ABSTRACT:
A control device for an instrument (10) attached to a vehicle wheel hub for recording the distance covered by the vehicle comprises a counting mechanism with several number-carrying wheels (25), a stamping mechanism (29,30) for stamping cards, a means (14) for advancing the number-carrying wheels of the counting mechanism in response to the distance covered, and a pendulum, the oscillation axis of which coincides with the vehicle wheel axle, and which by substantially standing still effects a relative movement in relation to the recording instrument. This movement is utilized for driving the means for advancing the number-carrying wheels of the counting mechanism via a gear unit (12). The means for advancing the number-carrying wheels of the counting mechanism comprise a feed hook (14), which is deformed permanently when number-carrying wheels of the counting mechanism are blocked, and thereby effects permanent closing of a first electric contact (14b-34). A movable member (18) in the gear unit (12) is provided with at least one signal shoulder (49), which is capable upon movement transfer of the gear unit to alternatingly open and close a second electric contact (33-34). Furthermore, an element (34,35) of the electric contacts is provided for scanning the condition of the electric contacts in order to render possible rapid observation, whether the recording instrument operates in the way intended.
