PHILIP ROGERS, Machinery Agent, 4 St. Georges Terrace, Hanover Street, Swansea,
and JOHN PLAYER, Tin-plate Manufacturer, Clydach, near Swansea in the County of
Glamorgan, do hereby declare the nature of this invention to be as follows:-
To perform with the Automatic Machine the several operations of immersing the
plates to be coated into the pot of molten metal or alloy, lifting the plates thence until
gripped by the pressing rollers, then when the plates have passed through the pressing
rollers moving them away and placing them on a rack, which rack holds them until
the coating metal has set and then deposits them on an inclined shelf, or on a carrier,
all of which operations have hitherto been done by hand, the advantage of using
the machine being a considerable saving in the cost of manufacturing Tin and Terne
plates &c., and fewer plates will be injured by careless handling; and each machine
will only require one un-skilled attendant to place the metal plates one by one on the
Cradle, in fact to feed it, the rest being done by the machine which delivers the
plates finished and ready for the cleaners.
The accompanying drawing will clearly show the action of the machine-Fig. 1 is
a front view of the machine with the front of the pot removed, Fig. 2 is a side
view with the rack and side of pot removed. The pot A is the usual vertical type
with a flux-box and an exit grease box B containing the pressing rollers G and G¹.
In the spur wheel e, which drives the rolls, is fixed a stud thus forming a disk
crank whose motion is communicated to the side lever shaft a by the connecting
rod d and the arm o. The side levers b and baro curved as shown and connected
to the Cradle H which is moved up and down as the wheel e revolves. The Cradle H
is composed of several vertical bars fixed to a horizontal bar which has a jaw at
each end working over the guide rods c which guide the bottom of the cradle in a
vertical plane as it is moved up and down, two of the vertical bars are hinged to the
side levers as shown and these and the radial ends of the side levers work outside and
clear of the flux-box C. The other bars of the Cradle which support the plates have
all their lower ends hooked as shown to catch the plates, the top ends of all but the
middle one are plain, and shorter than the middle one as shown, the top end of the

page_text: middle bar is turned over to form a projection to push down the plates which have a
tendency to float in the molten metal. It will be observed that when the cradle is up,
as shown dotted Fig. 2, it is in a convenient position to receive the plates as they are
passed on to it one by one through the fluxbox C.
To one side lever as shown are connected two chains or ropes S and S¹ equidistant
from its centre of motion, these are passed-round and secured-to the two small drums
on the shaft g but in opposite directions so that when the side lever 6 moves up and
down the shaft g partially rotates first one way then the other: the shaft g has a crank-
arm formed on each end but at right angles to each other, and fixed in the same frame
and similarly cranked is a shaft g', these cranks are connected on one side by the
rod p, and on the other by the rod m the bottom of which is formed into mechanical
fingers to grip the plates as they issue from the rolls G-this part of the machine,
collectively marked D, and including the standard F and the touch-rod i is called the
pick up"-the reason for having the shaft gl is to secure a steady parallel motion
for the fingers h. The crank-arms on which is fixed are so proportioned that h is
just suspended midway over the rollers when turned as shown by dotted lines in
Fig. 1, and midway over rack E as shown by full lines when turned the other way.
The fingers are made one fixed and one moveable and the lower ends are bevilled off
to form a guide to lead the edge of the plate into the grip, the moveable finger has a
projecting horn which serves two purposes-first its weight gives the necessary
gripping power to the fingers, and secondly as the fingers are swung over the rolls
this horn comes in contact with the touch-rod i which opens them ready to receive the
plate, when over the rack E the touch-rod releases the grip. The rack E is here
shown in a circular form (see enlarged view Fig. 3) and has the rods bent so that
only the points can touch the plates, on one side is formed a stud wheel with same
number of studs as spaces in the rack and between these studs is fixed a disk with
(preferably) four helical teeth, this disk is moved one tooth at a time by means of a
lever with ratchet and pawl which is worked by a chain or rope from the large drum
on shaft g, see enlarged view of disk Fig. 4.
