Abstract
A load supporting conveyor having live rollers forming a load conveying path in which the rollers are driven by a chain having horizontally placed links and vertically positioned rollers with vertical axles that project upwardly toward the live rollers to be engaged by a flexible pad substantially aligned with the drive chain and an aperture pattern formed in the pad to establish a series of apertures that have a tight fit with certain ones of the vertical axle projections and a series of other apertures that have a loose fit with a like series of vertical axle projections.
Claims8
A roller conveyor for the transportation of a load having rollers having forming a path for the travel of a load, a drive chain extending along the load moving path of rollers, and friction means engaged on the drive chain in position to contact the rollers for effecting the travel of a load, characterized in that the engagement between the friction means and the drive chain comprises a series of spaced projections on the drive chain, and a series of apertures formed in the friction means to receive the projections in which certain of the series of apertures are tightly fitted over a like series of projections on the drive chain, and others of the apertures in the friction means are loosely fitted over others of the projections on the drive chain.
A roller conveyor for the transportation of a load having a path of travel of the load defined by load supporting rollers, a driver chain extending along beneath the load supporting rollers, and friction means supported on the driver chain in position to engage the load supporting rollers, characterized in that the driver chain presents a series of spaced and similarly sized projections directed toward the load supporting rollers, and the friction means is formed with a pattern of apertures fitted onto the series of spaced projections on the driver chain wherein the pattern of apertures include certain ones having a size to tightly fit over like ones of projections on the driver chain, and other apertures having a size to loosely fit over like others of projections on the driver chain, and the tightly fit ones serve to propel the friction means and the loosely fit ones serve to maintain the friction means in substantial alignment with the driver chain.
