PROVISIONAL ST MOITIATION
Improvements in Apparatus used in the Manufacture of Tin Terne
and other Coated Metal Plates.
1. DANIEL EDWARDS, of Dyffryn Steel and Tin Plate Works, Morriston, in
the County of Glamorgan, Tin Plate Manufacturer, do hereby declare the nature of
this invention to be as follows:-
The object of this invention is to provide mechanical appliances by which tin
terne or other coated metal plates as they rise up from the oil or flux bath at the
exit of the coating bath may be automatically taken and delivered into a
travelling rack to cool, previous to being taken away by girls to be cleaned or
branned.
To effect this I cause the upper edge of each plate as the plate rises up from the
delivery rolls in the oil or flux bath to rise up between the jaws of a clip. At this
time the jaws of the clip are held open. The clip is carried at one end of an arm
which at the time when a plate is entering into it is in approximately a horizontal
position. Through the opposite end of the arm passes an axis which is parallel
with the rolls and is driven continuously. As the upper edge of the plate rises up
into the clip it is made to come against the under side of the end of a lever which
is mounted at the side of the arm. As the lever is lifted by the plate it liberates a
clutch lever and allows it to come against a latch which is also carried by the arm
and cause it to engage with teeth or notches formed around the circumference of a
wheel which is fast on the continuously travelling axis above mentioned. The arm
is so made fast with the axis and is at once carried upwards by its rotation.
Immediately after the arm is so made to commence to travel upwards the movable
jaw of the clip which as above stated was before held away from the fixed jaw is
allowed to close and so grip the plate and carry it along with it the clip being
caused to travel at the same speed as the plate is delivered from the rolls.
To allow of the movable jaw being at this time so allowed to close, a tail end of
the movable jaw may by the movement of the arm which carries the clip be
carried past a fixed stop against which it was previously resting and the
movable jaw be then moved towards the fixed jaw by the action of a spring or
weight.
As the axis revolves and when the clip arm and plate have been carried round to
its opposite side the end of the plate held by the clip enters between rods which
stand up from a horizontal endless chain and form a rack into which the plates are
to be deposited. The tail end of the clip is now brought against a fixed stop and
the clip thereby opened, and leaves the plate in the rack-the clip arm being still
carried round with the continuously rotating axis until the latch which locks it to
the wheel on the axis is disengaged from the wheel.
Preferably I arrange this to take place about at the time when the clip arm is
hanging vertically below the axis-and I provide a pair of such clip arms upon
the axis to come into action alternately one to be brought into position to
receive a plate from the rolls whilst the other is conveying away a plate to
the rack.
In order to lock each clip arm to the axis and liberate it at the required time I
arrange the latches which lock them to the toothed wheel on the axis to be
normally pressed outwards away from the wheel by the action of a spring or
weight. When the latch is to be made to engage with the wheel I allow it to be
pressed towards the wheel as above stated by a clutch lever this lever is carried by
a fixed fulcrum and is acted on by a spring or weight. When the latch has been
so made to engage with the wheel it is kept engaging with it by a fixed ring which

page_text: closely encircles the circumference of the wheel and the ring the latch engaging
with the wheel until by the rotation of the axis the latch has been carried round to a
point where a notch has been formed in the ring which allows the latch to be
withdrawn by the action of a spring or weight. The arm then remains for a time
at rest until the latch is again pressed inwards towards the wheel by the action of
the clutch lever above mentioned.
This clutch lever is forced back and kept out of action by pins on the levers
which are mounted at the sides of the clip arms. Each time that one of the clip
arms is locked to the axis and made to travel from its vertical position of rest to
its horizontal position the pin carried by the lever at the side of this arm comes
against the clutch lever and forces it back and holds it out of action until a plate
has risen up into the clip of this arm and lifted the lever as hereinbefore described.
The lifting of the lever raises the pin (which projects from it) above the top of the
clutch lever and so allows this lever to be turned a distance by the spring or weight
which acts upon it. As the lever is so turned it acts against the latches both of
the clip arm which is in the horizontal position and the clip arm which is in the
vertical position and so locks both arms simultaneously to the axis.
