PROVISIONAL SPECIFICATION.
An Improved Machine or Apparatus for Making Earthenware Sinks
and the like.
I, BENJAMIN ROBINSON, of Church Gresley, in the County of Derby, Sanitary
Ware Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to make earthenware sinks and other similarly
shaped articles by means of a continuous process in a similar manner to that in
which wire cut bricks and the like are made, so as to expedite the manufacture
of such sinks or the like.
In carrying out my invention I employ a horizontal worm and casing and
method of feed similar to that of a machine for making wire cut bricks, the
die being preferably of the same size as the external transverse dimensions of the
sink to be produced: a movable centre is arranged a short distance inwards from
the mouth of the die and a sliding face plate is arranged to butt up to the said
die. The clay being fed forward by the worm fills up the space between the mov-
able centre and face plate and so forms one end of the sink, the face plate is
provided with a horizontal rod or its equivalent bearing against a crank, the said
crank is now turned and allows the force of the machine to push forward the face
plate, which is provided with balance weights arranged and attached thereto in
any suitable manner; the clay now passes between the movable centre and sides
and bottom of the die, the body of the sink being thus formed and travelling along
on its bottom side upon any suitable bed with or without rollers or the like until
the face plate reaches a suitable stop; before it reaches this stop however the
movable centre is raised or otherwise removed from the die and the full body of
clay comes forward through the die and completes the other end of the sink or
the like which is now cut off by means of a wire or its equivalent and removed
from the machine: the face plate is now brought back by means of the balance
weights or their equivalent and the movable centre lowered or otherwise placed
in position and the operation repeated.
Any number and arrangement of suitable guide rods or the like may employed
to steady the face plate in its operation.
Suitable ornamentation, such as flutings, or the like, may be imprinted on the
sink after it has been thus made if desired.
I may arrange for the movable centre to be removed and replaced automati-
cally if desired from the sliding face plate when it reaches a certain point or
points.
Although the machine is herein before described as a continuously feeding clay
machine I do not wish this to be taken in a literal sense as I may find it con-
venient to slightly or wholly check the feed at certain points in the formation
of the sink or the like.

and the like.
I, BENJAMIN ROBINSON, of Church, Gresley in the County of Derby, Sanitary
Ware Manufacturer, 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 my invention is to make earthenware sinks and other similarly
shaped articles by means of a continuous process in a similar manner to that in
which wire cut bricks and the like are made, so as to expedite the manufacture
of such sinks or the like.
In describing my said invention reference will be had to the accompanying
sheet of drawings upon which :-
Figure 1 is a vertical section on line a, a of Figure 3.
Figure 2 is a half transverse section of my improved machine or apparatus on
line b, b of Figure 3.
Figure 3 is a half plan and half section on line c, c of Figure 1.
Figure 4 is a similar view to Figure 1 with a sink shewn formed as will be
hereinafter explained.
In carrying out my invention I employ a horizontal worm and casing and
method of feed similar to that of a machine for making wire cut bricks, the worm
and casing and method of feed being of any well known type are not shewn upon
the drawings, the die A being preferably of the same size as the external trans-
verse dimensions of the sink to be produced is provided with a distributing
centre O; a movable centre B is arranged a short distance inwards from the
mouth of the die and a sliding face plate C is arranged to come a short distance
behind the movable centre. The clay being fed forward by the worm in the
direction of the arrows fills up the space between the movable centre B and face
plate C and so forms one end of the sink, the face plate is provided with a hori-
zontal rod D or its equivalent bearing against a crank E, the said crank is now
turned and allows the force of the worm and body of clay to push forward the
face plate C, which is provided with balance weights F arranged to work over
pulley G and attached thereto in any suitable manner as at G¹; the clay now
passes between the movable centre B and sides and bottom of the die A, the body
of the sink being thus formed and travelling along on its bottom side by means
of pulleys H and lathed band J or other suitable bed with or without rollers or
the like until the face plate reaches a suitable position as shewn in Figure 4 the
sink being here shewn by letters N; before it reaches this position however the
movable centre B is raised or otherwise removed from the die and the full body
of clay comes forward through the die and completes the other end of the sink
or the like which is now cut off where shewn by dotted line on Figure 4 by means
of a wire or its equivalent and removed from the machine; the face plate C is
now brought back by means of the balance weights or their equivalent (partly
assisted by the turning of the crank) and the movable centre B lowered or other-
wise placed in position and the operation repeated.
Any number and arrangement of suitable guide rods K and rollers L or the
like may be employed to steady the face plate in its operation I may also arrange
the small plates M, M', to support the sink end and gauge its thickness; the
plate M moves away with the sink and air is admitted through the passages M².
Suitable ornamentation, such as fluting, or the like, may be imprinted on the
sink after it has been thus made if desired.

page_text: I may arrange for the movable centre to be removed and replaced automatically
if desired from the sliding face plate when it reaches a certain point or points.
Although the machine is hereinbefore described as a continuously feeding clay
machine I do not wish this to be taken in a literal sense as I may find it con-
venient to slightly or wholly check the feed at certain points in the formation
of the sink or the like.
Any well known lubricating device may be used in connection with the die for
facilitating the passage of the clay.
Just as the sink is being finished and immediately before it is cut off and when
the full body of clay is coming through the die I may, to prevent undue friction
and to prevent bulging in the end of the sink through pressure of the full body
of clay, have an arrangement of wedges P P to be operated in any suitable
manner and cause the sides of the die to slightly expand, these wedges being
closed again immediately the sink is cut off, ready for the passage of the next
sink.
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. In a machine or apparatus for making earthenware sinks and the like the
combination of a continuously or intermittently feeding clay machine having a
distributing centre O with a device or apparatus for forming sinks consisting of
a die with a depending adjustable and movable centre a movable sliding face plate
with rod and crank or other stop and suitable guiding rods or their equivalent,
balance weights, roller or other bed and cutting off device, substantially as
described an illustrated.
2. In a machine or apparatus for making earthenware sinks and the like the
combination of a continuously and intermittently feeding clay machine having a
distributing centre with a device or apparatus for forming sinks consisting of
a die having sides capable of expansion such as by a device of wedges P P¹
operated in any suitable manner, a depending adjustable and movable centre, a
movable sliding face plate with rod and crank or other stop and suitable guiding
rods or their equivalent, balance weights, roller or other bed and cutting off levice
substantially as described and illustrated.
