  • the machine as shown and described here- V in consists of a series of what I term stranding units, the number of stranding units varying with the number of strands of which the cable is to be composed and, in
  • the machine shown in the drawing is adapted for making cable com osed of a core strand surrounded by a suita le number of outer strands. It is to be understood,
  • incorporation in the cable of a core strand is not essential to the operation of the machine nor to the structure of the completed cable.
  • the presence of a core strand is, however, usually desired, especially in a cable which consists of more than three or atthe mostfour outer strands, and
  • the machine includes for convenience in mountin the rotating parts a table 1 supported y suitable standards 2. 9n the table 1 are'erected a series of stranding units 3 of which that indicated by the letter A re 5 is a detached vieW,.showing the hollow spindle of the strandin" unit, the preother and therefore the 'core wiref together with the outer strands as they are successively laid may be drawn continuously through the spindles.
  • the core wire mechanism may consist of the core-wire supply reel 5 suit ably mounted by an convenient means and the drawin oif mec anism indicated by'the cipal function of the drawing-0E mechanismis to' maintain the core and cable under suitable tension and to move it at a speed coordinated with the speeds of the several stranding" units.
  • a suitable drawing-01f mechanism may consist of the pulleys 6 and 7, the ulley 6 being a drive pulley mounted. on a s ,aft 8, whichi in turn, carries beveled pinion 9.
  • the beve ed pinion 9 meshes with the beveled pinion 10 mounted on the shaft 11, which, in turn, carries the gear 12.
  • the gear 12 meshes with the pinion 13 mounted on the lay shaft 23, and, as will be obvious, rotation of the lay shaft causes the pulley 6 ed a sprocket 14, andon the shaft 15, which carries pulley 7 is mounted another sp1'o'ck-' et 16.
  • the sprockets are connected by an endless sprocket chain-.17'in the usual manner and consequently as the pulley 6 ro-' tates, the.pulley 7 rotates at the same speed.
  • the tension on the completed cable is created byopassing. it asufiicient number of times ut the pulleys 6 and 7, whereby suitable friction is caused. As the cable passes off the pulley 6, it may be reeled or disposed of in any desired manner.
  • bearing 21 supports journal 22 of the outer member 24 o a suitable draw clutch
  • journal being hollow and rotatable in the bearing 21.
  • the fact that the journal is hollow makes it adaptable also as one bearing for the spindle 3, the other bearing for the spindle 3 being the bearing 20.
  • On each of the hollow spindles are mounted two spools for containing a su ply of wire, one of which, namely, that indicated by the letter C, maybe termed the wire-supply spool, and that indicated by 'the letter D the reserve wire-supply spool.
  • These spools are, however, constructed in all substantial respects alike and; are interchangeable for the purposeshereinafter more particularly described.
  • FIG. 6 and 7 A detailed view of one of these spools is shown in Figures 6 and 7, from which it appears that it is composed of complementary parts, 25 and 26, which are adapted to be assembled on the spindle and secured to- "gether by engaging lugs 27 on the part 26 with the lugs 28 on the part 25.
  • Clearance indicated by the numeral 29 is provided to allowfor the interlocking of the lugs, and a slidable collar is mounted on the shaft and I cc is capable of being clamped in any desired position by means of-a set-screw 31. This collar serves to keep the wire-supply spools in position on the spindle.
  • the spool C when the spool C is free from wire it may be demounted by loosening the setscrew 31, movin the collar 30 along the shaft, then slipping the part 25 a sufiicient distance along the spindle to dlsengage the lugs, whereupon the spool may be removed from the spindle in separate halves. Thereupon the others 01 D, which may be assumed to i be fi led with wire, may be moved'up along the spindle to take the place of the spool G. The spool C may be then reassembled in place of, the spool f D whereupon it is in position to rece1ve wire in the manner hereinafter described.
  • a flyer Fixedly mounted on the spindle 3 1s a flyer, composed of arms 32 and 33, the arm 32 carrying the grooved rolls 34, 35 and 36, which serve to guide the wire from the wiresupply spool C in the proper manner and direction to be guided into the die or preformin nozzle which is hereinafter further referre to.
  • the mounting of the arms of the flyer may be accomplished by r gidly attaching them to the hub 37 which is apart of the bearing 38.
