IMPROVEMENTS IN MAGNETIC THERAPEUTIC PLASTERS
Year: 1872

page_text: LETTERS PATENT to Philip William Seymour, of Surrey Lane, Batter-
sea, in the County of Surrey, for the Invention of " IMPROVEMENTS
IN MAGNETIC THERAPEUTIC PLASTERS."
Sealed the 27th May 1873, and dated the 29th November 1872.
PROVISIONAL SPECIFICATION left by the said Philip William Seymour
at the Office of the Commissioners of Patents, with his Petition,.
on the 29th November 1872.
I, PHILIP WILLIAM SEYMOUR, of Surrey Lane, Battersea, in the
County of Surrey, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MAGNETIC THERAPEUTIC PLASTERS," to be as follows:-
This Invention has for its object improvements in magnetic thera-
peutic plasters. For this purpose I spread upon any suitable fabric,
woven or otherwise, a thin layer of composition, consisting preferably of
iron or steel filings and any suitable adhesive compound or compounds:
The adhesive compound which I prefer for this purpose consists
of pitch or other resinous material and india-rubber, but any other

page_text: adhesive materials may be employed in lieu thereof.
Over this
layer of magnetic composition I lay another thin sheet of fabric, and
this I cause to adhere thereto by the application of gentle heat and
pressure. Or tissue or other thin paper. may be used in lieu thereof so
that by applying a slight amount of heat thereto the plaster will be
rendered adhesive and will readily adhere to the body by reason of the
adhesive composition permeating through the covering of paper or other
thin material employed. The object of employing this layer of fabric
is to prevent oxidation of the metallic particles, and also to avoid any
deleterious effects which might otherwise arise from the metallic
elements being brought into immediate contact with the body. Or,
instead of employing a woven fabric for this purpose a thin coating of
simple adhesive material, such as is used in ordinary adhesive plasters
may be employed.
Another mode of forming these plasters is by employing strips or
pieces of iron or steel magnetized, in lieu of the iron or steel filings, as
previously described, this latter form I prefer to employ when a more
powerful appliance is required.
In some cases instead of using the composition as above explained
it may be preferable to spread a layer of adhesive material on to the
woven or other fabric used as a backing or base, and afterwards the
steel or iron filings may be applied in a layer and pressed thereon, after
which a thin coating of the adhesive material may be employed to act
as a protecting material, and also as a means of causing the magnetic
plaster to adhere to the body. In all cases I prefer to magnetize the
metallic ingredients after they are applied to the backing or base, and
the means employed for magnetizing the same in no way differ from
those heretofore employed for similar purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Philip William Seymour in the Great Seal Patent 3
Office on the 29th May 1873.
Office on the 29th May 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PHILIP
WILLIAM SEYMOUR, of Surrey Lane, Battersea, in the County of Surrey,
send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of November, 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 suc-
cessors, give and grant unto me, the said Philip William Seymour,
Her special license that I, the said Philip William Seymour, my cxe-
cutors, administrators, and assigns, or such others as I, the said
Philip William Seymour, 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, excrcise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN MAGNETIC THERAPEUTIC PLASTERS,"
upon the condition (amongst others) that I, the said Philip William
Seymour, 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 Scal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Philip William Seymour, 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 has for its object improvements in magnetic therapeutic
plasters. For this purpose I spread upon any suitable fabric, woven or
otherwise, a thin layer of composition, consisting preferably of iron
or steel filings and any suitable adhesive compound or compounds. The
adhesive compound which I prefer for this purpose consists of pitch or
other resinous material and india-rubber, but any other adhesive materials
may be employed in lieu thereof. Over this layer of magnetic com-
position I lay another thin sheet of fabric, and this I cause to adliere
thereto by the application of gentle heat and pressure. Or tissue or
other thin paper may be used in lieu thereof, so that by applying a
slight amount of heat thereto the plaster will be rendered adhesive, and
will readily adhere to the body by reason of the adhesive composition
permeating through the covering of paper or other thin material
employed. The object of employing this layer of fabric is to prevent

page_text: oxidation of the metallic particles, and also to avoid any deleterious
effects which might otherwise arise from the metallic clements being
brought into immediate contact with the body. Or instead of employing
a woven fabric for this purpose a thin coating of simple adhesive material,
such as is used in ordinary adhesive plasters, may be employed.
Another mode of forming these plasters is by employing strips or
pieces of iron or steel, magnetized, in lieu of the iron or steel filings as
previously described, this latter form I prefer to employ when a more
powerful appliance is required. In some cases instead of using the
composition as above explained it may be preferable to spread a layer
of adhesive material on to the woven or other fabric used as a backing
or base, and afterwards the steel or iron filings may be applied in a
layer and pressed thereon, after which a thin coating of the adhesive
material may be employed to act both as a protecting material and also
as a means of causing the magnetic plaster to adhere to the body. If
desired these plasters may be perforated in a similar manner to those
known as Allcock's porous plasters, whilst the surface which comes into
contact with the body may be suitably medicated. In all cases I prefer
to magnetize the metallic ingredients after they are applied to the
backing or base, and the means employed for magnetizing the same in
no way differ from those previously employed for similar purposes.
Having thus described the nature of my said Invention and the mode
in which I carry the same into effect, I would have it understood that
what I claim is the manufacture of magnetic therapeutic plasters
protected in manner substantially as herein described.
In witness whereof, I, the said Philip William Seymour, have
hereunto set my hand and seal, this Twenty-eighth day of May,
in the year of our Lord One thousand eight hundred and seventy-
three.
