Polishing safety deposit boxes

9/8/1903

On September 8, 1903, Emil A. Strauss was granted a patent for his improvement on the safety deposit box. According to his application, until his invention, the entire safety deposit box had to be removed in order to polish it, which meant the owner had to be present. He states that his invention allows for “boxes with removable fronts, so that they may be polished . . . without disturbing the renters.”
