PROVISIONAL SPECIFICATION.
Improvements in Bed Pans and other Chamber Utensils or Receptacles
for Offensive Matters.
I, JOSHUA HENRY LAMPREY, of No. 1, Walburton Road, Brockley, in the
County of Kent, Literary Editor do hereby declare the nature of this invention
to be as follows:-
-
My invention consists in the improvements hereinafter described in bed pans
and other chamber utensils or receptacles for offensive matters the principal
object of my said improvements being to prevent escape of effluvium from offen-
sive matters contained in such utensils or receptacles. Other objects of my said
improvements applied to bed pans are to facilitate use thereof.
In constructing a bed pan according to my said invention I give to it a form
in plan approximating to that of a bicycle saddle and I close or cover in the
whole of the top or upper part except that which when the pan is in use is
immediately under the anus in which part of the cover I form an aperture
communicating with the interior of the pan and I make an elevation at the
rear of the upper part of the pan the form of which elevation somewhat resembles
that of the cantle of a saddle and I so fashion the said top part or seat of the
pan as to ensure in conjunction with the said elevation a determinate position of
the user on the pan and I form a moderate elevation at and near the forward
portion of the seat part for the purpose of retaining on the said part of the pan
any slight discharge of urine involuntarily occurring during defecation. Around
the orifice herein before referred to in the seat part of the pan I secure by suitable
means one end of a tube of india rubber the other end of which depends within
the interior of the pan and is so made as to be normally in a collapsed state and
to be capable of opening readily on the application of slight internal pressure.
Through the said tube the feces pass freely into the interior of the pan when it
is in use and by the collapsion of the lower part of the said tube after passage
through it of the fæces escape of effluvium from the matters within the pan is
prevented. To provide for closure of the upper portion of the said tube when
the pan is not in use I arrange a jointed and preferably spring actuated covering
plate or pad at the rear part of the pan. The normal position of this plate or
pad is over the mouth of the said tube but when the pan is about to be used the
said plate or pad is turned upward or backward in which position it is retained
by pressure of the body of the user. The mouth or upper part of the said tube
may however be closed when not in use by means of a removable stopper or by
other convenient means. I secure the said tube in the orifice in the pan by
engagement therewith of a flange or thickness at the upper end of the said tube
or by other convenient means. To admit of removal of the contents of the pan
and cleansing of the interior thereof I form at the rear or other convenient part
thereof an aperture furnished with a screw cap or stopper or other suitable
closure.
In applying my invention to chamber pots and the pans of commodes and

page_text: other like utensils I furnish them with covers formed and fitted with collapsing
tubes substantially as hereinbefore described with reference to bed pans and
provide the said covers with any convenient means for securing them to the
Eaid utensils in such manner as to preclude escape of effluvium.
In applying my invention to receptacles for offensive liquids only I provide in
any suitable manner for closure of such vessels and I secure 'to them collasping
tubes of the kind herein before described for passage of the liquids into the said
receptacles.
The inlet tubes instead of or in addition to being collapsible as hereinbefore
described may have at their discharge ends self closing valves capable of yielding
to very slight pressure.

Improvements in Bed Pans and other Chamber Utensils or Receptacles
for Offensive Matters.
I, JOSHUA HENRY LAMPREY, of No. 1, Walburton Road, Brockley, in the
County of Kent, Literary Editor 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:-
My invention consists in the improvements hereinafter described in bed pans
and other chamber utensils or receptacles for offensive matters the principal
object of my said improvements being to prevent escape of effluvium from offen-
sive matters contained in such utensils or receptacles. A. further object of my
said improvements as applied to bed pans is to facilitate use thereof.
In constructing a bed pan according to my said invention I give to it a form
in plan approximating to that of a bicycle saddle and I close or cover in the
whole of the top or upper part except that which when the pan is in use is
immediately under the anus in which part of the cover I form an aperture
communicating with the interior of the pan and I make an elevation at the
rear of the upper part of the pan the form of which elevation somewhat resembles
that of the cantle of a saddle and I so fashion the said top part or seat of the
pan as to ensure in conjunction with the said clevation a determinate position of
the user on the pan. Around the orifice herein before referred to in the seat part
of the pan I secure by suitable means one end of a tube of india rubber the
other end of which depends within the interior of the pan and is so made as to be
normally in a collapsed state and to be capable of opening readily on the applica-
tion of slight internal pressure. Through the said tube the feces pass freely into
the interior of the pan when it is in use and by the collapsion of the lower part
of the said tube after passage through it of the feces escape of effluvium from the
matters within the pan is prevented. The mouth or upper part of the said tube
may be closed when not in use by means of a removable stopper or by other
convenient means. I secure the said tube around the orifice in the pan by
engagement therewith of a flange or thickness at the upper end of the said tube
or by other convenient means. To admit of removal of the contents of the pan
and cleansing of the interior thereof I form at the rear or other convenient part
thereof an aperture to which may be applied a stopper or other suitable closure.
The pan may be made of earthenware, or enamelled metal or other convenient
.

