Abstract:
It will he observed that the pneumatic means for advancing the straw have independent and separated discharge-orifices arranged one in advance of the other and all arranged so that the blast, from each enters the straw passageway from below, and also with a movement in substantially the direction which is being taken by the straw as it advances toward the main delivery-duct, and from this arrangement it follows that the straw is successively both lifted and advanced by the air.
Claim:
The combination with a threshing-machine of the straw-delivery duct, the straw-receiving duct communicating therewith, the chaff-duct communicating therewith and situated below the straw-receiving duct, blast devices supplying air to all of said ducts, and means for dividing the blast to cause the same to act independently on the straw at different points. |
