Abstract
Abstract A conveyor for simultaneously rotating and advancing cylindrical articles, such as lengths of pipe along a predetermined path of movement. Rollers having substantially spherical surfaces are mounted in two spaced parallel rows with the planes of rotation of the rollers in each row being parallel to each other. Roller drive is by a cylindrical member rotating on a fixed axis engaging the two rows of rollers from below, while the conveyed pipe lies in the trough formed by the two rows of rollers. The angle of the planes of rotation of the two rows can be simultaneously varied in opposite directions about an axis through the pipe by a pair of oppositely movable operating members extending the length of the conveyor and the mounting means are interconnected for simultaneous angle variation.

Claim 1
Independent Claim
213 words
In a conveyor for conveying elongated cylindrical articles along a predetermined path and including frame means supporting at least two laterally spaced parallel rows of a plurality of roller members having axes of rotation and pivot axes perpendicular to their axes of rotation and extending toward said path, said roller members being arranged so that their outer surfaces define an article receiving trough and for rotation of said roller members about their axes of rotation to rotate articles positioned in said trough about their longitudinal axes and to move the articles along said path, the improvement comprising: the outer surfaces of each said roller members havinG radii of curvature peripherally and longitudinally relative to said axes of rotation to provide said outer surfaces with a spherical configuration, and drive means including at least one elongated driven shaft means extending parallel to said path and frictionally engaging and driving at least some of said roller members in single point contact with said outer surfaces thereof, the portion of said shaft means engaged by said roller members being of uniform diameter whereby single point contact is maintained upon pivotal movement of said roller members about their pivot axes and said path is maintained at a given elevation relative to the axis of said shaft means.
