page_text: LETTERS PATENT to George Nobes of 27 Dudley Grove Harrow Road,
Paddington in the County of Middlesex, Sanitary Engineer for an Invention
of "IMPROVEMENTS IN DEODORIZING AND DISINFECTING APPARATUS"
PROVISIONAL SPECIFICATION left by the said George Nobes at the Office
of the Commissioners of Patents on the 30th August 1882.
GEORGE NOBES of 27 Dudley Grove, Harrow Road, Paddington, in the
County of Middlesex, Sanitary Engineer,
" IMPROVEMENTS IN DEODORIZING AND
DISINFECTING APPARATUS"
My Invention relates to Improvements in deodorizing and disinfecting apparatus
for water-closets or urinals, drains or sinks and consists of a regulating supply
cistern or tap, combined or separate. My improved apparatus is so designed as to
be attachable to every description of water-closet, urinal, sink or drain, where
other similar appliances cannot be so effectively or conveniently fixed, and to
operate in such a manner as to measure a charge of disinfecting fluid for injection
into the closet pan, urinal, sink or drain each time the valves or taps are used.
One modification of my improved apparatus consists of a cistern of any
convenient size and shape to contain disinfecting fluid and which is placed either
by the side, underneath or on the top of a waste-preventer or other supply cistern
worked with a ball-tap or valve for regulating the supply of water to the closet or
urinal, or alone without connection with any other cistern.-Attached to and at
the bottom of this cistern, or down the pipe leading from the cistern to the urinal,
is an enclosed box of convenient size and shape (hereinafter called "the holder")
to measure the charge of disinfecting fluid. The holder is filled by raising a
plunger within it made of suitably heavy material, and which being raised, allows
the disinfecting fluid to flow into the holder by means of perforations made in the
side of the holder at a convenient distance from the bottom of it, so as to measure
the charge required. This plunger is raised by the ordinary rod or chain attached.
to a lever working on the top of the cistern in connection with the pull-down rope

flows into the closet pan or urinal and the plunger is raised, allowing the fluid to
enter and fill the holder. When the chain is released, the water stops flowing, and
the plunger descends by its own weight and forces the charge of disinfecting fluid
through a small pipe into the closet pan or urinal.
Another modification of my Invention consists of a twin-tap worked by
cog-wheels and which is applicable equally to regulating the supply of water to
the closet or drain and to measuring and supplying the fluid for disinfecting
purposes. The tap can be opened and shut by means of an ordinary gas or
water key.
My improved apparatus may either be covered or uncovered.
SPECIFICATION in pursuance of the conditions of the Letters Patent and of
an Order of the Lord Chancellor filed by the said George Nobes in the Great
Seal Patent Office on the 13th March 1883.

My Invention relates to Improvements in deodorizing and disinfecting apparatus
for cisterns Waste preventors water closets Urinals drains and sinks and consists
of a regulating supply cistern or taps combined or separate My improved
apparatus is so designed as to be attachable to every description of cistern waste
preventer Water Closet Urinal sink or drain and also in cases where appliances of
a like character cannot be so effectively or conveniently fixed and to operate in such
a manner as to measure a charge of disinfecting fluid for injection into the cistern
waste preventer closet pan Urinal sink or drain each time the valves or taps
are used
One modification of my improved apparatus consists of a cistern of any
convenient size and shape to contain disinfecting fluid and which is placed
either by the side underneath or on the top of or in connection with or as
part of a waste-preventer or other supply cistern worked with a balltap or
valves for regulating the supply of water to the closet or urinal or alone
without connection with any other cistern-Attached to and at the bottom
of this cistern or down the pipe leading from the cistern to the urinal is an
enclosed box of convenient size and shape (hereinafter called "the holder") to
measure the charge of disinfecting fluid The holder is filled by raising a
plunger or valves within it made of suitably heavy material and which being
raised allows the disinfecting fluid to flow into the holder by means of a per-
foration or perforations made in the side of the holder at a convenient distance
from the bottom so as to measure the charge required This plunger is raised by

