page_text: LETTERS PATENT to Cornelius Walton, of Bournemouth, in the County of
Hants, for an Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR PREPARING OR PUGGING CLAY OR OTHER MATERIALS, AND FOR MAKING
PRESSING, AND DELIVERING BRICKS, TILES, BLOCKS, LUMPS, OR OTHER
ARTICLES."
PROVISIONAL SPECIFICATION left by the said Cornelius Walton at the
Office of the Commissioners of Patents on the 3rd August 1881.
CORNELIUS WALTON, of Bournemouth, in the County of Hants. "IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR PREPARING OR PUGGING CLAY OR OTHER
MATERIALS, AND FOR MAKING, PRESSING, AND DELIVERING BRICKS, TILES, BLOCKS,
LUMPS, OR OTHER ARTICLES."
According to my Invention the clay or other materials are fed into a pugmill,
in the bottom of which are outlets through which the materials under treatment
pass into exchangeable dies or moulds of the shape, form, or size required. During
the operation of filling one die or mould I at the same time press the contents of
another die which has previously been filled in the same manner; the pressure is
applied from above and from below simultaneously.
After such pressure has been applied the pressed brick or other article is raised
to the level of the top of the die or mould, which is placed in a traversing or sliding
table;
during the motion of the sliding table the uplifted pressed brick or other
article is automatically removed towards one end of the sliding table, which there
acts as a delivery table.
During the removal of the pressed brick or other article from the die or mould
to the delivery table another die or mould is being simultaneously carried from
the position in which it is filled by the pugmill to the position where its contents
are subjected to the pressure, after which the same operation of emptying of
die and removal of pressed contents of die to delivery table is performed as already.
described.
To produce the pressure I employ cams and cranks, and to prevent breakage of
parts of the machine through the pressure of stones in the clay or over filling of
the die I employ springs which yield to any excess resistance caused by such stones
or over filling of the die.

by the said Cornelius Walton in the Great Seal Patent Office on the
3rd February 1882.
CORNELIUS WALTON, of Bournemouth, in the County of Hants. "IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR PREPARING OR PUGGING CLAY OR OTHER
MATERIALS, AND FOR MAKING, PRESSING, AND DELIVERING BRICKS, TILES,
BLOCKS, LUMPS, OR OTHER ARTICLES."
According to my Invention the clay or other materials are fed into a pug mill,
in the bottom of which are outlets through which the materials under treatment
pass into exchangeable dies or moulds of the shape, form, or size required. During
the operation of filling one die or mould I at the same time press the contents of
another die which has previously been filled in the same manner; the pressure is
applied from above and from below simultaneously.
After such pressure has been applied the pressed brick or other article is raised
to the level of the top of the die or mould, which is placed in a traversing or sliding
table; during the motion of the sliding table the uplifted pressed brick or other article
is automatically removed towards one end of the sliding table which there acts as
a delivery table.
During the removal of the pressed brick or other article from the die or mould
to the delivery table another die or mould is being simultaneously carried from
the position in which it is filled by the pug mill to the position where its contents
are subjected to the pressure, after which the same operation of emptying of
die and removal of pressed contents of die to delivery table is performed as already
described.
To produce the pressure I employ cams and cranks, and to prevent breakage of
parts of the machine through the presence of stones in the clay or overfilling of
the die I employ springs which yield to any excess resistance caused by such stones
or overfilling of the die.
In the accompanying Drawings I have shown a machine constructed according
to this Invention, Figure 1 being a part sectional side elevation; Figure 2, a part
sectional end elevation;-Figure-3-a-plan-shewing-the-sliding tables below the pug
mill; and Figure 4, a plan showing cam arrangement; Figure 5 is a vertical cross
section through the framing of the machine; Figure 6, a vertical cross section of
part of the machine through wheel gearing in lower part of machine; and Figure 7,
a similar section through bottom framing of machine. P is a pug mill of ordinary
construction mounted on the top of the machine framing and provided with a
vertical shaft P¹ which is mounted in a step bearing on bed plate Q¹ of the
machine, see Figure 7, and driven from the horizontal shaft R by bevil gearing R¹
and R. The pug mill has two outlet apertures B opposite to each other, and
there are two moulds or dies A, see Figure 3, which receive the clay or other
material therefrom; they are moved alternately in under the apertures B. The
sliding tables G containing the moulds A, Figure 3, are connected by rods B', and
the moulds are fixed in the top side of the sliding tables G working in guides G¹,
Figure 5, and moved laterally by a revolving cam E, Figures 1 and 3, mounted on
the upright pug mill shaft P1; when either of the moulds is thus moved into its
extreme position to the right or left respectively its contents are subjected to
pressure from above by a descending cross head C, Figures 1 and 2, which is
working in guides C¹ and is actuated by a rod L from a crank and crank pin M¹,
Figure 5, on one side, and by another rod L from a crank pin M in a spur
wheel M² on the other side, see Figure 4. The cranks and spur wheels are on the
cross shafts K, which by means of spur wheels on two short shafts which, by

page_text: bevil gear O¹, receive motion from the vertical pug mill shaft P', see Figure 6.
To prevent breakage from stone or other hard substance or from the die being
overfilled, I fit the cap of the lower head or end of each connecting rod L with a
strong spring N which enables the cross heads C to yield to such excess resistance.
The contents of the moulds are simultaneously exposed to pressure from below by
plungers S fitted with friction rollers S¹, which latter come in contact with
cams D on the cross shafts K.
The subsequent further upward motion of the
plunger and receding of the cross head C delivers the formed brick on the top of
the table G.
The mode of operation of the machine is as follows:-The clay is delivered
down through one of the two outlets B into one of the dies A, which, together
with the sliding table G, are moved laterally by the cam E; when one or other of
the moulds comes so far to the right or the left as to be under one of the cross-
heads C, this crosshead is depressed by the connecting rods L, at the same time
the corresponding plunger S is raised by the cam D, so that the clay in the mould
is compressed; by the continued rising of the plunger S and the receding of the
crosshead C the pressed form is forced up out of the mould A in the sliding
table G; at this moment this latter is moved back laterally, whereby the pressed
brick comes in contact with the part U on the side of the pug mill and remains
there until the sliding table returns to its first position, when the brick will be
carried along on the sliding table from which it is then taken off by hand or
otherwise.
And having thus described and ascertained the nature of this Invention, and the
mode in which it may be carried into effect, I declare that I claim,―
First. The combination of the following parts, viz. :-A pug mill or vessel having
two opposite bottom apertures, a table with two corresponding moulds adapted to
slide under said apertures, and two upper crossbeads and two lower plungers
adapted to alternately compress the material in the moulds and raise the brick
clear of the mould and support the brick until the mould has been moved laterally,
all substantially as described.
Second. The construction and combination of parts forming my improved
combined pug mill and brick or tile press operating as set forth, all substantially
as shown in the accompanying Drawings.
In witness whereof, I, the said Cornelius Walton, have hereunto set my hand
and seal, this Nineteenth day of January, in the year of our Lord One
thousand eight hundred and eighty two.
Signed, sealed, and delivered by
the said Cornelius Walton, in
