CHAPTER XXV. STRUCTURAL AND PLATE MILL.
After the steel plant was completed and doing splendid work, and well knowing the want and importance of a good structural mfll, I turned my attention to that subject. At that time the flanges of the beams and channels were so narrow and the angle of the flanges so great that it was difficult to construct sections that had to be riveted to¬ gether; this was not only embarrassing to the engineer, but was an impediment in the advancement of his profession, and any difficulty that stands in the way of progress in any Une of business should, if possible, be overcome. Con¬ sequently, I took up the subject of structural material and had drawings made of beams and channels, with wider and Ughter flanges and with less angle, so that they could be punched without difficulty and be riveted together readily. I also designed a miU and rolls that would roll them out of a square steel ingot. In fact, the sections and manner of rolUng standard shapes that I then proposed were practi¬ cally what is being done at the present time.
I showed the whole scheme to some of our ablest engineers, and they indorsed it most emphatically, and urged me to get the Bethlehem Iron Company to go into the business. One of the oldest and ablest, Charles Macdonald, said that if they would, and would make shapes of sections such as I showed, he would put up at Bethlehem a structural machine shop for the manufacture of members of bridges and build¬ ings and equip it with tools, and the conveniences for han¬ dUng and faciUtating the work, that would surpass any