  • the hub 15 fixedly mounted on the spindle by any convenient means such as the key 39.
  • the bearing 38 also carries eccentrically mounted within it the helical die or pre-forming nozzle 39, which may consist of a rod of suitable material provided with a helical groove 40.
  • the other arm 33 of the fiyer carries a brake shoe 41 adapted to exert slight pressure ,on the arm of the particular spool of the pair which is delivering wire for the forming of the cable, that is, for example, in Figure 1 the spool C.
  • the motion of the spool C is therefore a resultant of two motions, one of which is the rotation of the spindle and the other is the rotation of the spool C on the spindle latter motion being determined by the rate at which wire is drawn through the pre-forming nozzle to be laid on the cable.
  • the reserve wire-supply spool D is normally fixedly mounted onthe spindle, this mounting, however, being through the medium of the clutch hereinbefore mentioned, which is preferably adapted to be automatically released at a predetermined time.
  • the clutch may consist of the outer member 24, which may be part of the bearing 22, the inner member 42 and the slide member 43 carrying the tapered rolls 44.
  • the clutch may be provided with a control lever 45 and.
  • the lay shaft which has driving connection with all of the stranding units as well as with the tensioning device, is indicated by the numeral 23. It carries gears 55, which, in turn, mesh with gears 56 mounted on shaft 57, which also carries the gear 58, so that the gears 57 and 58 rotate together.
  • the gear 58 meshes with the gear 59, which is rigidly connected to the bearing 22, and the gear 56 meshes with the gear 60, whirh is r1gidly mounted on the spindle 3.
  • the spool D 7 is rotated independently of the motion of the spindle, thus drawing wire from the reel 61 or from any other suitable source of su ply.
  • the clutch is released and the wire is cut.
  • the spool D is then ready to replace the spool C as soon as the supply of wire on the latter has become exhausted. In order to make rigid connection between the inner member of the clutch and the spools.
  • the inner member of the clutch is squared at the end as shown at 62, the squared end being adapted to fit a square mortise G3 in the spool.
  • the bushing 49 may e interposed between them.
  • the die or pie-forming nozzle 39 may. as above stated, consist of a rod provided with a helical groove of proper depth to accommodate the particular wire in use and of suitable pitch to properly pre-form the wire for the particular cable in process of manufacture.
  • the distance from the bottom of the groove 40 to the axis of the die determines the diameter of the helix formed and it is preferable that the diameter of this helix be slightly less than the diameter of the core wire, in order to insure that the former shall hug the latter closely.
  • the speeds of the various parts are coordinated with each other as accurately as possible; viz: the ratios of the gears which drive the fiyer and the reserve wire-supply spool are such that the wire-supply spool is certain to be filled in ample time in advance of the exhausting of the wire on the wire-supply spool G.
  • the speed of the tension mechanism is regulated by employing driving gears of suitable ratio to draw the core through-the several spindles at the proper speed to enable the outer strands to be laid closely and regularly.
  • the pitch of the pre-formmg nozzle is such that the helices thereby formed will be coordinated with the speed at which the cable is drawn through the spindles. All of these quantities vary, as will be readily understood, with the character of cable that is in process of manufacture, the principal determining elements being the number of strands of which it 1s composed and the pitch of the helices.
  • the preferred mode of op eration is to rotate the shaft 3 and consequently the reserve wire supply spool in a clockwise direction, the parts being considered as viewed from the position of the preforming nozzle. and in the direction of the clutch mechanism, that is to say, from right to left with reference to the drawings.
  • the preforming nozzle conseguently likewise revolves about the axis 0 the shaft 3 in a clockwise direction.
  • wire is drawn from the wire supply spool C, the latter rotates in a counter-clockwise direction with respect to the shaft, although its direction of rotation with respect to any fixed radius is of course in clockwise direction.
  • a left-hand strand or cable may, of course, be formed if desired by re-arrangement of parts such as is well within the, ability of the ordinary machinist.
  • I' h ave referred to the preforming member as a nozzle; It is to be understood, however, that the particular type of preforming member shown is a preferred form onl and that any other suitable device may e utilized for the purpose of bending the wire into suitable helical form...
