MOUNTING FOR AGRICULTURAL TOOLBARS AND TUBES OF DIFFERING CROSS SECTION.

摘要

Tube mounted bracket structure for a toolbar or similar tube with a rectangular cross section includes a bracket having a tube abutting flange with an aperture offset from an elongated slot. A rotatable insert has an inwardly directed and elongated projection conforming to the shape of the elongated slot and aperture located at one extremity of the projection. The aperture extends through the projection and through an integral washer portion which defines an enlarged shoulder area for contacting the tube abutting flange when the insert is positioned in the slot. The elongated projection generally fills the entire slot with the exception of the aperture thereby presenting a relatively solid bolt receiving area for mounting a U-bolt or similar bolt structure. For a toolbar or tube having relatively large cross section, the insert is positioned in the slot to provide maximum offset from the flange aperture. If the bracket is attached to a toolbar or tube with smaller cross section, the insert is rotated 180 degrees from the position for the first cross section so the projection aperture is positioned to provide minimum offset from the flange aperture.
