page_text: LETTERS PATENT to Edward Griffith Brewer, of 89, Ohancery Lane,
in the County of Middlesex, Patent Agent, for the Invention of
"IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR CONSTRUCTING AND
FORMING METALLIC JOINTS OR SEAMS OF TIN OR OTHER SHEET METAL. -
A communication from abroad by Joseph Le Comte, of the City of
Brooklyn, in the State of New York, United States of America.
PROVISIONAL SPECIFICATION left by the said Edward Griffith Brewer
at the Office of the Commissioners of Patents, with his Petition,
on the 18th February 1869.
I, EDWARD GRIFFITH BREWER, of 89, Chancery Lane, in the County
of Middlesex, Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR CON-
STRUCTING AND FORMING METALLIC JOINTS OR SEAMS OF TIK OR OTHER SHEET
METAL," (a communication from abroad by Joseph Le Comte, of the
City of Brooklyn, in the State of New York, United States of America,)
to be as follows:-
The first part of this Invention consists in uniting the edges or other

page_text: parts of tin or other sheet metal plates so as to produce a perfect water,
oil, or air tight joint or seam by means of heat and pressure effected by
suitable machinery capable of uniformly pressing each part of the same
into a solid mass without the application of the soldering iron or any
additional solder or amalgam beyond that which is contained upon the
metallic plates themselves.
The second part relates to machinery or apparatus for carrying the
first part into effect, although any suitable power, such as pneumatic,
hydrostatic, or steam, may be used.
The apparatus consists of a framework containing a fire-box, revolving
fire-grate bars, a hollow anvil or arm forming a portion of the flue
through which the products of combustion pass; it may be of a
cylindric form or of any other desirable shape to correspond with the
form of the can or other vessel to be made. A mandrel fitted with steel
dies is placed above the anvil and operated by a lever and screw, although
any other power may be employed. The arm or anvil is heated by means
of the heat from the fire-box, and which passes up through the flue in
the arm to the chimney at the lack of the machine, consequently the
arm or anvil is sufficiently heated by the escaping heat during its course
to the chimney for soldering purposes. When the tin is laid the
heated arm it also becomes hot and is firmly pressed upon the hot
anvil by means of the-steel dies upon the lower end of the vertical
mandrel, and which latter is forced down by the action of the lever and
scrow or by any equivalent power or force upon the hot plates, and
in such manner that a proper union of the edges or other parts of the
plates is produced while in a hot state by the mechanical combination
before described, but which is subject to modification to suit the different
kinds of joints or seams to be united by heat and pressure produced in
the manner before described. In this manner joints or seams of any
shape or form may be produced.
upon
By this Invention the work is completed almost instantaneously in a
perfect and workmanlike manner with less labour, time, and expense than
by any other device heretofore used for soldering metal plates that aro
coated with tin, lead, zinc, or other fusible alloys; at the same time a
great saving of solder is effected and a more uniform and stronger union
produced by heating both, if preferred, before producing the requisite
pressure to complete the work.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Griffith Brewer in the Great Seal Patent
Office on the 13th August 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
GRIFFITH BREWER, of 89, Chancery Lane, in the County of Middlesex,
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of February, in the
year of our Lord One thousand cight hundred and sixty-nine, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Edward Griffith Brewer,
Her special licence that I, the said Edward Griffith Brewer, my
executors, administrators, and assigns, or such others as I, the said
Edward Griffith Brewer, 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 King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN THE METHOD OF AND APPARATUS
FOR CONSTRUCTING AND FORMING METALLIC JOINTS OR SEAMS OF TIE OR OTHER
SHEET METAL," (a communication from abroad by Joseph Le Comte,
of the City of Brooklyn, in the State of New York, United States of
America,) upon the condition (amongst others) that I, the said Edward
Griffith Brewer, 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 Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Edward Griffith Brewer, 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, reference being had to the accompanying
Drawings, and to the letters of reference marked thereon, that is to
Bay:
The first part of this Invention consists in uniting the edges or other

