This spring 61 is tensioned prior to connecting the cable 45 to the pulley 42 so as to exert a constant pull or tension on the pulley and cable to prevent the cable from developing slack or becoming tangled during the operation of the unit 19.
  • Bell crank is pivotally supported for vertical swinging movement at 68 upon an existing shaft 69', FIGURE 5, of the machine.
  • the bell crank 68 carries on its horizontal arm a lifting roller 69 engaging a bottom cam 70 of the vertically shiftable lifter rod 15, the latter having guided engagement through opening means 71 in the spindle rail 11.

  • adjacent lifter rods and their lifting bell cranks 68 and 70 are linked together by horizontal connecting rods 71' connected to the respective bell cranks, as shown.
  • Weight levers 72' carrying weights 73 are carried by the rock shafts which support the lifting bell cranks 68 and 70'.
  • the weights 73 counterbalance the weight of the ring rail 14 and lifter rods 15 and normally bias the ring rail towards the elevated position shown indotted lines in FIGURE 1 and shown diagrammaticallyl in FIGURE 2. This construction is all conventional and need not be dealt with in further detail.
  • the cable 45 which is a single cable leading from the single unit 19 is connected with only one quadrant 67 at the top of one lifting bell crank as illustrated.
  • a limit switch 72 for limiting the upward travel of the ring rail 14 is suitably mounted upon the top of casing 20 or in any other preferred manner close to the adjacent end of the ring rail 14, and with its actuator 73 in the path of travel of the end portion of the ring rail 14.
  • a second switch 80 preferably a roller-actuated micro-switch or the like, is xedly secured at 81 to the forward side wall of casing 20.
  • the switch has an upright plunger 82 carrying an actuating roller 83, spring-loaded upwardly to bear against locking pin eX- tension 52 and to ride over a shoulder 84 on plunger 53 when such plunger moves inwardly under influence of spring 56, as when the pin extension 52 enters the locking notch 51.
  • the switch 80 is a normally closed switch, whereas the switch 72 is normally open and is a time delay switch which will remain closed for a minimum of one minute, while the ring rail 14 is being lowered, and then reopens automatically.
  • the switch 80 When the shoulder S4 engages roller 83, the switch 80 will open to deenergize electric clutch 32 at the moment when the pin extension 52 and the disc 50 lock the ring rail 14 in the lowermost or dofng position, as will be further described.
  • the switch 8i) is closed when the roller 83 is on the pin extension 52 and while closed maintains the clutch 32 energized or active.
  • a plug 85 is provided for connection with a source of ll() volt alternating current.
  • This plug is connected by a wire 86 with a suitable rectier 87, and from the rectifier another wire 88 leads to and is connectedv with one terminal 89 of the clutch 32.
  • a wire 91 leads to and is connected with one terminal of the upper limit switch 72.
  • a wire 92 leads from the other terminal of switch 72 and is connected in series with one terminal 93 of switch 80.
  • the other terminal of switch 80 is connected with a wire 94 leading back through the rectifier 87 to the plug 85, thus completing the circuit through the electric clutch and the two switches 72 and 80 connected in series therewith.
  • the ring rail 14 With the spinning frame in full operation for spinning the yarn and filling the bobbins 13, the ring rail 14 will be elevated to a position well above the lowermost doiling position shown in full lines in FIGURE 1.
  • the front draft roll 18 is revolving continuously, as is the shaft 31 connected with the front draft roll through the gearing 1S.
  • the clutch shaft 28 is also revolving due to the continuous meshed engagement of the gears 30 and 31.
  • the switch 72 is open because the ring rail 14 has not yet reached the uppermost extent of its travel and the clutch 32 is de-energized or inactive, and no rotation is imparted to the shaft 37 and pulley 42 during the normal operation of the spinning frame for winding the yarn upon the bobbins, under control of the conventional builder motion, not shown.
  • the clutch 32 is de-energized or inactive
  • the ring rail 14 reciprocates vertically through relatively short strokes and each stroke of the ring rail commences at a slightly higher elevation relative to the bobbins than the last preceding stroke to provide the well-known filling wind on the bobbins. During this gradual rising of the ring 'rail 14, the same does not influence the limit switch 72,
  • the ring rail 14 When the bobbins are full, the ring rail 14 is at the uppermost position shown dotted in FIGURE 1 and also shown in FIGURE 2, and the ring rail now engages the actuator 73 of normally open switch 72 and immediately closes this switch to complete the circuit through the terminals of the electric clutch 32, the switch titl now being closed which is normal for this switch.
  • the electric clutch 32 is now energized and continuing rotation of the shaft 23 through the energized clutch imparts identical rotation to the shaft 37, pulley ft2 and locking disc Si?.
  • Rotation of the pulley 42 now winds up the cable 45 in a controlled manner and causes the bell cranks 68 and 7G to swing counterclockwie upon their pivots or supporting shafts against the action of the weights 73', and this effects the lowering of the lifter rods 15 and ring rail i4 at precisely the desired rate of speed, which rate is predetermined by the chosen diameter of the pulley working face 46.
  • the electric clutch 32 remains de-energized during the next ycomplete spinning cycle and until the ring rail again fully rises and engages switch actuator 73 to close switch 72 and reenergize the clutch 32 to again being the controlled lowering of the ring -rail 14 toward the dofling position.
  • the locking pin extension 52 does not re-enter the notch Si until the ring rail again reaches the dotiing position, and in this connection it must be understood that the eX- tent of linear movement of the cable 45 is relatively small to effect the desired lowering of the ring rail, and the pulley 42 carrying the disc 50 turns through only one complete revolution, so that the notch 51 ldoes not repeatedly pass the pin extension 52 during the cycle of operation.