page_text: the ordinary rod or chain attached to a lever working on the top of the cistern in
connection with the pull-down rope or chain of the waste-preventer or cistern
When that chain is pulled the water flows into the closet pan or urinal and the
plunger is raised allowing the fluid to enter and fell the holder When the chain is
released the water stops flowing and the plunger descends by its own weight and
forces the charge of disinfecting fluid through a small pipe into the closet pan or
Urinal
Another modification of my invention consists of a double tap or a triple tap
worked by rotating cogs or other gear and which is applicable equally to regulating
the supply of water to the closet or drain and to measuring and supplying the
fluid for disinfecting purposes The tap can be opened and shut by means of an
ordinary gas or water key or ball or otherwise
My improved apparatus may either be covered or uncovered
And in order that my said invention may be clearly understood reference is
hereby made to the accompanying drawings, in which similar letters of reference
indicate corresponding parts in the several figures and which drawings represent
several methods of carrying out my said invention
Fig. 1 represents a mode of disinfecting the water in the supply cistern and
which arrangement is suitable for large establishments a is the water cistern. bis
a small cistern containing disinfecting fluid. c is the ordinary supply controlled by
a ball valve as usual d is an additional ball for controlling the admission of a
certain quantity of disinfecting fluid to the cistern a. e is a "holder" which holds
a definite quantity of disinfecting fluid-This holder is fitted with two cocks e¹ e²
When the ball d falls as seen in Fig. 1. e' is turned off and e². is turned on
holder e then fills with disinfecting fluid, the air escaping by the small air pipe e³.
When the cistern is again filled up from the supply c. the ball d rises and shuts
off e². and opens e¹. This causes the fluid contained in e to fall into the cistern a
and this quantity of fluid is made of sufficient strength to render the water in a
disinfectant. f is the pipe leading to the closet, urinal, sink or other article to be
disinfected.
The
Fig. 2 (on a larger scale) represents a small cistern containing disinfecting fluid.
A small cylindrical holder e is fitted with a solid heavy piston g truly turned to fit
the cylinder. This piston is raised by the lever h. this operation causes the fluid
to enter the cylinder by the holes xx. When the lever is "let go" it descends
and the piston g at the same time expels the fluid from e through the pipe f which
leads to the article to be disinfected The chain cord or rod h'. may be operated
by a spring seat, spring board door or by hand as desired the object being to let a
small quantity of disinfecting fluid enter the pan &. immediately after the ordinary
flushing has taken place is for admission and emission of air
I sometimes arrange the end of the pipe f so that it surrounds or partially
surrounds the upper end of a closet pan or urinal such pipe having a number of
small holes in order to distribute the after flush of disinfecting fluid.
e is
Fig. 3 represents another mode of carrying out my said invention The pipe c leads
from any ordinary water supply and the pipe fleads to any apparatus requiring
be occasionally flushed b'. leads from a cistern containing disinfecting fluid
a holder similar to that in Fig 1. k is a pipe leading from e to f. iii are three
segmental portions of toothed wheels geared together It will be readily seen
that the holder e is empty as shewn but on turning on c'. e². will be also turned
on and el. will be turned off e will then be filled with fluid and will so remain
until c'. and e. are again turned off when the fluid will immediately pass through k
to and impart the necessary disinfecting afterflush e is the air pipe. Levers
and links may be substituted for the toothed Segments i ii
Fig. 4 is a modification of Fig. 2 the holder e being in the form of an internal
cistern When the lever is pulled the valve e' is closed and e². is opened. This
causes the holder to fill. On releasing the valve e² is closed and the valve e¹ is
opened, in which latter position it is shewn in the figure 4.
Fig. 5 shews my said invention as an addition to an ordinary waste water

page_text: preventer m is the waste preventer fitted as usual, the ball n being held up by
the link o during the process of flushing At the same time the lever raises g and
the disinfecting after flush is effected as described with respect to Fig. 2
The waste-water preventer (Fig. 5) and the cistern b-may be made in one casting
if preferred, and the holder e (Fig 4) may be substituted for that shewn in Fig. 5
Having thus particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I claim :-
1. The use and manufacture of disinfecting apparatus arranged and operating
substantially as herein before described and shewn in Fig 1 of the drawings
2 The use and manufacture of the holder together with the triple tap or three
cocks simultaneously operating substantially as hereinbefore described and shewn
in Fig. 3 of the drawings
3. The use and manufacture of holders fitted and operating substantially as
herein before described and shewn in Figs. 2. 4 and 5 of the drawings
4 The respective combinations of parts together forming my improvements in
deodorizing disinfecting and after flushing apparatus constructed arranged and
operating substantially as herein before described and shewn on the drawings or
any mere modification thereof.
In witness whereof I the said George Nobes have hereunto set my hand
and seal this twelfth day of March in the year of our Lord One thousand
eight hundred and eighty three.