When a plate has been delivered into one compartment of the rack which stands
up from the horizontal endless chain above mentioned the chain is made to travel
a distance to bring the next compartment of the rack into position to receive a
plate.
To give this motion to the endless chain at the proper time a pin standing out
from the side of the clip arm may be caused to come against a lever which is
connected by a link with a crank lever which by another link gives motion to a
crank lever which turns around an axis concentric with one of the two wheels by
which the endless chain is carried. An arm of this lever carries a catch in such a
position that when the lever is turned the catch comes against a portion of the
rack and carries the rack and endless chain around with it.
A spring or weight is used to afterwards bring back the levers to their
normal position the catch on the crank lever above mentioned then giving way
freely.
The plates placed into the compartments of the endless travelling rack may be
automatically discharged from them at any desired point if they have not been
previously taken from them by hand.
To do this each compartment of the rack may be hinged to the chain so that
instead of standing up from the chain it may turn downwards. The weight of the
plates in the compartments may be made to tend to give this downward movement
to the racks and the racks be prevented from turning down until the desired point
for discharging is reached by arms on the racks coming below a fixed bar or plate-
so that when the racks have travelled past this bar or plate they drop. A fixed
inclined guide may subsequently be caused to bring back the racks into their
normal vertical position.
Other means than those above described may be used for giving motion to the
endless chain or for conveying away the plates as they are delivered from the clip
arms.
In some cases two sets of narrow plates are delivered alternately from opposite
ends of the finishing rolls. In this case a double set of clip arms would be
provided one set on each side of the toothed wheel which is fast on the axis-
and these would come into action alternately-first a clip arm on one side of the
wheel would receive a plate from the rolls and then a clip arm on the opposite side
of the wheel would receive a plate and so on. The racks carried by the endless
chain would be made double-one to receive plates from one set of arms and the
other to receive plates from the other set.
Dated this Third day of January 1891.

Improvements in Apparatus used in the Manufacture of Tin Terne
and other Coated Metal Plates.
I, DANIEL EDWARDS, of Dyffryn Steel and Tin Plate Works, Morriston, 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 :-
The object of this invention is to provide mechanical appliances by which tin
terne or other coated metal plates as they rise up from the oil or flux bath at the
exit of the coating bath may be automatically taken and delivered into a
travelling rack to cool, previous to being taken away by girls to be cleaned or
branned.
To effect this I cause the upper edge of each plate as the plate rises up from the
delivery rolls in the oil or flux bath to rise up between the jaws of a clip. At this
time the jaws of the clip are held open. The clip is carried at one end of an arm
which at the time when a plate is entering into it is in approximately a horizontal
position.
Through the opposite end of the arm passes an axis which is parallel with the
rolls and is driven continuously. As the upper edge of the plate rises up into
the clip it is made to come against the under side of the end of a lever which
moves a latch and other parts carried by the arm. The latch is thereby caused to
engage with teeth or notches formed around the circumference of a wheel which is
fast on the continuously travelling axis above mentioned. The arm is so made
fast with the axis and is at once carried upwards by its rotation. Immediately
after the arm is so made to commence to travel upwards the clip is allowed to grip
the plate and carry it along with it.
As the axis revolves and when the clip arm and plate have been carried
over to its opposite side of the axis the end of the plate held by the clip enters a
rack and a finger on the clip arm coming against a stop causes the clip to open and
release the plate. The clip arm after releasing the plate passes on, is still carried
round with the continuously rotating axis the latch being kept engaged with the
wheel by a fixed guide ring which closely encircles it. There is however a notch
in the ring which at a suitable point allows the latch to escape and then the arm
comes to rest and waits until the latch is again put into gear. I provide two or
more clip arms to follow each other in succession around the axis and immediately
one has received a plate from the rolls another advances to the receiving position.
The arm standing in the receiving position prevents a filling piece from occupying
that notch in the guide ring which arrests the following arm. Similarly this
second arm (if three arms be employed) controls the filling piece for another notch
in rear.
The notches serve as stopping stations for the clip arms but only so long
as they are unoccupied by filling pieces.
