PLAITING-MACHINE.

Application led October 7, 1918. Serial No. 257,088..

will be relatively simple in construction and `positive and eii'cient in operation.

- to this particular form, inasmuch as changes Special objects are to improve-the carrier structure and the mechanism for im arting 'the necessary plaiting movement to t e 'car-l rieis; to provide simple and effective means Afor automatically controlling the feedingof the separate strands from vthe moving 'carriers to the'condenser, and to provide improved lmeans for drawing off and reeling up the product.

Brieiy .stated ,the invention resides 1n the combination of a plurality of carriers travcling on intersecting or connecting tracks,

with means for propelling said carriers along said tracks, and means in the nature of traveling switches for shifting the carriers alternately from one track to the other.`

-The carriers are of special construction, as will appear as the specification proceeds,

4and the other features of the invention such as the take-up and the reeling mechanism all will be fully considered as-the specification proceeds.

In the accompanying drawings, I have illustrated the Ainvention as embodiedin a` practical commercial form, but. it will. be understood that the invention is not limited and modifications may be made without departure Afrom 'the true spirit and scope of the invention.

Fig. 6 is a vertical sectional view of the gearing and transfer mechanism taken substantially on the planeof theline'G-v--GV of .Fi 3. y

renerally speaking, the machine consists ofa bedl or table 15 supported on a suitable base or frame 1.6' and provided with tracks" or run-ways for the carriers 17 which carry the strands 18, said strands meeting atthe Patented Feb. io, 1920. y

condenser 19, from which the product is ,drawn off by the take-up rollers'20-2l, the

finished plaited cord 23 -beingthen woundl on a vreel 24.

The carriers travel on intersecting or connecting paths having the general configuration ofa figure 8. The outline of such paths is wellv illustrated in Fig. 3 wherein it will be seen that the lbed plate is formed with two substantially circular openings 25 and 26 therethrough, the periplieries of such openings meeting or overlapping-.S as indi. 4

cated at the point 27 to provide the intersection or connection between the paths for the transfer of the carriers from one end to the other of the`figure 8 path-way.

Operating in the circular openings 25 and 26 in the bed plate are the sprockets'28 and 129, said sprockets having thel reduced rim or flange portions 30 and 31 respectively, overlapping'at the point of intersection of the two paths, as indicated, and provided with registering equi-distantly spaced pockets or'recesses .32 ,therein to. receive corre-y spondingly spaced studs on the carriers'.

The carriers, as shown in the drawings, consist of spaced top. and bottom plates or slices 33 and 34 held in vertically spaced relation by the connecting studs 35 which have portions 36 dependent beneath the bottom shoe 34 for engagement with the switching mechanism to be described. They .upper shoes 33 bear on top of the sprockets and the Y upper surface of the bed plate, and thelowei' shoes 34 are disposed' beneath the sprockets andthe under surface of the bed plate, while the studs or pins 35 work in the pockets 32 in the rims of theV sprockets.

In the construction illustrated, the sprock i ets 28 and 29 are carried by the tubular shafts'37 and 38 journaled on the supporting posts or Astuds 39 and 40 disposed concentrically within the circular track op.en 4ings 25 and 26 and mounted 'on the transverse bracket 0r base plate140. vThese tubular Sprocket shafts as clearly shown in Figi 6, are gea-red to rotate in unison by intermeshing gears "ll and ,42 fast on said shafts. In the case shown, power is applied to the sprocket-s by means of a. shaft irprovided with, fast and loose pulleys -ll-l5 thereon and carrying on its inner end a initcr gear 46 in mesh with a miter gear 'i7 on the lower end of the sprocket shaftv 3 8. n

The carriers are transferred alternately from. one path to the other by traveling switches or transfer devices shown in the form of segmental guides 4t8-49-50 and 5l. These transfer segments are shown as disposed concentric to the two sprocket centers (sec Fig. 5) and are shown as carried by the disk-like supports 52-53 which are `connected together so as to rotate in unison by means of the gears {i4-55 to whichy said segment disks are `fastened. The gearing and arrangement of these transfer segments .furthermore is such that in, the rotation of said parts the segments will pass the point' of intersection of the two carrier` paths alter- `arrangement of the transfer segments is -clearly illust-rated in Fig. 5. v

'1 he purpose, of the transfer serments at each side of the point of intersection of the carrier paths is to take hold of the carriers as they approach the -point of intersection or connection and transfer them alternately to the opposite sides.

studs or projections 3G which extend down far enough below the lower shoes of the carriers to be engaged by the transfer' segments. A

, In order that the .transfer devices may overtake the carriers and draw them over to the oppositeA paths from which they are traveling, said segincnts'are caused to rotate two transfer devices 52, 53 being geared t0` gether will rotate at equal s iced, but said transfer devices by reason o4 the speed-up gearing described will .rotate at greater linear speed than the sprockets.

ln the particular machine herein shown, there are live carriers, cach sprocket is equipied with live pairs of equl-distantly `spaced propelling pockets and there are four as transfer segments, two associated with each nately from opposite sides. This alternative Engagement with the carriersisell'ected by nieansoffthe dependent will rotate at equal speed and likewise they sprocket. The gearing is proportioned 'so that lthe transfer devices will make five complete revolutions to every four complete revolutions ofthe sprockets. As a result of this, the transfer segments will continually overtake and transfer the carriers alternately to the opposite paths, and the proper timing of theparts will he continuously maintained.

