at the Office of the Commissioners of Patents, with his Petition, on the
11th May 1865.
I, THOMAS JEFFERSON MAYALL, of Roxbury, Massachusetts, in the United
States of America, but now residing at Red Lion Court, Fleet Street, in
the City of London, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF HOSE AND OTHER FLEXIBLE TUBING,
WHICH IMPROVEMENTS ARE ALSO APPLICABLE IN UNITING SURFACES OF INDIA-RUBBER
GUTTA PERCHA, OR OF COMPOUNDS THEREOF TO EACH OTHER. OR TO WOVEN OR OTHER.
FABRIC OR MATERIAL FOR OTHER PURPOSES," to be as follows:-
In the manufacture of hose or other flexible tubing I take india-rubber or
gutta percha, or a compound thereof, in sheets with which sulphur has been
combined for the purpose of its conversion or vulcanization; but previous to

page_text: such conversion or vulcanization I apply to one surface thereof a layer of
cement, hereafter more fully referred to; and when a layer of such cement
has been applied to such sheet, india-tubber, gutta percha, or a compound
thereof, I subject such sheet to the action of heat in the usual manner to
effect the conversion or vulcanization thereof. When conversion or vulcani-
zation is complete I cut such sheets into breadths adapted to the size of hose
or other tubing desired to be obtained, and I apply to the surface thereof to
which the cement was previously applied a corresponding width of strong
woven or other fabric or material, the surface of which (so applied to the
surface of india-rubber, gutta percha, or compound thereof) has previously
received a coating of the cement referred to. I then press together the two
surfaces by means of rollers or otherwise by which the complete union thereof
will be effected. Hose or other tubing is then formed by sewing, or rivetting,
or otherwise connecting together the edges of such strips or breadths. The
cement above referred to is obtained by mixing shellac with india-rubber,
gutta percha, or a compound thereof, dissolved by camphine or other suitable
solvent; and I prefer to combine these matters in the following proportions,
say, 8 lbs. of india-rubber, gutta percha, or a compound thereof, ground with
2 lbs. of pure gum shellac, and then dissolved in highly rectified camphine
in quantity adapted to the degree of consistency desired to be obtained, but
I do not confine myself to these proportions. To obtain increased strength
to such hose or other tubing several layers or thicknesses of the woven or
other fabric or material may be laid one on the other, and united together
by the aid of the cement referred to. When woven or other fabric or
material is desired to be applied to both surfaces of the india-rubber, gutta
percha, or compound thereof, both of such surfaces will be treated as I have
explained in relation to one of them.
The processes referred to are also applicable in uniting surfaces of india-
rubber, gutta percha, or compounds thereof, to each other, or to woven or
other fabric or material for other purposes
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Jefferson Mayall in the Great Seal Patent Office
on the 9th November 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I THOMAS
JEFFERSON MAYALL, of Roxbury, Massachusetts, in the United States of
America, but now residing at Red Lion Court, Fleet Street, in the City of
London, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of May, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Jefferson Mayall, Her special licence that I, the said
Thomas Jefferson Mayall, my executors, administrators, and assigns, or
such others as I, the said Thomas Jefferson Mayall, my executors, adminis-
trators, 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 night make, use, exercise, and vend, within the United King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF HOSE AND OTHER
FLEXIBLE TUBING, WHICH IMPROVEMENTS ARE ALSO APPLICABLE IN UNITING SURFACES
OF INDIA-RUBBER, GUTTA PERCHA, OR OF COMPOUNDS THEREOF TO EACH OTHER, OR TO
WOVEN OR OTHER FABRIC OR MATERIAL FOR OTHER PURPOSES," upon the condition
(amongst others) that I, the said Thomas Jefferson Mayall, 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 Thomas Jefferson Mayall, 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 :-
In the manufacture of hose or other flexible tubing, I take sheet india-
rubber or gutta percha, or a compound thereof, with which sulphur has been
combined for the purpose of its conversion or vulcanization; but previous to
such conversion or vulcanization I apply to one surface thereof a layer of
cement hereafter more fully referred to; and when a layer of such cement
has been applied to such sheet india-rubber, gutta percha, or a compound
thereof, I subject such heat to the action of heat in the usual manner to
effect its conversion or vulcanization. When conversion or vulcanization is
complete I cut such sheets into breadths adapted to the size of hose or other
tubing desired to be obtained, and I apply to the surface of such breadth to
which the cement was previously applied a corresponding width of strong
woven or other fabric or material, the surface of which (so applied to the
surface of india-rubber, gutta percha, or compound thereof) has previously

page_text: received a coating of the cement referred to. I then press together the two
surfaces by means of rollers or otherwise by which the complete union thereof
will be effected. Hose or other tubing is then formed by sewing, or rivetting,
or otherwise connecting together the edges of such strips or breadths. The
cement above referred to is obtained by mixing shellac with india-rubber,
gutta percha,or a compound thereof, dissolved by camphine or other suitable
solvent; and I prefer to combine these matters in the following proportions,
say, 8 lbs. of india-rubber, gutta percha, or a compound thereof, ground with
2 lbs. of pure gum shellac, and then dissolved in highly rectified camphine
in quantity adapted to the degree of consistency desired to be obtained, but I
do not confine myself to these proportions. To obtain increased strength to
such hose or other tubing, several layers or thicknesses of the woven or other
fabric or material may be laid one on the other and united together by the
aid of the cement referred to. When woven or other fabric or material is
desired to be applied to both surfaces of the india-rubber, gutta percha, or
compound thereof, both of such surfaces may be treated as I have explained
in relation to one of them.
The pro
to are also applicable in uniting surfaces of india-
rubber, gutta percha, or compounds thereof, to each other, or to woven or
other fabric or material for other purposes.
In witness whereof, I, the said Thomas Jefferson Mayall, have hereunto
set my hand and seal, this Eighth day of November, in the year of our
Lord One thousand eight hundred and sixty-five.
THOS, J. MAYALL. (L.8.)
