Abstract

This is an assembly tool for wiring magnetic core planes (lower right). Although the cores are numbered, when a plurality of windings is made, the number is obscured leading to mis-wiring.

This is an assembly tool for wiring magnetic core planes (lower right). Although the cores are numbered, when a plurality of windings is made, the number is obscured leading to mis-wiring.

The device comprises a tape recorder 10 carrying the instructions, a keyboard 11 having a key corresponding to each core position, a jig 12 for holding the plane P and two grids 14 and 15 each containing contacts aligned with each core position.

A plane P is placed in the jig 12. A key K1 closes the circuit for the recorder which instructs the operator as to size and length of wire to be used. One end of the selected wire is fastened to the frame of the jig by tape and the other is threaded on a needle 17.

The jig is now rocked to the left until microswitch SW1 closes again operating the recorder. The latter now tells the operator the number of the core to be wound, e. g., core 21. The operator then depresses the jig further to open SW1 cutting off the recorder. This action closes microswitch SW2 providing a circuit to magnet 18 which holds the jig down against the action of spring 20.

The operator now closes key 21 and inserts the needle through the core 21 to effect a junction with contact 21 in the grid 14. This completes a circuit from 0 v A. C. through key 21, contact 21 in grid 14, needle 17, jig 12, relay R1, contact of SW2 now closed to 6 v A.C. operating relay R1. R1 opens the circuit for magnet 18 thus releasing the jig which is moved to the position...
