frames, after which the strand passes back l inOsthe-f longitudinal center of the frames and outwardlytherefrom to suitable .guides on the main-frame These guides are disposed near thekperiphery or outer edge of the main frame andinv longitudinal alignment thereon so that .y the strand passes in a direction parallel with the axis-of the frames, after which it is led back into the longitudinal center of the frames and outwardly therefrom to a wind-up bobbin. In this manner .alltwist or turning of the cable ceases sov that the-completed strand may be drawn oil! and wound upon a. suitable wind-up bobbin.

fMoreparticularly, the outer or main frame is indicatedat I0. This frame is of elongated rectangular shape having end members II and I2 each provided with outwardly extending longitudinally vdisposed hollow trunnions I3 and Il mountedl for free rotation in fixed bearings I5. Thev second or intermediate frame or carriage is (indicated at I6 and is likewise of elongated rectangularshape and of a size to freely rotate within. themainfframe I0. The end bars of the intermediate frame are indicated at I1 and I8. The end bar I8 has afllxed thereto a centrally 1ocatedtoutwardly projecting hollow trunnion I9 lvlwhich` rotative bearing ingan adjacent bar 20 ofthe mainframe and in the longitudinal axis of thelatter. The opposite end bar I1 of the second orV intermediate frame has likewise alxed thereto anoutwardly projecting centrally disposed hollowtrunnion 2| having rotative bearing in an adjacent bar 22 o! the main frame. From this construction it will be seen that the main or outer frame isfree to rotate upon a horizontal axis in thebearings I5, while the second or intermediate ,i frame I6 is -free to rotate upon and within the mainframe and in the same longitudinal axis thereof? I,

`'IflieAzhircl or innermost frame 23 is also of elongated. rectangular shape and is rotatably supt' ,portedglwitnln the intermediate frame ls. This frame is provided with ond bars 24. fromlone ofv which projects a stub shaft 25 dis- 5 posedfin'the longitudinal axis of the frame to militanti s111190 me end therf' The opposite l .-iendsliiau"y 2l.v of the said innermost frame has rigdlyzi thereto an outwardly extending centrallyfdisposed hollow trunnion 21vpivotally supporting the said end in the adjacent cross bar 28 of the. intermediate frame I6. A

outer end of hollow trunnion I3 which I l supports the ymain frame I0 has aiixed thereto a pulleyd over which passes a drive belt 30 leadmi any suitable source of power. Rotatably supported upon the trunnion I3 is a gear 3| aiiixed against rotation by a pin 32 which anchors the gear to the bearing member I5. The gear 3| is in mesh with a gear 33 mounted upon shaft 34 having bearing in the end member II of the main frame. This shaft 34 has bearing also in the bar 22, and afnxed to this shaft 34 is a gear 35 in mesh with a gear 38 ailixed to shaft 31 havlng bearing in the hollow shaft 2l. The inner end of shaft 31 has aixed thereto a gear 38 in mesh with gear 39 carried by stub shaft 49 having bearing in adjacent bars of the intermediate frame I8. 'I'he shaft 48 has secured thereto a gear 4| which is in mesh with an intermediate gear 42 rotably carried by the second or intermediate frame I in the bar 28 thereof, and the intermediate gear is in mesh with a spur gear 43 alxed to the outer end of a hollow trunnion 44 projecting from one end of a haul-oi! drum frame 45 disposed longitudinally within the innermost frame and near one end thereof. This haul-off frame is disposed in the longitudinal center of and is therefore coaxial with the other frames. The opposite end of the haul-off frame has projecting therefrom a hollow trunnion 45 mounted for rotation in a cross bar 41 in the innermost frame. This hollow trunnion has affixed thereto a conventional twister die indicated at 48.

The haul-off frame carries a laterally disposed shaft 49 to which is afllxed the haul-off drum 50. One end of the shaft 49 has afllxed thereto a worm wheel 5I in mesh with a worm 52 carried by shaft 53 mounted in a suitable bearing 54 on the haul-off frame. 'Ihe shaft 53 has aflixed thereto a spur gear 55 in mesh with a gear 58 mounted loosely upon the hollow trunnion 44 and secured against rotation by a pin-51 which anchors the said gear to the cross bar 24 of the innermost frame.

The hollow trunnion 2| which rotatably supports the intermediate frame I5 has afxed thereto a spur gear 58 which meshes with a gear 59 amxed to shaft 34.

