Improvements in Magneto Electric Generators and Appliances for
Use in Connection therewith.
EDWARD COX-WALKER of Feethams, Darlington, Engineer and ALAN ARCHIBALD
CAMPBELL SWINTON 75 Queen Victoria Street London, Engineer, do hereby declare
the nature of this invention to be as follows:-'
Our invention relates to improvements in Magneto Electric Generators, suitable
for actuating bells, indicators and other electric signals and in appliances for use in
connection therewith.
In accordance with our invention we employ an armature of the ordinary shuttle
form or any suitable description wound with conducting wire and arranged between
the two pole pieces of a permanent steel or other magnet of the usual horse shoe or
similar forin so that it can be rotated in the ordinary manner.
We find it convenient to fashion the pole pieces which should be of soft iron each
with a groove or slot in which the poles of the simple or compound permanent magnet
employed may be held, the pole pieces being of suitable form to admit of the
armature being placed with its axis parallel to the legs of the magnet, so that this
axis if continued would pass through the yoke of the said magnet.
The armature axis may conveniently be supported in bearings formed in end pieces
of suitable non-magnetic material fastened across the poles of the magnet from one
pole piece to the other, these end pieces, which may conveniently be fixed to the pole
pieces by means of screws, serving also to keep the pole pieces rigid and being
conveniently fitted with feet for the whole apparatus to stand on or for fixing the
same where required or on to any base of wood or other material that may be
wanted.
The armature may conveniently be protected from dust or injury by two plates of
suitable material fitted to cover the spaces between the pole pieces, these plates being
fixed across the poles of the magnets on either side of the armature. The armature is
by this means entirely closed in and no other box or case is therefore necessary.
The terminals for connecting the line wires to the armature coil, may conveniently
he arranged on one of the end pieces.

page_text: The armature may be connected with a handle for operating it by partial or total
rotation in the several manners, described in specification No. 6893, 1888, filed by one
of the parties hereto, or it may be furnished with a milled head fixed to its axis
whereby a spinning motion may readily be imparted to it, a small fly wheel being also
advantageously added to increase the momentum of the rotating parts or a wheel or
are furnished with a handle or other convenient means of turning it, may be arranged
to rotate on an axis in some cases conveniently perpendicular to the armature axis and
may gear by means of friction, teeth or a cord or belt with another wheel arranged on
the said armature axis, the two wheels being suitably proportioned so that a single
turn of that which is operated by the handle, will occasion several turns of the other
and consequently of the armature.

to the bell or signal that they operate by means of flexible wire as much of the latter
as is not for the time being in use may conveniently be wound upon a reel or bobbin,
forming the base of generator, bell or signal, this reel or bobbin may be either fixed
permanently to the said base or arranged so that in winding or unwinding the wire,
the whole apparatus is turned or fitted on a suitable vertical or other spindle or axis
fixed to a base, so that the bobbin or reel can rotate while the said base remains at
rest. A spring or catch may be employed to prevent the wheel rotating when not
employed or by generating friction to preclude its rotating with too great facility and
a spring may also be fitted tending always to rotate the wheel and wind up the flexible
wire with a catch to arrest the motion as required.

EDWARD Cox-WALKER Feethams, Darlington ALAN AROHIBALD CAMPBELL
SWINTON Electrical Engineer 66 Victoria Street London, S.W. do hereby declare
the nature of this invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
Our invention relates to improvements in magneto electric generators suitable for
actuating bells, indicators and other electrical signals, and in appliances for use in
connection therewith.
In accordance with our invention we employ an armature of the ordinary shuttle
form or any suitable description, C. Figs. 1, 2 & 3 wound with conducting wire, D
and arranged between the two pole pieces B B of a permanent steel or other magnet
of the usual horseshoe or similar form A so that it can be rotated in the ordinary
manner.
We find it convenient to fashion the pole pieces B B, which should be of soft iron
each with a groove or slot in which the poles of the simple or compound magnet A
may be held, the pole pieces being of suitable form to admit of the armature being
placed with its axis parallel to the legs of the magnet so that this axis if continued
would pass through the yoke of the said magnet.
The armature axis D₁ may conveniently be supported in bearings formed in end
pieces F of brass or other suitable non-magnetic material, fastened across the poles of
the magnet from one pole piece to the other, these end pieces which may be con-
veniently fixed to the pole pieces by means of screws, serving also to keep the pole
pieces rigid and being conveniently fitted with feet F for the whole apparatus to
stand on, or for fixing the same where required or on to any base of wood or other
material that may be wanted.
The armature may conveniently be protected from dust or injury by two plates of
suitable material J J fitted to cover the spaces between the pole pieces, these plates
being fixed across the poles of the magnets on either side of the armature. The
armature is by this means entirely closed in and no other box or case is therefore
necessary.
The terminals H H' for connecting the line wires to the armature coil may
conveniently be arranged on one of the end pieces.
The armature may be connected with a handle E' for operating it by partial rotation
a stop G being provided to prevent too great a movement or it may be furnished with
a milled head fixed to its axis whereby a spinning motion may readily be imparted to
it, a small fly wheel being also advantageously added to increase the momentum of the
rotating parts, or a wheel or are E Fig. 4 furnished with a handle E³ or other
convenient means of turning it may be arranged to rotate on an axis perpendicular to
the armature axis and may gear by means of friction or teeth with another wheel E*

arranged on the said armature axis the two wheels being pressed together by a
spring as shewn and suitably proportioned so that a single turn of that which is
operated by the handle will occasion several turns of the other and consequently of
the armature.
When generators of these or similar constructions are made portable and connected
to the bell or signal that they operate by means of flexible wire as much of the latter
as is not for the time being in use may conveniently be wound upon a reel or bobbin
forming the base of generator, bell or signal.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
The several arrangements of magneto electric signalling apparatus substantially as
herein before described and illustrated.
