page_text: LETTERS PATENT to Siegmund Moore, of Liverpool Street, Bishops-
gate Street, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN THE MEANS OF AND APPARATUS FOR ELECTRO-PLATING,
SAID APPARATUS BEING ALSO APPLICABLE TO MEDICAL PURPOSES
Sealed the 19th February 1864, and dated the 22nd August 1863.
PROVISIONAL SPECIFICATION left by the said Siegmund Moore at the
Office of the Commissioners of Patents, with his Petition, on the 22nd
August 1863.
I, SIEGMUND MOORE, of Liverpool Street, Bishopsgate Street, in the
County of Middlesex, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MEANS OF AND APPARATUS FOR ELECTRO-PLATING,
SAID APPARATUS BEING ALSO APPLICABLE TO MEDICAL PURPOSES," to be as
follows:-
This Invention. consists in certain improvements in the method of and
apparatus for electro-plating, said arrangement of apparatus being also appli-
cable to medical purposes.
According to the ordinary method of depositing metals by the aid of electricity
the positive and negative currents are conveyed from the battery plates direct
to the bath by means of wires.
Now my Invention consists in interposing between the battery and the
bath containing the object to be coated and the metallic solution an electro-
magnetic apparatus or instrument which will give out both the direct,
and the to and fro, or intermittent galvanic currents as may be desired. The

page_text: apparatus is somewhat similar to the ordinary electro-magnetic apparatus
wherein the coil of insulated wires surrounds a core, and forms a hollow helix,
the wires from the battery are to be connected by binding screws, to the primary
wires of the coil, and the positive and negative poles of the direct current are
to be connected to the bath, the negative pole being connected to the article
to be plated, and the positive pole to the gold or silver plate in the bath.
I propose to improve the apparatus by the application of a new construction
of regulator whereby I can command the power created by the electric current.
Instead of allowing the current to pass out of the machine by nietallic con-
ductors only, I convey one of the wires from the lower part of the apparatus
upwards into a glass tube containing a small quantity of water or liquid; the
tube is set in a brass socket, to which the wire is attached, the water resting
on the surface of the socket conducts the electricity to a plunger or rod of
metal inserted from the top of the tube through a metallic cap, from which
cap a final wire conducts the electric current from the apparatus. It is
thus evident that according to the depth to which the metallic rod is placed
in the water or liquid, a greater or less degree of contact will be created
between said rod, and the electricity conveyed to the liquid from the machine,
and thus the electric power can be controlled at pleasure.
By these improvements the process of electro-coating with metals can be
carried on with greater rapidity and perfection than by the ordinary methods,
and for medical purposes the apparatus will be found to possess advantages over
the ordinary medical galvanic machines superior to any previous apparatus in
consequence of the direct current combined with the to-and-fro movements
which no instrument for medical purposes hitherto possesses.

that I, the said Siegmund Moore, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature. of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters'
Patent.
.
•
NOW KNOW YE, that I, the said Siegmund Moore, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My Invention consists in certain improvements in the method of and
apparatus for electro-plating or gilding, said arrangement of apparatus being
also applicable to medical purposes.
.
According to the ordinary method of depositing metals by the aid of elec-
tricity the positive and negative currents are conveyed from the battery plates
direct to the bath by means of wires.
Now, by my Invention, I interpose between the battery and the bath con-
taining the object to be coated and the metallic solution an electro-magnetic
apparatus or instrument which will give out both the direct, and the to and fro,
or intermittent currents as may be desired. The apparatus is somewhat
similar to the ordinary electro-magnetic apparatus wherein the coil of insulated
wires surrounds a core and forms a hollow helix, but I proceed to describe the
same by aid of the Drawings hereto annexed, and the figures and letters of
reference marked thereon, as follows:-
DESCRIPTION OF A DRAWINGS.

page_text: a is the base of the instrument; and 6 the coil; c, c², are the primary wire
binding screws; d, d', are the secondary wire binding screws; e is the regu-
lator, (hereafter described), through which the secondary wire is connected;
f and 9 denote the situations above which are the binding screws of the
battery wires, and I proceed to describe the course of the direct or primary
current, and the to and fro or intermittent current respectively.
Firstly, with regard to the primary current.-The electricity from the
platinum end of the battery enters the apparatus at the binding screw over f..
and is conducted down to the wire soldered thereto. This wire passes
upwards, and is connected to the projection i holding the armature and
spring. The wire also continues by eight coils, more or less, along the squib,
and comes out as shewn at h' to battery bind screw g. The screw ¹, in contact
with the platinum on the spring, is connected by the wire to the primary
bind screw C. The other primary bind screw c¹ being connected to the
battery bind screw g, by the wire m.
Secondly, with respect to the secondary current. The wire h before its
exit at h' is connected at about six inches distance within to the secondary
wire by soldering them together in continuation. The secondary wire proceeds
about sixteen hundred feet along the coil, and comes out as shewn by the
wire n, which is then connected at n' to a wire passing upwards behind the
regulator e to the top or cap o thereof, the plunger or rod p conducts the
current down to the water or liquid in the glass tube 9, whence it proceeds by
the wire to the secondary bind screw d. The other secondary bind screw d¹,
is connected. with battery bind screw g, by the wire m, as in the first case.
It is not necessary to use both the bind screws c, d, as one would answer the
purpose, but the apparatus looks more complete or uniform with both
attached thereto. It will be obvious that by raising the plunger p, from the
conducting liquid in the regulator, power will be taken away from the
secondary and conveyed to the primary wire, and vice versa. The primary
-electric current is applied to the purpose of electro-deposition by means of
conducting wires from the binding screws c, c¹, the wire from c being con-
nected to the metal to be decomposed in solution in the bath, and the wire
from c to the article to be coated. Of course, however, this arrangement
would have to be reversed if the battery bind screw f were connected to the
zinc element instead of the platinum or negative plate of the battery. The
to and fro or intermittent current is applied to medical purposes by wires from
the secondary bind screws d, d', and by metal handles or wet sponges or other
means to the body of the patient. The metallic solution should not be the
ordinary cyanide solution, as used as present, but I reserve to myself the use

page_text: of specially prepared solutions applicable to my Invention. By the inter-
vention of this apparatus a fine deposit of silver or gold is obtained on the
surface of spoons, forks, tea, and dinner services, epergnes, candelabra, and
other objects, and this with a rapidity not hitherto accomplished, the character
of the deposit being superior to that acquired by the ordinary slow deposit, and
as smooth as glass.
Having now described the nature of my said Invention, and the means by
which the same is to be performed, I would remark in conclusion that I do
not limit myself to the precise details and configuration of parts herein
described and shewn, as the same may be modified or varied without departing
from, the principles on which my Invention is based, but what I claim and
desire to be secured to me by the herein in part recited Letters Patent are,.
the "Improvements in the Means of and Apparatus for Electro-plating, said
Apparatus being also applicable to Medical Purposes," substantially in the
manner herein specified and illustrated.
In witness whereof, I, the said Siegmund Moore, have hereunto set
my hand and scal, this Twentieth day of February, One thousand
eight hundred and sixty-four.
