IMPROVEMENTS IN WATER CLOSETS
Year: 1880

page_text: LETTERS PATENT to Daniel Thomas Bostel, of 18, Duke Street, Brighton, in
the County of Sussex, for an Invention of "IMPROVEMENTS IN WATER
CLOSETS."
PROVISIONAL SPECIFICATION left by the said Daniel Thomas Bostel at
the Office of the Commissioners of Patents on the 11th October 1880.
DANIEL THOMAS BOSTEL, of 18, Duke Street, Brighton, in the County of Sussex.
"IMPROVEMENTS IN WATER CLOSETS."
This Invention has for its object improvements in water closets, and is applicable
to closets such as are described in the Specification of a former Patent granted to
me, No. 1412, in the year 1877. In these closets the basin is cleansed by a flush
of water driving its contents over a lip, whence it passes by a channel into a
vertical trunk. This trunk is closed at the top by a cover easily removed, and
terminates at the bottom in the U trap of the closet. The vertical trunk I call a
forcing trunk, as it is adapted to receive a piston, by means of which the closet
drain if it become stopped can be forced, and the obstruction driven forward.
According to my present Invention I arrange the forcing trunk at the front of the
closet basin, and sufficiently to the side to be out of the way. The lip also of the
basin is at the front, whilst the flushing water is admitted at the back. The water
drives the contents of the basin over the lip, and a very short lateral channel then
delivers it into the forcing trunk. The water for flushing I admit through a spout
like arm passing out from the back of the basin with an easy curve, so that the
water entering by this spout sweeps with its velocity unchecked over the bottom of
the basin and effectually cleanses it. A small quantity of water also I admit by
the scrole forming the upper edge of the closet basin to remove any specks of soil
which may be out of the reach of the main flush. A small pipe serves to supply
the water to the scrole, and this pipe I cause to enter the main pipe just below the
valve; it then acts also as an air pipe to ensure the emptying of the main pipe
and to prevent shock to the supply valve where this is at some distance from the
closet.
By preference I form all these parts, the closet basin, the forcing trunk, the
U trap, and the water supply spout in one piece, and of earthenware.

page_text: flush of water or flushing material has unobstructed and directly free passage with
its velocity unchecked to the excreta or refuse to be washed from the basin or
receiver into the outlet.
Secondly. Supplying the water or flushing material to the scroll for washing the
sides of the basin by means of a small independent pipe projecting into the inlet
pipe below the valve, for the purposes described.
Thirdly. Placing the forcing shaft or trunk on either side of the front of the basin
or receiver, so as to give iminediate access to and means of cleaning the closet or
forcing or clearing the soil pipe or drains.
Fourthly. The general arrangement and construction of water closet apparatus
forming additions to or improvements on my former Letters Patent, substantially
as described and represented in the annexed Drawings.
In witness whereof, I, the said Daniel Thomas Bostel, have hereunto set my
hand and seal, this Ninth day of April, in the year of our Lord One
thousand eight hundred and eighty one.
DANIEL THOMAS BOSTEL. (L.S.)
