Improvements in Gulley Traps for Drains.
We, JAMES ALSOP, of Whatstandwell, Derbyshire, of the Firm of Alsop & Eley
Ltd., Sanitary Pipe Works, Whatstandwell, Derbyshire, and JAMES BRIGHTMORE,
Tideswell, Derbyshire, Sculptor and Builder, do hereby declare the nature of this
invention to be as follows:-
An ordinary earthenware gulley trap, with box attachment, all moulded in one
piece which will be constructed in 3 different forms for the following purposes.
First, for domestic use. 2nd, for hospitals, barracks, & asylums, & 3rd for hot
climates.
For domestic use the box attachment will be of simple form, in front of gulley,
over the trap & will be charged with a special disinfectant which gives out
The internal sides of
oxygen when sewage matter comes in contact with it.
gulley will be grooved to carry sewage into the disinfecting box. This box is
so constructed with perforated front to allow the sewage to have contact with the
disinfectant. This disinfectant acts as a deodrant when the gulley is not in use.
For hospitals, barracks, &c.-The same box attachment will be used in a
different form. The box being so constructed so as to be on each side & on front
of the gulley and will be filled with the disinfectant, containing à large percent-
age of manganate of potash.
The gulley in this case will have a grooved shoot formed internally in same, to
carry the sewage or liquid into the disinfecting box. The box has also on all
sides perforations to allow sewage to percolate through same.
For hot climates.-Gulley in this instance will be made of glazed earthenware
the inside will be oval shaped, and the box attachment as before, but of a dif-
ferent form being placed in front of gulley, perforated with small holes: the gulley
will also have internally an oval shaped, grooved, shoot in same to carry water
out of disinfecting box.
Each of them are most simple in construction, being made of vitrious sanitary
earthenware, & the object of charging them with special disinfecting block is to
destroy all bacteria & microbes before entering the sewers, either lateral or main
sewers, and the action of the disinfectant, deodorises noxious vapours, the oxygen
given off being ample to effect this. The gulley traps can be used in the ordinary
way, but in cases of zymotic diseases, & other contagious diseases, the use of the
disinfecting slots will be found invaluable, as the micro organisms of sewage, are
for the most part bacilli.
In all water conservancy it will be quite practicable and of great service, where
there is only an intermittent flow of sewage, or in which sewage stagnates, and
becomes highly putrifactive.
It will be easily seen, that if universally used, all sewage matter will arrive at
the precipitation tanks deodorised.
These gullies will also be constructed of metal as well as the vitrious clay.

We, JAMES ALSOP, of Whatstandwell, Derbyshire, of the Firm of Alsop & Eley
Limited, Sanitary Pipe Works, Whatstandwell, Derbyshire, and JAMES BRIGHT-
MORE, of Tideswell, Derbyshire, Sculptor and Builder, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be parti-
cularly described and ascertained in and by the following statement:-
-
The object of our invention is to produce a disinfecting and deodorising gulley
trap which is simple in construction and efficient in action, all bacteria and
microbes being destroyed before entering the sewers, whilst the oxygen given off
from the disinfectant deodorises all noxious vapours.
The use of our improved gulley trap is practicable in all water conservancy,
and is of special service where there is only an intermittent flow of sewage or
where the sewage stagnates and becomes highly putrefactive. If generally
adopted the sewage matter on arrival at the precipitating tanks will require but
little treatment.
Referring to the annexed three sheets of explanatory drawings;
Sheet 1 illustrates a simple form of disinfecting gulley trap according to our
invention intended chiefly for ordinary domestic and general purposes.
Sheet 2 is a form suitable for hospitals, asylums, barracks and like institutions,
and,
Sheet 3 a form applicable for use in hot or tropical climates.
Like letters of reference denote similar parts throughout and corresponding
views are shown in each respective sheet, Figure 1 being a general external view,
Figure 2 a plan, Figures 3 and 4 vertical sections and Figure 5 an end elevation.
According to our invention the sealed gulley trap A which may be of earthen-
ware or metal, is moulded or otherwise formed or provided with an auxiliary box
attachment, chamber or receptacle B, arranged as shown in front and above the
gulley trap, for containing a disinfectant composed of a large percentage of
manganate of potash or the like capable of giving off oxygen when the sewage
matter comes in contact therewith, the disinfecting media being closely packed in
the receptacle B. The front or sides of the latter are formed with vertical slots,
openings or perforations 6 to allow the disinfectant to be thoroughly exposed to
and mingle with the water entering through the grid of the trap A, and, in order
to ensure the more efficient admixture of the disinfectant with the water passing
through the trap I form the interior with grooves or ribs a, Figure 3 Sheet 1, to
carry the sewage into the disinfecting box B, or with inclined shaped deflecting
or dash plates a¹, Figure 3 Sheets 2 and 3 whereby the water is at once diverted
into the disinfecting box B and disinfected before it passes through the trap. In
like maner any foul air or gas arising from the water in the trap mingles with
and is neutralised by the disinfectant in the box B which is provided with a
suitable lid or cover to allow of the ready removal and replacement of the disin-
fectant.
In the form of gulley trap shown in Sheet 2 intended for use more particularly
in hospitals, barracks and the like, the disinfecting box or chamber B is arranged
in front and also at the sides of the gulley, and, in lieu of the grooves or ribs a
is formed with a grooved shoot or plate a¹, as shown in Figure 3, for deflecting
the water or sewage into the disinfecting box B the slots or perforations b in the
sides of which allow the water to percolate therethrough.
In the form shown in Sheet 3 which is intended for use more particularly in

page_text: hot climates where the specific gravitation is not so great, the gulley is made of
glazed earthenware and is oval in shape, the disinfecting box or chamber B being
placed in front of the gulley, and, in this instance may be perforated with small
holes b, the gulley being formed internally with an oval shaped grooved shoot a¹
Figure 3 to carry the water into the disinfecting box.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
-
First: The general construction and arrangement of a gulley trap A moulded
or formed in conjunction with a disinfecting box, boxes or receptacles B arranged
as shown at the front or sides thereof having slots, openings, or perforations b
communicating there between and means comprising grooves or ribs a or inclined
or shaped dash plates a¹ or equivalents for deflecting the incoming water or sewage
and outgoing air or gases into and causing same to mingle with and be dis-
infected or deodorised by the disinfectant contained in such box or receptacles B
substantially in the manner and for the purposes specified and as illustrated in
the accompanying drawings.
Second The combination with a gulley trap A of one or more disinfecting
boxes or receptacles B arranged as shown and formed with slots or openings b and
internal grooves or ribs a or dash plates or shoots a' for causing the admixture of
the incoming water with the disinfectant in the said chamber or chambers B sub-
stantially as herein set forth and shown and for the purposes specified.
Third-The improvements in gulley traps for drains all as herein set forth
and shown and for the purposes specified.
