Year: 1857

page_text: LETTERS PATENT to Caleb Tayler, of Deptford, in the County of Kent,
Gentleman, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
SHEETS OF MATERIAL SUITABLE FOR COVERING FLOORS, AND FOR OTHER USEFUL
Dunone".
Sealed the 31st July 1857, and dated the 8th May 1857.
PROVISIONAL SPECIFICATION left by the said Caleb Tayler at the
Office of the Commissioners of Patents, with his Petition, on the.
8th May 1857.
I, CALEB TAYLER, of Deptford, in the County of Kent, Gentleman, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE
OF SHEETS OF MATERIAL SUITABLE FOR COVERING FLOORS, AND FOR OTHER USEFUL
PURPOSES," to be as follows:-
My said Invention consists in the combination of caoutchouc, gutta percha,
and jinta wan, in variable proportions, by means customarily practised, and
incorporating therewith cork, tanners' waste bark, the residue from manu-
facturing cocoa-nut fibre, and ordinary sawdust, free or freed from resin, with
other suitable species of bark, pith, and wood, in a minute state of division;
and in manufacturing such compound material into sheets, by the machinery
usually employed, to any required thickness.
The combined gums are masticated, alone or along with waste vulcanized
india-rubber, the several vegetable matters in powder or like sawdust,
occasionally adding, as required for different articles, sulphur, pyrites, silicate.
of magnesia, retort residium, and other similar oxides and earths.
Sheets of the material from any of these mixtures may be extended to the
needful size by seaming them as commonly practised.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CALEB
TAYLER, of Deptford, in the County of Kent, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of May, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Caleb Tayler, Her special licence that I, the said Caleb Tayler, my
executors, administrators; and assigns, or such others as I, the said Caleb
Tayler, 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
THE MANUFACTURE OF SHEETS OF MATERIAL SUITABLE FOR COVERING FLOORS, AND
FOR OTHER USEFUL PURPOSES," upon the condition (amongst others) that I,
the said Caleb Tayler, 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 the said Caleb Tayler, 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: -
My said Invention consists, first, in the combination of caoutchouc, gutta
percha, and jinta wan, in variable proportions, by means customarily practised,
and incorporating therewith certain vegetable matters, either in a fibrous or
in a divided state like sawdust, adding particular mineral and colouring
ingredients, when desired.
And, second, in manufacturing such compound material into sheets by the
application of machinery usually employed, making the same to any required
thickness.
And for the better understanding of my said improvements, I will now
proceed to detail my method of carrying the same into practical operation.

page_text: The several gums are to be combined by mastication, either alone or along
with waste vulcanized india-rubber; and the material thus obtained must be
incorporated with cork, tanners' waste bark, the residue from manufacturing
cocoa-nut fibre, ground refuse leather, refuse from flax and cotton mills, papier
mache, and ordinary sawdust, free or freed from resin, with other suitable
species of bark, pith, fibre, and wood, in a minute state of division. Occa-
sionally may be added, as required for different articles, sulphur, pyrites,
silicate of magnesia, retort residium; also the sulphites or hyposulphite of
lead or zinc (either in the state of powder or vapour); likewise natural or
artificial sulphurets, kermes mineral, sulphuret of antimony, alumn, chalk or
lime, with other similar oxides, salts, and earths,
The combined gums alone, or the same combined with any of the before-
named matters, may be masticated with the usual colouring materials, pro-
ducing masses of black, green, brown, red, and other colours; which masses in
various forms and quantity may be worked together and pressed into one
mass, which, when cut or pressed into sheets, will afford veined or marbled
patterns.
I employ in all my operations the usual machinery for masticating, incorpo-
rating, pressing, rolling, and cutting the material. And by means of the same,
my said compositions are rolled into sheets, which may be extended to any
needful size by seaming, or other means in common use, thereby rendering
sheets of the material available for covering floors, roofs, walls, and like
applications; and for which they may be sometimes rendered more suitable
by varnishing or painting one or both sides.
Having thus fully described my said Invention, I wish it to be understood,
that I do not limit myself to sheets of any particular dimensions, or mode of
fastening one sheet to another, or to any precise description of machinery; but
what I do claim as my Invention is, namely:-
The peculiar compositions for manufacturing sheets of waterproof material
for covering floors, and for other useful purposes, as described.
In witness whereof, I, the said Caleb Tayler, have hereunto set my
hand and seal, this Fourth day of November, in the year of our Lord
CALEB TAYLER. (L.S.)
