Abstract
743,837. Conduits. ALLDAY & SON (1922) Ltd., H. Nov. 3, 1954 [Nov. 30, 1953], No. 33146/53. Class 36. [Also in Group XXII] A socket for use with a metal wall box containing a switch or other electrical device is made from a sheet metal blank a which has at one edge a pair of lugs c, and at its ends lugs d, e which overlap when the blank is folded longitudinally and then bent to circular form (Fig. 6) and which are united as by welding. The blank is first slit along lines b and then folded so that edge f lies along the line of the slits. It is then bent to cylindrical form so that lug d overlaps lug e, the parts c being bent outwardly to form lugs g. The inner surface of the cylinder may be screw-threaded for the reception of the externally-threaded end of a conduit. A side i of the wall box is provided with a semi-circular slot corresponding to the internal diameter of the socket, and with slots k in which lugs g are inserted. Part of the base h of the box is displaced to form a stop n and a gap m to receive the lower portion of the socket. When the socket is in position the lugs g are secured to the base h as by welding.
