Abstract: An improved fan blade is characterized by a fan blade body and anchors extending therefrom. The fan blade body includes opposingly paired ends and opposingly paired sides, the opposingly paired ends for extension between a backplate and a wheel cone of a fan wheel assembly, with each side of the opposingly paired sides for united extension across a portion of each of the backplate and wheel cone of the fan wheel assembly. Each anchor of the anchors includes an aperture, with each anchor of the anchors substantially extendable through a portion of either of the backplate or wheel cone of the fan wheel assembly such that at least a portion of the aperture of the anchor extends beyond either of the backplate or wheel cone of the fan wheel assembly with the at least a portion of the aperture of the anchor for receipt of an anchor pin.

Abstract: A dragline comprising a main housing, and a moving mechanism for moving the main housing over the ground, the moving mechanism including a drive mechanism mounted on the main housing, an output shaft which extends along an axis and which is driven by the drive mechanism, the output shaft having inner and outer ends, the inner end of the output shaft being spline fit to the drive mechanism such that the drive mechanism causes rotation of the transmission output shaft, a pedestal fixed to the main housing, the pedestal including a leg which has therein a bore centered on the axis, an output pinion mounted on the output shaft intermediate the inner and outer ends thereof for common rotation therewith, and a bearing capsule housed in the bore, the bearing capsule rotatably supporting the outer end of the output shaft, the leg of the pedestal including base and cap portions respectively defining lower and upper halves of the bore, the cap portion being removably fixed to the base portion, such that removal of the

Abstract: The disclosure involves a structural combination and a method for attaching a machine component such as a number of arc-shaped gear segments to a supporting segment mounting pad. As new, each gear segment is furnished with a number of openings, all of the same diameter. Initially, the mounting pad is free of openings and each gear segment is placed on the pad and used as a drilling template. After openings are drilled in the mounting pad, a number of such openings (but not all) are "opened up" by reaming and a bearing-fit bolt is inserted into the reamed openings. In repair, a new gear segment is placed at a position which spans two places formerly occupied by gear segments. Certain openings in the new segment are aligned with existing openings in the mounting pad (to receive clearance-fit bolts therethrough) and other segments openings are used to form new openings in the mounting pad.
