Steam Feed Water Trap – Henry Creamer – 1988

Details of the Patent

Henry Creamer was issued U.S. Patent #376,585 or #376,586 (there seem to be discrepancies depending on the source) on January 17, 1888. The invention was a system for automatically and efficiently draining condensed water from steam pipes and returning it to the boiler.

  • The Invention: The “Steam Trap and Feeder” was a device designed to collect condensation from steam lines and use the pressure of the steam itself to force the water back into the boiler. This process was far more efficient than previous methods that required the water to be manually drained or pumped.
  • Key Features: The core innovation was a complex system of floats, valves, and levers that automatically opened and closed, allowing the condensed water to be fed back into the boiler without any manual intervention. This not only conserved water but also maintained a constant water level in the boiler, which was crucial for its safe and efficient operation.
  • Problem Solved: This invention addressed a major problem in industrial settings that relied on steam power. Wasted condensation led to a loss of energy and required constant manual labor to replenish the boiler’s water supply. Creamer’s device automated this process, making steam engines and industrial machinery much more efficient.

Significance of the Invention and Inventor

Henry Creamer’s patent, while technical in nature, was a significant contribution to the industrial efficiency of the late 19th century.

  • Impact on Industry: The invention contributed to the improved performance of steam engines and factories, helping to make industrial processes more reliable and cost-effective.
  • Legacy as an African American Inventor: As a Black inventor in the 19th century, Henry Creamer’s ability to secure a patent for a complex industrial device is a testament to his engineering skill and perseverance. His work is part of the historical record that documents the crucial but often-overlooked contributions of African American innovators to American technology and industry.