'lo make the transferring action clear, I. have indicated the carriersl 17 in Fig. 5 in dotted lines'.y In this view,the-partsvrotat ing in the direction of the arrows, the segrnent 49 is shown as having overtaken and transferred a carrier from the right hand path-way over'to the left hand path-way, and the segmentV 50 is 'shown as about to overtake and pass? behind the,leading pin 36 on the carrier approaching the point of intersection from the left hand side.y As the' segment 50 overtakes and passes behind the leading pin 3G. on the carrier a recess or cut-out 58 intermediate the en of the segment receives the second pin of the carrier, and in the further acceleration of said Segment passes behind the second pin, the segment thereby gainingy hold on both the carrier-pins an drawing said carrier over so as to` carry both pins into engagement with the driving pockets in the rim of' the right hand 95 sprocket. In corresponding fashion the left Yhand transfer segment 48 will overtake and transfer the carrier shown in the right hand corner of the figure, as such carrier approaches the point of intersection of the two paths, transferring the same over to the left l hand sprocket. The transfer devices thus alternately approaching the point of intersection from opposite sides serve to vtrans'- fer the carriers alternately to the opposite sprockets. v y

In view of thel fact that the propelling pockets in the overlapping rim portions of thesprockets register at they point of connection of the two paths, the/segments need 11ol not actually shift 'the carriers laterally to any appreciable extent, as the simplynced to pass behind the pinsvof the carriers to confine them to the pocketsin the proper sprockets until after the point of intersection has been passed, whereupon the carriers will-be retained in engagement with such propelling-pockets by ybeing guided in the tracks provlded in the bed plate. vThe segments therefore, are active only at the point 120.

of intersection of the two paths and are then merely called upon to guide the/carriers- .sufliciently to insure their engagement and retention by the proper sprockets.l

To prevent premature shifting ofthe carriersfrom one sprocket yto the other, I have shown a control device in the form of a yielding switch 59 pivoted in the bed plate 'at 60 and normally retained in an intermediate position by the springs 451. This hold! 13o ing device Vfits into the cut-away portion 62 provided in the overlapping rims of the two sprockets, and by engagement with the dependent studs of the carriers serves to hold said carriers engaged each with their propelling sprockets until the point is reached where the segments gain controlof the carriers to shift them from one sprocket to the other. 4

The tracks in the bed platefor guiding the carriers, may be cut down into the bed plate as indicated at 63 in Fig. 6, for the purpose ofbetter guiding the carriers, the adjoiningportions of the sprockets being correspondingly cut down as indicated at 61 to form a complete guiding channel re- 'ceiving' the upper shoe portions of the carriers.

v The condenser 19 where the strands are collected is located directly above the point of intersection or connection of the two tracks or substantially above the center of the figure 8 design, by reason of which the carriers as they'pass in alternation in reverse' directions, lay the strands lone over the other into a substantially flat plaited cord. The pitch or vangle of the overlay may be varied b' v adjusting the condenser towardl or awayrfrom the carriers, for which purpose the condenser is shown .carried by an arm 65 having a vertical sliding adjustment over a rib or track 66 on the post or supporting column 67, said condenser arm being secured in its` adjusted position by means of a set screw 68. l

On the forward or leading end of the carrier is mounted an upstanding post 81 Afor carrying the strand tensioning and slack take-up devices.

The plaited product after leaving the condenser passes betweenthe drawing o rollers 20-21 which are shown as beingpositivelyv driven for the purpose of taking the cord from the condenserv at a predetermined speed. One of lthe rollers, the upper one 21, is shown journaled in the end of 'a link 97 pivotally supported at 98. This permits the separation of the rolls by. simply lifting the upper roll. The upper roll may be re tained in its lifted position by means of the pivoted link 99 which is slotted to slidingly engage overvthe pin 100, the slot in said link being formed'with a shoulder 101 at the lower end thereof so that upon lifting v,

the roller this link may be shifted slightly 'to engage the shoulder over the pin 100A whereupon the' link will support the upper roll in its liftedfposition. upper roll is shown provided with agear102 arranged to mesh with the 'gear 103 of the lower roll,

this latter gear being engaged in turn byv the gear 104 to which is connected a sprocket 105. 'A sprocket chain 106 I engages lwith said sprocket and passes 'over another sprocket 107 onthelbase of the machine.

i at 128 an This latter sprocket is connected-with a gear 108. which is in mesh with a gear 109, and

.gear 109 is connected with a worm gear 110,4

which meshes with a corresponding worm gear lll-driven by gear 41 on the sprocketl shaft 37. This provides a simple positive drive from one side of the sprocket shaft. The reeling mechanism is drivenvfrom the opposite side ofl the sprocket shaft, the s means for this purpose consisting of al Worm y gear 112 in'mesh with the opposite side of the worm gear 111, and drivinga gear 113 connected by gears 114 and 115 with the reel shaft or spindle '116.

lThe reel 24 for the finished product is- 80 coupled to the support-ing spindle therefor in such a way as to compensate for the variations in diameter as the cordis wound thereon. l

Another feature of the invention is a special form of traverse consisting of a lever 127 pivoted on the base of the machine lprovides the necessary gearing' ratio and provides .a quiet smooth drive for the travers'e. The traverse lever 127 is guided and held forward in proper engagement with the cam by means of the forwardly projecting, track 137 over which said lever has a sliding bearing.
