What Is This Pocket For..!?

Levi Strauss, as a young man in 1851, went from Germany to New York to join his older brothers who ran a goods store. In 1853, he moved to San Francisco to open his own dry goods business. Jacob Davis was a tailor who often bought bolts of cloth from the Levi Strauss & Co. wholesale house. In 1872, Davis wrote to Strauss asking to partner with him to patent and sell clothing reinforced with rivets. The copper rivets were to reinforce the points of stress, such as pocket corners and at the bottom of the button fly. Strauss accepted Davis's offer, and the two men received US patent No. 139,121 for an "Improvement in Fastening Pocket-Openings" on May 20, 1873.
