Abstract

255,972. Stoddart, J. May 7, 1925. Motor-vehicle and like head lamps.-In a head lamp, a horizontal electric filament 5 is arranged transversely to and symmetrically with the focal axis of a Mangin mirror 1 and at about its focus so that a narrow intense beam of oblong crosssection is produced surrounded. by a weak light. A spider-holder for supporting the mirror is carried by a hollow sleeve 12 engaging a milled nut 11 at the back of the lamp, the limbs 6 of the spider-holder bearing against the hemispherical surface 9 of the lamp casing. The socket 8 of the lamp bulb is secured, preferably adjustably, to an extension of one of the limbs 6.
