Year: 1874

page_text: LETTERS PATENT to Thomas Hungate Preston Dennis, of Chelmsford,
in the County of Essex, Horticultural Engineer, for the Invention
of "A NEW OR IMPROVED WATER WASTE PREVENTOR."
Sealed the 28th July 1874, and dated the 3rd February 1874.
PROVISIONAL SPECIFICATION left by the said Thomas Hungate
Preston Dennis at the Office of the Commissioners of Patents,
with his Petition, on the 3rd February 1874.
I, THOMAS HUNGATE PRESTON DENNIS, of Chelmsford, in the County
of Essex, Horticultural Engineer, do hereby declare the nature of the
said Invention for "A NEW OR IMPROVED WATER WASTE PREVENTOR," to be
as follows:-
My Invention is for the use of flushing waterclosets, urinals, or
other purposes where a limit is deemed necessary upon the quantity
to be drawn or discharged at one time; and consists of a cistern
having a partition therein forming 2 compartments, into one of
which the water is allowed to flow direct from the water main, or

page_text: other source through an ordinary ball valve, and by which the supply
is regulated.
A small hole or aperture is formed in the partition above described
through which the water flows into the second compartment or service
boot. A well or box is formed within the service boot; a syphon is 5
also fixed therein with its short leg dipping into the centre of well
or box to within a short distance of its bottom, the longer leg of
syphon is passed through bottom of service boot, and a nozel pro-
vided with suitable connections for attaching the service pipe thereto.
The said nozel is not jointed to end of long leg of syphon, but is 1
made of such convenient size and shape as to convey the water from
leg of syphon to service pipe. This nozel is provided with holes directly
below the end of long leg of syphon, and from which the syphon can be
charged with air (when it is desired to stop the flow of water).
Should the service pipe become trapped for the passage of air there- 1
from have become other ways impeded a disc or plate of somewhat
less area than well or box is fitted round short leg of syphon, and
connected with a rod, pull, and lever, and by pulling which the said
dise or plate is forced down leg of syphon into the bottom of well
or box, and by such motion displaces the water therein, and forces 2
sufficient up the syphon to charge it, and so long as the lever is
held down the syphon will continue to run until the contents of
syphon boot, (together with a small quantity of water that passes
from the one compartment to the other through the small hole in
the division, is discharged, but upon the lever being liberated the disc a
or plate is suddenly raised above inlet of short leg of syphon by a
weight provided on end of lever for that purpose, thus stopping the
further discharge of any water through the syphon.
It will be seen by these arrangements that not only is a perfect
and definite charge of water always at the command of the consumer,
but that by the several precautions before described the interests of
water companies and others in preventing any waste of water is most
perfectly guarded against.
It will be obvius that the said cisterns may be made of any desired
shape or form, or from any material capable of containing water.
I do not confine myself to the precise mode of charging the syphon
with a plate or disc, as herein-before described, but reserve the right

page_text: of accomplishing the same by means of a float to be similarly plunged,
and returning to its possession by its own floating power (thus dis-
pensing with the weight on lever), or any other simple form of plate or
displacer of water may be used to charge the syphon.
I do not claim this as my special right, but I wish it to be clearly
understood that I claim, the use of a syphon as the means of conveying
any given charge of water from a service boot into the service pipe
without having any jointed or continuous connection with it, and I
wish it to be clearly understood that the object for which I claim
this directed but uncontinuous communication from the outlet end of
syphon to the service pipe is that an aperture can be introduced through
the connecting nozel directly below the open end of long leg of syphon,
and thus unfailingly charge the syphon with air simultaneously when
the plate or disc before referred to is suddenly raised above inlet of
short leg of syphon by liberating the lever attached to it for the purpose
of stopping any further discharge of water from service boot through
the syphon.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Hungate Preston Dennis in the Great Seal
Patent Office on the 3rd August 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
HUNGATE PRESTON DENNIS, of Chelmsford, in the County of Essex,
Horticultural Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of February, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Hungate Preston Dennis,
Her special licence, that I, the said Thomas Hungate Preston Dennis,
my executors, administrators, and assigns, or such others as I, the
said Thomas Hungate Preston Dennis, my executors, administrators,
and assigns, should at any time agree with, 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,

page_text: and Isle of Man, an Invention for "A NEW OR IMPROVED WATER WASTE
PREVENTOR," upon the condition (amongst others) that I, the said Thomas
Hungate Preston Dennis, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 Thomas Hungate Preston Dennis,
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 :-
My Invention is for the use of flushing waterclosets, urinals, or
other purposes where a limit is deemed necessary upon the quantity
to be drawn or discharged at one time; and consists of a cistern
having a partition therein forming two compartments, into one of
which the water is allowed to flow direct from the water main or
other source through an ordinary ball valve, and by which the supply
is regulated.
A small hole or aperture is formed in the partition above described
through which the water flows into the second compartment or service
boot. A well or box is formed within the service boot; a syphon is
also fixed therein with its short leg dipping into the centre of well
or box to within a short distance of its bottom; the longer leg of
syphon is passed through bottom of service boot, and a nozzle pro-
vided with suitable connections for attaching the service pipe thereto.
The said nozzle is not jointed to end of long leg of syphon, but is
made of such convenient size and shape as to convey the water from
leg of syphon to service pipe. This nozzle is provided with holes.
directly below the end of long leg of syphon, and from which the
syphon can be charged with air (when it is desired to stop the flow of
water).
Should the service pipe become trapped, or the passage of air there-
from have become otherways impeded, a disc or plate of somewhat
less area than well or box is fitted round short leg of syphon, and
connected with a rod, pull, and lever, and by pulling which the said

page_text: disc or plate is forced down leg of syphon into the bottom of well
or box, and by such motion displaces the water therein, and forces
sufficient up the syphon to charge it, and so long as the lever is
held down the syphon will continue to run until the contents of
syphon boot (together with a small quantity of water that passes
from the one compartment to the other through the small hole in
the division is discharged; but upon the lever being liberated the disc
or plate is suddenly raised above inlet of short leg of syphon by a
weight provided on end of lever for that purpose, thus stopping the
further discharge of any water through the syphon.

page_text: of accomplishing the same by means of a float to be similarly plunged
and returning to its position by its own floating power (thus dispensing
with the weight on lever), or any other simple form of plate or displacer
of water may be used to charge the syphon.
I do not claim this as my special right, but I wish it to be clearly
understood that I claim, the use of a syphon as the means of conveying
any given charge of water from a service boot into the service pipe
without having jointed or continuous connection with it, as herein-
before described; and I wish it to be distinctly understood that the
object for which I claim this directed but uncontinuous communication]
from the outlet end of syphon to the service pipe is that an aperture
can be introduced through the connecting nozzle directly below the
open end of long leg of syphon, and thus unfailingly charge the syphon
with air simultaneously when the plate or disc before referred to is
suddenly raised above inlet of short leg of syphon by liberating the
lever attached to it for the purpose of stopping any further discharge of
water from service boot through the syphon.
In witness whereof, I, the said Thomas Hungate Preston Dennis,
have hereunto set my hand and seal, this First day of August,
in the year of our Lord One thousand eight hundred and seventy- 5
