Abstract
A top dresser (10) includes sheeting (70) in the form of an endless belt passing around first and second drums (148, 160) and a bed (166) including a plurality of rollers (106). Continuous V-shaped guides (122) are received in pulleys (120) on the drums (148, 160) for tracking the endless belt. A blocking device (112) in the form of a rod is slid in the mid-frame (102) to prevent the shafts (108) of the rollers (106) from axially sliding against their bias from their operative positions to their installation positions. Ledges (116) having friction reducing strips (118) extend over the shafts (108) of the rollers (106). A compound gear (180) in gearing relation with the second drum (160) and in driving relation with a spindle (82) of a brush (74) is rotatably mounted to an arm (174) pivotally mounted to the second drum (160). The spindle (82) includes two portions (82a, 82b) removably connected by a coupler (76), with the first portion (82a) being cantilevered supported from the side frame (100).

- a first drum;
a second drum parallel to and spaced from the first drum;
a bed extending between the first and second drums;
an endless belt passing around the first and second drums and over the bed, with the endless belt including an operative surface adapted to transport material and an engagement surface engaging with the first and second drums and the bed, with the bed comprising a plurality of rollers located intermediate and parallel to the first and second drums, with each of the rollers including a shaft defining an axis of rotation, with the shaft extending beyond axial ends of the roller, with the bed including first and second frames, with each shaft including first and second ends and being axially slideable within the roller and biased from an installation position towards an operative position, with the first end of the shaft being axially spaced from the roller greater in the installation position than in the operative position, with the first end of the shaft slideably received in an aperture formed in the first frame and the second end of the shaft slideably received in an aperture formed in the second frame; and
a blocking device removably secured to the first frame for abutting with the first end of the shaft received in the aperture of the first frame and in the operative position for preventing the shaft for sliding within the roller to the installation position. - View Dependent Claims (14, 15, 16, 17)
