PROVISIONAL SPECIFICATION left by the said John Macintosh and
William Boggett at the Office of the Commissioners, of Patents:
with their Petition, on the 17th January 1872.
We, JOHN MACINTOSH, of Regent's Park, and WILLIAM BOGGETT, of
Chelsea, both in the County of Middlesex, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF HOLLOW
VESSELS OF INDIA-RUBBER APPLICABLE TO THE MANUFACTURE OF AIR AND WATER
BEDS OR CUSHIONS AND ARTICLES FOR APPLYING HEAT AND COLD AND FOR PROTECTION

page_text: AVALON DURAR RAID, DUCH AXULLO W VESSELS BEING ALSO APPLICABLE AS DRESS IM-
PROVERS OR FOR HOLDING LIQUIDS FOR DRINKING AND OTHER PURPOSES," to be as
follows:-
The object of this Invention is,—
Firstly. To prepare hollow vessels of a globular or other suitable shape
composed of india-rubber (expanded as described in the Specification of
a Patent granted to us and dated 6th May 1871, No. 1226), such hollow
vessels being enclosed in lengths of clastic tubular fabric, and filled or
distended with air or water. These lengths we convert into beds or
cushions by interweaving or otherwise sometimes connecting the vessels
in each length together, so that they can all be filled or emptied through
a single valve.
Secondly. Our Invention relates to the adaptation and use of similar
vessels inflated with air, which being a non-conductor of heat affords
great protection to the head from the rays of the sun. The vessels we
prefer for this purpose to apply on the exterior of hats or other head
gear consist of expanded tubes encased in light textile materials, and for
the interior a circular vessel shaped like a flattened globe, constructed
by cementing (with dissolved rubber) the middle of the two pieces of
sheet rubber of which the vessel is to be made, so that when inflated
the circumference only expands, the centre being held together by the
cement.
A like arrangement is very useful in constructing beds or cushions by
converting two sheets of rubber into a bag, previously spotted or streaked
on the inside at intervals with cement in order to divide it into chambers
or compartments, which method has the advantage of allowing a covering
of elastic web being securely affixed thereto by metal eyelets passing
through the bag at the cemented parts, which prevents the escape of air
after the bag is inflated.
Thirdly. Our Invention relates to the adaptation and use of vessels of
a like description as improvers of ladies' dresses, commonly called
bustles, such vessels being made of inflated rubber in shapes suitable for
the intended purpose.
Fourthly. Our Invention relates to the adaptation and use of similar
vessels or tubes (protected by elastic webbing and filled with hot water) {
as a means of applying heat to the human body, warming beds, or
applying heat for other purposes.

Also for applying cold when such tubes or vessels are filled with ice.
Such tubes or vessels may also be adapted and used according to our
Invention for containing liquids for drinking and other purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Macintosh and William Boggett in the
Great Seal Patent Office on the 17th July 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
MACINTOSH, of Regent's Park, and WILLIAM BOGGETT, of Chelsea, both
in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of January, in the
year of our Lord One thousand eight hundred and seventy-two, in
the thirty-fifth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Macintosh and William
Boggett, Her special licence that we, the said John Macintosh and
William Boggett, our executors, administrators, and assigns, or such
others as we, the said John Macintosh William Boggett, our execu-
tors, 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 THE CONSTRUCTION OF HOLLOW VESSELS OF INDIA-RUBBER APPLICABLE TO THE
MANUFACTURE OF AIR AND WATER BEDS OR CUSHIONS AND ARTICLES FOR APPLYING
HEAT AND COLD AND FOR PROTECTION AGAINST SOLAR RAYS, SUCH HOLLOW VESSELS
BEING ALSO APPLICABLE AS DRESS IMPROVERS OR FOR HOLDING LIQUIDS FOR DRINKING
AND OTHER PURPOSES," upon the condition (amongst others) that we, the
said John Macintosh and William Boggett, our executors or adminis-
trators, by an instrument in writing under our or their hands and seals,
or under the hand and seal of one of us or them, should particularly
describe and ascertain the nature of the said Invention, and in what

after the bag is inflated.
Thirdly. Our Invention relates to the adaptation and use of vessels
of a like description as improvers of ladies' dresses, commonly called

the intended purposes.
Fourthly. Our Invention relates to the adaptation and use of similar

or for applying heat for other purposes.
Also for applying cold when such tubes or vessels are filled with ice.
Such tubes or vessels may also be adapted and used according to our
Invention for containing liquids for drinking and other purposes.
The efficiency, cheapness, portability, and lightness of such vessels
renders them especially suitable for the above-named purposes.
In witness whereof, we, the said John Macintosh and William
Boggett, have hereunto set our hands and seals, this Fifteenth
day of July, in the year of our Lord One thousand eight hundred
and seventy-two.
