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 do hereby
declare the nature of this invention to be as follows:-
The invention relates to Improvements in Means or Apparatus to be employeď
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 sprincle
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 my present invention is to provide a device whereby the
disinfecting material will be stored beneath the grating so that it will gradually
evaporate and commingle with any issuing gases in the desired manner, to protect
the disinfecting material from being washed away by a downward flush and to
enable the device to be readily replenished when desired..
For this purpose I form on or fix to the underside of the grating a downwardly
extending tube at the lower end of which I provide an open-topped cup dish or
reservoir to contain the disinfecting material and I form the tube at its lower end
with ways or openings communicating with the cup dish or reservoir whilst I
provide the upper part of the tube with a screw or other stopper or cap countersunk
in the grating so that by withdrawing the same the disinfecting material may be
readily introduced therethrough into the cup dish or reservoir.
•
'In order to protect the cup dish or reservoir and its contents from descending
water or other matter I provide an overhanging bell or cover fixed with the tube
or other part of the device and which is of larger diameter than the cup, dish, or
reservoir so as to permit of the ready escape of the evaporating disinfecting
material.
In applying my invention to existing gulley gratings I provide the device at it's
upper part with a plate provided with screw holes by the aid of which it may be
fixed to the underside of the grating or in some cases I form the upper end of the
descending tube with a screw thread and I provide the grating with a corresponding
tapped hole to receive the threaded end of the tube the upper end of the tube in äll
cases being closed by means of a suitable stopper or cap.
"
The device may be made in malleable or other 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.
Although I have described my invention in connection with gulleys or drains
provided with gratings 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
descending tube for the purpose hereinbefore expressed.
'
In cases where it is desired to employ blocks of disinfecting material I may
dispense with the cup dish or reservoir and provide any other suitable form of
holder but 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 in a more effective and economical

page_text: manner then heretofore inasmuch as the disinfectant will continuously give off its
gas or vapour until it is exhausted whilst at the same time there will be no waste as
it is completely protected from descending water or the like.

Improvements in Means or Apparatus to be employed in connection
with Sewer Gulleys or the like for Disinfecting Purposes.
1.
I, MARMADUKE MILLER of the Firm of J. Miller and Company of
124 Commercial Street, Whitechapel in the County of London, Wholesale
Ironmonger 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 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 my present invention is to provide a device whereby the
disinfecting material will be stored beneath the grating so that it will gradually
evaporate and commingle with any issuing gases in the desired manner, to protect
the disinfecting material from being washed away by a downward flush, and to
enable the device to be readily replenished when desired.
For this purpose I form on or fix to the underside of the grating, a downwardly
extending tube, at the lower end of which I provide an open-topped cup, dish or
reservoir to contain the disinfecting material and I form the tube at its lower end
with ways or openings communicating with the cup, dish, or reservoir whilst I
provide the upper part of the tube with a screw or other stopper or cap counter-
sunk in the grating, so that by withdrawing the same the disinfecting material
may be readily introduced therethrough into the cup, dish, or reservoir.
In order to protect the cup, dish or reservoir and its contents from descending
water or other matter, I provide an overhanging bell or cover fixed with the tube
or other part of the device, and which is of larger diameter than the cup, dish, or
reservoir so as to permit of the ready escape of the evaporating disinfecting
material.
In applying my invention to existing gulley gratings I provide the device at its
upper part with a plate provided with screw holes by the aid of which it may be
fixed to the underside of the grating or in some cases I form the upper end of the
descending tube with a screw thread and I provide the grating with a corresponding
tapped hole to receive the threaded end of the tube the upper end of the tube in
all cases being closed by means of a suitable stopper or cap.
In cases where it is desired to employ blocks of disinfecting material, I
may dispense with the cup, dish, or reservoir and provide any other suitable form
of holder but still retaining the protecting bell or cover.
And in order that the said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying drawings more fully
to describe the same.

