Patent, bearing date the Thirteenth day of September, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Sampson Hanbury, Her special license that I, the said Sampson Hanbury,
my executors, administrators, and assigns, or such others as I, the said Sampson
Hanbury, my 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 "AN IMPROVEMENT IN THE MANU-
FACTURE OF TUBES OF COPPER, BRASS, AND OTHER METALS," upon the condition
(amongst others) that I, the said Sampson Hanbury, my executors, or admi-
nistrators, by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same 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 Sampson Hanbury, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawing hereunto annexed, that
is to say:-
My Invention consists in constructing tubes thicker at both ends than in the
centre or general body of the tubes in order to afford facility for fixing them.
This method of constructing tubes will be found of great advantage where
light tubes are desired.
In the annexed Drawing, which is a longitudinal section of a tube, the
same external diameter is preserved throughout, the thickening of the ends
of the tube being in the interior. I do not, however, confine myself to
forming the thickening in the inside, but I claim the construction of tubes
with both ends thicker than the centre or general body thereof.
In witness whereof, I, the said Sampson Hanbury, have hereunto set
my hand and seal, this Eleventh day of March, One thousand eight
hundred and fifty-nine.
SAMPSON HANBURY.
