. Electrical world. f Transformer Design. The fact that technical literature used in our colleges can be effec-tively supplemented by the assistance of manufacturing concerns wasstrikingly illustrated recently in a transaction between the Universityof Iowa and the Fort Wayne Electric Works, Fort Wayne, Ind. Inclass room work an instructor is often handicapped in lecturing onelectrical design by lack of suitable illustrating matter on the subjectunder discussion. This applies particularly to modern standardpractice, which is often lacking in up-to-date technical supply this omission at the University of Iowa, correspondencewas opened by Prof. Spinney with the Fort Wayne Electric Works,regarding the possibility of effectively illustrating transformer con-struction. The type A oil-insulated Wood transformer was selectedas a suitable preferred design for illustrating shell type constructionas applied to lighting transformers. In order to obtain the most satisfactory results in class room work,. CROSS-SECTIOX OF MODEL TR.\XSF0RMER. a full-sized model of the cross-section of the transformer was con-structed and mounted in a suitable glass-covered case for suspendingon the class room walls. An illustration of this cross-section modelis shown herewith. It will be noticed that nearly all of the pointsof construction which would be considered in economical commercialdesign are effectively shown in this illustration. The cross-section was taken across the coils through the center ofthe core. In constructing this model a thin section of coils andcore was mounted on a board cut to conform with the outlines ofsuch transformers. Around the edge of this board was built up areproduction of the section of the transformer case the same thick-ness as the section of core and coils. Felt gaskets under the cover,oil within the case and other features hard to reproduce were repre-sented by the proper color paint. The dimensions of all parts andproportion of different parts w
