Henry Billings Brown,
Union Edge Setter Company v. Keith…
“ By erasing the paragraph immediately before the words, 'What I claim as my invention is,' and substituting therefor the following: 'The combination of ten finger-rest, D, with the burnishing tool and the rest for the face of the sole is the main feature of my invention; all the other points of novelty in my machine also relate to new combinations of old elements.' This also would indicate that the rest for the face of the sole was something distinct, both from the finger-rest and from the burnishing tool, which is impossible, as it must necessarily form a part of one of them. ”