invention applied thereto.
Figure 2 is a vertical section thereof taken on the line 1-1 of Figure 1.
Figure 3 is an end elevation of the container for disinfecting material and its
cover separately. Figure 4 is a plan thereof.
Figure 5 is a plan of an existing sewer gulley of the ordinary rectangular shape
but showing the method of applying thereto the present invention and
Figure 6 is a plan of the container and cover separately.
Figure 7 is a plan of a circular gulley or drain trap having the present invention
applied thereto.
Figure 8 is a vertical section thereof taken on the line 2-2 of Figure 7, and
Figure 9 is an elevation of the container for disinfecting material and its cover
separately.
Figure 10 is a vertical section of a house drain having the present invention
applied thereto.
Figure 11 is a view similar to Figure 8 but representing a device adapted for
solid or block disinfecting material and
Figure 12 is a similar view representing a modified means for supporting the-
disinfecting block.
In the several figures like parts are indicated by similar letters of reference.
Referring to Figures 1 to 4 a represents an ordinary sewer gulley and
a' represents the grating which is not quite of ordinary form but is provided with
a central square or platform a' of solid metal for the purpose hereinafter
described.
To the underside of the square or platform a² of the grating a' is fixed by means
of a plate or flange b¹ and screws 63 passing through the platform a' and screwing
into the flange b' a downwardly extending tube or stem 6 at the lower end of which
and fixed therewith is provided an open topped cup, dish, or reservoir & adapted to
contain the disinfecting material.
The downwardly extending tube or stem 6 is formed at its lower end with ways
or openings & communicating with the cup dish or reservoir whilst the upper
part of the tubular stem b is provided with a screw stopper 66 or it might be any
other suitable form of stopper or cap countersunk in the square plate or platform a¹
of the grating a¹ so that by withdrawing the stopper 65 the disinfecting material
may be readily introduced therethrough into the cup, dish, or reservoir b³.
In order to protect the cup, dish, or reservoir 63 and its contents 6** from
descending water or other matter passing through the grating a¹ an overhanging
bell or cover is provided which is fixed with the tubular stem bor it might be
with some other part of the device, and this bell or cover 6 is formed of
considerably larger diameter than the cup dish or reservoir 63 so as to afford a
passage between those parts for the ready escape of the evaporating disinfecting
material.
In the examples given at Figures 5 and 6 the invention is shown applied to an
existing gulley grating of ordinary construction.
In this case the upper part of the tubular stem is formed with a plate or flange b¹
adapted to take a bearing beneath the grating a¹ and provided with screw holes and
the central bar a* of the grating a' is provided with corresponding holes through
which screws 6 are passed and screwed into the plate or flange 6 of the tubular
stem b, such plate affording the necessary extended bearing to make a solid..
attachment.

In the example given at Figures 7, 8, and 9, the invention is shown applied
circular gulley and in this case the upper part of the tubular stem bis formed
with an external.. screw thread 6* and the grating a is provided with a
correspondingly tapped hole to receive the threaded end 6 of the tubular stem

page_text: the upper end of the tube b in all cases being closed by means of a suitable
stopper or cap such as .
In the example given at Figure 10, the invention is shown applied to a sink or
analogous house drain.
In this case the cup dish or reservoir 63 for the disinfecting material has fixed to
the underside thereof the ordinary bell 67 which acts in conjunction with an
annular cup a fixed with the gulley casing a.
By this arrangement of parts, the grating a¹ and disinfecting device and bell 67
may when desired be removed bodily from the drain.
In the example given at Figure 11, which illustrates a gulley similar to that
represented at Figure 2, the invention is arranged to accomodate a solid form of
• disinfecting material.
In this case the tubular stem is dispensed with, and the cup dish or reservoir b³
is made in the form of a shallow tray supported by stays b from the bell or cover 6
the tray being so arranged with relation to the cover as to enable the
block of disinfecting material to be readily introduced therein.
This device however possesses the disadvantage that it is necessary to remove
the grating a¹ in order to charge the reservoir or tray 63 and it is therefore more
especially applicable to drains of the smaller class where the grating a¹ may be
readily handled.
In the example given at Figure 12, the tray or reservoir is dispensed with and
the block of disinfecting material is suspended from a hook 68 by means of a
chain the bell or cover extending considerably beyond the block of
disinfecting material and so protecting it as herein before described.
This last arrangement is a simple and inexpensive one and is adapted to be sold
as a cheap attachment to existing drains, and for this purpose in lieu of the
screw it would in some cases be furnished with a bolt or stud and nut and
washer as will be readily understood so as to be easily attachable to the grating of
a common house drain.
The device may be made in malleable or other cast or in wrought iron as
herein before described or it may be made of earthenware or other suitable
material, and it may he formed according to the shape of the gulley in which it is
to be placed and although the invention is described in connection with gulleys or
drains provided with gratings, 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
descending tube or tubular stem or to the cup dish or reservoir for the purpose
hereinbefore expressed.
By the meaus hereinbefore described the disinfecting material may be employed
in connection with sewer gulleys and other drains 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, whilst such vapourised disinfecting
material will find its way out from under the bell or cover and will be brought
into intimate contact and caused to commingle with the foul gases rising from the
gulley whilst at the same time there will be no waste of disinfectant as it is by the
hell or cover 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 :-
"
1. In a disinfecting apparatus for sewer gulleys or the like the combination
of an open reservoir or other holder for disinfecting material adapted to be
suspended or fixed in the mouth of a drain and a bell or cover of larger area
than the reservoir for protecting the contents of the same against descending water
or other matter whilst permitting the escape of the vapourised disinfectant
substantially as herein shown and described.
2. In a disinfecting apparatus for sewer gulleys or the like the combination of an
open reservoir or holder for disinfecting material adapted to be suspended or fixed

page_text: in the mouth of a drain, a tubular stem at its lower end communicating with the.
reservoir and at its upper end provided with a stopper or cap and a bell or cover-
carried by such stem and of larger area than the reservoir, for protecting the
contents of the same against descending water or other matter substantially as
herein shown and described.
3. In a disinfecting apparatus for sewer gulleys or the like the combination with
the gulley grating of a tubular stem at its upper end fixed with the grating and
closed by a stopper, an open reservoir or holder for disinfecting material fixed at
the lower end of the stem, communicating ways between the stem and the reservoir
and a bell or cover carried by the stem and of larger area than the reservoir for
protecting the contents of the same against descending water or other matter
substantially as herein shown and described.
