ABSTRACT:
A drive chain is trained about drive and driven sprockets and is kept in proper tension by a tensioning device comprising a tensioning member located between the sprockets and extending transversely to the line of centers passing through the axes of rotation of the sprockets, the tensioning member including first and second spaced abutment surfaces facing toward the line of centers and engaging the opposite runs of the drive chain. A part of the tensioning member extends between the first and second abutment surfaces and is provided with an elongated aperture which is received on a pin located on the line of centers of the sprockets whereby as one of the chain runs tightens during operation it will move the tensioning member so as to effect tensioning of the other run.
