IMPROVEMENTS IN WATERCLOSETS
Year: 1877

page_text: LETTERS PATENT to Daniel Thomas Bostel, of 19, Duke Street, Brighton, for
the Invention of "IMPROVEMENTS IN WATERCLOSETS."
PROVISIONAL SPECIFICATION left by the said Daniel Thomas Bostel at the
Office of the Commissioners of Patents on the 11th April 1877.

WATERCLOSETS."
"IMPROVEMENTS IN
This Invention has for its object improvements in waterclosets, and the improve-
ments relate to closet pans or basins, which have their outlet at one side and above
the water level maintained in the basin.
In order that such basins may be more thoroughly scoured and cleaned by water
after the closet has been used, I form all around the interior of the upper part of
the basin a hollow rim, leading into which there are two inlets, one on either side
of the outlet from the basin, or in any other position in the rim, and these two
inlets are both in connection with the water supply, so that whenever the water
supply valve is opened water passes freely by these two inlets to the interior of the
hollow rim. All around the under side of the hollow rim are a number of perfora-
tions, slotted or otherwise, through which the water escapes and scours down the
sides of the basin; the perforations or slots are made largest at the side opposite to
the basin outlet, so as to cause a strong flow of water across the basin towards the
outlet to sweep it clean of its previous contents.
The outlet from the basin opens into a vertical passage leading to an S trap
which is situated below the basin, or it might be to other trap or directly to a soil
pipe. The upper end of the vertical passage is closed by a cap or cover, which can
readily be taken off in case any obstruction has to be removed from the trap.

DANIEL THOMAS BOSTEL, of 19, Duke Street, Brighton. "IMPROVEMENTS IN
WATERCLOSETS."
This Invention has for its object improvements in waterclosets, and the improve-
ments relate to closet pans or basins, which have their outlet at one side and above
the water level maintained in the basin.
In order that such basins may be more thoroughly scoured and cleaned by water
after the closet has been used, I form all around the interior of the upper part of
the basin a hollow rim, leading into which there are two inlets, one on either side
of the outlet from the basin or in any other position in the rim, and these two
inlets are both in connection with the water supply, so that whenever the water
supply valve is opened water passes freely by these two inlets to the interior of the
hollow rim. All around the under side of the hollow rim are a number of perfora-
tions, slotted or otherwise, through which the water escapes and scours down the
sides of the basin; the perforations or slots are made largest at the side opposite to
the basin outlet so as to cause a strong flow of water across the basin towards the
outlet to sweep it clear of its previous contents.
The outlet from the basin opens into a vertical passage leading to an S or other
form of trap, which is situated below the basin, or it might be to other trap or
directly to a soil pipe. The upper end of the vertical passage is closed by a cap or
cover, which can readily be taken off in case any obstruction has to be removed
from the trap.
In order that my said Invention may be most fully understood and readily carried
into effect, I will proceed to describe the Drawings hereunto annexed.
Figure 1 is a vertical section of a closet pan constructed according to my Inven-
tion. The section is taken in a direction from front to back. Figure 2 is a plan of
the same.
A, A., is the receptacle or basin, it has a hollow rim A¹, to which water is supplied
from the closet valve by two separate inlets B, B, in order that an equal distribution
of the water may be obtained on the two sides of the pan. The water issues from
the rim into the basin by perforations, which are made larger on the side opposite
the outlet than elsewhere, in order that a predominating rush in this direction may
be obtained. In the case represented in these Figures the outlet C is at the back
and the larger perforations are at the front. The outlet C communicates with a
vertical trunk D leading to a trap E situate beneath the basin A. D¹ is a cover
closing the upper end of the trunk D, but capable of being easily removed when
necessary to clear an obstruction from the trap. A connection is provided at D³ for
an overflow pipe, together, if desired, with an air pipe leading to the open air. A
plunger worked in the trunk D will be very effective in removing stoppages.
Figure 3 is a vertical section of another closet pan constructed according to my
Invention, but differing from that above described mainly in the addition of the
partition A which brings the outlet to the front of the basin. Figure 4 is a section
of the pan taken through the middle and at right angles to the section represented
by Figure 3. In some cases I make these pans without the trap E, as already
stated.
Having thus described the nature of my said Invention and the manner of per-
forming the same, I would have it understood that I claim as my improvements in
waterclosets,―
First. The hollow perforated rim A¹ with its two inlets B, B, to ensure an equal
distribution of water to the two sides of the basin.

page_text: Second. The vertical trunk D, with its cover D¹, removeable for the purpose of
clearing away obstructions.
Third. The construction of watercloset apparatus 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 Eleventh day of October, in the year of our Lord One
thousand eight hundred and seventy-seven.