The working of the machine is as follows-
:
The wheel e is revolved by power at the required speed and an attendant stands in
front opposite the flux-box C, when the cradle rises to about its highest position he
passes a pickled plate through the flux on to the cradle which by that time gradually
moves down immersing the plate in the coating metal, or alloy; the movement of the
cradle and the plate it carries is a compound one as it is gradually canted same time
so that when the cradle is at its lowest position the plate has been brought fairly
under the guide plates r leading to the rolls as seen in full lines Fig. 2, and this
compound motion is so easy that thin plates are canted through the dense molten
coating metal, or alloy, without buckling the cradle having reached its lowest point
of travel begins to rise and cant back to its former position, but the large surface of
the plate prevents its being moved easily in the dense molten metal or alloy except in
a vertical direction so the plate is raised until gripped by the pressing rolls G and
passed thence to G¹: as soon as the cradle has reached its top position another plate
is put on and the operations just described are repeated-we will now follow the course
of the first plate-the movement of the "pick up" is so timed that when a plate is
passed up and clear of the rolls G¹ the fingers h are waiting for it (as per dotted lines
Fig. 1) with the moveable one held open by the touch rod i, and the side lever b is
then as per dotted lines Fig. 2, the plate is then resting between the rolls G¹ and
supported by the fingers h, now immediately the side lever b begins to move down the
fingers h are raised (the shaft g being pulled round by the rope S) and the horn freed
from the touch-rod i, and the plate is gripped, and raised, and carried over the rack E
and lowered into a space between the rods, and when bottom edge of plate is near the
solid part of the rack the finger horn again comes in contact with the touch rod and
the plate is released and left in the rack, the fingers are now again swung over to
meet another plate being worked by the upward motion of side lever b, and while this
is taking place the ratchet lever on belical disk wheel of rack E is pulled up through
an angle of 90° by chain from large drum on shaft g, thus releasing one stud of rack

page_text: and leaving clear space for next plate when brought over by the pick-up. As the
rack is thus worked round it allows the plates to slide off on to an inclined shelf, if
not removed by cleaner, and piles one on the other without any injury, sufficient time
having elapsed since they were placed in the rack for the coating metal or alloy
to set.
Thus it can be understood that once the metal plates are placed on the cradle of
the machine all the other operations which hitherto have been performed by several
people and at considerable cost can now be done cheaply and efficiently by the
automatic machine which delivers the plates ready for cleaning.
Referring to the drawing-the fingers h have a horizontal wing piece on each side
to prevent the plate canting in its grip. The standard F has holes at different
heights to adjust the pick up for different sizes of plates, and further adjustment is
made by substituting cradles of different lengths, and by altering the timing of the
machine at wheel e. As shown in drawing all is arranged for the ordinary size
plate 20 inches by 14 inches. The guide rods c are shown curved at the top ends in
Fig. 2, this is done to facilitate the withdrawal and replacing of the cradles without
disturbing the metal in the pot.

We, PHILIP ROGERS, of 1, St. George's Terrace, Hanover Street, Swansea,
Machinery Agent, and JOHN PLAYER, of Clydach, near Swansea, Tin Plate
Manufacturer, in the County of Glamorgan, 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
This invention has for its object to provide a machine that will perform mechanically
the different operations necessary for the coating of tin and terne plates and the like,
which operations have been heretofore performed by hand, the advantage gained by
using such a machine being a considerable saving in the cost of production, a
reduction in the number of plates injured by careless handling during the operations,
and saving of labour as each machine can be worked by one attendant. The
operations necessary to be performed by such a machine comprise immersing the
plates to be coated into the pot of molten metal, lifting the plates thenco until gripped
by the pressing rollers, then when the plates have passed through the pressing rollers
moving them away and placing them on a rack, which rack holds them until the
coating metal has set, and then deposits them in a pile on an inclined shelf, or on a
carrier, or otherwise disposes of them.
