PROVISIONAL SPECIFICATION.
Improvements in Sinks, Gulleys, and the like.
We, EBENEZER HARGREAVES, DAVID TAYLOR, and WILLIAM HENRY
WOMERSLEY, all of the Firm of Messrs. E. Hargreaves and Company, Water
Lane, Halifax in the County of York, Ironfounders, do hereby declare the nature
of this invention, to be as follows:-
The object of this invention is to construct street or other gulleys, sinks, and the
like, so as to trap, keep down and carry off all the stench or other noxious gases or
vapours.
We construct our improved gulley of any suitable shape, having a trap or box
cast upon same, such box projecting over the outlet from such gulley, upon the
top of this trap or box we form a suitable air valve consisting of a weighted
plug secured by a chain to the gulley side, such plug fitting within a suitable
hole in the said box or trap, and is for ventilating the said gulley trap when
required.
An indiarubber ring or washer placed upon the plug, or upon the top of the trap,
ensures the same being airtight.
Also we preferably fix the outlet near the top by which arrangement the gulley
is not liable to be choked or filled up, and it will also retain a considerable amount
of sediment before requiring to be cleaned out.
By this construction of gulley it is impossible for noxious gases and the like to
escape.

We, EBENEZER HARGREAVES, DAVID TAYLOR and WILLIAM HENRY
WOMERSLEY all of the Firm of Messrs. E. Hargreaves and Company, Water
Lane, Halifax in the County of York, Ironfounders, 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 :—
The object of this invention is to construct street or other gulleys, sinks and the

DESCRIPTION OF DRAWINGS.
Fig. 1. shows a sectional elevation of our improved gulley.
Fig. 2. shows plan of Fig. 1.
We construct our improved gulley A of metal or other suitable material of
any suitable shape, having cast upon same a suitable cover or trap B, such cover
projecting over the outlet C, which is preferably near the top.
In or near the top of this cover or trap, we form a suitable opening or valve D
having preferably a chilled seating E; within this opening or valve rests a suitable
flanged weighted plug F, around which and bedding against the said flange is an
indiarubber or other ring G, which when the plug is placed in the valve bears or
Pin1

page_text: rests upon the chilled seating, so accurately as to keep such trap perfectly airtight,
thus preventing all noxious gases from escaping from the drain.
This plug is secured to the side of the gulley by means of a suitable cord or
chain H, so that when desired the plug can be removed for purposes of ventilation,
and remain suspended within the gulley.
Also we leave sufficient space between the plug and the side of the opening as to
effectually prevent the same from corroding fast.
We preferably construct our gulleys, separately and independently of the frame
carrying the grates by means of which the latter may be raised to suit any level of
channel.
We also cut away or hollow out the corners J at the top of the gulley so that
no sediment can lodge upon same, but must necessarily fall into the bottom of the
gulley, and be carried away in the usual manner.
By our improved construction of gulley, the outlet is not liable to fill up or
choke, and being near the top allows more space for sediment, also when desired
the plug may be removed and all obstruction cleared, and by inserting a hose
pipe within the opening, the drains can be effectually flushed and cleaned.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The construction of street or other gulleys, sinks and the like, with cover or
trap B cast or fixed upon same, (and extending from towards the top of the
gulley at outlet C), such cover having suitable opening D, chilled seating E, loose
plug F, and washer G, for the purposes, substantially as shown and described.
