BRAIDER CARRIER Filed May 6, 1939 IlllullL ATTORNEYS.

Patented Aug. 13, 1940 BRAIDER CARMER Robert V. Olson, Attleboro, Massy,- assigncr to Mossberglressed Steel Corporation, a corporation of Massachusetts Application May G, 1939, `Serial Noli-72,134)

9 Claims.

This invention relates to a braider carrier and has for one of its 'objects to provide an improved connecting link at the upper ends of the guide standards carried by such brader carrier.

Another object or" this invention is to provide a connecting link at the upper ends of the guide standards of a braider carrier which will maintain these guide standards so that their axes are parallel through their extent at all times and prevent any weaving to and fro of such guide standards. even though heavy tensions are used l in the operation of the carrier.

, Another object of the invention is to provide guide standards which will permit of a free operation of the tension weight and braider machine stop which slide along the guide standards and which will he deferred from free operation should a weaving or bending movement of the standardsoccur to move their axes out of parallel relation.

Another object of the invention is to provide a connecting link between the guide standards of a braider carrier and yet permit easy removal of the parts carried or guided by the guide standards, thus making it unnecessary to remove the guide standard for the removal of such parts carried or guidediby it.

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

- In the use of a connecting link such as shown,

(ci. semis) inthe Mossberg Patent 1,970,390, the connecting link is, so mounted upon the longer of the twol guide standardsv with raised projection to limit its movement, that if the thread-eye, the latch lift, or itstension spring, are desired to be removed, it is necessary to remove the guide standardy for the removal. Further, there is nothing to prevent the weaving or moving oi the rods out of axial parallelism; that is, their upper ends may Weave or swing when heavy tensions are em-` ployed, thusY Adeterring the desired free operation oi" the tension weight or sometimes referred to as the Iii-raider machine stop andin order to avoid these undesirable eiiects, I provide a link which may be easily lifted and swung from position or which may he slid completely from the longer of the standards leaving an unimpaired uniform diameter' ci guide rod for the removal or the parts carried hy this longer guide standard and I also provide such an arrangement that relative rotation oi the linkin one of the guide standards," primarily the shorter guide standard, cannot occur, thusl maintaining the desired axial parallelism of the standards throughout their length, and the foliowing is a more detailed description of the present embodiment of this invention, ilustrating the preferred means by which these'advantageous results may be accomplished.

With reference to the drawing, li designates the basefof'the carrier with the package spindle ii extending upwardly therefrom. The yarn package 'shown inY dotted lines at l2 is controlled by the latch i3 in a usual manner. A longer guide standard it and a relatively short guide standard i5 extend upwardly from the base iii, providing a means for mounting the yarn thread-eye it and guide iorthe latch lift il with its tension spring it, also for mounting and guiding the weight or i3-raider machine stop i9 and its tension spring Eil.

At the upper ends of these rods ill and i5 I provide a'connecting link designated generally El .shown in perspective in Fig. 3, comprising a portion 22 of sufficient size to have an opening 53 inwardly from its periphery into which another part in the form ci a brushing or sleeve 2i?. may extend to provide an increased bearing vby extending as at 25 below the portion 22 for embracing and sliding along the longer guide standard iii..` An opening 2t is also provided in this portion 22 which is shown as square in cross-section, altho any section out of round may be provided. y 1

Thisfopening 25 receives the reduced square end 21 of the guide standard l5 which is of a size .and shape to' .closely nt the opening 2t and as this squared end 2'I is of a size smaller than the diameter of the standard I5, shoulder 28 will be provided so as to limit downward sliding movement of the link 2| on the standard I5 or on the standard I4. A spring 29 is positioned on the standard I4 above the link where it abuts the pigtail guide 30 and tends to force the link downwardly against this shoulder as a stop. This spring 29 will be of a tension greater than the tension in the spring 20 so that the link may form an abutment for this spring 20. If it is desired to remove spring 20 to change it for a spring of diierent tension, it is merely necessary to slide the link upwardly into the dotted line position shown in Fig. 1 and swing the link to one side about the rod I4 as an axis, remove the spring 20 and replace it with another, and then swing the link back permitting the squared section 2'I to enter the square opening 26 and move until the shoulder 28 is engaged to limit the movement of the link under the action of the spring 29.

If it is desired to remove any of the parts carried by the standard I4, it is merely necessary to remove the pig-tail guide 30, slide the tension spring 29 and link upwardly from the rod I4, thus leaving standard I4 free at its end to have the parts carried and guided by it passed over this end, thus making it unnecessary to remove the rod I4 from its position.

In Fig. 5 I have illustrated a modification in which the upper end of the rod I5 is tapered as at 3| and the opening 32 in the link 33 is tapered to nt this opening. This taper is a frustro-pyramidal shape in both instances whereby relative rotation of the parts is prevented and a downward limit of the movement of the link is provided.

In Fig. 8 a simple form of reduction is provided. Here the rod I5 is reduced in circular form as at 35 and the link 26 is also provided with a circular hole 3'I to receive it. In this form the relative rotation of the link and standard I5 is not prevented.

In Figs. 9 and 10 the link 38 is shown as provided from a piece bent U-shape having an upper plate 4I and a lower plate 42 with a connection 43 between them, also a standard encircling sleeve 44- for embracing the guide rod. The end of the standard I5 is permitted to remain in its formed round cross section throughout its extent and the link 38 is provided with a cup 39 to set into the upper plate 4I and provide a recess 40 for the reception of the end of the standard I5 whereby the movement of the link along the standard I5 is prevented. In this case, also, I have not shown any means of preventing relative rotation of the link and the short standard, although clearly this might be provided. A different form of abutment to limit the movement of the link along the standard I4 is shown.

It will be apparent from the above that various arrangements may be provided to limit the movement of the link on the guide rod and also to prevent relative rotation of the parts as between the squared sections mentioned above.

From the various forms above shown it will be apparent that I may freely remove the link from the standard I5 by lifting and swinging the same or the link may be removed from the standard I4 by the removal of the tension spring 29 and the pig-tail guide 30. A stop is provided between the short standard and the link in such a manner that when the link is removed, the

standard is free to permit of the tension spring or any other part guided or carried thereby to be removed.

The foregoing description is directed solely 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 dened and limited only by the terms of the appended claims.

I claim:
