Description: |
| Claim:
The nature of my improvements consist, first, in constructing the feeder that receives the grain with three or more successive steps, composed of slats of wood, with openings between each one, which peculiar construction assists in feeding, by the blast created by the fan, being forced through said openings and driving off the loose straw, &c., which tends to obstruct the passage of the grain.
