PROVISIONAL SPECIFICATION.
Improvements in Bed Warming Apparatus and Arrangements.
ALFRED CHARLES BROWN of 129 Algernon Road Lewisham in the County of
London Engineer, and GEORGE RICHARD NEILSON of 112 Tulse Hill Lambeth in
the County of London Secretary to Public Company do hereby declare the nature
of this invention to be as follows:-
These improvements consist in making India Rubber or other flexible material
hot water containers for warming beds or couches etc. in the shape of long tubes,
win closed ends and fitted with suitably stoppered filling orifices and capable of
extending right across the foot and up the great part of both the sides of the bed,
so as to exclude cold draughts and warm the air which enters, instead of in the
simple bottle or other compact shapes used at present which only warm one
place.
We may also aflix at intervals along the length of such tubular hot water con-
tainers either hooks or eyes or other similar couplings capable of engaging with
counterparts to be affixed to the bed-clothes, or safety pins capable of fixing
thereinto so as to maintain the tubes in their proper desired positions.
The tubes may also be enclosed in a casing of canvas, cloth or similar material
to increase their strength, and may also be covered with velvet, plush, flannel or
other textile material for making them of more attractive appearance.
The tubes may also be extended so as to completely surround the bed, preferably
inside the clothes, and their ends may then instead of being closed, be attached
to a small boiler or hot liquid container, each end at a different vertical level,
so that a continuous circulation shall be established through the tube arising from
the greater specific gravity of the cooling liquid, causing a flow from the higher
attached end to the lower.
Thus an even and equable temperature is maintained in the tube for a long time
without requiring an abnormally high temperature at the commencement, and
smaller tubes may be used.
The boiler may have a small lamp or gas flame underneath to maintain the
temperature and may then itself be small, but preferably tall vertically, or it may
consist of a coiled metal tube, or a larger container may be used capable of holding
a sufficient body of hot water or other liquid to maintain the temperature as long as
required without further or continuous heating.
In either case the boiler or container may conveniently hang on the foot of the
bed-stead, or stand on a tripod or other stand near thereto.
Or for the same purposes in Hotels, Hospitals, &c., the ends of the bed flexible
warming tubes may be attached to the fixed metallic circulating pipes or other
convenient parts of an ordinary hot water system where such exists, in any such
way that a circulation of hot liquid shall be caused to flow through the flexible
bed-warming tubes.

ALFRED CHARLES BROWN of 129 Algernon Road Lewisham in the County of
London Engineer, and GEORGE RICHARD NEILSON of 112 Tulse Hill Lambeth in
the County of London Secretary to Public Company 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:-
These improvements consist in making india rubber or other flexible material
hot water containers for warming beds or couches etc. in the shape of long tubes,
with closed ends and fitted with suitably stoppered filling orifices and capable of
extending right across the foot and up the great part of both sides of the bed, so
as to exclude cold draughts and warm the air which enters, instead of in the
simple bottle or other compact shapes used at present which only warm one place.
We may also affix at intervals along the length of the tubular hot water con-
tainers either hooks or eyes or other similar couplings capable of engaging with
counterparts to be affixed to the clothes, or safety pins capable of fixing thereinto
so as to maintain the tubes in their proper desired positions.
The tubes applied in either of the ways described in this Specification may also
be enclosed in a casing of canvas, cloth, or similar material to increase their
strength, and may also be covered with velvet, plush, flannel or other textile
material for making them of more attractive appearance and more comfortable.
In the drawings Fig. 1 is a side view of such a tubular warmer, A. A., shewn
broken, to reduce the length. Safety pins are shewn at LL attached to cords
encircling the tube, or they may be sewn or attached to a flannel or other outer
covering of the tube, or other kinds of attachments may be used as described
above. M shews a screw stopper, screwing into and closing a filling orifice in a
metal or ebonite end piece, inserted and tied or cemented into the flexible tube A,
the other end of which is closed without an orifice.
The tubes may also be extended so as to completely surround the bed or couch,
preferably inside the clothes, or bent or coiled in such a way as to conveniently
apply heat to other portions of clothing or heating pads for application to the
body, and their ends may then, instead of being closed, be attached to a small
boiler, or liquid heater or hot liquid container, each end at a different vertical
level, so that a continuous circulation shall be established through the tube arising
from the greater specific gravity of the cooling liquid, causing a flow through the
flexible tube from the higher attached end to the lower.
Thus an even and equable temperature is maintained in the tube for a long time
without requiring an abnormally high temperature at the commencement, and
smaller tubes may be used.
Figs. 2 and 3 are respectively front and side elevations (partly shewn in section)
of such an arrangement, the flexible tube being again shewn broken in Fig. 2 to
reduce the length and omitted in Fig. 3 for clearness. In these figs. B shews
the boiler or liquid heater, attached by suitable brackets CC or otherwise to the
base board D or an equivalent framing and heated by a small ordinary lamp E,
dropped into a ring 1, or otherwise firmly fixed to the base board or framing.
K shews a screw stopper screwing into a filling orifice in B and clamping down on
to packing washer. H and I are respectively the inlet and outlet tules to
which the ends of the flexible tube are attached. A sliding bent or part tubular
shield piece having a lot to pass the inlet tube H when rotated into line with
it comes down on to the upper surface of the lamp and by rotating under tube H
This
forms a bayonet joint lock to keep the lamp in place, and shield the flame.

page_text: piece is bent into a somewhat larger diameter than the tube B, but has vertical
corrugations or internal ribs (shewn in Fig. 3) to take a bearing thereon and it
thus causes the hot gases to escape at the top vertically and close round the
heater tube B. Or the liquid heater may be otherwise constructed or may consist
of a coiled metal tube and may be operated by a small gas flame or night light
candle or other source of heat placed thereunder instead of a lamp as shewn.
Or instead of a liquid heater a large container may be used, capable of holding
a sufficient body of hot water or other liquid to maintain the temperature as long
as required without further or continuous heating.
This container may be of similar form to the heater B but made larger and
without the lamp.
In either case the liquid heater or container may conveniently hang on the
foot of a bed-stead, as by the straps and buckles shewn at JJ, Fig. 3, or stand
on a tripod or other stand.
such
Or for the same purposes in Hotels, Hospitals etc., the ends of the flexible
warming tubes may be attached to the fixed metallic circulating pipes or other
convenient parts of an ordinary hot water system, where such exists, in any
way that a circulation of hot liquid shall be caused to flow through the flexible
warming tubes.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. An India Rubber or other flexible material Hot Water Container, made in
the form of a long tube, capable of extending along the bottom and partly up
the sides of a bed as and for the purposes above described.
2. The attachment to such flexible tubular hot water container at intervals
along its length of hooks or eyes, safety pins or other similar convenient fixings
to maintain the correct position of such tube in a bed or among clothing.
3. A flexible tubular warmer having its ends attached to a small boiler or other
liquid heater or hot liquid container at different vertical levels or in any other
way so that a circulation is caused there-through.
4. A flexible tubular warmer as above described having its ends attached to the
pipes or other parts of an existing or permanent hot water system in such way that
a circulation of hot liquid shall be produced or caused through the flexible tubes.
5. The covering or enclosing of flexible warming tubes with, or in, flannel,
plush or other similar material as above described.
