Description: |
| This patent gives improvements to the inventor's 1813 patent X1,997. This patent was litigated in Earl v. Page, 6 N.H. 477, 26 Am.Dec. 711 (N.H., 1834). According to a research paper from Old Sturbridge Village, Earl's shingle machines of this era could cut about a dozen shingles per minute. By the 1830s his revised designs could cut as many as sixty shingle per minute. That article says that they could not find any information on the design of Earl's shingle mills. But see the link for patent specification and partial drawings.From the 1886 book, "Federal Decisions, Vol. XXV. Patents, Copyright and Trade-marks", this patent was involved in the following litigation. "Substitution of a new element in an old combination, Earle v. Sawyer, 4 Mason, 1." Elsewhere it mentions "Earl v. Page. Shingle-machine. Abandonment. Not, failure of consideration. 6 N. H. 477. Earl v. Sawyer. Shingle-machine. Want of novelty. Patentability. Drawings are part of specification. Rule of damages. 4 Mason, 1; 1 Robb, 490." |
