Cable Forming Method

The formation of hand-wired cables for large circuit gates is expedited and accuracy is improved by using indicating lamps to assist an operator.

A fixture 1 supports a plurality of dummy circuit boards 2, 3, 4 and 5 to simulate a circuit gate. Each dummy board temporarily holds terminal combs 6, with each comb-carrier having a plurality of teeth corresponding to the actual terminations on the boards. Each comb can be identified by an indicating lamp
7. The teeth on each comb have a common color-code and uniform sequence, such as three red, three blue, etc., and each of the teeth for a comb is represented by a lamp on one of the banks 8, 9 of lamps at the fixture top. Each group of lamps in the bank is correspondingly colored. At the left of fixture 1 is a compartmented holder 10 for wires to form the cable. Each compartment 11 contains supply wires of a different length and can be identified by a lamp 12.

Cables are formed by using a deck of cards and card reader 13 which is controlled by the operator. When the card reader 13 is cycled to read one card, a wire identification lamp 12, a pair of comb lamps 6 and a lamp in each bank 8 and 9 are lit. These, respectively, indicate the wire length, the comb locations, and the wire positions on each comb pair. A "From" comb can be identified by a lamp 7 steadily illuminated, and the "To" comb can be indicated by a flashing lamp. Lamp banks 8 and 9 are also identified as either "From" or "To". The o...
