of Golden Lane, in the Parish of Saint Giles, Cripplegate, in the City of

WHEREAS His most Excellent Majesty King George the Third, by His
Royal Letters Patent under the Great Seal of Great Brittain, bearing date
at Westminster, the Seventeenth day of May, in the twenty-third year of His
reign, did give and grant unto me, the said David Riz, my executors, admi-
nistrators, and assigns, His especial licence, full power, sole priviledge and
authority, that I, the said David Riz, my executors, administrators, and assigns,
and every of them, by myself and themselves, or by my and their deputy or

within that part of His Kingdom of Great Britain called England, His

said David Riz, my executors, administrators, or assigns, or any of them,
should in my or their discretion seem meet, and that I, the said David Riz,

page_text: my executors, administrators, and assigns, should lawfully might have and
enjoy the whole benefit, commodity, and advantage from time to time coming,
growing, accruing, and arising by reason of the said Invention, for and during
the term of years therein mentioned, to have, hold, exercise, and enjoy the said
licence, powers, priviledges, and advantages therein-before granted or men-
tioned to be granted, unto me, the said David Riz, my executors, administrators,
and assigns, for and during and unto the full end and term of fourteen years
from the date of the said Letters Patent next and immediately ensuing, and
fully to be compleat and ended, according to the Statute in such case made and
provided; in which said Letters Patent is contained a proviso, that if I, the
said David Riz, should not particularly describe and ascertain the nature of
my said Invention, and in what manner the same is to be performed, by an
instrument in writing under my hand and seal, and cause the same to be
inrolled in His Majesty's High Court of Chancery within four calender
months next and immediately after the date of the said Letters Patent,
that then the said Letters Patent, and all liberties and advantages whatsoever
thereby granted, should utterly cease, determine, and become void, anything
herein-before, contained to the contrary thereof in anywise notwithstanding, as
in and by the said Letters Patent (reference being thereunto had) may more
fully and at large appear.
.
NOW KNOW YE, that in compliance with the said proviso, I, the said
David Riz, do hereby describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, in manner following (that is
to say):→
They are made cylindrical and conical, and divided into several partitions or
cisterns, and stand vertical or horizontal under the seat of watercloset, night
table or chair. Those that stand vertical bave their partitions or cisterns at
the side or circumference, and turn in another cylender, and are air and water-
tight, having their proper openings for inlet and outlet. Those that lay
horizontal have their partitions or cisterns at top, turning under a cover, and
have also a moveable or fixed bottom, according to the place it is to be used
and applied, and are also air and water-tight, with their proper inlett and
and outlet. Each partition, division, or cistern of those that lay orizontal
when made use of is turned under the cover, and those that stand
verticle is turned off to another part of the outward cylender. Another
mode of making this apparatus for smaller water chairs, closets, &c., is
that of having one cone to work in another. The outward conc is fized
in the center of a cylender or other figured vessel, which have seperate divi-
sions or cisterns, all of them air and water-tight. At the lower part of the

page_text: inner cone is one opening or outlet, which have a moveable cover or stop.
The outward or fixt cone has as many openings as their are divisions or
cisterns in the cylindrical or other figured vessel used, one other of which is
always opposite to the opening of the inner cone; and when made use of the
contents will naturally drop into such divisions or cisterns when its cover or
stop is removed, and by turning round the said cylender, or other figured vessel
the outward cone is fixed to, the offensive part is removed away, and a clean
cistern brought opposite to the opening of the inner cone, by machinery annexed
to each of the above-described apparatus, composed] either of wheels, racks,
levers, springs, chains, pinions, valves, or sliders, as is best adapted to the place
made use of, and the whole so constructed as to prevent any offensive smell or
vapour transpiring, they admitting of water being poured into each cistern or
partition, or conveyed therein by pipes, or by hydrastatick means and machenery,
either annexed or detached from it; and the primary motion given them is
either by means of lifting and shutting the cover of such watercloset, night
tables, &c., or by pulling of, leavers, wheels, racks, or springs, as may be most
convenient, whereby the same effect is produced.
In witness whereof, I, the said David Riz, have hereunto set my hand
and seal, the Seventh day of September, in the twenty-third year of the
reign of our Sovereign Lord George the Third, by the grace of God of
Great Britain, France, and Ireland King, Defender of the Faith, and
so forth, and in the year of our Lord One thousand seven hundred and
eighty-three.
AND BE IT REMEMBRED, that on the Eleventh of September, in the
year above mentioned, the aforesaid David Riz came before our said Lord the
King in His Chancery, and acknowledged the Specification aforesaid, and
all and every thing therein contained and specified, in the form above written.
And also the Specification aforesaid was stampt according to the tenor of
the Statute in that case made and provided.
