Description:

This is the first patent for a machine to produce a stippled (matte) finish on silverplate. A rotating wire brush stipples the item to be plated, and when the item is plated the stippled surface has a frosted appearance. The plated article can, if desired, be treated with the wire brush a second time, which has the effect of brightening the surface. This patent marks a notable advance in producing decorative silverplate but the patent proved to be too easy to evade: the assignee company, which advertised this finish as "Satin Finish Silver Plated Ware", was incorporated in 1870 but only lasted for a year or two past that time. The company president was Samuel F. B. Morse (creator of Morse code), and General Joseph Hooker was vice president. M. H. Bright was the treasurer. The company was located at 10 Maiden Lane in New York City. The September 25, 1871 term of the New York Superior Court granted an order in "The Lippiatt Silver Plate Company vs. Thomas Lippiatt et. al." We do not know anything more about that order, but it does confirm a connection between Thomas Lippiatt and the Lippiatt Silver Plate company.
