PROVISIONAL SPECIFICATION.
Improved Construction of Closet-pans, Lavatory-basins, Slop-sinks,
Baths and similar Vessels.
I, JOHN JARVIS, 29, Bradwell Lane, Wolstanton, Stoke-on-Trent, Sanitary-
Pottery Manager, do hereby declare the nature of this invention to be as
follows:-
This my invention has reference to an improved construction of closet-pans,
lavatory-basins, plug-basins, slop-sinks and baths made of or from earthenware
which have an overflow orifice or orifices, the object of my said invention being to
prevent grease, dirt or other objectionable matter which invariably floats on the
surface of water passing to such orifice, to screen such orifices from view, and
to strengthen such articles.
In carrying my said invention into practice I make a depending portion of
suitable thickness in one with such articles at a suitable distance from, or enclos
ing the top portion of the recess in which the overflow orifices or grids are
invariably formed, so that such depending portion will screen such orifices or
grids from view.
The mouth or entrance of such overflow orifices behind such depending portion
may be round, square, rectangular, elliptical or other suitable shape, or consist of
two or more suitably shaped orifices forming a pattern or design.
It will be readily understood that when too much water has been allowed to
run into, or poured into such vessels, the excess quantity will pass up behind the
depending portion formed on such vessels and out through the overflow orifices,
and as the surface of such excess water lowers or sinks, all or nearly all the
grease, dirt or soap-froth on its surface will be prevented by the said depend-
ing portion from passing to and through such overflow orifices or grid.
Dated this 23rd day of December 1899.

Improved Construction of Closet-pans, Lavatory-basins, Slop-sinks,
Baths and similar Vessels.
I, JOIN JARVIS, 29, Bradwell Lane, Wolstanton, Stoke-on-Trent, Sanitary-
Pottery Manager, do hereby declare the nature of this invention and in what
[Price 8d1

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
-
This my invention has reference to an improved construction of lavatory
basins, slop-sinks, baths, plug-bowls, urinals and like similar vessels having an
overflow orifice or orifices and made of or from earthenware or like similar
suitable fictile material, the object of my said invention being to screen such
overflow orifices from view and prevent grease, dirt and other objectionable
matter which may float on the surface of water or other liquid placed in, poured
in, or allowed to flow into such vessels from passing to such overflow orifices.
In carrying my said invention into practice I first make a mould of suitable
size and shape of or from plaster of Paris of the interior of such vessels
by carving and moulding in the ordinary way which for basins, plug-basins,
lavatory-basins and the like vessels I call a basin-block, in the back portion of
such mould-block I form a recess of suitable shape in which I fit a detachable
portion made of or from plaster of Paris having two or more straight and per-
pendicular, vee-shaped or like similar suitable grooves of suitable size formed
therein for fitting against suitably shaped matches or projections of similar
shape formed on or at the lower end of the said recess to ensure such detachable
portion fitting in proper position in such recess.
I first mould a lavatory-basin of or from earthenware or prepared clay in the
ordinary way on such mould block, the outside surface of its detachable portion
forming a recess on the inner surface of the back wall of the moulded-basin,
I then by means of a suitably shaped knife, or a suitably shaped piece of wood or
metal form a suitably shaped slot or aperture of suitable size in the back wall
of such moulded basin directly behind the projecting portion or "lip" whilst
such moulded basin is in a clay or green state on such plaster-mould, and then
fix or adhere by means of "slip" whilst in a clay state one end of a suitably
shaped earthenware overflow pipe of suitable size which has been separately
moulded to the outer surface of the back-wall of such lavatory-basin so as to
cover such slot or aperture. When lifting the moulded-basin from its mould-
block, the detachable portion in the back of such mould-block which forms a recess
in the back portion of such basins is lifted from or removed from such mould-
block at the same time, after turning the moulded basin the right-way up, or right
way uppermost the said detachable portion of the mould-block can be readily re-
moved from such moulded basin, I then by means of a suitably shaped knife, or a
suitably shaped piece of wood or metal form an orifice or slots of suitable shape
and size in such moulded basin between the downwardly projecting portion or
lip" and the recessed portion of the backwall of such moulded basins whilst
in a clay state, to enable water or other liquid to pass into the overflow pipe
from such basins. Such overflow pipe may be fixed to such basins, whilst
such basins are on their mould, or be fixed to such basins after removal from their
mould. Such moulded basins may be afterwards dried, fired, decorated, glazed
and again fired, or be left plain, dried, glazed and fired.
In order that my said invention may be more readily understood and explained
in detail I have hereunto annexed a sheet of drawings on which letters of refer-
ence are marked shewing a moulded earthenware basin, and a plaster mould for
use in making such vessels, according to my invention.
DESCRIPTION OF DRAWINGS.
Figure 1 is a plan view of a lavatory basin made according to my invention.
Figure 2 is a side elevation of Figure 1 looking in the direction indicated by
arrow A.
Figure 3 is a cantional alevation taken on the lin D

page_text: basin taken on the line H-I of Figure 1 looking in the direction indicated by
arrow A.
Figure 5 is a side elevation of the plaster-mould I use in moulding or making
such lavatory basin.
Figure 6 is a plan view of Figure 5, and
Figure 7 is a similar plan view to Figure 6 with the detachable portion of
such mould removed therefrom.
On reference to the figures of the drawings hereto annexed a represents an
earthenware lavatory-basin known in the trade as a 20" x 16" which has been
formed or made in the usual way on the plaster mould illustrated at Figures 5,
6 and 7 which forms a downward projecting portion or "lip" c solid with the
back portion d or body of such basin.
33
While such moulded basin is in a green or clay state on such plaster mould I
take a suitably shaped knife, or a suitably shaped piece of wood or metal with
which I remove a portion of the backwall of such basin so as to form a suitably
shaped hole or orifice e therein directly behind or opposite the downwardly pro-
jecting portion or "lip" c, an then fix by means of slip one end of a suitably
shaped separately moulded earthenware over-flow pipe f, whilst in a green
state to the outer surface of the said backwall d so as to cover the said orifice e.
I then lift or remove such moulded basin a from its mould b and in so doing
lift or remove the detachable portion 2 away from the mould at the same time,
I then turn the moulded basin the right-way up into the position shewn at
Figures 2, 3 and 4 and then remove the portion 62 of the mould from the well or
interior of the basin, I then take a suitably shaped knife, a suitably shaped
piece of wood, metal or the like with which I form a suitably shaped hole or
orifice of desired size in the back portion of such basin between the down-
wardly projecting portion or "lip c and the back wall to form a passage into
the said over-flow pipe f from the well of such basin.
22
As before mentioned such overflow pipe f may be fixed by "slip" to such basin
whilst in a green state after such moulded basin has been removed from its
mould.
Such moulded earthenware basin may then be dried, fired, decorated, glazed
and then again fired, or be dried, fired, glazed, and again fired with plain surfaces.
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
I claim is :-
-
1. The construction of earthenware or like similar fictile closet-pans, lavatory-
basins, slop-sinks, plug-bowls, baths, urinals and similar vessels having an
overflow-orifice or overflow apertures with a downwardly projecting portion or
"lip c for screening such orifices from view as herein substantially described,
set forth and illustrated at Figures 3 and 4 of the drawings hereto annexed.
