Model of a Fan, Model of a fan, acting as a double bellows. In the large rectangular compartment, a board, which is hinged at half height against the short front, is moved up and down with a lever, the two halves in which the compartment is divided by the shelf are in turn reduced and enlarged. Air is let in by two square valves on the front, consisting of simple valves covered with chamois leather, one above and one below the hinges of the shelf. Through similar valves, the air is discharged to a small front compartment where the air flow is directed to a single outlet in a square ventilation
