Abstract

1,039,893. Blasting. PANGBORN CORPORATION. Nov. 29, 1963 [Nov. 29, 1962] No. 47288/63. Heading B3D. A set of wear liner segments for completely covering the internal surface of a housing for a particle-throwing wheel includes front liner segments, rear liner segments, end liner segments, a top liner segment and elongated strip segments, the strip segments joining the end segments with the front and rear segments and extending up to the junctures with the top segments, the strip segments covering all joints at the junctures and the segments overlapping each other so that no joint between segments provides a pathway that leads directly to the housing. The rear wall 82, Fig. 1 (not shown), of the housing has a liner 119, Fig. 2, comprising segments 131-135 with their edges overlapping each other; the segments are secured to, but spaced from, the rear wall. Strip segments 151-154 rest directly against the internal face of the rear wall and have edges that overlap the edges of the segments 131-135. The front wall 81, Fig. 1 (not shown), of the housing similarly has a liner 120, Fig. 3 (not shown), comprising segments 161-165 and strip segments 171-174. End walls 84, 84, Fig. 2, of the housing have liners 121, 122 each comprising segments 181, 182 of channel shape with side lips that form an overlap with the strip segments. The segments 181, 182 are secured to, but spaced from, the end walls. The hinged lid 195, Fig. 2, of the housing has a liner 123 secured to, but spaced from, the lid with its edges overlapping the front, rear and end liners.
