Présentation de l'éditeur
The bolt and nut industry in America started in a very small way in Marion, Conn., in 1818. In that year Micah Rugg, a country blacksmith, made bolts by the forging process. The first machine used for this purpose was a device known as a heading block, which was operated by a foot treadle and a connecting lever. The connecting lever held the blank while it was being driven down into the impression in the heading block by a hammer. The square iron from which the bolt was made was first rounded, so that it could be admitted into the block. At first Rugg only made bolts to order, and charged at the rate of sixteen cents a piece. This industry developed very slowly until 1839, when Rugg went into partnership with Martin Barnes; together they built the first exclusive bolt and nut factory in the United States in Marion, Conn. The bolt and nut industry was started in England in 1838 by Thomas Oliver, of Darlston, Staffordshire. His machine was built on a somewhat different plan from that of Rugg s, but no doubt was a further development of the first machine; Oliver smachine was known as theE nglish Oliver. As is generally the case with a new industry, the methods and machines used were very carefully guarded from the public, and this characteristic seems to have followed this industry down to the present time, judging by the scarcity of information available on the subject. Some idea of the methods which were at first employed to retain all information in the factory in which it was originated is well brought out by the following instance: In 1842, when the industry was beginning to be generally known, it is stated that aM r. Clark, who at that time owned a bolt and nut factory inN ewE ngland, and had devised a special machine for use in this manufacture, had his forging machine located in a room separated from the furnaces by a thick wall. A hole was cut through

Présentation de l'éditeur
This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
