- 8 - FEEDER IDLER DRUM SHAFT WITH REMOVABLE EXTENSIONS ABSTRACT OF THE DISCLOSURE The idler drum shaft (59) of a feeder conveyor (28, 29) has a pair of detachable extensions (68, 69, 168) which when removed permit a floating idler roller (47) and the central portion (63) of the shaft (59) to be removed in a direction parallel to the conveyor side walls (41, 42, 116). The idler roller support arms (66, 67) of inside mounted tensioning mechanisms (56, 57) are connected with the shaft extensions (68, 69, 168) and also serve as abutments cooperating with upper and lower stops (81, 82) limiting vertical swinging movement of the floating idler roller (47). Washers (114) may be used to lengthen the idler drum shaft and to maintain a predeter- mined minimum lateral spacing between the idler drum support arms (66, 67).
