Abstract: 759,651. Control of several motors. WESTERN ELECTRIC CO., Inc. July 23, 1954 [July 24, 1953], No. 21564/54. Class 38(3) [Also in Group XXII] Apparatus for interconnecting selected terminals of an array of electrical terminals comprises a wiring tool adapted to connect a wire to individual terminals of the array in succession and positioning means for moving the wiring tool to the appropriate positions for connecting wire to the selected terminals, the wiring tool and positioning means being controlled to effect the desired connections automatically in accordance with a predetermined wiring scheme. A wiring tool 16 which strips, winds and cuts a length of insulated connecting wire,' is mounted for horizontal movement along a carriage 17 itself mounted for vertical movement on splined shafts 21, 22. The tool 16 is moved horizontally along the carriage 17 by an endless belt 23 running over pulleys 25, 26 on the splined shafts 21, 22, the shaft 21 being rotated by an electric motor HOR. The carriage 17 is moved vertically by screw shafts 18, 19 driven by a motor VERT. A panel 41 having terminals thereon to be wired is supported by a frame 12 movable to and from the wiring means by a screw 43 driven bv a motor POS. The motors HOR and VERT each have a high speed field used to move the tool 16 at high speed to a commanded position, and a low speed field, used to adjust the position of the tool exactly when the tool overshoots its commanded position. The apparatus is controlled according to coded commands in the form of perforations in a strip fed a line at a time, under sensing or reader means. Each line comprises. Fig. 13, four groups of five positions which may be in a single row or staggered as shown. Two holes are punched in each group of five positions the combination of the two representing, for the end group U one of the digits 0-9 in units, for the group T. one of the digits 0-9 in tens, for the group H, one of the digits 0-9 in hundreds. and for the other end group C, one of the commands "Up", "Down", "Right", "Left". "Panel in", "Panel out", "Gun (or tool) wrap, initial end of the wire" and "Gun wrap, final end of the wire". The sensing or reader means include a series of fingers, those fingers encountering a punched hole in the strip closing contacts so that the corresponding two relays in each of four groups of five translating relays are energized to close a circuit in one of ten lines, for the relays of groups U, T. H and in one of eight lines, for the command relays of group C. For the command "Right 632," for example, the combination of relays in the C group closes a line to cause the motor HOR to move the tool at high speed to the right, to a position 632 units horizontally from a zero position. At this position, lines from the relays of groups U, T, H, which have been switched by the command "Right" to connect to the relevant segments 6, 3, 2 of a three section ten segment commutator 80, driven by the motor HOR through the spline shaft 21, allow current to pass through the commutator to first stop the high-speed movement and then start the low speed movement in the reverse direction until the overshooting has been corrected and the gun is correctly positioned. The next coded command e.g. "Down 069" is carried out when the perforated strip advances one step, current through a three-section ten segment commutator 81 driven by the motor VERT through the screw 19 stopping the motor VERT when the correct position 069 has been reached. At the next command e.g. "Panel in position 088" the panel 41 is moved forward by the motor POS until a single-section ten-segment commutator 82 driven by the motor POS switches the motor off when the panel has moved in to the correct one of ten positions. At the next command, e.g. "Gun wrap, initial end" the C group relays cause the wiring tool or gun 16 to strip the end of insulated wire fed to it and wrap it round the terminal on the panel 41 presented to the tool 16. The panel is then moved back and the tool 16 moved alonghorizontal and then vertical paths to the second terminal which is presented thereto and wrapped with the other end of the insulated wire. The insulated connecting wire is thus laid from a terminal A, Fig. 17, along a horizontal path, around a guide peg C in the panel 41 and along a vertical path to a terminal B.