page_text: parts of tin or other sheet metal plates so as to produce a perfect water,
oil, or air tight joint or seam by means of heat and pressure effected by
suitable machinery capable of uniformly pressing each part of the same
into asolid mass without the application of the soldering iron or of any
additional solder or amalgam beyond that which is contained upon the
metallic plates themselves.
The second part relates to machinery or apparatus for carrying the
first part into effect, although any suitable power, such as pneumatic,
hydrostatic, or steam, may be used.
The apparatus consists of a framework containing a fire-box, revolving
fire-grate bars, a hollow anvil or arm forming a portion of the flue
through which the products of combustion pass; it may be of a
cylindrical form or of any other desirable shape to correspond with the
form of the can or other vessel to be made. A mandrel fitted with
steel dies is placed above the anvil and operated by a lever and screw,
although any other power may be employed. The arm or anvil is
heated by means of the heat from the fire-box, and which passes up
through the flue in the arm to the chimney at the back of the machine,
consequently the arm or anvil is sufficiently heated by the escaping heat
during its course to the chimney for soldering purposes. When the tin
is laid upon the heated arm it also becomes hot, and is firmly pressed
upon the hot anvil by means of the steel dies upon the lower end of the
vertical mandrel, and which latter is forced down by the action of the
lever and screw or by any equivalent power or force upon the hot plates,
and in such manner that a proper union of the edges or other parts of
the plates is produced while in a hot state by the mechanical com-
bination before described, but which is subject to modification to suit
the different kinds of joints or seams to be united by heat and pressure
produced in the manner before described. In this manner joints or
scams of any shape or form may be produced.
By this Invention the work is completed almost instantaneously in a
perfect and workmanlike manner with less labour, time, and expense
than by any other device heretofore used for soldering metal plates that
are coated with tin, lead, zinc, or other fusible alloys; at the same time
a great saving of solder is effected and a more uniform and stronger
union produced by heating both, if preferred, before producing the
requisite pressure to complete the work.
Figure 1 of the accompanying Drawings is a perspective view of one

page_text: of my machines A. for soldering or uniting the edges or other parts of
metallic plates by pressure produced by any suitable power, such as
pneumatic, hydrostatic, steam, or by the application of a lever O and
screw S, in combination with heat obtained as shown in the Drawings,
or from any other source or means that will heat the plates through the
arm H or otherwise; Figure 2 is a vertical section of Figure 1 showing
the body of the machine A with fire-box B, and revolving fire-grate
bars, also the heated arm or anvil H, with fire-flue F, mandrel M, with
steel die and screws and chimney D; Figure 3 shows a single joint or
seam; Figure 4, a single lock or rib joint; Figure 5, a double joint for
inside or out; Figure 6, a common lock or roofing joint; Figure 7, a
common grooved or countersunk seam or joint; Figure 8, a single lap
joint or seam; Figure 9, a right angle or elbow joint; Figure 10, a
curved joint or seam.
In order to produce either of the above joints or seams by pressure
the arm or anvil H is first heated, see Figures 1 and 2 of the machine,
which imparts the necessary amount of heat to the tin, lead, or other
plates during the process of pressing or forming the joint or joints.
By the application of either of the above powers, for example, the
lever C and screw 8, the work is completed instantaneously in a perfect
and workmanlike manner at less labor, time, and expense than by any
other device ever used for soldering metal plates that are coated with
tin, lead, zinc, or other fusible alloys; at the same time a great saving
of solder and a more uniform and stronger union are produced by heating
the machinery or the plates or by heating both (if preferred) pre-
paratory to producing the pressure requisite to complete the work. The
arm or anvil H may be of a cylindrical or of any other desirable shape
that will correspond with the form of the can or other vessel to be made.
This arm or anvil H is heated by means of the heat from the fire-
box B, Figures 1 and 2, which passes up through the flue F in the
arm H to the chimney D at the back of the machine A, consequently
the arm or anvil becomes heated by the escaping heat during its course
to the chimney sufficiently hot for soldering purposes. When the tin
is laid upon the heated arm H it also becomes hot, and it is firmly
pressed upon the hot anvil by means of the steel dies upon the bottom
of the vertical mandrel, which is forced down by the action of the
lever O and screw S or by an equivalent power or force upon the hot
plates, so that a proper union of the edges or other parts of the tin

page_text: plates is produced while in a hot state by the mechanical combination,
as above described, which is subject to modifications to suit the different
kinds of joints or seams to be united by heat and pressure produced in
the manner as above set forth.
Consequently the novelty of this Invention' does not consist in turning
or forming the edges of the tin or metal plates into any desired shape
or form; but it docs consist in the process or manner of producing a
perfect water, oil, or air tight seam or joint by pressure effected by
suitable machinery that will uniformly press each part of the same into
a solid mass without the application of the soldering iron or of any
additional solder or amalgam beyond that which is contained the
metallic plates themselves when sold in market.
upon
And having now described the nature of the said Invention, and
in what manner the same is to be performed, I declare that I claim,-
First. The machine A with the hollow arm or anvil H, fire-box B, and
flue F, revolving fire-grate mandrel M and dies, screw S and lever C,
or their equivalent power, chimney D, all arranged substantially as
described and shown in the Drawings or otherwise arranged to suit the
different kinds of work.
Second. I claim heat and pressure when produced by any suitable
machinery for the purpose of uniting the edges or other parts of tin or
other sheet metal plates for the purpose set forth.
In witness whereof, I, the said Edward Griffith Brewer, have
hereunto set my hand and seal, this Eleventh day of August,
in the year of our Lord One thousand eight hundred and sixty-
nine.
