page_text: LETTERS PATENT to Abraham Wood, of Menston in Wharfedale, in the County

PROVISIONAL SPECIFICATION left by the said Abraham Wood at the Office
of the Commissioners of Patents on the 23rd August 1877.
ABRAHAM WOOD, of Menston in Wharfedale, in the County of York. ." IMPROVE
MENTS IN STREET GULLIES."
'
The object of my Invention is to construct a perfectly trapped gulley, and a
simple arrangement in connection therewith for conveying therefrom the obnoxious
gases.
The gulley consists of a box of metal or other suitable material, and is provided
with trapped compartments so arranged, that on the box being filled with water to
a suitable extent, the communication between them is closed.
The overflow pipe to the sewer is attached to one of these compartments; also a
pipe in connection with the fall pipe or pipes of buildings for the purpose of
passing off the gas above the buildings; also for conveying the rain water to the
sewer.
Instead of being connected with fall or other pipes the gases may be conveyed to
an adjacent mill or other chimney or flue.
The other compartment is used for the admission of top water, and being tapped
as aforesaid, all obnoxious gases are prevented from rising into the street.

ABRAHAM WOOD, of Menston in Wharfedale, in the County of York. " IMPROVE-
MENTS IN STREET GULLIES."
The object of my Invention is to construct a perfectly trapped gulley and a
simple arrangement in connection therewith for conveying therefrom the obnoxious
gases.
The gulley consists of a box of metal or other suitable material, and is provided
with trapped compartments so arranged, that on the box being filled with water to
a suitable extent, the communication between them is closed.
The overflow pipe to the sewer is attached to one of these compartments; also a
pipe in connection with the fall pipe or pipes of buildings for the purpose of
passing off the gas above the buildings; also for conveying the rain water to the
sewer.
Instead of being connected with fall or other pipes, the gases may be conveyed
to an adjacent mill or other chimney or flue.
The other compartment is used for the admission of top water, and being trapped
as aforesaid, all obnoxious gases are prevented from rising into the street.
Figure 1 of the accompanying Drawings is a plan of a trapped gulley made and
fitted according to this Invention; Figure 2 is a vertical section through line A, A;
and Figure 3, a vertical section at right angles thereto, that is, on line B, B.
The gully is in the form of a box, and is by a hanging partition a divided into
two compartments b and c, which, when filled with water to a considerable extent,
as here shewn, are separated from one another. The compartment b is open at top
and receives the rain or other water from the street destined to be run off into the
sewer; the other compartment c is closed at the top by means of a well-fitting
lid d.
As shewn at Figure 2, the gulley is applied to a street or road, and is covered by
an ordinary grating e; on removing the latter and the lid d, the gulley may be
cleaned out when required; f is the overflow pipe to the sewer; 9 is a pipe in
connection with the fall pipe or rain water pipe from an adjoining building, or it
may be in connection with any ventilating shaft or flue, or mill or other chimney,
the noxious gases are thereby carried off effectually.
And having thus described and ascertained the nature of this Invention, I declare
that I do not claim making trapped gullies, but I do claim the construction of
gullies having one compartment open or suitable for the influx of the top water,
but trapped against the other closed compartiment, which latter is connected with
the sewer and with a ventilating pipe as set forth.
In witness whereof, I, the said Abraham Wood, have hereunto set my hand
and seal, this Twenty-first day of February, in the year of our Lord One
thousand eight hundred and seventy-eight.
Witness to the signature of
Abraham Wood,
