Year: 1869

page_text: LETTERS PATENT to Ferdinand Vauderaey, of Uccle, Belgium, for the
Invention of "IMPROVEMENTS IN APPARATUS FOR THE MANUFACTURE OF
BRICKS AND OTHER ARTICLES MOULDED OR FORMED FROM CLAYS AND OTHER
PLASTIC MATERIAL."
Sealed the 30th July 1869, and dated the 3rd February 1869.
PROVISIONAL SPECIFICATION left by the said Ferdinand Vauderasy
at the Office of the Commissioners of Patents, with his Petition,
on the 3rd February 1869.
I, FERDINAND VAUDERAEY, of Uccle, Belgium, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR THE
MANUFACTURE OF BRICKS AND OTHER ARTICLES MOULDED OR FORMED FROM CLAYS
AND OTHER PLASTIC MATERIAL," to be as follows:-
The object of my Invention is to construct a machine for moulding
bricks and other plastic materials whereby bricks and other articles can
be made of clay as dug from the ground and a continuous supply
furnished ready for removal for drying and burning.

page_text: The Invention consists of a pug mill of the ordinary construction
mounted above a series of moulds which are placed in a circular or
rectangular framing. The clay or other material is forced down to the
lower part of the pug mill, where it enters moulds carried upon a
circular table, which has a rotary motion communicated to it in any
suitable manner. Beneath the table a wheel or drum is placed, upon
which the bottom of the moulds are brought to bear in their rotation.
This wheel causes the moulds to rise so as to bring the upper surface
against the under side of a fixed table or plank. In this operation the
clay becomes compressed within the mould. The moulds with the material
within them then pass on towards a second wheel or drum, by which the
bottom of the mould is lifted, so as to cause the moulded article to
project beyond the top of its mould; it can then be removed to a drying
stack, or if the clay is sufficiently free from moisture it can be stacked or
otherwise treating for burning.
The machine may be mounted on wheels to enable it to be moved
from place to place. In place of the wheels or drums inclined plates
may be used to cause the moulds to rise.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Ferdinand Vauderaey in the Great Seal Patent
Office on the 3rd August 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FERDINAND
VAUDERAEY, of Uccle, Belgium, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of February, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Ferdinand Vauderaey, Her special licenco
that I, the said Ferdinand Vauderney my executors, administrators, and
assigns, or such others as I, the said Ferdinand Vauderacy, my executors,
administrators, and assigns, should at any time agree with, and no others
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel

page_text: Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS
FOR THE MANUFACTURE OF BRICKS AND OTHER ARTICLES MOULDED OR FORMED FROM
CLAYS AND OTHER PLASTIC MATERIAL," upon the condition (amongst others)
that I, the said Ferdinand Vauderaey, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Ferdinand Vauderaey, do hereby.
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, reference being had to the Drawings
hereunto annexed, that is to say:-
The object of my Invention is to construct a machine for moulding
bricks and other plastic materials whereby bricks and other articles can
be made of clay as dug from the ground and a continuous supply
furnished ready for removal for drying and burning.
The Invention consists of a pug mill of the ordinary construction
mounted above a series of moulds which are placed in a circular or
rectangular framing. The clay or other material is forced down to the
lower part of the pug mill, where it enters moulds carried upon a
circular table, which has a rotary motion communicated to it in any
suitable manner. Beneath the table a wheel or drum is .placed, upon
which the bottoms of the moulds are brought to bear in their rotation.
This wheel causes the moulds to rise so as to bring the upper surface
against the under side of a fixed table or plank. In this operation the
clay becomes compressed within the mould. The moulds with the
material within them then pass on towards a second wheel or drum, by
which the bottom of the mould is lifted, so as to cause the moulded
article to project beyond the top of its mould; it can then be removed to
a drying stack, or if the clay is sufficiently free from moisture it can be
stacked or otherwise treated for burning.
The machine may be mounted on wheels to enable it to be moved
from one place to another. In place of the wheels or drums inclined
plates may be used to cause the moulds to rise.

page_text: Figures 1 and 2 of the accompanying Drawings, which are respectively
a side elevation and a plan, illustrate the manner in which I propose to
carry my Invention into effect.
a, a, is the main frame of the machine, which can be mounted upon
wheels b, b, to enable it to be moved from place to place, or it may be
fixed in a building or under a cover of any kind; c, c, are pillars or
columns for supporting the pug mill d of ordinary construction, but with
the spindle of the blades e fitted in a horizontal manner in the lower part
of the mill. Upon the upper edge of the mill a hopper f is fitted for
receiving the clay or other material under operation. The blades or
agitators of the mill are caused to revolve while the machine is at work
by means of pinions g, g, being driven by a bevil wheel h receiving its
motion from another bevil wheel i fitted on the shaft j, which is
actuated through the spur gearing k, l, leading from the prime moving
pulley m. The spur pinion is likewise in gear with the large wheel n,
the spindle of which carries a disc p, in which five or any other
number of recesses or grooves are cut or formed in the periphery.
is a circular table mounted on the axes q' of the machine. The said
table q carries a series of brick moulds or boxes, each of which is
furnished with a moveable bottom, which rests partly on the bottom edge
of the said boxes and partly by a stem or rod projecting from the under
side thereof on a circular rail fixed underneath. This circular rail has
one portion of it much higher than the other portion, the incline
between the two levels occurring just beneath the fixed table or plank t.
As the disc p revolves the recesses or grooves in its periphery are
brought in succession against the stems or rods projecting from the
moveable bottoms of the moulds, forcing them upwards and compressing
the clay (which entered the moulds by the pug mill) between the
moveable bottoms of the said moulds and the fixed board t, at the same
time causing the circular table to rotate partially, carrying the moulds
round a certain distance, the stems of the moveable bottoms of the said
moulds advancing along the rail & till they are lifted by the drum s¹ to
such a height as to cause the moulded article to project beyond the top
of its mould, when it can be removed. In some cases I make the table
or plank & moveable up and down in a frame, and cause a lever arm u to
bear upon it with the required degree of pressure for insuring the proper
compression of the clay. The manner in which this pressure is regulated
is shown in the Drawings. I hinge one end of the lever u to the side of

page_text: the pug mill, and carry a rod down from its other end to the weighted
long arm or beam w which is centred on the fulcrum pin at x. Any
number of weights y on the end of the long arm to may be suspended in
order to obtain the necessary degree of pressure. When the clay has
been compressed the table moves round another distance or step, and the
stems on the bottoms of the boxes are lifted by the drum or wheel s¹ to
such a height as to cause the green brick or cake to protrude above the
level of the table to enable an attendant to remove it, or it may be lifted
by riding upon another incline upon the plate 8.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim,-
Firstly. The general construction, combination, and arrangement of
apparatus for moulding bricks and other articles from clays and other
plastic substances, in the manner herein-before described and represented
in the Drawings hereunto annexed.
Secondly. The employment of moveable bottoms to the mould boxes
actuated in the manner and for the purpose herein-before described and
represented in the annexed Drawings.
And, thirdly. I claim the employment of the fixed table or plank above
the mould boxes, as and for the purpose herein-before described and
represented in the accompanying Drawings.
In witness whereof, I, the said Ferdinand Vauderaey, have hereunto
set my hand and seal, this Thirty-first day of July One thousand
eight hundred and sixty-nine.
