Check out the website of Old Custom Cruisers, a car club based in Bristol, Tennessee. They own two vintage Ahrens-Fox pumpers—one from Chicago and another from Maywood, Illinois. This particular pumper is a rare 1925 model, known as the Ahrens-Fox Model JS4, capable of delivering 750 gallons per minute. The pump has been used for various fire suppression scenarios, with recorded usage including: 750 gallons at 120 psi for 6 hours, 375 gallons at 200 psi for 4 hours, and 250 gallons at 250 psi for 2 hours. These figures give a sense of how this historic unit was operated under different pressure conditions. Under the hood, the engine features a 6-cylinder design with two spark plugs per cylinder, a dual ignition system using both a magneto and distributor, and mechanical brakes. It also has a 3-speed manual transmission and a spring suspension system—typical of early 20th-century fire apparatus. One notable feature of the pump is the "Ball," or pulsation chamber, which helps smooth out the water stream as it exits the nozzle. The tall chamber on the front of the pump helped maintain vacuum on the intake side. This design remained largely unchanged from 1915 until 1952, making it a classic example of early fire truck engineering. This specific pumper was originally used by the Maywood Fire Department in Illinois and was manufactured by Ahrens-Fox in Cincinnati, Ohio. It’s now part of the collection of Old Custom Cruisers, preserving a piece of fire-fighting history. Old Custom Cruisers photo Old Custom Cruisers photo Thanks, Dennis.
