The Optimus,
pride and joy of plumber and writer SS Hellyer, was a direct
development of the Bramah. The complex mechanism was
tastefully hidden in the mahogany throne, and although it probably
worked better than the Bramah, the Optimus scarcely represented any
great advance in technology. Hellyer wrote in 1877:
There is no water-closet equal to a good valve closet---perfect
in all its details---especially ... for private use in good
houses ... the excrement falls into about a gallon of water,
and directly the closet-handle is pulled the contents of the
basin (every vestige of it) are sent with some force through
the closet-trap to the regions below... .
