Holes and other Places where Gratings are Required.
We, EDGAR PURNELL HOOLEY of Barming, Maidstone, Surveyor, and JESSE
ELLIS of Invicta House, Buckland Hill, Maidstone, Engineer, do hereby declare the
nature of this invention to be as follows:-
Ordinarily the gratings used for covering over the gully holes at the sides of streets
are made with parallel bars set either in a line with the street or at right angles to it.
In either position there is a tendency for the grating to become choked. We form
the gratings of parallel bars set diagonally or at an angle to the rectangular framing
within which the grating is carried so that as a stream of water flowing along the side
of the roadway comes to the grating any sticks or refuse carried along with the
water will as they arrive at the grating be deflected sidewise by the bars and so the
greater if not all of the grating will always be left clear for water to pass down
through it.
The outer frame within which the grating is carried we make rectangular.
The sides of the grating we also make rectangular but of smaller size and we
form it with projections extending from its four corners to fit to the four corners of
the outer frame.
The grating we also make capable of being turned up on pivots at one side-The
top edge of the diagonal bars of the grating we make V shape in cross section
instead of flat as is generally the case with the bars of other gratings-we also make
the top of the bars to rise to a higher level at the centre of the grating than at its
sides.
In order to be able to fix the outer frame firmly into the brickwork at the top of a
gully hole we form the frame with each of its sides prolonged beyond the points where
the sides meet so as to form outward extensions which may be firmly embedded into
the brickwork

page_text: In some cases in place of making the grating in one piece we make it in two and
the hinge joint upon which one of them turns we place at one end of the outer frame
and the other across the centre of the frame-the diagonal bars of one frame may also
be inclined in the opposite direction to the bars of the other frame.

Improvements in Gratings Used for Covering Over Street Gully
Holes and other Places where Gratings are Required.
We, EDGAR PURNELL HOOLEY, of Barming, Maidstone, Surveyor, and JESSE
ELLIS, of Invicta House, Buckland Hill, Maidstone, 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 :-
Ordinarily the gratings used for covering over the gulley holes at the sides of
streets are made with parallel bars set either in a line with the street or at right
angles to it.
In either position there is a tendency for the grating to become choked.
We form the gratings of parallel bars set diagonally or at an angle to the rectangular
framing within which the grating is carried so that as a stream of water flowing along
the side of the roadway comes to the grating any sticks or refuse carried along with
the water will as they arrive at the grating be deflected sidewise by the bars and
so the greater part if not all of the grating will always be left clear for water to pass
down through it.
The outer frame within which the grating is carried we make rectangular.
The sides of the grating we also make rectangular but of smaller size and we form
it with projections extending from its four corners to fit to the four corners of the
outer frame.
The grating we also in some cases make capable of being turned up on pivots at
one side.
In order to be able to fix the outer frame firmly into the brickwork at the top of a
gully hole we form the frame with each of its sides prolonged beyond the points
where the sides meet so as to form outward extensions which may be firmly embedded
into the brickwork.
In some cases-in-place-of-making the grating in one piece we make it in two and
the hinge joint upon which one of them turns we place at one end of the outer frame

page_text: and the other across the centre of the frame the diagonal bars of one frame may also
be inclined in the opposite direction to the bars of the other frame.
Figure 1 of the drawings hereunto annexed is a plan view of a gully grating formed
as above described.
Figure 2 is a section on the line A B Figure 1 and
Figure 3 a section on the line C D.
The drawings shew the grating formed to drop into its place in the outer frame and
with this frame made with inwardly projecting flange pieces at the corners for the
corners of the grating to rest on but as above stated the grating may if desired be
made so that it can be turned up on pivots. The openings through the grating are as
shown made to taper-their widest ends being at the bottom. This allows anything
blocking such as a stone-to fall through to the catchpit underneath.
The construction of the outer frame is shown in Figures 1 and 2. It is formed
with horizontal flanges projecting outwards from the bottom of its vertical sides and
also with these sides prolonged beyond the points where the sides meet so that the
grating may be embedded firmly. These prolongations of the vertical sides do not
rise to quite the same height as the sides themselves.
Gratings formed as above described can be used in other cases wherever a stream
of water having solid matters floating in it has to be passed away downwards through
a grating.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The construction of gratings used for covering over street gully holes and other
such like places substantially in the manner herein before described.
2. The construction of gratings used for covering street gully holes and such like
places with the parallel bars of the grating inclined to the sides of the outer rectangular
frame.
3. The construction of the outer frame of a street gully hole substantially in the
manner hereinbefore described and illustrated in the drawings annexed.
