PROVISIONAL SPECIFICATION.
Improvements in Sinks, more especially intended for use in Hospitals
as a Slop Sink, and for Washing or Cleansing Bed-pans or other
analogous articles.
I, SAMUEL STEVENS HELLYER, of 21 Newcastle Street, Strand, in the County
of Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention has for its object to provide a sink which is fitted not only for use
as a slop sink, but also for the ready washing or cleansing of articles, such for
instance as bed pans or urinal vessels, and is more especially intended for use in
hospitals or other places where a number of such articles require to be washed or
cleansed, and it is desirable to obviate the necessity for manual cleansing in cases
where it is desirable to avoid danger of the matter from the pans or the like
coming into contact with the person.
According to my invention the sink is made of any suitable form in general
configuration, but preferably of somewhat conical form with the smaller part down-
wards, and with a narrower portion projecting from the side for the reception of
the hand of the person using the sink when placing the article to be cleansed in its
position. The upper part of the sink has a flushing rim extending around its top
to which water is admitted so as to flush down the sides of the sink. There are
also inlets to the interior of the sink in any suitable number for the inlet of jets or
sprays of water, which can be turned on as desired so as to cleanse the articles
placed in the sink for the purpose. These inlets or the sink itself may be provided
with means for supporting the articles or retaining them in position to enable the
jets or sprays of water to efficiently act upon them; for instance, the inlet may
project into the sink and terminate in a nozzle for receiving the orifice of a urinal
vessel and for bed-pans, the sink may be provided with inclined rests or supports
which may be formed with rubber, or other suitable material and be arranged
conically so as to support pans of different sizes, above an inlet for water entering
and projecting from the lower part of the sink and provided with a reticulated or
perforated top or jets by which the water is sprayed or injected forcibly into
the interior of the pan resting in an inverted position in the said supports. The
outlet for the flushing water and other matter may be provided with a junction for
the attachment of the pipe leading to the waste pipe or drain and there may
intervene any suitable trap. The bottom of the sink preferably slopes down
towards the outlet to expedite the passing away of matter from the sink. The
sink may be supported upon legs or a pedestal or be supported in any other
suitable way.

Improvements in Sinks, more especially intended for use in Hospitals
as a Slop Sink, and for Washing or Cleansing Bed-pans or other
analogous articles.
I, SAMUEL STEVENS HELLYER of 21 Newcastle Street, Strand, in the County
of Middlesex, Engineer 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 has for its object to provide a sink, which is fitted, not only for use
as a slop-sink, but also for the ready washing, or cleansing, of articles such for
instance as bed-pans, or urine vessels, and is more especially intended for use in
hospitals, or other places where a number of such articles require to be washed, or
cleansed, as it obviates the necessity for manual cleansing particularly in cases
where it is desirable to avoid danger of infectious matter from the pans, or the like,
coming into contact with the person.
I will describe my invention with reference to the accompanying drawings,
premising however that I do not restrict it to the shape, and details of construction,
shewn and described, as variations may be made therein without departing from the
nature of my invention.
Figures 1 and 2 are sections at right angles to each other of a sink made according
to my invention and Figure 3 is a plan of the same.
The body A, of the sink may be made of any suitable form, but I preferably
make it somewhat conical with the smaller part downwards as shewn and with a
narrower portion A2 at one side for the reception of the hands of the persons using
the sink when placing the articles to be cleansed in position therein.
The upper part of the sink has a flushing rim B extending around its top to
which rim water is admitted as required by either, or both, of the pipes B' B' one
of which inlets may be dispensed with if desired.
The water, entering the rim B, passes therefrom through slots, or openings, b,
and effectually flushes the interior of the sink.
There are also inlets to the interior of the sink, as at C, and D, (any desired
number of these inlets may be provided) through which the water can be ejected
as desired so as to cleanse the articles placed in the sink for the purpose. The
water can be supplied to the several inlets from a suitable flushing cistern or cisterns
or other source of water supply either cold or hot or both. The inlets C. D may
be provided with means for supporting the articles and retaining them in position
to enable the jets or sprays of water to efficiently act upon them for instance the
inlet C may project into the sink and terminate in a nozzle suitably shaped to enter
the orifice of the urine vessel E. In the drawing the urine vessel E is shewn
supported on a frame F removeably attached to the body of the sink so as to admit
of frames, or supports, of different sizes and shapes being fitted to suit different
articles to be cleaned.
For supporting bed pans the sink is preferably provided in the interior with ribs
rests or supports G which may be of any suitable material, such for example as
rubber, attached to, and arranged conically on, the interior surface of the sink so as
to support, in the required position, pans of different sizes. Projecting from the
lower part of the sink is the water inlet D which is preferably provided with a
reticulated or perforated top or nozzle d by which the water is sprayed, or injected,
forcibly into the interior of the bed pan H resting in an inverted position on the
supports G. The outlet I for the flushing water and other matter from the sink is
preferably provided with a junction J with a spigot or flanged end for its attachment
to the pipe leading to the waste pipe, or drain, or, preferably, there is provided,
between the outlet I and the pipe leading to the drain, any suitable trap such for
example as shewn at K. The bottom of the sink preferably slopes down as shewn

page_text: at a towards the outlet I to expedite the passing away of matter from the sink.
The sink may be supported upon legs or on a pedestal L as shewn or be supported
in any other suitable way for instance by a bracket from a wall.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In sinks the combination of supports for holding articles to be cleansed with
means for injecting a jet or jets of water into the said articles when so held sub-
stantially as hereinbefore described.
2. In sinks the combination of strips or ribs of rubber or analogous relatively
soft material conically disposed so as to constitute supports for articles to be cleansed
substantially as hereinbefore described.
3. The arrangement and combination of parts constituting the sink substantially
as hereinbefore described and illustrated in the accompanying drawings.
