Improvements in Means or Apparatus to be employed in connection
with Sewer Gulleys or the like for Disinfecting Purposes.
I MARMADUKE MILLER of the Firm of J. Miller and Company of 124 Com-
mercial Street Whitechapel in the County of London Wholesale Ironmonger
and Sanitary Engineer do hereby declare the nature of this invention to be as
follows:-
My 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 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 object of the present invention is to provide a device whereby the
disinfecting material will be stored beneath the grating and the gases issuing from
the gulley will be conducted 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 provide means whereby the device may
be readily applied to existing gulleys or the like.
In carrying the invention into effect an annular trough, dish, or reservoir is
employed to contain the disinfecting material and formed or fixed thereon and
centrally thereof is provided a tubular stem or body which rises a suitable distance
above the reservoir or trough.
The lower part of this tubular body at its junction with the annular trough or
reservoir is downwardly flared in order to receive and collect any gases arising
from the drain and in a suitable position above the level of the disinfecting material
in the trough or reservoir the tubular body or stem is provided with several lateral
slots from which the gases will issue and pass over the disinfecting material whilst
immediately above the lateral slots the tubular body or stem is closed by means of
a web or diaphragm.
The tubular body or stem above the web or diaphragm forms a chamber and is
provided with a screw or other stopper or cap, so that by withdrawing the same,
the disinfecting material may be readily introduced into the chamber, and in order
to conduct the disinfecting material into the annular trough or reservoir, an opening
is provided in the side or bottom of the chamber from which a pipe or conduit leads
the disinfecting material into the trough or reservoir.
In order to protect the annular trough or reservoir and its contents from
descending water or other matter, an overhanging bell or cover is provided which
is fixed with the central tube or stem or other part of the device and is of larger
diameter than the trough or reservoir, so as to permit of the ready escape of the
evaporating disinfecting material, and the commingled gases.
In order to apply the device to existing gulleys or the like, and to render it
readily removeable for repairs or other purposes, the upper end of the tubular stem
has fixed thereto a horizontal bar, and the gulley is fitted upon opposite sides with

page_text: plates or ears fixed thereto by screwing or otherwise, and at their upper part.
notched or slotted to receive the ends of the horizontal bar, or the device might be.
fitted with other means of suspending it in the gulley or the like and adapted to
render it readily applicable to existing gulleys.
In lieu of forming the device separate from the gulley or grating as hereinbefore
described, it may if desired be screwed into a boss cast on a gulley grating, or
clamped thereto by means of plates.
The device may be made in malleable cast 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 employed in connection with ventilated gratings, which
are generally of greater depth than séwer gulleys, it is desirable to increase the
depth of the annular trough, and extend the flaring formation of the lower end of
the tubular stem to the lower edge of the outer wall of the trough, so as to adapt
the same to collect a larger volume of gas, and in some cases, in addition to
extending the flaring mouth of the tubular stem to the outer wall of the trough,
such wall is downwardly extended beyond the flaring mouth in order still further to
improve the action of the device.
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 hereinbefore expressed.
In cases where it is desired to employ dry, powdered, or solid disinfecting
material, provision is made for the removal of the annular trough or reservoir from
the cover in order that the trough may be charged, and for this purpose it is
suspended from a bar or the like by means of hooks or the like upon the inside of
the cover.
Or, in cases where it is desired to employ blocks of disinfecting material, the
annular trough or reservoir may be replaced by any other suitable form of bolder,
whilst still retaining the protecting bell or cover.
By the means hereinbefore described, I am enabled to employ the disinfecting
material in connection with sewer gulleys 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 brought into intimate contact with the
evaporating disinfecting material, whilst at the same time there will be no waste, as
such material is completely protected from descending water or the like.

COMPLETE SPECIFICATION.
Improvements in Means or Apparatus to be employed in connection
with Sewer Gulleys or the like for Disinfecting Purposes.
I MARMADUKE MILLER of the Firm of J. Miller and Company of 124 Commercial
Street Whitechapel in the County of London Wholesale Ironmonger and 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 :-
My invention relates to Improvements in Means or Apparatus to be employed

And in order that the said invention may he more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully to
describe the same.

supporting the disinfecting device.
Figure 11 is a sectional elevation of a further modification and
Figure 12 is a vertical section thereof taken on the line 2-2 of Figure 11.
In the several figures in which like parts are indicated by similar letters of reference
Figures 11 and 12 are drawn to a reduced scale with respect to the other figures
of the drawings.
Referring to Figures 1 to 4 a represents a sewer gulley of ordinary construction
and a represents the ordinary grating.
b represents an annular trough, dish, or reservoir, the object of which is to
contain the disinfecting material, and formed or fixed therewith and centrally
thereof is provided a tubular stem or body which rises a suitable distance above
the reservoir or trough b.
The lower part of this tubular stem or body b' at its junction with the annular
trough or reservoir b is downwardly flared or formed trumpet shape in order to
receive and collect any gases arising from the drain, and in a suitable position
above the level of the disinfecting material in the trough or reservoir 6 the
tubular body or stem b₁ is provided with several lateral slots 63 from which the
gases passing in at the flaring or trumpet mouth of the stem will issue and
pass over the disinfecting material on their way to the outer air whilst immediately
above the lateral slots the bore of the tubular body or stem b' is closed by means
of a web or diaphragm .
The tubular body or stem above the web or diaphragm & forms a chamber b
which at its upper end is closed by means of a screw or other stopper b³ or it might
be a cap, so that by withdrawing the stopper the disinfecting material may be

