This invention relates to improvements lyresistingthelateralstress imposed when the in braiding carriers of that kind in which a weight is employed for actuating a stop mobase or support, movable by suitable and usu-- tion mechanism.

This bobbin or holder is adapted to turn on a spindle 14 extending vertically from the base, and the lower head of the bobbin or holder is furnished with ratchet teeth 16 as is usual for cooperation with the let-off latch having the ratchet engaging blade member 20 at one end. This latch is received in a vertical slot 15 in the base 10 and is pivotally supported by a pin 18 intermediate its ends, the rear end of the latch preferably being slotted as shown at 19, thus providing the upper finger 32.

The slot 15 in the support is preferably of just suflicient Width to receive and permit of a free swinging movement of the latch, and the side walls of this support extend for- Wardly of the pivot point a substantial distance, as at 21, to support the tooth-engaging portion 20 of the latch at a point close to or adjacent the point where its blade engages the ratchet tooth of the holder so that the lateral strain or thrust caused by the tension of the yarn and its take up upon the package, as transmitted through the ratchet teeth is absorbed by the supporting side Wall portions 21, and thus these rapidly and intermittently occurring lateral thrusts or blows are not transmitted to the pivot pin 18, so that cramping of the latchon its pivot pin and rapid wear of the bearings is prevented.

A standard 22, preferably integral with the base, projects upwardly from the rear part of the base, such standard preferably being of non-circular, for example, substantially elliptical cross-section, as shown in Figs. 4 and 5.

On this standard slides a yarn tension weight 23 having a guide opening substantial- 1y conforming to the contour of the standard so as to have a sliding fit with the latter. This weight is provided with a yarn engaging loop in the usual manner at the rear side of the device.

Spaced from the standard 22 and at any convenient point, here shown as the rear of the standard, is mounted a post 25 fixed at its bottom to the base and at its top to a lug on the standard 22 and which is encircled by a coiled spring 24 whose upper end engages a fixed stop, and whose lower end bears upon a collar 24F freely sliding on the post. The collar 2 1" is adapted to overhang a part, for example, a projecting lug 26 of the weight 23, it being understood that the shape of the standard 22 and of the opening in the weight is such as to prevent rotation of the weight so that it is not necessary for the latter to engage the post 25 in order to sustain lateral thrusts such as are incurred when the weight a is employed for actuating a stop mechanism.

Thus, as shown in Fig. 4, the lug 26 of the weight has a large opening through which the post 25 passes, but without contact with the weight.

Also, slidably mounted on this standard 22 above the weight, is a latch lift slide member 27 to which is fixed the latch actuating rod 28, the upper end 29 of which is guided in a slot in a boss 30 011 the standard 22, and the lower end of which is provided with a loop 31 to receive a finger 82 formed by the slot 19 in the end of the latch 17.

On this latch rod is a coiled tension spring 33, whose upper end preferably engages a collar freely sliding on the rod 25 and bearing against the under side of the boss 30, while the lower end of the spring rests on the slide 27 to insure a quick return action thereof, and this latch rod is. offset inwardly as at 34 below its slide to engage and slide against the substantially flat forward face of the standard 22. By this construction the rod is prevented from tilting about the part 27 as an axis so that the loop 31 at its lower end is prevented from inadvertent disengagement from the latch and its upper end 29 is prevented from inadvertent disengagement from the slot 35 in the standard, as best illus trated in Fig. 6.

In some instances, instead of pivotally mounting the latch in the package support 11, as illustrated in Figs. 1, 2 and 3, I may form the latch as'best illustrated in Figs. 7 and 8.

As thus shown the latch 36 is of U-shape and slides vertically on the fixed guide lin 87 projecting upwardly from the base of the carrier, the tooth engaging blade or member 38 of the latch being arranged to engage the upturned ratchet teeth 89 on the holder 40 My improved construction of braider carrier is very simple and practical to manufacture and by supporting the latch adjacent or close to the point where it engages the ratchet teeth of and cramping and wear is prevented, and the action of the latch is very much easier than when unsupported at this point, and, therefore the wearing life of the latch is much longer, and the yarn release will be much more delicate in its operation and a better control of the yarn let oif obtained.

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

I desire it to be understood that I reserve l the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. In a braiding carrier, a yarn holder having ratchet teeth, a relatively fixed support on which said holder is rotatably mounted, a let-oif latch cooperable with said ratchet teeth and operable the package holder, binding by yarn tension to control ing ratchet teeth, a spindle on the rotation of the holder, and guide means for the latch adjacent to its tooth engaging portion to support the same at that point against lateral thrust.

2. A. braiding carrier comprising a base, a yarn holder having ratchet teeth, a relatively fixed support carried by the base on which the holder is rotatably mounted, a letoff latch cooperable with said ratchet teeth and actuable by yarn tension to control the rotation of the holder, and a latch guide integral with the base and arranged to support the ratchet engaging portion of the latch against lateral stress.

3. A braiding carrier comprising a base, a yarn holder having ratchet teeth, a support carried by the base on which said holder is rotatably mounted, a yarn let-oft latch arranged to engage said ratchet teeth, and a latch guide fixed relatively to the base and located adjacent to the tooth-engaging portion of said latch to supportthe latter against lateral thrust imposed by the ratchet teeth.

a. In a braiding carrier, a yarn holder havwhich said holder is rotatably mounted, a let-oft latch pivotally carried by the support, and a thrust bearing located intermediate the pivot point of the latch and the tooth-engaging end of the latch to support the latch against lateral stress.
