Year: 1875

page_text: LETTERS PATENT to John Dodd, of Liverpool, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN VENTILATING
WATERCLOSETS, SOIL PIPES, AND TRAPS OF SAME, ALSO IN 'FLUSHING RIMS'
APPLICABLE TO WATERCLOSET BASINS."
PROVISIONAL SPECIFICATION left by the said John Dodd at the
Office of the Commissioners of Patents, with his Petition, on the
9th August 1875.
I, JOHN DODD, of Liverpool, in the County of Lancaster, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN VEN-
TILATING WATERCLOSETS, SOIL PIPES, AND TRAPS OF SAME, ALSO IN ⚫ FLUSHING
RIMS' APPLICABLE TO WATERCLOSET BASINS," to be as follows:-
My Invention relates, firstly, to ventilating waterclosets, soil pipes,
and traps of same, and consists in improvements upon what are known
as "complete closets," or "Jennings' basins," namely, closets that are
formed with the pan, trap, and soil pipe in one piece. In carrying out

page_text: this part of my Invention I form immediately under the pan, and
directly above the soil pipe of such "complete closet," a ventilating
orifice, being a branch with a flange, to which is bolted or otherwise
attached a flange carrying a screw union, to which union the plumber
may attach a ventilating pipe to be carried to a suitable position in the
open air, thus carrying off all noxious gases from the closet, soil pipe,
and trap. In the case of closet pans which discharge at the bottom
instead of at the side (as in the case of Jennings' basin) I form the
ventilating orifice on the top of the trap and soil pipe, and from such
orifice I lead the ventilating pipe.
My Invention relates, secondly, to providing a flushing rim to more
effectually cause the water to scour and cleanse the basins of water-
closets before described, and consists in forming such flushing rim all
round the top of the basin, the supply orifice being at the back with a
dividing partition and stop. The front of the rim is provided with a
stop so cut that the water is directed in streams to scour the basin and
drive the contents therefrom. The basin is made with a concave bottom
sufficient to retain a proper quantity of water always therein.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Dodd in the Great Seal Patent Office on 2
the 8th February 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
DODD, of Liverpool, in the County of Lancaster, send greeting.
"
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Ninth day of August, in the year 2
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs, and suc-
cessors, give and grant unto me, the said John Dodd, Her special
licence that I, the said John Dodd, my executors, administrators, and
assigns, or such others as I, the said John Dodd, my executors, 3
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the

page_text: "
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
VENTILATING WATERCLOSETS, SOIL PIPES, AND TRAPS OF SAME, ALSO IN 'FLUSHING
RIMS APPLICABLE TO WATERCLOSET BASINS," upon the condition (amongst
others) that I, the said John Dodd, my executors or administrators,
by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said John Dodd, do hereby declare
the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and
by the following statement:-
My Invention relates, firstly, to ventilating waterclosets, soil pipes,
and traps of same, and consists in improvements upon what are known
as "complete" closets or Jennings' basins, namely, closets with the
pan, trap, and soil pipe in one piece. In carrying out this part of my
Invention I form, immediately under the pan and directly above the
soil pipe of such "complete closet," a ventilating orifice, being a branch
with a flange, to which is bolted or otherwise attached a flange carrying
a pipe or screw union, to which pipe or union the plumber may attach a
ventilating pipe to be carried to a suitable position in the open air, thus
carrying off all noxious gases from the closet, soil pipe, and trap. In
the case of closet pans which discharge at the bottom instead of at the
side (as in the case of Jennings' basin) I form the ventilating orifice on
the top of the trap and soil pipe, and from such orifice I lead the
ventilating pipe.
My Invention relates, secondly, to providing a flushing rim to more
effectually cause the water to scour and cleanse the basins of water-
closets before described, and consists in forming such flushing rim all
round the top of the basin, the supply orifice being at the back with a
dividing partition and stop. The front of the rim is provided with a
stop so cut that the water is directed in streams to scour the basin and
drive the contents therefrom. The basin is made with a concave bottom
sufficient to retain a proper quantity of water always therein.
The beforegoing being the nature, object, and purposes of my Inven-

page_text: tion, I will now describe how the same may be put into practical
operation, and for that purpose I have hereunto attached a Sheet of
Drawings illustrative of my Invention.
Like letters and figures marked thereon are used to denote similar
parts. The Drawing is to the scale of three inches to the foot.
Figure 1 is a side elevation of what is known as a "complete closet,"
or Jennings' basin. Figure 2 is a sectional view, Figure 3 an end view,
and Figure 4 a plan of Figure 1.
5
Figure 5 is a side view of a closet pan discharging at the bottom:
Figure 6 is a sectional side view of Figure 5, and Figure 7 is a plan of 1
Figure 5.
Firstly. In Figures 1, 2, 3, and 4 a represents a 'a Jennings' basin or
complete closet; b, is the pan; c, the trap; d, the soil pipe; which are
all formed in one piece. Now my Invention consists in adding and
forming immediately under the pan b, and directly above the soil pipe d,
a ventilating orifice with a flange i, to which is bolted or otherwise
attached a pipe K or screw union.
In fitting the closets the plumber may attach the ventilating pipe to
the pipe k, such ventilating pipe being carried to a suitable position in
the open air, thus carrying off all noxious gases from the closet soil pipe
and trap.
In Figures 5, 6, and 7, which illustrate a closet pan which discharges
at the bottom I form the ventilating orifice / on the top of the trap d,
and from such orifice I lead the ventilating pipe k.
Secondly. In Figures 2, 4, 6, and 7 f is a flushing rim, and my
improvement consists in forming such flushing rim all round the top of
the pan b, the supply orifice g being at the back and having a dividing
partition and stop m. The front of the flushing rim is also provided
with a stop at 1, so cut that the water is directed in cross streams to
scour the basin and drive the contents therefrom in the direction as
shown by the arrows.
Having now described and ascertained 'the nature and object of my
Invention, what I claim as my Invention and secured to mo by Letters
Patent as aforesaid is,-
Firstly. In a complete closet, or Jennings' basin, the formation, use,
and application of a ventilating orifice such as h, fitted with a pipe or

page_text: as ng sustavany
forth.
Secondly. In a closet such as shown at Figures 5, 6, and 7 of the
accompanying Drawings the formation, use, and application of a
3 ventilating orifice such as h, fitted with a pipe or union such as k,
substantially in the manner and for the purposes set forth.
Thirdly. In an all round flushing rim when applied to a Jennings'
basin or other closet, providing such flushing rim with stops such as
shown at and m of the accompanying Drawings, substantially in the
O manner and for the purposes set forth.
In witness whereof, I, the said John Dodd, have hereunto set
my hand and scal, this Fifth day of February, in the year of
our Lord One thousand eight hundred and seventy-six.
