Works Loughor R.S.O. South Wales do hereby declare the nature of my inven-
tion for IMPROVEMENTS IN APPARATUS FOR ANNEALING, PICKLING, COATING AND
CLEANING METAL PLATES OR SHEETS to be as follows:-
For lowering and raising metal plates or sheets I use a cage working in a frame.
The frame in its simplest form is made as follows. A suitable foundation plate
(square or oblong) in the corners of which are fixed pillars or guides rising to a
similar plate on top of the pillars. In the lower plate are rivetted rows of pins or
division plates rising to a height of about half the height of the frame. In the
upper plate are fixed similar rows of pins the points of which hang downward and
alightly overlap the points of the lower rows and being suitably bent, as the cage.
rises and falls the plates therein are worked from one row to another and in due
course come out at the opposite side of the machine to which they were put in. In
another form of machine I hang the upper row of pins and by suitable means they
are oscillated and in this way they work the sheets from one row to the other as
the cage rises and fall.
Working between the guides I have a cage into which the plates are put either
singly or several at a time, this cage is lowered and raised by a beam worked by a
cam or other suitable mechanism. As the plate in the cage is lowered it enters the
first row of the bottom pins, the top row then being oscillated over towards the
entrance side of the frame the plate rises between the first rows of top pins, as soon
as the plate has risen sufficiently high to pass over the points of the bottom rows,
the upper rows are drawn over until the plate therein is immediately above the
second row of bottom pins into which it is then lowered, the upper pins then go
back and the plate rises into the second upper row and on again being drawn
forward it comes over the third row of bottom pins into which it is lowered, this
process is repeated as often as is found necessary until the plates at length come out
at the opposite side of the machine.
In the process of annealing plates, the machine may be placed in a suitably
heated chamber and the plates fed into and taken from it by means of rollers or
other suitable mechanism.

page_text: In pickling and swilling suitable fingers or self-acting tongs may be used in
transferring the plates from the pickle to the swilling pot.
In coating plates, the first machine would be placed in a grease or other flux
pot and the greased plates transferred to the machine in the molten metal pot by
means of rollers or movable fingers the plates are then by the machine worked
through the molten metal and come out the other side either simply tinned or
directly through the finishing rollers. In this pot I employ a scraper or plough so
arranged that on the cage rising the plough removes the scruff or other impurities
from the surface of the metal and allows the plate to come out free from scruff, the
said scraper or plough may be fixed in any suitable way and may be employed.in
any pot whether the plates are manipulated by means of the cage or otherwise.
Above or below the scraper may or may not be fixed brushes made of hemp or other
suitable material for the purpose of removing any surplus metal.

I JOSEPH RUSHTON TURNOCK Iron Steel and Tinplate Manufacturer Yspitty
Works Loughor R.S.O. South Wales 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:-
For lowering and raising metal plates or sheets I use a cage working in a frame.
The frame in its simplest form is made as follows. A suitable foundation plate
(square or oblong) in the corners of which are fixed pillars or guides rising to a
similar plate on top of the pillars. In the lower plate are rivetted rows of pins or
division plates rising to a height of about half the height of the frame. In the
upper plate are fixed similar rows of pins the points of which hang downwards and
slightly overlap the points of the lower rows, and being suitably bent, as the cage
rises and falls the plates therein are worked from one row to another and in due.
course come out at the opposite side of the machine to which they were put in. In
another form of machine I hang the upper rows of pins and by suitable means they
are oscillated and in this way they work the sheets from one row to the other as
the cage rises and falls. Working between the guides I have a cage into which the
plates are put either singly or several at a time, this cage is lowered and raised by
a beam worked by a cam or other suitable mechanism. As the plate in the cage is
lowered it enters the first row of the bottom pins, the top row then being oscillated
over towards the entrance side of the frame the plate rises between the first rows
of top pins, as soon as the plate has risen sufficiently high to pass over the points
of the bottom rows the upper rows are drawn over until the plate therein is
immediately above the second row of bottom pins into which it is then lowered,
the upper pins then go back and the plate rises into the second upper row and on
again being drawn forward it comes over the third row of bottom pins into which
it is lowered, this process is repeated as often as is found necessary until the plates
at length come out at the opposite side of the machine.
In the process of annealing plates, the machine may be placed in a suitably heated
chamber and the plates fed into and taken from it by means of rollers or other
suitable mechanism.
In pickling and swilling, suitable fingers or self acting tongs may be used in
transferring the plates from the pickle to the swilling pot.
In coating plates, the first machine would be placed in a grease or other flux pot
and the grease plates transferred to the machine in the molten metal pot by means
of rollers or moveable fingers, the plates are then by the machine worked through
the molten metal and come out on the other side either simply tinned or directly
through the finishing rollers. In this pot I employ a scraper or plough so arranged
that on the cage rising the plough removes the scruff or other impurities from the
surface of the metal and allows the plate to come out free from scruff, the said
scraper or plough may be fixed in any suitable way and may be employed in any
pot whether the plates are manipulated by means of the cage or otherwise. Above
or below the scraper may or may not be fixed brushes made of hemp or other suitable
material for the purpose of removing any surplus metal.

