as onliest to

page_text: my apparatus, which consists of a cylinder of metal to contain the dis-
infecting fluid. In this cylinder and near the bottom thereof I place a
small pump, with a valve at the bottom. To the side of this pump,
which is fixed to the side of the aforesaid cylinder, I connect a small
pipe, which extends to the top of the pan, and at a short distance up the
said pipe I fix another valve. The rod of the pump is connected to the
lever that works the plug for flushing. The effect will be as follows:-
Upon pulling up the plug the plunger of the pump will be drawn
slightly up, and thereby cause a certain quantity of the disinfecting fluid
to be drawn in the said pump by means of the aforesaid valve at the
bottom thereof, and upon the plug being let down again the plunger will
also go down, and close the aforesaid valve at the bottom of the pump,
at the same time causing the valve in the pipe to open, and thereby
inject as much. of the disinfecting fluid into the pan (as was allowed to
enter the pump) after it is flushed, but while the water therein is in
motion, thereby thoroughly mixing and charging the water with the
disinfecting fluid. The pipe must be fully charged before it is ready for
use; this may be done by working the plug several.times.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Morcombe Bromley Baker in the Great Seal 2
Patent Office on the 2nd January 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MORCOMBE BROMLEY BAKER, of Lennox Road, Southsea, in the County
of Hants, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 2
Letters Patent, bearing date the Second day of July; in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors give
and grant unto me, the said John Morcombe Bromley Baker, Her special
licence that I, the said John Morcombe Bromley Baker, my executors, 3
administrators, and assigns, or such others as I, the said John Morcombe
Bromley Baker, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain 3

page_text: and Ireland, the Channel Islands, and Isle of Man, an Invention for
"AN IMPROVED DISINFECTING AND DEODORISING APPARATUS FOR WATERCLOSETS AND
OTHER PURPOSES," upon the condition (amongst others) that I, the said
John Morcombe Bromley Baker, my executors or administrators, by
an instrument in writing under my, or their, or one of hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said John Morcombe Bromley Baker,
do hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say:-
This Invention consists in constructing an apparatus for the purpose
of injecting into the pan of a watercloset or urinal a given quantity of
any suitable disinfecting fluid.
The following is an example of my said Invention as applied to water-
closets:-Under the seat of the closet I place my apparatus, which
consists of a cylinder of metal to contain disinfecting fluid. In this
cylinder and near the bottom thereof I fix a small pump barrel, fitted
with an elastic or flexible plunger or bucket. To this pump barrel,
which is fixed to the bottom of the aforesaid cylinder, I connect a small
pipe, which extends to the top of the pan of the closet, and at a short
distance up the said pipe I fix a valve, and I connect the rod of the
aforesaid pump to the ordinary lever that works the plug for flushing
the pan of the closet, the effect of which is as follows:-Upon pulling
up the plug the plunger of the pump will be raised, and thereby allow
a small quantity of the disinfecting fluid to enter the aforesaid pump
barrel, and upon the plug being forced down the plunger of the pump
will also descend, and force the disinfecting fluid that is beneath the
plunger up the pipe leading from the pump to the pan of the closet,
at the same time causing the valve in the said pipe to open and allow
a certain quantity of the disinfecting fluid to be injected into the pan
during the flushing thereof and whilst the water therein is in motion,
thereby thoroughly mixing and charging the flushing, water with the
disinfecting fluid. The aforesaid pipe must be fully charged before it

