Year: 1870

page_text: LETTERS PATENT to George Spencer, Civil Engineer, of No. 77,
Cannon Street, London, for the Invention of "IMPROVED METHODS OF
FORMING PATTERNS ON THE SURFACE OF KAMPTULICON OR OTHER SIMILAR
SUBSTANCES USED FOR FLOOR COVERINGS AND MATS."
Sealed the Sth October 1870, and dated the 14th April 1870.
PROVISIONAL SPECIFICATION left by the said George Spencer at the
Office of the Commissioners of Patents, with his Petition, on the
14th April 1870.
I, GEORGE SPEncer, Civil Engineer, of No. 77, Cannon Street, London,
do hereby declare the nature of the said Invention for "IMPROVED METHODS
OF FORMING PATTERNS ON THE SURFACE OF KAMPTULICON OR OTHER SIMILAR
SUBSTANCES USED FOR FLOOR COVERINGS AND MATS," to be as follows:-
My improvements in floor covering and mats consist in,―
1st. In a method or methods by which the pattern usually printed or
formed on the surface of kamptulicon, linoleum, or other similar cloth or
materials used for floor coverings and mats is printed or formed in recesses

page_text: sunk in the surface of the material in such manner that the substance
of the pattern is below or level with the surface to be trodden on.
In order to effect this object I form a suitable raised pattern on the
cylinder of a roller press, then pass the kamptulicon or other cloth
through the press, by which operation it receives a sunken pattern, on
the surface of which the pattern is to be printed or formed, or the sunken
pattern may be left plain if desired.
Or I form the pattern to be sunk in the kamptulicon or other cloth or
substance-in-or-on-a-flat-plate-or-surface,-and-laying-such-on-or-under-
the kamptulicon or other cloth or substance pass both under a roller
press, by which means a sunken surface or surfaces will be formed on
which the pattern may be printed or formed, or left without color if
preferred.
Or I form the raised pattern on a flat plate and by means of a press
actuated by hydraulic, steam, screw, or other suitable power by means 1
of such plate impress the sunken surface or surfaces intended to receive
the pattern on the kamptulicon or other cloth or substance, or the pattern
so made may be left plain..
Or I sometimes form the plate used for impressing the sunken surfaces
in separate pieces which can be put together to form the entire pattern, 2
by which means the width of the cloth can be varied and expense saved
in forming the pattern.
The pattern plates for forming the sunken surfaces can be made of
any suitable material, such as cast or wrought iron or other metal or
mixture of metals, or of wood, and they can be used to impress the pattern 2
either over or under the cloth, or the pattern plates may be perforated to
form the pattern.
Or I first print or form or emboss the pattern on the cloth, and by
either of the methods described above sink the pattern into the cloth.
In all the methods I prefer to warm the kamptulicon or other similar 3
material by placing it in a heating chamber, or by placing it in a surface
heated by steam or other suitable means.

filed by the said George Spencer in the Great Seal Patent Office
on the 13th October 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
SPENCER, Civil Engineer, of No. 77, Cannon Street, London, send
greeting.
WHEREAS IIer most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of April, in the year of
our Lord One thousand cight hundred and seventy, in the thirty-
third year of Her reign, did, for Ierself, Her heirs and successors,
give and grant unto me, the said George Spencer, Her special licence
that I, the said George Spencer, my executors, administrators, and
assigns, or such others as I, the said George Spencer, 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 "IMPROVED METHODS
OF FORNING PATTERNS ON THE SURFACE OF KAMPTULICON OR OTHER SIMILAR
SUBSTANCES USED FOR FLOOR COVERINGS AND MATS," upon the condition
(amongst others) that I, the said George Spencer, my executors or ad-
ministrators, 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 George Spencer, 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:-
My improvements in floor coverings and mats consist in,-
1st. In a method or methods by which the pattern usually printed
or formed on the surface of kamptulicon, linoleum, or other similar
cloth or materials used for floor coverings and mats, is printed or formed
in recesses sunk in the surface of the material in such manner that the
substance of the pattern is below or level with the surface to be
trodden on.

cylinder of a roller press, then pass the kamptulicon or other cloth
through the press, by which operation it receives a sunken pattern, on
the surface of which the pattern is to be printed or formed, or the sunken
pattern may be left plain if desired.
Or I form the pattern to be sunk in the kamptulicon or other cloth
in or on a flat plate or surface, and laying such on or under the
kamptulicon or other cloth pass both under a roller press, by which
means a sunken surface.or surfaces-will-be-formed,-on-which-tho-pattern-
may be printed or formed or left without colour if preferred.
Or I form the raised pattern on a flat plate and by means of a press
actuated by hydraulic, steam, screw, or other suitable power by means
of such plate impress the sunken surface or surfaces intended to receive
the pattern on the kamptulicon or other cloth or substance, or the
pattern so made may be left plain.
Or I sometimes form the plate used for impressing the sunken surfaces

materials by placing it in a heating chamber or by placing it on a surface
heated by steam or other suitable means.
In witness whereof I, the said George Spencer have hereunto set
my hand and seal, this Thirteenth day of October, in the year
of our Lord One thousand eight hundred and seventy.
