1. This invention relates to improvement for protecting the body from contact
with urine and is especially adapted for the use of children and invalids.
constructing the said convenience mattress or cushion which may be made of any
suitable material the same is perforated so as to allow the matter urine from the
invalid or child to descend through some holes into a reservoir or receptacle
attached to the said mattress or cushion. I form a pad which is constructed with
an upper and lower chamber with with three sheets of rubber or waterproof.
The inside middle sheet with the top sheet are joined together around and form
the top compartment which is filled with wool, water or air. Also the middle
and top sheet are from place to place connected together the same is perforated,
so as to allow the water from the infant or the invalid to pass through freely
into the under compartment or reservoir which is formed with the second and
third sheet joined together closely around, leaving one side open to be emptied
and cleaned at will, and to prevent the upper compartment closing the lower
compartment. A frame or pan in china or enamel or any suitable substance is
inserted into the interior of the mattress so that the flow of water from the infant
or invalid into the reservoir or lower compartment cannot be stopped by the
weight of the infant or invalid. For the combined convenience any shape can
be given the size not limited, and can be made either long, round or square.
The perforated mattress or cushion can be made without the third sheet of water-
proof which forms the top only.
I do not limit myself to the exact details described, my invention will admit
of several modifications without departing from the true nature of my invention.

"An Improved Personal Sanitary Convenience for Invalids and
Children.
I, CELESTINE RUBENS, of 11, Barrow Road, Streatham Common, in the County of
Surrey, do hereby declare the nature of this invention. and in what manner the
!

page_text: same is to be performed to be particularly described and ascertained in and by
the following statement:-
This invention relates to improvement for protecting the body from contact
with urine and is especially adapted for the use of children and invalids.
In constructing the said convenience mattress or cushion which may be made
of any suitable material, the same is perforated so as to allow the urine or other
matter from the invalid or child to descend through some holes into a reservoir
or receptacle attached to or forming part of the said mattress or cushion. 1
form a pad which is preferably constructed with an upper and lower chamber
with three sheets of india rubber or waterproof material. The inside middle
sheet with the top sheet are joined together around their edges and are also
connected at intervals by eyelets which form passages or spaces, the intermediate
portions between the two sheets being filled with wool, air, water, or other
material as a stuffing. The perforations allow any water or other substance from
the infant or the invalid to pass through freely into the under compartment or
reservoir which is formed with the second and third sheet joined together closely
around three side edges leaving one side open, so that the substance can be
emptied and the compartment be cleaned at will and to prevent the upper com-
partment closing the lower compartment, a frame or pan in china or enamel, wire,
or any suitable substance is inserted into the compartment formed by the second
and third sheets, so that the flow of water from the infant or invalid into the
reservoir or lower compartment cannot be stopped by the weight of the infant
or invalid.
For the combined convenience any shape can be given, the size not limited,
and can be made either long, round, or square. The perforated mattress or
cushion can be made without the third sheet of waterproof.
My invention can be applied in various ways and may either be so constructed
to form part of the mattress or may be formed as a separate article and be applied
to a mattress, or the article can be made of the ordinary width of, say, a bed-
stead, and the ends be formed from ordinary mattress made to fit, with specially
constructed cushion, the bedstead of the size intended.
My invention will be understood from the several examples shown on the
annexed drawings.
Figure 1 is a section and Figure 2 a plan of a mattress (partly broken away)
to which my invention forms a part and extends completely across.
Figure 3 is a perspective elevation of an wire frame of the construction I
prefer to employ.
Figure 4 is a perspective view of a mattress with my invention applied to the
centre portion and forming part of the mattress, the figure also representing the
mode of emptying by a nurse into a pail, this construction being specially
applicable for infants cots.
Figure 5 is a section and Figure 6 a plan of a mattress (partly broken away)
in which my invention is applied to a hole or recess made in the mattress.
The cushion or portion of a mattress which constitutes my invention is formed
of three sheets of india rubber or other material, the top one A being connected
to the middle one B, all around their edges by sewing or otherwise and at
intervals by eyelets C or other like devices, or by sewing or otherwise but in
such manner that the parts connected together have perforations. The spaces D
between the connected parts are filled with the usual stuffing material, or it may
be air or water so as to extend the material at those parts to form projections,
so that any urine or other matter coming from the invalid or infant who is
resting upon the mattress will flow down into the recesses or hollows formed by
the connections or eyelets C and pass to the chamber E which is formed by the
bottom sheet F being connected to the middle sheet B at three of their edges,
the other edge of both sheets B and F projecting beyond the side of the mattress
that they can be folded up and buttoned, or otherwise secured to the mattress in
such manner as to retain any liquid or semi-liquid in the chamber.

page_text: To allow of the chamber E being always in proper condition for receiving the
liquid or semi-liquid, I insert therein a framework or pan preferably of the kind
shown at Figure 3, or in dotted lines Figure 6, this preventing the liquid from
being returned to the upper outside of the bed due to movement of the patient
or infant, the chamber being thereby kept intact.
When my cushion is applied to a mattress in the manner indicated by Figure 6,
I prefer to provide a projecting lip G all around the upper edge, so that same
can be secured by buttons H to the mattress portion and thus prevent a rucking
or unevenness at the meeting edges.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
1 claim is:
1. The improved sanitary convenience for invalids and children, consisting of
a perforated pad or mattress having a chamber or receptacle on the underside,
substantially as set forth.
2. Constructing a sanitary cushion or mattress from three sheets of waterproof
material, the two upper sheets being connected together at their edges and at
different parts of their surface, and provided with perforations at their connected
parts, the lower sheet being so connected to the middle sheet as to form a pocket
or chamber for collecting and retaining any liquid or semi-liquid passing through
the perforations, substantially as described and as shown on the annexed drawings.
