The Anemocinemograph, which is made by J. Richard-Paris, is a very convenient instrument to record the wind velocity, but its anemometer is too delicate to stand against storm Therefore, the author has designed a new transmitting part of it. This transmitting part is attached to a Robinson's cup-anemometer. By means of a worm and a worm-gear, the rotation of the anemometer is conveyed to an axis, which mades one revolution per 100 meters of wind range. On this axis two cams are fixed; one is made in a shape of a round-cornered square, and another is elliptic. Two rollers, each of which is pressed to the corresponding cam, made to and fro motions, by which two electric circuits are closed and opened, one every 25 meters and another 50 meters of wind range. When the circuit for 25 meters is used, the recording part records the wind velocity, as usual, up to 30m/s, but in the case of the circuit for 50 meters, the wind velocity up to 60m/s can be recorded.
