AN IMPROVED GULLY FOR DRAINS AND SEWERS
Year: 1884

page_text: We STEPHEN SMITH PHILLIPS trading as W. Phillips & Son and HENRY
FREDERICK GREEN both of 10 Baker Street, Portman Square in the county of
Middlesex Sanitary Engineers do hereby declare the nature of our said Invention
for AN IMPROVED GULLY FOR DRAINS AND SEWERS to be as follows:-
The object of our invention is to produce a gully for drains and sewers in which
all the mud grease or other matter suspended in the liquid that passes therethrough
is retained and is thence easily removed and by which the said drain or sewer is
securely trapped while at the same time we so form this gully that when required
the drain or sewer to which it is attached can quickly and easily be inspected and
a rod or other apparatus inserted therein for clearing or other purposes.
To carry out this object we form a gully or deep open mouthed box of any
suitable shape and size and of any material though for ordinary house purposes we
prefer to make this gully of glazed earthenware. In the bottom of this gully
directly below the grating or mouth thereof we form a deep recess which in bori-
zontal sectional area is slightly smaller than the gully so that a shoulder is created
on two or more of the sides thereof. A container preferably of metal is fitted into
this recess being supported therein by flanges on its upper edge which rest on the
shoulders formed in the gully and handles are fitted to two of the sides of this
container which preferably reach up nearly to the grating or mouth of the gully
and by which the said container can be lifted out and the mud grease or other
matter deposited therein is then removed. The outlet to the drain or sewer is
formed on one of the sides of the gully in which side is an aperture for the passage
of the liquid to the said drain or sewer made immediately above the shoulder
therein and the end of this outlet which is connected to the said drain or sewer is
so raised that the lower part thereof is at a higher level than the upper edge of the
aperture in the side of the gully which edge therefore forms a dip whereby the drain
or sewer is securely trapped. To enable us quickly and easily to inspect the drain
or sewer and to insert a rod or other apparatus therein when required we make
another aperture in the upper part of the same side of the gully and we so form
the upper part of the outlet that a rod or other apparatus inserted through this

page_text: aperture can pass directly into the drain or sewer to assist which operation we can
also when it is so required form a slot in the top rim of the gully opposite to this
aperture. This aperture is tightly closed by a cap which can be passed down the
mouth of the gully and fixed in a seat made therefor in this said aperture. A
convenient method of effecting this when the gully is made of earthenware is to
form this aperture of a circular shape and to let a ring into the gully through a
slot in the upper part of the projecting outlet thereof which ring exactly fits this
aperture and into which ring can be screwed a circular cap or plate by a key fitted
thereon which key can afterwards be removed. This cap or plate and the ring
into which it is screwed would in this case be made of brass or other anticorrosive
material.

