Improvements in Preparing Metal Plates or Sheets for Coating
with Tin and other Metals.
We, JOHN HUNT LONES, of Bucklands, Lydney, in the County of Gloucester, Mill
Foreman, and JOHN WAITE, of Bath House, Station Road, in Lydney, aforesaid,
Tinhouse Superintendent, do hereby declare the nature of this invention to be as
follows:-
The object of our invention is to provide simple but very efficacious means for
preparing metal plates and sheets for coating with tin and other metals that will so
prepare them and then pass them into the tinning or other pot with a minimum of
labour in a very sure and certain manner.
To carry out this object we mount across and at or near the entering end of the
tinning or other pot a certain number of pairs of rolls preferably perhaps three pairs
of which the first pair are provided with the desired and appropriate rubber bands
while the second pair are covered with sheepskin or other suchlike and suitable
material and the third pair are provided with similar rubber bands. Between the
first pair and the second pair of rolls are fitted and arranged two water pipes above
and below where the plate is to pass which are preforated or otherwise so treated that
both the top and bottom surfaces of the plate will be thoroughly and entirely washed
while such plate is passing between thein. The first pair and the third pair of rolls
are fitted to hold and pass along the plate and are therefore revolved in the same
directions and at the same speed but the second pair of rolls are fitted to clear the
plate after it has been washed and are therefore preferably revolved also in the same
directions but at an increased speed although they may also be revolved in the
contrary directions at the desired speed. In either case the plate is thoroughly
washed and brushed or rubbed clean while it is passing from the first pair to the third
pair of rolls and is therefore fit to be delivered directly from the third pair of rolls
by and along suitable guides through the flux into the molten metal in the pot to be
coated thereby in the usual or other manner.
Whenever it may be expedient so to do other two pairs of rolls similar to the
aforesaid first and second pairs of rolls with or without the interposed water pipes
may be provided and the plate could be passed through them all in due
sequence.
When it may be desired to dispense with that stage of the ordinary process of
preparing the plates for tinning called "white-pickling ' or whenever it may be
deemed expedient so to do other pairs of rolls are mounted in front of and to treat
the plate before the aforesaid pairs of rolls preferably perhaps four pairs of rolls of
which the first and third pairs are provided with the desired and appropriate rubber
bands while the second and fourth pairs are covered either wholly or partially with
emery or other suchlike and suitable material. The first pair and the third pair of
rolls are fitted to hold and pass along the plate and are therefore revolved in the same
directions and at the same speed but the second pair and the fourth pair of rolls
are fitted to burnish or polish the surfaces of the plate and are therefore prefer-
ably revolved also in the same directions but at an increased speed although they

page_text: may also be revolved in the contrary directions at the desired speed. In either case
the surfaces of the plate are thoroughly polished while such plate is passing through
these four pairs of rolls and therefore when washed and brushed as aforesaid this
plate is fit to be coated by the molten metal.
In this apparatus also other two pairs of rolls similar to the aforesaid first and
second pairs of rolls may be provided and the plate could be passed through them all
in due sequence.
All the rolls are made long enough to adinit and treat one or two or more plates at
the same time as may be advisable in each case and they are preferably so mounted
and arranged in respect of each other and of the tinning or other pot that when a
plate has been entered between the first pair of rolls no more hand guidance or other
labour is needed.
Improvements in Preparing Metal Plates or Sheets for Coating
with Tin and other Metals.
We, JOHN HUNT LONES, of Bucklands, Lydney, in the County of Gloucester, Mill
Foreman, and JOHN WAITE, of Bath House, Station Road, in Lydney, aforesaid,
Tinhouse Superintendent, do hereby declare the nature of my said invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The object of this our invention is to provide simple but very efficacious means
and apparatus for preparing metal plates or sheets for coating with tin and other
metals that will so duly and properly prepare them and then pass them into the
tinning or other pot with a minimum of labour in a very sure and certain manner.
In order the more clearly to explain this our invention and in what manner the
same is to be performed we refer to the accompanying drawing wherein
Figure is a plan of our complete apparatus and
Figure 2 is a vertical section of the same taken at a, b, in Figure 1.
A is an ordinary tinning or other pot and at the entering end of this pot A is or
may be provided a suitable table B which can be supported by the standards B¹ and
is properly formed and arranged to support our apparatus. On this table B if any
and across and at or near this entering end of the pot A are duly mounted in
ordinary standards and in any customary and appropriate and it may be adjustable
manner a certain number of pairs of rolls of metal or other suitable material
preferably perhaps three pairs of rolls as is shewn in the drawing of which pairs the
first pair of rolls C are it may be provided at the desired intervals with appropriate
rubber bands D of the desired breadth and thickness while the second pair of rolls E
are covered with sheepskin F or other suchlike and suitable material preferably of
the full breadth of the plate that is to be treated in and by this apparatus and of the
desired thickness and the third pair of rolls G are provided with rubber bands H it
may be similar to the bands D herein before described. Between the pair of rolls C
and the pair of rolls E are fitted and arranged two horizontal pipes K and K¹ above
and below and in the due proximity to the place where the plate is to pass which
pipes K and K¹ are perforated or otherwise so treated and are so supplied with water
or other suitable liquid that both the upper and lower surfaces of the plate
can and will be thoroughly and entirely washed while such plate is passing between
them.

