I, EDGAR WILLIMAN JOBSON, of Derby, in the County of Derby, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS FOR CONTROLLING THE SUPPLY OF WATER TO WATERCLOSETS, URINALS;
AND SUCH LIKE PLACES, AND IN EFFECTING THE MEASUREMENT OF THE WATER
SUPPLIED FOR SUCH AND OTHER PURPOSES," to be as follows:—
The object of one part of the Invention is to insure a definite supply
of water in the flushing of waterclosets, urinals, and such like places,

page_text: without support from water below, keeps the valve in its seat until it is
again lifted as stated.
The measurement of the quantity of water supplied for such and other
purposes is obtained by the use of another cistern from which the
desired supply is now drawn, such secondary cistern being supplied from
the first cistern by a pair of floats, one of which floats by descending
with the level of the water in that secondary vessel acts to remove a
catch or tappet support to the arm of the other float, so as to release
that other float, and by a connecting rod cause a supply from the other
cistern, and so on.
The first supply cistern to the secondary one may be varied as to its
arrangement.
This measurement may also be obtained by the vessel used to fill the
upper part of the syphon being supported on pivots placed out of the
centre of gravity of such vessel, but with weight adapted to keep its
longer end with the syphon attached thereto raised, until water regulated
to flow therein interferes with the centre of gravity of that vessel to
cause the depression of the longer end thereof, and the filling of the
upper part of the syphon. The flow of this water is regulated by a float
in the supply vessel or chamber.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edgar Williman Jobson in the Great Seal Patent
Office on the 19th September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDGAR
WILLIMAN JOBSON, of Derby, in the County of Derby, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of March, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Edgar Williman Jobson, Her special license
that I, the said Edgar Williman Jobson, my executors, administrators,
and assigns, or such others as I, the said Edgar Williman Jobson, my
executors, administrators, and assigns, should at any time agree with,

page_text: and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend; within the United Kingdom of Great Britain and Ireland
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN APPARATUS FOR CONTROLLING THE SUPPLY OF WATER TO WATERCLOSETS, &
URINALS, AND SUCH LIKE PLACES, AND IN EFFECTING THE MEASUREMENT OF
THE WATER SUPPLIED FOR SUCH AND OTHER PURPOSES," upon the condition
. (amongst others) that I, the said Edgar Williman Jobson, my executors
or administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the 1
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 Edgar Williman Jobson, do hereby 1
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement thereof, that is to say :-
-
The object of one part of the Invention is to insure a definite supply
of water in the flushing of waterclosets, urinals, and such like places.
For this purpose the outlet passage from the supply cistern to the
delivery is provided inside such supply cistern with a syphon tube or a
tuble capable of acting as such on depression of the arch or upper part
thereof below the water line, or on the supply of such part of the syphon
with water to create a current in it. This depression is effected by
the lever or other connection for opening the passage acting on the
syphon tube, and the syphon tube is according to one class of arrange-
ment. capable of the desired depression below the water line by being
formed of vulcanized or prepared india-rubber, or other flexible material,
or partly of metal and partly of such flexible material, or by its turning
on a pivot or hinge. The lever, or other connecting means, when
depressing the syphon to supply a watercloset, or such like place, acts
by a connection to support the ball lever of the supply tap to this
supply cistern, or this supply may be otherwise effected, so that no fresh
water may enter that cistern until the syphon passage has been allowed
to rise again, and by the outlet passage being so much larger than the
supply to this supply cistern the supply cistern will at onco empty itself
to the level of the mouth of the syphon, and admit air thereto, pre>
.

page_text: the accompanying Drawings proceed to describe means pursued by mẹ
in carrying the same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a longitudinal section, Figure 2 a transverse
section, and Figure 3 a plan view of apparatus arranged according to
one part of my Invention. a is the supply cistern, which is supplied
with water from an adjoining cistern 6 through the pipe c and passage c¹.
The cistern b, as shown, is supplied by means of the tap d, the shutting of
which is governed by the ball lever e, as is well understood, or the supply
to the cistern 6 may be by other suitable means. The line fis intended
to represent the level of the water in the cistern a when that cistern is
filled; is the outlet passage of supply from this cistern a to the water-
'closet, urinal, or other such like place to be flushed; and it will be seen
that the part thereof within the cistern a is formed into the syphon
tube g³, g³, opening by the mouth g³ into the cistern a. The part g³ of the
syphon is connected to the passage g by the piece of flexible tubing g³, so
that the part o³ may readily be raised and lowered in the vessel a. In
place however of employing a piece of flexible tubing the end g³ may be

