Abstract
331,455. Smith, R. A., Baggs, H. G., and Wilkins, J. A. Oct. 12, 1929. Hand lamps without lanterns.-In a portable electric hand lamp a curved shade or reflector K is held in position in an annular shouldered recess D in the body or handle portion A by means of one or more projections J on the hinged door L of a guard G. The reflector K comprises a cylindrical or conical sheet of metal, cardboard, celluloid or other material and extends around approximately half the circumference of the guard. The latter is preferably constructed of wire, the projections J being formed by turning up parts of the hinge H. The handle A is made in one piece of wood or other insulating material and is provided with a recess F for shielding a lamp-holder E, which is preferably made of insulating material, and with a gland B for gripping the flex C.
