AN IMPROVED STENCH TRAP
Year: 1866

page_text: LETTERS PATENT to Samuel Buxton, of Hunslet, in the County of
York, Contractor, for the Invention of "AN IMPROVED STENCH TRAP."
Sealed the 14th June 1867, and dated the 19th December 1866.
PROVISIONAL SPECIFICATION left by the said Samuel Buxton at the
Office of the Commissioners of Patents, with his Petition, on the 19th
December 1866.
I, SAMUEL BUXTON, of Hunslet, in the County of York, Contractor, do
hereby declare the nature of the said Invention for "AN IMPROVED STENCH
TRAP," to be as follows:-
My Invention has for its object the prevention of obnoxious gases rising
through gulleys, kitchen sinks, and sumph holes, from refuse water, or water
and solid matters which have passed down the waste pipe. For this
purpose, instancing a kitchen sink, I use a receiver (which may by preference
be made of earthenware) of cylindrical form having a branch tube formed
upon its lower end for the purpose of connection with the pipe from the sink.
The lower end of the receiver has the form of a cone, being reduced in

page_text: diameter for the purpose of connection with the sink pipe. The internal
formation of the ejection orifice is adapted (being lined with copper or other
suitable material) to receive a conical plug (also by preference of copper)
which fits well into it and is connected to a wire which passes through a hole
in the cover, placed over the top of the receiver; a float is placed upon this
wire at a suitable distance from the conical plug before named. The branch
tube having therefore been fixed to a part of the sink pipe in convenient
proximity to the sink itself and the lower part of the receiver connected to the
continuation of the sink pipe, upon water or other fluids or fluid and solid
matters being admitted down the sink pipe through the branch into the
receiver the float is raised, and consequently the conical plug. The
admitted contents are thus permitted to pass away; the supply ceasing the
plug descends into its place, and stench is prevented. This receiver may
equally well be adapted to gulleys for public thoroughfares, sumphs, water-
closets, and to other places where it is desired to prevent the emission of foul
air or noxious gases from receptacles.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Buxton in the Great Seal Patent Office on the
17th June 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
BUXTON, of Hunslet, in the County of York, Contractor, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of December, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Samuel Buxton, Her special licence that I, the said Samuel Buxton, my
executors, administrators, and assigns, or such others as I, the said Samuel
Buxton, my executors, 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
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED STENCH
TRAP," upon the condition (amongst others) that I, the said Samuel
Buxton, my executors or administrators, by an instrument in writing under

page_text: 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 Samuel Buxton, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
My Invention has for its object the prevention of obnoxious gases rising
through gullies, kitchen sinks, and sumph holes, from refuse water, or water
and solid matters which have passed down the waste pipe. For this purpose,
instancing a kitchen sink, I use a receiver (which may by preference be made
of earthenware) of cylindrical form, having a branch tube formed upon its
lower end for the purpose of connection with the pipe from the sink; the
lower end of the receiver has the form of a cone, being reduced in diameter
for the purpose of connection with the sink pipe. The internal formation of
the upper orifice of the ejection pipe is adapted (being lined with a seat of
copper or other suitable non-corrosive material) to receive a conical plug
(also by preference of copper) which fits well into it, and is connected to a
wire which may be of non-corrosive material, and which passes through a
hole in the cover placed over the top of the receiver; a float (also by pre-
ference of non-corrosive material) is placed upon this wire at a suitable
distance from the conical plug before named. In some cases I prefer to
make the lower portion of the float itself of conical formation, so as to fit into
the metallic seat of the ejection pipe, constituting, in fact, a combined float
and plug, the plug portion being "ground" into the seat, so as to make a
good and close fit in the manner of ordinary water cocks; or I sometimes
prefer to affix a conical non-corrosive ring on the lower portion of the
float, and "fit" it in like manner to the seat. The branch tube having
therefore been fixed to a part of the sink pipe in convenient proximity to the
sink itself, and the lower part of the receiver connected to the continuation
of the sink pipe upon water or other fluids or fluid and solid matters
being admitted down the sink pipe through the branch into the receiver
the float is raised, and consequently the conical plug; the admitted contents
are thus permitted to pass away, the supply ceasing, the plug descends into its
place and stench is prevented. This receiver may equally well be adapted to.
gullies for public thoroughfares, sumphs, waterclosets, and to other places

page_text: Figure 1 represents a side elevation of my trap, which is placed under the
sink or in other convenient position, the loose upper portion A having a
branch tube a for connection with the sink pipe, and resting on the bottom B;
the lid is shown at C, the float wire c passing through it; Figure 2 is a
vertical section of my trap showing the parts before named; letter D shows
the float having conical extremities and connected to the guide rod c; the
lower cone of the float is shown fitted with a conical ring d resting upon the
conically formed seat a¹, which is secured to the mouth or receiving portion
of the ejection pipe E, the fluid or fluid and solid matters passing down the
branch pipe a into the chamber A raise the float D and plug d, and then pass
through the ejection pipe E into the sewer, the plug then resting in its seat a¹
and preventing the escape of effluvia. Figures 3 and 4 are horizontal sections,
the former through the chamber A and branch pipe a, and the latter through
the float D and chamber A; Figures 5 and 6 show sections of my principle
applied to an ordinary street gully, a fixed earthenware or metal gridiron
being substituted for the swinging flap used in that class of gully to prevent
bulky solid matters from passing in; Figures 7 and 8 show a section and
plan of an arrangement whereby all matters that are admitted through the
street grate are carried into the sewer; Figures 9 and 10 show the sections of
my arrangement applied to an ordinary flap trap; Figure 11 is a side elevation
of a watercloset trap, the internal arrangements being identical with those
already explained; Figure 12 is an elevation of a trap contracted in length
and of proportionately greater diameter than that shown in Figure 1, adapted
to certain positions where the distance from the point of reception to the
point of discharge is limited.
Having now fully described and ascertained the nature of my Invention,
and in what manner the same is to be performed, I would have it understood
that I do not confine myself to the precise details shown and described, but
what I claim as and of my Invention is the prevention of the escape of
noxious gases from sewers in kitchen or other sinks, sumph holes, and gullies

page_text: by means of a plug resting in a seat, as shown, and in connection with a float
and guide wire.
In witness whereof, I, the said Samuel Buxton, have hereunto set my
hand and seal, this Fifteenth day of June, in the year of our
Lord One thousand eight hundred and sixty-seven.