The receiving rack consists of a series of plate carriers with pins upon them.
These carriers are connected by an endless chain and they are supported by rollers
which run along a guide course.
When a plate has been delivered into one compartment of the rack the chain is
made to travel a distance to bring the next compartment of the rack into position
to receive a plate.
To give this motion to the endless chain at the proper time a pin standing out
from the side of the clip arm comes against a lever and puts a rack in gear with a
constantly revolving pinion. The toothed rack when thus noved advances the
series of carriers. When the toothed rack gets to the end of its course it drops out
gear and a spring causes it to return.
of
The plates placed into the compartments of the endless travelling rack may be

page_text: automatically discharged from them at any desired point if they have not been
previously taken from them by hand.
To do this each carrier is hinged to the chain and it falls outwards at a place
where it is no longer supported by a guide.
In order that my said invention may be fully understood and readily carried into
effect will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.

rack a part of one of the plate carriers and of the chain connecting the carriers is
also shown.
Figure 17 is an end elevation of the guide course and shows two plate carriers,
one of them being tipped to deliver the plates.
Figure 18 is a side elevation of part of the guide course together with the
gearing for imparting intermittent motion to the endless series of plate carriers.
The parts are here shown in the positions they occupy at the commencement of a
movement.
Figure 19 shows some of the parts in the positions they occupy at the end of a
movement of the travelling receiving rack.
Figure 20 shows the parts represented in the preceding figure in the position of
rest.
Figure 21 is a plan showing some of the parts represented in Figures 18, 19
and 20.
Referring more especially to Figure 1. a is a shaft continuously driven by an
endless belt or otherwise, it gives motion in the manner shown to a countershaft a¹
which drives the pinion A on a sleeve which revolves freely on the shaft a. B is
the toothed rack which imparts movement to the endless chain of plate carriers.
C is the guide course for the plate carriers. a is a worm on the axis a it drives a
worm wheel a³ on the axis of one of the withdrawing rolls D; these rolls are
geared together. D₁ are other guide rolls beneath the rolls D.
The axis a also drives the axis e on which is the toothed or notched wheel E and
this serves to impart movement to the clip arms. The driving train from a to e
consists of the worm a² and wheel a³, a wheel a' on the same axis with the latter
driving a wheel aº. The wheel a is fast with the wheel as which drives a' and a*,
the latter fast upon the axis e.
In Figures 2 and the axis e and the wheel E are again seen. F is a clip arm
complete with all the working parts.

page_text: The pot Z here shown is a wide one, and requires to be provided with two sets
of clip arms working side by side. F¹ is one of the clip arms of the second series,
it is shown stript of its working parts. Provision is made for three clip arms in
each series or six arms in all; they all work similarly and in the following
description attention is directed for the most part to one only of the arms. are
the clips on the clip arms, their elasticity causes them to nip and hold the plate
when they are permitted to do so.
Conical studs f¹ form the nipping parts on one side. G is the fixed guide ring
it has notches in it at g', g² and 3. Opposite to the notches are levers H with
filling pieces H at their ends fitting the notches in the guide ring and when in
place making the circular course complete. The levers H are mounted upon a
flange on the ring G. I is the latch jointed to the clip arm, the ring G holds it in
gear with the wheel E but it drops out when it comes to an unoccupied notch in
the ring. is a pin on the clip arm which when the arm is in the position shown
serves to hold the next filling piece out of the notch g³.
The pins operate upon levers which are linked to the levers H. When the
levers H are free, the weights 1 suspended from them insert the filling pieces into
the notches.
KK are fingers jointed to the flange of the ring G; a light spring holds the
finger K² in the position shown. These fingers open the clips operating in con-
junction with the gear shown by Figures 6 and 7. Lis the trigger lever, it operates
in conjunction with apparatus more clearly shown in Figures 8 and 9 to start the
clip arm when a plate rises from the rolls D.
M are guiding prongs which serve both to guide the plate into the clip and to
support it as it is being carried to the receiving rack.
N are other guiding prongs which aid in leading the plate into the clip and then
pass rapidly away to allow the plate to pass. 3 is another pin on the clip arm
which in passing acts upon a lever n and so gives motion to the guiding prongs N.
