As a kid I was mystified why the people who made stuff for bowling alleys made this as well.

The company - American Machine and Foundry - was started in1900, and got into EVERTHING. Bikes, bowling, model airplanes, snow skis, yachts, sailboats, golf clubs, scuba equipment, and so on. They even owned Harley-Davidson for a whil. Oh, also nuclear reactors. Wikipedia notes: "The company's vast diversified output proved difficult to efficiently manage, and after suffering a series of losses, the company began to sell off most of its manufacturing operations."

Now they run bowling alleys.
