Abstract
An improved hoist for electric ceiling lamps, characterized in that its essential winding drum is of ribbed useful profile, split into two pieces by its central plane of symmetry, perpendicular to the axis of rotation; joining both pieces by rivets through said plane; because these two parts have molded the corresponding halves of a central tube into which is inserted the flexible conductor that connects the network with the lamp and that serves mechanically as a cord to suspend and adjust the height of the luminous focus thereof; one of these two pieces forms the anchor for the external end of the spiral of a spring that between the reel and its axis of rotation and the opposite part presents fixed in the internal edge of its lateral face a certain number of fixed axes eccentrically for others so many triggers that will act as ratchets with respect to a solidary wheel with an inner tubular shaft and concentric with that of the reel and involving the central and fixed axis of the assembly.