The guiding prongs are all fixed on one axis and the lever n is connected with an
arm on the axis by a link. The pin f³ serves also another purpose; it comes
against the arm X and by moving it puts the parts of the receiving rack into
movement as hereinafter explained. C is the guide course for the sections of the
receiving rack. PP are plate holders to receive the plates from the clip arms
between their projecting pins or prongs. Each plate holder receives in succession
two plates, first a plate between the inner prongs when it is in the position
marked Pin Figure 2 and then a plate between the outer prongs when it is in a
position marked P2. are frames to which the plate holders P are pivoted; they
are also supported by projecting lugs P* resting beneath the upper guide rail o.
Upon the frames p there are also rollers ppl to run upon the guide rails o. In the
positions PP2 the lower guide rail deviates from its direct course and allows the
plate holders to tilt forward somewhat towards the clip arms as represented in
Figure 3 but elsewhere the lower guide rail o is immediately beneath the upper
guide rail and the plate holders stand upright. J is an endless chain which
connects the frames p. On each frame p is a pin p³ and by this it is propelled.
The pin is caught by a catch ql on an arm 7 fixed upon an axis Q. The arın q
makes a partial rotation to and fro.
In Figure 4 the clip arm is seen with its counterpoise F2, each clip arm is
provided with such a counterpoise.
Figure 5 shows especially how the three clip arms forming a set are carried
upon the axis.
In Figures 6 and 7 f is an axis mounted upon the clip arm, it carries a pin ƒ³
also it has an arm which by a link is connected to a lever f.
6
The lever f is on an axis f' carried by the spring clips f and the same axis
by means of short arms carries rollers. These rollers bear upon the jaws of
the clip and press them outwards when the pin f³ is moved outwards or from
left to right as seen in Figure 6. As the clip arm travels round from the
position in which it is shown in Figure 3, the pin enters the notch in the

page_text: end of the finger K². The finger permits the clip arm to travel on without
check, but thrusts the pin outwards and momentarily opens the jaws. The
action is repeated when the arm reaches the finger K' but in this case the arm is
stopped before the pin f³ has got clear of the finger K' and consequently the jaws
of the clip stand open until the clip arm next moves forwards.
In Figures 8 and 9 L' is the axis of the trigger lever L; it is carried by the
clip arm and is hollow, the axis f4 passing through it. The axis L' carries a
quadrant L2 and when the clip arm comes nearly up to the position shown in
Figure 3 this quadrant strikes against the arm of the uppermost weight and
lifts the weight.
When the plate coming up from the rolls Dinoves the trigger lever L the arm h²
escapes from the quadrant and the weight falls.
In Figures 10 and 11 the axis L' also appears together with another arm L³
upon it; this is connected by a link with the guide prongs M which are on an
axis M carried by the spring clips f. Figures 12 and 13 do not require further
description.
press
In Figures 15, I is the centre at which the latch is connected with the clip arm.
12 is the tooth which engages with the teeth of the wheel E, and I³ is a small
friction roller on the latch on which the filling pieces H¹ on the levers H
to put the latch into gear, and which when it is in gear runs on the guide ring G.
In Figure 16 the connection of the endless chain J with the frames p of the plate
carriers is seen a tonguej attached to the chain by one of the joint pins projects
through a hole in the frame p, and it may receive a split pin beyond; each frame
is connected with the chain in this manner. The flange of the upper guide rail o is
partly cut away, this is to allow the plate carrier to tip in the manner seen in
Figure 17, the tongue P* escaping when it comes to the gap in the supporting
flange. R is a guide rail which as the plate carrier travels on after the plates have
fallen out into a receiver raises it again to its erect position. Generally however
the plates will be removed by hand before the plate carrier tips.