A machine constructed in accordance with this invention comprises a pot for molten
metal over which is fixed a box containing grease in which one or more pairs of
rollers are worked for pressing the plates after they come out of the metal, a flux
box through which the plates are passed into the molten metal, a cradle which receives
the plates through the flux box and which carries them down into the metal and then
delivers them upwards through the grease box to the pressing rolls, a pick-up"
apparatus which is designed to take the plates as they leave the rolls and to deposit
them in a rack or otherwise, and a rack or other suitable receptacle into which the
. plates are put.
Referring to the drawings filed with our Provisional Specification,
"
Figs. 1 and 2 illustrate the construction and arrangement of a machine or apparatus
made according to this invention, in which
Fig. 1 is a front view of the machine with the front of the pot removed, and
Fig. 2 is a side view with the rack and side of pot removed. The pot A is of the
usual vertical type with a flux-box Cand an exit grease box B containing the pressing
rollers G and G. In the spur wheel e, which drives the rolls, is fixel a stud forming
a disc crank by which reciprocal motion is communicated to the side lever shaft a by
the connecting rod d and the arm o. The side levers and are curved as shown

page_text: and connected to the cradle H which is moved up and down as the wheel e revolves.
The cradle H is composed of several vertical bars fixed to a horizontal bar which has
a slot at each end working over the guide rods c which guide the bottom of the cradle
in a vertical plane as it is moved up and down, two of the vertical rods are hinged to
the side levers as shown the side levers work outside and clear of the flux-box C. The
other bars of the cradle, which support the plates, have all their lower ends hooked, as
shown, to catch the plates; the top ends of all but the middle one are straight and shorter
than the middle one as shown; the top end of the middle bar is turned over to form
a projection to push down the plates which have a tendency to float in the molten
metal. It will be observed that when the cradle is up as shown dotted in Fig. 2, it is
in a convenient position to receive the plates as they are passed on to it one at a time
through the flux-box (. To one side lever bare connected two chains or ropes S
and S equidistant from its centre of motion; these are passed round and secured to
the two small drums on the shaft g but in opposite directions so that when the side
lever moves up and down the shaft g partially rotates first one way then the other;
the shaft g has a crank-arm formed at each end but the said crank arms are at right
angles to each other and fixed in the same frame and similarly cranked is a shaft g¹ ;
these cranks are connected on one side by the rod p, and on the other by the rod m,
the bottom of which is formed into mechanical fingers to grip the plates as they
issue from the rolls G¹.-This part of the machine collectively marked D and including
the standard and the touch-rod i is called the "pick-up."-The reason for having
the shaft Gis to secure a steady parallel motion for the fingers h. The crank arms
on which his fixed are so proportioned that his just suspended inidway over the
rollers when turned as shown by dotted lines in Fig. 1 and midway over rack E (to
The
be described further on) as shown by full lines when turned the other way.
fingers are formed so that one is fixed and the other is hinged and movable and the
lower ends are bevilled off to form a guide to lead the edge of the plate into the grip;
the movable finger has a projecting horn which serves two purposes-first, its weight
gives the necessary gripping power to the fingers to enable the grip to hold the plate
and secondly, as the fingers are swung over the rolls this horn comes in contact with
the touch-rod i which opens them ready to receive the plate. When over the rack E
the touch-rod releases the grip so that the plate falls into its place in the rack. Tho
rack E is circular in form as will be seen in the enlarged view Fig. 3 and has the
rods bent so that only the points can touch the plate. On one side is formed a stud
wheel with the same number of studs as there are spaces in the rack, and upon the
stand supporting the rack and so placed as to pass between these studs is fixed a
disc with preferably four helical teeth, (Fig. 4); this disk is mooved one tooth at a
time by means of a lever with ratchet and pawl which is worked by a chain or rope
from the large drum on shaft G.
