Abstract

27,639. Dawson, C. W. Dec. 19. [Patent of Addition to No. 7674, A.D. 1908.] Lamp shades and reflectors, and holders therefor. -An incandescent electric-lamp shade or reflector f is so held by a spring washer that it is prevented from being accidentally displaced. The washer j is preferably secured by a tail-piece j<1> to the shade f, and may be above or below the bentover portion g of the shade. The portion g is preferably smooth instead of corrugated, and may be formed with a circular hole with notches h to allow it to be dropped over the plug-piece b past the pins e, or it may be forked as shown in Fig. 3. The washer j is also forked, the semicircular part x of the fork opening being of slightly greater radius than the part g, or of slightly less radius if the washer is above the part g, so that it fits the wider or narrower part of the plug b. The spring washer may be a flat spiral, Fig. 6, which is oval in plan to enable it to pass the pins e.
