Year: 1872

page_text: LETTERS PATENT to William Darlow, of North Woolwich Road,
Canning Town, in the County of Essex, for the Invention of "Im-
PROVEMENTS IN PORTABLE MAGNETO APPARATUS FOR CURATIVE AND OTHER
DDY TA
MID AMD "
PROVISIONAL SPECIFICATION left by the said William Darlow at
the Office of the Commissioners of Patents, with his Petition, on
the 31st October 1872.
I, WILLIAM DARLOW, of North Woolwich Road, Canning Town, in
the County of Essex, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN PORTABLE MAGNETO APPARATUS FOR CURATIVE AND OTHER
PURPOSES, AND IN THE MODE OF APPLYING THE SAME," to be as follows:-
This Invention relates, first, to improvements in making portable
magnets by cutting thin sheet or other steel into suitable shapes, in
order that the poles of the magnets may be made to act readily one upon
the other, and so complete the magnetic circuit or circuits; or in cases

page_text: where it is not convenient to bring the poles of the magnets into such a
position, I connect or complete the magnetic circuit by means of soft
iron keepers suspended mechanically, and kept in the desired position by
india-rubber, or other elastic or flexible material. Portable magnets
may also be formed according to my improvements either round or oval
shaped.
Another part of my improvements consists in placing the poles of
portable magnets in a bed or covering of soft iron filings, so as to pre-
serve and increase their power by conducting the magnetism from one to
the other pole of the magnet, thus keeping up the circulating and
cumulative power of the magnet or magnets.
Another part of my improvements consists in coating portable magnets
by galvanizing them in the ordinary method with zinc or other inoxidiz-
able metal, and thus prevent the magnets from corrosion by perspiration,
damp atmosphere, and other causes.
Another part of my improvements consists in coating portable mag-
nets and keepers (of soft iron or soft iron filings) in or with india-rubber,
leather, or other flexible or elastic material suitable for the purpose,
either with or without the magnets and keepers being first galvanized,
provided that the india-rubber or gummy material or fabric is sufficient
to protect it from corrosion or oxidation.
The second part of my improvements relates to a more convenient
method of applying portable magnets to the body and intensifying the
magnetic power, and according to this part of my improvements horse-
shoe or other shaped magnets may be laid overlapping each other, and
jointed together by a hinge from the centre, so that the substance or
material on which they are placed may be bent without altering the
polarization of the magnets, the joint or hinge to be made of india-rubber
or other suitable substance, or to be bolted or tied together by wire
cords or other fastenings.
According to this part of my improvements portable magnets are
placed with their opposite poles one to the other, and jointed or con-
nected together as before described, or in any convenient way, so as to
form a complete magnetic circuit. This may be done by placing two
horse-shoe or other shaped magnets pole to pole, or by building up a
circuit of bar magnets.

page_text: My improvements also relate to the placing of portable bar magnets
one above the other, so as to make small magnetic batteries, each end of
the battery being connected by keepers, as herein-before described.
Also in placing bar magnets of different lengths and widths one over
the other, the narrowest and longest bar being in the center, then
covering the whole battery of magnets with soft iron filings to complete
the magnetic circuit.
Also in covering the whole of a portable magnet or magnets with
leather, india-rubber, or other flexible matter, material, or fabric, so that
they may be readily adapted to belts, bands, bandages, or be attached to
the garments of the wearer.
Also in applying portable magnets, covered or galvanized, to trusses,
the poles of the magnets being suitably arranged for this purpose.
In all cases where the magnets do not form keepers to themselves, the
magnets are provided with keepers of soft iron, or laid on or in a bed,
and covered with soft iron filings, the magnets not forming a keeper in
themselves.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Darlow in the Great Seal Patent Office
on the 30th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
DARLOW, of North Woolwich Road, Canning Town, in the County of
Essex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of October, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Darlow, Her special license
that I, the said William Darlow, my executors, administrators, and
assigns, or such others as I, the said William Darlow, 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

