Abstract
539,071. Doors. BUNTON, S., and CRAWFORD, W. Feb. 26, 1940, No. 3526. [Class 20 (iii)] Doors are constructed of two flat panels of synthetic resinous material spaced apart by edge pieces to which they are connected mechanically. The resinous material may be of the cresolformaldehyde type with a filler of finely shredded cotton rags or waste paper, or the material may be laminated. In the latter case, reinforcing material such as paper, cloth, wood veneer, or wood ply is impregnated with synthetic resin and the layers are subjected to heat and pressure to fuse them together. The panels may be bound together by strip-like members of synthetic resin which engage the opposed faces of the panels by sliding dovetail connections. Alternatively, the panels may be secured to opposite sides of a rectangular wooden frame. Along the edges of each panel P, Fig. 2, ribs P' of synthetic resin are attached by screws or cement, and edge strips 9 are slid into engagement. Intermediate binding strips 7 may also be used. Hinges may be secured to the edge strip, and at the lock position the strip may be slotted to receive them. The hollow space within the door may be filled with ash. In a modification, the panels are secured to-both sides of a wooden frame, the edges of which are then covered by strips of synthetic resin.
