COMPLETE SPECIFICATION.
A Galvanic Chain for Curative Purposes.
I, Mrs. FRIEDERIKE FRITSCHE, of 67 Leipzigerstrasse, Berlin, in the German
Empire, Gentlewoman, do hereby declare the nature of this invention and in what
manner the saine is to be performed, to be particularly described and ascertained.
in and by the following statement :—
This invention relates to a device, the object of which is to convey a slight but
uniform electrical current to the human body, as a remedy for rheumatic pain,.
gout, convulsions and like disorders, but more especially as a convenient means for
giving relief to children during the teething period, by soothing the pain caused
by the cramps or spasms attending dentition, and in some cases bringing about a
complete cessation of such pain; the said device mainly consisting of a chain
intended to be placed round the neck of the invalid, and the effect of which is.
similar to that of a voltaic cell made up of elements of copper and zinc.
The component parts which are necessary in a cell of this class to generate an
electrical current, viz.-copper, serving as a positive electrode; zinc, acting as a
negative electrode; and acid, employed as an exciting liquid, are combined in the
manner illustrated in the accompanying drawings.
A small copper chain a, made of wire about one millimetre in diameter, and
consisting of rounded links, is connected by a cord c, of wool or similar material,.
with another chain b, similar to the first in size and shape, but made of zinc ; the
zinc chain being in its turn joined to another copper chain. Thus a uniform
connection is obtained between zinc, wool, copper, and so on, in rotation. The
wool cord, when in use, absorbs the perspiration secreted by the body, the wool
here accomplishing the purpose of the third or intermediate component of the cell,.
viz. the exciting agent, generally consisting of diluted acid.
When the chain is placed in contact with the body, preferably round the neck,.
it is only necessary to connect the cords c' and c², terminating it at either end, to.
close or form an electrical circuit, and the feeble current thus generated is caused.
to produce its beneficial action upon the nervous system of the patient.
An essential advantage of the chain over similar arrangements hitherto devised
is that it is capable of exactly fitting or accommodating any part of the body
which may happen to be the seat of the pain or disorder, while at the same time.
it is not apt to inconvenience the patient by its weight, or by chafing the skin.
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--
A chain adapted to act as a voltaic cell, mainly consisting of zinc and copper
chains with rounded links, connected to each other alternately, or in rotation, by
cords made of material capable of readily absorbing perspiration, for the purpose
of generating a slight but uniform electrical current calculated to produce a
curative action upon the human body, it being more especially intended to promote
dentition in the case of infants, and to procure relief or cessation of pain where
dentition is accompanied by spasms or convulsions, substantially as described and
illustrated in the drawings.
