IMPROVEMENTS IN ARRANGING D
Year: 1858

page_text: LETTERS PATENT to Geminiano Zanni, of Union Street, Barnet, in the
County of Middlesex, for the Invention of "IMPROVEMENTS IN ARRANGING
D"
Sealed the 29th April 1859, and dated the 29th October 1858.
PROVISIONAL SPECIFICATION left by the said Geminiano Zanni at the
Office of the Commissioners of "Patents, with his Petition, on the
29th October 1858.
I, GEMINIANO ZANNI, of Union Street, Barnet, in the County of Middle-
sex, do hereby declare the nature of the Invention for "IMPROVEMENTS IN
ARRANGING MAGNETO-ELECTRIC MACHINES FOR MEDICAL AND OTHER PURPOSES," to
be as follows:-
This Invention has for its object improvements in arranging magneto-
electric machines for medical and other purposes. Heretofore the magneto-
electric machines employed for medical purposes have had motion given
to them by hand when required for use, and in some cases magneto-
electric machines of large size, and employed for other purposes have been
driven by steam power. Now this Invention consists in combining magneto-
electric machines with maintaining springs and wheelwork, so that when they
are required for use, the spring being liberated causes the armature of the

page_text: machine to rotate, and so produces a succession of currents or shocks in the
circuit of which the wire coils surrounding the armature form a part. It is
evident that a weight may be employed in place of a spring for actuating the
armature and coils, and in some cases the use of a weight is as advantageous
as the use of a spring.
Magneto-electric machines combined in this manner may be employed
conveniently for medical purposes, for working electric telegraphs, and for
other uses.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Geminiano Zanni in the Great Seal Patent Office on the
29th April 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEMINIANO
ZANNI, of Union Street, Barnet, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of October, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Geminiano Zanni, Her special license that I, the said Geminiano
Zanni, my executors, administrators, and assigns, or such others as I, the said
Geminiano Zanni, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
ARRANGING MAGNETO-ELECTRIC MACHINES FOR MEDICAL AND OTHER PURPOSES,'
upon the condition (amongst others) that I, the said Geminiano Zanni,
by an instrument in writing under my hand and seal, 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 Geminiano Zanni, 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, reference being had to the Drawings hereunto annexed, and to the
letters and figures marked thereon (that is to say) :-

page_text: This Invention has for its object improvements in arranging magneto-
electric machines for medical and other purposes. Heretofore the magneto-
electric machines employed for medical purposes have had motion given
to them by hand when required for use, and in some cases magneto-electric

the armature and coils, and in some cases the use of a weight is as advan-
tageous as the use of a spring. Magneto-electric machines combined in this
manner may be employed conveniently for medical purposes, for working
electric telegraphs, and for other uses.
From the previous description, any one acquainted with apparatus for
obtaining electric currents will readily understand the nature of my Invention,
and so that it may be fully understood, I now describe the Drawings hereunto
annexed, which shew several views of a magneto-electric machinė suitable for
medical or other purposes, arranged with improvements according to my
Invention, thus giving a practical illustration of the mode of putting it into
operation.
I
Fig. 1 shews a plan of the case containing the machine with the cover
removed; Fig. 2 shews a plan partly in section; and Fig. 3 shews a longi-
tudinal section through the line 1, 1, of Fig. 2. a. is an ordinary permanent
horse-shoe magnet fixed to the bottom of the box or case b, b, and c is a keeper
or armature of soft iron placed across the ends or poles of the magnet, and it is
arranged so as to be capable of being moved and retained at different distances
from the magnet in order to regulate the strength and rapidity of the currents
or shocks produced by the rotation of the armature and coils of insulated
wire d, d, supported over and near to the two ends or poles of the magnet a.
The armature and coils of insulated wire d, d, are caused to rotate as follows:-
e is a spring barrel containing a powerful helical spring, which gives motion
to the axis of the fuseef by means of the cord or chain e¹, as is well under-
stood; the toothed wheel fi on the axis f, takes into and drives the pinion g¹
on the axis g, on which is fixed the toothed wheel g, which takes into and
drives the pinion h¹ on the axis h, on the upper end of which is fixed the
toothed wheel h², which gears with the pinion i fixed on the axis of the
rotating armature d, and gives motion thereto, and the pinion i and the axis 2¹

page_text: are insulated from the wheel h³, and the top plate through which it passes
by means of ivory inserted for that purpose. The currents of electricity
induced by the rotation of the armature and coils of wire d, are conducted
away from the two poles of the magnet by the metallic connections ; and j¹,
and contact is made and broken to produce a succession of currents or shocks
by the metal spring k, which bears against the axis of the armature d, the
axis being flattened at that part as shewn in the separate view at Fig. 4,
which acts as a break to the metallic contact during the rotation of the arma-
ture, and is a screw which may be caused to press on the spring k, and thus
retard or stop the rotation of the armature d; m, m³, are metallic connections
with the parts j, j, to which the metal tubes or handles n, n¹, are attached
when the apparatus is used for medical purposes.
When this apparatus is employed for the transmission of electric currents
for telegraphic purposes, then the poles of the magnet are connected through
the parts j, j, with the telegraphic wires, in combination with suitable
indicating apparatus as is well understood.
It will be evident from the foregoing description that the arrangement of
the apparatus may be greatly varied without departing from the character of
my Invention, and in place of giving motion to the armature d by means of a
maintaining spring, a weight may be employed to give motion thereto as is
well understood. And for telegraphic and other purposes, I prefer to employ
a weight to give motion to the apparatus in place of a spring.
In witness whereof, I, the said Geminiano Zanni, have hereunto set my
hand and seal, the Twenty-ninth day of April, in the year of our
Lord One thousand eight hundred and fifty-nine.
