16Claims.

This invention relates to improvements in high speed stranding or wire rope machines of the floating cradle type either of a built up or tubular construction, and one oi the objects of the invention is to provide in a machine of this character improved means for causing themae chine to rotate in one direction and the cradle to rotate in the opposite direction and at a slower rate-of speed, whereby the opposite twist or back turn may be taken out of or created in the rope or cable.

A further object is to provide improved means for guiding the wires and improved means for threading the wires into the machine. To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention, and in which Figure 1 is a view in side elevation, partly broken away, of an improved machine of this character constructed in accordance with the principles of this invention.

Referring more particularly to, the drawings, the numeral 20 designates generally a tubular body which may be of any desired length and diameter and is provided throughout its length with cut away portions 2| to permit access to the interior of the body and. to me mechanism contained therein.

Encompassing the body at predetermined points throughout its length are rim members 22 which constitute means for rotatively supporting the body and to that end there is provided a supporting base 23 suitably mounted and upon which base is arranged supporting rollers 24, forming a cradle in which the rim members rest. The rim members are of an internal diameter greater than the external diameter of the portion of the body surrounded thereby, so as to provide a space therebetween into which a wedged fastening element is forced to anchor the rim to the body as shown more clearly in Figure 16. Anchor members 25 of substantially U-shape formation may be provided for holding the body portion against displacement during the rotation thereof. 1

These anchor members pass over the rim members 22 and may be secured in any suitable manner by their ends, by means of fastening devices 26 which also engage the supporting base 23.

If desired, a brake member 21 may be provided for controlling the rotation of the body member.

Within the body 20 is arranged a series oi'v cradles 23 in whichthe wire reels 2! are mounted.

These cradles are spaced from each other in directions lengthwise ofthe body and the proximate ends of. adjacent cradles are disposed in proxim ity to each other.

Arranged within the tubular body are bearing.

32 carried by a shaft 33 which latter is jour-' naled in the bearing and is laterally ofl'set with respect to the axis of the gears 3| and the pivots of the cradles 28. One of the gears 3| is provided with an opening'therethrough so as to permit the wire from one of the reels to be threaded therethrough.

Also arranged within the body 20 is a supporting member 34 which encompasses a bearing 35 in which adjacent ends of cradles 22 are also pivotally mounted. The supporting member is of a diameter somewhat less than the internal diameter of the body portion 2| so as to form a space between the periphery of the member 34 and the wall of the body.

I The peripheral edge of the support is prermeans for the adjacent portion of the wali of the Tire wedge shaped members 21 may be held in position in any desired or suitable manner, such as by means of fastening bolts as and the entire, structure embodying the member 3. and the wedge shaped member 21 may be secured against longitudinal displacement in any suitable manner.

Any number of these structures may be provided throughout the length of the body and any number of supporting bearings may also be provided. 7 I

These structures are provided within and ad- Jacent the encompassing band or rim 28 and cooperate therewith for maintaining the body against distortion and for bracing. the same.

As will be seen from Figure 4, the rim ll is of an internal diameter substantially greater than the external diameter of the adjacent portion of the body and are held in position by a wedge shaped element forced into the space between the body and said rim.

The body is adapted to be driven from any suit-- able source of power with a pulley 4| on its shaft. Over this pulley 4| passes a driving belt which in turn passes over-a pulley I secured to the body 2| for rotation therewith. The end of the body 20 is preferably provided with a closure 'or end member 44 of any suitable construction and carried by this end member I is a trunnion II which is journaled in suitable bearings It in a housing 41.

Secured to the trunnion I! and between the end member H and the housing 41 is a pulley l3 and this trunnion is preferably joumaled in roller: bearings 48.

Secured also to the trunnion 45 for rotation therewith, and within the housing 41 is a gear 49 which in turn meshes with a gear 50 carried by a ranged within the body 20 and one end of the shaft is connected to one of the cradles '28.

