page_text: I, ARTHUR WAKEFIELD, of 39, Victoria Street, in the City of Westminster,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in gullies used for taking away surface
water from the streets and for analogous purposes, and its object is to provide such
a gully as will be effectually trapped in dry seasons even when the whole of the
water in the body or main portion of the gully shall have evaporated, or when
the said body has become nearly full of detritus. I make the gully of such form
that the outlet will be at all times free to act, and it will be seen that a double
trap is formed or scal effected.
In carrying out my said invention, I form or mould a gully body of the usual
shape. say, for instance, about 22 by 16 by 42 inches, and I partition off a portion
of this at one end, say, 6 inches in width, by means of a division or diaphragm
extending from the bottom upwards, and the space or chamber thus cut off I again
sub-divide into two parts or chambers by means of a second partition or diaphragm
at right angles to the first, the said second partition being placed, say, six inches
from one end, so forming a small chamber of, say, six inches square in area, and a
larger one of, say, 9 by 6 inches.
The sides or walls of the smaller chamber are carried up to the top, or nearly
so, of the gully, and a tight fitting or sealed cover is provided, but the lower portion
of the transverse partition is cut away so that water may pass under the same.
I cut away also a portion of the top of the first or main partition or diaphragm,
say, to a depth of 3 inches so that the water from the main part or body of the
gully may run over the lower portion and fill the subsidiary chambers. The usual
swan neck outlet is formed on the side of the gully opening into the side small
chamber, and it will be seen that this small chamber will remain full or nearly
so of water, even when the water in the main body of the gully is all evaporated,
and it will also be seen that the outlet is free to act even though the gully proper
be nearly full of detritus.
The larger subsidiary chamber may also be closed by means of a lid or cover
so as to prevent detritus falling therein through the main grid.

page_text: Improvements in Gully Traps.
I, ARTHUR WAKEFIELD, of 39, Victoria Street, in the City of Westminster,
Engineer, do hereby declare the nature of this 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 consists in improvements in gullies used for taking away surface
water from the streets or for analogous purposes and my gulley is so constructed
that though the whole of the water in the main body of the said gully may have
evaporated or been otherwise abstracted, the water seal or seals may still remain
effective for preventing the passage of sewer gas through such gully into the
street and moreover my improved construction will allow of the main body being
filled with detritus to within a short distance of the top without preventing the
free passage of water into the inner or subsidiary chambers hereafter described
and thence to the sewer; another advantage is that the outlet may be formed
near to the top and at one end so as to be close to the curb if desired thus preventing
breakage from the passage of a steam roller or other heavy weight.
The gully may by my invention be formed entirely of earthenware or of metal
or where brick gullies are used may have its main features built up of brickwork,
the lids or covers of the subsidiary chambers and the outlet being of other
material such as earthenware or metal. I will further explain my invention by
reference to the accompanying drawing which is a perspective view of a street
gully constructed in accordance therewith one corner of said gully being cut away
to shew the arrangement of the subsidiary chambers.
I prefer to construct my gully in a rectangular form as shewn on the drawing
but it may be circular or oval if preferred without departing from the principle
of my invention and in its manufacture I first form or mould a box or chamber A,
say, for the purposes of description, 21 inches by 18 inches by 3 feet internally,
and then, at, say, 6 or 7 inches from the end at which the outlet it attached I
build or form a transverse partition or diaphragm B extending from the bottom
to the top and dividing the gully into two parts or chambers one considerably
larger than the other. I then partially subdivide the smaller chamber by means
of a second partition or diaphragm D extending from the top to within, say,
9 inches of the bottom, this partition being about 6 or 7 inches from the side of
the gully, now consisting of a main body or chamber C having two subsidiary
chambers E and F. I form holes G G near the top of diaphragm B, or may cut
away entirely a portion of said diaphragm, and a lid H may be provided to cover
the chamber F and this may be loose or hinged to allow of cleansing. The third
chamber I cover permanently at S by means of a roof having a Stanford or
other stopper K, which could be taken out if access became necessary. Near the
top of chamber E I attach a coffee pot or similar outlet L opening into said
chamber E as shewn by dotted circle at M.
It will be seen that the water and detritus enter the main body C of gully
through the usual grating and when the water rises to the level G it passes down
into chamber F', under partition or diaphragm D, and rising up chamber E passes
into sewer through orifice M. and outlet L the heavy detritus remaining in lower
part of chamber C. It is obvious that this chamber C may become filled with
detritus up to point G without preventing the normal flow of water into sewer;
also that the whole of the water in chamber C may be evaporated without unsealing
the trapped outlet L.
I am aware that gullies have been divided into two chambers by means of a

page_text: diaphragm or partition extending upwards from the bottom as for instance is
shewn by specification and drawings attached to Letters Patent granted to Robert
Cardwell, dated 19th January, 1877, No. 250, and that double seals have been
formed in various ways but so far as I can ascertain such seals are more or less
defective when the main body of the gully is partially full of detritus.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I'
claim is:-
1. The construction of a street or surface water gully having a main body or
chamber such as C for collection of detritus, subsidiary divisions or chambers, such
as E and F, with inlet or inlets for water thereto as at G at or near top of main
diaphragm B, an auxiliary diaphragm D, and an outlet L, M, the whole arranged
substantially as hereinbefore described with reference to the drawing annexed and
for the purposes specified.
2. The hereinbefore described improved street or surface water gully arranged
and constructed substantially as set forth in the foregoing specification and as
illustrated by the accompanying drawing.
