page_text: LETTERS PATENT to Joseph Rushton Turnock of the Yspitty Iron and Tin
Plate Works situate in the parish of Dafen in the County of Curmarthen
Tin plate Manufacturer, for an invention of IMPROVEMENTS IN APPARATUS
FOR PICKLING AND SWILLING METAL PLATES
PROVISIONAL SPECIFICATION left by the said Joseph Rushton Turnock at
the Office of the Commissioners of Patents on the 15th April 1882.
JOSEPH RUSHTON TURNOCK of Yspitty Iron and Tin plate Works situate in the
Parish of Dafen in the County of Carmarthen Tin plate Manufacturer "IMPROVE-
MENTS IN APPARATUS FOR PICKLING AND SWILLING METAL PLATES
"}
This Invention has for its object improvements in apparatus for pickling and
swilling metal plates.
For this purpose I employ a moveable pot or pots to contain the pickle and the
water for swilling. The pots are suspended or otherwise carried so that they are
capable of receiving a reciprocating motion and such a motion is imparted to them
by connection with a crank or in some other convenient manner. The plates to be
pickled or swilled aro carried in racks which are separate from the pot and are
lowered into it. The movement of the pot causes the liquid to flow to and fro
amongst the plates in a manner very favorable to efficient and rapid action.
I provide the racks with wheels to run upon an overhead railway to conduct
them to and from the pot and the places for loading and unloading. The rails
immediately over the pot are moveable and form part of a frame which is supported
by a counterpoise. When the rack comes upon the moveable rails they are lowered
and the rack with the plates descends into the liquid contained in the pot. The
lifting and lowering of the counterpoise and rack I effect by means of a steam or
hydraulic cylinder. The cages are supplied with upper rails to enable the empty
carriage to return to be loaded with fresh plates.

IMPROVEMENTS IN APPARATUS FOR PICKLING AND SWILLING METAL PLATES
This Invention has for its object improvements in apparatus for pickling and
swilling motal plates.
For this purpose I employ a moveable pot or pots to contain the pickle and the
water for swilling. The pots are suspended or otherwise carried so that they are
capable of receiving a reciprocating motion and such a motion is imparted to them
by connection with a crank or in some other convenient manner. The plates to
be pickled or swilled are carried in racks which are separate from the pot and are
lowered into it. The movement of the pot causes the liquid to flow to and fro
amongst the plates in a manner very favourable to efficient and rapid action.
I provide the racks with wheels to run upon an overhead railway to conduct
theni to and from the pot and the places for loading and unloading. The rails
immediately over the pot are moveable and form part of a frame which is supported
by a counterpoise. When the rack comes upon the moveable rails they are
lowered and the rack, with the plates, descends into the liquid contained in the
pot. The lifting and lowering of the counterpoise and rack I effect by means of n
steam or hydraulic cylinder The cages are supplied with upper rails to enable the
empty carriage to return to be loaded with fresh plates.
The Drawings hereunto annexed show apparatus constructed ns above
described.
Figure 1 is a side view of the apparatus and Figure 2 is a vertical cross section
on the line A, B, in Figure 1. Figure 3 is a perspective view of one of the lifting
and lowering cages.
a, a, are overhead beams carried by supports b. b. c. c. are rods suspended from
pins d. d. carried by cross pieces fixed to the boains a. The lower extremities of
these rods carry the pots of the pot c. is the pickling pot and the pot f. the
swilling pot. Two of the rods c, are connected by links to crank pins g. on a
shaft driven in any suitable manner-in this way the pots c. f. have a
reciprocating to and fro motion given to them.
If desired the links might be made shorter so that the pots might in addition to
receiving a practically to and fro horizontal motion receive in addition a more or
less up and down motion or other moans might be adopted for giving a to and
fro reciprocating motion to the pots.
i. are lifting and lowering cages suspended over the pots e. f. by chains j. j,
which pass over pullies k. k. the other extremities of the chains j. j. are fixed to the
upper ends of the piston rods of steain or hydraulic cylinders . . and the lower
ends of the piston rods have counterpoise weights m. m. attached to them to
somewhat overbalance the weight of the cages i, i. nnd loaded rack carriages
which they have to carry. The cages are provided with upper and lower rails
n. n'. either of which can be brought into a line with the rails upon which tho
rack carriages rest when loading and unloading o, o, are the rack carriages they
are provided with wheels 2. 2. which run upon the rails, three such rack carriages
are employed. The cages are at all times retained from swinging to and fro by
guides one of which is shown at Figuro 2, q are the rails of the loading stago
and q' the rails of the unloading stage.

page_text: The mode of working is as follows:-The rack o on the loading stage 9
filled
with plates (about half a box of "Black" or a box of "White" in each division
and as the racks or carriages o. o, are loaded from both sides those shewn would
take 8 boxes of "Black" or 16 of "white") when loaded the rack or carriage o.
is pushed along the rails q on to the lower rails n', of the pickling cage i, steam
or water under pressure is then admitted to the cylinder l, which forces its piston
upwards and allows the loaded cage to descend into the pickling pot c.
The liquid
in this pot then flows to and fro between the plates as tho pot is moved to and fro
whilst the cage which carries the plates remains at rest.
When pickled the steam or water in the cylinder is allowed to escape and the
counterpoise weight being somewhat heavier than the loaded cage i descends and
the cage is raised out of the pickling pot e.-The carriage is then pushed over to
the water cage i. and lowered into the swilling pot fa fresh crrriage is then put
into the pickle and by the time the plates are pickled the first lot is swilled raised
and pulled on to the unloading stage q' the second lot then goes into the swilling
and the third cage into the pickle and while these are down the first carriage comes
back over the upper rails n of the cages and is loaded ready for the pickle and so
on without intermission.
In place of the cylinders 7, . being arranged vertically as shown they might be
arranged horizontally between the pulleys k. k. and k. . The piston rods would
in this case project through the cylinder covers at each end of the cylinders. Tho
balance weights would be attached to the portion of the chain deponding from the
outer pulleys k.
Having thus described the nature of my said Invention and the manner of
performing the samo I would have it understood that I clain :-
First. The combination of apparatus for pickling and swilling metal plates
substantially as described.
Second. The combination of pickling and swilling pots which have an oscillating
to and fro movement given to them with racks for carrying plates which can be
lowered into the pots and held stationary therein whilst tho pots are oscillated to
and fro.
In witness whereof I the said Joseph Rushton Turnock have hereunto.set
my hand and seal this twelfth day of October in the year of our Lord One
thousand eight hundred and eighty two.
