Year: 1841

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
BROWN, of Gravel Lane, Southwark, Engineer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Eleventh day of August, in the fifth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Samuel
Brown, Her especial licence, full power, sole privilege and authority, that I,
the said Samuel Brown, my exors, admors, and assigns, or such others as
I, the said Samuel Brown, my exors, admors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the
term of years therein expressed, should and lawfully might make, use, exercise,
and vend, within-England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF METALLIC CASKS OR
VESSELS, AND IN TINNING OR ZINCING METAL FOR SUCH AND OTHER PURPOSES;"
in which said Letters Patent is contained a proviso, that I, the said Samuel
Brown, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be inrolled in Her said
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
and by the same, reference being thereunto had, will more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Brown, do hereby declare the nature of my said Invention, and the

page_text: manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement, reference being had to the Drawings
hereunto annexed, and to the figures and letters marked thereon, that is to
say:
My Invention relates, first, to a mode of fixing the heads or ends of metal
casks and other vessels by means of tinning or soldering. And secondly, my
Invention relates to an improvement of the apparatus used for tinning or
zincing sheets of metal.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the means pursued by me.
DESCRIPTION OF THE DRAWING.
Figure 1 represents the section of a furnace; Figure 2, a plan thereof, for
keeping a quantity of tin or an alloy of tin in a melted state, for making the
joints when affixing heads or ends of casks or other vessels, according to the
first part of my Invention; a represents a cast-iron trough or vessel, in which
tin or an alloy of tin is kept melted. Figure 3 represents part of a section of
a metallic cask or vessel; b representing one of the heads or ends to be fixed
and made fluid-tight at the joint; the head 6 is simply forced into one end of
the cask or other vessel, Figure 3; and in order to fix it, that end of the cask
is to be immersed in the fluid metal in the trough a, and remain therein for
four or five minutes, when the melted metal will enter the joint around the
head, and when the cask is removed and the melted metal in the joint has
become cold, the head 6 will be securely fixed and the joint will be fluid-tight.
In some cases I apply a hoop c, driven on the end of the cask or vessel before
submitting the end of the cask or vessel to the melted metal, by which means
the end of the cask will be strengthened and the whole of the surfaces will be
affixed to each other. I would remark, that in the above description I have
supposed that the metal employed in making the cask or vessel and the head
or end thereof, and the hoop applied thereto, have had their surfaces tinned;
it should also be stated that in order to facilitate the entrance of the melted
metal into the joints in affixing a head or a hoop to a cask or other vessel,
previous to dipping the end of the cask into the vessel a, I press the end of a
cask on to a surface of powdered rosin. By this mode of fixing, the heads or
ends of casks or other vessels will simply require to be driven in or on the
ends of the vessels, and then the joint made good by simply immersing in it a
bath of melted metal.
I will now describe the second part of my Invention, which has for its object
a means of tinning or zincing large sheets of metal. Figure 4 shews the

page_text: section of a furnace for keeping a bath of tin or an alloy of tin, or a bath of
zinc, in a melted state, in which the sheets of metal to be coated are to be
immersed; Figure 4 also shews the section of a hot plate, on which the sheets
of metal, when taken from the bath, are to be laid, in order to have the
superfluous metal wiped off; Figure 5 shews a plan of Figure 4; Figure 6
shews a plan of Figure 4 in section, the hot plate and the iron vessel for the
bath being removed, by which the construction of the furnaces and their flues
will be more readily understood; Figure 7 is a transverse section of the metal
bath and its furnace; Figure 8 is a transverse section of the hot plate and its
furnace; d is a cast-iron vessel, in which the melted metal for coating is kept
heated by the furnace e, and the flames and heat passing through the openings
of the arch at ff, and thence away by the flues g to the chimney, there being
a damper h to regulate the heat; i, i, is what I call a hot plate, the object of
it being to keep the coating metal in a fluid state on the surfaces of the sheets
of metal when laid on the hot plate, in order to allow of the surplus metal
being wiped off. In tinning sheets of metal which may be of large dimensions,
the workman having cleansed the surfaces by pickling and otherwise, as is well
understood, places the sheets of metal in a trough containing powdered rosin,
and then passes them one at a time into the bath of melted metal, and allows
them to remain immersed for from five to ten minutes, and if on raising a
sheet of metal to the surface any part or parts are not found to be coated, he
is to throw on powdered rosin and to rub it on to such parts as are not coated,
and again immerse the sheet in the bath, and when he finds, on examining a
sheet of metal, that it is coated all over, he is to withdraw it from the bath
and place it on the hot plate; then, by means of tow he is to wipe off the.
superfluous metal, first from one side and then from the other; the hot plate
keeping the coating metal melted on the surfaces, to allow of that operation.
Having thus described the nature of my Invention and the manner in which
the same is to be performed, I would have it understood that what I claim is,-
First, the mode of fixing the heads or ends of casks or other vessels by
immersing the ends of such vessels in a bath of suitable melted metal as
above described.
And, secondly, I claim the mode of keeping sheets of metal heated (in order
to the superfluous coating metal being removed) by the application of a hot
plate, as above described.
In witness whereof, I, the said Samuel Brown, have hereunto set my
hand and seal, this Eleventh day of February, One thousand eight
hundred and forty two
