PROVISIONAL SPECIFICATION left by the said David Appleton at the Office
of the Commissioners of Patents on the 1st February 1883.
DAVID APPLETON of the City of Manchester in the County of Lancaster,
Metal Plater, "IMPROVEMENTS IN METAL PRINTING EMBOSSING AND MOULDING
PLATES, DIES OR MOULDS AND IN APPARATUS FOR USE IN THE ELECTRO PLATING
OF SUCH APPLIANCES
"
My Invention relates to the appliances used in the moulding and ornamentation
of porcelain pottery and earthenware and of tiles. The engraved copper plates
used for the above indicated purposes are found to deteriorate rapidly owing to
the softness of the metal and to the chemical re-action which takes place between
the metal and some of the colors used which re-action also affects the tint which it
is the object to obtain. The metal moulds used in the pressing or embossing of
tiles and other articles are also subject to rapid deterioration. To remedy these
defects I cover the surfaces of the said appliances with an electro coating of nickel
or of nickel combined with other metal. I prefer during the deposition of the
nickel to keep the plate or appliance in motion. In an apparatus I have devised
for the purpose a forked saddle piece resting on the cathode rod carries a shaft
which is driven by a cord or band and is provided with a fast and a loose grooved
pulley. The ends of the fork carry short shafts on which are pullies which are
connected by a cord or hand with the two pullies on the upper shaft. On the outer

which are provided with a number of sliding spring clips. When a plate is placed
in position the outer ends of these clips are drawn against the edges of the plate
whereby it is held in position. As the shafts rotate the plates are turned round
and are also moved up and down in the solution. I prefer also to give a shaking.
motion to the plates at intervals as for example a pin on the upper shaft may
strike a spring finger on the cathode rod at each revolution. By these means the
electro plating is rapidly and well done and a plate which cannot be entirely
submerged can be plated. The apparatus may be used in depositing other metals
than nickel upon the said appliances.

Metal Plater "IMPROVEMENTS IN METAL PRINTING, EMBOSSING AND MOULDING
PLATES, DIES OR MOULDS AND IN APPARATUS FOR USE IN THE ELECTRO-PLATING
OF SUCH APPLIANCES

My Invention relates to the appliances used in the moulding and ornamentation
of porcelain pottery and earthenware and of tiles. The engraved copper plates
used for the above indicated purposes are found to deteriorate rapidly owing to the
softness of the metal and to the chemical re-action which takes place between the
metal and some of the colors used which re-action also affects the tint which it is
the object of the manufacturer to obtain. The metal moulds used in the pressing
or embossing of tiles and other articles are also subject to rapid deterioration. To
remedy these defects I cover the surfaces of the said appliances with an electro-
coating of nickel or of nickel combined with other metal. I prefer during the
deposition of the nickel to keep the plate or appliance in motion, and I liave
devised an arrangement of apparatus for accomplishing this object which apparatus
I will now proceed to describe reference being made to a sheet of drawings which
I have attached hereto. In the said drawings Figs 1 and 2 represent vertical
sections taken at right-angles to each other of a plating bath fitted with my
improved apparatus the said Figs being drawn to a scale of about three inches to
the foot. In the said Figs a is an ordinary cistern to contain the plating solution
and is made of a size suitable to the requirements. On two sides of this cistern is
fixed the "cathode rod" b and upon this rod is mounted a forked saddle piece c.
At the lower end of each limb of the fork is formed a bearing for a short shaft d
on the outer end of which is fixed a disc e from which project four arms f, ƒ‚.
Upon each of the said arms a clip or holding finger g is fitted to slide and is
secured in any required position by means of a screw. The appliance say for
example a plate is held by means of the said clips which are pushed tight up
against the plate-which is indicated in dotted lines in Fig 1-and are secured in
position by means of the screws. The slight spring of the clips and of the arms f
causes the plate to be firmly held. On the other or inner end of each shaft d is
fixed a band pulley h and an endless band indicated by dotted lines is mounted on
the two pulleys and passes over two pulleys i, i which are fixed upon a short shaft
which revolves in a bearing in the upper part of the saddle c. Upon the same
shaft is fixed a third pulley k which receives a revolving motion from any suitable
source whereby the two shafts d and as a consequence the plates held by the
arins f,fare caused to revolve slowly. By this means the two plates are caused to
rotate in the solution. In some cases I form or fix short cranks upon the outer
ends of the shafts & and fix or mount the discs e upon the crank pin or on the
cranks so that the said discs revolve around the axes of the said shafts whereby the
plates are caused to rise and fall as well as to revolve in the solution but a similar
effect may be obtained by securing the plates in positions which are excentric with
respect to the axes of the shafts d. In some cases I impart a shaking motion to
the plates in addition to the revolving motion. This may be effected by arranging
for a pin upon the upper shaft to strike a spring finger on the cathode rod at each
revolution or the outer end of one of the arms f may strike a finger or projection
or other suitable means may be adopted. The anodes are represented by the
plates,. The necessary battery connections are made in the usual or in a

page_text: suitable manner but it has not been considered necessary to show them in the
drawings. I do not confine myself to the precise details of the apparatus nor to
the method of driving the parts carrying the plates. I prefer that the plates shall
be entirely immersed as in the example but in some cases the apparatus may be
used in the coating of a plate too large to be submerged. The apparatus
may be used in depositing other metal than nickel upon the said plates or
appliances.
Having now fully set forth and indicated the nature of my said Invention and
the manner in which and the means whereby I carry the same into practical effect
I would have it to be understood that I claim :-
First. Coating the working surfaces of plates or appliances of the nature herein
mentioned with an electro-deposit of nickel for the purpose set forth.
Secondly. The apparatus substantially as set forth and indicated hereinbefore
and in and by the accompanying drawings.
And lastly. The employment of apparatus for revolving and shaking the within
named plates, moulds or appliances in the plating solution during the coating of
such plates, moulds or appliances with an electro deposit of nickel or other suitable
protective metal.
In witness whereof I the said David Appleton have hereunto set my hand and
seal this seventeenth day of July in the year of our Lord one thousand eight
hundred and eighty three
