AN IMPROVED MODE OF PACKING PRESERVED MEATS AND FRUITS FOR SALE
Year: 1868

page_text: LETTERS PATENT to Timothy Coleman Blanchflower, of Great
Yarmouth, in the County of Norfolk, Bloater Paste Manufacturer,
for the Invention of "AN IMPROVED MODE OF PACKING PRESERVED MEATS
AND FRUITS FOR SALE."
PROVISIONAL SPECIFICATION left by the said Timothy Coleman
Blanchflower at the Office of the Commissioners of Patents, with
his Petition, on the 26th June 1868.
I, TIMOTHY COLEMAN BLANCHFLOWER, of Great Yarmouth, in the
County of Norfolk, Bloater Paste Manufacturer, do hereby declare the
nature of the said Invention for "AN IMPROVED MODE OF PACKING PRESERVED
MEATS AND FRUITS FOR SALE," to be as follows:-
This Invention relates to the packing of potted meats, marmalade, and
other like preserves so as to secure them from contact with the air.
It is usual in packing potted meats to coat the upper surface with lard
so as to exclude the air therefrom, but it is not uncommon for the lard
to turn rancid and to deteriorate if not destroy the flavour of the ment

page_text: it was intended to preserve. In covering jams it is also usual to apply
oiled or waxed paper, but this mode of packing does not prevent the
preserves from becoming hard on their upper surface. Now the object
of my Invention is to remedy these defects, and to this end I provide a
disc of glazed earthenware or glass which shall fit the pot that is to
receive the animal or vegetable preserve, and I drop this disc upon and
allow it to rest upon the preserve, by which means the air will be
effectually excluded therefrom. To facilitate the removal and replace-
ment of the disc I form it with a central knob or button, the height of
which will be such as to allow of the ordinary cover of the pot to be
applied as usual. When the cover is put on I lap over the edges of the
pot and cover a band of paper as usual, securing the same by paste or its
equivalent.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Timothy Coleman Blanchflower in the Great Seal
Patent Office on the 26th December 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, TIMOTHY
COLEMAN BLANCHFLOWER, of Great Yarmouth, in the County of Norfolk,
Bloater Paste Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of June, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Timothy Coleman Blanchflower, Her
special licence that I, the said Timothy Coleman Blanchflower, my exe-
cutors, administrators, and assigns, or such others as I, the said Timothy
Coleman Blanchflower, 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 law-
fully 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 "AN IMPROVED MODE OF PACKING PRESERVED MEATS AND
FRUITS FOR SALE," upon the condition (amongst others) that I, the said
Timothy Coleman Blanchflower, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,

page_text: 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 Timothy Coleman Blanchflower, 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 :-
The object of my Invention is to effect the packing of potted meats,
marmalade, and other like preserves so as to secure them from contact
with the air. It is usual in packing potted meat to coat the upper surface
with lard so as to exclude the air therefrom, but it is not uncommon for
the lard to turn rancid and to deteriorate if not destroy the flavour of
the meat it was intended to preserve. In covering jams it is also usual
to apply oiled or waxed paper, but this mode of packing does not prevent
the preserves from becoming hard on their upper surface, and such
defects are now to be remedied by this Invention, which consists in
using a disc of glazed earthenware or glass of such size and shape that
it shall fit the pot or vessel that is to receive the animal or vegetable
preserve, and this disc I place and allow to rest upon the preserve, by
which means the air will be effectually excluded therefrom. To facilitate
the removal and replacement of the disc I prefer that it should have a
central knob or button thereon, the height of which will be such as to
allow of the ordinary cover of the pot being applied as usual. When the
cover is put on I lap over the edges of the pot, covering it with a band
of paper or other similar material as usual, securing the same by paste
or its equivalent. The knob should have an orifice in the centre to
facilitate the exit of the air when the disc is pressed down on to the
preserve (as it ought to be), the pressure forcing a little of the preserve
into the orifice, thereby excluding the air.
Fig. 1, a section of pot or vessel; Fig. 2, plan of same shewing cover
removed. Like letters of reference are used in both Figures to indicate
like parts.

or wax in general use for excluding the air from the preserve; d, the
knob or projection for facilitating the removal and replacement of the
disc; e, the air hole in knob; f, cavity for the preserve.
Having now particularly described the nature of the said Invention,
and ascertained in what manner the same is to be performed and carried
out in practice, I. hereby declare that I claim, the Invention of an
"Improved Mode of Packing Preserved Meats and Fruits for Sale," as
herein described and set forth, it being understood that I do not claim
the particular apparatus or appliances shewn by the accompanying
Drawings, which are hereto annexed for the better illustration and
exemplification of the mode herein described.
In witness whereof, I, the said Timothy Coleman Blanchflower,
have hereunto set my hand and seal, this Twenty-second day of
December, in the year of our Lord One thousand eight hundred
and sixty-eight.
Witness,
TIMOTHY COLEMAN BLANCHFLOWER. (L.S.)
