IMPROVEMENTS IN STENCH TRAPS
Year: 1871

page_text: LETTERS PATENT to William Temple, of the Borough and County of
Newcastle-upon-Tyne, Builder, for the Invention of "IMPROVEMENTS
IN STENCH TRAPS."
Sealed the 14th June 1872, and dated the 27th December 1871.
PROVISIONAL SPECIFICATION left by the said William Temple at
the Office of the Commissioners of Patents, with his Petition, on
the 27th December 1871.
I, WILLIAM TEMPLE, of the Borough and County of Newcastle-upon-
Tyne, Builder, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN STENCH TRAPS," to be as follows:-
This Invention relates to improvements in stench traps for the
purpose of preventing sewer gases from entering dwelling houses and
other places, as may be desired.
The apparatus consists of a vessel of iron, earthenware, or other
suitable material, open to the air at the top; this vessel has pipes

page_text: attached to it at opposite sides; these pipes curve upwards from and
then at right angles to the parallel sides of the vessel, somewhat in the
form of the letter S. The under side of the curved pipes at the top end
being higher than the top side of the curved pipes where they enter the
central vessel; two stench traps are thus formed with a ventilator
between them, the one being an inlet to and the other an outlet from the
central vessel. The lower end of the inlet pipe is arranged nearer to
the bottom of the central vessel or chamber than the lower end of the
outlet pipe, the relative hight of the top ends of the pipes being suited
to the inclination of the sewer to which the apparatus is applied. The
inlet trap is placed next to the house, and the outlet trap next to the
main sewer.
A tray is placed at the bottom of the central vessel or
chamber to receive any sediment that may collect, a grating being
arranged above the tray at a sufficient hight to be above the passages
to the curved pipes to prevent soil or other substance from rising to
the surface of the water in the central vessel. The tray and grate can
be removed to clean the trap, and on the top of the inlet pipe there is a
junction, to which a pipe can be attached to flush the traps and sewers
when required.
This apparatus can be applied to any existing pipe drains (as it can
be made in all sizes suitable for various sized sewage pipes) without
disturbing the internal arrangements of the house drainage; the top of
the central vessel may be carried up to the surface and covered with a
basket of charcoal, or with an open grate.
་
SPECIFICATION in pursuance of the conditions of the Letters Patent, a
filed by the said William Temple in the Great Seal Patent Office
on the 26th June 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TEMPLE, of the Borough and County of Newcastle-upon-Tyne, Builder,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of December, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,

page_text: pipes b and c, at the top ends 6' and c¹, being higher than the top side
of the curved pipes where they enter the central vessel, two stench
traps are thus formed acting at different levels with a ventilator between
them, the one being an inlet to and the other an outlet from the central
vessel a.
The lower end of the inlet pipe 6 is arranged nearer to the
bottom of the central or intermediate vessel or chamber a than the lower
end of the outlet pipe c, the relative height of the top ends of the pipes b
and c being suited to the inclination of the sewer to which the apparatus
is applied. The inlet trap b¹ is placed next to the house and the outlet
trap c¹ next to the main sewer. A tray d is or may be placed at the
bottom of the central vessel or chamber a to receive any sediment that
may collect, a grating e being arranged above the tray d, at a sufficient
height to be above the passage to the curved pipes b and c, to prevent
excreta or other substances from rising to the surface of the water in the
central vessel a. The tray d and grate e can be removed to clean the
trap, and on the top of the inlet pipe 6 there is a junction 62, to which a
pipe can be attached to flush the traps and sewers when required.
The dotted line 1, 1, shows the normal level of the water in the trap.
The dotted line 2, 2, shows the level of the water if the pressure in the
outlet pipe c forces the water down; and the dotted line 3, 3, shows the
level of the water before the sewer gas can enter the house through the
pipe b, previous to which it can escape from the top of the intermediate
vessel or chamber a into the outer atmosphere.
Figure 4 shows a longitudinal vertical section of a double-action stench
trap made of earthenware, and constructed with two dipping surfaces b'
and c¹ in accordance with my Invention. In this arrangement of stench
trap the tray previously described is dispensed with, and the air or
sewer gas is arranged to escape from the central or intermediate vessel
or chamber a, by means of a pipe or pipes a¹ connected to the upper
part thereof.
The other parts which correspond with those of the
apparatus previously described, are marked with similar letters of
reference to those shewn at Figure 2.
The improved stench trap or apparatus arranged in accordance with
my Invention can be applied to any existing pipe drains (as it can be
made in all sizes suitable for various sized sewage pipes) without dis-
turbing the internal arrangements of the house drainage, and the top
of the central vessel or chamber a may be carried up to the surface and

page_text: be covered with a basket containing charcoal, or with an open grating
as may be desired.
Having thus described the nature of my Invention, and the manner
of carrying the same into practice, I would have it clearly understood
that I do not confine myself to the exact details herein-before described
so long as the main features or character of my Invention are retained;
but what I claim is, the improved arrangement and construction of
stench traps or apparatus, in which two dipping surfaces b¹, c, are
arranged to act at different levels for cutting off the passage and allowing
the escape of the sewer gases, combined with a central or intermediate
ventilating chamber a, which also facilitates the cleansing of the trap
when required, the whole acting substantially in the manner and for
the purpose herein-before described and shown in the accompanying
Drawings.
In witness whereof, I, the said William Temple, have hereunto
set my hand and seal, this Thirteenth day of June, in the
year of our Lord One thousand eight hundred and seventy-
two.
WILLIAM TEMPLE. (L.S.)
