Referring more particularly to the drawings and the form of the invention shown in Figures 1 and 2, the numeral l designates a suitable supporting base and mounted upon the base at suitable intervals are supporting members i6 which extend transversely-with respect to the base, and any suitable number may be employed.

Mounted upon these members l6 and in suitable bearings are rollers i1 arranged in pairs and the rollers of the pairs are laterally spaced from each other to forma cradle for a tubular body portion I3 which rests upon the rollers.

This body portion is held against displacement in anydesired or suitable manner, such as by means of yokes or substantially U-shaped members l9 extending over the body portion with the ends thereof resting upon the respective bearing members l5 and which yoke members ii! are anchored in any desired or suitable manner.

The body portion I8 is hollow and one end center of the body portion I 8 with bearings 23.

Reel carrying cradles 24-25 are provided within the tubular body and each of the cradles 24 is provided with trunnions 25-21 and the cradle 25 is provided with trunnions 28-23.

The trunnions 23-21 of the cradle 24 are journaled inthe respective bearings 23 of the brackets 22 while the trunnions 25 of the next cradle 24 is journaled in a bearing 30 constituting a portion of an arm or extension 3| on the bracket 22.

The other end of this cradle 24 is journaled in the bearing in the next adjacent bracket 22 while the trunnion 28 of the cradle 25 is journaled in a bearing 32 of one of the arms or extensions 3I of one of the brackets 22.

The proximate ends of the first two cradles 24 terminate short of each other and a shaft 33 journaled in suitable bearings 34 extends across the space therebetween. This shaft 33 carries gears 35 which mesh with gears 35 secured to the respective cradles.

- mechanism 18.

head or end plate 2|. Projecting laterally from.

the head 2| is a trunnion 43 journaled in suitable bearings 44 and extending through a wall 45 in a casing 46.

Connected to the shaft 4| for rotation therewith is a sprocket gear 41 over which a drive chain 48 passes and which drive chain in turn passes over a sprocket wheel 49 on a shaft 58 of a variable speed drive mechanism designated generally by the reference numeral 5|, the latter being mounted upon a suitable portion of the base.

Rotation is imparted to the tubular body portion ill by means of a suitable driving motor 52 through the medium of a driving belt 53 which passes over a pulley 54 secured to the extension 43 of the head 2|.

Connected to this extension 43 for rotation therewith is a gear 55 which in turn meshes with a gear 56, which is mounted upon a shaft 51, the latter being journaled in a suitable bearing in the wall 45 of the casing 46. To this shaft 51 is connected a sprocket wheel 58 over which a sprocket chain 59 passes and this sprocket chain in turn passes over a pulley 68 that is connected to a shaft 6| of the variable speed drive mechanism 5|.

It will therefore be manifest that when the pulley 84 is rotated the extension 43 on the head 2| will be rotated and this in turn will rotate the tubular body portion I8. At the same time the gear 55 will be rotated and this gear 55 meshing with the gear 56 will through the medium of the sprocket wheel 58, chain 59, sprocket 68, shaft 6|, variable speed drive mechanism 5|, sprocket wheel 49, sprocket chain 48 and sprocket wheel 41, rotate the shaft 4| and with it the foremost cradle 24. This cradle will through the medium of the gears 36--35 and shaft 33 rotate the next adjacent cradle 24, both the cradles rotating in directions opposite to the direction of rotation of the body portion and at a different rate of speed with respect thereto.

Suitable openings 62 may be provided in the body portion l8 to permit access to the cradles.

The end cradle 'will be rotated independently with respect to the cradles 24 and to that end there is provided an extension or bearing 83 (see Figure 2) secured to and projecting laterally from the head or end 28. Secured to the trunnion 29 of the cradle 25 for rotation therewith is an internally toothed gear 84 with which a gear 65 secured to a shaft 88 meshes. The shaft 86 is journaled in suitable bearings 61-88 and projects beyond the end 28. Secured to the shaft 88 for rotation therewith is a gear 89 which meshes with the teeth of the internally toothed sprocket 18, the latter being mounted upon a bearing 1| that is secured, as at 12, to the extension 83 for rotation therewith, and passing 7 over the sprocket 18 is a sprocket chain 13 which also passes over a sprocket wheel 14 secured to a shaft 18 of a variable speed reduction gearing Motion is imparted to the sprockets 14 by means of a shaft 11 on which shaft is secured a sprocket wheel 18 and a sprocket chain 19 passes over the sprocket wheel 19 and also over a sprocket 88 secured to a shaft 8| of the reduction gearing mechanism 18.

The shaft 11 is iournaled in suitable bearings 82 and is rotated preferably by means of a gear '93 secured thereto and which gear meshes with a gear 84 that is connected with the gear 88 for rotation therewith.

It will be seen that when the pulley 88 is rotated the hollow body portion I8 will be rotated in one direction while the cradles 24 will be rotated in the opposite direction and at a different rate of speed with respect thereto. ,At the same time through the medium of the intermeshing gears 84-83, shaft 11 will be rotated and through the medium of the variable speed drive gearing 16, sprocket chain 13, sprocket wheel 10, gear 69, shaft 68, gear 85, gear 84, the cradle 25 will also be rotated and the rotation of this cradle 25 will be in a different direction with respect to the body portion l8 and at a different rate of speed with respect to such body portion and also a different rate of speed with respect to the cradles 24.

