Abstract

[Class 88 (ii)] In a piano, particularly a miniature piano the action of which is operated by vertical tension-members or struts 2 and levers 3, the latter diverge rearwardly, either separately or in groups A, B, C, in order to accommodate the difference in pitch between the hammers 9 and keys 1, occasioned by spaces between the former, for instance at the ribs of the iron frame and at the overstrung part thereof. Additionally the rear parts of the keys may diverge.
