unsealed, so that the sewer gas can pass through the gulley and escape into the air,
causing a well-authenticated annoyance, and one which is obviated only with
comparative difficulty and expense.
One plan is to send a water-cart round and fill the wells with water, but owing
to the large extent by the evaporating surface, this has to be done frequently,
which, besides using a large quantity of water, is an expensive operation.
According to the present invention, the area of evaporation is reduced to the
minimum, and the sealing of the drain is thus ensured for the longest possible
period, while the quantity of water being comparatively small, the sealing, in case
of necessity, is a simple and inexpensive matter.
To effect this object, we adapt to the well a syphon trap of any convenient
depth, and above this trap, and in line with the drain, is a passage which we close
with a suitable plug.
As the syphon trap will open into the upper part of the well, we may almost
double the depth of an ordinary well without the risk of stopping up the outlet.
In the accompanying drawing, we have shown in sectional elevation the most
simple form of producing our anti-evaporation street gulley.
A is the well, which may be of any depth (if desired, of less depth than the
ordinary well), but of whatever depth, the whole of the well is available to collect
mud and other solid matters which may be carried down the gulley by the rain,
because the outlet to the drain is near the top.
To this outlet we adapt a syphon trap B, the trap being preferably formed by
a vertical partition B', which dips down the required distance into the syphon
well.
In this partition we provide an opening in line with the outlet of the trap, and
with the drain that connects the gulley with the sewer, and this opening we
normally close with a plug C.
In front of the well outlet, we find it advantageous to place a wire screen D, to
prevent the passage of leaves, sticks, and twigs into the trap.
In the arrangement shown, the well of the trap is readily accessible from the
ground level, so that any sediment can be readily removed, either by a suitable
tool, or by simple flushing.
On removing the plug C, a suitable tool may be pushed down the drain, to clear
away any obstruction therein; in other words, the drain can be readily inspected
when necessary.
It will be obvious that we do not intend to confine ourselves to the exact form
of gulley shown, which is only intended, by way of example, to illustrate the
essential points of the invention, namely, to prevent more or less the evaporation
of the seal water; accessibility of both trap and drain, to provide for ready
inspection of the drain; and to provide increased accominodation for the reception
of solid matters, without interfering with the proper working of the gulley.
Having now particularly described and ascertained the nature of the said inven
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. A street gulley consisting of a well having, at its upper part, an opening or
"openings to which is or are adapted a syphon trap, and an inspection passage or
opening provided with a removable plug, as and for the purpose set forth.
2. A street gulley in which the evaporation of the seal water is more or less
prevented, inspection is provided for, and the parts are readily accessible for
cleansing, substantially as herein shown and described.
3. The street gulley as herein shown and described.

PROVISIONAL SPECIFICATION.
Improvements relating to Street Gullies.
We GEORGE MARLOW REED of 4 Byron Villas, Bound's Green in the County
of Middlesex, Agent, and WILLIAM HENRY KNIGHT of Gisburn Road, Hornsey,
in the County of Middlesex, Sanitary Engineer, do hereby declare the nature of
this invention to be as follows:-
The object of this invention is to provide for the more efficient trapping of street
gullies than heretofore, at the same time providing ready means for cleaning the
drain when necessary.
Street gullies are usually formed with a deep well, in which the mud and dirt
collect, while the water runs off, through a suitable pipe or outlet, generally so
arranged that a quantity of water shall remain in the well to form a seal.
This water, however, evaporates, with the consequent result that the outlet
becomes unsealed, and the sewer gas can thus pass through the gully and escape
into the air.
According to the present invention, the area of evaporation is reduced to the
minimum, and the sealing of the drain is thus ensured for the longest possible
period.
To effect this object, we adapt to the well a syphon trap of any convenient
depth, and above this trap, and in line with the drain, we form a passage to the
upper part of the well, which passage we close with a suitable plug.
As the syphon trap will open into the upper part of the well, we may almost
double the depth of an ordinary well, without the risk of stopping up the outlet.
Dated this 1st day of February 1896.

We GEORGE MARLOW REED, of 4 Byron Villas, Bound's Green in the County
of Middlesex, Agent, and WILLIAM HENRY KNIGHT, of Gisburn Road, Hornsey
in the County of Middlesex, Sanitary 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 :-
The object of this invention is to provide for the trapping of street gullies in a
more efficient manner than heretofore, at the same time providing for the ready
removal of mud or sediment from the trap, and for cleaning the drain when
necessary.
Street gullies are usually formed with a deep well, in which the mud and dirt
collect, while the water runs off through a suitable pipe or outlet, generally
opening into the well about balf way down, and so arranged that a quantity of
water shall remain in the well to form a seal.
This water, however, being open to the action of the atmosphere and of the sun's
rays, quickly evaporates, with the consequent result, that the outlet becomes