Carried by the bearing 1| is a frame 85 which is preferably secured to the lateral face of the bearing in any suitable manner to rotate therewith, such as by means of screws or bolts 99 and this frame projects for any desired or suitable distance beyond the bearing 1|. The frame is hollow and secured to the front end thereof is a die or nose plate 51 which may be removabiy secured in position by suitable fastening devices 88. this plate are arranged dies 89 through which the strands from the reels 98, which are carried by the cradles 24, pass. These strands are guided by suitable pulleys 9| supported by and arranged within the tubular body It at desired points.

Carried by the extension 83 on the head 28 is a supporting disc or member 92 having openings 93 therethrough, through which the wire strands pass and supported by the plate 92 are pulleys 94 for guiding the strands to the dies 89. This plate 92 may be secured in position by telescoping over a reduced portion 95 of the extension 63 on the head or plate 28 and rests against a shoulder 98 being held in position in any suitable manner such as by means of a fastening device 91 so that the plate or member 92 will rotate with the head 28 and the body I3 of the machine.

Supported by the trunnion 29, preferably by telescoping thereinto is a hollow shaft or tube 98 being held in position by a fastening screw 99, and is arranged to register with an opening )8 in the trunnion 29.

The reel |8| which is supported by the cradle 25 carries a preformed core and is paid out from the reel and passes through the opening I88 in the trunnion 29 and through the tubular shaft 98.

Supported by the free end of the shaft 98 is a housing I82 provided with a laterally opening entrance I83, and supported by one wall of the housing 82 is a die I 84 through which there is provided an opening I85 that is arranged in alinement with the opening in the tubular shaft 98. This opening I85 is shaped to correspond to the shape of the core and is preferably irregular in cross-section so that the core passing through the opening I88 of the die I 84 will, when the die is rotated, be axially rotated, as it is necessary in a machine of this character to rotate the core as the strands are being laid around it for the purpose of taking out the opposite twist or back turn as the strands are being laid around the core.

The frame 85 is provided with an opening I to permit access to the die I04 and the die I04 projects through the die or nose plate 81 and is encompassed by the dies or guides 88.

With this construction as the strands are being advanced and drawn together to be taken up by the haul-01f mechanism, the strands encompass the core.

Obviously any desired number of guides 88 may be provided according to the number of strands desired in the.finished rope or cable.

In the form of the invention shown in Figures 11 and 12 there is shown a different form of driving or actuating mechanism for rotating the cradles and consists of a sprocket wheel I08 se- 'cured to the trunnions 28 .of the respective cradles 24, and over each of which sprocket wheels a sprocket chain I09 passes. Each of these sprocket chains passes over another sprocket wheel |I0 secured to a shaft III for rotation therewith and which shaft III is housed within the body portion I8 to extend lengthwise thereof adjacent the inner periphery and which shaft is journaled in suitable bearings II2.

As the shaft M is rotated the first cradle 24 will be correspondingly rotated and through the medium of the sprocket wheel I08 secured thereto the shaft II I will be rotated by means of one of the sprocket chains I08. As the shaft III is rotated the remaining sprocket chains I08 will rotate the other cradles 24. I

In this form of the invention, however, the foremost cradle 25 is provided with. a separate driving mechanism so that it will be rotated at a different rate of speed from the speed of rotation of the cradles 24. To that end there is provided a shaft I I3 arranged adjacent the inner periphery of thehousing I8 and journaled in suitable bearings II4.

To one end of this shaft H3 is secured a sprocket wheel II5 over which a sprocket chain I I8 passes, and this sprocket chain in ,t-urn passes over a sprocket wheel II! that is secured to a tubular shaft 8' for rotation therewith. This tubular shaft I I8 passes through and is journaled in the end or head 43of the body portion I8 and projects beyond the end of the latter and also beyond the sprocket wheel 41.

Secured to the shaft M in this form of the invention is a gear II9. A supporting member I20 is mounted upon the shaft M for rotative adjustment with respect thereto and supports a gear I2I mounted upon a stub shaft I22, .These gears I2I-II9 mesh with each other and also with a gear I23 that is secured to an extension of the shaft 51, the gear I23 also meshing with .I24 in the supporting member I20 through which a fastening bolt I25 passes and which fastening bolt engages a stationary part of the machine.

The cradle 25 in this form of the invention is rotated by means of the shaft II3 through the medium of. a sprocket chain I28 which passes over a sprocket wheel I21 secured to the shaft H3 and a sprocket I28 which is secured to the trunnion 29 of the cradle 25.

The shaft II 3 is rotated as before stated through the medium of the chain and sprocket connection II5--II8-II'I.

It will therefore be seen that in both of the forms of the invention the cradles 24 as well as the cradle 25 will be rotated in a direction opposite to the direction of rotation of the tubular housing or body I8 and at different rates of speed with respect thereto and that the cradle 25 will also be given a speed of rotation different from the speed of rotation of the cradles 24 within the housing I8. i

With this construction the twist or back turn will be taken out of. the strands as well as out of the core as the strands are laid about the core and all of this is produced in a high speed machine, the preshaped core being carried by one of the cradles and is surrounded by the strands from the strand carrying cradles.

With this construction and by rotating the core as well as the cradles, some of the cradles rotating at a different rate of speed with respect to each other and with respect to the rotation of the machine, the lay of the strands in the finished product will be proper and accurate.

In the present exemplification of the invention the reel carrying cradles are shown as having a direction of rotation opposite to the direction of rotation of the machine or-tubular body; but it is to be understood that the cradles may be rotated either in such directionv or in the same direction of rotation as the machine or tubular body, and also that the foremost cradle may be rotated in the same direction as, or in a different direction from the direction of rotation of the cradles and at any desired rate of speed, with respect thereto.

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