Elevator Systems of the Eiffel Tower, 1889
"Elevator Systems of the Eiffel Tower, 1889" by Robert M. Vogel is a scientific publication written in the late 20th century, specifically focusing on the groundbreaking elevator technology used in the iconic Eiffel Tower. The book traces the evolution of powered passenger elevators from their inception in the mid-19th century, culminating in the innovative systems installed in the Eiffel Tower for the 1889 Paris Exposition. It delves into the engineering challenges faced in terms of capacity, safety, and the unique structural design posed by the curvature of the tower’s legs. The book extensively details the various elevator systems developed for the Eiffel Tower, primarily focusing on the Otis system, which was hydraulic and designed to accommodate the tower's incline. Vogel discusses the multiple bidder attempts and the final decision to employ the Otis design despite initial hesitations about its complexity and noise. Additionally, the book examines two other systems—the Roux, Combaluzier, and Lepape system for the lower levels, enhancing the overall functionality of vertical transportation within the tower. Through thorough research and technical specifications, Vogel illustrates not only the mechanical innovations but also the broader significance of these elevator systems in the context of architectural advancements and public accessibility to monumental heights.
The Engineering Contributions of Wendel Bollman
"The Engineering Contributions of Wendel Bollman" by Robert M. Vogel is a historical account published as part of the Smithsonian Institution's Bulletin series in the mid-20th century. The book primarily explores the life and significant innovations of Wendel Bollman, a self-taught civil engineer known for developing the Bollman truss, the first system utilizing iron as the principal material in bridge construction for American railroads. The work details the transformative impact of Bollman's contributions during the burgeoning era of railroad development in the 19th century. In this detailed examination, Vogel chronicles Bollman's early career and his rise within the Baltimore and Ohio Railroad, elucidating the technical aspects and challenges he faced while pioneering iron bridge construction. The book discusses notable projects, including the first all-iron Bollman truss built in 1850 and its applications in various locations, significantly enhancing the efficiency and safety of railroad infrastructure. Through comprehensive analysis, Vogel not only highlights Bollman's key achievements but also places his work within the broader context of 19th-century engineering practices, illustrating his lasting influence on modern structural engineering.
Tunnel Engineering: A Museum Treatment
"Tunnel Engineering: A Museum Treatment" by Robert M. Vogel is a scientific publication that provides an in-depth exploration of the evolution of tunneling techniques, particularly from the late 19th century to the early 20th century. The book serves as a historical account, detailing significant advancements in tunnel engineering, including both soft-ground and rock tunneling methods used throughout history. It highlights the transition from primitive excavation techniques to more sophisticated engineering practices, crucial in establishing tunnel engineering as a key discipline within civil engineering. In this comprehensive treatment, Vogel describes models constructed for the Hall of Civil Engineering at the Smithsonian Institution to illustrate pivotal tunneling technology developments. The book covers historic examples such as the construction of the Hoosac Tunnel and Brunel's Thames Tunnel, focusing on the engineering challenges and innovations that emerged during their construction. Each model represents either a fundamental new concept or an important early application in tunneling, demonstrating how techniques evolved to address the complexities of working in various geological conditions. The text ultimately emphasizes the integral role that these engineering feats played in modern infrastructure development and the continuous refinement of tunneling methods in response to earthly challenges.
