Abstract
466,568. Counting speed and other variations. KIENZLE, H. Nov. 28, 1935, No. 33019. Convention date, Nov. 28, 1934. [Classes 106 (i) and 106 (iii)] A device for counting in units all variations up or down in the speed of a motor-vehicle during a journey is used to check the operations of drivers following a regular route. The vehicle axle drives a centrifugal governor 1 which moves a cylindrical toothed rack 2 engaging a toothed wheel 3 carrying a spring - pressed pawl 4 driving a counting mechanism 8 through a ratchet 6. By using a second ratchet gear and counting mechanism, retardations may be counted as well as accelerations. A known device is used for resetting the device to zero. The Specification as open to inspection under Sect. 91 comprises also a device stated to be used for counting variations from a predetermined mains voltage. Coils 11, Fig. 2 (Cancelled), connected to the voltage excite poles 10, the rotary armature 9 carrying a pawl 4 for driving the counting mechanism. This subject-matter does not appear in the Specification as accepted.
