An electric lamp stand which is made of elongated and longitudinally bored sections and characterized by a connection between two sections which is strong and relatively inexpensive with a connect that acts as a bolt rather than a screw. This electric lamp stand comprises a pair of lamp stand sections, made of wood turnings, each having a bore therethrough and both operatively abutting each other with the bores in endwise alignment and communication. This electric lamp stand distinctively includes a counterbore in one of the lamp stand sections, a first nut pressed in the counterbore, an externally threaded tube having one end screwed in this nut and having the other end extending in the bore of the other lamp stand section, and a second nut screwed on this other end of the tube and with the first nut and tube cooperativey bolting the two lamp stand sections in firm abutment with each other.
An electric lamp stand comprising, in combination, a first and a second lamp stand members made of wood turnings, each having a cylindrical bore extending therethrough, said first and second lamp stand members operatively abutting each other with said bores in endwise alignment and in communication with each other, the bore of said first lamp stand member having a first cylindrical portion of uniform diameter adjacent said second lamp stand member and a longer counterbore portion remote from the second lamp stand member and cooperatively forming an internal annular abutment shoulder at the junction with said first portion, a cylindrical metal nut having a knurled outer surface of a diameter slightly larger than that of said counterbore portion and pressed through said counterbore portion in frictional engagement with said counterbore portion and in abutment against said internal annular abutment shoulder, so as to be retained against rotation and against axial displacement within said counterbore portion, an externally threaded metal tube freely extending through said first bore portion and freely through the bore of said second lamp stand member and screwed at one end in said cylindrical nut, abutment means including a flat sided metal nut screwed on the other end of said metal tube with said abutment means abutting axially against said second lamp stand member, and electric wires extending through said metal tube and through said counterbore.