page_text: "
connected to the passage 9 by a rigid pipe and a jointed water-tight
connection. The outer end 9 of this syphon pipe is connected by the
link / to the lever i, which is supported so as to be capable of rocking
on the centre of motion & carried by the fixed bearing . One end of
this lever i has applied to it the weight to act as a counterbalance
with a tendency to keep the other end of that lever raised, lifting the
neck 4 of its syphon 9* above the level of water in the cistern a. To
the end is connected a chain or other suitable connecting means t³, by
which the outer end of the lever i may be drawn downwards, at the
same time lifting the weight end, and when só acted upon the end g² of
the syphon will be depressed, so as to bring the neck 4 entirely below
the surface of the water in the vessel a when the water in the vessel a
flowing over that neck will drive the air out of the pipe g, and the water
will continue to flow down that pipe from the cistern a until all the
water in that cistern to the level of the opening 7³ has passed down the
pipe 9, and air is again permitted to flow into the syphon by the
passage 9. I have stated that water enters the compartment a by the
passage o¹ through the pipe c from the chamber 6. The pipe c, as
shewn, is formed of india-rubber tubing; but this may be varied, so
long as it is capable of movement for the raising and lowering of its
outer end c³, and this outer end c³ is by a link c³ connected to the
weighted end of the lever i, so that when that lever is in a state of
repose, as shown, the open end c³ of the pipe c is below the level of the
water in the vessel'b, and consequently water may freely pass from the
chamber or compartment to the chamber a to keep that chamber a
supplied, but when the weighted end of the lever i is raised to depress
the syphon g³, and allow the water to flow from the vessel a, as just
described, the open end c³ of the pipe c will be raised above the upper
surface of the water in the vessel b, so as to prevent water passing from
the vessel b to the vessel a until the end of the lever i is relcased, a
and allowed to rise.
•
Figures 4, 5, and 6 show a modification of this part of the improvements
in which the parts constituting the syphon are stationary; g is the
supply pipe to the watercloset, urinal, or other place, and the upper
open end of this tube * opens into a chamber j, which is closed from 3
the vessel a except by the passage k, which is closed by the conical
plug & affixed to the lower end of the tube ³ and suspended by a link Z
from the weighted end of the lever i. The other end of the lever i.

page_text: carries the weight, or close chamber, or displacer m, which is adapted
when that end of the lever i is drawn downwards to cause the water
in the vessel a by displacement to rise therein, and then as the plug k¹
will also be raised, water will freely flow into the chamber; to the upper
5 end of the pipe g, displacing the air therein and causing that pipe and
chamber to act as a syphon tube to draw off the water from the
chamber a until the water in that chamber is exhausted to the level of the
passage and air flows therein, or the lever i is set free for the weighted
end of it to descend, thereby at once raising the displacer mout of
the water in the chamber a and allowing the plug ³ to close the
passage k; when air will flow down the tube ³ into the syphon chamber j
to stop the flow of water by the passage g.
I will now describe an arrangement of apparatus for effecting the
measurement of water supplied for various purposes.
.
Figuro 7 shows a side sectional view of apparatus according to this part
of the Invention. Figure 8 is a transverse section of the same, and
Figure 9 a plan view. In this case the cistern a with its parts serves
only as a means of supply to another cistern B. Parts which are
similar in these Figures to those already described are marked with the
letters of reference already employed. The cistern B is that which now
forms the supply for the waterclosets, urinals, or other purposes, by
suitable pipe or pipes, not shown, and this secondary cistern B is
supplied from the cistern a by a moveable syphon arrangement g³, such
as already described, operated by a pair of floats C and D. The float C
is suspended by chain or it may be by band or other flexible connection
O passed partly round and suspended from the tappet E (see also
Fig. 10) which is supported to turn on the fixed axis E¹, and is formed
with a projection E to rest against a stationary projection E³ when the
ball O is raised by the cistern B being supplied, and whilst in that
position the tappet E is capable by its notched part E' of sustaining the
arm D' of the float D. But so soon as the float C has descended to a
certain depth in the cistern B that float C acts by its chain C¹ to draw
round the tappet E, so that its notch E is then withdrawn from the
support of the arm D¹ of the float D, releasing that float, the arm of
which will then act on the link F suspended from the lever i to draw it
downwards and thus bring the syphon 9³ into operation to refill the
chamber B. As that chamber fills the arm of the float D will in
rising act on the tappet E to place it in position, as before, and so on.

page_text: The quantity each time supplied to the vessel B being definite, and a
click or other driving apparatus being applied to the moving parts may
give motion to a ratchet or other suitable wheel, and thence to a train
of wheelwork for indicating the successive quantities drawn off.
Having thus described my Invention, and means which I adopt in ||
carrying the same into effect, I would have it understood that what
I claim is,-
First. The arranging or combining parts whereby the supply of water
to waterclosets, urinals, and such like places, is controlled by syphon
arrangements acting substantially as described in respect of Figures
1, 2, and 3.
Secondly. I claim the arranging or combining parts whereby the
supply of water to waterclosets, urinals, and such like places is
controlled by syphon arrangements acting substantially as described in
respect of Figures 4, 5, and 6.
Thirdly. I claim the arranging or combining means for the measure-
ment of the quantity of water supplied, substantially as described in
respect of Figures 7, 8, and 9.
Fourthly. I claim the so arranging or combining parts forming
syphons that the same may be brought into use to supply water to
waterclosets, urinals, and such like places, by filling the necks thereof
with the water to be supplied in order to displace the air therefrom,
substantially as described.
In witness whereof, I, the said Edgar Williman Jobson, have
hereunto set my hand and seal, this Eighteenth day of September,
in the year of our Lord One. thousand eight hundred and
seventy-three.
