Improvements in Means or Apparatus to be employed in connection
with Sewer Gulleys or the like for Disinfecting Purposes.
We MARMADUKE MILLER and JOHN MILLER both of the Firm of J. Miller
and Company of 124 Commercial Street Whitechapel in the County of London,
Wholesale Ironmongers and Sanitary Engineers do hereby declare the nature of
this invention to be as follows:-
The invention relates to improvements in means or apparatus to be employed in
connection with sewer gulleys or the like for disinfecting purposes.
It is well known that however well a sewer or drain may be trapped, a certain
proportion of sewer gas leaks through and escapes by the grating, greatly
endangering the public health.
With a view to obviate or modify this danger, it is a common practice to sprinkle
disinfecting powder over and about the gulley or ventilator grating, and to pour
disinfecting material into the gulley but this has the disadvantage that when the
drain is flushed by a fall of rain or otherwise, the disinfectant is immediately
washed away.
Now the objects of the present invention are to provide a device alike applicable
to sewer gulleys or the like and ventilators whereby the disinfecting material will
be stored beneath the grating and the gases issuing from the galley will be
compelled to pass over such material previous to passing away to the outer air, so
that the gradually evaporating disinfectant will commingle with the issuing gases,
and thereby render the same innocuous; to protect the disinfecting material from
being washed away by a downward flush; to enable the device to be readily
replenished when desired; and to so construct the same that the device may be
readily applied to existing gulleys ventilators or the like.
In applying the invention to a street gulley rectangular in form, a rectangular
box is employed which tightly fits into the mouth of the gulley and is provided
with flanges which engage lugs upon which the grating rests and thus hold the box
suspended in correct position.
Within this box is arranged a rectangular trough, dish, or reservoir which is
intended to contain the disinfecting material which should be of a volatile
character.
The trough, dish or reservoir is enclosed within a chamber formed with an
opening at the top and a larger opening at the bottom, and at the upper part
formed with sides inclined to overhang the trough whilst above the opening at the
top of the chamber is arranged a bell or cover adapted to protect the trough, dish,
or reservoir aud its contents from descending water or other matter, and this cover
is provided with an aperture closed by a stopper through which the disinfecting
material may be supplied to the trough dish or reservoir without the necessity for
removing the device from the gulley.
Meeting the bottom of the chamber are provided inclined deflecting or stop plates
which prevent the rising gases passing around the chamber and compel the same to
pass therethrough and over the trough of disinfecting material, whence they pass
through the opening in the top of the chamber and through the passage between
the same and the bell or cover and after which they are free to pass away by the
grating, the circuitous passage of the gases causing them to be brought into intimate
contact with the vapourised disinfecting material.
At the lower part of the disinfecting chamber the sides are hinged to the body

page_text: of the chamber and the deflecting plates are arranged in such manner that the
hinged sides which open inwardly normally rest against the same and close the
passage around the exterior of the disinfecting chamber whilst in the event of a
heavy flush of water passing into the gulley grating, the same will be conducted by
the bell or cover around the exterior of. the disinfecting chamber when it will be
guided or directed by the inclined deflecting plates against the hinged sides of the
disinfecting chamber which will be opened by the pressure and allow the water to
pass away, after which they will again automatically close.
The device may be made in malleable cast iron or in sheet iron or in earthenware
or other suitable material, and it may be formed according to the shape of the
gulley in which it is to be placed.
When the invention is to be employed in connection with ventilator_gratings
which are commonly circular in form the box is made cylindrical and with a
circular top which rests at its periphery upon a rim or flange of the ventilator
fitting below the grating whilst the trough is suspended by a tubular stem provided
with a feed opening near to its lower end and at its upper end furnished with an
opening closed by a stopper through which the disinfecting material may be fed
whence it will flow through the lower opening into the trough.
In this case as there is little or no fall of water, the hinged sides to the
disinfecting chamber are dispensed with, and in lieu of the co-acting deflecting
plates, the top of the disinfecting chamber is extended to meet the box whilst the
bell or cover is formed with a rising rim constituting a dirt box to collect any
foreign matter falling through the ventilator grating.
Although the invention is described in connection with gulleys or drains and
ventilators, it will be understood that it can be usefully employed in other situations
provided that proper access is given to the upper part of the tubular stem for the
purpose herembefore expressed.
Or in cases where it is desired to employ blocks of disinfecting material, the
trough or reservoir may be replaced by any other suitable form of holder whilst
still retaining the other parts of the device.
