Model finishing fanners, or duster
This is a model of an improved early 19th century winnower which is used for separating grain, chaff and weed seeds by means of the blast from a fan and reciprocating screens which sieve the grain but shake forward into a chute such large weed seeds as thistle heads, etc. Small weed seeds are separated at a stationary slanting sieve which holds the larger grain seeds.
