Abstract

158,935. Chinn, W. Oct. 13, 1919. Variable-speed gearing suitable for motor vehicles is provided with means for indicating the relative speeds of the teeth of different gears so as to facilitate changing speed. A " master " pointer h is driven through a governor c and flexible shaft i from the driven or tail shaft o<1> of the change-speed gear. Other pointers s, w, z geared together and turning about the same axis as the pointer h are driven through a governor c<1> and flexible-shaft h from the driving-shaft. The positions of the pointers s, w, z indicate respectively the speeds of the teeth of a clutch o, Fig. 3, and of countershaft gears p', p<2>. In Fig. 8 is shown the indication at the top speed. If this speed is disconnected, and the car slows down, the pointer h turns to the left, passing over the others. When the pointer h coincides with the pointer w as shown in Fig. 6, it means that the corresponding speed may be engaged without shock. If the engine varies in speed, the pointers s, w, z open out or close in so as to indicate on the inner scale shown the speeds of the corresponding gear. The position of the pointer h on the outer scale gives the speed of the car absolutely in miles per hour. Reference has been directed by the Comptroller to Specifications 8065/07, 22312/13, 5843/14, and 107,102.
