Haseltine, Lake & Co.
Patent agency Haseltine, Lake & Co. was recorded as being at address 7 & 8, Southampton Buildings, London, England, and 60 Wall Street, New York City, USA.
We also have them located at 28, Southampton Buildings, London, England, along with further corroboration of 60, Wall Street, New York City, U.S.A.[1]
Later data gives the addresses 28, Southampton Buildings, London, England, and 55, Liberty Street, New York City, U.S.A.[2]
William Robert Lake was a founder or partner.[3]
We have a case in which William John Mellersh-Jackson, an agent within this firm, leads a patent, relative to communication from the inventor, Karl Hermann Fischer.[4]
We have a case in which William John Mellersh-Jackson, an agent within this firm, leads a patent, relative to communication from the applicant firm, Société Anonyme des Établissements Nieuport.[5]
We have a case in which William John Mellersh-Jackson, an agent within this firm, leads a patent, relative to communication from the applicant firm, American Rubber Company.[6]

Incidentally, William John Mellersh-Jackson has 369 hits on Espacenet, some merely as applicant, others as both inventor and applicant. Every case in which we have examined the original document actually indicates that he was solely a representative of Haseltine, Lake & Co., acting relative to communication from either an applicant firm or an individual inventor.
It seems this firm filed American patents as well. Though we don't find them on the roster available through 1910, the company's name can be seen signed to Patent US-1916-1283448. The 1906 roster does have a George Haseltine in New York (247 Broadway), and two Haseltines in Springfield, Missouri, any of whom might or might not be related to the firm.
