This header was fabri-cated and welded in a Chicago shop, andthe method of welding on the blank headis clearly shown. All plate for the mainbody of the header, the four tees andthe blank flange, was 7-16 in. thick. Thetees, as will be noticed, are offset fromthe centre line of the main header neces-sitating careful laying off and the flanges and the joints of thetees, as will be noticed, were welded. The method of welding on the blankbead is clearly shown. The simpleclamps shown were constructed of piecesof angle iron bolted together with onebolt, and held apart at their outer endby a metal spacer. The la
