Year: 1817

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
FREDERICK Marquis de CIABANNES, of Drury Lane, in the County of Middle-
sex, send greeting.
WHEREAS His present 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 Nineteenth
day of December, in the fifty-eighth year of His reign, give and grant unto
me, the said Jean Frederick Marquis de Chabannes, my executors, admini-
strators, and assigns, His especial licence, full power, sole privilege and
authority, that I, the said Jean Frederick Marquis de Chabannes, my 'execu-
tors, administrators, and assigns, during the term of years therein expressed,
should and lawfully might make, use, excrcise, and vend my "NEW METHOD
OF CONSTRUCTING PIPES OR TUBES OF COPPER, SHEET LEAD, SHEET IRON, TIN, OR
OTHER METALS OR MIXTURE OF METALS CAPABLE OF BEING REDUCED INTO SHEETS,"
within England, Wales, and the Town of Berwick-upon-Tweed, in such
manner as to me, the said Jean Frederick Marquis de Chabannes, my execu-
tors, administrators, and assigns, should in our discretion seem meet; in which
said Letters Patent is contained a proviso that if I, the said Jean Frederick
Marquis de Chabannes,, should not particularly describe and ascertain the
nature, of my said Invention, and in what manner the same is to be per-

page_text: formed, 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 two
calendar 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,
as in and by the said recited Letters Patent, relation being thereunto had,
may more fully and at large appear.
NOW KNOW YE,. that in compliance with the said proviso, I, the said
Jean Frederick Marquis de Chabannes, do hereby declare that the nature
of my said Invention, and in what manner the same is to be performed,
are particularly described and ascertained in the Drawing hereunto annexed,
and the following description thereof and references thereto (that is to
say):-
The object of my Invention is to turn the seams of pipes or tubes of copper,
sheet lead, sheet iron, tin, or other metals or mixture of metals capable of
being reduced into sheets, either by employing a cylinder, lever press and
wedge, or otherwise.
The annexed Drawing will sufficiently explain the Invention, and the
principle on which it acts. Figure 1, plan of a machine; A, the the cylinder,
on which is affixed a band of steel B, in the form of a screw; C, a plate of
steel affixed on the bed D, one eighth of an inch in thickness, with the bottom
edge bevelled off; E, E, the levers on which the cylinder has its axis, and
.working on the centre at F; G, a screw, by means of which you keep down
your sheet of iron or other metal on the plate D, and by one revolution of
the cylinder the first return of your seam is made, as is seen in Figure 5,
and by bringing down the cylinder under the centre you finish the return of
your seam, as in Figure 6; Figure 2, front view of the machine; Figure 3,
section of the same; Figure 4, outside of end, shewing the manner by which
the foot lever H acts; Figures 7 and 8, two cylinders to be used for turning
and closing the seam. I give this as one method by which the end may be
obtained, but it will be sufficiently obvious to a workman that the same object
may be effected by the different means above stated. The letters of reference
answer to the same parts in the several Figures.
In witness whereof, I, the said Jean Frederick Marquis de Chabannes,
have hereunto set my hand and seal, this Nineteenth day of February,
in the year of our Lord One thousand eight hundred and eighteen.
CHABANNES. (L.S.)
