143,715. Mann, Egerton, & Co., and Drummond, A. B. May 22, 1919. Displaying information.-A device for indicating the progress of work passing through workshops, offices, &c. comprises a disk 1 mounted on a stand 2 and having movable pointers of different lengths. The disk 1 has mounted on it a smaller disk 3 hav. ing radial nicks or grooves 4 in which the ends of the pointers engage, both disks 1, 3 being mounted on a spring-pressed spindle so as to be independently rotatable. The pointers are spring- pressed and arranged one above the other so as to be capable of passing one another in both directions. The outer part of the disk 1 is covered by a removable surface 8 bearing annular columns 10 carrying information which is diagnosed by one or more rotatable arms 11 similarly divided. The surface 8 is held on the disk 1 by a clamping-ring 7 formed in halves. Coloured identification disks 13 may be placed on the pointers, which approximately equal in number the columns 10. A graph chart may be fixed beneath the disk 1.
