page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ANTHONY
GEORGE ECKHARDT, of Berwick Street, Golden Square, in the County of
Middlesex, Gentleman, and Member of the Royal Society of London, and of
the Society of Haarlau in Holland; and JOSEPH LYON, of Millbank Street,
Westminster, in the said County Middlesex, Cooper, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Royal Letters Patent under the Great Seal of the United Kingdom of
Great Britain and Ireland, bearing date at Westminster, the Eighteenth
day of December, in the forty-seventh year of His reign, give and grant unto
us, the said Anthony George Eckhardt and Joseph Lyon, our executors,
administrators, and assigns, His especial licence that we, the said Anthony
George Eckhardt and Joseph Lyon, our exccutors, administrators, and assigns,
during the the term of years therein mentioned, should and lawfully may make,
use, exercise, and vend our said Invention of an "IMPROVEMENT ON, AND A NEW
METHOD OF, MANUFACTURING PIPES FOR THE CONVEYANCE OF WATER UNDER GROUND,"
within that part of the United Kingdom of Great Britain and Ireland called
England, Wales, and the Town of Berwick-upon-Tweed; in which said
Letters Patent there is contained a proviso obliging us, the said Anthony
George Eckhardt and Joseph Lyon, or one of us, by an instrument-in writing

page_text: under our hands and seals, or under the hand and scal of one of us, to cause
a particular description of the nature of our said Invention, and in what
manner the same is to be performed, to be enrolled in His Majesty's High
Court of Chancery within one calendar month next after the date of the
said recited Letters Patent, as in and by the same, relation being thereunto
had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
Anthony George Eckhardt and Joseph Lyon, do hereby declare that our said
Invention, and the manner in which the same is to be carried into effect and
practice, are described in manner following (that is to say) :-
Instead of perforating the trunk of a tree, or any solid piece of wood, as is
usually done in the fabrication of pipes for the conveyance of water, we do
form each and every of our pipes of different pieces or staves, resembling the
staves of a barrel, but of less curvature and of greater proportional length, and
we do fashion the said staves of our pipes either by hand or (in preference) by
such fit and appropriate machinery as among the tools, implements, and
machines of well-known construction and use may be best suited for that
purpose in such a manner as that the said staves shall fit cach other, and
include a cylindrical or icarly cylindrical bore or cavity, and that the external
surfaces thereof shall form a conical or long spheroidal or otherwise tapering
figure, properly suited for driving a sufficient number of strong hoops of metal
or other fit material thereon, for the purpose of giving firmness and strength to
the whole, and of rendering the same water-tight; or otherwise we do close the
said staves together by driving wedges under the said hoops, or by screwing the
.said hoops together, and in these or the like cases the external surfaces of the
said pipes may be cylindrical or of any other convenient figure. And further,
we do taper by the turning lathe, or otherwise, such of the extremities of our
said pipes as are intended to be fitted by insertion into other lengths or pieces
of the said pipes; and we do also excavate and enlarge a correspondent small
part of the bore of such other lengths or pieces of our said pipes as arc or may
be intended to receive the said tapering extremities. And morcover we do, in
all cases wherein the same may be thought needful, connect and close our said
staves together by the methods of dovetailing, or tongueing, or rabitting, or by
means of screws, or by any other of the known and approved methods of
joining the surfaces of wood together; and we do paint or cover the inner or
outer surfaces, or the surfaces within the joints, or all or any of them, with
pitch, tar, varnish, cement, or other suitable matters, to preserve the said
pipes, and to render them more effectually water-tight. And lastly, we do
make use of all kinds of wood, or other materials whatsoever, which are or

page_text: may be proper for the construction of our said pipes, as herein-before described
and set forth.
In witness whereof, we, the said Anthony George Eckhardt and Joseph
Lyon, have hereunto set our hands and seals, this Fifteenth day of
January, in the year of our Lord One thousand eight hundred and
seven.
