Year: 1873

page_text: LETTERS PATENT to William Darlow and Henry Fairfax, both of
435, Strand, in the County of Middlesex, for the Invention of "Iм-
PROVEMENTS IN MAGNETO APPLIANCES AND IN MAGNETO-ELECTRIC APPARATUS
FOR CURATIVE AND OTHER PURPOSES."
Sealed the 15th May 1874, and dated the 18th November 1873.
PROVISIONAL SPECIFICATION left by the said William Darlow and
Henry Fairfax at the Office of the Commissioners of Patents, with
their Petition, on the 18th November 1873.
We, WILLIAM DARLOW and HENRY FAIRFAX, both 435, Strand, in
the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MAGNETO APPLIANCES AND IN MAGNETO-
ELECTRIC APPARATUS FOR CURATIVE AND OTHER PURPOSES," to be as follows:
Our Invention relates, first, to the protection and insulation of portable
magnets, so that although inflexible they may be readily applied to any
part of the body or to any garment without the necessity of the magnets
being made in any way flexible as heretofore. For this purpose we coat

page_text: the magnet with a thin non-conducting waterproof case or covering of
cloth, leather, paper, or other material which has been rendered water-
proof and impermiable to perspiration by varnish or otherwise, or by
covering the magnets with tin, lead, or other foil.
Another part of our improvements consists in placing the insulating 5
material, such as before described, so as to overlap in order that a
margin of the insulator shall thus be left, which will enable the
insulated magnet to be placed on and taken off a garment or other
appliance for the purpose of cleansing any number of times, or whenever
required, without injury to the garment or other appliance, or to the 1
insulated magnet.
Another part of our improvements consists in insulating the two poles
of the magnet in the manner before described and insulating the centre
portion by covering it with sealing wax or other suitable material, thus
combining the electrical property of the metallic insulator as far as 1
possible with the magnetic properties, or by wholly or partially covering
with either of the before named insulators as before described.
According to another part of our Invention the magnets insulated as
before described may be of corrugated or other form or shape so that
they can be plaited into or interlaced in any garment or appliance, 2
thereby dispensing with the necessity of securing them in position by
stitching or by cement or adhesive material.
According to another part of our improvements we prefer to render
the centre of the steel magnet soft, thereby intensifying the magnetic
power of the magnets at the poles, the soft portion of the magnets acting 2
as the conductor.
The second part of our Invention relates to improvements in the con-
struction of machines for the generation of currents of electricity by
forming a spiral of magnets which are caused to revolve by a spring and
clockwork mechanism or by hand, so as to act on a series of soft iron or 3
other magnetic conductors attached to or forming part of a brass or
other electrical conducting key-board or comb. This spiral may be
encased in a brass or other non-magnetic drum or cylinder, part of which
cylinder may be enameled with glass or other suitable enamel and
electrical rubbers fixed opposite to this part of the drum or cylinder, a
thus combining the frictional with the magneto-electric currents if
required. The soft iron may also be arranged in the form of a spiral or

page_text: on the cylinder and the permanent magnets placed on the key-board or
comb of conducting material, or the magnets or the soft iron may be
placed longitudinally on or otherwise in the cylinder or key-board as
may be required. One of the wires or conductors of the current is to
be affixed to the key-board or conducting material and the other to the
spiral or cylinder or drum.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Darlow and Henry Fairfax in the Great
Seal Patent Office on the 16th May 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
DARLOW and HENRY FAIRFAX, both of 435, Strand, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said William Darlow and Henry
Fairfax, Her special license that we, the said William Darlow and Henry
Fairfax, our executors, administrators, and assigns, or such others
as we, the said William Darlow and Henry Fairfax, our 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
MAGNETO APPLIANCES AND IN MAGNETO-ELECTRIC APPARATUS FOR CURATIVE AND
OTHER PURPOSES," upon the condition (amongst others) that we, the
said William Darlow and Henry Fairfax, our executors or administrators,
by an instrument in writing under our or their hands and seals, or
under the hand and seal of one of us or them, 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 we, the said William Darlow and Henry
Fairfax, 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 thereof, that is to say :—
Our Invention relates to the protection and insulation of portable
magnets, so that although inflexible they may be readily applied to any
part of the body or to any garment without the necessity of the magnets
being made in any way flexible as heretofore. For this purpose according
to one part of our improvements we coat or cover the magnet with a
thin non-conducting waterproof case or covering of cloth, leather, paper,
or other material which has been rendered waterproof and impermeable
to perspiration by varnish or otherwise, or we cover the magnets with
varnish, tin, lead, or other foil.
Another part of our improvements consists in placing the insulating
material such as before described, so as to overlap the edges of the
magnet enclosed therein, in order that a margin of the insulater shall
thus be left which will enable the insulated magnet to be stitched or
otherwise attached to or placed on and taken off a garment or other appli-
ance for the purpose of cleansing the garment or appliance any number
of times, or whenever required, without injury to the garment or other
appliance, or to the insulated magnet.
Figure 1 of the Drawing hereunto annexed shows a thin portable
magnet a enclosed in insulating fabric or material 6 with the edges over-
lapping the magnet a as previously described in accordance with our
improvements.
Another part of our improvements consists in insulating the two poles
of the magnet in the manner before described, and insulating the centre
portion by covering it with sealing wax or other suitable material, thus
combining the electrical property of the metallic insulator as far as
possible with the magnetic properties, or by wholly or partially covering
with either of the before named insulators as before described.
Figure 2 shows a portable magnet a with its two poles insulated as
previously described, the overlapping edges of the insulating material b
affording convenient means for stitching or otherwise attaching it to a
garment or other article in accordance with our improvements.
According to another part of our Invention the magnets insulated as
before described may be of corrugated or other form or shape so that

page_text: they can be plaited into or interlaced in any garment or appliance, thereby
dispensing with the necessity of securing them in position by stitching
or by cement or adhesive material.
According to another part of our improvements we prefer to render
the centre of the steel magnet soft, thereby intensifying the magnetic
power of the magnets at the poles, the soft portion of the magnets
acting as the conductor.
The second part of our Invention relates to improvements in the con-
struction of machines for the generation of currents of electricity by
forming a spiral of magnets, which spiral is caused to revolve by a spring
and clockwork mechanism or by hand, so as to act on a series of soft
iron or other magnetic conductors attached to or forming part of a brass
or other electrical conducting key-board, frame, or board.
In carrying out this part of our improvements the spiral of magnets
may be encased in a brass or other non-magnetic drum or cylinder, part
of which cylinder may be enamelled with glass or other suitable enamel,
and electrical rubbers fixed opposite to this part of the drum or cylinder,
thus combining the frictional with the magneto-electric currants if re-
quired. Or the soft iron magnetic conductors a, a, may, according to our
improvements, also be arranged in the form of a spiral as represented in
Figure 3 of the Drawing annexed or on the cylinder, and the permanent
magnets b, b, placed on the key-board or frame c of conducting material
(or the magnets or the soft iron may be placed longitudinally on or
otherwise in the cylinder frame or key-board as may be required). One
of the wires or conductors d, d, of the current is to be affixed to the key-
board c or conducting material, and the other to the spiral, or cylinder,
or drum.
In witness whereof, we, the said William Darlow and Henry Fairfax,
have hereunto set hand and seal, this Fifteenth day of May, in
the year of our Lord One thousand eight hundred and seventy-
foun
