Abstract: A wooden suspending ceiling system is disclosed comprising a plurality of parallel wooden runners extending in one direction, and a plurality of parallel wooden cross members supported by the runners and extending in a second direction perpendicular to the runners defining a generally rectangular grid system having a plurality of openings therein. Ceiling panels, lighting fixtures, or air vents are supported by the runners and cross members defining the rectangualr grid system and closing the openings therein. The runners and the cross members have an upper face and a bottom face, with the bottom face being viewable from below. The upper face of both the runner and cross members comprises a central portion with a groove on each side of the central portion, and with a lip outboard of each of the grooves. The inner surface of the lip defines the outer surface of the groove on each side of the central portion, and with a lip outboard of each of the grooves.

Abstract: A raised panel paneling system is disclosed comprising a plurality of paneling sheets securable to a substrate, with the edges between adjacent sheets varying between edge-to-edge abutting relation to a substantial maximum permissible gap therebetween so as to permit the sheets of prescribed widths to cover the substrates of varying widths within a limited range. A horizontal rail, such as a chair rail, is applied to the sheets at a predetermined distance so as to divide the sheet into a first portion and a second portion. A stile is applied to the adjacent edges of the sheets so as to cover the joint or the gap between adjacent sheets. A horizontal rail, such as a base board, is applied to one portion of the sheets, and another rail, such as a crown molding rail, is applied to the other end of the panel sheets.