- Thus it will be seen that when the pulley 42 is rotated the body 20 will also be rotated and the mechanism is such that it will be rotated at a high rate; of speed. The shaft 51 is driven from the body portion 20 by means of an intermediate driving connection which is such as to rotate the cradle to which the shaft 51 is connected in a direction opposite to the direction of the rotation of the body 20 and ata slower rate of speed.

The intermediate gear and shaft connection ii, 22 and 88 between the cradles willaiso cause them to rotate in the same direction and at the samerateofspeed asthedirection andspeedof rotation-of the cradle to which the shaft '1 is directly connected.

The wires as they pass from the reels and through the pivots of the reels, also pass over guide pulleys I0, and in the form of the invention shown in Figures 1 and 4 also pass through the rim members II and are brought together at the opposite end of the machine so as to pass through a die or nose plate and from there they are led to the drum or draw off mechanism.

I: desired, additional guide members 0| may I be provided on the outside of the body through which the wires may pass. These guides ll may be of any desired configuration but are preferably in the form of loops having a slot 82 therethrough arranged at an angle to the longitudinal axis 'of the body portion so that in order to insert, the wires into the guides and loop, the wires must be twisted and held at an angle. This will prevent accidental displacement of the wires. I

Suitable guidepulleys 62 may also be provided adjacent the end of the body where the wires are directed to the die or nose piece 80.

Another form of guide for the wire is shown in Figure 8 at N and comprises a hook shaped body having a spring tongue or member 65 forming a closure therefor.

As shown in Figure 9 of the drawings tubular members 06 may be arranged along the outer periphery of the body 20 which pass through the rim or flanged members 22 and through which tubular members the wires from the reels are Guided.

In Figure: 15 similar tubular members 61 are provided but these members 81 are arranged on the inside of the tubular body 20.

The wires may be initially threaded through these tubular members in any desired manner such as by means of a piston member 68 of a size to fit within the tubular member 86. The piston is provided with an eye 69 to which one end of a wire 1. is connected.

This piston 38 is adapted to be inserted in the tubular member 66 and a blast of air is directed into the tubular member 66 against the piston .8 from a tube1i on one end of which is provided a nozzle 12. This nozzle is split as at 13 so that 60 the wire will enter thereinto when the nozzle is inserted in the end of the tube 66.

Thus when a blast of air is forced through the nozzle 12 it will strike the piston 88 and force it.

through the tubular member 68, carrying therewith the end of the wire 10.

In the form of the invention shown in Figure 9 the cradles 14 are mounted for free swinging movement and the axes of the trunnions 16 are disposed between the axes of the pivots of the ends of the cradles and the cradles are provided with open bearings 15 to receive the trunnion or axle 16 of wire reel 11. A locking member 18 passes through the walls of the bearing above the trunnion 18 for locking the wire reel into the cradle. This member 18 is adapted to be operated by means of a handle 19 and withdrawn against the stress of a spring 80 to permit removal or insertion of the reel 11. If desired, a locking screw or bolt 8| may be provided for maintaining the locking member 18 against accidental displacement.

Motion may be imparted to the draw on drum or mechanism by means of a shaft 82 journaled in suitable bearings extending lengthwise of the machine and which shaft 02 its motion by means of a gear 83 meshing with a gear 84 that is carried by the shaft Ii.

With this machine and when it is desired to 5 manufacture an ordinary rope or cable, the cra- 1 chain connection I2 may be released with respect to the shaft 5|, and a locking device may also be provided for holding the shaft 51 against rota-' tion. Any suitable locking device may be provided such as a pin 83 adapted to be inserted through 5 an opening in the sprocket wheel 56-A and into rotated at a high'speed and the cradles will be rotated in the opposite direction and at a slower rate of speed.

The pivots or supporting ends ,of the cradles are spaced from each other so as to permit the wires to be threaded through certain of the pivots and this is accomplished by offsetting the shafts 33 so as. to provide a gear connection around the pivots of the adjacent ends of the cradle members.

While the preferred forms of the invention have .0 been herein shown and described, it is to be understood that various changes may be made in the details of the construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the a spirit of this invention.
