speed by the'two toothedpinions 8 Beit known thatI', JEAN'BRONDEL, a citizen of the .French Republic, residing at Lyon, in France, have invented a certain new and useful Improvement in Machines for rthe Production .of Tubular Plaits, of which the following'is a specification. y

The object of/rthe present invention is` av4 he threads 2, 2, from the inner bobbixis 4 always retain the same direction, but the.: threads 3, 3 from the outer bobbins 5 compelled to pass first below the bobbing@- as shown at the leftgof Fig. 1 and then above 60 said bobbin as indicated at the right of `said Q figure. The threads may be caused tochan Y t eir direction each time they encounter one of the bobbins 4, or when they encolii'ltegf` the either withoutla core -for example for use as lacing cordsor inclosing a tubular or any other form of core, for mstance an yelectric:

' conductor. A plaiting machine includes essentiallytwo series of bobbinsrotatingin opposite.

directions concentric'ally about'a core, and in sucha manner 'that the threads of one series of bobbins pass alternately above and below the threads of the otherseries.

They machines employed hitherto manipu- -late the threadsr composing the plaits by means of mem ers'having alternating or nature of the` plait. The threads 2 'act as warp threads. It will beunderstood that 'f the plait can thus be regularly'formedf parts. v

The drawings show by way of example a "i54 'device suitable for eifecting this guidance.

anism and limits thespeed to a low rate.

these two members belng secured ltogether 80 by bolts 1,3, and having between them an V undulating slo-t 14 (Figs. 1 and 2), formin a passage for the threads 3 from the bobins 5. By following and being guidedA in said slot 14 the threads 3 are caused to 85 pass alternately below and above the bob bins 4. lo prevent obstruction or hinf" drance to said threas they may be causedfto effecting the operation or movement of the traverse vertical glides 21 secured to thev rotary plate 7. I ompensating spring`22 90 is provided to insure constant tension on the' tgrammatically suliielent of the improved threads 3,

machine for comp ehension of the inven- 40 tio,`-Fi ure 1 being a vertical section through t 1e axis of the machine. and Fig. 2

a section on the line A-A of Fig. l.

he core l ofthe plait passes vertically through the' center of the apparatus at a uniform` speed. The single or multiple threads 2 2 and 3, 3, which form the plait are unwound from two series of bobbms 4 and rotating i'n opposite directions around sai-d corel. l e said bobbins may be Iont any suitable number such as eight, and are mounted at or adjacent the circumference of two circular plates 6 and 7 given movement in opposite direct-ions andat the same rotary movements f or operating the central by small slides 15 `which run in a circular undercut groove or guide 16 'formed in thel cup 12 and intersecting the undulating slot 14 s as to pass alternatelv above and below 100 saidslot. A

Each slide 15 carrying one ofthe bobbins 4 v1s carried around by the plate 6A b means of two disks 17 the perip eries ot w ich exbeing continuously rotated by means;V

respectlvely keyed 011 the driving shaft 10. `-55 second or third bobbin, etc., accordingto'the 65 the weft threads and the threads 3 as the'. i

tend intoV two grooves in t 1e slide, said disks 1'0'5 -toothed pinion I8, intermediate gear 19 and -slide .'15 one' of said disks continuing the movement ofthe bobbins 4 during the passage of a thread 3 through the notch of the other-` disk.' I l Instead of mounting the two disks 17 on- 'the same axle below the bobbin 4, it may be desirable in certain cases to mount them one l.below and the Aother above said bobbin, the

slide 115 beingmodiied accordingly. This arrangement will increase the security of 'the guidance by separating to a greater extent th'esuccessive periods of release of the disks. The path for the slides 15 could also 'be located' on a frame inside or between the bobbins 4 which arrangement would decrease the 'length of path traveled by said h' any other suitable mechanism ments of the slides without changing the relative move- I other members. It will be understood that the actuation of therotarydisks and plates may be produced than that wn f' and described.

What I claimas my invention and desire to secure by Letters Patent'of the United States is In a, plaiting machine, guideway, a bobbin ca mounted therein, with grooves, notched disks adapted to extend within said grooves, a support `for said disks, means for moving said support whereby said slide guideway and means for rotating said disks,

during Jthe movement f said support, the

in combination, a ing slide movably 'notches 1n said disks being out of lregistry said slide being provided` will be moved 'along said with oneanother whereby when'the notch in either disk registers with the associated groove in said sllde the other disk will be 1n operative engagement with its associated groove, thereby providing for .a continuous movement of the slide.
