Abstract

187,801. Williams, E. B. Sept. 21, 1921. Junction boxes ; plug counlings. - In an electrical connection or lighting box comprising two parts a, b having conical ends adapted for clamping thereto armouring wires, the armour clamps e, f clamping the, two parts together also, connections axe made to the uncut conductors h of the cable by an independent insulating block r carrying two tubes s having clamps u projecting to its sides to which the main conductors are secured. The branch leads v, are soldered into ordinary plugs or plugs w which after insertion into the tubes s may be expanded therein by conical plugs z driven or screwed into them. The box may be used for a lamp and glass globe as shown.
