Two styles of shuttle stuffers.

Two styles of shuttle stuffers, one with a large wheel and one with a smaller wheel. They are made of mixed wood and metal. The shuttle stuffers have a base (one with either three or five legs, and one that is more like a column) on which a wheel is oriented vertically. Slightly to the side of the large wheel, on the base, is what appears to be a funnel or holster. The shuttle stuffer in the foreground has a second, much smaller wheel attached to the frame by way of a lever arm. It appears as though the smaller wheel may rest on the rim of the larger wheel. The shuttle stuffer in the background has large wooden rod in the funnel / holster.
