I, MARC ANTOINE FRANÇOIS MENNONS, of the Firm of Mennons and
Telescheff, Home and Foreign Patent Agents, of 8, Southampton Buildings,
in the County of Middlesex, and 27, Rue Laffitte, Paris, in the Empire of
France, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF MAGNETO-ELECTRIC BATTERIES" (a communication) to be
as follows:-
The Invention communicated to me relates to improvements introduced into
the construction of magneto-electric batteries with a view to obtaining by a
slow motion of the armatures any required quantity or intensity of electric
fluid.
The improved battery may be constructed of different circles of bar
magnets set partly around and partly above each other with corresponding

page_text: intermediate armatures mounted on wooden or other suitable discs on a
central shaft.
Figure 1 of the accompanying Drawing represents in vertical section an
apparatus comprising two circles of permanent magnets; Figure 2 represents
in cross section a series of magnets set between the four uprights of the
frame; Figure 3 is a plan of the armatures connected with the central shaft ;
Figures 4, 5, are vertical and horizontal sections of the armatures.
a, a, a, a, are the permanent magnets; b, b, are the armatures surrounded
with the metallic wire b¹, b¹; c is the central shaft, to which rotation is
imparted by the crank handle j, or other suitable mechanism; k, k, are the
uprights of the frame. When quantity of the electric fluid is required the
currents are collected by the rings d, e, Fig. 3, and from thence pass by the
conductors f, f, Fig. 1, to the commutator g, g, mounted at the upper end of
the central shaft. When intensity is desired the conductors may be connected
in one length according to circumstances. The armatures are provided with
false poles h, i, Fig. 4, the dimensions of which correspond with those of a
certain number of magnets of similar polarity, say, for instance, eight or nine
bars. The changes of polarity in the armatures at each revolution will conse-
quently be equal to the number of these armatures multiplied by the respective
series of magnets of similar polarity. The power developed being in ratio
with the number of changes of polarity produced at each revolution an
advantage may be obtained by the application of equal numbers of armatures
and magnets, as shewn in Figs. 6, 7. This arrangement is composed of three
discs, each provided with ninety-six armatures b, b, corresponding with the
same number of magnetised bars a, a, so that each revolution gives rise to
changes of polarity equal to 96 x 96=9216x3=27,648.
The armatures are constructed as shewn in Figure 8, and are coiled with
wire internally and externally-as in o, o¹, Figure 7, which represents portion
of a disc on an enlarged scale; the two intermediate circles of permanent
magnets are fixed to brass rings p, p, Fig: 6. The armature wheel or disc
is formed of hard wood or other suitable material, and is provided with two
rings m, m², composed of vertical bars overlapping each other, in which gear
the armatures b as shewn in Fig. 7. Figure 8 represents on an enlarged
scale an armature formed by the two pieces n, n³, connected with the ring m,
and separated at the centre to compel the passage of the current through the
latter. It is evident that the concentric series of magnets. and armatures; as
also the number of these elements, may be increased or decreased according
to the effect to be produced. In all cases the armature discs should be
arranged "stepways," so that when the armatures of the first series have com-

page_text: pletely passed between the magnets, as in A, Fig. 9, those of the following
series reach but half way, as in B, and those of the third series only commence
to be drawn in between the magnets, as in C. The force of attraction being
thus added to the power applied to the central shaft, the motion of the latter
is necessarily facilitated by increase in the power of the magnets.
The form, dimensions, and general details of construction of the apparatus
above described may be varied according to its intended application.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Marc Antoine François Mennons in the Great Seal Patent
Office on the 19th November 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
ANTOINE FRANÇOIS MENNONS, of the Firm of Mennons and Telescheff, Home
and Foreign Patent Agents, of No. 8, Southampton Buildings, in the County
of Middlesex, and 27, Rue Laffitte, Paris, in the Empire of France, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of May, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,.
the said Marc Antoine François Mennons, Her special licence that I, the said
Marc Antoine François Mennons, my executors, administrators, and assigns,
or such others as I, the said Marc Antoine François Mennons, 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 THE CONSTRUCTION OF MAGNETO-
ELECTRIC BATTERIES," a communication to me by Sóreu Hjorth, a person
resident at No. 10, Norrebrogade, Copenhagen, in the Kingdom of Denmark,
upon the condition (amongst others) that I, the said Marc Antoine François
Mennons, 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.

