This invention relatesto a yarnpackage carrier f or ai.. braiding z machine, and". has f or Aits object. to provide a=carrie1t Whieh;may. operate. on lighter.v weight yarn withles'ser liability of. rupturingor breaking. the. same.. than the average carrier in use:

- A-.pair-of guide.y standards=19 and120lextend up- Wardiy from. the base lilfandarel ppsitionedrso that the:` spindle 15de-incline' Witlrthem.. Match lift is'j slicabley upon the rod:v ory s tanolard- 20 and is.. forced' downwardly byl means. ott ai springV 221 encircling the.-` rod" 20.` The; latch:- lifty has; a fingerA 23 to eng-age; beneath the;l lip 24g ofgthe latchY to raise the` same in; controlling thedet-oil act-ion of' the yarn.

A.tension Weight member 25 informed of sheet metalL by forming the sameinto generally U.` shape. having portions 26.- and 2'1-V provided with openings. to receive the guide. standard.. or. rod. 19. and slide. therealong, and from the. bridge portion 28` of this Weight. there extends an arm. 2,9. having a iinger 30' extending therefromin glenerally the form of 'a hook beneath Whichthe yarn extends. This yWeight is also provided With-an; arm 31* which engages the lip 32t on thelatch lift-"21' toraise thesarne, and` also provides an 4abutment for purposes hereinafter mentioned.` Y

A stop 33 slid'ably engages. the rod: 19 and i's providedA with. a ange 34 which When-Y in lover-1 ered position as illustrated in Figure 2, Will engage: the; stop mechanism of? the. machine to. a1?- rest.. the motion thereof; and in ordeithat; this stop; member` may be` lifted to; inoperative; posi-f tion, I have provided a support member pivoted at 36 on the base, a nger 37 of which engages beneath the stop 33, while an arm 38 extends upwardly from the member 35, as shown in Figure 1, generally vertically and rests against the abutment surface of the arm 31 of the weight to prevent its swinging in a vertical plane about the pivot 36, whereby the stop` member 33 is held in raised or inoperative position.

In operation, the yarn 39 extends from the package 16 through the pigtail guide 40 beneath the tension weight guide hook 30 outwardly through the pigtail guide 41 mounted on the top of rod 20 which extends above the rod 19, the

weight being slidable along the rod 19 under action of the tension spring 42 to supply the sufncient amount of tension on the yarn, it being understood that as the tension weight is raised by the yarn to substantially the position illustrated in Figure l, that it will raise the latch lift 21 and latch 17to permitrotation of the package and thereby supply additional yarn for use, whereupon the weight will slide along its guide rods totake up this slack, the same being always in contact with the arm 38 to maintain it substantially in vertical position and thus cause the member 35 to support the stop 33. Should, however, the yarn break, the tensionweight then will immediately slide along the rod 19 to a position illustrated in Figure 2, and its arm 31, will as illustrated in Figure 2, move from along the elongated surface of thearm 318 to the offset portion 43 thereof, permitting the member to swing inthe vertical plane about the pivot, illustrated in Figure 2, and the weight to drop positioning its ange to engage the stop mechanism of the machine and thus arrest its motion.

In Figures 5, 6 and 7 I have illustrated in the base of the carrier an additional spring means for the latch which may be used additionally to or in place of lthe spring 22. This means is provided bymounting a plunger 45 in a bore 46 in the base with a', spring 4'? forcing the same outwardly. The plunger is notched as at 48 to engage the edge of 'a notch 49 in the pin 18, whereby to rotate the pin 18 and in consequence the latch 1'7 which in this instance must be secured thereto to turn therewith.

It will be noted that the guide rod 20 extends above the guide rod 19 and that the thread guides 40 and 41 are both carried cna single rod.

A'The l'pigtail guide 41 is removably secured at the top of-the guiderod 20.` A bracket 51 has a pair of 'spaced portions 52 and 53 engaging the rod 20 and rests on lugs 55 projecting therefrom. The portion 53l extends across to embrace the guide rod 19 and forms an abutment for the upper en d of springv 42,y the" abutment being held in place V by a spring 54 acting between Yit and the pigtail guide 41, whereby the spring 42 may be easily removed for` replacement when desired.V jBy the foregoing arrangement, the part which must withstand the abuse of striking the stop mechanism and thusbefnecessarily of a somewhat heavy construction "to withstand such shocksv and jars, is not carried bythe yarn, the yarn tension weight being separate therefrom and reciprocating independently thereof, whereby lighter thread 'maybe usedon the braider carrier without danger of breaking the same.

While I have described certain construction forms which embody the principles Aof my inventiomit is obvious that other desired changes in arrangement Vmaybe made Within the spirit and the scope of the invention as dened in the appended claims.

I claim:

In a carrier for a braiding machine, a guide standard, a stop member slidably mounted on said standard, a separate tension weight for the yarn movably mounted on the carrier, 'and a member engaging said stop member for maintaining the same in inoperative position, and said separate member also engaging said weight to apply pressure at right angles to said standard, whereby the action of said member is controlled in its action by the movement of said weight. y
