12 Claims. (Cli 7 96-15) This: inventionrelates: to a ,braider; carrier and has for oneof its, objects to provide a quick and positive; acting latch release for the braider bobbin.

Anotherobject. of the invention is simplicity of adjustment of tension applied to the latch that. variation: in such tension may be readily effected.

.Another object: of the invention is the simple and quick; adjustment of a compression spring encircling azrod or. part.

Another object of" the invention is toprovide spring tensionin the carrier so arranged that.

centrifugal. force; of the carrier when moving about the braider machine; will have little or no effect: on the tension. which the spring applies.

Another. object ofthe'invention is the provision: of an. easy acting latch release whereby the action of the yarn in causing such release will-not be subjected to an abrupt increase in tensionupon it. I

Another object of theinvention is to provide asimple and effective means wherebythe spring which acts upon. the weight may be easily andquickly changed for one of different-tension if desired. T H

.A further object of the invention is to providezan arrangement of structure whichmay be easilyfassembledor. disassembled for cleaning. and

yet one the'parts of'which are-securely held in place..when-.assembled. v V 7 With these and. other objects in view, the invention consists of certain novel featuresof constnucti-on, as. will be morefully. described, and

particularly pointedout in the appended claims.

pentine;- pathway of a braider machine are continually moving; tow rdzandiromthe cent r; f;

the machine to which the yarn carried by the; carrier is dispensed. Accordingly, it becomes" necessary for permitting this varying movement. toward and from the work center and yet main- ..tain tension on the yarn which from the stand:-

point of good work should be, maintained. conpentine pathway;

stantly' tensioned. The carrier must also; beof. such character that it may operate at a relatively high rate of speed as the efficiency of: the

q machine depends on the speed of the carrier Carriers also travel about the machine at suchratethat centrifugal force plays some part in-v the operation of the parts; and inorder to'provide anarrangement with spring tension such; that the spring tension will not be affected by centrifugal force and also to provide for a quick;,; accurate, sensitive latch release which may be easily adjusted, I have provided a newway of pivoting the latch release and tensioning the; same in an arrangement whereby the release of the latch may take, place gradually or with--- out that sudden jar usual. in braider carriers; also, I have provided a. simple and efficient'means-g for-changing the spring on the weight which, is utilized on the carrier; and the following:- is. a more detailed description of the present embodiment of this invention; illustrating the pre ferredmeans by which these advantageous results may be accomplished: I

vWith reference to the drawing, IE! designates; generally the base of a carrier consisting of thev flanges H and 12 extending from the web l3 which. travels in the slot .inthe bed plate ofthe; machine for guiding the carrier through itsser [4 designates the horn'by which the carrier is driven. A package spindle. designated generally I5 is'cast integrally with the, baseand extends upwardly therefrom. This spindle has a base portion I6. which is cut away. as at I! and which provides a shoulder [8 above which is the upper smaller portion IQ. of the spindle. The shoulder l8 limits the insertionv of the. package onto the spindle for determining its bottom position. A hub 25;] also is cast integral with the base and provides a bottom mounting for a pair of spaced standards 2l and. 22, which extend upwardly from. the base and. are joined by a ,block, 23 which is secured in positionby a pin 24 passing throughthe blockand;

.also. located in a recess in the standard H as.

Th latch is designated generally 25 and is shown in perspective in Fig. as having an upstanding tooth 26 with an inwardly sloping angular end 21, shown in Figs. 1 and 2. The lower portion 28 of this latch is turned at right angles as at 29 to extend beneath the fulcrum projection 30 on the base N5 of the spindle, although any convenient point for mounting a fixed member with which this latch may engage as a fulcrum may be used. The latch is guided in its desired vertical movement between a pair of pins 3| and 32 projecting upwardly from the base It].

A latch lift member 33 is provided with a pair of ears 34 and 35 which slidably engage the pin 36 projecting upwardly from the base, while the arm 31 of this latch lift member has an opening 38 for pivotal attachment to th latch through hole 39 in the latch by a pin 39 which has its opposite ends enlarged to provide heads although permitting free rocking movement of the latch with relation to its lift member. A spring 39 encircles the pin 36 and forces the latch lift member upwardly. This spring is held under compression by .a spring clip 43 which may be adjusted along the length of the pin 36 to any desired height by simply inserting a screw driver between its outwardly extending ends and spreading the same to release its grip on the pin 36. In this way a very quick adjustment of the tension of the spring may be had. This spring will of course affect the yarn tension during latch release. It will be readily apparent that as the latch lift member is moved upwardly, it moves the latch upwardly into engagement with the teeth of the bobbin to prevent rotation thereof. The angle of the latch end 2? permits quick release as a movement about its pivot 39 to the extent indicated in Fig. 2 will release the tooth from the bobbin.

A tension weight designated generally 42 is slidable upon the standards 2i and 22 and by gravity will drop to the lowermost position on these standards in which position its stop arm 43 will engage the stop levers of the machine and stop the machine when this weight is in lowermost position. A spring 34 assists the movement of this weight in lowermost position and engages a hook 45 at the upper end of the weight and a hook it which is wrapped around the standard 22 and is swingable about this standard 22 in an arc of substantially 90 for unhooking the end 47 of the spring and replacing this spring with one of different tension when required.

The hub 20 has a bore 48 in which thereis vertically slidable a latch release rod 49 which also slidably extends through bore 53 in the block 23, this end of the release rod being somewhat enlarged to provide an enlarged bearing as at 5|. An L-shaped lever 52 is pivoted as at 53 upon the pin 24 and has a cam surface 54 in the path of an arm 55 secured to the weight, while the. other arm 56 of this lever engages the upper end of the latch release rod 49 just described.

The latch 25 has a laterally extending arm 51 with a slot 58 and shelf 59 whil the release rod is bent outwardly as at 60 to enter this slot 58 and bear upon the shelf 59 so that when this rod is moved downwardly, it will have an enlarged bearing for movement of the latch to release position.

The weight carries the hook 62, while the standard 2! carries pig-tail guide eyes 63 and 64. Yarn being led from the supply package will pass through the guide eye 63 beneath the hook 62 and then upwardly and out through the pigtail guide eye 64 to the maypole of the braiding machine; as the yarn is used up, the weight will be lifted or the weight will drop to take up slack until a time when more yarn is needed when the arm 55 will engage the cam surface 54 of the bell crank lever 5| to depress the latch release rod which will in turn bodily depress the latch letting off more yarn, thus letting the weight drop and latch move back into locking position as shown in Fig. 1.

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.

I claim:
