The application of the date indicator to a pen or propelling pencil is shown in Figs. 5, 6, the discs a, b being rotatable on a pivot pin d and held in position by a washer l. The date indicator may be constructed as an ash or pin tray, paper-weight, inkstand &c., and made. of metal, glass, celluloid, or other substance.
