1883 William Mather, while on a visit to the United States, secured the sole rights from Frederick Grinnell to market the Grinnell automatic sprinklers in all parts of the world except North America. Initially through a sub-licence to the firm of Dowson and Taylor and then through Mather and Platt itself, he used this event to mark the beginning of yet another side of the firm's activities, the foundation of the Fire Department.
1884 Mr. Ralph Dowson in partnership with John Taylor established the firm in Bolton, which was the first to introduce the automatic fire-extinguishing system.
1887 Patent sealed, week ending 17 May: Mr. Ralph Dowson and John Taylor of Bolton, for improvements in automatic fire protection sprinklers.[2]
