Patent Drawing for a Staple Machine, 06/23/1903
On June 23, 1903, the Patent Office granted Robert K. Marple’s patent for the staple machine. In his application, he states that “it has as its primary object to produce a simplified machine … and to render the parts readily changeable in order to adapt the mechanism to the character of the work.”
On May 20, 1873, Jacob W. Davis of Levi Strauss & Co. received patent #139,121 for an “improvement in fastening pocket openings.” Davis’s improvement consisted of “the employment of a metal rivet or eyelet at each edge of the pocket opening to prevent the ripping of the seam at those points.”
In a deposition given during a patent infringement lawsuit in 1874, Davis recounts the story of how he came to first use rivets on work pants. He explains how, in January 1871, a woman asked him to make a pair of pants for her husband and to make them strong. Before working on the pants, he had been using rivets to attach straps to horse blankets, and when he noticed the rivets lying on the table, he thought to use them to attach the pockets.

In case Eisenbrandt’s spring-loaded coffin wasn’t creepy enough, on December 5, 1882 J. G. Krichbaum patented his device for indicating life in buried persons. We’re curious if this was ever successfully employed?
