Abstract

221,738. Kieffer, N. J., and Osa Apparate-Ges. March 10, 1924. Magnetic speed indicators.-In an eddy-current speed indicator in which the rotating magnet system comprising a magnet f and an irou cover plate g encloses the armature i, the worm q for actuating the wheel r of the mileage register is formed on the extension p, which also provides the upper bearing support for the armature spindle k.
