page_text: LETTERS PATENT to Thomas Lambert, of Short Street, New Cut, and
Obed Wakefield, of 23, Lambeth Terrace, Lambeth, in the County of
Surrey, for the Invention of "IMPROVEMENTS IN APPARATUS FOR DRAWING **

AWD
Sealed the 29th September 1857, and dated the 12th May 1857.
PROVISIONAL SPECIFICATION left by the said Thomas Lambert and Obed
Wakefield at the Office of the Commissioners of Patents, with their
Petition, on the 12th May 1857.
We, THOMAS LAMBERT, of Short Street, New Cut, and OBED WAKEFIELD,
of 23, Lambeth Terrace, Lambeth, in the County of Surrey, do hereby declare
the nature of the Invention for "IMPROVEMENTS IN APPARATUS FOR DRAWING OFF
WATER AND OTHER FLUIDS," to be as follows:-
+
This Invention has for its object improvements in apparatus for drawing off
water and other fluids. For these purposes, two valves on separate spindles,
or otherwise capable of separate action, are used, and they are acted on by the
same lever or handle, which is so arranged that it moves on one or other of
the spindles of the two valves, according as it is for the time being opening
the one valve and closing the other. Each valve has its own seat, and the
working of the combined parts is such, that when one valve is open the other *
will be pressed on its seat by the lever before mentioned.
One end of the lever is at all times pressed downwards by a weight or

page_text: spring, whilst the other end is capable of being depressed by a pull or other
convenient means. This apparatus is combined with a cistern or vessel which
is capable of containing the largest quantity of water or other fluid which it is
intended shall be allowed to be drawn off at one time, and the apparatus is so
arranged, that when at rest or left to itself, the water or fluid will flow from
the source of supply into the cistern or vessel with which the apparatus is com-
bined, and fill such cistern or vessel to the extent desired, which may be regu-
lated by a float or ball where the source of supply is above the cistern or vessel.
When the end of the lever to which the pull is applied is depressed or acted
on, the valve between the source of supply and the cistern or vessel will be
first closed, and then the lever will act on such closed valve as a fulcrum and
open the outlet valve from the cistern or vessel; and if the lever be held down
by the pull sufficiently long, the whole of the water or fluid in the cistern or
vessel may be run off therefrom, or only part thereof may be run off.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Lambert and Obed Wakefield in the Great Seal
Patent Office on the 12th November 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
LAMBERT, of Short Street, New Cut, and OBED WAKEFIELD, of 23, Lambeth
Terrace, Lambeth, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of May, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did; for Herself; Her heirs and successors, give and grant unto us, the said
Thomas Lambert and Obed Wakefield, Her special licence that we, the said
Thomas Lambert & Obed Wakefield, our exécutors, administrators, and
assigns, or such others as we, the said Thomas Lambert and Obed Wakefield,
our 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; and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR
DRAWING OFF WATER AND OTHER FLUIDS;" upon the condition (amongst others)
that we; the said Thomas Lambert and Obed Wakefield, our executors or
administrators, by an instrument in writing under our or their hands and seals,
or under the hand and seal of one of us or them, should particularly describe

page_text: and ascertain the nature of the said Invention, and in what manner the samė
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 Lambert, on behalf of myself,
and the said Obed Wakefield,. do hereby declare the nature of the said Inven-i
tion, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement thereof, reference
being had to the Drawing hereunto annexed; and to the figures and letters'
marked thereon (that is to say)::-
This Invention has for its: object improvements in apparatus for drawing off
water and other fluids: For these purposes, two valves on separate spindles,.
or otherwise capable of separate action, are used, and they are acted on by
the same lever or handle; which is so arranged that: it moves on one or other
of the spindles of the two valves; according as it is for the time being opening,
the one valve and closing the other, or vice versa. Each valve. has its own
seat, and the working of the combined. parts is such, that when one valve is
open the other will be pressed on its seat by the lever before mentioned. One
end. of the lever is at all times pressed downwards by a weight or spring, whilst
the other end is capable of being depressed by a pull or other convenient
means. This apparatus is' combined with a cistern or vessel which is capable
of containing the largest quantity of water or other fluid which it is intended
shall be allowed to be drawn off at one time, and the apparatus is so arranged,
that when at rest or left to itself, the water or fluid, will flow from the source
of supply into the cistern or vessel with which the apparatus is combined, and
fill such cistern or vessel to the extent desired, which may be regulated by a
float or ball where the source of supply is above the cistern or vessel. When
the end of the lever to which the pull is applied is depressed or acted on, the
valve between the source of supply and the cistern or vessel will be first
closed, and then the lever will act on such closed valve as a fulcrum and open
the outlet valve from the cistern or vessel; and if the lever be held down by the
pull sufficiently long, the whole of the water or fluid in the cistern or vessel
may be run off therefrom, or only part thereof may be run off.
Having thus described the nature of our said Invention, we will proceed
more fully to describe the manner of performing the same:-

page_text: nected at the end a¹ to the service main or source of supply. At a² the barrel
is to be connected with a reservoir or receiver of the dimensions suitable for
holding the largest quantity of water desired to be supplied at one time. At
a³ a pipe is to be connected to convey the water to the basin of a water-closet
or other vessel, into which the water contained in the reservoir or receiver con-
nected to the end a² of the barrel a. There are two valves b and c, acted on
by a lever d, in such manner that when one valve is open the other will be
closed, by which means water cannot be drawn direct from the main or source
of supply, but only from the reservoir or receiver connected to the end a² of
the apparatus, aud the size or contents of the reservoir or receiver controls the
largest quantity which can be drawn off by one action of the lever d. The
lever d is weighted at d', and it is acted on by a pull or other instrument. In
Figure 1 the supply valve 6 is open and the outlet valve c is closed by and so
long as the parts remain in this condition the receiver or reservoir will be open
to the supply from the main or other source; but so soon as the valve b.is
closed and the valve c is opened, the whole or any quantity of the water
contained in the receiver or reservoir may be run off at the outlet a³..
Having thus described the nature of our said Invention, and the manner of
performing the same, we would have it understood that we make no claim to
any of the parts separately, nor do we confine ourselves to the precise details ;
but what we claim is the combination of apparatus herein described. .
In witness whereof, I, the said Thomas Lambert, have hereunto set
hand and seal, this Eleventh day of November, in the year of our
Lord One thousand eight hundred and fifty-seven.
