' CARRIER FOR BRAIDING MACHINES.

- Application filed December 31, 1924. Serial No. 759,015.

This invention relates to improvements in the construction of braiding machine carriers and is an improvement on my earlier Patent No. 1,479,397, January 1, 1924. This invention has for its object to provide a carrier which is extremely light in Weight, whereby high-running speed may be obtained, and the carrier is provided with a coiled spring acting upon the yarn tension Weight to accelerate its take-up action upon the yarn.

A further object of the invention is to form many of the operating parts of the carrier of pressed sheet metal thereby greatly reducing the weight of the carrier.

A still further object of the invention is to provide a pair of cooperating standards on the carrier, one serving as a vertical guide for the weight and its operating spring, and the other serving to cooperate with the first standard to provide a lateral guide for the weight and also to provide a guide for the latch, the second standard also serving as a vertical guide for the latch lift member.

With these and other objects in view, the invention consists of certain'novel features of construction, as will be more fully described, and particularly'pointed out in the appended claims.

. In the accompanying drawings Figure 1 is a side elevation showing my improved construction of carrier with a latch mounted to slide on the standards to control the let-off action of the package.

Figure 2-is a perspective View of the ten.-

- sion weight.

Figure 3 is a perspective view of the latch and the latchlift member.

'Figure 4 is a perspective view showing a tubular core on which the yarn mass may be carried, this core being provided with a ratchet toothed disc for engaging the latch to control the let off step by step.

- Figure 5 is a perspective view showing the weight and latch in raised position to permit the packagecarrier to be rotated.

, Figure 6 is a perspective view showing an auxiliary yarn package support adapted to be mounted on the package spindle, the lower. disc being toothed to engage the letoff latch and the upper disc having a stop pin to engage the teeth of the usual yarn package.

- Figure 7 shows the auxiliary package support as mounted on the package spindle and'supporting a yarn package.

It is found in practice of advantage, in some cases, to eliminate the usual pivoted stop pawl and slidably mount a let-off latch 00 on the weight and latch lift standards, whereby the latch is supported close to its engaging end to reduce the cramping action to the minimum so as to reduce the friction and wear and insure better operating results when the carrier is running at a high speed. It is also found in operating a latch of this character, in some instances, of advantage to provide a toothed disc on the yarn package having peripheral teeth adapted to engage this latch directly, While in other instances, it is found of advantage to provide an auxiliary package support, which is provided with a dischaving teeth to engage my improved form of latch and 76 also means for engaging the teeth of the usual form of package spool or bobbin having end teeth; and the following is a detailed description of the present embodiment of my invention showing one means so by which these advantageous results ma be accomplished.

With reference to the drawings, 10 designates the base of acarrier of my improved construction, the same being provided with a hub 11 supporting a package'spindle 12 on which is mounted a yarn package 13, and as illustrated in Figures 1, 4 and 5 this package is provided with a toothed disc 14 which is mounted on the core 15 .of the spool or bobbin. The base of this carrier isprovided with two upright standards 16 and 17, both of which are set on the major axis through the base which is substantially the center line through the long dimension of the quoit-engaging portion of the carrier, thereby obviating the necessity of making right and left handed carriers. Each of these standards is preferably of hardened steel and of small diameter with its lower end forced into the base. One of these standards 17 is of a height considerably less than that of the spindle 12 andits end is reduced and bent to form an open threadguide eye 18. The other standard 16 carries the tension weight ormember 19 which is mountedto slide vertically thereon, the weight being preferably struck up from sheet stock having a horizontal plate 20 with its sides 21 turned downwardly to form stop-engaging arms.

The plate 20 is provided with forwardlyprojecting fingers 22 arranged to embrace the opposite standard 17 to serve as a gu1de and prevent rotation of the weight on its standard.

In order to provide an elongated bearingfor this weight on its standard, I have formed an upturned portion having its end 24: turned inwardly. This end being pierced with a hole 25 in line with the hole 26 in its plate 20 to provide a double supporting bearing for the weight on its standard. This upper supportis also provided with a laterally extending hook-shaped linger 27 to serve as a thread guide around which the yarn is looped after passing through the eye 18. From this guide it is led up through the open guide eye 28 in the upper end of the weight standard 16.

Tension is applied to this weight by means of a light, coiled compression spring 29, the upper end of which passes through a hole 30 in the standard 16 while the lower coils are arranged to engage the inturned guide end 24: of the weight to apply the desired amount of tension thereto.

On these two standards 16 and 17 is slidably mounted a latch plate 30, the same bein provided with an inwardly extending raise% portion 31 forming a. latch tooth which engages the teeth 41 of the ratchet toothed wheel 14. This projecting latch tooth is preferably formed of sheet stock from the plate, which is first turned upwardly and then outwardly and one of the side walls of this latch is formed by turning the stock on one side straight down to form a square shoulder against which ratchet teeth ll will engage, while at the opposite side the wall is turned backward on an angle to provide an inclined face' as at 32 thus permitting the teeth 41 to ride under this pawl when the package is turned in a backward or counter clockwise direction to take up the yarn thereon.

In some instances it-is found of advantage to form the peripheral toothed wheel 1% on the spool or cop tube 15, which teeth are to directly engage the latch for the purpose of controlling the. let off of the yarn; while in other cases instead of forming a peripheral toothed wheel on the spool or tube, I provide an auxiliary package support 33, which has two spaced discs mounted on a short sleeve 34 which is adapted to be positioned on the package spindle, and on the lower end of this sleeve is fixed a toothed disc 35, the teeth'36 of which are adapted to engage the latch 31, while to the upper end of this sleeve is fixed a plate 37 which is provided with a pin 38 adapted to engage the end teeth 39 of the ordinary package spool 40 which may rest upon it.

My improved carrier is very simple and practical in construction and efiective in its operation and by my improved constructmn the effective working speed of the carrier, may be increased over that of the usual carrier of this character.

The foregoing description is directed sole- 1y 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 being defined and limited only by the terms of the appended claims.