We will now describe the working of the machine. The pot A is filled with metal
so that the openings of the grease-box B and Flux box Care sealed; Grease is placed
in B, Fluxing material in C. The machine is adjusted for the size of plates to be
coated. When the machine is started the attendant passes a plate already pickled
into the Flux box C through the fluxing material on to the cradle H; this is done
while the cradle is in its top position. The cradle is now moved down by the
levers b, ; the movement of the cradle is a compound one, the bottom being guided
in a vertical plane by guide rods c, while the top is canted back during the downward
movement so that in its lowest position the top edge of the plate is brought fairly under
the rolls G; having reached its lowest point of travel the cradle begins its upward
movement and in rising cants forward, but the large surface of the plate prevents its
being moved easily through the molten metal in any but a vertical direction so that it
does not cant forward again with the cradle but is raised by it until the top edge is
passed into the grip of the rolls G; thence it travels to rolls G¹ and is rolled up until
free. By the time the plate has been rolled free from rolls G¹, G', the fingers h have
been swung over and the horn coming in contact with i has opened them allowing
the plate to pass freely into the nip; immediately begins to lift, the horn is released
from i, and the plate is gripped; it is then swung over by the action of the cranked

page_text: arms into a space between rods of rack E, then the horn comes in contact with the
second touch rod and releases the plate which falls into the rack E; the fingers are
then swung back to fetch another plate. While this is taking place the ratchet lever
on helical disc wheel of rack E is pulled up through an angle of 90° by the chain or
cord from large drum on shaft g thus releasing one stud of the rack d leaving a fresh
space for the next plate to fall into when brought over by the pick up. As the rack
is thus worked round it allows the plates to slide off on to an inclined shelf, and (if,
they are not removed by the cleaners), they are then piled one on another without any
injury, sufficient time having elapsed since they were placed in the rack for the coating
metal, or alloy, to set.
Figs. 1 and 2 of the sheet of drawings annexed hereto illustrate a machine con-
structed in accordance with this invention according to a modification and Figs. 3
and 3 of the same drawings illustrate a further modification, which is designed
specially for use when plates larger than ordinary have to be coated or tinned.
The same letters of reference refer to similar parts in Figs. 1 and 2 of these
drawings.
Fig. 1. is a front view of the machine with the metal pot and flux box in section;
Fig. 2 is a side view of same with rack removed and the metal pot and flux box,
and part of the grease box in section.
The shaft I is driven by power and transmits motion to the rolls G¹ and G by the
gear wheel, and to the crank-shaft e by the gear wheels h, g, f,-On the ends of the
shaft a are fixed the side levers b, b', one of which, b, is connected to the crank e by
the connecting rod d. The curved ends of the levers b, 61, are jointed to the outside
bars of the cradle H. The bottom end of the cradle H is held in position by lugs
sliding on guide rods c fixed in the pot A. One or more bars of the cradle, (preferably
two, as shown,) are made longer than the others and are turned over to form a short
projection. The clips v are placed on two short bars and are capable of adjustment,
so as to shorten or lengthen the distance from the projecting ends of the long cradle
bars. On the back of the pot A are cast projecting ribs M. In the grease-box B are
placed the finishing rolls G and G¹; under the rolls G is a guide box I; and under the
rolls G₁ are roll-feeding-troughs K fitted with guides as shewn. The apparatus for
removing the coated plates and which we may call the "Pick-up" is collectively
marked D and comprises a standard carrying a lever pivotted at c, shafts m and m².
At one end is connected to the crank e by a jointed connecting rod d¹ and the
adjustable crank e¹ is secured to crank shaft e by a tightening bolt as shewn, giving
motion to lever r, a toothed segment on the other end of lever which gears into
toothed wheels which is secured to shaft m'. To the shafts m and m' are secured, in
front, the crank arms which carry the connecting rod o, and at the back the crank
arms connected by rod p; these two sets of arms being fixed at right angles to one
another secure a steady parallel movement for the rod o to which are fixed the
mechanical fingers n so as to be capable of adjustment in a vertical direction. The
fingers n of which we preferably employ two pairs, as shewn in fig. 1 are made to act
simultaneously by being connected and are provided with a weight or spring or a
combination of both to give sufficient power to hold firmly the heaviest plates the
machine has to work. The projecting horn of the fingers n as shewn is in contact
with touch rod k. Over the rack E (to be presently described) is another touch rod k¹;
both the touch rods are capable of being adjusted in a vertical direction by any
suitable means.