page_text: In order that my said invention may be fully understood and readily carried
into effect I will proceed to describe the drawings bereunto annexed.
DESCRIPTION OF DRAWINGS.
Figure 1 is a side elevation of the apparatus; it is here shown without any pot
or containing vessel. a and b are top and bottom plates, c.cc are pillars or guides,
ddd the cage (shown at half stroke), ee the rod by which cage is raised and
lowered, ff the beam, g safety bearing, h any convenient support, i eccentric or
cam, k counter weight, ƖƖ bars across the top of the cage called "pushers," m m
bars across the bottom of the cage called "lifters," nn top rows of oscillating pins
or division plates, o o bottom rows, P the rod for oscillating top row of pins or the
pins may be made to oscillate by having projections actuated by the rising and
falling of the cage. The shaded area p p p indicates a plate or sheet being pushed
down between the first rows of bottom pins.
Figure 2 is an end view showing the plates p p p passing through the machine;
p has just begun its first journey downwards and p its last journey downwards
the dotted lines show position of the top pins and plates at half stroke on the next
upward journey of the cage. p³ is now in a position to be removed from the
machine and when the cage has reached the top of its stroke the top pins are
drawn again into a vertical position and a fresh plate can be put into the cage so
that there are always the requisite number of plates passing through the machine
at the same time; the other letters refer to same portions as Figure 1.
Figure 3 is a section of Figure 1 through the line q q letters refer to same parts.
Figure 4 is a plan of cage which is a simple framework of iron or suitable
metal fitting loosely round the guides letters refer to same parts as Figures 1
and 2. In some machines I put the pushers and lifters diagonally as shown by
dotted lines in which case the pins shown in Figures 7 and 8 are so arranged
that the whole of the plate in passing through the machine gets its surface rubbed
by the points of the pins for the purpose of removing impurities from its surface.
Figure 5 is a plan of a modification of the cage and guides for very light work,
only two guides c c being used. The cage d d d is made just to clip them and
pushers and corresponding lifters project from the cage fastened in any convenient
way the dotted lines show the diagonal "lifters" and "pushers" sometimes used.
Figure 6 is a front view of modification of cage letters refer to same parts as
Figures 1 and 2 specially suited for manipulating one sheet at a time and for light
work and cage is raised and lowered by a rod hinged at or near the middle of the
upper bar.
Figure 7 is a section showing a modification of the pins, no alteration being
necessary in frame guides or cage, bottom pins rrr are fastened to bottom plates
and top pins 888 to top plates. The pins or division plates overlap and are bent
as shown. The plates p p p are "shunted" from one row to the other by the
simple action of the rising and falling of the cage. and m show sections of
"pushers" and "lifters" of the cage. The drawing shows the cage at half stroke
downwards the dotted lines show the plates as they would be when the cage, on
its upward journey, reaches the same position. The pins may either be rigidly
fastened at top and bottom and plates made to spring the points open as they pass
through or they may have a little play and be kept in their places by means of a
weight attached to the outer rows as shown, or by any other simple means. t shows
the position of a metallic scraper or brush used in the process of tinning plates it
would be fixed either below or immediately above the level of the molten metal
and may be used fixed underneath the finishing rolls of the grease pot or between
two pairs of rollers either in the tinuing machine or finishing pot. t shows the
spring at each end to keep the scrapers together. u is a finishing brush made of
hemp asbestos or other suitable material this would be fixed upon the top of the
tin pot or grease pot, the machine delivers the plate up between these brushes as
shown at dotted line p³ until the edge of plate appears above the finishing brush

page_text: when it may be caught hold of and removed in any convenient way. u¹ shows the
springs at each end to keep the brushes together.
Figure 8 is a front view of Figure 7 letters referring to the same parts. 17 and
mm are sections of the lifters and pushers of the cage, the plate ppp is shown
on its downward journey. The scraper t is made either of sheet metal or strips of
sheet metal as shown by the dotted lines.
Figure 9 is a section of a tinpot v provided with a grease chamber w and
rollers xxxx, the division y dips below the level of the molten metal shown at z
therefore the necessary depth of grease can be kept in the roll chamber, either of
the above described machines being placed in the body of the tinpot would deliver
the plates as shown at p³ through the scraper t up to the rolls which would then
withdraw the plate finished p¹ shows the plate being put into the machine.
Figure 10 is a vertical section and shows the combination of this apparatus with
the grease or flux. In this pot there may be 4 or more rollers as shown and the
machine delivers its plate up to the "nip" of the bottom pair of rolls, this pair of
rolls and if necessary the pair above are kept covered with molten tin either by
working in troughs as shown which troughs are kept full by means of a pump
raising the metal from the bottom of the pot say a few inches in depth or the
pump may be made to deliver a stream of metal on to the upper nip of the rollers.
The remainder of the pot is filled with molten grease and the plate may receive its
coating by simply passing up through the rollers, the top pair of rolls remove the
surplus metal after the plate has passed through a scraper beneath the uppermost
pair of rolls.
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. Apparatus for annealing pickling coating and cleaning metal plates or sheets
consisting of rows of pins or like instruments and a cage or carrier conveying the
plates or sheets from one set of pins or instruments to the other and mechanism
imparting movement to one set of pins or instruments; the whole so arranged that
the plates or sheets inserted at one end of the apparatus are carried on progressively
to the other end substantially as described.
2. Apparatus for annealing pickling coating and cleaning metal plates or sheets
consisting of two rows of pins or like instruments and a cage or carrier conveying
the plates or pieces from one set of pins or instruments to the other; such pins or
instruments being of such form or curvature that thereby the plates or sheets
inserted at one end of the apparatus are carried progressively on to the other end
substantially as described.
3. The combination of apparatus such as that to which the preceding claiming
clauses relate, with a tinning pot substantially as described in respect to Figure 9.
4. The combination of apparatus such as that referred to in the preceding
claiming clauses with a grease or flux substantially as described in respect to
Figure 10.
5. The application of a metallic scraper or brush substantially as described in
respect to the Figures 7, 8, 9 and 10.
6. My improved apparatus for annealing pickling coating and cleaning metal
plates or sheets substantially as described and illustrated by the annexed drawings.
