ABSTRACT:
This device consists primarily of an upright backing member, called a backrest, having a perpendicular lip extending out from its base in a forward direction, and located at the inside bend of said perpendicular lip and backrest, is a spacer upon which an open book's weight is supported at its lower edges while its covers lean against said backrest. Along the lower margins and covering the entire width of the book's open pages, is held a flat rectangular plate of transparent material, which is simultaneously exerting a pressing force in a rearward direction against the open pages, this force is generated by means of elastic cords located at both the right and left ends of the flat plate, said cords are threaded through holes in the flat plate and bypass the book's page edges, then passing through similar holes in the backrest, they are terminated and held securely in the rear of backrest by means of knots in the cord ends, the knotting effect being enhanced by means of flat washers surrounding the finished knots. The backrest and its associated parts as an assembly is supported on a flat table or surface in a rearwardly inclined vertical position by means of a rear supporting plate projecting horizontally rearward in a direction perpendicular to the backrest, and is attached to the backside of the backrest by means of two bolts and wing nuts.