page_text: NOW KNOW YE, that I, the said Marc Antoine François Mennons, do
hereby declare the nature of the 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 accompanying Drawings,
and to the letters marked thereon, that is to say:-
The Invention communicated to me relates to improvements introduced
into the construction of magneto-electric batteries with a view to obtaining by a
slow motion of the armatures any required quantity or intensity of electric fluid.
The improved battery may be constructed of different circles of bar
magnets set partly around and partly above each other, with corresponding
intermediate armatures mounted on wooden or other suitable discs on a central
shaft.
Figure 1 of the accompanying Drawings represents in vertical section an
apparatus comprising two circles of permanent magnets; Figure 2 represents
in cross section a series of magnets set between the four uprights of the
frame; Figure 3 is a plan of the armatures connected with the central shaft ;
Figures 4, 5, are vertical and horizontal sections of the armatures.
a, a, a, a', are the permanent magnets; b, b, are the armatures surrounded
with the metallic wire b', b; c is the central shaft to which rotation is
imparted by the crank handle j or other suitable mechanism; k, k, are the
uprights of the frame. When quantity of the electric fluid is required the
currents are collected by the rings d, e, Fig. 3, and from thence pass by the
conductors f, f, Fig. 1, to the commutator g, g, mounted at the upper end of
the central shaft. When intensity is desired the conductors may be connected
in one length according to circumstances. The armatures are provided with
false poles h, i, Fig. 4, the dimensions of which correspond with those of a
certain number of magnets of similar polarity, say for instance eight or nine
bars. The changes of polarity in the armatures at each revolution will
consequently be equal to the number of these armatures multiplied by the
respective series of magnets of similar polarity; the power developed. being in
ratio with the number of changes of polarity produced at each revolution an
advantage may be obtained by the application of equal numbers of armatures
and magnets as shewn in Figs. 6, 7. This arrangement is composed of three
dises each provided with ninety-six armatures b, b, corresponding with the
same number of magnetised bars a, a, so that each revolution gives rise to
changes of polarity equal to 96x96=9216x3=27,648.
The armatures are constructed as shewn in Fig. 8, and are coiled with wire
internally and externally as in O, O', Fig. 7, which represents portion of a disc
on an enlarged scale; the two intermediate circles of permanent magnets are

page_text: fixed to bras rings p, p, Fig. 6. The armature wheel or disc is formed of
hard wood or other suitable material, and is provided with two rings m, m,
composed of vertical bars overlapping each other, in which gear the
armatures b, b, as shewn in Fig. 7. Figure 8 represents on an enlarged
scale an armature formed by the two pieces n, n', connected with the ring m, and
separated at the centre to compel the passage of the current through the
latter. It is evident that the concentric series of magnets and armatures, as
also the number of these elements may be encreased or decreased according
to the effect to be produced. In all cases the armature discs should be
arranged "stepways" so that when the 'armatures of the first series have
completely passed between the magnets as in A, Fig. 9, those of the following
series reach but half way as in B, and those of the third series only commence
to be drawn in between the magnets as in C. The force of attraction being
thus added to the power applied to the central shaft the motion of the latter
is necessarily facilitated by increase in the power of the magnets.
The form, dimensions, and general details of construction of the apparatus
above described may be varied according to its intended application.
Having now described and ascertained the nature of the said Invention and
the manner of carrying the same into effect, I declare that what I claim and
desire to protect by Letters Patent is,-
Firstly, the application in the construction of magneto-electric batteries of
a large number of small magnets set partly around and partly above each
other, and corresponding with intermediate armature discs mounted on a
central shaft, substantially as herein set forth and shewn in Figs. 1, 2, 3, 6,
of of the accompanying Drawings.
Secondly, the peculiar arrangement by which the armatures may be
applied in number equal to that of the magnets, substantially as herein set
forth and shewn in Figs. 6, 7, of the accompanying Drawings.
Thirdly, the "stepway" or zig-zag arrangement of the armature discs, in
manner and for the purpose substantially as herein set forth, and shewn in
Fig. 9 of the accompanying Drawings.
In witness whereof, I, the said Marc Antoine François Mennons,
have hereto set my hand and seal, this Fifteenth day of November,
in the year of our Lord One thousand eight hundred and sixty-seven.
