Abstract: Driven and idle sprocket wheels are journaled in aligned relation for rotation about spaced apart parallel axes and a chain is trained over the sprocket wheels. The sprocket wheels are journaled from a support structure and the latter includes an elongated support member guidingly supported therefrom for rectilinear reciprocation along a path generally paralleling the reaches of the chain extending between the sprocket wheels.
