A Stick, a Freezer, and the Summer of 1923

Frank W. Epperson was an Oakland teenager when he accidentally left a glass of soda pop and a stirring stick on his porch on a cold California night. By morning, he had discovered something that would become one of the twentieth century's most universally loved treats. That eureka moment, born from the intersection of accident and curiosity, led him to patent his frozen confectionery in August 1924.

U.S. Patent US1505592 captures a pivotal instant in American industrial history. The Patent Office drawing sheet, dated 1924-08-19, shows Epperson's precise technical vision: the simple stick, the cylindrical form, the measured angles and labels that would transform a playground novelty into a commercial product. What strikes you about this document is its clarity of purpose. There are no flourishes, no marketing language, just the honest geometry of an invention that emerged from observation and experimentation.

The 1920s were electric with invention. Radio was reshaping how Americans consumed information; automobiles were becoming accessible to the middle class; mass production was remaking manufacturing itself. Into this ferment came Epperson's popsicle, a democratizing confection that cost mere pennies and required only freezing water and sugar. The patent drawing is a window into that era of optimism, when a teenager's backyard experiment could become a patent, and a patent could become a cultural phenomenon.

This reproduction honors the original Patent Office composition without alteration or cropping. Every line, label, and signature remains as filed, printed on archival matte paper that will preserve the image for decades.
