Abstract

1310537 Recording apparatus FABRIQUES DES MONTRES ZENITHS A 24 April 1970 [9 May 1969] 19818/70 Heading G1J A recording tachometer for a vehicle comprises a pendulous mass 17 with freedom to oscillate, means 21, 22, 23 for recording periods of oscillation and non-oscillation of the mass 17, a spring 15 continuously biasing the mass 17 towards an equilibrium position and connected to a lever 13, and driving means 7, 10, 11 for oscillating the lever 13 upon movement of the vehicle. The spring 15 is connected to the lever 13 and to an arm 16 of the mass 17 at a point between its centre of gravity and a pivot 20. The lever 13 is also connected to one end of a rod 11, the other end of which embraces an eccentric 10 on a shaft 7 which is driven when the vehicle moves and also drives a distance meter. Oscillation of the mass 17 is limited by an aperture 19 therein engaging a fixed pin 18. In order to be able to regulate the pivot of the lever 13 in relation to the inclination of the tachometer, the lever 13 is pivoted on an eccentric 26 or a shaft 27 which is rotated to move the mass 17 until a mark 29 coincides with a fixed mark with the eccentric 10 in a given position indicated by a disc on the shaft 7 having marks to co-operate with a fixed pointer.
