Metal Plates with Tin, Terne, or other Metals or Alloys.
I DAVID DAVIS of Beaufort Iron and Tin Plate Works, Morriston in the County
of Glamorgan, Iron and Tin Plate Manufacturer do hereby declare the nature of the
said Invention to be as follows:-
:-
The Invention relates to that part of the process of coating metal plates wherein
the plates after having been dipped into the molten metal or alloy are passed
between rolls arranged in a "grease pot" for the purpose of evenly distributing
the molten metal over the surface of the plate and for removing surplus metal
therefrom.
In carrying my invention into effect I arrange two groups of rolls and their
connections within one "grease pot," and I employ only two pairs of rolls in each
group and instead of passing the plate downwards between two pairs rolls and
then upwards between another pair, I first conduct the plates directly and without
passing through any rolls on to a cradle arranged within the "grease pot," when
the plates are tilted forward by "fingers" as heretofore into position to be taken
by the rolls, and I then pass them upwards between the two pairs of rolls.
A cradle is provided for each group of rolls and it is mounted in such a manner
that it is capable of being slightly raised to place the plate within the grip of the '
first pair of rolls.
The two cradles are connected by rods to a rocking bar which is operated by
means of a lever to alternately raise and lower each cradle or they are otherwise
connected so that one operative can with ease keep the two groups of rolls fully
employed.
By the aid of my invention I obtain an increased out-put of tin plates and a
saving in the consumption of tin as there is less oxidation in addition to which
I also obtain a saving in palm oil and fuel.

I DAVID DAVIS of Beaufort Iron and Tin Plate Works, Morriston, in the County
of Glamorgan, Iron and 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:-
"
The invention relates to that part of the process of coating metal plates wherein
the plates after having been dipped into the molten metal or alloy are passed
between rolls arranged in a grease pot" for the purpose of evenly distributing
the molten metal over the surface of the plate and for removing surplus metal
therefrom.
In carrying my invention into effect I arrange two groups of rolls and their
connections within one "grease pot" and I employ only two pairs of rolls in each
group and instead of passing the plate downwards between one pair of rolls and
then upwards between two pairs, I first conduct the plates directly and without
passing through any rolls, on to a cradle arranged within the "grease pot," when
the plates are tilted forward by "fingers" automatically into position to be taken
by the rolls, and I then pass them upwards between the two pairs of rolls.
A cradle is provided for each group of rolls, and it is mounted in such a manner
that it is capable of being slightly raised to place the plate within the grip of the
first pair of rolls.
The two cradles are connected by rods to a rocking bar which is operated by
means of a lever to alternately raise and lower each cradle or they are otherwise
connected so that one operative can with ease keep the two groups of rolls fully
employed.
And in order that my said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully
Figure 1 is a vertical section drawn on the line A, B, of Figure 2 of means or
apparatus constructed according to my invention and Figure 2 is a plan of the
same.
My invention relates to that part of the process of coating metal plates wherein
the plates after having been dipped into the molten metal or alloy are passed
between rolls arranged in a "grease pot" for the purpose of evenly distributing
the molten metal over the surface of the plate and for removing the surplus metal
therefrom.
In carrying my invention into effect I arrange two groups of rolls b, b¹, c, c¹, and
their connections within one "grease pot" a and I employ only two pairs of rolls in
each group and instead of as heretofore passing the plate downwards between one
pair of rolls and then upwards between two pairs I first conduct the plates directly

and without passing through any rolls on to a cradle d arranged within the
grease pot "when the plates are tilted forward by "fingers "e automatically by
balance weights e' into position to be taken by the rolls.
A cradle d is provided to act in combination with each group of rolls and it is
mounted on guide rods fin such manner that it is capable of being slightly raised
for the purpose of placing the plate within the grip of the first or lower pair
of rolls.
The two cradles d, d, are connected by rods g, g, to a rocking bar or lever h¹ fixed
to an axis h which is operated by a lever h' fixed thereon to alternately raise and
lower each cradle d so that as one cradle is being raised to bring a plate into the
grip of the rolls, the other is being lowered in readiness to receive a fresh plate
whereby one operative can with ease keep the two groups of rolls fully employed.
Or the cradles & may be otherwise connected and still effect the same object.
The rolls bb and c, c¹, are geared together respectively at one end by
pinions 63, c³, and the rolls b and c¹ are geared together at the other end by
toothed wheels 63 c³, and motion is given to both sets of rolls by means of toothed
gearing giving motion to the toothed wheels c³ c³ and driven by a common shaft.
Simultaneous rotary motion may however be given to both sets of rolls by any
suitable means.
By the aid of my invention I obtain an increased output of tin plates and a
saving in the consumption of tin as there is less oxidation in proportion to the
number of plates treated in addition to which I also obtain a saving in palm oil
and fuel.
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:-
The combination with a "grease pot" of two groups of rolls, consisting of two
pairs each, two cradles and two sets of fingers all arranged and operated in manner
substantially as herein shown and described and for the purpose stated.
DAVID DAVIS.
