IMPROVEMENTS IN THE MANUFACTURE OP TIN AND TERNE PLATES
Year: 1865

page_text: LETTERS PATENT to John Jones Jenkins, of Swansea, in the County
of Glamorgan, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE
OP TIN AND TERNE PLATES."
Sealed the 13th October 1865, and dated the 18th April 1865.
PROVISIONAL SPECIFICATION left by the said John Jones Jenkins
at the Office of the Commissioners of Patents, with his Petition, on the
18th April 1865.
I, JOHN JONES JENKINS, of Swansea, in the County of Glamorgan, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF TIN AND TERNE PLATES," to be as follows:-
This Invention relates to certain improvements in the manufacture of tin
and terne plates, whereby greater saving of the coating metal employed is
effected than by the methods hitherto used.
I propose to apply in the trough or vessel containing the grease and tin or
terne metal a pair of vertical rollers, set in adjustable bearings, and in a frame
or block, which is inserted in a slot formed by vertical projecting guides fixed
in the interior of the trough; above these rollers and extending to the end of
the trough a pair of horizontal rollers are arranged in such manner as to
take bearings on the top of the vertical frame or block in sliding journals, in
order that they may be tightened up when necessary by a screw passing
through the sides of the trough and the bearings. The other extremities of
these rollers are held by a pair of journals supported by a projection of the

page_text: upper portion of the trough so as to leave the interior end of the trough flush
with the cylindrical portions of the rollers, and a similar tightening screw is
here applied. The shaft of one of these rollers extends beyond and outside
the trough, so as to receive a crank or pulley for the driving motion. On
each shaft just within the trough a pinion is keyed, and these pinions gearing
together, the motion of one shaft actuates the other in a reverse direction.
The opposite extremity of the driving roller is provided beyond the bearing
with a mitre wheel, which gears into a corresponding wheel keyed hori-
zontally on the top of one of the vertical rollers, and these being provided with
pinions below their lower bearings, it will follow that they also will rotate
reversely. The other portion of the trough is provided with a grate, the level
of which corresponds with the lowest part of the rollers, and the plate to be
treated is to be let down thereon and inserted laterally between the nip of
the vertical rollers, which then immediately draw it underneath the horizontal
rollers and over a lifting grate, the attachments to which are brought upwards
and between the sides of the trough and the rollers; then by means of a
crank handle the grate is slightly elevated, and the plate is in turn inserted
into the nip or bite of the horizontal rollers, and is thus lifted out of the
trough. Tightening screws are to be applied to the vertical rollers in the same
manner as those before described, and it is obvious that by the removal of
the four screws the whole or any part of the apparatus contained in the trough
or vessel may be removed, there being no other fastenings employed.
I am aware that horizontal rollers have been heretofore employed in this
manufacture, but the novelty of my Invention consists in the combination of
vertical rollers, and a grate with the horizontal system of rollers as herein
described. In some cases I employ a greater number of rollers, the system
being the same.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Jones Jenkins in the Great Seal Patent Office on the
18th October 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
JONES JENKINS, of Swansea, in the County of Glamorgan, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of April, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto

page_text: me, the said John Jones Jenkins, Her special licence that I, the said
John Jones Jenkins, my executors, administrators, and assigns, or such
others as I, the said John Jones Jenkins, 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
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN THE MANUFACTURE OF TIN AND
TERNE PLATES," upon the condition (amongst others) that I, the said John
Jones Jenkins, 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 John Jones Jenkins, do hereby
declare the nature of my said Invention, and in what manner the samo is
to be performed, to be particularly described and ascertained in and by the
following statement :-
This Invention relates to certain improvements in the manufacture of tin
and terne plates, whereby a greater saving of the coating metal employed is
effected than by the methods hitherto used.
I apply in the trough or vessel containing the grease and tin or terne metal
a pair of vertical rollers set in adjustable, bearings, and in a frame or block
which is inserted in a slot formed by vertical projecting guides fixed in the
interior of the trough; above these rollers and extending to the end of the
trough a pair of horizontal rollers are arranged in such manner as to take
bearings on the top of the vertical frame or block in sliding journals, in order
that they may be tightened up when necessary by a screw passing through
the sides of the trough and the bearings. The other extremities of theso
rollers are held by a pair of journals supported by a projection of the upper
portion of the trough, so as to leave the interior end of the trough flush with
the cylindrical portions. of the rollers, and a similar tightening screw is
applied here. The shaft of one of these rollers extends beyond and outside
the trough, so as to receive a crank or pulley for the driving motion. On
each shaft just within the trough a pinion is keyed, and these pinions gearing
together, the motion of one shaft actuates the other in a reverse direction.
The opposite extremity of the driving roller is provided beyond the bearing
with a mitre wheel, which gears into a corresponding wheel keyed bori-

page_text: zontally on the top of one of the vertical rollers, and these being provided
with pinions below their lower bearings, it will follow that they also will
rotate reversely. The other portion of the trough is provided with a grate,
the level of which corresponds with the lowest part of the rollers, and the
plate to be treated is to be let down thereon and inserted laterally between
the nip of the vertical rollers, which then immediately draw it underneath the
horizontal rollers and over a lifting grate, the attachments to which are
brought upwards and between the sides of the trough and the rollers; then
by means of a crank handle the grate is slightly elevated, and the plate is in
turn inserted into the nip or bite of the horizontal rollers, and is thus lifted
out of the trough. Tightening screws are to be applied to the vertical rollers
in the same manner as those before described; and it is obvious that by the
removal of the four screws the whole or any part of the apparatus contained
in the trough or vessel may be removed, there being no other fastening
employed.
I am aware that horizontal rollers have been heretofore employed in this
manufacture, but the novelty of my Invention consists in the combination of
vertical rollers, and a grate with the horizontal system of rollers, as herein
described. In some cases I employ a greater number of rollers, the system
being the same.
From the foregoing description the nature and object of my Invention will
be readily comprehended by those conversant with the manufacture of tin and
terne plates.
I annex a Sheet of Drawings in which Fig. 1 represents a longitudinal
vertical section of the apparatus; Fig. 2 being a plan view of the lifting grate.
I have shewn a spring and handle by the side of the pot for the purpose of
driving the plate into the nip of the vertical rollers. By the plate being thus
rolled twice it acquires a better appearance with less quantity of coating
materials. Fig. 3 is an end view of the lifting grate and fingers g. This
grate receives the plate from the vertical rolls, and elevates it to the nip of
the horizontal rolls. The portion a slides in the dovetail of the grate, and is
moved to and fro by means of the slotted hand lever b, Fig. 1, which also
elevates and depresses the grate by its junction with the connecting rod c.
In Fig. 1 the vertical rollers are behind the standard d, and are riot, therefore,
seen in the Drawing. The system of levers c, c, e, serve to actuate the rod f,
which pushes the plate into the nip of the vertical rollers.
Having now described the nature of my said Invention, and the manner in
which the same is to be performed, I would remark in conclusion, that I do not
limit myself to the precise details and configuration of parts which I have

page_text: expressed and shewn, as the same may obviously be varied or modified without
in any degree departing from the principles of the Invention; but what I
claim and desire to be secured to me by the herein in part recited Letters
Patent are, the "Improvements in the Method of Manufacturing Tin and
Terno Plates," substantially as herein specified. :
In witness whereof, I, the said John Jones Jenkins, have hereunto
set my hand and seal, this Sixteenth day of October in the year
of our Lord One thousand eight hundred and sixty-five.
