Abstract

985, 661. Symbol displaying devices; educational appliances. H. R. SAVAGE. July 20, 1961 [July 20, 1960], No. 25346/60. Headings G5C and G5G. A device for use in selecting combinations of signals for crossword puzzles &c. comprises seven cylindrical members 13 supported on discs 15 which closely fit a shaft 11 journalled in bearings in a housing 6 with a windowed aperture 9. Each member 13 carries symbols 18 and rotates when the shaft 11 is turned except when grooves 19 in the periphery are engaged by a spring 21 which is moved into position by a lever 25 projecting through the housing. A spring ball catch 29 mounted on a boss 32 on the shaft 11 rotates with the shaft and co-operates with depressions 28 in each member 13. In alternative embodiments the supporting discs 15 may be replaced by radial arms carrying flanged wheels for co-operation with the members 13.
