Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.

The inventor was also an itinerant music instrument maker, specializing in pianofortes. The September 2012 issue of "Early Keyboard Journal" reportedly has an article on Christian and John Veltenair, written by Michael D. Friesen.
