Abstract

468,119. Speed-recording instruments. HASLER AKT.-GES. WERKE FUR TELEPHONIE UND PRAZISIONS-MECHANIK, and OCHSENBEIN, W. Nov. 16, 1936, No. 31327. [Classes 106 (iii) and 106 (iv)] In a speedometer having a pointer 7, a record of the speed and of the duration of the actuation of the brakes of a vehicle is produced on the pigment surface of a rotating disc 9, and a spring-pressed absorbent felt roller 22 saturated with a light-coloured liquid pigment periodically effaces the record line by applying a fresh coating of pigment. A pinion 6 on the pointer sleeve 5 moves a neck 8 carrying a spring- supported stylus 12 bearing on the underside of the translucent disc 9, which is rotated on roller bearings 13 by a pinion 17 driven through gearing from a shaft 4 driven by the vehicle. Under the disc 9 is a fixed disc 21 having a blackened upper face. The distance traversed while the brakes are applied is recorded as shown at 33 on the disc 9 by a stylus 31 which is moved inwardly by an electromagnet 32 when the brakes are applied and the rear stop light is illuminated.
