If It's Something Broken Think of "THERMIT" Then wire or send particulars giving full dimensions of the break to our nearest office. We do the rest. Sternposts, rudder frames, connecting-rods, crank-shafts, crossheads and other such sections too numerous to mention have been saved and returned to service in a few hours. A permanent repair is assured, as Thermit upon reaction produces liquid steel at a temperature of 5000° F. When this liquid mass is poured into a mold surrounding the broken parts it melts up the ends of the seotions and amalgamates with them to form one solid mass when cool. The whole story is told in our pamphlet No. 2928 and "Reactions.” Get this literature and keep it for reference.
