McChesney's patent firstly "relates to an improvement in the construction and arrangement of the key-board of a musical instrument, whereby the manipulation of the keys is rendered much easier than on the ordinary keyboard; and it consists in the arrangement of the keys, all being uniform in size and shape, in two banks, those of the lower bank having a raised playing part behind and above the keys of the second key-board, giving the appearance of a third bank, while, in fact the key-board is that of a single-bank instrument." (Patent Number 161,806)
