Title: Improvements in charts or indicators
IPC: G09F7/00
Filed: 1953-12-04
Abstract: 749,882. Indicators SANDERSON, G. P. April 27, 1954 [Dec. 4, 1953], No. 33803/53. Class 118(1) [Also in Group XXV] An indcator board comprises a plurality of units 2 stacked vertically in a housing 1, each unit comprising a plurality of coloured strips which may be moved to show selected amounts of differing colours through an aperture in the front of the unit. Adjustment of the coloured strips can only be effected when the units are removed from the housing which is however normally locked against such removal by the provision of a lock 34. Cursors 3 extending in front of the apertures in the units 2 may be adjusted, when the housing is unlocked by means of the knobs 46, 47. Fig. 3 is a horizontal section showing a unit 2 in place in the housing 1. When the housing is locked vertical rods 28 of semi-circular cross-section engage in slots 11 in the unit 2; in the unlocked condition of the housing however, the lever 33 may be moved to the left, thus rotating the rods 28 to the position shown, thereby permitting the units to be removed. Figs. 9 and 9a show portions of a unit with its cover plate removed. The unit comprises channels 6 each containing three strips of differently coloured material attached to respective manually-operable sliders 25, which are movable within a channel 17 extending through the cover plate as shown in Fig. 3. With the sliders 25 in the positions shown in Fig. 9 and 9a the strips are concealed from view; however, on moving the sliders shown in Fig. 9 to the right coloured strips appear behind the aperture in the unit from the right while on moving the sliders shown in Fig. 9a to the left coloured strips appear from the right. A transparent scale 18, Fig. 5, is arranged in front of the aperture. As shown in Fig. 11, the cursors 3 each comprise a cord having a plug 42 attached to one end for insertion into a socket 43. The cursor cords pass within tubular columns 37, 38 where they support weights 39 keeping the cords taut. Thus when it is desired to remove units from the housing the cursors may be moved out of the way by removal of the plugs 42 from the sockets 43. The cursors are moved by cords 48, 48a which are attached to their respective columns 37 38. The locking rods 28, having the semi circular section, are rotated by means of linkwork, Fig. 12 (not shown) coupled to an operating lever 33, the lock 34 carrying an extension 35 which allows the lever to be moved only when it is in the unlocked position as shown in Fig. 11. Rotation of the rods 28 to their free position also releases the lever 64 which may then be moved to the right thus opening the jaws 61, 62 normally gripping the cords 48, 48a so that the cursors may be moved.
