  • Bush securing mechanism
    Patent number: 4685172
    Abstract: A bush element for supporting a rod or shaft in a side plate has portion for entry into a generally circular aperture in the side plate. The portion of the bush has tooth shaped projections extending radially outwardly such that the overall diameter of the portion exceeds that of the aperture. The aperture is enlarged at a position to receive the projections so that rotation of the bush in the side plate results in the extremities of the teeth being cut away by the side plate to ensure a precise fit of the bush in the side plate.
