Abstract
620,465. Miniature diagram panels. STANDARD TELEPHONES & CABLES, Ltd., GRUNWALD, H. H., and COOPER, W. A. R. Jan. 20, 1947, No. 1784. [Class 105] [Also in Group XXXVII] A combined switch and indicating unit (see Group XXXVII) is used in a mimic diagram to permit the operation of railway points and to indicate their position. The switch, Fig. 1, comprises a tubular operating member 5 which may be rotated with the cylindrical shank 2 of a frame 1 by means of a knob 11, and has a cam-like portion 13 to operate one or more spring contact sets 14. Two lamps 19, are fixed to the frame 1, each lamp being arranged to shine on the end of a plate of transparent material 21, 22, Fig. 3. The plates are arranged in V formation and extend within the member 5 so that their upper ends closely underlie a translucent screen 18 in the knob 11. The operation of a points mechanism is controlled by the switch, the knob 11 being turned so that the arrow 30, Fig. 4, points in the required direction. When the points have been actuated, a circuit is completed to light the appropriate lamp, so that the light transmitted to the upper end of the corresponding plate shows the position of the points in relation to the routes 29 painted on the panel. The lamps 19, may alternatively be controlled directly by the switch as stated in the Provisional Specification. In a modification (Figs. 5 to 7, not shown) the switch and indicating unit has a single column of light transmitting material, which is used in conjunction with a number of coloured lamps. The switch -may then be used for the remote control of coloured light signals and the signal aspect is then shown by the appropriate colour appearing at the top of the column.
