Year: 1868

page_text: LETTERS PATENT to Julius Augustus Farwig, of Sellnurst, South
Norwood, in the County of Surrey, Merchant, and Charles Haynes,
of No. 7, Bermondsey New Road, in the County of Surrey, Tin
Plate Worker, for the Invention of "IMPROVEMENTS IN THE MANU-
FACTURE OF SHEET METAL CASES."
Scaled the 25th May 1869, and dated the 8th December 1868.
PROVISIONAL SPECIFICATION left by the said Julius Augustus Farwig
and Charles Haynes at the Office of the Commissioners of Patents,
with their Petition, on the 8th December 1868.
JULIUS AUGUSTUS FARWIG, of Selhurst, South Norwood, in the
County of Surrey, Merchant, and CHARLES HAYNES, of No. 7, Bermondsey
New Road, in the County of Surrey, Tin Plate Worker, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE
OF SHEET METAL CASES," to be as follows:-
This Invention has for its object the manufacture of sheet metal
casks with four equal sides, the heads and bottoms having flanches
(raised by dies or forcers), which heads and bottoms are placed in their

page_text: positions inside the body of the casks, then dipped or soldered, and
rivetted in the ordinary way. The body is made in four equal parts bent
at right angles, and joined together with the usual lap-jointed double
seams in centres. The top of the cask is made concave and convex for
the purpose of strengthening the top of the cask, and the former or 5
concave forming an air chamber. The body and bottom are made with
convex or hollow flutes, and when extra strength is required that is
produced by soldering or fastening to the inside of the cask tinned wire
or other metallic ribs.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
-filed-by-the-said Julius Augustus Farwig and Charles Haynes in
the Great Scal Patent Office on the 8th June 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JULIUS
AUGUSTUS FARWIG, of Selhurst, South Norwood, in the County of
Surrey, Merchant, and CHARLES HAYNES, of No. 7, Bermondsey New
Road, in the County of Surrey, Tin Plate Worker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of December, 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 us, the said Julius Augustus Farwig
and Charles Haynes, Her special licence that we, the said Julius
Augustus Farwig and Charles Haynes, our executors; administrators, and
assigns, or such others as we, the said Julius Augustus Farwig and
Charles Haynes, our 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 Inven-
tion for "IMPROVEMENTS IN THE MANUFACTURE OF SHEET METAL CASES," upon
the condition (amongst others) that we, the said Julius Augustus Farwig
and Charles Haynes, our executors or administrators, by an instrument
in writing under our or their hands and seals, or under the hand and
seal of one of us or them, should particularly describe and ascertain the

page_text: 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 Julius Augustus Farwig aud
Charles Haynes, 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 the manufacture of sheet metal
casks. We make metal casks with four equal sides, the heads and
bottoms having flanches, which heads and bottoms are placed in their
positions inside the body of the casks, then dipped or soldered and rivetted
in the ordinary way. The body is made in four equal parts bent at right
angles and joined together with the usual lap-jointed double seams in
centres. The top of the cask is made concave and convex for the
purpose of strengthening the top of the cask, and the concave forms an
air chamber. The body and bottom are made with convex or hollow
flutes, and when extra strength is required that is produced by soldering
or fastening to the inside of the cask tinned wire or other metallic ribs.
And in order that our said Invention may be most fully understood
and readily carried into effect, we will proceed to describe the Drawings
hereunto annexed.
sticet mictal
cask, constructed according to our Invention; Figure 3 is a horizontal
section of the cask.
a, a, are the sides which are corrugated, as is shown by stamping them
between dies, they are joined together at a with lap-jointed double
scams.
Figures 4 and 5 are transverse sections of the head or top, and the
bottom may be similarly formed, but without the handle it is made
convex and concave as is shown, and the concavity forms a space in
which air will remain when the cask is filled, and so allow room for the
contents to expand and contract with changes of temperature. The
joints of the sides are soldered, the top and bottom are formed with
flauges as is shown bent up and lapped over the edges of the sides all

page_text: round, the joints are soldered either by dipping into a solder bath or by
hand, and rivets are inserted at b', ', and soldered over; is the handle,
and the bung or filling hole.
Having thus described the nature of our said Invention, and the
manner of performing the same, we would have it understood that what 5
we claim is, the constructing sheet metal casks with corrugated or fluted
-sides, and with a concave and convex head top or end, substantially as
herein described.
In witness whereof, we, the said Julius Augustus Farwig and
Charles Haynes, have hereunto set our hands and seals, this 1
Seventh day of June, in the year of our Lord One thousand eight
hundred and sixty-nine.