page_text: Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
PORTABLE MAGNETO APPARATUS FOR CURATIVE AND OTHER PURPOSES, AND IN THE
MODE OF APPLYING THE SAME," upon the condition (amongst others) that I,
the said William Darlow, my executors or administrators, by an in-
strument 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.
NOW KNOW YE, that I, the said William Darlow, 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 :-
This Invention relates, first, to improvements in making portable
magnets by cutting thin sheet or other steel into suitable shapes, in order
that the poles of the magnets may be made to act readily one upon the
other, and so complete the magnetic circuit or circuits, as illustrated by
Figure 1 of the Drawing hereunto annexed; a, a, being a pair of magnets
without a keeper or keepers, and b, b, another pair of magnets with
keepers c, c, between them. The magnets are shown as embedded in or
combined with a strip d of india-rubber or other suitable flexible
material. I prefer to employ a compound known as "magnetine" for
the keepers c, c. In cases where it is not convenient to bring the poles
of the magnets into such a position as that before referred to, I connect
or complete the magnetic circuit by means of soft iron keepers suspended
mechanically and kept in the desired position by india-rubber or other
elastic or flexible material, as shown at Figure 2. Portable magnets
may be formed according to my improvements either round or oval
shaped, by preference in sets e, as shown in Figure 3.
Another part of my improvements consists in placing the poles of
portable magnets in a bed or covering of soft iron filings, so as to pre-
serve and increase their power by conducting the magnetism from one to
the other pole of the magnet, thus keeping up the circulating and
cumulative power of the magnet or magnets.
Another part of my improvements consists in coating portable mag-
nets by galvanizing them in the ordinary method with zinc or other

page_text: inoxidizable metal, and thus prevent the magnets from corrosion by
perspiration, damp atmosphere, and other causes.
Another part of my improvements consists in coating portable magnets
and keepers (of soft iron or soft iron filings) in or with india-rubber,
leather; or other flexible or elastic material suitable for the purpose,
either with or without the magnets and keepers being first galvanized,
provided that the india-rubber or gummy material or fabric is sufficient
to protect it from corrosion or oxidation.
The second part of my improvements relates to a more convenient
method of applying portable magnets to the body and intensifying the
magnetic power, and according to this part of my improvements horse-
shoe or other shaped magnets a may be laid overlapping each other, and
jointed together by a hinge from the centre, as shown at Figure 4 of the
Drawing, so that the substance or material on which they are placed may
be bent without altering the polarization of the magnets, the joint or
hinge to be made of india-rubber or other suitable substance, or to be
bolted or tied together by wire cords or other fastenings.
According to this part of my improvements portable magnets a are
placed with their opposite poles one to the other, as shown at Figure 5,
and jointed or connected together as before described, or in any con-
venient way, so as to form a complete magnetic circuit. This may be
done by placing two horse-shoe or other shaped magnets pole to pole, as
shewn in Figure 1, or by building up a circuit of bar magnets a, as shown
in Figure 6.
My improvements also relate to the placing of portable bar magnets a
one above the other, so as to make small magnetic batteries, as shewn at
Figure 7, each end of the battery being connected by soft iron or mag-
netine keepers, as herein-before described.
Also in placing bar magnets of different lengths and widths one over
the other, the narrowest and longest bar being in the centre, as shown at
Figure 7, then covering the whole battery of magnets with soft iron
filings or with magnetine keepers as before stated, to complete the
magnetic circuit.
Also in covering the whole of a portable magnet or magnets, such as
previously described, with leather, india-rubber, or other flexible matter,
material, or fabric, so that they may be readily adapted to belts, bands,
bandages, or be attached to the garments of the wearer.

page_text: Also in applying portable magnets, covered or galvanized, to trusses,
the poles of the magnets being suitably arranged for this purpose.
In all cases where the magnets do not form keepers to themselves,
the magnets, according to my improvements, are provided with keepers
of soft iron or magnetine, or are laid on or in a bed of soft iron filings or
borings, or covered with the same or other magnetic conductor, the
magnets not forming a keeper in themselves.
In witness whereof, I, the said William Darlow, have hereunto
set my hand and seal, this Twenty-ninth day of April, in the year
of our Lord One thousand eight hundred and seventy-three..
WILLIAM DARLOW. (L.S.)
