Bowling’s popularity in the United States was just taking off in the 1890s. In addition to its recreational value, bowling was seen as a comprehensive form of exercise. Unfortunately, bowling alleys required a great deal of physical space. Enter the centrifugal bowling alley, the roots of which stretch back to 1885 Berlin. The loop design used centrifugal force to propel the ball toward the pins. Americans got their own version a few years later, the goal of which was to bring bowling into residences. Perhaps a precursor to the private bowling alley?
