Calendar of Patent Records

    Abstract

    January 27, 1778.—One of the many improvements in the water-closet was due to Joseph Bramah, who was granted a patent for his ‘valve’ closet on Jan. 27, 1778. Bramah's was not only the pioneer in this type of closet, but it also remained superior in its action to all the many inventions in the same class that followed it. The modern water-closet was first described by Sir John Harington in his “Metamorphosis of Ajax,” published in 1596, many years before it came into general use.
