"I, ELLIS LEVER, of the City of Manchester; in the County of Lancaster,
Manufacturer of Colliery Brattice Cloth and. Flexible Tubing, do hereby
declare the nature of the said Invention for "AN IMPROVED MODE OR METHOD
OF FIXING HOOPS IN THE INTERIOR OF FLEXIBLE TUBING EMPLOYED IN THE
VENTILATION OF MINES AND OTHER SIMILAR PURPOSES," to be as follows:-
In the interior of the tubes I place hoops of steel, iron, or wood, at certain
intervals apart, according to the diameter and requirements of the tubing,
and fix the hoops to the tubing by rivets or bolts, by which means I prevent
the breakages which result from the present defective method of stitching
the hoops to the tubes.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ELLIS
LEVER, of the City of Manchester, in the County of Lancaster, Manufacturer
of Colliery Brattice Cloth and Flexible Tubing, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of March, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Ellis Lever, Her special license that I, the said Ellis
Lever, my executors, administrators, and assigns, or such others as I,
the said Ellis Lever, 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 Inven-
tion for "AN IMPROVED MODE OR METHOD OF FIXING HOOPS IN THE INTERIOR OF
FLEXIBLE TUBING EMPLOYED IN THE VENTILATION OF MINES AND OTHER SIMILAR
PURPOSES," upon the condition (amongst others) that I, the said Ellis Lever,
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 Ellis Lever, 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 (that is to say) :-
This Invention relates especially to flexible tubing when employed for
ventilating pit shafts, mines, and other purposes. I place hoops of steel,
wood, or other suitable metal or material at certain distances apart, the said
distances to vary according to the diameter of the tubing or the positions and
places to which it is to be applied. I rivet or bolt these hoops or rings to
the flexible material during the operation of sewing or otherwise seaming
the material to form the tube. And to some of these rivets or bolts I attach

page_text: a ring or partial ring to hang outside the tubing, so that by putting these
rings on nails or pegs driven into the sides of the mine or other convenient
position, or suspended in the shaft by ropes through the rings, the tubing will
be kept in its proper place, and out of danger of damage. And to prevent
damage to the flexible material by the friction of the shoulders of the hooks,
bolts, or rivets, I place a washer of leather or other suitable material between
them.
Having now described the nature and particulars of my said Invention, I
desire it to be understood that I claim, bolting or rivetting hoops to the
flexible tubing with rings or partial rings for the purposes and in the manner
herein described.
In witness whereof, I, the said Ellis Lever, have hereunto set my
hand and seal, this Twenty-fourth day of September, in the year of
our Lord, One thousand eight hundred and sixty-four.
Signed, sealed, and delivered, by
the within-named Ellis Lever,
in the presence of
E. J. HUGHES,
Patent Agent,
Manchester.
ELLIS LEVER. (L.S.)
