Pedometer

Pedometer, in its simplest form, is an instrument used for measuring the number of paces taken by a pedestrian. It is generally of the shape and size of a watch, and is carried in the pocket, a movable lever or pendulum moving at each pace taken and recording the same by means of a needle which traverses a certain marked space on the dial. Modifications of this instrument attached to a wheel will register the number of revolutions made, and a similar contrivance is used to register the revolutions of the screw or paddle-wheels of steam vessels.
