PROVISIONAL SPECIFICATION.
Improvements in or connected with Gullies.
FREDERICK HENRY BROOK, of 171 Queen Victoria Street London E.C.
Brick and Tile Merchant do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in or connected with gullies and other
appliances for which hinged flaps or grids are required and has reference more
particularly to the mode of connecting the grid to the top of drainage gullies or
the frames or dishes placed on top of such gullies, in order to permit of the grid
being easily placed in position, and of its being lifted or let down as upon
hinges.
In carrying out my invention I form the grid with lugs or projections at two
corners on one side thereof, and I form the top of the gully, or the grid-frame, or
dish-top, as the case may be, with recesses on two of the inner faces, in which the
aforesaid lugs engage when the grid is in position.
The recess on one inner face is cylindrical or conical, the recess on the opposite
inner face may be cylindrical or oval or of any other suitable form, and has
leading into it a groove or channel, (cut likewise in the inner face) which may be
of the same depth throughout, or may slope, and may be either horizontal or
inclined.
Those portions of the gully, dish-top, or frame in the neighbourhood of the
recesses may be of greater thickness than the other portions.
In order to fit the grid into the gully, dish-top, or frame, one of the lugs is
placed in the plain recess; and the other lug is slid into and along the groove in
the opposite inner face of the said top or frame until it engages in the recess at the
end of the groove; the grid will then fall into its place in the gully, top, or frame,
turning about upon the lugs as if hinged.
If it is desired to prevent the removal of the grid, the groove may then be filled
in with cement, or a suitable piece of metal or other material may be cemented or
fixed into it.
To facilitate the filling of the grid notwithstanding slight variations in the size
or shape of the gully, dish top, or frame commonly arising during manufacture, the
lower edge of the grid in immediate proximity to that lug which is first placed in
its recess, as described above, is bevelled or undercut, and the lug itself is bevelled
on its
upper surface.

COMPLETE SPECIFICATION.
Improvements in or connected with Gullies.
I, FREDERICK HENRY BROOK of 171 Queen Victoria Street, in the City of
London, Brick and Tile Merchant, 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 relates to improvements in or connected with gullies and other
appliances for which hinged flaps or grates are required & has reference more
particularly to the mode of connecting the grid to the top of drainage gullies or the
frames or dishes placed on top of such gullies in order to permit of the grid being

page_text: placed in position and of its being secured there while admitting of being
lifted up or let down as upon hinges.
I will now proceed to describe my invention with the aid of the accompanying
drawings.
Figure 1. is a view of the top of a drainage gully.
Figure 2. is a plan of the under side of a metal grate or grid.
Figure 3. is a plan of the top of a gully, similar to Fig. 1 shewing the upper
surface of a grid, similar to Fig. 2. placed in position.
Similar parts are similarly lettered throughout.
In carrying out my invention I form the grid Fig. 2, with lugs or projections C, C'
at two corners on one side thereof and I form the top of the gully, grid-frame, or
dish-top (Fig. 1) as the case may be, with recesses on two of the inner faces in
which the aforesaid lugs engage when the grid is in position.
The recess on one inner face is a conical hole, the recess A on the opposite inner
face may be cylindrical or oval or of any other suitable form, and has, leading into
it, a groove or channel B (cut likewise in the inner face) inclined as shewn in Fig. 1
and either of the same depth throughout or sloping.
The object of having the groove inclined is twofold, firstly to diminish the risk
of the top of the gully, between its upper surface & the groove, being broken
away, to which it would be very liable, if the groove were horizontal.
Secondly to diminish the risk of the cement or other material, with which the
groove is filled, being forced out or broken away in the course of use, as with this
form there is no direct blow on the end of the filling by the metal lug.
Those portions of the gully, dish-top or frame, in the neighbourhood of the
recesses may be of greater thickness than the other portions.
To facilitate the fitting of the grid, notwithstanding slight variations in the size
or shape of the gully, dish-top or frame, commonly arising during manufacture and
to diminish the difference between the sizes of the grid and gully top respectively,
which hitherto it is customary to allow to prevent jamming against one side while
gaping away on the other, the lower edge of the grid in immediate proximity to
that lug which is first placed in. its recess, is bevelled or under cut as shewn at D.
Fig. 2 and the lug itself is bevelled as shewn at C.
In fitting the grid into the gully, dish-top or frame, the lug C (Fig. 2) is placed
in the plain recess, and the other lug C' is then brought down (by canting the grid)
into the lower end of the inclined channel B and raised along the said channel until
it engages in the recess A at the top of the channel.
The grid will then fall into its place as shewn in Fig. 3 & can be turned up &
down as if hinged.
The groove B may then be filled up with cement or a suitable piece of metal
or other material may be cemented or fixed into it to prevent the removal of
the grid.
I am aware that it has been proposed to secure the metal grids to gullies, and
blocks for covering traps and gullies or bends, by providing a seating with a hole
on one side and a horizontal slot on the other employed for the reception of plain
round lugs or pivots formed on each side of the grates or grids, one of which is
first put into the hole and the other is then slid into or along the slot, up to the
end, but owing to the deviations from true rectangular form and other variations
of size & shape of the gully tops due to unequal shrinkage and working during
drying and burning of the earthenware, this method as at present carried out
cannot be regarded as satisfactory, I therefore make no general claim to such
construction, but
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In grids for fixing into gullies, undercutting or bevelling the underside of the
grid near the lug substantially as and for the nurnose herein before described

page_text: 2. In grids for fixing into gullies, tapering the lugs substantially as and for the
purpose hereinbefore described.
3. In gullies, grid-frames, or dish-tops to which grids are to be attached by lugs
or pivots, a conical recess on the one side and a slanting groove, leading into a
5 recess on the other side, substantially as and for the purpose hereinbefore
described.
4. Gullies, grid-frames or dish-tops and grids therefor, constructed substantially
as described with reference to the accompanying drawings.
