IMPROVED MEANS AND APPARATUS FOR FINISHING TIN AND TERNE PLATES
Year: 1875

page_text: LETTERS PATENT to George Nurse, of Pen y Van, near Pontymister,
in the County of Monmouth, for the Invention of " IMPROVED
MEANS AND APPARATUS FOR FINISHING TIN AND TERNE PLATES."
Sealed the 12th May 1876, and dated the 15th November 1875.
PROVISIONAL SPECIFICATION left by the said George Nurse at the
Office of the Commissioners of Patents, with his Petition, on the
15th November 1875.
I, GEORGE NURSE, of Pen y Van, near Pontymister, in the County
of Monmouth, do hereby declare the nature of the said Invention for
"IMPROVED MEANS AND APPARATUS FOR FINISHING TIN AND TERNE PLATES,"
to be as follows:-
This Invention relates to special means and apparatus for finishing
tin and terne plates, and consists in arranging ordinary tinned or terne
plates in a revolving frame or rack within a vessel in which is enclosed
a bottom coil of piping and also a wall of pipe or pipings through which
hot water, steam, or other agent of heat is passed. Between the bottom

page_text: of the revolving rack and above or beneath the bottom coil of pipes I
fit a screen, set at an incline, and upon which the superfluous tin or
terne is permitted to fall and flow towards an outlet to be removed
when desired.
Instead of the vessel having a screen I arrange the bottom of the
rack with an incline to lead the superfluous metal to the lower corner
of each plate, or the lower part of the frame may be so made that the
plates can be cocked up on edge to lie in a tilted position.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Nurse in the Great Seal Patent Office on
the 15th May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
NURSE, of Pen-y-Van, near Pontymister, in the County of Monmouth,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-five, in
the thirty-ninth year of Her reign, did,' for Herself, Her heirs and
successors, give and grant unto me, the said George Nurse, Her special
license that I, the said George Nurse, my executors, administrators, and
assigns, or such others as I, the said George Nurse, my executors, admi-
nistrators, 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 "IMPROVED MEANS AND
APPARATUS FOR FINISHING TIN AND TERNE PLATES," upon the condition
(amongst others) that I, the said George Nurse, 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.

page_text: NOW KNOW YE, that I, the said George Nurse, 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 relates to special means and apparatus for finishing
tin and terne plates, and consists in arranging ordinary tinned or terne
plates in a revolving frame or rack within a vessel in which is enclosed
a bottom coil of piping and also a wall of pipe or pipings through
which hot water is passed. Between the bottom of the revolving rack
and above or beneath the bottom coil of pipes I fit a screen, set at an
incline, and upon which the superfluous tin or terne is permitted to fall
and flow towards an outlet, to be removed when desired.
Instead of the vessel having a screen I arrange the bottom of the
rack with an incline to lead the superfluous metal to the lower corner
of each plate, or the lower part of the frame may be so made that the
plates can be cocked up on edge to lie in a tilted position.
My Invention is clearly shown in the annexed Sheet of Drawings, in
which A is the vessel; B, the bottom coil of piping; C, the wall of
piping, which may have separate supply of water from the bottom
piping, or the water may flow first through one and then through the other,
before sufficient heat being thereby obtained to cause the superfluous tin
and terne to become detached from the plates which are upon the rack D
of the frame E, which has a revolving motion imparted to it by hand
from the wheel F, or in other convenient manner. The wheel F is
attached to a vertical central stem or shaft G, to the lower end of which
the rack frame E is fixed, so that it rotates with the upright G. H is
a screen tilted or canted in order that the superfluous tin or terne as it
falls from the plates may be caught thereon and flow down to the
lower point, where it finds an outlet by the pipe I.
The heat from the bottom coil and the wall of piping is taken up by
the rack frame and the screen, as well as by the plates which are
arranged between the bars of the rack in single order to keep them
separate, that the heat may act equally upon both surfaces. L is the
cavity through which the plates are inserted and removed.
The plates to be treated can be set up on edge, or they may be cocked
up so that the superfluous tin or terne may flow off at the lower corners
