摘要： A meter for use in a multi-speed vehicle for indicating both the rotating speed of the engine and the running speed of the vehicle by a single pointer. The meter comprises a character drum of polygonal cross section, and speed scales corresponding to individual gear positions of the multi-speed vehicle are provided on the different side faces of this character drum. This character drum is suitably rotated to expose the desired one only of the speed scales in a display window formed in the dial of the meter so as to prevent the operator from reading other speed scales.
摘要翻译：一种用于多速车辆的仪表，用于通过单个指针指示发动机的转速和车辆的行驶速度。仪表包括多角形横截面的字符鼓，并且在该字符鼓的不同侧面上设置对应于多速车辆的各个档位的速度刻度。该字符滚筒被适当地旋转，以便在形成在仪表的表盘中的显示窗口中露出所需的速度标尺，以防止操作者读取其他速度。
