What were the American popsicles originally called?

Like many classic American treats—potato chips, chocolate chip cookies—Popsicles are claimed to have been invented unintentionally. As the story goes, in 1905, an 11-year-old boy named Frank Epperson (August 11, 1894 – October 22, 1983) unintentionally invented the popsicle when his cup of soda with a stick it in was left outside overnight and froze.

He decided to call his invention "epsicles," a combination of his name and the word "icicles." Many years later, when he finally patented the frozen treat, his children talked him into renaming it "popsicles," because to them, the treats were "pop's icicles."