page_text: is ready for use, this may be done by working the plug up and down
several times.
In order to explain the details of my said Invention and their
functions, I will now proceed to describe the illustrative Sheet of
Drawings accompanying these Presents by reference to the numeral
ficures and letters marked thereon, as follows:-
DESCRIPTION
VF
Figure 1 represents an elevation of my improved apparatus as it would
appear when applied to the pan of a watercloset; Figure 2 is a trans-
verse and vertical section of my said improvements; Figures 3 and 4
represent detached parts herein-after particularly described and referred
to. On each of the above-mentioned Figures similar letters of reference
are employed to denote corresponding parts.
.
A marks a cylinder or reservoir of metal or earthenware, with a loose
top B for charging it with disinfecting fluid; C is a pump barrel, smooth
on the inside; a is a flange for fixing the barrel C to the bottom of the
reservoir A; and 6 is a foot cast on the said barrel for fixing it to the
floor. D is an india-rubber plunger or bucket fitting loosely within the
barrel C; and E is a rod connected by its lower end to the plunger D,
and by its upper end to a fork shaped piece G, into which the rod E is
screwed, and may be adjusted so as to either lengthen or shorten the
stroke of the plunger D for discharging any required quantity of the dis-
infecting fluid from the reservoir, and inject it into the pan, as before
stated. H is a metal pipe screwed or otherwise fixed in the barrel O by
its lower and curved end; the upper end of the pipe H is fixed in a
casting I, which carries a valve d on its upper edge. The construction
of this valve and manner of holding it in position is as follows:-The
valve d is made of vulcanized india-rubber, with a slit e at its apex, as
represented at Figure 3. The flanged part of thereof should be made
with a plie of woven or textile fabric at such part to prevent distortion
or alteration of shape when the valve is screwed in its place, as at
Figure 2, where K marks a screwed connecting piece, the flanged part g
whereof screws tightly on to the flanged part f of the valve d, thereby
securely fixing it water-tight in proper position. L is another metal pipe
(copper by preference) connected at one end by the union to the
piece K, its other end leading into an ordinary closet pan M, the pipe L

page_text: passing over the edge of the pan and between it and the seat N, as repre-
sented at Figure 1. The valve d is employed to prevent the return of
the disinfecting fluid into the reservoir A when the plunger D is at rest,
thereby keeping the pipes H and L always full of the disinfecting fluid,
and obviating the necessity for filling the said pipes with the disinfecting.
fluid at each downward stroke of the plunger of the pump. O marks the
ordinary water scatterer of a closet.
I would here remark that in order to prevent the formation of salts
within the pipe L when the apparatus is at rest, and which if not pre-
vented would obstruct the free passage of the disinfecting fluid, I fix an
elastic tube P on that end of the pipe L which enters the pan, and I
form the outer end of the tube P flattened, as at i, Figure 4, the effect
of which is to close this end of the pipe, and exclude the entrance of air
thereinto. Q, R, are the rod and lever commonly used in waterclosets
for actuating the plug by which the water passes for flushing the
pan M.
For the purposes of my Invention I connect the parts Q and R
with my aforesaid improvements in the following manner:-T marks a
standard fixed to the floor of the closet, to the upper end of this
standard I pivot at k one end of a rod U, and connect this rod at
to the fork G, and finally connect the other end of the rod U to the
lever R by links m. By thus connecting the several rods and levers
together, and imparting upward movement to the rod Q, the rod E and
plunger will be raised during the opening of the plug by which the water
passes for flushing the pan. A reverse movement of the rod Q will cause
the disinfecting fluid to be mixed with the water as it enters the pan,
and thus effectually accomplish the object of this Invention.
The injection of a measured quantity of the disinfecting fluid into a
receptacle, as above described, may be applied to urinals constructed
with a pull valve, or on the well-known principle of injecting a regulated
quantity of water by a treadle lever, operated by the feet of the person
using the urinal.
Having now described the nature of my said Invention for "An
Improved Disinfecting and Deodorising Apparatus for Waterclosets and
other Purposes," and in what manner the same is to be performed, I wish
it to be understood that I am aware the supply of disinfecting fluid to
waterclosets has been suggested. I do not therefore claim generally

page_text: such supply, nor do I claim as my Invention the exclusive use of any of
the separate parts above described and referred to, except in so far as
the same may be employed in combination and for the purposes of my
said Invention; and I hereby declare my Invention to consist in and I
claim, apparatus constructed and arranged as above described and repre-
sented, whereby the disinfecting fluid may be injected in an ascertained
and measured quantity, and caused to mix with the flushing water
during its flow into the pan of the closet simultaneous or after the
closing of the pan.
In witness whereof, I, the said John Morcombe Bromley Baker,
have hereunto set my hand and seal, this Second day of January,
in the year of our Lord One thousand eight hundred and seventy-
three.
