Abstract

122,600. Bodman, W. L. Aug. 31, 1918 Supporting.-An electric-lamp holder is provided with an electro-magnet for holding it on an iron support, consisting of a core f surrounded by a coil k and formed with a flange g which abuts against a rib c on an iron casing b. The lower end i of the casing forms the second pole of the magnet and is threaded to receive a non-magnetic ring h. The coil k may be connected with the spring contacts m, n in series or parallel.
