Abstract

823,347. Changing signs. AYERS, F. P. and BOATFIELD, G. W. Feb. 17, 1958 [July 22, 1957], No. 23075/57. Class 3(1) In a changing sign of the relatively movable disc type for tradesmen and adapted to be mounted on a door the rotatable disc 6 is formed integral with a starshaped wheel 9 and the fixed outer disc 1 is provided with a pivoted detent 11, 12 for locking said wheel in position. The detent may be spring- loaded and is positioned adjacent the door jamb to prevent interference with the setting when the door is closed.
