PROVISIONAL SPECIFICATION.
An Improved Die for Making Earthenware Pipes, Chimney Pots,
and the like.
We, ARTHUR SABINE and TIMOTHY SABINE of The Vulcan Works,
Swadlincote, 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 construct a new or improved die for making
earthenware pipes, or the like.
In carrying out our said invention we form the said die of brass or any other
suitable metal, and make the centre core cone-shaped or of any other suitable
shape hollow as to the centre, and perforated or slotted, then we cover this
perforated core with canvas, or any suitable material again surrounding the said
canvas with a perforated metal cylinder. Cast to the metal core top and bottom
are two rings, also a movable metal ring near the bottom of the cone.
The top
ring is cone-shaped and is raised above the perforated metal cylinder before
mentioned, in order to prevent the said perforated metal cylinder from wearing
away. The next metal ring is made movable and is so placed near the bottom of
the cone to break up the clay and make it part with the various liquids and gases
and also to prepare the way to the bottom ring, which forms the shape of the clay
pipe and also gives it surface as it leaves the die. Then we form the inside of the
mould of the die plate, also perforated or slotted, and internally lined with canvas
and again finally lined with a perforated metal cylinder. The whole of these
perforated metal cylinders are made movable also the canvas, in order that they
may be readily cleaned. The top of the die plate also has a movable ring of metal
to facilitate cleaning. We do not tie ourselves to a circular shaped die.
The object of this invention is to get rid of various liquids and gases contained
in clay and to prevent blebs in pipes. As the clay is forced through the die the
liquids and gases escape internally through the perforations of the hollow centre
cone, and externally through the perforations of the die plate mould to the outside.
This treatment prevents the pipe blebbing when drying.

COMPLETE SPECIFICATION.
An Improved Die for Making Earthenware Pipes, Chimney Pots,
and the like.
We, ARTHUR SABINE and TIMOTHY SABINE, of The Vulcan Works,
Swadlincote, 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 construct a new or improved die, for making
earthenware pipes chimney pots and the like, which will assist in extracting the
various liquids and gases contained in the clay or material of which the said pipes,
[ Price 8.1.

page_text: chimney pots or the like are formed, and prevent the same from blebbing in the
after processes of drying and baking.
In describing our invention reference will be had to the accompanying sheet of
drawings which will be deemed to form a part of this Specification.
Figure 1 being a vertical section on line "a." "a." of Figure 2, and Figure 2 a
plan on line "b." "b." of Figure 1.
In carrying out our said invention we form the said die of brass or any other suitable
metal or material and make the centre core A, of a cone or other suitable shape,
hollow as to the centre and perforated or slotted; concentric with this core we
place a finely perforated metal casing or casings B, B1, between which and the
perforated centre core A is a space K in which we place a substance of canvas or
other suitable absorbent and porous material. Cast or fixed to the metal core A
in any suitable manner, at the top and bottom of the same are two rings or
projections C, C', also a movable metal ring D near the bottom of the core. The
top ring is cone-shaped and projects beyond the perforated metal casing B before
mentioned in order to prevent the said perforated metal casing from wearing away.
The next metal ring is made movable and is so placed near the bottom of the core
as to break up the clay and make it part with the various liquids and gases, and
also to prepare the way to the bottom ring C, which forms the shape of the clay
pipe, chimney pot or the like and also gives it surface as it leaves the die at E.
The die plate is also perforated as at G or slotted, and is provided with an
internal finely perforated metal casing I the space I between which and the die
plate F is filled or packed with canvas or other suitable absorbent and porous
material. These perforated metal casings and canvas or other packing material
are made movable in order that the parts may be readily cleaned. The top of the
die plate also has a movable ring of metal J to facilitate cleaning and removing
the parts. We do not bind ourselves to a circular or any other shaped die, the
circular one being shewn on the accompanying sheet of drawings for the sake of
illustration only.
As the clay or other plastic substance is forced through the die in the direction
of the arrows the liquids and gases escape internally through the finely perforated
metal casings B, B', canvas or other screening or absorbent material and the inner
core A; and externally the finely perforated casings H, canvas or the like in
space I and perforations G in the die plate F.
We may introduce additional rings upon the central core A if desired, and wish
it to be understood that we do not bind ourselves to the number or position of them
as shewn upon the accompanying sheet of drawings.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The improved die for making earthenware pipes, chimney pots and the like,
consisting of a perforated central core A with outer findly perforated casing or
casings B, B', the space K being adapted to be filled or contain canvas or other
absorbent or screening material or substance; rings C, C, and D), the perforated
die plate F with finely perforated inner casing H and space I, the latter being
adapted to be filled or contain canvas or other absorbent or screening material or
substance, and the movable ring J, substantially as and for the purposes described
and illustrated.
