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:-
:―
This invention has reference to further developements of the apparatus for the
manufacture of tin and terne plates and such like coated metal plates described in the
Complete Specification left by me at the Patent Office in pursuance of my application
for Patent No. 8966 dated the 9th July 1886.
In the said Specification I have described and shown pairs of superposed rollers
which by means of rotations given them in one direction take hold of and carry down
the plates into tin or terne metal or other matters below and then by rotations given
to the same rollers in a reverse direction to retire the plates and carry them up out of
the matters and at the same time promoting by the pressure of these rollers the intimate
and even application of matters applied to the plates.
According to the present invention I arrange sets of such rollers three or more in a
row or set and in one row or two or more rows superposed; so as to enable plates
especially small ones to be more rapidly treated and with better effect or to be more
evenly coated or surfaced. In the use of rollers thus arranged economy of power
results from the middle rollers serving for double duty the one side acting with its
adjacent roll to enter a plate whilst the other side is acting with its adjacent roll to
withdraw a plate.
The rollers are kept pressed towards each other by suitable adjustable spring
leverage.

page_text: Improvements in the Manufacture of Tin and such like Metal
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 performned, to be particularly described and
ascertained in and by the following statement :-
These improvements relate to certain modifications in the arrangements of the means
or apparatus employed in the manufacture of tin plates and other plates similarly
coated with metal as described in the Specification of Letters Patent granted to me
bearing date the 9th day of July 1886 and numbered 8966.
According to my present invention I arrange two or more sets of rolls between the
impinging peripheral surfaces of which the plates pass in and out to and from the
molten tinning metal in the pot in which are arranged one below each passage way
between the rollers, cradles, frames or guides which may be made adjustable by means
of screws or otherwise to adjust themselves or be adjusted to the plates. The grease
box, or flux chamber, or double, or other number of divisions, or chambers of flux, and
grease, is made capable of traversing over the tinning pot rollers so as to present
itself alternately over one and then another or the other of the entrances to the pot
supported and guided by suitable framing and cranked arms, links and actuated by
gearing adapted in reversing to vary the position of grease or flux receptacle whilst
the speeds relatively of the rollers in inserting and withdrawing the plates is also
varied. The tinning rolls are also arranged in superposed sets so that the inner
rolls may do double duty on one side in inserting plates and on the other in with-
drawing plates.
A soaking or preparatory grease pot adapted to give prolonged contact of grease to
the plates before entry may be arranged contiguous to the tinning pot and the plates
manipulated by hand labour or mechanical grips.
By such arrangement of sets of rollers three or more in a row or set and in one row
or two or more rows superposed it enables plates especially small ones to be more
rapidly treated and with better effect.or to be more evenly coated or surfaced.
In the
use of rollers thus arranged economy of power results from the middle rollers serving
for double duty the one side acting with its adjacent roll to enter a plate whilst the
other side is acting with its adjacent roll to withdraw a plate.
The rollers may be kept pressed towards each other by suitable adjustable spring
leverage.

page_text: Figure 3 shews a method of arranging spring pressure to a double set of rolls;
separately.
a, a', a², are upper rolls b, 61, 2 lower rolls. c, c¹, c², care gear wheels mounted on
the axes 1, 2, 3, 4 at one side of the pot and c', c³, co are other three toothed gear wheels
mounted respectively on the axes 5, 4, 6 at the other side of the pot d. e is a cradle
into which the plates are received from and from which they are passed out to the rolls
above them successively.
f is a flux box through which the plates pass to the nip of the rolls a¹, a², or a, a¹
accordingly as the box fis over one or other pair and as the plate passes in clear of the
box the box passes to the other opening or nip say a-a' and the same motion of
roll a', that acting with roll a² is bringing out a plate, is acting with the roll a to
introduce a plate and the lower rolls b, 6, 63 act correspondingly with their counter
part rolls directly over them.
The driving of these rolls and the corresponding movement of the flux box fis
effected as follows:-
9 is a main driving axis having mounted on it the larger and smaller drums g¹, 92
which by bands g³, g* drive respectively the fast and loose pullies h, h¹ and fast and
loose pullies i, each respectively mounted, fast or loose, on the axis (1) and on the
other end of the axis (1) opposite to the rolls is mounted the gear wheel (7) which
engages the larger gear wheel (8) which is mounted on a short axis (9) carried in a
bearing (10) suitably supported. Excentrically of the wheel (8) is a short stud or
arm (11) which has attached to it one end of a link rod (12) the other end of which is
connected to the crank arm (13) centred at (14) on a pin carried by a suitable support.
The other arm (15) of this crank arm is hinged to the slide plate (16) sliding in
guides (17) and (18), and this slide (16) carries pins (19) which between them hold
the bands g³, g and the movement of these pins moves these bands off or on their fast
and loose pullies--the band g³ being on its loose pulley and the band g on its fast
pulley, as shewn in the drawing, so that the rolls are rotating in the directions indicated
by the arrows and the rolls a¹, a², b, 62 are entering a plate coming in through the
flux box whilst the rolls a, a, b, b1 (the rolls a¹, I always doing double duty on one
side with a, b and on the other side with a², 62 respectively) and by reason of the link
arm (20) being connected to the arm of the crank at (15) and at its opposite end to
the link (27) and these two links being connected to the two bell crank arms (25, 26)
centred to the pot side at (21, 21) which cranks being linked by parallel links (22, 22)
to the projections (23, 24) from the flux potf any reciprocating rotatory motions given
to the rolls by the alternate transfer of the bands 93, 91, is productive of motion
reciprocatively to the flux box f to bring it over the rolls for the time being entering
the plates.
The flux box may have side divisions, f for holding grease when the middle
division holds flux.
I have not thought it necessary to shew the means of applying spring pressure in
Figure 1, in order to simplify comprehension of the invention. In Figure 3 I have
indicated a method of applying pressure to the bearings a³ of the rollers by means of a
spring lever centred at land pressing at one end on those bearings and at the other
end pressed outward from the framing carrying the rolls by means of an adjustable
screw working in a thread working in that end of that lever but any ordinary or
suitable method of applying such pressure may be employed as will be obvious to any
mechanic acquainted with this class of machine.
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 :-
In apparatus for manufacturing tin, and like metal, coated plates the arrangement or
combination and use of
1. A tinning or grease pot having rolls arranged in two or other number of series
so that plates may be capable of introduction and expulsion at the same time, by one

page_text: motion of a central roll or central rolls, acting with other rolls, placed on either side of
and geared to act with the central roll or rolls.
2. A tinning, or molten metal or grease pot having rolls arranged for the central
roll or central rolls to do double duty by cooperation with the side rolls as described,
and a movable flux box f geared to act, as described, to come into position over the
rolls when in motion for entry of plates, all substantially as set forth.
3. A tinning or grease pot, with rolls cöoperating and actuated, as described, a
movable grease and flux box, or a flux box, operated correspondingly to the motion of
the rolls, with means for soaking the plates, all substantially as set forth.