The rack E can be arranged on an endless belt, or by preference may be of a circular
form as shewn, and may be advantageously made by casting a disc of iron around
rods already curved or bent so as to present few points of contact with the plates.
Two of these discs with rods are secured on the rack shaft and the space between is
filled in with wood lagging, or battening, to a slightly larger diameter than the iron
discs, in order to present a large bearing surface to the edges of falling plates, and
thus to prevent damaging the edges. Fig. shews a side view of a part of a rack
disc and rods. In the arrangement Fig. 1 the outer end of the rack shaft is supported
by a vertical stay and the inner end by the hob-plate, near which is fixed on the shaft

page_text: a worm wheel s¹ into which gears a worm supported by brackets screwed on the hob-
plate; On this worm shaft is a small sheave t¹ connected by a chain to sheave t fixed
on shaft m. A short length of chain with a balance weight is also attached to t¹
which runs loose upon the worm shaft one way but moves it in one direction by means
of any suitable arrangement of side cam sheave (a suitable form of side cam sheave
will be described hereafter) or ratchet and pawl; we use the former.
When working large plates we place a V shaped guide over top pair of rolls near
the tooth wheel to prevent them falling over until supported by the finger guides.
When the machine is working the roll feeding troughs K are kept full of metal,
and they may be placed under the top or the bottom pairs of rolls, or under both;
and when three or more pairs of rolls are used they may be placed under all or any
of them according to the quality of plates required. We find by using these Troughs
we get a better and more perfect coating on the plates.
On the cradle clip fig. 2 is shewn a spring; this is used when working "Terne"
because at the moment after the cradle has reached its lowest point of travel and
before the return movement commences it would allow the plate to float unless pre-
vented by some such device. As it is essential that the machine work smoothly, all
moving parts not in equilibrium are furnished with suitable counter-balance weights as
shown by Z. The machine inay be adjusted to take different sized plates by altering
the distance between the hooks v and the top of the long cradle bars, then the lugs
that slide over the guide rods c are placed in holes nearest in line to bottom edge of
plate, next a change wheel is fixed that will just roll up the length required and the
intermediate wheel g is geared in. The fingers of the "Pick up are then adjusted
to the height, the touch rods put to suit them, the crank e¹ is then shifted to a position
that will allow the fingers to lift away the plate immediately it is free of the rolls so
as not to leave a list on bottom edge.
Fig. 3 of the drawings annexed hereto illustrates a modification of the cradle
specially adapted for working plates of large size. The guide bars c which are formed
preferably of flat iron, are made double at the bottom to form a guide for the cross
bar d long enough for the full stroke of side levers b; these bars are rivetted at their
bottom ends to a bar n which extends the full width of the pot A and enters into
notches as shown in the drawings, the advantage of this construction is that should it
be necessary to remove the guide bars when the pot is full of metal it is very easy to
slip them back into place again. The top ends of the guide bars are secured to the
front of grease-box B by studs as shewn. Just below the flux box Care side guide
plates g more clearly shown in fig. 3 the same distance apart as the inside of C;
they are turned over at the top to give easy entrance to plates. The cradle H is hinged
at on the front edge of the pot A and is composed of the same number of bars
(bent as shewn) as there are ribs M formed at back of the pot A; these bars are kept
together by being rivetted to the cross bars p, i, o, the ends of i are extended
beyond the bars on each side to form a hinge in the lugs as shewn, and the
ends of o are extended far enough on each side to come in contact with
guide plates g and so prevent the free end of the cradle when it floats in the
metal from advancing nearer to ribs M than is shewn. Under the guide box I
a bar works in holes in guide plates g (see Fig. 3) and to this bar are rivetted
as many guide bars m as there are bars in the cradle, and the ends of these guides m
aro pressed against H by the action of the floats S one of which is fixed at each end
of bar. The ends of m are carefully seated in notches formed in bars H. The side
levers are connected to cross bar d by connecting rods and on d in the spaces
between cradle bars H are fixed clips e furnished with springs, or with clips worked
by a float as shown in Fig. 4. The working of this arrangement is as follows.-The
plate to be coated is passed into flux box C through the fluxing material and when
cross bar d is at its highest point its lower edge is pushed into the clips e; the plato
in going down moves back the fingers m which immediately return to their places
when the top edge of plate has been drawn below them.-As the plate is moved up it
can only pass up into guide box 1 and thence to the rolls. This arrangement is also
most convenient for extracting a damaged plate.

