Year: 1805

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Sir GEORGE
WRIGHT, of Ray Lodge, in the County of Essex, Baronet, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date the
Thirtieth day of March, in the forty-fifth year of His said Majesty's reign,
did give and grant unto me, the said Sir George Wright, His special licence,
full power, sole privilege and authority, that I, the said Sir George Wright,
my executors, administrators, and assigns, should and lawfully might, during
the term of years therein expressed, make, use, exercise, and vend, through-
out that part of His Majesty's United Kingdom of Great Britain and Ireland
called England, His Majesty's Dominion of Wales, and Town of Berwick-
upon-Tweed, my Invention (that is to say), "AN INSTRUMENT OR MACHINE FOR
CUTTING OUT OF SOLID STONE, WOOD, OR OTHER MATERIALS, PILLARS OR TUBES, EITHER
CYLINDRICAL OR CONICAL, WITH GREAT SAVING OF LABOUR AND MATERIALS;" in
which said recited Letters Patent is contained a proviso obliging me, the said Sir
George Wright, by writing under my hand and soal, to cause a particular
description of the nature of my said Invention, and in what manner the
same is to be performed, to be inrolled 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 said recited Letters Patent, and the Stattue
in that behalf made, relation being thereunto bad, may more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, and in pursu-
ance of the said Stature, I, the said Sir George Wright, do hereby declare
that my said Invention, (that is to say,) an Instrument or Machine for Cutting
out of Solid Stone, Wood, or other Materials, Pillars or Tubes either Cylin-
drical or Conical, with great Saving of Labor and Materials, is described and
ascertained in manner and form following (that is to say) :-
The intention and end of the Invention which is the object of this Patent
is to form or cut stone, wood, or other materials into divers tubes or columns
of various diameters, and various other circular work, without the labor and
expence of chipping or hollowing, and also by means thereof to form pipes,
cisterns, cantelavres, chimney tops, arches, arches for sewers, gothic_work,
semicircles, ovals, connection of circles, or ovals with inverted curvatures, and
all other circular work.
This Invention is the application of a saw or saws, or other instruments, in
a hole or holes previously drilled in the stone, wood, or other materials for
that purpose, or of saws or instruments for sawing, working, or cutting
from a centre or centres, or in a tangent of any given circle or oval.
The Plan or Plate in the margin marked A exhibits a block of stone, wood,
or other materials, and drill for drilling holes therein. In the first place a
hole or holes is or are drilled through the block for a centre or for centres
whence the saw is to work, and which hole or holes may be drilled by any
other species of drill whatsoever, and other holes in like manner are to be
drilled at given distances according to the diameter of the tubes or columns
or other work required to be performed, which holes are to be perforated pre-
paratory to the use or application of the saw, saws, or instruments herein-after
described.
The Plans or Plates in the margin marked B, C, D, exhibit saws or instru-
ments for working in stone, wood, or other materials, acting on the principle
of working in a hole or holes previously drilled therein.
The Plan or Plate in the margin marked B exhibits a saw or instrument
applied to form the tube or column required, and the manner in which the
same acts or performs the work.
The Plan or Plate in the margin marked (C) exhibits a saw or instrument
by which connective sigments of circles are formed from centres which are
out of the block of stone, wood, or other materials.
The aforesaid Plans or Plates in the margin marked B, C, exhibit two of
the modes by which the saws or instruments are connected with their centres
acting upon one and the same principle, though the assistance of the drill is
not required in the Plan or Plate in the margin marked (C).

page_text: The Plan or Plate in the margin marked D exhibits a saw or instrument
acting between circles or grooves fixed at each end of a block of stone, wood,
or other materials, without any direct connection with the centre, or drilling
any centre hole.
The Plans or Plates in the margin exhibit some of the modes, ways, or
means by which this Invention may be carried into effect, but other instru-
ments may be made or employed or used to the same effect, and on the same
principles.
In witness whereof, I, the said Sir George Wright, have hereunto set my
hand and seal, the Thirtieth day of April, in the forty-fifth year of the
reign of our Sovereign Lord George the Third, by the grace of God
of the United Kingdom of Great Britain and Ireland King, Defender
of the Faith, and in the year of our Lord One thousand eight hundred
and and five.
