Coated Plates and in the Apparatus Employed therein.
I DAVID OWEN of Brookfield House Morriston near Swansea in the County of
Glamorgan Tin-plate Manufacturer, do hereby declare the nature of this invention to
be as follows:-'
These improvements relate to the manufacture of tin plates and such like metal
coated plates and the object of the invention is to economise the amount of tin used in
the tinning operation and otherwise to improve the results attained.
In carrying out my invention I provide a vessel for holding grease or flux into
which the plates in turn are passed between a pair or other number of rollers covered
with felt or other suitable material. This grease or flux containing chamber is closed
against escape of grease by the molten metal of the tinning pot below into which the
plates hence pass between a pair or pairs of rollers into a cradle, frame, or guideway
capable of adjustment by means of screws or equivalent means and by means of spring
pressure such as a spiral spring or springs the lower part of this frame is adapted to
be depressed by the incoming plate and as soon as the rolls are reversed and the plate
released the plate is caused to be pressed up so as to be passed out or into another
vessel containing a finer description of grease or other suitable matter.
In some cases I employ a preparatory bath of grease into which the plates are
placed to soak or have prolonged contact with the grease or flux before entering the
first described chamber and this may either be effected by hand or by an automatic
arrangement of finger levers or like gripping means and with releasing parts.
As it is desirable that the entering motion for the tin plates into the tinning pot
should be slower than the returning motion so as to give adequate length of contact I

page_text: provide a reversing gear for the purpose as follows: On the axis driving the rolls of
the machine I apply a larger and a smaller band pulley each having its appropriate
loose pulley and also at the end is applied a pinion gearing with another larger pinion
on a separate axis which larger pinion carries on a pinion eccentrically arranged a rod
which is connected to a bell cranked lever arm the other arm of the which operates a
bar or part having suitable stops or pieces which control the position of two driving
bands so as to place each alternately on its fast and loose driving pulley and so as to
transmit faster or slower motion to the axis of the machine as it is derived from the
driving axis to which motion is obtained from a steam engine or other suitable source
of power.

page_text: Coated Plates and in the Apparatus Employed therein.
I DAVID OWEN of Brookfield House Morriston near Swansea in the County of
Glamorgan Tin Plate Manufacturer do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
These improvements relate to the manufacture of tin and terne plates and such like
metal coated plates and the object of the invention is to economise the amount of
metal used in the tinning operation of tin plate to make the coatings of metal uniform
in terne plates to straighten the plates and otherwise to improve the results attained
or to better effect the greasing of metal coated plates without bending the plates by
the cradle in the grease pot.
In carrying out my invention I provide a vessel a for holding grease or flux into
which the plates in turn are passed between a pair of rollers bb or other number of
rollers may be used covered with felt or other suitable material. This grease or flux
containing chamber a is closed against escape of grease at the bottom by the molten
metal of the tinning pot c below into which the plates hence pass between a pair or
pairs of rollers dd dd into a cradle, frame, or guide way e capable of adjustment by
means of screws e¹ springs or equivalent means and by means of spring pressure such
as a spiral spring or springs the lower part of this frame is adapted to be depressed
by the incoming plate if required but in working with terne metal the greater density
thereof gives so much more buoyancy to the plate that the spring cradle is not
necessary and I have not shewn the springs and as soon as the rolls d d and d' d' aro
reversed and the plate released the plate is caused to be pressed up so as to be passed
out at about the point or into another vessel through rolls placed in position in a
box above that point similarly to the box a and provided with guide rolls as 6 contain-
ing a finer description of grease or other suitable matter.
In some cases I employ a preparatory bath of grease as at finto which the plates
are placed to soak or have prolonged contact with the grease or flux before entering
the first described chamber a and this may either be effected by hand or by an
automatic arrangement of finger levers or like gripping means and with releasing
parts as will be readily understood.
As it may sometimes be desirable that the entering motion for the tin plates into
the tinning pot c should be slower than the returning motion so as to give adequate
length of contact I in such case provide a reversing gear for the purpose as follows:-
On the axis g driving the wheel g¹ and by that wheel gearing with the wheel / driving
the wheels applied to the opposite ends of the rolls d d¹ and thereby the correspond-
ing rolls d d¹ thus the rolls of the machine are driven in unison and I apply a larger
band pulley j and a smaller band pulley k each having its appropriate loose pulley jrk¹
the pairs of band pulleys on the respective axes may be of substantially uniform size

page_text: and also at the end is applied a pinion gearing with another larger pinion 7 on a
separate axis which larger pinion carries on a pin & eccentrically arranged a
rod which is connected to one arm of a bell cranked lever arm 118, or this may be
effected by bevel wheels or other equivalent arrangement, for effecting a reversing
movement for inserting and removing the plates the other arm of which operates a
bar or part having suitable stops or pieces 18 which by grasp or engaging control
the position of two driving bands m. n so as to place each band m or n alternately on
its fast and loose driving pulley and so as to transmit faster or slower motion to the
axis g of the machine as it is derived from the main driving axis o to which motion is
obtained from a steam engine or other suitable source of power.

Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is:―
1. The combination or arrangement and use in apparatus for the manufacture of
tin and such like metal coated plates, of rollers as d'd, d¹ d¹, adapted to receive and
carry down plates to be tinned, or coated with terne metal, say from an upper grease
vessel containing delivery rollers covered with felt or similar material adapted to
facilitate the intimate application of the grease, and then by motion given to said
rolls dd, d'd' in the opposite direction to carry the plates up and out of that metal
that is to say, by the reverse motions of the same set or sets of rolls dd, d'd¹ to carry
the plates down into the coating metal and to return the same straight to the outlet
for further treatment as set forth.
2. I claim in apparatus for the manufacture of tin and such like plates rollers
arranged to receive and carry down such plates into grease or other matters in a
suitable vessel and by a reverse motion imparted thereto substantially as set forth of
removing and delivering the plates for further treatment or use.