By the means herein before described we are enabled to employ the disinfecting
material in connection with sewer gulleys, ventilators or the like in a more effective
and economical manner than heretofore, inasmuch as the disinfectant will
continuously give off its gas or vapour until it is exhausted, the sewer gases or
vapours will by the peculiar construction of the device be compelled to pass over
the trough and through a circuitous passage before they pass away to the outer air,
thereby being brought into intimate contact with the evaporating disinfecting
material whilst at the same time there will be little or no waste as such material is
completely protected from descending water or the like.

And in order that the said invention may be more clearly understood and readily
carried into effect we will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical transverse section representing a sewer gulley or grating
having the present invention applied thereto.
Figure 2 is a plan thereof.
Figure 3 is a similar view to Figure 1 but taken at right angles thereto.
Figure 4 is a similar view to Figure 1 but representing a modified form of
device.
Figure 5 is a vertical transverse section representing the application of the present
invection to a sewer ventilator or manhole.
Figure 6 is a plan thereof.
Figure 7 is a similar view to Figure 6 but showing the grating removed.
Figure 8 is a plan of part thereof.
In the several figures like parts are indicated by similar letters of reference.
Referring to Figures 1, 2, and 3 a represents a sewer gulley of ordinary con-
struction, a represents the gulley grating, and represents a rectangular box
which tightly fits into the mouth of the gulley a, and is provided upon two sides
with lateral flanges which rest upon or engage lugs or flanges a² formed with
the gulley a and upon which the grating a rests and the box is thus held
suspended in correct position, whilst at the same time the way through the gulley a
is entirely occupied by the box b.
Within the box bis arranged a rectangular trough, dish, or reservoir
intended to contain disinfecting material and which latter should be of a volatile
character.
The trough, dish, or reservoir is enclosed within a chamber formed with an
opening 6* at the top and with a laiger opening at the bottom and the trough,
dish, or reservoir 63 is by brackets 62 supported in the chamber at a suitable distance
from the walls thereof."
The walls of the chamber at the upper part thereof are formed inclined to
overhang the trough whilst above the opening 64 at the top of the chamber is
fixed a bell or cover which is supported in the required position by angle
brackets b* fixed therewith and with the box b.
The office of the bell or cover 6 is to protect the trough, dish, or reservoir b
and its contents from descending water or other matter and to form a circuitous
passage for the gases issuing from the disinfecting chamber and the cover be is pro
vided with a central aperture closed by a stopper 67 and through which th
disinfecting material may be supplied to the trough, dish, or reservoir 6 by
the aid of a funnel or the like without the necessity for removing the device from
the gulley a.
·
Meeting the bottom of the chamber 63 are provided inclined deflecting or sto
plates which together with the box b prevent the gases rising in the sewer from
passing between the walls of the box b and the chamber 6 and thus compelling the

page_text: Fame to pass through the chamber and over the trough of disinfecting material
whence they pass through the opening at the top of the chamber and through
the passage between the same and the bell or cover 6 after which they are free to
pass away by the grating a¹; the circuitous passage traversed by the issuing gases
and the concentration thereof at the upper part of the disinfecting chamber b
causing the gases to be brought into intimate contact with the vapourized
disinfecting material.
The sides forming the walls of the lower part of the disinfecting chamber b³
are hinged to the body of the chamber and the deflecting plates are arranged in
such manner that the hinged sides 3* which open inwardly normally rest against
the same and close the passage which otherwise would exist around the exterior of
the disinfecting chamber whilst in the event of a heavy flush of water passing
into the gulley grating a' the same will be conducted by the bell or cover be around
the exterior of the disinfecting chamber 6 when it will be guided or directed by
the inclined deflecting plates 68 against the hinged sides 63* of the disinfecting
chamber which will be opened by the pressure and allow the water to pass away
after which they will again automatically close by gravity.
The device may be made wholly or partly of malleable cast iron or in sheet iron
or of earthenware or other suitable material and it may be formed according to the
peculiar shape of the gulley in which it is to be placed.
In the example given at Figure 4 a modified form of device is shown suitable to be
employed in connection with either solid or liquid disinfecting material.
In this case the trough, dish, or reservoir 63, instead of being fixed with the
walls of the disinfecting chamber is loosely supported upon horizontal rods or
bars and is furnished with distance pieces which keep it central and in order to
charge the trough, dish, or reservoir 6 the bell or cover 66 is loosely mounted upon
brackets and provided with feet which rest upon the disinfecting chamber so
that it may be readily lifted off and the trough, dish, or reservoir 6 is provided
with a handle 62** by which it may be lifted and the upper inclined sides of the
chamber bare hinged at 63** to the body of the chamber 63 in order that they may
be turned back so that upon opening the grating a lifting off the bell or cover b
and turning back the overhanging sides into the position indicated by the dotted
lines in Figure 4, the trough, dish, or reservoir may be readily removed and
replenished with disinfecting material either solid or liquid as the case may be.
