805,364. Diagram boards. SWANGREN, E. G. F. Dec. 23, 1955 [Dec. 28, 1954], No. 37448/54 Class 146(2) [Also in Group XXXVIII] In an indicator board 1 for diagrams, graphs, &c. indicator symbols 4, 6, 7, 8 are held on the board by means of split pins 3 inserted in apertures 2 in the board, the closed ends of the pins acting as stops for the pins and holding the symbols adjacent the face of the board. The two limbs of a split pin may be passed through a hole in a symbol 6 to hold the latter against the board, or one limb only may be passed through the hole so that the symbol 7, 8 is suspended from the eye of the pin and turning the pin through 180 degrees reverses the symbol. Strip symbols 4 are provided with a series of holes 5 coincident with holes 2 and are mounted by pins inserted in desired holes. Strip symbols may comprise wires which are threaded through the eyes of pins 3.
