Abstract

429,651. Maps. BERRY, S. B., 44, The Grove, Isleworth, Middlesex. April 6, 1934, No. 10461. [Class 146 (ii)] A map, chart, or the like is provided at each of a number of stations or centres known to be equipped with wireless direction - finding apparatus, with representations of compass points and degrees, and each centre is also equipped with devices enabling indicating means to be pivotally moved therearound. The indicating means may be in the form of one or more pointers which are permanently or removably fixed to the map at the centres referred to. The indicators 5, 6 may carry one part of a pressstud fastening 3, companion parts 2 being fixed at each of the centres. The indicators may be provided with scales for determining distances, and may be slotted as at 7, to facilitate the ruling of lines on the map, the surface of which is formed of celluloid-covered fabric or other matt-surfaced material. The indicators may be of celluloid or other translucent material.
