n CARRIER FOR BRAIDVING MACHINES Application med ruiy i, 1929. kseriai No. 375,077.

This invention relates to an improved construction `of carrier for braiding machines; and has for its object to provide in such a carrier a vcoil spring arranged to produce a iquicker acting and more sensitivepand reliable -tension for controllingjthe yarn feed than was possible with the old tension weight.

A furtherobject of the invention isto prostyle gravity `vide a latch lifting rod which is guided oni the weight standardand on which rod is y mounted a coil spring to act upon the weight;

The invention further consists in forming the lift rod in U-shape, one end'of one Varmi 1 being attached to the feed control latch and the other arm carrying a coil spring to act With these and other objects in view, ythe invention consists of certainnovel features of construction, as will be more Vfully described, and particularly'poin'ted out in the appended claims.

In the accompanying drawings:

Fig.v 1 isa side `elevation showinglmy improved construction of carrier vwith'the tension weight in partlylifted position and with the latch in engagement.l g Fig. 2 is a view showing the base portion of the package as riding-n the rocker latch,

the latch being withdrawn from engagement with'the ratchet teeth of the package.

Fig, 3is a front view partly in section with the package and latch removed showing the bifurcated liftrod as being guided 0n ther weight'standard and showing the coil spring on one arm of the lift rod.

Fig. 4is the same as Fig; 3 showing the weight in raised position in engagement with the abutment on one arm of the lift rod and 'the spring compressed on the other arm ofl the rod by the weight.

AIt Vis found in the practical lconstruction andoperation of braiderY carriers `of this h, Acharacter, of advantage to construct a. lift rod for the yarn 'let olf latchwith a pair of arms, one arm being connected to the latch while the other arm is guided in the weight standard and is ,arrangedv to carry a coil spring to exert a tension on the weight to asl sist in accelerating its return movement after having operated the let off to release more yarn from the package and the followingis a detailed description of the present embodimentV of my invention and showing one construction of carrier by which these advantageous results may be accomplished:

rWith reference to the drawings, designates the body of the carrier which is provided with a package spindle 11 on which 'the yarn package 12 may `be mounted. 13 designates the weight standard which eX- tends upward from the body-member and which is preferably cast integral with the' body and is of-the'usual' oval shape in cross section to receive and guide the yarn tension weight 14 to slide vertically thereon.

`This standard is herein shown as ybeing provided with a front boss or lug 15 which is drilled tov receive and guide the downwardly turned arm 17 of the latch lifting rod 18.V This latch lift "rod is preferably` formed in elongated U-shape one arm 2O of which has its end'19 looped aboutjthe end 21-ofthe rockerlatch 22 and this arm'20 Vis provided with an odset abutment 23 for the purpose `presently described.v i

'Thellipper `end of this vrod hasa return V` bend 24 and the downward turned ariiifniem-v ber thereof extendsthru andlis guidedfin the boss 15 on thestandard 13. The free end of'this arm extendsdown' thru an eye 25fin the weight 26 and al spring 27 is coiled about `this arm717, with its upper end 28 abutting againstthe-boss 15 while its lower end 29 abuts against the boss-y of the weight so that whenfthis weightis caused by the tension of the yarn to slide upwardly on its standard 13 it compresses `the springr 27 and engages the abutment23 on the arm -20'of the liftrod to Arock the latc`h-22and withdraw its tooth 29k from, engagementrwith the teeth 30fon the bottom of the package spool 24 thus releasmore yarn 31, to be drawn-from the package y12"and when'sufficientvhasbeen drawn from this' package the spring 27acts upon the weight toquickly force itdownwardly from engagement-with abutment 23. This downing the vpackage spool'to rotate and permit f i downward vmovement of the lower end portion of the spring on this arm 17 also serves to assist in accelerating `the initial reeiigaging act-ion of the latch with the teeth in the spool to arrest the releasing rotation of the package and maintain a comparatively constant tension on the yarn during a braiding operation even though the carrier is running at a high rate of speed.

The yarn 3l as is usual is led from the package l2 thru an eye 32m the standard 13 down around back of the weight thence up thru the eye 33 to the point of braiding.

'By my improved arrangement of latch lift and tension spring theyarn take up action of the tensionv weightis greatly accelerated over thevold style gravity weight permitting the carrier to run at a much greater velocity than would be possible without the assistyance of such a spring.`

The foregoing description is directed solely towards the construction illustrated, but

, I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention beingdelined and limited only by the terms of the appended claims I claim:` y y l. A carrier for braiding machines havling means for mounting a yarn package thereon, a weight guiding standard, weightv slidable on the' standard, a latch for controlling the rotation of the package, a movable latch operating lift rod guided on said stand- ,ard, a compressible coil spring on the lift rodl continually engaging the weight, and means whereby the lifting` of the weight a predetermined distance against ,the spring tension lifts said rod to move the latch to release .the package.

2. A carrier for braiding machines having means for rotatably mounting a yarn package thereon, a weight guiding standard, a

' latch for controlling the release of yarn from the package, a movable latch operating lift Vrod guided on the standard and having anabutment thereon, one end of said rod being connected to said latch, a weight slidable on the standard and arranged toengage the :abutment toinove the latch to release the package, and a compression coil spring on the rod continually engaging the weight to accelerate its movement from yarn releasing o. nacarrier or rai ingmac ines, yarn package supportingmeans, a tension weight,

l a Aweight guidey standard, a. lift rod guide Y member on the standard, a latch for controlling theyarn release movement of the package, amovable latchr lift rod guided 1n said guide member a spring coiled about said lift rod and continually engaging with said 4. In a carrier for braiding machines, yarn package supporting means, a tension weight, a guide standard therefor, a latch for controlling the yarn release movement of the package, a movable bifurcated lift rod attached to said latch and guided on said standard, an abutment on one arm of said rod, a coil spring carried by the other arm of said rod and continually engaging said weight whereby when the weight is lifted a predetermined distance it engages said rod abutment to move the latch and release more yarn, the spring acting to accelerate the return of the weight from yarn releasing position. y Y

5. .A carrier for braiding machines, yarn package supporting means, a tension weight, a guide standard therefor, a rocker latch for controlling the feed of the yarn package, a'movable bifurcated lift rod having one arm attached to the latch, a weight engaging abutment on one of said arms, a coil spring carried by the other of said arms and continually engaging said weight, whereby when the weight is lifted it engages said abutment and the latch is operated to release the package and the spring is then caused to act upon the weight to accelerate its movement back from yarn releasing position.

6. In a carrier for braiding machines, yarn package supporting means, a latch for controlling the yarn releasing movement of said package, a guide standard, a movable weight guided by said guide standard, a movable lift rod secured to said latch and guided atone end in said standard and at the other end in said weight, and an abutment on said lift rod engageable by said weight to move the latch to release the package.

In testimony whereof I affix my signature.
