Piano historian Daniel Spillane described that this patent was for "a number of ideas and inventions relating to uprights and squares… and a number of lesser improvements which came to nothing", but considered the upright action significant because it "outlined many ideas afterward claimed by Wornum… in England", referring to an 1842 patent by this manufacturer that Edgar Brinsmead dubbed the "tape-check action" in the 1879 edition of his History of the Pianoforte, in which the last claim was for methods coupling the damper and hammer.
