Total Claims: 5
Claim 1
Independent Claim
103 words
An apparatus for holding copy and following lines comprising a backing on which elongated side extensions are laterally mounted, said side extensions having walls toward the inside at right angles to the backing, the walls of the side extensions having facings of magnetically attractable material extending angulary outward at the bottom over said backing, a rod with magnetic end members sufficiently long and horizontally positioned so that its said end members adhere magnetically to said facings and to their angular extensions, said rod capable of being manually moved to follow lines on the copy and an adjustable easel on which the backing rests.
