Abstract

246,535. Igranic Electric Co., Ltd., Curtis, A. H., Wright, S. R., and Brunning, E. J. Sept. 1, 1924. Addition to 205,013. Transformers.-The primary and secondary windings 1, 2 of the intervalve transformer described in the parent Specification are wound on tube formers 4, 5 which project from the ends of the windings and abut together, so as to leave an air gap between the windings. The diameters of the windings are made large relatively to their axial lengths, in order to reduce the selfcapacity of the windings. The core 3 is built up of rectangular laminae, each of which is cut across at one point, so that it may be opened out threaded through the coils, and then closed again. The cuts 3<a>, 3<b> of alternate laminae are arranged at different points of the magnetic circuit. The terminal board 7, core 3, and windings are supported by means of shrouding plates 9 in the form of iron or brass stampings, provided with internal supporting feet 14. The sides of the plates are bent over at 13 to engage edge bands 15 of copper or brass, which are insulated from the core and serve to complete the enclosure of the transformer. The ends of the windings are connected to spring plunger terminals 6, mounted on the terminal board 7. One form of terminal comprises a plunger 19 mounted in a cylindrical body 20, the lead being inserted through transverse holes 22, 23 in the plunger and body and held firmly in place by a spring 21.
