English patents listed by Bennet Woodcroft for patent granted from March 2, 1617 to October 1 1852. I will see if I can find the American patents next time I am at 310 Prospect Street.

From the Bennet Woodcroft Alphabetical Index of Patentees of Inventions  (1854) reprinted
1969 by Evelyn, Adams & Mackay Ltd, London.:

Hawkins, John Isaac.  Patent # 7142. 4th July 1836. Subject matter: "Manufacturing iron and steel."

 (Between 1800 and 1847, John Isaac Hawkins is listed as granted twelve patents of many different subject matters, including the above and one other concerning iron processing:
# 7194, 28th Sept. 1836, "Blowing-pipe of blast furnaces and forges."}

Sanderson, Charles.  Patent # 7828. 11th Oct. 1838. Subject matter "Process of melting iron ores."

(Note the date of 1838 instead of 1839.  If an error, or an omission of a different patent in 1839 it is Woodcroft's, not mine. Yet if Woodcroft's, it was not caught by A.A. Gomme (Transactions of the Newcomen Society vol. 13, 1932-33, pp. 159-164 or by the "staff of the National Reference Library of Science and Invention" whose list of errors and additions of omitted patents was printed in an appendix at the beginning of the 1969 edition. The other two patents Woodcroft listed for Charles Sanderson were:  # 5693, 4th Sept. 1828, "Making sheer-steel" and # 10,9921, 4th Nov. 1845 , "Combining steel and iron into bars for wheel-tires, and for other purposes.)

Gurlt, Adolf Frederick is listed only for patent #13, 283, 10th Oct. 1850, "Extracting silver from argentiferous minerals."

(Since Woodcroft's list was published in 1854, it would not include a patent granted in 1856. Gurlt's name looks German, but not exclusively.  The patent number 1679, if an English patent, would not be for 1856, since they were numbered chronologically, and were already over 10,000 in the mid 1840s. Something like 16,790 would make more sense. A very quick eyeball scan of numbers in this volume finds nothing over the 14,000s, granted in 1852.)

Frederick Yates is not listed in Woodcroft; if he was granted a patent around 1860 it postdated this compilation. 

Woodcroft's list was also published in two other forms, chronological and by subject matter, but I don't have those volumes.
