Improvements in Magneto Electric and Dynamo-electric Generators.
We, FRANK BRYAN, A.I.E.E., Electrical Engineer, 87, Wellesley Road,
Gunnersbury, W., and Major ABEL HENRY BAYLEY, of Reeth Lodge, Niton,
Isle of Wight, do hereby declare the nature of this invention to be as follows:-
This invention consists of a new form of magneto electric generator for the
production of electricity, especially applicable for providing the current for
igniting explosive mixtures used for motive power engines, but it will be under-
stood that the same arrangement may be used to produce electricity for other
purposes, if desired.
The means adopted to accomplish this end are as follows:-We may make the
wire coils or the like, in which the current is to be generated, stationary and
cause a variation in the magnetic flux through the same, by so arranging such
coils on the poles or extensions of the poles of the stationary permanent magnets
employed and causing an iron armature or armatures affixed to and carried by.
some portion of the mechanism of the engine or other device, for or by which
the current may be required or generated to approach and recede from the said
cores or coils. In the case of an explosive or other engine, we may affix such
armature or armaturos to the fly wheel, for instance, or to the end of the piston
or connecting rod or some other moving portion of the engine, so arranging the
position of the permanent. maguets and coils or the magnetic cores of such coils,
that such armatures may approach and recede from the said cores or coils and
cause as much variation as possible in the lines of force through such coils.
We may also cause the coils to be fixed as before, but attach the magnets to
some portion of the mechanism as aforesaid, a very suitable arrangement being
to let the said magnet or magnets form a portion of or, if desired, the whole
of the fly wheel, so arranging the poles of such magnets as to cause the lines
of force to cut through the coils by reason of the motion of such magnet or
magnets. In this case the weight of the magnets is usefully employed in addi-
tion to the magnetic force of the same.
The current so produced may be utilized in any of the well known ways, and
if for ignition of an explosive charge may either he commutated into an uni-
directional current or not, as desired, or caused to work an induction coil, or
the circuit traversed by such current may be broken inside the cliamber or
cylinder containing the explosive mixture by means of a movable electrode or
the like worked by a cam or other device so as to produce the necessary spark
when required.
We may also utilize more than one coil or set of coils to be operated upon by
the same armatures or magnets, either combining the effects of the currents 60
produced in such coils or sets of coils or not, as required.
We may also use one or more magnets, which may be either permanent

page_text: magnets, or in some cases clectro magnets, arranged so as to be excited by the
current generated in the inductor or generating coils, and the said magnets where
more than one is used, may be so arranged as to act either separately or in
conjunction, and either simultaneously or otherwise on one or more of the
generating coils, and the poles of such magnets may be so arranged as to alter-
nately or in other sequence reverse the direction of the magnetic flux through
the generating coils, more especially when such magnets form part of the fly-
wheel or other rotating part of the engine or other mechanism or the like.
A
The coils or their cores, or the magnets or their polar extensions may also
be made capable of adjustment as to their relative positions to each other or to
the fixed or moving magnets or armatures, so as to allow of the maximum current
being generated at any particular moment during the motion of the moving
parts of the system, whichever they may be, and such adjustment may be
arranged to be readily controlled as desired by micans of cams, levers, racks or
pinions or other mechanism, so as to cause the ignition, where the current is
utilized for this purpose, to take place sooner or later as desired. The break of
circuit inside the explosion chamber may also be controlled simultaneously,, and

by the magnets; oither combining the effects of the current so produced in such
coil or sets of coils or not, as required. We may also. use one or more magnets,
which may either be permanent magnets, or in some cases electro magnets,
arranged so as to be excited by the current generated in the inductor or generat-
ing coil; and the sail' magnets where more than one is used may be so arranged
as to act either separate or in conjunction (and either simultaneously or other-
wise) on one or more of the generating coils; and the poles of such magiiots
may be so arranged as to alternately or in other sequence reverse the direction
of the magnetic flow through the generating coils.
"The coils or their cores are made capable of circular adjustment as to their
position relatively. to the circle traversed by the moving magnets, so as to allow
of the maximum current being gonerated at any particular moment in 'the revo-
lution of the magnet or magnets and such adjustment may be arranged to be
readily controlled as desired by means of cams, levers, racks or pinions, or other
suitable mechanism, so as to cause the ignition, where the current is utilised for
this purpose, to take place sooner or later as, desired. The break of circuit
inside the explosion chamber may also be controlled simultaneously and from
the same mechanism.
Referring to the accompanying drawings:-
Fig. 1 is a view in side, elevation (partly in section) of an explosion motor
having horse shoe shaped magnet carried on the fly-wheel, so as to be revolved
thereby and therewith and,so arranged and mounted on the fly-wheel as to be
in running balance thereon; and the coils carried on an adjustable arm pivoted
to a fixed part of the motor.
Fig. 2 ts a local vertical cross sectional view (on an enlarged scale) of the fly-
wheel with magnet thereon as shown in Fig. 1; and Fig. 3 is view looking in
the direction of the arrow 4 Fig. 2 on the line 3-3.
A is motor fly-wheel.
B is magnet fixed to said fly-wheel in suchwise as to be in running balance
thereon.
CC are the poles of said magnet extending laterally from the face of said
fly-wheel-see Fig. 3.
Dis frame or stationary part of said motor.
E is shaft journalled in the part D and carrying the fly-wheel A.
FF are coils mounted on an adjustable arm Ġ which latter is rotatably
mounted on the sleeve D' of the stationary part 1), namely said arm G is fixed
to the collar which latter is so mounted on the sleeve D' as to be capable
of being moved around same.
I is lever by means of which said arm G and the coils thereon can be moved
around the shaft E and then held at any desired point.
Jis electric ignition device.
Kis induction coil.
The arm G having been adjusted and fixed' in the desired position it will thus
readily be seen that a flow of current will be caused each time the poles C of
the magnet pass the coils F and this intermittent current can thus be utilised
to ignite the charge at the desired moment in the well-known manner; or said
current may also be employed for any other desired purpose.
Instead of, or in addition to, the aforesaid circular adjustment-the coils may
be arranged and mounted in suchwise as to be capable of adjustment either (1)
radially or (2) tangentially with respect to said fly-wheel, or (3) towards or
away from said magnets so as thus to enable the strength of the current generated
to be varied as desired.
Or instead of the aforesaid circular adjustment the coils may be adjustable
tangentially only and thus variation in the timing of the explosion as well as in
the strength of the current produced can be obtained by the one adjustment.
Instead of a horse shoe shaped magnet as illustrated any other suitably shaped
magnet may be employed as desired.
