German Patent 19222

Granted in 1882 to Johann Wilhelm Schunk of Brunndöbra-Klingenthal, this is the earliest patented example I have found of a harmonica that uses a slide at the front of the instrument to select one of a pair of reedplates. Unlike modern slide assemblies, this one does not appear to be spring-loaded, but has a button on each end to push the slider from side to side:

Again, there was no specific mention of th potential for chromatic playing in the text of the patent, but this could be easily achieved by using one reedplate tuned in C and another in C#.

Schunk was another well established family name in the Klingenthal harmonica trade, but I do not know if this particular design was ever commercially marketed.
