IMPROVEMENTS IN GULLIES
Year: 1882

page_text: PROVISIONAL SPECIFICATION left by the said Herbert Kelly at the Office
of the Commissioners of Patents on the 20th May 1882.
HERBERT KELLY of Fitzjohns Avenue Parish of St John, Hampstead in the
County of Middlesex "IMPROVEMENTS IN GULLIES
"
This gully is preferably formed in shape of a rectangular box the bottom for
about half its length being slanted up.
In the lowest part of the bottom is an opening provided with a grid which fits
over an ordinary P or S trap, and through the sides are introduced waste pipes as
needed, generally about three in number. The top of the gully is covered with
two plates one in form of a grid and the other solid but having an opening for a
rain water pipe. The top plates are removable and interchangeable so that the
rain water pipe may enter directly over the drain (or at that end of the box) if
desired. By the former arrangement the rain water flows down the slanting
portion and tends to wash the gully and grid, and as the top plates can be removed
the interior is readily accessible for cleaning et cetera.
These gullies can be made of the materials usually employed for such articles,
say stone ware cast iron and the like.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Herbert Kelly in the Great Seal Patent Office on the 20th November

In the lowest part of the bottom is an opening provided with a grid which fits
over an ordinary P or S trap and through the sides are introduced waste pipes as
needed generally about three in number. The top of the gully is covered with
two plates one in form of a grid and the other solid but having an opening for a
rain water pipe. The top plates are removable and interchangable. By this
arrangement the rain water flows down the slanting portion and tends to wash the
gully, and as the top plates and grid can be removed the interior of both gully
and trap are readily accessible for cleaning &c.
These gullies can be made of the materials usually employed for such articles,
say stone ware, cast iron and the like.
The accompanying drawing is a sectional perspective view of the gully as set in
the ground A is the interior B the flat portion of the bottom and C the inclined
portion upon which the rain water pipe D discharges when arranged as in the
drawing, E is the grid which forms the entrance from the ground level for surface
drainage so that this may be used as a yard gully, F is the solid cover through
which the rain water passes; E and F are removable, and interchangeable. The
rain water pipe D may be round, square, or of other section. H is an ordinary P
or S trap over which the gully fits, this is a better plan than forming both gully
and trap in one piece, because in the former case the trap cau be turned in any
direction to suit the angle of the drain and make a tight joint. The upper edges I
of the walls of the gully are turned over or bevelled outwards so as to facilitate
the entrance of the water from the ground. K is a grid over the outlet G and
serves to keep leaves, sticks &c brought by the rain water pipe or rubbish from
sinks from entering the trap. By removing the grids E and K the gully and trap
can readily be cleaned at any time. L and M. are waste pipes which discharge
into the gully as shown; the number of these can be varied but usually there are
about three besides the rain water pipe N is a bridge across the gully—or lugs at
the sides would do to support the covers E and F
By this simple arrangement of gully the requirements of most of the Local
Boards and other authorities are carried into effect and the Rain water pipe, sink
and other wastes are disconnected from the drain and at the same time are
ventilated, whilst splashing is prevented.
Having now described my invention and the method of performing the same I
wish it to be understood that what I claim and desire to protect under the
berein before in part recited Letters Patent is ;
First The herein described improved gully in which the rain water and waste
pipes discharge into one disconnecting and ventilating chamber which
also prevents splashing substantially as set forth and shown.
Second-The combination of the inclined bottom C and removable grid or
cover E whereby the rubbish discharged by the rain water or waste pipe
upon said.inclined bottom is more freely conveyed by the water under
the removable cover whence it can be easily removed and the less
accessible portion of the gully is rendered practically self cleansing
substantially as set forth and shown.
In witness whereof I the said Herbert Kelly have hereunto set my hand
and seal this
day of November in the year of Our Lord one
