Pump Governor - Westinghouse Air Brake
Today, the air brake is the standard, fail-safe train brake used by railways worldwide. Early train brakes were hand operated and largely ineffective. To get higher and safe speeds, American inventor George Westinghouse brought out an air brake in 1869. Unfortunately, if a hose burst or the train broke in two the brakes on the entire train became useless. Also the brakes worked unevenly throughout the train and could cause the carriages to collide. Westinghouse introduced the automatic air brake for steam trains in 1873. Putting a quick-action triple valve and an auxiliary reservoir under each vehicle ensured independent braking power and the automatic application of the brakes on the whole train. The pump governor shown in this late 19th c illustration acts as an automatic throttle valve to maintain the desired system air pressure

17"x15" (43x38cm) Premium Frame
FSC real wood frame with double mounted 10x8 print. Double mounted with white conservation mountboard. Frame moulding comprises stained composite natural wood veneers (Finger Jointed Pine) 39mm wide by 21mm thick. Archival quality Fujifilm CA photo paper mounted onto 1mm card. Overall outside dimensions are 17x15 inches (431x381mm). Rear features Framing tape to cover staples, 50mm Hanger plate, cork bumpers. Glazed with durable thick 2mm Acrylic to provide a virtually unbreakable glass-like finish. Acrylic Glass is far safer, more flexible and much lighter than typical mineral glass. Moreover, its higher translucency makes it a perfect carrier for photo prints. Acrylic allows a little more light to penetrate the surface than conventional glass and absorbs UV rays so that the image and the picture quality doesn't suffer under direct sunlight even after many years. Easily cleaned with a damp cloth. Please note that, to prevent the paper falling through the mount window and to prevent cropping of the original artwork, the visible print may be slightly smaller to allow the paper to be securely attached to the mount without any white edging showing and to match the aspect ratio of the original artwork.

EDITORS COMMENTS
This print captures the intricate machinery of a Pump Governor - Westinghouse Air Brake, showcasing the evolution of train brakes throughout history. In the early days, hand-operated brakes proved largely ineffective and posed significant safety risks. However, American inventor George Westinghouse revolutionized railway transportation with his introduction of the air brake in 1869. While this innovation allowed for higher speeds and safer journeys, it was not without its flaws. A burst hose or a broken train rendered the entire braking system useless, leading to potential disasters. Moreover, uneven braking throughout the train often resulted in dangerous collisions between carriages. To address these issues, Westinghouse introduced the automatic air brake for steam trains in 1873. This groundbreaking development featured an auxiliary reservoir and quick-action triple valve under each vehicle, ensuring independent braking power and automatically applying brakes to the entire train when necessary. The pump governor depicted in this late 19th-century illustration played a crucial role as an automatic throttle valve that maintained desired system air pressure. Its presence symbolizes how technological advancements have transformed railways worldwide by providing fail-safe measures and enhancing passenger safety. Sheila Terry's remarkable photograph serves as a testament to George Westinghouse's ingenuity and his contribution to modernizing railway systems globally through his invention of the automatic air brake.
