Abstract
115,400. Hough, E. R., and Harrison, L. Feb. 26, 1918. Addition to 2928/15. Guards and protectors; globe-holders. - In the electric lamp fitting described in the parent Specification in which a ring c carrying the lamp guard engages internal spiral slots in a cap or dome a and is provided with a locking-screw g for securing it in position, the cap or shield h surrounding the locking-screw so as to prevents its improper operation is provided with a lateral extension k having an aperture l for the head of the key to be introduced sideways, the shank of the key being then slid along a lateral slot o in the extension k until the head of the key is brought into position to pass into a second shield surrounding the head of the screw. The key may have a flat shank and the inner end p of the slot o is then sufficiently enlarged to enable the shank of the key to turn.
