Abstract
Guide structure for assisting in the connection of a dipper stick of a machine, such as a back-hoe to a tool, such as a bucket, which is operated by the machine. The tool has a connection portion provided with a pair of aligned openings. The dipper stick has a tubular connection member which must be aligned with the openings in the connection portion for attachment of the tool to the dipper stick. In this invention a pair of guide flanges is attached to the connection portion of the tool. Each guide flange has an abutment portion which is positioned adjacent one of the openings in the connection portion. In the procedure of attachment of the dipper stick to the tool, the dipper stick is moved, and the tubular connection portion is guided along the guide flanges until the tubular connection member engages the abutment portions of the guide flanges. When the tubular connection member engages the abutment portions of the guide flanges, the tubular connection member is in alignment with the openings in the connection portion of the tool, and a fastener is inserted through the opening and through the tubular connection member, and the dipper stick is thus attached to the tool.
