Abstract
A high speed gravity feed can conveyor comprises two facing C-shaped guides formed of hard chrome plated sheet metal. The guides are held in opposed spaced relationship by open U-shaped collars distributed along the conveyor. The collars distributed along the conveyor. The collars are formed with openings positioned downward having sufficient width to pass a can turned from a rolling orientation in the conveyor. The edges of the C-shaped guides are turned in a direction to support a rolling can and are covered with ultra-high molecular weight plastic to minimize rolling friction and protect the metal surface. The facing guide surfaces with chrome plating reduce sliding friction when a can end contacts a guide and reduce the potential for nicking the surface.

Contained trackwork for a high speed gravity feed rolling can conveyor comprising:
- a first elongate "C" shaped guide having a first inside surface, a first outside surface and upper and lower first angled edges, the upper and lower edges being parallel to one another and extending inwardly of the conveyor;
- a second elongate "C" shaped guide having a second inside surface, a second outside surface and upper and lower second angled edges, the upper and lower second edges being parallel to one another and extending inwardly of the conveyor, said second guide being in parallel spaced apart relation to the first guide, the first and second inside surfaces facing one another, said guides forming at least a lower slot between the first and second lower guide edges, said guides being adapted to contain rolling cans transversely aligned with said guides, with the first and second lower guide edges adapted to support a rolling can edge;
- and
- open collar means for securing said first and second guides in spaced apart relation and for permitting misaligned cans to freely drop between the first and second lower guide edges, said open collar means comprising a plurality of support collars positioned along said first and second guides, each collar comprising first and second connected sidewalls, each of said collars being "C" shaped and having an open end positioned below the first and second lower guide edges to permit misaligned cans to freely drop out of said trackwork, said first guide being secured along its first outside surface to the first collar sidewall;
- and
- means for adjustably securing said second guide along its second outside surface to the second collar sidewall.

A can conveyor section comprising:
- a sheet metal guide having a substantially planar elongate section of width slightly greater than a diameter of a can to be conveyed, opposed edges across the width of the guide being formed inwardly of the conveyor section and substantially perpendicular of the elongate section, at least one of the edges forming a rolling can support when the elongate section is vertically oriented;
- means for supporting an end of the can opposite an end supported by said sheet metal guide;
- a support collar for adjustably securing the guide within the conveyor section, the collar having a segment extending in a plane substantially parallel to a plane of the elongate section across the width thereof and a first bracket extending from the collar outwardly of the conveyor section;
- a second bracket attached to a surface of the sheet metal guide outward of the conveyor section, the second bracket being adjacent and extending parallel to the first bracket, each of the first and second bracket having at least one aperture extending therethrough;
- and
- a locking pin for securing the guide to the collar when the pin is inserted through the aperture in each of the first and second bracket.
