PROVISIONAL SPECIFICATION.
Improved Automatic Disinfecting Apparatus for Sewers, Drains,
Water-closets, Urinals, and the like.
We, FREDERICK CLARKSON, of 175 High Street, Brentford, in the County
of Middlesex Salesman, THOMAS LANGDON, of 235 High Street Brentford, in the
County of Middlesex, Salesman, ARTHUR MOORE, of 2 Florence Villas Algar
Road Isleworth, in the County of Middlesex, Baker and FRANK MOORE,
133 Cator Street Peckham, in the County of Surrey, Engineer do hereby declare
the nature of this invention to be as follows:-
Our invention has for its object the provision of means for supplying auto-
matically to water-closets, urinals, drains, sewers, and the like, a certain quantity
(which may be regulated) of any suitable disinfectant every time the closet etc.
to which our apparatus is attached, is flushed. To carry out this invention, we
take a tank, or other suitable reservoir, and fit a syphon pipe with regulating
valve and air pipe, to which is attached (or may be formed with the syphon) a
collecting cup or chamber, to which is connected the short arm of syphon, the long
arm of syphon is connected with the water-closet, urinal, drain, sewer, or flushing
apparatus or other water supply connected to same, so that the flow of water or sewage,
passing the long arm of syphon causes a suction action, by which the disinfectant
contained in the collecting cup or reservoir, will flow and mix with the contents
of water-closet, urinal, drain, sewer etc. The collecting cup or reservoir may be
wholly or partly of glass.

COMPLETE SPECIFICATION.
Improved Automatic Disinfecting Apparatus for Sewers, Drains,
Water-closets, Urinals, and the like.
We, FREDERICK CLARKSON, of 175 High Street, Brentford, Shopman,
THOMAS LANGDON of 235 High Street, Brentford, Boot Salesman, ARTHUR
MOORE of 2 Florence Villas, Algar Road, Isleworth Baker, and FRANK MOORE
of 133 Cator Street, Peckham, 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 :-
Our invention is designed to provide a convenient means for an automatic
supply of fluid disinfectant to water closets, urinals, drains, and the like which
are provided with a flush of water, the said disinfectant being mixed with said flush
when drawn.
To carry out the invention we take a reservoir of any suitable shape size or
material, and fit thereto a delivery cup or measuring chamber into which the said
disinfectant is caused to drip slowly until the same is filled. Into this cup we
conduct the short arm of a syphon; the long arm of which is connected to the
flush pipe of the closet in such a way that when a flush is drawn the descending
water causes a suction in the syphon, and draws off automatically the disinfectant
stored in the cup.
To prevent the suction drawing off disinfectant from the reservoir, we furnish

page_text: the said cup with an air pipe, so that when the syphon has emptied the cup it will
draw air only, until the cup is slowly refilled by the drops from the reservoir.
Naturally the cup should be below the level of the reservoir and we make it
preferably of glass so that it can be seen when the reservoir is empty, by the
absence of fluid in the cup. The size of the cup regulates the amount of disinfectant
employed at each flush.
Instead of a separate cup the syphon can be provided with a curved enlarged
end to serve as the measuring chamber.
We will now describe the invention with reference to the accompanying drawings
in which
Fig. 1 shows a plan view of a reservoir of semi-circular shape with a recess a',
which allows it to be fixed over the flush pipe. This reservoir is fitted with a
cover a².
Fig. 2 shows a section of the same on the line 1-2 Fig. 1.
Fig. 3 shows the air tube d, detached from the cup b, with notch d', at side
through which the fluid drops into the cup.
Fig. 4 shows a covered. reservoir with the syphon bend c³, serving as a measuring
chamber.
Fig. 5 shows a circular reservoir preferably of glass and a cup 6, of more
ornamental pattern, formed of a glass tube with brass end piece b', which is screwed
on to the end of the tube c².
In this case an opening is formed in the side of the tube for the.syphonage.
a, is the reservoir. a', is the recess in the back of a. a, is the cover. b, is
the cup or measuring chamber with an air-tight cover through which pass the two
pipes c, and d., is a brass end piece on the cup. c, is the syphon. c, is the
long arm pipe of the syphon. c², is the short arm pipe of the syphon. ³, is the
enlarged bend of the syphon serving as the measuring chamber. d, is the air pipe
fitted into the cup b. d, is the notch in d, for allowing the fluid to drop into the
cup. The notch being A shape the flow of liquid is regulated by screwing the
pipe d, more or less into the cover of b. e, is the flush pipe.
The method of use is as follows:-
―
The reservoir being fixed contiguous to the flush pipe, and the end of the syphon
pipe connected thereto, and the joint made airtight with white lead or in any well
known way, the reservoir is filled with any fluid disinfectant such as a solution of
carbolic acid and hot water, say one part of acid to fifty parts of water. The air
pipe is then screwed in sufficiently to regulate the flow of disinfectant into the cup.
When the flush takes place the contents of the cup will be drawn with the flush
water into the water closet or urinal.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. An automatic delivery apparatus for fluid disinfectants consisting of a
reservoir or container, a covered cup or measuring chamber with air pipe and
regulable supply notch and a syphon with short pipe connected to cup, and long
pipe connected to flush pipe, as herein described and set forth.
2. In a delivery apparatus for fluid disinfectants the covered reservoir a, the
covered cup or measuring chamber, the syphon c, the air pipe d, with notch d',
as herein described and set forth.