page_text: Fig. 6 is a modified arrangement of the "Pick-up" which dispenses with the
necessity of a rack.
a,
On a vertical shaft a is fixed a circular casting formed as seen in section 6 on which
are arranged a number of levers c and c¹ having fingers n at outer end and a balance
weight d sufficient to more than counterbalance the weight n when loaded with the
heaviest plate to be worked. There should preferably be an even number of fingers
to act opposite to each other in pairs as indicated in the sketch. Fitting loosly on
the shaft is a sleeve e from the bottom of which project two narrow lugs one oppo-
site the other as shewn under weights d, the top part of the sleeve is secured in the
fork of a lever and so kept from turning; f is pivotted on a swing bar h which is
pinned to the stay g the outer end of which supports the shaft a on the end of which
is fixed a worm or ratchet wheel i. The bottom end of shaft a, according to this
arrangement, would be seated in a step on the hob plate where the rack shaft
bearing (Fig. 1) is shewn that is to say in the same vertical line as the nip of the
rolls; instead of crank e¹ (fig. 1) two face-cams are placed on crank shaft e, (fig. 1)
each cam to work a horizontal vibrating lever fitted with a friction wheel to work on
the face of the cam, as seen in Fig. 6 at x.
The back end of each of these levers is pivotted to the top of the grease pot, the
friction wheels are fixed about the middle of the levers, and the end of one is connected
by a chain or rod to the eye of lever and the end of the other is connected similarly
to a ratchet, or side cam sheave, on a worm shaft (working into wheel i,) fixed on
the stay overhanging the end of its vibrating lever. The detail of this arrangement
is shown in Fig. 6 at y, and also in detail in Fig. 6°. y (Fig. 6) is a cam sheave
having a sliding motion upon the spindle which carries at its other extremity a worm
working into the worm-wheel i. The cam sheave is pressed forward in the direction
of by a light spring y²; it is so constructed with a step seen at 6 (Fig. 6) that,
when moving in one direction, it engages with a pin in the spindle ; but, when
turned in the opposite direction, the step 6 (Fig. 6) passes the pin (by the momentary
compression of the spring y2) so that the spindle is actuated only in one direction.
Sufficient friction is given to the spindle to prevent its turning with the backward
motion of the cam sheave y by a stiff spring working against a washer behind the
springy which presses the spindle firmly into its bearing at the end i. These cams
are so timed that as soon as a plate is free of the rolls G¹ the fingers over it will be
depressed by means of the cam acting through its connection and lifting the sleeve e
and consequently raising the weights d, and opening the fingers to take in the plate,
by contact with touch rod k as explained in connection with the first arrangement.
The.action is immediately reversed by lowering the sleeve e whereby fingers / are
released from the touch rod and grip the plate holding it in the position shown. The
second cam now comes into play and through its connections and wheel it turns
shaft a so as to bring the next pair of fingers over rolls, and so on-by the time the
first pair of fingers carrying a plate in their grip come opposite to the pair of fingers
being depressed to take up a plate, they will be also depressed, that is both pairs or
sets of fingers will be simultaneously depressed and the plate will be released by the
touch rod disengaging the fingers. The plate may thus be dropped on to a shelf ready
for the cleaners, or it may be placed on a carrier or otherwise disposed of as may be
desired.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
