Today in Wheeling History: September 9--David E. Brockett of Wheeling was granted U.S. patent number 142,673 for his improved railway switch design, which featured debris-clearing holes and an adjustable shaft to accommodate various rail lengths, enhancing efficiency and maintenance (1873).
David E. Brockett invented an improved railway switch, which was granted U.S. patent number 142,673 on September 9, 1873. Railway switches were crucial for allowing trains to change tracks.
Brockett's design featured a bedplate with strategic holes. These openings allowed snow, ice, and debris to fall through, preventing obstructions that could hinder the switch's operation. He also developed a new mechanism for operating the switch components. This system used a horizontal shaft running alongside the track, equipped with handles for manual operation. When turned, this shaft moved both the switch rails and a component called the tongue.
A key innovation in Brockett's design was the adjustable nature of part of the shaft. This feature allowed the switch to accommodate rails of varying lengths without requiring custom cutting or fitting. Additionally, Brockett incorporated a specially designed jointed rod to connect the shaft to the tongue. This rod's limited flexibility enhanced its performance and reliability.
Compared to his previous design, Brockett's new switch was more cost-effective and efficient. The holes in the bedplate made it easier to maintain by reducing debris buildup. Its adaptability to different rail lengths simplified installation and increased versatility. These improvements collectively made Brockett's railway switch a significant advancement in railroad technology, offering practical benefits for train operations and maintenance.
