Abstract

337,839. Evans, W. Dec. 24, 1929. Lantern screens.-An antidazzle device for a vehicle or other lamp comprises a skeleton cage formed by a number of springy metal stave-like fingers 1 shaped to be sprung over and to grip on to an electric lamp bulb, the fingers extending from the base of the bulb and meeting one another at the apex of the bulb. This device may be used in association with a reflector.