page_text: readily introduced into the chamber and in order to conduct the disinfecting
material from the chamber b into the annular trough or reservoir b an opening is
provided in the side or it might be in the bottom of the chamber 6 from which a
pipe or conduit & conveys the disinfecting material into the trough or reservoir b.
In order to protect the annular trough or reservoir 6 and its contents from
descending water or other matter an overhanging bell or cover b' is provided
which is fixed with the central tube or stem b¹ or other part of the device and is of
larger diameter than the trough or reservoir b so as to permit of the ready escape
of the vapourised disinfecting material from the trough and the commingled gases
issuing from the vertical slots b².
In order to apply the device to existing gulleys or the like and to render it
readily removeable for repairs or for other purposes the upper end of the tubular
stem has securely fixed thereto by screwing or otherwise a horizontal bar 6**
and the gulley a is fitted upon opposite sides with plates or ears a' fixed thereto by
means of a screw or other bolt or stud a' or otherwise and these ears a² are at their
upper parts notched or slotted to receive the ends of the horizontal bar b**.
It will be evident that the device might be fitted with other means than those
hereinbefore described of suspending it in the gulley a or the like and adapted to
render it readily applicable to existing gulleys.
In the example given at Figure 5, a device is shown adapted to be employed in
connection with ventilator gratings which are usually of greater depth than sewer
gulleys, and for this purpose the depth of the annular trough 6 is increased and the
flaring formation of the lower end of the tubular stem is extended to the
lower edge of the outer wall of the trough b so as to adapt the device to collect a
larger volume of gas than in the previous arrangement.
In the example given at Figure 6 in addition to extending the flaring mouth 61*
of the tubular stem ¹ to the outer wall of the trough b such wall is downwardly
extended at 6* in order still further to improve the collecting action of the device.
In the example given at Figure 7 the device is intended for the employment of
dry, powdered, or solid disinfecting material.
In this arrangement the annular trough is formed separable from the other
part of the device and in lieu of connection the tubular stem b' with the horizontal
bar b** the bell or cover b' is fixed with such bar and the stem is dwarfed and the
annular trough or reservoir b is suspended by means of hooks 68 or other devices
from a bar traversing the bell or cover 6' upon the inside thereof stops 6°* upon
the bar preventing the lateral movement of the trough 6 with relation thereto.
By means of this device the trough or reservoir b may be readily unhooked from
the bar when it is desired to replenish the same with dry disinfecting material
but the foul gases issuing from the top of the tubular stem commingle with the
vapourised disinfecting material in a similar manner to that described with respect
to the previous figures.
Or in cases where it is desired to employ blocks of disinfecting material they may
be carried by the annular trough or reservoir bor the latter may be replaced by
any other suitable form of holder whilst still retaining the protecting bell or
cover 67 and the tubular stem b¹.
Although the device described with respect to Figure 7 is more especially
intended for dry powdered disinfecting material it may if desired be charged with
liquid disinfecting material as will be readily understood but it is generally
preferable to perform this operation when the device is in position in the gulley
hence the means of filling shown and described with respect to the other figures of
the drawings.
In the example given at Figures 8 and 9 is shown a slight modification in the
method of supporting the horizontal bar 6** in the sewer gulley, and in this case in
lieu of the notched or recessed ears a² fixed upon the walls a of the gulley, the
latter are formed with notches or recesses a* therein adapted to receive the ends
of the horizontal bar b**.
•
In the example given at Figure 9 the device is similar to that representel at;

page_text: Figure 5 but in this case the tubular stem 61 is somewhat prolonged and the bell or
cover b' bas formed or fixed therewith a cylinder 67* which together with the bell
or cover b' constitutes a box for the reception of dirt or other extraneous matter, or
in lieu of the cylinder 6* a rectangular box might be substituted.
In this case the gulley is fitted with transverse bars a² and the dirt box 6** is
provided with hooks 6** to engage the bars a³ and thus removeably suspend the
device in position.
In the example given at Figure 10 in lieu of forming the device separate from
the gulley grating as hereinbefore described the tubular stem b' is at its upper end
-screwed into a boss a cast on the gulley grating a' but this device is neither so
convenient nor so practical as the arrangements hereinbefore described in which
the apparatus is loosely supported in the gulley and therefore easily removeable.
In the example given at Figures 11 and 12, another means of fixing the device
with the gulley grating is employed and consisting of clamping bars a' taking
under a flange upon the device, and fixed with the gulley grating a' by means of
screws or bolts a, but this device is also open to the same objections as that lastly
hereinbefore described.
The device may be made in malleable cast 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 as will be readily understood.
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 in cases where it is intended to fill the apparatus in the
manner herein before described with respect to Figures 1 to 6 proper access is given
to the upper part of the tubular stem & for that purpose.
By the means hereinbefore described I am enabled to employ the disinfecting
material in connection with sewer gulleys 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 vapour will by
the peculiar construction of the device be brought into intimate contact with the
evaporating disinfecting material whilst at the same time there will be no waste as
such material 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 I declare that what I
claim is :-
:-