It will be understood that when employing solid disinfecting material in block or
other form any other suitable kind of holder may be substituted for the trough or
dish whilst still retaining the other parts of the device.
In the example given at Figures 5 to 8 the device is shown applied to a sewer
ventilator grating or manhole cover circular in form.
In this case the box 6 is formed cylindrical and at its upper part with a circular
flange which rests upon a corresponding rim or flange a' of the ventilator fitting a
below the grating a whilst the trough, dish, or reservoir 6 is supported by a tubular
stem provided with a feed opening 6 near to its lower end, and at its upper end
closed by a stopper 6' through which the disinfecting material may be fed whence
it will flow through the lower opening 6°* into the trough b³.
In this case as there is likely to be little or no fall of water through the grating a¹
the hinged sides 63* of the disinfecting chamber and the co-acting deflecting
plates are dispensed with and in lieu of the latter the top of the disinfecting
chamber is extended to meet the walls of the cylindrical box b whilst the bell or
cover is formed with a rising rim 6*** constituting a dirt box to collect any
foreign matter falling through the ventilator grating a
The dirt box 6 is formed with a central aperture and fits upon the upper end of
the feed pipe where it is supported by a flange or collar 6*** and securely held
by a bar which is apertured and interiorly threaded to screw upon a corresponding
thread formed upon the upper end of the feed tube 6 whilst the bar 60 at its ends
takes a bearing upon the Hange or rim 6' of the box b.
When it is desired to cleanse the dirt box 6 the grating a¹ and bar 610 may be

page_text: removed and the dirt box 6 may be lifted out leaving the tubular stem 6° fixed
with the box or the entire device may be removed bodily by grasping the
bar 10.
In charging the trough b³ with disinfecting material it is only necessary to lift
the grating a and remove the stopper 67, when the disinfecting material may be
fed into the trough, dish, or reservoir through the feed tube 6.
Although the invention is described in connection with gulleys or drains and
ventilators, it will be understood that it can be usefully employed in other situations
provided that proper access is given to the upper part of the tubular stem 6° or to
the trough, dish, or reservoir 63 for the purpose hereinbefore expressed.'
By the means herein before described we are enabled to employ the disinfecting
material in connection with sewer gulleys, ventilators or the like, in a more effective
and economical manner than heretofore inasmuch as the disinfectant will continuously
give off its gas or vapour in large volume until it is exhausted and the whole of
the sewer gases or vapours will, by the peculiar construction of the device be
compelled to pass over the trough or reservoir and through a circuitous passage
before they pass away to the outer air, whereby they will be brought into intimate
contact and caused to commingle with the evaporating disinfecting material whilst
at the same time there will be little or no waste of such material, as the same is
completely protected from descending water or the like.
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 disinfecting apparatus for sewer gulleys, ventilators, or the like comprising
a box adapted to closely fit the gulley or the like so as to compel all the sewer gases
to pass therethrough, a trough, dish, or reservoir for containing the disinfecting
material suspended within the box, a cover or chamber enclosing or partially
enclosing the trough, dish, or reservoir and at its lower end connected with the
walls of the box so as to compel the whole of the sewer gases to pass by and over
the trough, an escape opening at the top of the cover or disinfecting chamber and
a bell or cover for protecting such opening against descending matter substantially
as herein shown and described.
2. A disinfecting apparatus for sewer gulleys or the like comprising a disinfecting
chamber at its lower part extending to the walls of the gulley or the like and at
its upper part tapered or contracted and provided with a suitable opening a bell or
cover mounted above the opening so as to leave a passage between the parts,
a trough, dish, or reservoir located within the disinfecting chamber and means for
suspending the entire device in position substantially as herein shown and
described.
3. A disinfecting apparatus for sewer gulleys or the like comprising a box
adapted to closely fit the gulley or the like so as to compel all the sewer gases to
pass therethrough a disinfecting chamber mounted within the box and at its upper
part tapered or contracted and provided with an opening protected against
descending matter by a bell or cover and at its lower part formed with sides hinged
to the body of the disinfecting chamber downwardly inclined deflecting or stop
plates carried by the box and against which the hinged sides of the disinfecting
chamber rest by gravity, a trough, dish, or reservoir mounted within the disinfecting
chamber clear of the sides thereof and means for fixing the entire device in position
substantially as herein shown and described.
