secure a uniform tension of the several; strands being doubled, that this-inven tion is designed; To that end I provide a means whereby the brakes 6-6''6 will: be under the controlv ofi the respective-strands;
19 is a bracketcalrying a"suita1ble=spri-ng{ mechanismarranged to bearagainst the several'b'rake barsS with a inn-form "re'ssu-rei; In the particular form' shown, asing e 'sprin'g 20-is employed.
2-1 is a tension adjusting sorew;
The spring 20 works against a larger-122.,- which carries atits forward end a' hinged cross'bar 23. 1
24-44 are two bridging bars arranged te' span the gaps betweenthe brake 'bars- 8; being supported on-thebars respectively by pins 2525. The endsof the'hinged; cross ar 23" engage in sockets 2&*26 on the:- bridging-bars 24 in such amanner asito fer the pressure'ofi the spring 20 first to the bridging bars and thenceto the brake-bars 8=8'-. The-faces of the=brakes proper may: be provided with any desired" material, suchas leather.
In normal operation each of-- the brakes bears lightly and uniformly against the cylindricalpart 7- ofthe spindle; If for any reason the tension of the yarn-leading from any one of the bobbins 1s greater than it should be, this increased tension will have the eflect of drawing its-respective brakeshoe away from the cylindrical part 7 of thef spindle, thus letting it run more freely and immediately giving'up the necessary-slack t'orovide a tension uniform with the strands eading from the other bobbins; This draw ingbaekgof one brake-shoe forcesthe' plunger 2% against'springj 20 andincreases the tension This additional tension willof the latter. y Y obviously be distributed back' througli=the bridging bars of the other brake lever or levers inthe groove, thereby slightlyin equalize and:

ment. By this means a very quick and r:-
i; will always be impossible to secure a plurality of spindles in a machine of this type which will run with absolutely the same freedom. This is one cause of variation in tension. Furthermore, variations in the amount of yarn on the 'difierent spindleswill always tend to produce a-relative variation in tension of strands leading therefrom. This would come about 'by the diflerent. speeds of the bobbins, owing to the dinerent diameters, determined by the bulk of thread thereon. These and other causes in. ma-
chines of this character will always produce variations in tension of the strands leading from the bobbins, so that it is only .by the addition of a compensating and tensionequalizing means such as described herein,
or an equivalent device, that uniformity of tension in' all of the strands'will be secured.
The great advantage, therefore, will be apparent to the mechanic skilled in the art,- by reason of the fact that practically all danger ofimperfect stock is ehminated by the employment of this mechanism.
must 'force back both of the bridging-bars 2424. To relieve one of the end brakes, one of the bridging-bars 24 only tilts back, as shown in dotted lines in Fig. 4. By this or an analogous arrangement the spring pressure applied to the several brakes is always uniform, and as a result the tension of each of the yarn ends leading from the bobbins will. be maintained substantially uniform.
While I have shown the mechanism in the 1rireferred form, obviously it may be modied in many res ects Without departing from the spirit an scope of the invention, for example, while three s indles are shown,
the invention is applica le where two or more are employed.
It will be noted that the tension control is effected by arranging the yarn sup ort and the eyes on the several brakes, and tlie drawing-oil means, so that the same are out of line. This variation in alinement may, of course, be modified at will, so long as a variation in tension in any one or more of the strands leading from the respective bobbins will relieve the brake action.
