Abstract
A combined wind direction indicator and rain gauge is described in which the rain gauge is mounted on a vertically suspended sail at one end of a horizontally disposed elongated member which rotates in a horizontal circle in response to the force of inpinging wind. The rain gauge is so disposed that it is always maintained with its open mouth pointed into the direction of wind and at an angle of such that it coincides with the inclination of disending rainfall. Accuracy in measuring rainfall over a given period of time is thereby enhanced since the amount of rainfall collected will not be influenced by the angle of decent thereof. The device is further characterized by having a weighted head at the end of the elongated member remote from the rain gauge to counter balance the weight of the rain gauge and the sail on which it is mounted.
