Display system for measuring instruments - has pointer moving over plate with numbers and mounted on support extended to pass through hole in plate

摘要

The display system has a pointer and a measuring arrangement on each side of digit plate. The pointer is fixed to a support which is coupled via a spindle through a hole in the digit plate to the measuring arrangement. The pointer (1) is fixed to the support in the correct position and the support (2) is led through the hole (8) in the digit plate (5). The radial extent of the support is roughly the size of the hole. The pointer is fixed to the support by a ratchet or snap-action device. Several pointers with several measuring arrangements may occupy the same digit plate. The pointer may pivot on the support or may be secured by a cap. ADVANTAGE - Simple combination of a measuring arrangement with a digit plate.
