IMPROVEMENTS IN APPARATUS FOR TRAPPING PASSAGES INTO SEWERS OR DRAINS."
Year: 1853

page_text: LETTERS PATENT to William Austin, of 27, Holywell Street, West-
minster, for the Invention of "IMPROVEMENTS IN APPARATUS FOR
TRAPPING PASSAGES INTO SEWERS OR DRAINS."
PROVISIONAL SPECIFICATION left by the said William Austin
at the Office of the Commissioners of Patents, with his Petition,
on the 12th November 1853.
I, WILLIAM AUSTIN, of 27, Holywell Street, Westminster, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN APPARATUS
FOR TRAPPING PASSAGES INTO SEWERS OR DRAINS" to be as follows:-
The object of this Invention is to arrange apparatus for trapping
passages into sewers or drains in such manner that the water only, as
far as may be, may pass into the drain or sewer, and the sediment or
heavier matters, and also floating matter moved by the water, may be re-
tained in the vessel or box of the trap. For this purpose there is formed a
box or vessel through which the passage into the sewer or drain passes, but
in such manner as to leave space below the upper part of such passage
and the bottom of the vessel or box, which space is to receive and retain
the heavier matters, sediment, and floating matters. Over the upper
part of the passage is placed an inverted bell or vessel with a grating
at its lower part, so as to prevent the passage of matters into the sewer

page_text: or drain with the water, except such as can pass through the perfora-
tions of the grating, and the box or vessel of the trap is covered by a
grating.
When for rain water pipes the inverted vessel may be dis-
pensed with; and when syphon pipes are used I apply a cylinder at the
upper part of the bend, having in it a float with a rod and valves so as
to indicate when the syphon has become stopped.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Austin in the Great Seal Patent Office
on the 12th May 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WILLIAM AUSTIN, of No. 27, Holywell Street, Westminster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of November, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said William Austin, Her special
licence that I, the said William Austin, my executors, administrators,
and assigns, or such others as I, the said William Austin, my execu-
tors, 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 "IMPROVE-
MENTS IN APPARATUS FOR TRAPPING PASSAGES INTO SEWERS OR DRAINS,"
upon the condition (amongst others) that I, the said William Austin,
by an instrument in writing under my hand and seal, should particu-
larly 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 William Austin, do hereby
declare the nature of the said Invention, and in what manner the

page_text: same is to be performed, to be particularly described and ascertained in
and by the following statement thereof (that is to say):
The object of this Invention is to arrange apparatus for trapping
passages into sewers or drains in such manner that the water only, as
far as may be, may pass into the drain or sewer, and the sediment or
heavier matters, and also floating matters moved by the water, may be
retained in the vessel or box of the trap. For this purpose there is
formed a box or vessel through which the passage into the sewer or
drain passes, but in such manner as to leave space below the upper
part of such passage and the bottom of the vessel or box, which space
is to receive and retain the heavier matters, sediment, and floating
matters. Over the upper part of the passage is placed an inverted bell
or vessel, with a grating at its lower part so as to prevent the passage
of matters into the sewer or drain with the water, except such as can
pass through the perforations of the grating, and the box or vessel of
the trap is covered by a grating. When for rain water pipes the
inverted vessel may be dispensed with; and when syphon pipes are used
I apply a cylinder at the upper part of the bend, having in it a float
with a rod and valves so as to indicate when the syphon has become
stopped.
Having thus described the nature of my said Invention, I will pro-
ceed to explain the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figures 1, 2, and 3, show three traps for rain water pipes which are
similar in construction, they differing only in shape; Figure 4, shows
a section of one of these traps combined with a syphon; and Figure 5,
shows a section of these traps separately. a, a, is the vessel or box
into which the end of the rain water pipe b enters. c, is the outlet to a
drain, which is considerably above the bottom of the box or vessel a, so
as to admit of heavy matters settling in the box or vessel a, and thus
prevent such heavy matters passing away. d, is a perforated plate, or it
may be a grating, through which water may pass on to the drain. The
perforated plate or grating moves on hinges at e; hence, when desired,
the box or vessel a may be readily emptied and cleansed from sediment
or accumulations. f, is a syphon or bent pipe connected with the trap

page_text: vessel a, in order to produce a water joint, and it has a covered shaft g,
through which it may be cleansed at any time with convenience, and
it may have a float and a rod to indicate when it becomes stopped.
Figure 6 shows a plan and Figure 7 a section of a gully trap for
sewers or large drains suitable for streets and other places; Figure 8,
is a section of another arrangement of smaller gully trap more suitable
for stables, wash-houses, and such like places; and Figures 9, and 10,
show two plans thereof, according as it is made circular or square.
a, a, is the box or vessel. b, is the outlet which rises from the bottom
upwards, and on its upper end it has placed over it an inverted bell c,
as shown. d, is a grating moving on axes at e, e, or the grating may
be simply fitted into the upper part of the box or vessel a, as shown at
Figure 8; and I prefer using the loose bar grating at top where car-
riages pass over the trap, in addition to a perforated inner plate f
when the traps are formed in the manner shown in Figures 8, 9,
and 10.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that I do not con-
fine myself to the details shown and described, nor do. I claim any of
the parts separately of which either of the apparatus above described is
composed; but what I claim is,-
First, the apparatus described in respect to Figures 1, 2, 3, 4,
and 5.
And, secondly, I claim the apparatus described in respect to
Figures 6, 7, 8, 9, and 10.
In witness whereof, I, the said William Austin, have hereunto set
my hand and seal, this Tenth day of May, in the year of our
Lord One thousand eight hundred and fifty-four.
Witness,
H. CARPMAEL.
WILLIAM AUSTIN. (L.S.).
