Abstract

156,024. Brown, R. March 3, 1920. Vehicle lamps.- In a vehicle head lamp having a paraboloidal back reflector 2, the upper half of the lantern front is covered by a rearwardly-reflecting surface of paraboloidal form, both paraboloidal surfaces having a common focus and a common axis. The rearwardly-reflecting surface may be formed on a separate piece of metal attached to the front glass, or an integral projection 7 on the front glass may be mirrored to serve as a reflecting-surface 10.