The innermost frame 23 carries a desired number of rotatable supply bobbin frames 88, three being shown in the present instance. These frames are oi' elongated rectangular construction and are mounted within the innermost frame to rotate upon axes parallel to the axis of the said innermost frame. Each of the supply bobbin frames has a hollow trunnion 5I at one end rotatably mounted in a cross bar 62 of the innermost frame, while the opposite end of each of the vsupply bobbin frames has affixed thereto an outwardly extending trunnion 63, each having amxed thereto a spur gear 84 in mesh with a master gear 85 vrotatably mounted in the intermediate frame and axially thereof. This master gear 55 is provided with a hollow central shaft 55 to be rotatably received upon the trunnion 25 ailixed to the innermost frame end 24. The hollow trunnion 85 is provided with a spur gear 91 in mesh with a gear 88 amxed to shaft 89 mounted for rotation in cross members constituting a part of the intermediate frame I5. The shaft 59 has another gear 18 alxed thereto which is in mesh with a gear 1| secured to a hollow shaft 12 rotatably mounted in the hollow trunnion I9 of the frame I5 and in the longitudinal axis thereof. 'nie outer end of this shaft 12 has affixed thereto a gear 13 which is in mesh with a gear 14 affixed to a jack shaft carried by the main frame and rotatable upon an axis parallel with the axis of the frames. The shaft 15 projects beyond the end of the main frame III and has secured thereto 4 a gear 18 in mesh with a gear 11 loosely mounted upon supporting trunnion I4 of the main frame. The gear 11 is secured against rotation by a pin 18 which passes through the gear as well as through the bearing post I5.

The shaft 89 has also aiilxed thereto a gear 19 which meshes with a spur gear 19 secured to trunnion 25 of the innermost frame 23.

Each of the supply bobbin frames 98 is provided with a freely rotatable bobbin 8|, from each of which a wire 82 is led through the hollow trunnions 6| in convergence in the twister die` 48, at which time the several wires are twkted together as a strand or cable. This strand, indicated at 83, passes over the haul-oil drum 50 and out through the hollow shaft 44. A guide roller 84 mounted in the axis of the intermediate frame I9 receives the strand, from whence the latter passes laterally to a guide 85 disposed near the outer lateral edge of the intermediate frame I6. The strand then passes rearwardly of said frame and parallel to the axis thereof to a guide 8B also carried by the intermediate frame, from whence it passes back into the axis of the frames to the guide roller 81 carried by the intermediate frame. The cable or strand then passes through the hollow trunnion 12 to a guide wheel 88 secured to the end member I2 of the main frame III and in the longitudinal center thereof. From the guide roller 88 the cable passes laterally of the main frame to a guide 89 carried by the said frame near an outer lateral edge thereof, from whence the cable passes forwardly of the said frame to a guide 90 also carried by the main frame and in longitudinal alignment with the guide 89. The cable then passes radially inward of the main frame to the guide roller 9| carried by the main frame and disposed in the longitudinal center thereof, from whence the cable passes through the hollow trunnion I3 to a suitable or orthodox wind-up bobbin, not shown.

From the foregoing, it is apparent that rotation of the pulley 29 by means of the belt 30 will cause the main frame I9 to rotate in one direction while the second or intermediate frame I6 will rotate in the opposite direction. Due to the gearing arrangement, the speeds of rotation of these frames will not be the same, and it will be understood that the gear ratios may be changed as desired to obtain the desired relative speeds of these frames. Rotation of the pulley 29, which is affixed to the outer frame I9, will cause the latter to rotate. The gear 33 travels in planetary action around fixed pinion 3|, causing shaft 34 to rotate and through gears 59 and 59 causes the intermediate frame I8 to rotate in a direction opposite to the direction of rotation of the outer frame. A the same time, the gear 35 drives gear 35 which in turn rotates gear 38 which is in mesh with gear 39 carried by shaft 48. The gear 4I upon shaft 49 drives intermediate gear 42 which is in mesh with gear 43, the latter being alxed to the hollow shaft 44 which connects with the haulofl.' frame (viewed from the right end in Fig. 1) 45. Rotary movement in the latter, as well as the twister die 48 connected thereto, is thus obtained, while at the same time the planetary movement of pinion 55 upon fixed gear 58 brings about driving action of the haul-off drum through the instrumentality of the worm 52 and worm Due to the manner in which it is mounted, it is obvious that the innermost frame 23 will remain stationary while the intermediate frame I5 rotates about it. The spur gears 54 secured to the stub shafts 63 of the supply bobbin frames travel around gear 65, thus bringing about rotative movement of the supply bobbin frames.

As the wires 82 converge in the twister die 48 it is turned, for instance, in clockwise direction, while the intermediate frame I6 is turning in the same direction but at a ratio, say, one to four. As the twisted cable passes centrally or axially to the frame I6 it continues to rotate in a clockwise direction. The cable or strand passes laterally of the frame to the outer edges thereof, Where it is now turning anti-clockwise, whereupon it takes a rearward course to the opposite end of the frame, being led to the axial center thereof at said end. At this point the ratio is now one to two. As the strand then passes from the longitudinal center of the frame outwardly to the guides at the lateral edges of the main frame, the latter turning counterclockwise, (viewed from the right in Fig. 1) it is making but a single turn. As the cable passes forwardly of the main frame and out through the center of the pulley 29 it is not turning at all, and may be wound up on a suitable windup drum. It will be understood that changes in the sizes of the various gears may be resorted to to bring about desired results without departing from the spirit of the invention.

It is obvious, however, that by removing all twist or turn in the cable issuing from the machine, the wind-up operation is greatly simplified.

The machine here shown, and for example only, is provided with three supply bobbins, but it will be understood that more may be added as required. The bobbins here shown are dis.- posed in radial arrangement within the bobbin supporting frame, but it will be understood that this arrangement may be departed from should it be desired.
