Abstract
104,759. Mitchell, J. B., Shaw, A. B., and Taylor, W. March 27, 1916. Shade, reflector, and like holders.-Shades, reflectors, or light-diffusers for electric or other lamps are supported on the inner side so that they can be readily disengaged from above or from underneath the shade &c., when it is desired to remove them for the purpose of being cleaned. As shown in Fig. 1 applied to a pendent electric incandescent lamp, two spring-controlled arms d pivoted to the lamp-holder a are provided with extensions. g bent to form outwardly projecting shoulders adapted to engage the inner side of the shade i, as shown, the arms being also provided at their supporting points with curved lateral wings h to afford additional support to the shade. The arms may be fixed to a sleeve adapted to be applied to an ordinary lamp-holder, the sleeve being slit vertically to enable it to be passed over the leads, and to accommodate the switch spindle when it is slid into position on the holder. In a modification, the arms are formed of wire coiled to form a spring connexion at the upper end, thus dispepsing with the pivotal connexion.
