774,198. Lighting fittings. THORPE, Ltd., F. W.. and THORPE, F. W. July 6, 1955 [July 8, 1954], No. 19966/54. Class 75(4) The fluorescent electric lighting installation described in Specification 700,987 is modified by omitting the hook edge on one side of the reflector support 4 and providing that side 7 with movable hooks 10 spaced longitudinally of the support and which are normally biased as by a spring 9 into engagement with the rail 3 and can be moved into a disengaging position by manually operable means such as the button 13 projecting through an elongated hole 14 in the side 7, to be accessible at the exterior of the side 7. Each hook is of strip material and is hinged as at 11, to the web 12 of the support 4 at a corner position.