page_text: material and the whole may be in one piece or the pan proper and the top or
cover thereof may be separable.
A bed pan constructed according to my invention and fitted with an inlet tube
acting as hereinbefore described and having the top or cover made in one with
the lower part is illustrated in Figures 1, 2 and 3 of the accompanying drawings.
Figure 1 being a plan view of the pan Figure 2 a section thereof taken on the
line A A Figure 1 and Figure 3 a section taken on the line BB Figure 1.
On examination of the drawing it will be seen that the general form of the
pan in plain view approximates to that of a bicycle saddle that is to say it is of
considerably less width at one end than the other the narrow end which is
marked a being the end which is foremost when the pan is in use; b is the top
or upper part of the pan on which the body rests when the pan is in use which
part is shaped to conform approximately to the part of the body to which the pan
is to be applied. e is the elevation at the rear of the upper part of the pan the
effect of which elevation conjointly with the shape described of the upper part
of the pan is to ensure a determinate position on the pan of the user thereof the
said position being such that the circular aperture in the top bis immediately
under the anus. is the india rubber tube through which the fœces pass into
the interior of the pan. As will be readily perceived on examination of Figures 2
and 3 the said rubber tube is supported in its place by engagement of a rim or
thickened edge at one of its ends in a depression around the aforesaid aperture
in the top of the pan and the part of the said tube depending within the pan is
collapsed or flattened at and near its end so as to constitute a valve permitting of
downward passage of the fæces into the pan and preventing escape of effluvium
from the interior of the pan. The means and operation by which an india
rubber tube of the shape illustrated and having the action I have described may
be produced are well known therefore it is unnecessary here to describe them.
e is a flanged ring of metal or other suitable material fitting within and over the
upper end of the said tube & the object of which ring is to prevent accidental
displacement of the said tube. f is the aperture provided for removal of the con-
tents of the pan and cleansing of its interior to which aperture when the pan is
required to be used any convenient means of closure such as a plug or stopper
of any suitable material is applied.
Figures 4, 5 and 6 of the accompanying drawings illustrate a bed pan con-
structed according to my invention with a separable top or cover. Figure 4 being
a plan and Figures 5 and 6 sections taken respectively on the lines CC and DD
Figure 4. In the said Figures 4, 5 and 6 such of the parts as correspond with
those already described with reference to Figures 1, 2 and 3 are marked with the
same letters of reference as in those figures.
Referring to the said Figures 4, 5 and 6 g is the pan proper which is furnished
with a handle h and to which the cover is connected by engagement of a flange i
thereon with a groove in the upper edge of the pan g. When the pan is
required to be used the flange i of the cover is dipped in water and then engaged
in the groovej as shown in the drawing the small quantity of water adhering to
the said flange being sufficient to seal the junction of the parts and thus prevent
escape of effluvium from the pan. The india rubber tube d is secured in place by
engagement thereof around a flange projecting from the underside of the
cover b around the circular aperture therein.
In applying my invention to chamber pots and the pans of commodes and
other like utensils I furnish them with covers formed and fitted with collapsing
inlet tubes substantially as hereinbefore described with reference to bed pans
and I provide the said covers with any convenient means for preluding escape of
effluvium. For instance I secure or connect a ring of india rubber to such a
part of the cover that when the latter is in place on the receptacle or vessel the
said ring of india rubber is compressed between them.
In applying my invention to receptacles for offensive liquids only I secure to
the inlets thereof collapsing tubes of the kind hereinbefore described for passage

page_text: of the liquids into the said receptacles. Or for this purpose the inlet tubes
instead of being collapsible as hereinbefore described may have at their discharge
ends self closing apertures having the action of valves capable of yielding to very
slight pressure from within the tubes and preventing passage of vapour or gases
from the vessel to which they are applied. A tube having a self closing aperture
capable of thus acting is illustrated in section in Figure 7 of the accompanying
drawings in which figure the said aperture is marked 7.
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 I
claim:-
First: A bed pan the whole of the top of which is closed or covered in except
at the part which when the pan is in use is immediately under the anus of the
user.
Secondly: A bed pan having a top or cover shaped to approximately fit the
part of the body which rests on the pan when in use.
Thirdly: The combination with a bed pan having a closed or covered top in
which is an aperture for passage of the feces into the pan of an india rubber
tube one end of which is applied or secured to the said aperture and the other
end of which is normally in a collapsed state and is capable of opening readily
on the application of slight internal pressure.
Fourthly: The improvements hereinbefore described in chamber pots and
the pans of commodes and other like utensils which improvements consist in
furnishing the same with a cover shaped to approximately fit the posterior part of
the human-body-and having an aperture for passage of faeces to which aperture is
secured one end of an india rubber tube the other end of which is normally in a
collapsed state and is capable of opening readily on the application of slight
internal pressure.
Fifthly: The improvements herein before described in receptacles for offensive
liquids which improvements consist in the combination with the inlets thereof
of collapsing or self closing tubes of the kinds hereinbefore described and illus-
trated in the accompanying drawings for the purpose and substantially as herein-
before described.
