To an odometer which has two parallel shafts, one being fitted with a plurality of distance-indicating wheels, while the other is fitted with a plurality of carry pinions which actuate said distance-indicating wheels, is fitted an alarm device, which comprises a means for triggering, which rotates together with one of said carry pinions, and an alarm switch, which is actuated by said means for triggering when it reaches a certain predetermined position during its movement together with its carrying pinion.

Alarm device for an odometer

An eddy-current meter comprises a permanent magnet fixed for rotation with a shaft whose rotation speed is to be measured. A metal cup is disposed close to the permanent magnet and attached to a spindle carrying a pointer. The spindle is rotatable against the bias of a spiral spring. The spindle is rotatably mounted on a support bearing of the shaft. A helical compression spring is mounted insuring that the support bearing of the shaft and the journal of the spindle are axially and yieldably biased toward each other with a force the magnitude of which is adjustable. The spindle is maintained in coaxial relationship with the shaft by two axially spaced radial bearings.