page_text: We STEPHEN SMITH PHILLIPS trading as W. Phillips & Son and HENRY
FREDERICK GREEN both of 10 Baker Street, Portman Square in the County of
Middlesex, Sanitary Engineers do hereby declare the nature of our said invention
for AN IMPROVED GULLY FOR DRAINS OR SEWERS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :—
The object of our invention is to produce a gully for drains and sewers by the
which the drain or sewer shall be securely and efficiently trapped while at the same
time the said drain or sewer can quickly and easily be inspected when desired and
a rod or other apparatus inserted therein for clearing or other purposes. We can
also so form this gully that all the mud grease or other matter suspended in the
liquid that passes therethrough to the drain or sewer shall be retained in the said
gully and can thence be easily removed.
In order fully and clearly to explain our invention and in what manner the
same is to be performed we refer to the accompanying drawing.
Figure 1 is a vertical longitudinal section of one form of this our improved gully.
Figure 2 is a vertical transverse section of the same.
The gully A is a deep open mouthed box or chamber of any suitable and con-
venient shape and size and it can be made of any material though for ordinary
house or other purposes we prefer to use earthenware and especially glazed
earthenware. The outlet B therefrom to the drain or sewer C is formed on one
of the sides of the gully A in which side an aperture D is made of any suitable
size and shape for the passage of the liquid at or near the bottom of the said gully A
and the end E of this outlet B which is connected to the drain or sewer C is so
raised and formed that the lower part of the said end E is at a higher level than
the upper edge of the aperture D in the side of the gully A which upper edge
therefore forms a dip whereby the drain or sewer C is securely and efficiently
trapped. For the purpose of allowing the drain or sewer to be quickly and easily
inspected when desired and a rod or other apparatus to be inserted therein for
clearing and other purposes we raise the upper side or top wall of the outlet B
up to the top of the gully A or thereabouts as shewn at B₁ and we make
another aperture F in the upper part of that side of the said gully A in which is
the aperture D hereinbefore described and inside or underneath the raised or
enlarged part B' of the outlet B which said raised or enlarged part B¹ is so formed
and shaped that a rod or other apparatus inserted through the aperture F can pass
directly into the drain or sewer C to assist which operation also we can make
when it is necessary from any cause so to do a slot in the top rim of the gully
opposite to this aperture. This aperture F which can be made of any shape
though preferably it is of a circular shape is formed with a suitable seat for a cap
which can be passed down the mouth of the gully and secured in its seat in any
convenient manner so as to tightly close the said aperture F as is desired. The
cap G can be made of any material and of such a shape as to fit the aperture F and
it inay be fitted and arranged as may be most suitable. In the drawing we have
shewn the cap G as preferably made of glazed earthenware and fitted into a plain
seat the joint being made air tight by cement or otherwise. We can also make
the cap of metal and in this case we should pass a ring with a female screw
through a slot in the top rim of the gully or in the raised enlarged part of the
outlet therefrom and let the lower part of this ring into the lower part of this
G

page_text: aperture in the side of the said gully and securely and tightly fix the said ring in
that position and a circular cap or plate with a male screw could then be screwed
into this ring by a key or otherwise anl the said aperture would be tightly closed
ns is desired.
We should prefer to use brass or otlier noncorrosive metal for this
cap and ring.
Figure 3 is a vertical longitudinal section of this our improved gully as fitted
with a container to receive the mud grease or other matter suspended in the
liquid that passes therethrough to the drain or sewer.
In this case we form a deep recess H in the bottom of the gully A which
recess H in horizontal sectional area is slightly smaller than the said gully A so
that a shoulder K. is created on two or more of the sides of the said gully A. A
container M preferably made of metal is fitted into the recess H being supported
therein by flanges on its upper edge which rest on the shoulders K and suitable
handles N are fitted to this container M by which the same can be lifted out and
the mud grease or other matter deposited by the liquid can therefrom be removed.
In this Figure we have shewn that side of the gully which forms the dip and in
which the aperture F is made not perpendicular or vertical but inclined backwards
so that the mouth of the gully may be enlarged without causing or necessitating a
corresponding enlargement of the whole gully which arrangement we find very
suitable in some cases and we also shew a different form of cap G with a corre-
sponding seat which form also is very applicable with this style of gully.
We have thus shewn and described two very suitable and convenient forins and
styles of this our improved gully for drains and sewers but we would have it clearly
understood as indeed is or ought to be sufficiently obvious that we do in no wise
limit ourselves to the precise shapes or forms of our apparatus and of the several
parts thereof and to the exact details of constructing and fitting the same as so
shewn and described for our improved gully and the several parts thereof may be
made of any shapes and forms and such methods may be used in constructing and
fitting the same as may be convenient or suitable or necessary in each particular
case.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
wo claim is
1. The improved gully for drains and sewers made and constructed and operating
substantially as and for the purposes hereinbefore described and declared and
shewn in the accompanying drawing.
2. The combination with the gully of the raised or enlarged part of the outlet
therefrom underneath which is the inspection aperture in the side of the said gully
substantially as hereinbefore described and set forth.
