Year: 1863

page_text: LETTERS PATENT to Theophilus Alexander Blakely, of Montpelier Square,
in the County of Middlesex, late Captain Royal Artillery, for the Inven-
tion of "IMPROVEMENTS IN METALLIC PACKINGS."
Sealed the 3rd June 1864, and dated the 8th December 1863.
PROVISIONAL SPECIFICATION left by the said Theophilus Alexander
Blakely at the Office of the Commissioners of Patents, with his
Petition, on the 8th December 1863.
I, THEOPHILUS ALEXANDER BLAKELY, of Montpelier Square, in the County
of Middlesex, late Captain Royal Artillery, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN METALLIC PACKINGS," to be as follows:--
My Invention consists in forming metallic packings of a hollow metallic
ring, such as is represented in section at a, Figure 1, or of a corrugated or
lipped plate, such as that represented at b, Figure 2, kept between the
surfaces to be packed, or kept in position by a collar or support. My
packings close the joint to which they are applied, or effect the packing by
their own elasticity; while at the same time the greater the pressure brought
upon them the greater will be their effect.

by the said Theophilus Alexander Blakely in the Great Seal Patent
Office on the 8th June 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THEOPHILUS
ALEXANDER BLAKELY, of Montpelier Square, in the County of Middlesex,
late Captain Royal Artillery, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of December, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Theophilus Alexander Blakely, Her special licence that I,
the said Theophilus Alexander Blakely, my executors, administrators, and
assigns, or such others as I, the said Theophilus Alexander Blakely, 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 METALLIC PACKINGS,"
upon the condition (amongst others) that I, the said Theophilus Alexander
Blakely, my executors or administrators, 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 Theophilus Alexander Blakely, do
hereby declare the nature of my 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, reference being had to the Drawings
hereunto annexed, that is to say:-
My Invention consists in forming metallic packings of a hollow metallic
ring, such as is represented in section at a, Figure 1, or of a corrugated or
lipped plate, such as that represented at 6, Figure 2, kept between the surfaces
to be packed, or kept in position by a collar or support. My packings close
the joint to which they are applied, or effect the packing by their own
elasticity; while at the same time the greater the pressure brought upon them
the
greater will be their effect.
Figure 3 represents a packing in the form of a hollow metallic ring a

page_text: applied at the breech end of the bore of a breech-loading gun; Figure 4
shews a packing in the form of a corrugated or lipped plate 6, also applied to
a breech-loading gun.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, forming metallic packings of a hollow metallic ring, as herein-before
described.
Second, forming metallic packings of a corrugated or lipped plate, as herein-
before described.
In witness whereof, I, the said Theophilus Alexander Blakely, have
hereunto set my hand and seal, this First day of June, One thousand
eight hundred and sixty-four.
T. A. BLAKELY. (Ls.)
