Abstract

1,259,607. Falling flap display apparatus; seeking arrangements. LAMSON ENG. CO. Ltd. 22 July, 1969 [23 July, 1968], No. 35010/68. Headings G4H and G5C. To cause a desired display to be exhibited by a falling flap apparatus 10, a switch 1 is operated to apply a voltage through selected ones of a row of microswitches 5 to close a relay 13, 12 to cause drive motor 11 to rotate the display 10. Motor 11 will continue to rotate so long as at least one of the chosen microswitches is closed. As the desired display comes into view, code areas 8 on a rotating drum 7 open all of the chosen microswitches 5, therefore allowing relay 13, 12 to open and motor 11 to stop. As described, drum 7 and display 10 have a common drive shaft 9, and the areas 8 are depressions in the drum surface. There are eight lines 3 and switch 1 selects three of them. The apparatus is useful as a railway train-indicator.
