PROVISIONAL SPECIFICATION.
Improved Machine or Apparatus for Making Earthenware Sinks and
the like.
We, ARTHUR SABINE and TIMOTHY SABINE of The Vulcan Ironworks, Swadlin-
cote in the County of Derby, Engineers, do hereby declare the nature of this
invention to be as follows:-
The object of our invention is to make earthenware sinks and other similar
flat bottomed goods through a die in a somewhat similar manner to that in which
socketted drain pipes are manufactured. These sinks have hitherto been made
with a press or by hand upon a block or in a mould; this is rather a lengthy
process and our invention is designed for making such articles more expeditiously.
In carrying out our invention we cause the clay or rather plastic substance to
be fed down to a die as in a machine for making socketted sanitary pipes and
in some respects our present apparatus will not be unlike the machine described
in our Letters Patent No. 16545 of 1895. We employ a vertically movable plat-
form as therein stated and upon this we place a centre core, which if desired may
be hinged to the platform. Around this core is arranged a moulding box, any
suitable means being provided for placing the core centrally of the said moulding
hox, the latter is attached to the die plate with certain vertical play as hereinafter
explained.
The clay being fed down through the die plate, passes into the moulding box
and directly it begins to ooze out through air holes or outlets between the mould-
ing box and die plate or moulding box and platform a crank or other device
is turned or operated and the platform descends with the core; this allows the
moulding box to descend until stopped (on any suitable stops) sufficiently far
to allow a wire or other cutting off device to pass between the underside of the
die plate and the top of the moulding box, a board having been first placed under
the sink thus cut off, to receive it, it is then expelled from the die and taken
away. The table may now be raised with the core and the whole is ready for
the formation of another sink.
It will be seen that the bottom of the sink is always made and may be of any
desired thickness the wire cutting the clay in two as already stated between the
die plate and moulding box.
The foregoing description applies to plain sinks, but we may ornament the
sides or ends by employing plates or the like inside the moulding box mounted
upon rods or their equivalents which pass to the outside and are there set up
with springs tending to keep the ornamental plates off the sides of the sink,
when the moulding box is full of clay these plates are pressed inwards by any
suitable means imparting their impressions to the sides or ends of the sink and
immediately upon being released return to the sides of the moulding box. We
may thus make plain and ornamental sinks with the same apparatus, and the
ornamental plates may be made interchangeable.

page_text: Different sized moulding boxes and cores would of course be required for
different sized sinks and as already indicated our invention may be applied to
the formation of any similar articles to sinks such as flower pots and troughs
of various kinds.

Improved Machine or Apparatus for Making Earthenware Sinks, and
the like.
We, ARTHUR SABINE and TIMOTHY SABINE of The Vulcan Iron Works, Swadlin-
cote in the County of Derby, Engineers, 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:-
The object of our invention is to make earthenware sinks and other similar
flat bottomed goods through a die in a somewhat similar manner to that in which
socketted drain pipes are manufactured. These sinks have hitherto been made
with a press or by hand upon a block or in a mould; these are rather lengthy
processes and our invention is designed for making such articles more
expeditiously.
In describing our invention reference will be had to the accompanying sheet
of Drawings upon which Figure 1 is a vertical section upon line a-a of Figure 2
shewing our invention as applied to a machine similar to those for making
sanitary pipes. Figure 2 is a plan on line b-b of Figure 1.
In carrying out our invention we cause the clay or other plastic substance to
be fed down to a die as in a machine for making socketted sanitary pipes and
in some respects our present apparatus will not be unlike the machine described
in our Letters Patent No. 16545 of 1895. We employ a vertically movable plat-
form A as therein stated and upon this we place a centre core B, which if desired
may be hinged to the platform or formed solid with it, or, as shewn upon the
Drawings may be a separate loose piece; around this core is arranged a mould-
ing box C, any suitable means being provided for placing the core centrally of
the said moulding box, such as forming a recess D in the platform A as shewn.
The top of the moulding box is bolted to the die plate E the two parts con-
stituting the die of the machine.
The clay being fed down through the die plate E, passes into the moulding
box and directly it begins to ooze out through the air holes or outlets at For
between moulding box and platform, a crank G or other device is turned or
operated and the platform A descends with the core B; this allows the moulding
box to descend until stopped (on any convenient stops H) sufficiently far to allow
a wire or other cutting off device to pass between the underside of the die and
the top of the moulding box at F, a board having been first placed under the sink
thus cut off, to receive it. A flange may be arranged all round the top of the
moulding box if desired as shewn by dotted lines at J on Figure 1 to receive this
board which may be recessed to fit thereon and which may also carry a skeleton
drum to fit accurately inside the sink, any suitable means being employed to
ensure the said drum being placed centrally underneath the moulding box.
The sink thus formed is carried away with the skeleton die inside it to the drying
shed where it is turned over on the bottom to dry and the drum is withdrawn.

page_text: The platform A may now be raised with the core and the whole is ready for
the formation of another sink.
It will be seen that the bottom of the sink is always made and may be of any
desired thickness the wire cutting the clay in two as already stated between the
die plate and the moulding box.
The foregoing description applies to plain sinks, but we may ornament the
sides or ends by employing plates K or the like inside the moulding box mounted
upon rods L or their equivalents which pass to the outside and are set up with
springs M bearing upon flanges N on the rods L and upon flanges O on the
moulding box, these tend to keep the ornamental plates off the sides of the sink,
when the moulding box is full of clay these plates are pressed inwards by any
suitable means imparting their impressions, to the sides or ends of the sink and
immediately upon being released return to the sides or ends of the moulding
box. We may thus make plain and ornamental sinks with the same apparatus
and the ornamental plates may be made interchangeable.
Plain flutings made be imprinted in the sides of the sinks by simply forming
corresponding projections P on the sides of the moulding box and a strengthening
flange such as Q may be arranged round the moulding box if desired.
Different sized moulding boxes and cores would of course be required for
different sized sinks and as already indicated our invention may be applied to the
formation of any similar articles to sinks, such as flower pots and troughs of
various kinds.
The core B may be perforated at the top (as shewn on Figure 1) and covered
with canvas so as to allow the air to escape.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:
In the manufacture of sinks and other similar goods the employment of a
continuously feeding clay machine in combination with a self centreing core B
and moulding box C the latter being provided with means for impressing and
otherwise ornamenting the sides or ends of the aforesaid sinks or the like, sub-
stantially as described and illustrated.
