Excerpt from Booth's Patent Steel Tread, Duplex Steel Ad Iron Rails for Railways: Their Manufacture Explained, and Merits DiscussedIt will be seen at a glance, that the rail consists of an iron base with a steel cap, united to the base, not by bolts, screws or rivets, but simply by clamping. The iron bar is rolled at the required form and weight, after which the steel cap, hav ing been rolled of the proper form and length, is properly tempered and placed upon the cold iron base. The two are then passed through the Compressing machine, which presses the cap down upon the base and clenches in its side. A good fit and'a fast bold are thus obtained, with a powerful shrink age.TO remove the steel cap for refitting or other purposes, the iron base is firmly secured, and by a hook on each side of the cap a separation is formed at one end, and followed through by rolls the entire length of the rail.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
