Application led August 24, 1923. SeraI No. 659,105.

To aZZ whom t may concer/rt: Be it known that l, FRANK MossBnRG, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Carriers for Braiding Machines, of which the following is a specication.

This invention relates to improvementsin lo the construction of braiding machine carriers; and has for its object to provide a carrier which is extremely light in v.v veight, whereby high-runningv speed may be obtained; and the carrier is provided with a is coiled spring acting upon the tension weight to accelerate its take-up action upon the yarn while the carrier is running at this high-rate of speed.

A further object of the invention is to 2o 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 va pair ot' cooperating standards on the carrier, one serving as a vertical lguide for the Weight and the spring for operating theI weight and the other serving to cooperate with the first standard to provide a lateral guide for the weight, the second standard serving primarily as a vertical guide for the lift member, which lift is also guided against lateral movement on the weight standard.

This invention further consists `in the utilizing of both of these standards as thread guides to cooperate with .the guidedon the4 bottom weight whereby the thread may bev readily passed into all of these open ended guides without being obliged toppass the 4o end of the thread through any of them.

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 '45 appended claims.

Itis found in practice of importance in order to obtain a high speed braiding machlne, to form the carrier as light as p0s' sible and to also provide means whereby the tension will act quickly to take up the slack in the yarn, also to set the weight standard and thelift standard on the longitudinal center line through the base so as to obviate the necessity of making right and left handed carriers; and the following is adetailed description of one construction of carrier by which these important results may be obtained.

\With reference to the drawings, 10 designates the base of a carrier for the usual guide 11 adapted to run in the usual raceway of a braiding machine, said carrier being provided lwith a hub member 12 in which is mounted a package spindle 13. This hub is pierced at 14 and the rock shaft 15 of the latch 16 is passed through this opening and a spring 1,7 is mounted to act upon this shaft so as to normally press the end of the latch perspective view of the` tenpackage spool 19. The opposite end of this latch is provided with a laterally extending member 2O to project beneath the package and be engaged by the latch lift 21. This lateral projection also serves to engage, lift and free the package it it should become stuck toits spindle or seat, and to also serve as a brake to prevent the yarn from overrunning.

On the top of this carrier, l have mounted two standard members 22 and 23, both of which are set on the major axis through the base, thereby obviating the necessity of mak- Each ot these standards is preferably -o small diameter' with its lower end forced into the hub 24 ot' the base. One of these standards being of a height considerably less than that of the height of the spindle 13, its end being guide 26.

- formed a sleeve 31 having a reduced lower- A tension weight or member 27 is mounted to slide vertically on this weight standard 22, the weight being preferably struck up from sheet stock having a horizontal plate' 28 with its sides 29 turneddownwardly to form stopengaging arms, the platel being provided with forwardly projecting fingers 30 arranged to embrace the opposite standard 23 to prevent lateral rotation of the weight on its standard.

In order to provide an elongated bearing for this weight 4011 its standard, I have end 32 which is forced into the plate 2 8, the upper end of this tube being also reduced at 33 to receive the'lower, closely wound 38 in the standard 22, while the lower coils are arranged to engage the neck 33 and give 'the weight the desired amount of tension.

In order that the upward stroke of this weight member when it reaches the desired height, may lift the latch and release the spool or package to rotate and let off more yarn, I have formed a latch lifting member 21, preferably constructed ofv sheet metal,

having a finger 39 extending into engagement with the lmember 2O of the latch, its rear end being notched as at 40 to engage and slide on the standard 22 thereby preventing lateral movement of this engaging linger. This finger is provided with' a hole 41 forming a lower bearing for the reception of the guide standard 23 and a widely spread upper bearing 42 is providedalso having an opening for the reception of the standard 23, and these lower and upper bearings are connectedby means of the connector mem ber 43 whereby this lift member is guided vertically on its standard. This upper bearing 42 is engaged by the lingers 30'on the weight to raise the latch lifting member to rock the latch on its shaft to release the package s'pool when more yarn is required.

into engagement with' the bottom of the spool to also lift and free it, thus preventing breakage of the yarn.

By my improved construction of carrier the cooperating parts are extremely light in weight ,and are'me'rely guided to perform their function withthe minimum amount of frictlonal resistanceethereby permitting the carrier to run at an extremely high rate of `speed and still operate to produce the desired results..
