(1) Note. This and the two succeeding subclasses, while not limited thereto, will include the so-called winnowing machines commonly employed for sorting threshed grain and flour sifters having the special structures or special elements of structure defined. Where the special feature or essential lies in the particular shake or means for producing the shake, the device is classified in one of the hereinafter listed subclasses taking devices having the shake specified.
