TO ALL TO WHOM THESE PRESENTS SHALL COME, I
JOHN CHATTERTON, of Birmingham, in the County of Warwick, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of April, in the year
of our Lord One thousand eight hundred and fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Chatterton, Her special licence
that I, the said John Chatterton, my executors, administrators, and
assigns, or such others as I, the said John Chatterton, 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 "IMPROVEMENTS IN
COATING TUBES," upon the condition (amongst others) that I, the said
Jolin Chatterton, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said In-
vention, 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 John Chatterton, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement thereof (that is to say):
This Invention consists of coating a tube composed of gutta percha,
india-rubber, or compounds containing such materials, with lead or soft
metal, by drawing the metal on to tubes of the softer material.
Having thus stated the nature of my said Invention, I will now
describe the manner of performing the same. The leaden or other soft
metal tube is to be made in the ordinary manner, and internally some-

page_text: what larger than the tube of gutta percha, india-rubber, or compounds
containing such matter or matters, so that the lead or soft metal tube
may be readily passed over the other material or materials. The lead
or soft metal tube, with the tube of gutta percha, india-rubber, or
composition within it, is next to be drawn through a die, or passed
between grooved rollers suitable for reducing the diameter of the lead
or soft metal tube to such a diameter as closely to fit the exterior of
the tube within it. By these means, tubes of gutta percha, india-
rubber, or composition, will be coated and protected by lead or other
soft metal, and will offer a new manufacture of tubes applicable to
various purposes.
In witness whereof, I, the said John Chatterton, have hereunto
set my hand and seal, this Twelfth day of October, in the
year of our Lord One thousand eight hundred and fifty-three.
Witness, B. GOBEY,
JOHN CHATTERTON. (L.s.)
