Abstract

204,288. Andersen, A. May 25, 1923. Magnifying-appliances. - A bar-shaped magnifying lens a is supported in mounts b hinged to a slide k, and is utilized for reading entire lines of reading matter on a printed page. The mounts are connected by bars c and hinged to pivoted supports e, the inclination of the lens being adjusted by a screw i. The aligning slide k is pinned to the lower supports e so that the height of the lens a above the printed page may be varied. The lens a, in a modification, is mounted on a rigid slide at a fixed inclination.
