IMPROVEMENTS IN THE MANUFACTURE OF MOPS OR "SPONGES" FOR CLEANSING CANNON
Year: 1860

page_text: LETTERS PATENT to Frederick William Mart, of 11, Gresham Street
West, E.C., for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
MOPS OR "SPONGES" FOR CLEANSING CANNON."
Sealed the 31st July 1860, and dated the 20th February 1860.
PROVISIONAL SPECIFICATION left by the said Frederick William Mart
at the Office of the Commissioners of Patents, with his Petition, on the
20th February 1860.
I, FREDERICK WILLIAM MART, of 11, Gresham Street West, E.C., do
5 hereby declare the nature of the Invention for "IMPROVEMENTS IN THE MANU-
FACTURE OF MOPS OR SPONGES' FOR CLEANSING CANNON," to be as follows:-
This Invention has for its object improvements in the manufacture of mops
or "sponges" for cleansing cannon. For these purposes it is preferred to
employ vegetable fibres woven and made up as hereafter explained, at the
O same time wool or other animal fibre may be similarly woven and made up
into mops or "sponges." The back of the fabric is when vegetable fibre is
employed, by preference of strong yarns of flax or hemp, which yarns compose
the warp of the woven back fabric, it being wefted by similar yarns, and on
the face of such fabric intermediate of the two ends of a piece which is to be

page_text: used in making a mop or "sponge," a strong cut pile is produced, by pre-
ference of strong fibres of hemp, the pile being formed to the length desired,
and such cut pile is produced in like manner to that in which piled rugs and
mats have heretofore been produced; the pile, however, only extending to a
portion of the length of the piece of fabric suitable for a mop or "sponge,"
the back fabric extending as before mentioned beyond both ends of the pile.
The two edges or selvages of the fabric are sewed together so as to form it
into a tube, the pile being outwards, and one projecting end of the back
fabric is folded over and sewed so as to receive a draw.string or cord, and the
other projecting portion of the weaving is folded in at the end so as to close it.
The head or end of the stave or handle is introduced into the tube, and then
the draw string or cord is drawn tightly, so as to close that end securely on to
the stave or handle just beyond the larger end or head.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick William Mart in the Great Seal Patent Office
on the 20th August 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
WILLIAM MART, of 11, Gresham Street West, E.C., send greeting.
WHEREAS IIer most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of February, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her. reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Frederick William Mart, Her special licence that I, the said Frederick
William Mart, my executors, administrators, and assigns, or such others as
1, the said Frederick William Mart, 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 MOPS OR 'SPONGES
CANNON," upon the condition (amongst others) that I, the said Frederick
William Mart, 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

page_text: Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Frederick William Mart, 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 :-
This Invention has for its object improvements in the manufacture of mops
or sponges for cleansing cannon. For these purposes it is preferred to employ
vegetable fibres woven and made up as hereafter explained, at the same time
wool or other animal fibre may be similarly woven and made up into mops or
sponges. The back of the fabric is when vegetable fibre is employed, by
preference, of strong yarns of flax or hemp, which yarns compose the warp of
the woven back fabric, it being wefted by similar yarns. And on the face of
such fabric, intermediate of the two ends of a piece which is to be used in
making a mop or sponge, a strong cut pile is produced, by preference, of strong
fibres of hemp, the pile being formed to the length desired, and such cut pile
is produced in like manner to that in which piled rugs and mats have here-
tofore been produced; the pile, however, only extending to a portion of the
length of the piece of fabric suitable for a mop or sponge, the back fabric
extending as before mentioned beyond both ends of the pile. The two edges
or selvages of the fabric are sewed together so as to form it into a tube, the
pile being outwards, and one projecting end of this back fabric is folded over
and sewed so as to receive a draw string or cord, and the other projecting
portion of the weaving is folded in at the end so as to close it. The head or
end of the stave or handle is introduced into the tube, and then the draw
string or cord is drawn tightly so as to close that end securely on to the stave
or handle just beyond the larger end or head.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows plan and section of a piece of cloth woven in a suitable
form for a coating for the head or enlarged end of the stave or handle. The
two ends a and b of this fabric are woven without any pile, whilst the inter-
mediate part c thereof is woven with pile. In making this woven fabric into
a suitable form for a coating to the head or end of the stave or handle, the
two edges of the woven fabric are to be sewed together, one of the ends
(say b) is to have a draw string applied, and the other end (say a) is to be
closed in so as to cover the end or head of the handle.
Figure 2 shows the

page_text: I would state that I do not claim generally the weaving of fabrics partly
plain and partly with pile; but what I claim in the manufacture of mops or
sponges " for cleansing cannon is, the application of pile fabrics woven and
made up as herein described as coatings for the enlarged ends or heads of the
staves or handles.
In witness whereof, I, the said Frederick William Mart, have hereunto
set my hand and seal, this Twentieth day of August, in the year of our
Lord One thousand eight hundred and sixty.
FREDERICK WILLIAM MART. (L.S.)
