PROVISIONAL SPECIFICATION left by the said Francis Zysel and
Judah Funkenstein at the Office of the Commissioners of Patents,.
with their Petition, on the 8th June 1874..
WC, FRANCIS ZYSEL and JUDAH FUNKENSTEIN, of Leman Street,
Whitechapel, in the County of Middlesex, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN COOKING UTENSILS MADE OF
TIN OR TINNED IRON," to be as follows:
-
.
:
The object of this Invention is to produce saucepans, coffee pots, tea
kettles, boilers, and other cooking utensils made of tin or tinned iron
stronger and more durable and ultimately less costly than those now

page_text: The said object we effect by the following means:-Instead of fitting
the utensils with an ordinary tin bottom we fix to the body of the
utensil a disc of cast or wrought iron tinned inside. This disc when of
cast iron is formed on its upper side with a groove in and around it near
its outer edge wherein the lower edge of the body of the utensil is placed.
The said bottom edge of such utensil is "wired," that is, a circular ring of
wire is rolled in the tin and thus forms a projection. This wired or pro-
jecting edge is inserted in the said groove and firmly soldered therein.
When wrough iron is used a plate or disc thereof is cut a little larger
than the wired bottom of the utensil, and is fitted thereto by turning up
the projecting part of the said disc and then pressing or hammering
this part over the wired or projecting lower edge of the body, and is also
soldered thereto to make the utensil water-tight.
We further improve these utensils by strengthening the handles
thereof at their junction with the body of such utensils. This we
accomplish by fixing a strip of tin or other metal fitted and soldered to
the handle and rivetted with the ear or socket to the body of the utensil,
which considerably strengthen the handles thereof, especially the handles
of saucepans, coffee pots, and the like, and effectually prevents their being
separated by fire.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Francis Zysel and Judah Funkenstein in the Great
Seal Patent Office on the 4th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FRANCIS
ZYSEL and JUDAH FUNKENSTEIN,; of Leman Street, Whitechapel, in
the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of June, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Francis Zysel and Judah Funkenstein,
Her special license that we, the said Francis Zysel and Judah
Funkenstein, our executors, administrators, and assigns, or such others
as we, the said Francis Zysel and Judah Funkenstein, our executors,

page_text: 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 COOKING
UTENSILS MADE OF TIN OR TINNED IRON," upon the condition (amongst
others) that we, the said Francis Zysel and Judah Funkenstein,
our executors or administrators, by an instrument in writing under our,
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 we, the said Francis Zysel and Judah
Funkenstein, 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:
The object of this Invention is to produce saucepans, coffee pots, tea
kettles, boilers, and other cooking utensils made of tin or tinned iron
stronger, more durable, and ultimately less costly than similar utensils
now in use.
In order that our said Invention may be more clearly and more fully
understood and be more readily performed we now proceed to explain
the same with the aid of the accompanying Drawing, representing a
small saucepan, which Drawing forms part of this Specification,
reference being made thereto by the numerals and letters marked
thereon, and which reference applies to each Figure of the said Drawing
where the same index numerals and letters appear.
Figure 1 is a horizontal plan of our improved cast-iron bottom for
cooking utensils, shewing a circular groove therein; Figure 2 is a section
through the same on the line A, B, Figure 1, showing the method of
fitting the bottom of the body of the saucepan in the said groove;
Figure 3 is a similar section of a wrought-iron disc or bottom.
'
Figure 4 is a side elevation of the saucepan shewing our improved.
method of strengthening the handle thereof; Figure 5 is a back eleva-.

page_text: tion of the same shewing the position of the rivets which secure the
strengthening piece to the body of the utensil.
Instead of fitting cooking utensils with an ordinary tin or tinned-iron
bottom we fix to the body a of the utensil a disc or plate of cast or
wrought iron b, b', tinned inside. This disc or plate when made of cast
iron is formed on its upper side with a groove c in and around it near to
its edge or periphery, in which groove c the lower edge of the body of
the utensil is placed or fitted and securely soldered therein, the said
bottom edge of such utensil being previously "wired," that is, a circular
ring of iron or other wire is rolled in the tin, and thus forms a projec-
tion & outside the utensil, as shewn in Figure 2. When wrought iron
is used a disc or plate thereof is cut a little larger than the bottom of
the utensil when turned up or flanged, and is fitted or fixed thereto by
turning up the projecting part of such disc or plate, as at 62, and then
pressing or hammering this turned-up part over and closely upon the
said projecting or turned-up lower edge d of the utensil. Or the joint
is made by folding the edge of the bottom over the turned-up lower edge:
of the body of the utensil in the usual way so as to make a good and
durable water-tight joint. If desired the joint may also be soldered as
an additional security.
We further improve cooking and other similar utensils by strengthen-
ing the handles e thereof at their junction with the body of the utensils.
This we accomplish by fitting and soldering a piece of sheet metal f to
the handle e and rivetting the said piece of metal f with the ear or
socket e' of the handle e to the body of the utensil, see Figure 5. This
latter improvement not only considerably strengthens the handles of
such utensils, especially projecting handles as those of saucepans, coffee
pots, and the like, but it effectually prevents them being separated by
fire from the body of the utensil.
Having thus fully described the nature of our said Invention and the
method of performing the same, without confining ourselves to the shape
or thickness of the plates or discs now illustrated as they admit of much
variation, nor to the shape and thickness of the strengthening-piece f
we claim as our Invention and desire to secure by the herein-before
mentioned in part recited Letters Patent the use and application of
cast-iron and wrought-iron bottoms to tin or tinned iron cooking utensils

page_text: and the method of strengthening the handles of such utensils, all sub-
stantially as herein described and shewn in the Drawing.
In witness whereof, I, the said Judah Funkenstein, on behalf
of myself and the said Francis Zysel, have hereunto set my hand
and seal, this Third day of December, in the year of our Lord One
thousand eight hundred and seventy-four.
