Description: |
| Abstract:
The object of my invention is to provide an improved means for the removal from the machine of the fine particles of dirt and small seeds that escape through the usual screen in the lower grain-pan of a threshing-machine, such that such fine particles of dirt and small seeds shall he carried to one end of the machine and delivered there in a pile rather than having such fine particles of dirt and small seeds delivered to a barrel by the usual worm working in a trough. I have found that the use of a barrel for catching this refuse is objectionable, in that it takes up room and the barrels when full have to be removed and replaced by empty ones.
Claim:
In a threshing-machine, in combination with a grain-pan having a screen therein and a trough and worm beneath such screen, a fan supported at one end of such trough and worm therein, such worm arranged to deliver the contents of such trough to such fan, and means for revolving such fan and delivering the contents emptied therein from such worm to one end of the machine, such fan supported on a sleeve revoluble on the shaft for such worm, such sleeve also carrying a pulley by means of which such fan may be driven. |
