摘要： A tensioning system for a cleaning blade having a frame, a blade support, and a ratchet system. The blade support is movable around a first axis in a first direction to increase cleaning blade pressure and an opposite second direction. The ratchet system has (a) a first ratchet assembly with at least one ratchet surface facing in a first circumferential direction and (b) a second ratchet assembly having a first plurality of ratchet surfaces facing in a second circumferential direction. At least a part of one of the first and second ratchet assemblies is deformable to allow the blade support to pivot in the first direction to cause the one ratchet surface to (a) move past each of the ratchet surfaces of the blade support moves in the first direction and (b) abut one of the ratchet surfaces to block movement in the second direction.

摘要： A conveyor system having a conveying belt trained around a plurality of guide rollers for movement in an endless travel path to convey articles and materials in a travel line. A first roller is mounted in an operative position on a support to bear against the conveying belt. A roller safety support system has a wall assembly that confines downward movement of the first roller in the event that the first roller becomes disengaged from the operative position. The roller safety support system further includes a frame assembly. The wall assembly is mounted to the frame assembly so that an upwardly facing surface on the wall assembly bears supportingly against the first roller in the event that the first roller becomes disengaged from the operative position. The upwardly facing surface bounds a receptacle in which the first roller is confined by the wall assembly in the event that the first roller disengages from the operative position. The receptacle has a variable configuration.

摘要： An apparatus is provided for preloading a scraper blade against a conveyor belt in a conveyor cleaning system. The apparatus includes a blade support adapted to mount a scraper blade for engagement with a conveyor belt, a torsion member including a first end segment spaced from a second end segment along an axis, and a stop engageable with the second end segment to maintain the torsion member in a preloaded condition with the second end segment rotated about the axis relative to the first end segment to generate a preload between a scraper blade mounted on the blade support and a conveyor belt. In one form, the first end segment has an essentially polygonal cross section engageable with the blade support to restrict rotation of the first end segment relative to the blade support.
