Abstract

755,358. Teaching electricity. SPIRLET, F. May 7, 1954 [May 8, 1953], No. 13371/54. Class 146(2) An apparatus for demonstrating electrical circuits comprises a plate 1, Fig. 1, of insulating material in perforations 2 in which may be inserted fixing members such as plain pins or projections formed on an apparatus 8, Fig. 5, such as a coil, The various circuits are distinguished by diversally coloured sheaths 6. Fig. 4 on coiled wire springs 5 with eyes 4 at the ends.
