As best seen in FIG. 1, the divider blades 21 are spaced apart to form therebetween tum-receiving gaps 31 in which are positioned turns of insulated conductor wire forming coils 32 the side turn portions of which are to be received in the axially extending slots 33 of a core such as that shown at 34.

  • the slip clutch 50 ties the actuators 29 and 38 together for concurrent longitudinal or axial movement so long as both are free to move. However, if one of the actuators, such as actuator 29 for instance, is restrained from movement, the mechanism 50 will slip so that the other actuator, such as actuator 38, may move axially relative to the first one.
  • the inner actuator 38 extends beyond the slip clutch mechanism 50, and its lower end is provided with a lock nut 51. As best seen in FIG. 3, a relatively long portion of actuator 38 adjacent its lower end is provided with threads 52.

  • a lock washer 66 is threadedly received in the upper end of the pistons 65 so as to be slidable about actuator 38 but to be in overlapping or interfering relationship with lock nut 51.
  • a lock washer 67 is firmly connected to the outside of the upper end of piston 65.
  • a lock plate 68 is mounted to the underside of drive plate 63 by means of bolts 69 so as to closely surround piston 65 and overlie lock washer 67.

Such a construction will allow initial adjustment of the stop members 71 to compensate for tolerances of various other of the components to provide the proper insertion stroke.
  • the bolts 69 further serve to attach a cylindrical insulator drive member 74 to the upper side of drive plate 63.
  • a number of insulator pushers 75 are firmly attached to the upper portion of the drive member 74 and are spaced circumferentially about the drive member.

  • the insulator forming mechanism may be of any conventional construction, many of which are known in the art and thus, for the sake of simplicity and ease of understanding, the details of such a mechanism have not been shown herein. It will be understood that at least in the final position of the magazine 76 and preferably in each of its positions for receiving insulators the guide apertures 77 are aligned with the guide apertures 16 for transfer of the insulators from the magazine through the apertures 16 into a suitable magnetic core.
  • a core securement means which in the exemplification takes the form of a pair of latches or dogs 78 which are mounted to elongated actuating rods 79.
  • the rods 79 in turn are received in double action actuating cylinders 80 which move the rods up and down (as seen in FIG. 2) between a position engaging the upper edge of a core such as 34 and a position spaced above the core.
  • the latches 78 When spaced above the core, the latches 78 may be swung out of interfering relationship with the core to the position shown in FIG. 1 so that a finished core may be removed from the apparatus and a new core placed over the divider blades 21 until it comes to rest on the top surface of the insulator guides 13. Then the latches are swung back into an interfering relationship with the core and the cylinders 80 actuated to retract the rods 79 until the latches 78 engage the outer periphery of the core.
  • FIGS. 2 and 3 together illustrate the positions and interrelationships of various components of the apparatus just prior to the insertion operation.
  • the insulators 78 have been formed in the predetennined insulator guide apertures 77 of the magazine 76, core 34 has been placed over the distal end of divider blades 21 so that the teeth forming the axial extending slots 33 rest on the upper ends of the insulator guides 13 and the latches 78 have been pulled down against the upper side of the core to hold the core against axial movement.
  • the insertion operation is provided by actuating drive cylinder 70 to move piston 65 in an upward direction (as seen in FIGS. 2-7).
  • the apparatus moves from the position shown in FIGS. 2 and 3 to the position shown in FIGS. 4 and 5.

  • the drive plate moves insulator drive member 74 and thus insulator pushers 75 to move the insulators 78 out of magazine 76 and up to a position just under the coils 32.
  • the first portion of the movement of piston 65 ends when drive plate 63 engages the base 54 of control member 53 (as seen in FIG. 5).
  • control plate 49 and thus the actuator 29 and divider blades 21 are restrained from any further axial movement relative to the core.
  • Continued movement of piston 65 causes the drive plate 63, acting through the insulator drive member 74, to drive the insulator pushers 75 and concurrently therewith, acting through control member 53, actuator 38 and head 36, to continue movement of the feeder blades.
  • the slip clutch 50 allows relative movement between the actuators 38 and 29 so that the actuator 38 may move axially while actuator 29 is maintained stationary.
  • FIG. 7 The relationship of the components at the termination of the insertion operation is illustrated in FIG. 7 wherein it will be noted that the distal ends of the turn feeder blades have moved through the divider blades to insert the coil side turn portions into the axially extending slots 33 of the core 34, and the insulator pushers 75 have moved the insulators 78 out of the insulator guides 13 and into the axially extending slots 33. It will be noted that in this position the teeth 56 of control member 53 and teeth 58 of the cup like member 57 are intermeshed but do not quite touch. This interfitting relationship interlocks the control member, i.e., connector device 53 and the stop device formed by plate 49 and member 57, for adjusting the apparatus for cores of different stack heights without causing any binding of the parts during the insertion operation.

  • the core 34 may be removed from the apparatus by actuating cylinders 80 to raise latches 78 which are then rotated out of interfering relationship with the core. Then the core may be manually removed from the apparatus. It will be understood that, while the insertion operation has been described by reference to portions of the movement of the piston, in normal operation piston 65 travels from its position in F 1G. 3 to its position in FIG. 7 in one continuous movement.
  • the apparatus may be returned to its original position for subsequent insertion of coil side turn portions, and insulators if desired, by actuating cylinder 70 to move the piston 65 in the other axial direction (that is down as seen in FIGS. 2-7 During its return movement the drive piston 65 will retract drive plate 63. After a first portion of the travel of the piston 65, the lock nut 66, attached to the end of piston 65, engages the lock nut 51 attached to the lower end of actuator 38. Further movement of the piston 65 causes retraction of the head 36 and thus turn feeder blades 35.
  • the slip clutch mechanism 50 functions during the retraction stroke to carry actuator 29, and thus divider blades 21, with actuator 38 until flange 28 engages plate 11 to halt actuator 29. Thereafter clutch mechanism 50 allows actuator 38 to move relative to actuator 29 as drive plate 63 is retracted by piston 65. The retraction operation ends when piston 70 completes its return or retraction stroke.

  • the space between the top of control plate 49 and the bottom of stationary plate 46 is sufficient to allow the divider blades 21 to move through the bore of core 34 during the first portion of the increment of movement of the feeder blades.
  • the control member 53 is set so that, betweenthe position at which drive plate 63 engages the control member, base 54 and the position at which the tops of stop member 71 engage the underside of control plate 49 to halt the movement of the piston 65, the actuator 38 will be moved a sufficient distance to move the turn feeder blades through the divider blades, in their extended position, to insert the coil turn side portions. Also, the setting of control member 53 determines the distance the insulator pushers 75 are moved before the turn feeder blades begin to move so that the insulator pushers will move the insulators from the magazine to a position just behind the coils. Thus, the coils and insulators are inserted into the axially extending slots of the core in the proper sequence as the divider blades and insulator pushers thereafter move simultaneously.
  • FIGS. 8 and 9 illustrate the apparatus adjusted to insert the side turn portions of coils 32a into a core 34a having a minimum stack height within the predetermined range of stack heights.
