PROVISIONAL SPECIFICATION.
An Improved Bed for Children and Invalids.
I, WILHELM STAAB, of 51 Karlstrasse Munich in the Empire of Germany
Jeweller do hereby declare the nature of this invention to be as follows:-
This invention consists in an improved bed for the use principally of young
children or other persons who from illness or otherwise are obliged to stay in bed
and the general object is to so construct the bed that any dampness arising for
instance from perspiration or from voiding of urine or other cause may pass away
from contact with the child or person occupying the bed and thus not give rise to
bedsores or other ailments or inconvenience. The improved bed may furthermore
be provided with means for warming it if desired.
On a suitable supporting frame work is stretched a wire mattress made of wire
which will not rust or be affected by such moisture as is likely to come in contact
therewith and over this mattress which forms a resilient support is a net work of
very elastic rubber made for instance by crossing a number of rubber tubes of small
diameter, or solid rods of rubber or pieces of a shape of section resembling an
inverted U placed. conveniently close together to leave interstices through which
liquid may pass down the whole resembling a net and being of very elastic and soft
texture so that the person lying thereon may be comfortable. If the net is made of
tubes these may be inflated with air, if the U shaped pieces are used the sides of
these are made very thin. A perforated sheet of soft india rubber may also be used
the connecting pieces of the sheet having running under them vertically standing
ribs so that the whole forms a soft cushioning surface.
Between the rubber surface sheet and the under wire mattress there may be
placed a soft coarse textured linen or other sheet to avoid draught passing up, or to
avoid soiling the mattress by excrementitious matter.
Under the mattress is placed a receiver for urine etc. the top being inclined
towards a hole therein whereby the urine may enter the interior of this receiver
through a syphon or equivalent device to prevent gases escaping.
If the bed is to be heated there is placed above the urine receiver but below the
inclined top thereof water tanks which may be filled with hot water so that the heat
radiating upwards warms the bed. These tanks should not extend under the part
of the bed where the head of the person will lie.

An Improved Bed for Children and Invalids.
1, WILHELM STAAB, of 51 Karlstrasse, Munich, in the Empire of Germany,
Jeweller, 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 consists in an improved bed for the use principally of young
children or other persons who from illness or otherwise are obliged to stay in bed,
and the general object is to so construct the bed that any dampness arising for
instance from perspiration or from voiding of urine or other cause may pass away
from contact with the child or person occupying the bed and thus not give rise to
bedsores or other ailments or inconvenience. The improved bed may furthermore
be provided with means for warming it if desired.

On a suitable supporting frame-work is stretched a wire mattress made of wire
which will not rust or be affected by such moisture as is likely to come in contact
therewith and over this mattress which forms a resilient support is a net work of
very elastic rubber made for instance by crossing a number of rubber tubes of small
diameter, or solid rods of rubber or pieces of a shape of section resembling an
inverted placed conveniently close together to leave interstices through which
liquid may pass down, the whole resembling a net and being of very elastic and soft
texture so that the person lying thereon may be comfortable. If the net is made of
tubes these may be inflated with air, if the U shaped pieces are used the sides of
these are made very thin A perforated sheet of soft india-rubber may also be used
the connecting pieces of the sheet having running under them vertically standing
ribs so that the whole forms a soft cushioning surface.
Between the rubber surface sheet and the under wire mattress there may be
placed a soft coarse textured linen or other sheet to avoid draught passing up, or to
avoid soiling the mattress by excrementitious matter.
Under the mattress is placed a receiver for urine, etc., the top being inclined
towards a hole therein whereby the urine may enter the interior of this receiver
through a syphon or equivalent device to prevent gases escaping.
If the bed is to be heated there is placed above the urine receiver, but below the
inclined top thereof, water tanks which may be filled with hot water so that the
heat radiating upwards warms the bed. These tanks should not extend under
the part of the bed where the head of the person will lie.
In the annexed drawing
Fig. 1 shows a longitudinal section of the bed and fittings thereof,
Fig. 2 is a plan view,
Fig. 3 is a perspective view of the rubber mattress and
Figs. 4 to 6 are alternative cross sections of the cross pieces of said mattress.
a is the frame, the elastic rust-proof wire mattress or netting.
This netting forms an elastic support for the covering mattress c which is made of
very soft elastic rubber. This rubber mattress is suitably composed of small pipes
of caoutchouc crossing or intersecting each other as shown by Fig. 2.
This rubber tubing mattress may be inflated with air so as to be rendered more
elastic.
Instead of making the base of small pipes of circular cross section as in Fig. 4,
square sectioned pipes may be used as in Fig. 6 or ledges or bars of semi-circular,
Ushape, or other suitable cross section as in Fig. 5. These ledges being open
below are rendered elastic by the yielding of their sides.
The said rubber mattress may also be made with a perforated surface of
caoutchouc or other water proof material S, Fig. 3, having on its lower side
yielding elastic ribs r.
The side walls of the pipes or ledges, and the ribs r are made as weak as possible
in order that they may easily yield to the pressure exerted by the weight of the
person lying thereon. d is the interposed piece of linen or any other suitable porous
material. is the reservoir below the wire-mattress b, its cover being formed with
the inclined planes e' leading to the opening o, through which urine flows into the
reservoir. This opening o is suitably closed by means of a syphon or other
arrangement of trapped pipes, or by water sealing, so that gases may not pass out
through it. A further purpose thereof is to avoid spilling the liquid in the reservoir
when moved.
In case warmth is desired, the reservoir is provided with one or more divisions, in
which hot water can be introduced. Fig. 1 shows the reservoir in section, provided
with such arrangement; division I receives the urine, division II the hot water.
For introducing the hot water, an opening is provided which may be closed, and at
the base of the other division I is a similar arrangement for removal of the urine
therein.
The arrangement is such that the water reservoir is placed above the urine
reservoir.

page_text: As shown in Fig.1 the hot water chamber does not extend under the place where
the head of the person reposes.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
I. An improved bed for children and invalids comprising in combination a
supporting mattress or frame made of wire-work and an upper mattress composed
of small elastic pipes, ledges, or bars of soft caoutchouc or the like having openings
therein, supported by said lower mattress and a reservoir beneath the latter adapted
to receive urine or liquid passing through said mattresses.
2. In the arrangement described in Claim 1, the construction of reservoir in such
manner that it may be fitted to produce warmth by arrangement of warm-water-
divisions, substantially as set forth.
