page_text: I, EDWARD PARKER DOVE, of No. 1, Leeds Road, Bradford, in the County of
York, Merchant, do hereby declare the nature of my invention to be as follows:-
This invention has for its object the construction of mattresses in such a manner
that they are more portable, healthier to sleep upon, and better ventilated than those
now in common use.
I accomplish my object by felting in the usual manner wool, using by preference
what is termed natural or undyed wool, which I felt into sheets of considerable
thickness and perforate the same at intervals for the purpose of ventilation.
Inserted in the body of the felt are a number of cords of linen or other fibrous
material placed both in a longitudinal and transverse direction for the purpose of binding
together the felt and thus to strengthen the thick felted material and enable it to retain
its shape.
In case of mattresses for medicated purposes, in lieu of the fibrous material, I insert
metallic wires previously magnetised, which as is well known have a beneficial
influence or effect on persons suffering from such complaints as epilepsy and kindred
disorders. When magnetic wires are inserted, instead of making the mattress of very
thick felted material, I prefer to accomplish my object by placing together two or
more sheets of felt, laying magnetised wires between them, and sewing or otherwise
attaching the sheets together, the same being perforated and the edges of the felt in
every case being protected and bound by suitable material, and the flat surfaces of the
mattress raised and made blanket like, and when in use supported by frame, across
which are stretched webs of linen, wire springs, or other suitable material in the same
manner as when arranged for supporting ordinary mattresses.
In order to destroy or prevent the presence of insects of any kind living in the
mattress, I soak the same in a solution of camphorated spirits or similar liquids.

Improvements in the Construction of Sanitary and Magnetic
Mattresses.
I, EDWARD PARKER DOVE, of No. 1, Leeds Road, Bradford, in the County of York,
Merchant, 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 :-
This invention has for its object the construction of mattresses in such a manner
that, they are more portable, healthier to sleep upon, and better ventilated than those
now in common use: and consists in felting wool into sheets, by preference using what is
termed natural or undyed wool; or the mattresses may be formed of wool combined
with other fibre such as jute, cotton, silk, and similar materials felted in the ordinary
manner into sheets of various thicknesses according to requirements, in every case,
when completed are provided with perforations through the same, which along with the
exterior may be coated with flexible waterproof material.
In order that my invention may be clearly understood, and readily carried into
effect, I now proceed to more fully describe the same, and for that purpose refer to
the several Figures hereunto annexed, the same letters of reference indicating
corresponding parts in all the Figures.
In the accompanying drawings. Fig. 1. represents a plan of the mattresses constructed
according to my invention, showing the perforations through the same, which may
be of any convenient configuration.
Fig. 2 is a section through lines a. b. and
Fig. 3. a section through lines c. d.
During the operation of felting which is carried out in the ordinary manner, I
insert in the body of the felt A. a number of cords B. of linen, or other fibrous
material placed both in a longitudinal and transverse direction for the purpose of
more effectually binding and strengthening the thick felted material A. and enabling
it to retain its shape.
In the case of mattresses for medicated purposes, I form the same with two or
more layers or sheets of felt A. and in lieu of the linen cords before-mentioned, or in
addition thereto, I place between each thin sheet of felt, metallic wires W. previously
magnetised, which as is well known have a beneficial influence, or effect, on persons
suffering from such complaints as epilepsy and kindred disorders.
The mattresses are in every case perforated for ventilation as at P. P. and when
two or more thin sheets of felt A. are used in forming a mattress, they are sewn or
otherwise attached together, the edges by preference being bound and protected by
suitable fabric or in lieu of the binding, the whole or a portion of the exterior along
with the perforated holes l'. may be coated with adhesive waterproofing applied to
the same in a similar manner as when waterproofing textile fabrics, so that in case a
mattress so covered and used for medicated or surgical purposes any liquid from the
patient will flow away through the perforations P. and the mattress readily washed or
cleaned without damage to the felted interior...

page_text: The mattresses may be supported in the ordinary manner by stretched webs or other
well known means, and in order to destroy, or prevent the presence of insects of any
kind in an uncovered or non-waterproof mattress, I soak the same in a solution of
camphorated spirits or similar liquids.
Having now particularly described and ascertained the nature of my invention, and
in what manner the same is to be performed, I declare that what I claim is :
1. The construction of perforated mattresses of felt, interspersed with cords of
fibrous material, or with metallic wires either separately, or in combination with the
cords of fibre.
2. The construction of perforated mattresses of felted material having the external
surfaces and perforations coated or covered with waterproof material applied
substantially in the manner described.
3. The construction of felted mattresses having perforations through the same for
the purpose of ventilation.
