  • Patent number: 4917318
    Abstract: A winding apparatus for fabricating a multifilar low voltage winding for a toroidal transformer is disclosed. The apparatus uses a wire storage magazine 18 and a wire winding shuttle 20 which rotate about a semitoroidal winding mandrel 38 to wind a multifilar low voltage winding 48 on the winding mandrel having a greater radial depth of turns at the radially inward leg of the winding than at the radially outward leg of the winding. The multifilar winding can be wound with a group of conductors in a single pass over the winding mandrel, or wound one conductor at a time using multiple passes over the winding mandrel, or wound using multiple passes over the winding mandrel with some intermediate number of conductors being wound during each pass.

  • Patent number: 4884758
    Abstract: Apparatus for winding a continuous length of wire about a mandrel to create coils of wire uses a coil winding machine having a circular cage mounted to a frame and a circular winding magazine freely rotatably mounted to the frame within the cage to define an annular cavity between them. Initially a supply of wire is wound on the magazine, such as counterclockwise. The wire on the magazine continues to be connected as a continuous strand to a large, external spool of wire. A winding shuttle is driven along the annular cavity clockwise to remove wire from the magazine and wind it about a mandrel. Wire is removed from the magazine at double the rate at which it is wound about the mandrel. The excess wire initially expands within the cavity. The expansion is halted by the cage. Once all of the excess wire is restrained by the cage, the continued clockwise movement of the shuttle causes the excess wire to double back upon itself in a loop so the wire is rewound on the magazine in the clockwise direction.

  • Patent number: 4771957
    Abstract: A winding apparatus and method for fabricating a multifilar low voltage winding for a toroidal transformer is disclosed. The method and apparatus use a wire storage magazine (18) and a wire winding shuttle (20) which rotate about a semitoroidal winding mandrel (38) to wind a multifilar low voltage winding (48) on the winding mandrel having a greater radial depth of turns at the radially inward leg of the winding than at the radially outward leg of the winding. The multifilar winding can be wound with a group of conductors in a single pass over the winding mandrel, or wound one conductor at a time using multiple passes over the winding mandrel, or wound using multiple passes over the winding mandrel with some intermediate number of conductors being wound during each pass.

  • Patent number: 4343386
    Abstract: An actuator ball movement coordinator and cam member for a torque responsive hub clutch of the ball and cam type serves to assure coordinated movement of a plurality of actuator balls and also cams the balls into positions which cause actuation of the clutch.

  • Patent number: 4262785
    Abstract: A clutch interposed between a hub mounted for rotation on a spindle and a selectively driveable axle which extends longitudinally through the spindle serves to engage the hub to the axle when the clutch is subjected to torque caused by placement of the axle in a dynamic or driving axle mode. When the axle is in a passive or non-driving axle mode the clutch serves to disengage the hub from the axle whereby the hub is free-wheeling on the spindle.