In Figures 18, 19, 20, and 21 the pinion A and the toothed rack B are again
seen; so is also in the first mentioned figure the axis Q and arm and some other
of the parts previously described. Qis a drum on the axis Q and Q2 is a chain
lapped around the drum and attached to the rack B. Q³ is a spring coiled around
the axis Q, attached to it at one end and at the other to a fixture Q. B¹ B are
guides which carry the rack and permit of longitudinal movement. S is an axis
with a lever arm S₁ and friction pulley S2, when erect as in Figures 18 and 19 it
holds the rack B in gear with the pinion A but when inclined as in Figure 20 it
allows the rack to fall out of gear. S³ is another arm on the axis S. T is a
weighted lever loose upon the axis S. T' is a guide for this lever. T2 is a spring
fixed to the lever T and pressing on the under side of the arm S³. U is a catch
lever, it is provided with a spring U₁ and it serves to retain the arm S³ in a position
such that the other arm S2 on the axis S holds the rack B in gear.
B³ is a pin on
the rack B which at the end of the movement trips the catch lever U.
chain by which the rack B lifts the weighted lever T. W is a latch which supports
the lever T when raised. The latch is connected by a link W' with an arm X¹
which is upon the same axis with the arm X. A spring not shown presses the
latch W forward.
The action of the machine is as follows:-
V is a
The plate rising from the rolls D enters between the jaws of the spring clip
and as it does so it moves the trigger lever L. The movement of the trigger lever
is shared by the quadrant L² on the same axis with the lever and the arm h²
escapes from off the quadrant allowing the weight ' to fall. The lever H is thus
turned sufficiently about its pivot to thrust the filling piece H¹ upon it into the
hole g in the guide ring G previously occupied by the head of the latch I. The
latch is thus thrust inwards and the tooth 12 upon it enters between the teeth of
the constantly revolving wheel E. The clip arm F consequently moves forward
and the latch is kept in gear with the wheel by the guide ring G. Immediately

page_text: the clip arm commences to move the pin 5 escapes from the finger K' and the
spring clips are free to close and they take hold of the plate. Springs may
obviously be substituted for the weights /!.
The movement of the clip arm around the axis brings the pin f³ down upon top
5 of the finger K2. The finger is pressed outwards away from the centre and so a
movement is given to the lever such as to cause the opening of the spring clip
and the plate is released by it and left between the pins of the plate holder P. The
clip arm travels on without pause and as soon as the finger K2 has been passed the
clip again closes. Presently the head of the latch I reaches the opening ² in
the guide ring which it enters thereby disengaging the clip arm from the wheel E
and bringing it to rest. The opening 2 may however be occupied by a filling
piece H on the weighted lever H and if this be the case the clip arm will pass on
without stopping until further on at 93 it finds an unoccupied opening in the guide
ring. Each of the clip arms carries a pin 2 and when the arm stands at the
receiving position, this pin acting on the levers h and H holds up the weight /' and
the corresponding opening in the guide ring will then be vacant to receive the
latch of another arm coming round. Similarly if a clip arm is at rest with its
latch occupying the opening g³ the pin f2 upon it will hold up the next weight /
and the opening will be vacant and ready to receive the latch of the arm which
next comes round.
When the clip arm at the receiving point is set in motion by the rise of a plate
into the clip, the weight next below is set free and it immediately operates to
close the opening in the guide ring at 3 displacing the latch of the clip arm
previously detained at this opening. This clip arm then advances to the receiving
point and as it does so the quadrant L which it carries comes against the arm
on the upper weight; this latter is lifted and the arm comes to rest. Before
this takes place however the pin f' has come against the finger K', the finger in
turning pushes back the pin and the clip is opened.
The plates are guided from the rolls D into the clip by the two sets of fingers M
and N. The fingers M come forward when the trigger lever is moved by the
plate and the plate rests upon them as the clip arm carries it over the axis to the
receiving rack.
The fingers N when the clip arm is in the receiving position are held in place to
guide the plate by the pin f3 on the clip arm. When the clip arm starts from the
receiving position the fingers N are moved rapidly out of the way, but are replaced
by the next clip arm as it comes round.
The plates when released by the clip arms are left between the pins of the plate
holders P and the holders immediately travel on a distance. This is brought about
by the movement to and fro of the lever arm X.
