Rivets
In 1872 Levi Strauss received a letter from Jacob Davis, who had been making riveted clothing for miners in the Reno area. Davis had no money to file for a patent and offered Levi Strauss a deal if he would pay for the patent. Levi Strauss began to make copper-riveted ‘waist overalls’ (as jeans were then known).
In 1886 Levi’s ‘Two Horse Brand’ leather patch, showing the garment pulled between two horses to prove its strength, was first used.
By 1890 lot-numbers were being used for Levi products: 501 was assigned to copper-riveted overalls.
In 1902 two back pockets were added.
