Rv. oLsoN ET AL BRAIDER CARRIER Filed April 29, 1935 Patented Sept. 1, 1936 'UNITED sTATEs PAT'ENT OFFICE Mass.,
assignors to Mossberg Pressed Steel Corporation, a corporation of Massachusetts Application April 29, 1935, Serial No. V18,835 9 claims. (cl. 98-15) This invention relates to a braider carrier, particularly a carrier which is designed to run under very heavy tension; and the invention has for one of its objects the provision of means for preventing the package or bobbin from unduly lifting away from the feed control latch and thereby preventing an excessive let-off of the yarn from the package. o
Another object of the invention is the provision of means which acts as a stop limiting the upward movement of the bobbin or package and which can be readily disconnected and swung to such .a position as to permit of a fresh supply package on the carrier.
Another object of the invention is to secure all of the upright posts together for a more rigid support for the thread eye at the top of the carrier.
Another object of the invention is to tie together the upright post and bobbin spindle for a more firm support of the post and the thread guide eye which is mounted or connected therewith.
Another object of the invention is to provide the thread guide bail with .a connection at its top to the plurality of posts and to also cause this bail to tie in with the connection between the post and the spindle for making a rigid connection of the parts.
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 drawing:

In the running of braider carriers where a very heavy tension is employed, it sometimes occurs that the bobbin package due to this high tension is caused to lift away from the latch which controls the feed of the yam fromthe package and there is let off an excessive amount of yarn to the detriment of the action of the carrier. Also, the strain due to such heavy tension is not as well vsupported at the end of long or high posts due to vibration which may occur in the carrier; and in order to avoid these undesirable effects, we have secured together the posts and also connected the posts and the spindle for the bobbin package and have so arranged the securing means that it will limit the upward movement of the yarnor bobbin package so that it cannot disengage the 10 feed control latch; and 'the following is a more detailed description of the present embodiment of this Vinvention,:illustrating the preferred means by which these advantageous results may be ac- 15 complished:
lWith reference to the drawing, IO designates the base-of the carrier having quoit plate engaging surfaces I and 12 which are connected by a web |3 for'travel in theraceway provided in the bed plate, the gear engaging stud being designated |4. g Extending upwardly from the base of the carrier there is provided a spindle |5 upon which the bobbin or yarn package |6 with its'heads |1 and |8 is mounted. Head |8 is provided with a suitable ratchet formation 19 to be engaged by the latch 20 pivoted at 2| on the base and operated by the latch lift 22 which is guided by the post 23 land operated by' the tension weight 24 slidable on the post 25, the usual spring 26 forces the latch vlift 22 downwardly while the long acting spring 21 which encircles the post 25 engages the weight to force it downwardly in a known manner. Both the latch guide post 23 and the weight guide post 25-extend to a height substantially as high as th'espindleli. i f
The yarn 28 in'being drawn from the package |6, passes through the thread guide eye 29 which is mounted on the latch lift post 23 thence beneath the thread guide portion 30 of the tension weight and thence through the pigtail guide 3| mounted on the upper end of the latch lift guide post 23. The upper end of the posts 23 and 25 are connected together by a link 33 which is slidably mounted on the post 23 and is held by a threaded nut 34 and check nut 35 in engagement with the link 33, as more clearly shown in Figure 5. This link, of course, is urged upwardly by a spring 21 on the tension weight post 25.
A thread guide bail 36 for equalizing the yarn angle is suitably secured in the base as at 31 and passes through the link 33 where it is threaded and held on either side of the link 33 by nut 38, 39 screwed into firm engagement therewith. In this manner, the two posts 23 and 25 are firmly ecured together at their upper ends while the thread guide bail 36 is also secured thereto, thus forming a rigid support for the upper thread guide 3|.
A sleeve 40 closely slidably fits the post 25 above the tension spring and is provided with a member 4| extending upwardly as at 42 thence horizontally as at 43 and bent to form a clip as at 44 to resiliently detachably engage a groove 45 in the end of the spindle 46 so that this member 4| may be swung about the post 25 as a center to and from engagement with the spindle 46 while its horizontal portion 43 which extends over the top'of the bobbin package will effectively prevent theV package from rising on the spindle to an extent to become disengaged from the latch 2'0 and allow undue rotation of the let-off of the yarn.
The resilient portions or jaws 41 and 48 extend a little more than half-way around the circumference of the recess 49 so as to gripthe same against accidental swinging of the parts away from engaging position. i
In Figures 6 and 7 we show a different or modified construction in which the link now designated 50 is provided with a bore 5| for pivotally mounting the member 4| and in this case the tension spring 21 contacts with the under surface of the link, although the link is prevented from movement by the nuts 38 and 39 on the bail. i In this case, however, the changing of tension Springs 21, it'is merely necessary to remove the nut 39 and disengage the member 4| when the link may be slid upwardly to permit removal of the spring and replacement of a spring of different tension. The stop or retaining member 43, however, will function as before even though the point of pivoting is slightly different in the modified form.
The foregoing description is directed solely towards the construction illustrated, but we desire it to be understood that we 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.
