Abstract
Abstract An adjustable support apparatus to hold books or other reading matter in position so as to enable lying or seated individuals to read. The apparatus consists of a transparent plate, preferably of acrylic plastic, which is supported by an adjustable arm attached either to the bed head board or to a portable stand. Shielded tubular light bulbs on each side of the transparent plate may be rotated so as to cast light from either below the plate, or to a position above the plate so that the reading matter may be illuminated for reading from below, or from above the support level.

A support apparatus for the purpose of holding books or other reading matter in a position to be illuminated so as to be read by a person without using his limbs to support the reading matter, consisting of a transparent support member affixed by a jointed support arm with attachment means for fastening to a vertical support member, such as a bed headboard or a portable stand, with a shielded light source fixed to a side of said transparent support member so as to illuminate material resting on the transparent support member in order that such reading material may be viewed from either above or below the transparent support member, as desired, in which the shielded light source may be rotated from below the transparent support member, to above the transparent support member, so as to illuminate material resting on the transparent support member from below, or from above the transparent support member, said light source being pivotably mounted in a shielded housing to one side of the transparent support member, with the axis of the pivot of the mounting of the light source being parallel to the fastened side of the transparent support member, together with stop means to fix the light source mounting in a given position with relation to the transparent support member.
