CHARLES It. COE, OF BLOOMINGTON, ILLINOIS.

' IMPROVEMENT IN GRAIN-DRIERS.

Specification forming part of Letters Patent No. 133,410, dated November 26, 1872.

To all whom it may concern:

Be it known that I, CHARLES R. COE, of Bloomington, in the county of McLean and in the State of Illinois, have invented certain new and useful Improvements in Grain-Dri ers 5 and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon makin g a part of this specilication.

vThe nature of my invention consists in the construction and arrangement of a grain-drier, designed to be used for warehouses and for grain-bins and granaries on farms, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its constructionv and operation, refer- `ring to the annexed drawing, in which- Figure 1 is a horizontal section, and Fig. 2 is a vertical section, of my grain-drier.

A represents the warehouse or outside of the grain-bin. Withinthis exterior house or bin is a frame, composedof slats BB framed into the four corner-posts C C, which slats are Hat and situated at an angle of about forty to forty-five degrees from the perpendicular, and incline downward and inward. '.Ihis frame B C constitutes the grain-bin proper, into which the grain is thrown. In the center of forated metal may be bent and adjusted to a the same angle as the slats and properly'supported, as shown at H. rEhe bin B O is provided on the top with a wood cover, I, which operates as an air-deflector in the following manner: On the outside house or bin A is through the opening in its bottom. This deflector I may be used at the bottom ofthe bin' and the air forced upward, if so desired.f lIt may also be of any desired shape-flat, conil ical, or angular. In the house or outside bin AI intend also to arrange blinds K, as shown in Fig. 2, which are to be opened to allow the air to circulate where power is /not used to force the air down or up.

Having thus fully described my invention, what I claim. as new, and desire to secure by Letters Patent, is

1. In combination with theinterior grainbin B C, the central shaft or air-duct composed of the posts E E and inclined slats D D, or perforated metal plates, substantially as hereinset forth. i

2. The air-deiiector I, arranged either at the I top or bottom of the grain-bin B C, substantially as and for the purposes herein set forth.

3. The combination of the exterior shell A, interior bin B C, central shaft or air-duct D E,

deilector I, cover J, passages a b, and blinds K, all constructed and arranged substantially as and for the purposes herein set forth. y

In testimony that I claim the foregoing I have hereunto set my hand this 6th day of June, 1872.

CHARLES R. COE. Witnessesz W. M. HATCH, J. E. PUGE.
