摘要

Counter of kilometers of travel, of adjacent drums, particularly suitable for its connection with the tachymeter of motor vehicles, of the type comprising a series of adjacent drums numbered from 0 to 9 and intended to indicate: the first, starting from the right, the kilometric units, the second the tens of kilometers, the third the hundreds of kilometers and so on, according to the number of drums that the meter is provided, advancing each drum, after the first, one step during the rotation of a tenth of a turn of the previous drum that sends it, communicating the rotation to the first drum a transmission sent by a tree that rotates proportionally to the turns of the wheels of the motor vehicle and that, in the case of the union of the counter with the tachymeter, is the same transmission that the latter commands, said counter being characterized by the fact that the pinion, with six teeth on the left side oy three teeth on the right side, which serves to transmit the control of a drum from the right to the adjacent drum on the left, is mounted on a bolt fixed cantilevered to a membrane of a disc arranged between the two drums, which is bent towards outside so that the part of the pinion with six teeth can mesh with an internal crown of teeth of the drum on the left and the other part with three teeth forming between them an angle of 120 degrees adhere with two teeth to the peripheral inner surface of the drum on the right, so that it does not allow the rotation of the pinion until it comes to correspond with a tooth notch provided on said surface.
