Abstract: A support for a grain bin having an elongated body with a back surface bent to form support surfaces that extend outwardly from the back surface to form a cavity therein. Connected to the elongated body is a base having a vertical portion and a horizontal portion. The horizontal portion having corners that extend upwardly to form flanges that engage the support surfaces of the elongated body.

Abstract: A pin member having a first section having a first rounded end and a second end and having a second section extending outwardly from the second end of the first section and having a diameter less than the diameter of the first section to form a shoulder. Extending from the shoulder is a third section having a diameter that is less than the diameter of the second section and that is an elongated cylindrical section that may be threaded. This pin member is inserted through a grain bin door jamb and cover to secure the door jamb and cover.

Abstract: A rotary grain screener is disclosed in which the primary grain-advancing flighting is mounted on the internal surface of the rotary screener drum and an inner auger is mounted on a central axial drive shaft to advance the grain forward in the drum at a greater rate than is accomplished by the flighting on the internal surface of the drum. The screener drum is supported on the central drive shaft which has a support bearing on the input auger housing and the drum is further provided at the input end with two annular bearing plates which are attached to the end plate of the drum and have a close fit around the input auger housing for closure and support purposes. A single motive power source drives the drive assembly which operates both the input auger and the screener drum.
