Abstract

809,473. Electric battery lamps. MAGALOW, W: April 10, 1957 [July 18, 1956; Feb. 28, 1957], Nos. 22242/56 and 6751/57. Class 39(2) [Also in Group XV] An electric battery lamp has the casing constructed so it may be used as a mileage indicator. As shown in Fig. 3, an inner cylindrical part 10 has mileages marked on it and rotatably mounted over it is a cylinder 11 marked with a map or chart with place names and adjacent windows 5 through which the mileages may be read. The cylinders 10b, 11b, Fig. 5, are constructed of clear plastic and the lens 21 shaped so that the light may be reflected back into the cylinders 10b, 11b. Alternatively an end cap 28 may reflect the light. The relative movement between the cylinders may be obtained by an axial movement
