Available in PDF, EPUB and Kindle. Book excerpt: The manufacture of locks, and a consideration of the mechanical principles involved in their construction and security, have never yet been treated with any degree of fulness in an English work. Lock-making has occupied a large amount of ingenuity, and lock-patents have been obtained in considerable number, though not always, we are satisfied, with a commensurate return for the expense incurred,--but lock-philosophy (if so it may be designated) has not been largely attended to.And yet it may safely be said that much which is both mechanically and commercially important is comprised in a lock. Every improvement in the manufacture of iron, steel, and brass--that is, in the tool-making and machine-making processes--may be made to reflect its light on the lock-manufacture; the stamping, the casting, the planing, the slotting, the screw-cutting, the polishing of metals,--all, in proportion as they are improved, impart some of their aid to the lock-maker. Then, in the finer kinds of locks, the works are so delicate as to approach to the nicety of clockwork; thereby combining the manipulative skill of a talented artisan with the rougher mechanical work of the smith. The principles of mechanical science are also appreciated by many lock-makers. The lever, the inclined plane, the eccentric, the cam, the screw, the wheel and pinion, the ratchet, the spring,--all are brought to bear on the internal mechanism of locks, frequently in many novel combinations.

This book was released on 1983 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project has been sponsored by the St. Paul district of the United States Army Corps of Engineers as a planning tool to facilitates its obligations to preserve and project the cultural heritage. More specifically, thirteen locks and dams have been investigated in order to determine their historical value. Since seven of these lock and dam complexes are currently under evaluation for hydropower conversion, historic preservation officers of Minnesota, Wisconsin and Iowa have expressed their interest in seeing the thirteen lock and dam structures be considered for a thematic group format submission to the National Register of Historic Places. Moreover, the contract was modified to include study of the Lower Dam Hydro Station and Wasteway No. 2, both of which are located in St. Anthony Falls Historic district and may be utilized for hydropower development. The location of this study area is a large one covering a stretch of approximately 239 river miles along the upper Mississippi upon which the locks and dams are located. The specific specifications of the contracts are contained in the scope of work found in the Appendix.
