Abstract: A buffing wheel hub device comprising telescoping male and female units having axially extending finger members supporting a plurality of buffing wheels thereon between end plates of said units to compactly support and drive said wheels rotatably by an arbor on which said units and buffing wheels are secured and mounted for rotation. The finger members each have arbor bore adjacent portions defined by radially inclined surfaces tapering toward each other and radially extending stems of substantially lesser transverse cross-sectional thickness than the transverse cross-sectional thickness of the bore adjacent portions, whereby flexing of the finger members under centrifugal force is generated, permitting improved engagement with the buffing wheels supported thereon. The end plates have openings transversely therethrough for passage of ambient cooling air into said hub and about said finger members. The finger members of one said unit are relatively shorter than the finger members of the other said unit.

Abstract: A material handling rack to translate articles having in part a V-shaped cross-section, at which the article is at least partially supported, and spaced apart relatively opposing generally upwardly-facing plastic article-support members removably secured to transverse rails affixed to the rack frame. The transverse rails are arranged in parrallel from one longitudinal end to the other and define open spaces therebetween for admission of said articles to be supported by the said plastic members which are secured to and extend laterally from the transverse rails into the region of the open spaces therebetween. Manually operable plastic detent hold-down arms are movably attached to the plastic support members to alternately engage with or disengage from laterally extending surfaces of the articles whereby to secure the latter in or release them for removal from the rack frame.