page_text: The pair of rolls C and the pair of rolls G are fitted and arranged and if need be
adjusted in respect of each other to hold and clasp between the bands D and H if
any and to pass along the plate and are therefore in any convenient and usual or
other manner and by any appropriate gearing or the like revolved in the same
directions and at the same speed but the pair of rolls E are fitted and arranged and
if need be adjusted in respect of each other to clean the plate by the sheepskin For
the like after it has been washed and are therefore similarly in any convenient and
usual or other manner and by any appropriate gearing or the like preferably revolved
in the same directions as the pairs of rolls C and G but at an increased speed
although they may also when advisable be similarly revolved in the contrary
directions to the same at any desired speed. In either case the plate is thoroughly
washed and brushed or rubbed clean while it is passing from the pair of rolls C to
the pair of rolls G and is therefore in a proper and fit condition to be delivered
directly from the pair of rolls G by and along suitable guides or the like through
the flux into the molten metal in the pot A in the customary manner to be coated
by such metal in the usual or other manner and to ensure such due deliverance it
may generally be advisable to incline the line of the axes of the pair of rolls G over
the pot A as is shewn in the drawing. It may further be desirable so to mount all
these pairs of rolls that the whole apparatus can easily and quickly be moved out of
the way to afford free access to the pot and this can be effected and arranged for in
any appropriate and usual or other manner.
Whenever it may be expedient so to do other two pairs of rolls similar to the two
pairs of rolls C and E hereinbefore described and with or without the afores id
interposed water or other pipes may be provided and the plate could be passed through
and between them all in due sequence.
When it may be desired to dispense with that stage of the ordinary process of
preparing the plates for tiuning commonly called "white pickling "as also whenever
it may be deemed expedient so to do the apparatus now to be described may be
provided and arranged in due juxtaposition with and in front of the apparatus
herein before described to treat the plate before it enters such apparatus.
It may be on the same table B if any and parallel with and on the same level as
the pair of rolls Chereinbefore described are similarly mounted in ordinary standards
and in any customary and appropriate and it may be adjustable manner a certain
number of pairs of rolls of metal or other suitable material preferably perhaps four
pairs of rolls as is shewn in the drawing of which pairs the first pair of rolls L and the
third pair of rolls R are it may be provided at the desired intervals with appropriate
rubber bands M and S respectively of the desired breadth and thickness while the
second pair of rolls N and the fourth pair of rolls T are covered with emery P and V
respectively or other such like and suitable material which emery or the like may be in
separate bands of the desired breadth as is shewn at P or may be the full breadth of
the plate that is to be treated in and by this apparatus as is shewn at V and is of the
desired thickness. In the former case the bands of emery or the like ought obviously
to be so arranged that the entirety of the surfaces of the plate will be duly treated
thereby while such plate is passing between them.
The pair of rolls L and the pair of rolls R are fitted and arranged and if need be
adjusted in respect of each other to hold and clasp between the bands M and S if
any and to pass along the plate and are therefore in any convenient and usual or
other manner and by any appropriate gearing or the like revolved in the same
directions and at the same speed as the pairs of rolls and G hereinbefore described
but the pair of rolls N and the pair of rolls T are fitted and arranged and if need
be adjusted in respect of each other to burnish or polish the plate by the emery or
the like and are therefore similarly in any convenient and usual or other manner
and by any appropriate gearing or the like preferably revolved in the same directions
as the pairs of rolls L and R but at an increased speed although they may also
when advisable be similarly revolved in the contrary directions to the same at any
desired speed. In either case the plate is thoroughly burnished or polished while
it is passing through and between these four pairs of rolls and therefore when

page_text: afterwards washed and brushed as is herein before described this plate is in a proper
and fit condition to be coated by the molten metal.
In this apparatus also whenever it may be expedient so to do other two pairs of
rolls similar to the two pairs of rolls L and N hereinbefore described may be provided
and the plate could be passed through and between them all in due sequence.
It is perhaps generally most expedient to provide the alternate pairs of rolls that
hold and pass along the plate with the rubber bands hereinbefore described and
shewn in the drawing for we consider that thereby the plate is more efficiently
clasped and therefore is more surely and duly so passed along but we do in no wise
limit ourselves thereto for these alternate pairs of rolls may when desired be entirely
bare and be completely uncovered or may be completely or partially covered with
any suitable and usual or other material.
This apparatus and all the rolls thereof can be made broad enough and long
enough to admit and treat one or two or more plates at the same time edge to edge
as may be advisable in each particular case and in the accompanying drawing we
have shewn the same as arranged to admit and treat two plates edge to edge.
When this apparatus as is preferable is arranged as is shewn in the drawing it is
obvious that a plate entered between the pair of rolls L will need no more hand
guidance or other labour until it is discharged into the tinning or other pot A and
during its passage through this apparatus will be duly and properly prepared for
coating with the tin or other metal in such pot A as is desired.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. The combination with a tinning or other pot of three or more pairs of rolls
between which the plate is to pass on its way to such pot and of which the last and
each alternate pair of rolls are holding rolls for the plate while the other alternate
pair of rolls are brushing rolls for the plate and therefore are provided with sheep-
skin or the like and two horizontal pipes perforated for discharging water or the like
to wash both surfaces of the plate before it enters between the brushing rolls means
being provided for duly revolving all the rolls substantially as and for the purposes
hereinbefore described and declared.
2. The combination with the apparatus herein before claimed of four or more pairs
of rolls between which the plate is to pass on its way to such apparatus and of which
the first and each alternate pair of rolls are holding rolls for the plate while the other
alternate pair of rolls are burnishing rolls for the plate and therefor are provided
with emery or the like means being provided for duly revolving all the rolls
substantially as and for the purposes hereinbefore described and declared.
3. The arrangement and combination of parts and appliances constituting our
improvements in preparing metal plates or sheets for coating with tin and other
metals substantially as herein before described and shewn in the accompanying
drawing.
