Patent agency Haseltine, Lake & Co. was recorded as being at address 7 & 8, Southampton Buildings, London, England, and 60 Wall Street, NYC, 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]

Signature on diagrams of Patent US-1916-1283448.

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.