Immediately after the clip arm releases the plate the pin upon the arm strikes
the arm X on the same axis with which there is the other arm X' connected with
the catch W. At this moment the catch is supporting the weighted lever T and
this lever is resting on the arm S3 which is on the same axis with the arm S¹. This
latter arm supports the rack B. The fall of the weight thus brought about raises
the rack B into gear with the constantly revolving pinion A and the rack passes
from the position of Figure 20 to that of Figure 18. The rack then commences
to move from right to left and by the mechanism already described it moves the
plate carriers forward. Also as the rack B moves towards the left it lifts the
weighted lever T until it is again caught and retained by the latch W. At
the same time the spring T2 is constrained. Finally the pin B³ comes against the
catch lever U and moves it until the lever arm S³ escapes and the spring T2 then
at once throws it and the lever arm S' into the position they occupy in Figure 20.
The rack B then drops out of gear, the guide B' is arranged as shown to admit
of this. The spring Q then brings the rack back to the starting point.
Sometimes, in order to obviate risk of breakage in place of mounting the guide
ring G on legs which prevent all movement I mount it so that it can turn around the

page_text: axis e although ordinarily it remains at rest. A convenient arrangement is to
arrange the guide ring G with an inwardly projecting flange to occupy a groove
in the wheel E. This groove surrounds the wheel and the teeth extending on
either side.
A long link is jointed to the periphery of the guide ring on the delivery side and
this extends up to one arm of an overhead lever. A rod descends from the other
arm of this lever to the frame shown in Figure 14 in which are the gear
wheels a a a. The weight of these wheels under ordinary circumstances prevents
movement of the guide ring G around the axis e but if a latch should fail to
disengage at the proper time the guide ring will yield and prevent breakage. As
the gear frame and wheels as a a' are at the same time lifted, the mechanism
necessarily comes to rest.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In an apparatus for receiving plates as they rise from a pot, the combination
consisting of an arm furnished with a clip which takes hold of the plate; a latch or
clutch which serves to connect the clip arm with a rotating axis; and a trigger
lever or instrument on which in rising the plate strikes and which then causes the
latch or clutch to engage so that the arm may carry the plate forward.
2. In an apparatus for receiving plates as they rise from a pot, the combination
consisting of a plate holder into which the plate rises whilst the said plate holder
is at rest, a rotating axis or continuously moving part, a latch or clutch serving to
connect and disconnect the foregoing parts and a trigger lever or instrument moved
by the rising plates and controlling the action of the clutch.
3. In an apparatus for receiving plates as they rise from a pot, the combination
consisting of an arm furnished with a clip, a finger which holds the clip open when
the arm is in the receiving position but permits it to close upon the plate when the
arm moves on and a finger which again opens the clip as the arm passes the place
where the plates are required to be delivered.
4. In an apparatus for receiving plates as they rise from a pot, the combination
consisting of two or more arms furnished with clips and mounted on a rotating axis;
latches or clutches which serve to connect and disconnect the arms and axis;
trigger levers or instruments which in rising the plates strike and so cause the
latches or clutches to engage; a guide which retains the latch or clutch whilst
each arm travels from the receiving point past the delivering point and then allows
it to escape that the arm may come to rest and mechanism operated by another clip
arm in its forward movement again causing the latch or clutch to engage and the
arm to advance to or towards the receiving point.
5. In an apparatus for receiving plates as they rise from a pot, the combination
consisting of an arm furnished with a clip, and mounted on a rotating axis, a latch
or clutch which serves to connect and disconnect the arm and axis, a trigger lever

to engage, and a guide which holds the latch or clutch engaged whilst the arm
carries forward and delivers the plate and then allows the latch or clutch to escape
and the arm to come to rest.
6. In an apparatus for receiving plates as they rise from a pot, the combination
consisting of a clip arm on an horizontal axis revolving intermittently and receiving
the plates as they rise, and carrying them up and over the axis, and depositing
them in an endless travelling rack which conveys the plate away moving forward
step by step as the plates are delivered.
7. In an apparatus for receiving plates as they rise from a pot the combination
consisting of a clip arm, a trigger lever or instrument actuated by the rising plate
and causing the clip arm to hold and carry the plate forward and deposit it in
