Year: 1873

page_text: LETTERS PATENT to William Edward Newton, of the Office for
Patents, 66, Chancery Lane, in the County of Middlesex, Civil
Engineer, for the Invention of " IMPROVED MACHINERY FOR MOULDING
BRICKS, BLOCKS, OR OTHER ANALOGOUS ARTICLES COMPOSED OF PLASTIC OR
OTHER SUBSTANCES."-A communication from abroad by Ernest
Couillard, of Paris, in the Republic of France.
PROVISIONAL SPECIFICATION left by the said William Edward
Newton at the Office of the Commissioners of Patents, with his
Petition, on the 6th August 1878.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer; do hereby declare
the nature of the said Invention for " IMPROVED MACHINERY FOR MOULDING
BRICKS, BLOOKS, OR OTHER ANALOGOUS ARTICLES COMPOSED OF PLASTIC OR OTHER
SUBSTANCES," to be as follows:—
The improved machinery for moulding bricks, blocks, or other
analogous articles possesses the following advantages, viz. :—
1st. Continuity of motion in the moulding operations, so that there is

page_text: no loss of time, and consequently there is a greater production than in
machines of a similar character or class.
2nd. Carrying on the moulding operation slowly and gradually, so
that the cooling of the substance in the moulds may be also gradual and
slow, and a better cohesion of the ingredients thereby obtained. These
advantages are obtained by a peculiar construction, arrangement, and
mode of operating the several parts of the apparatus, which consists
mainly of a rotating circular table provided with a number of radial
moulds, in which work plungers for compressing the plastic ingredients
when placed in the moulds. The circular table is rotated by means of a
pinion or wheel taking into a corresponding wheel on the under side or
edge of the rotating table. The under sides of the plungers rest upon
and travel on inclined planes below; one being fixed and the other
movable. The latter is connected to one end of a lever which bears
upon a set of springs, whereby a certain amount of elasticity is given
to it.
When the plungers travel along the moveable inclined plane (the
moulds having been previously charged with the plastic substance) the
latter will be forced up in the moulds and pressed against the under side
of a strong cast-iron cover fixed above the rotating table. When the
moulds escape from under the table the plungers travel up the fixed
inclined plane, and force the blocks or bricks out of the moulds. They
may then be removed for stacking and drying.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Newton in the Great Seal Patent ?
Office on the 6th February 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her;
Letters Patent, bearing date the Sixth day of August, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Edward Newton, Her special

page_text: licence that I, the said William Edward Newton, my executors, adminis-
trators, and assigns, or such others as I, the said William Edward
Newton, 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 Islands, and Isle of Man, an Invention for
"IMPROVED MACHINERY FOR MOULDING BRICKS, BLOCKS, OR OTHER ANALOGOUS
ARTICLES COMPOSED OF PLASTIC OR OTHER SUBSTANCEs," being a communication
to me from abroad by Ernest Couillard, of Paris, in the Republic of
France, upon the condition (amongst others) that I, the said William
Edward Newton, 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 William Edward Newton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing here-
unto annexed, and to the letters and figures marked thereon (that is to
say) :-
The improved machinery for moulding bricks, blocks, or other
analogous articles possesses the following advantages, viz'. :-
First. Continuity of motion in the moulding operation, so that there
is no loss of time, and consequently there is a greater production than in
other machines of a similar character or class.
Second. Carrying on the moulding operation slowly or gradually, and
cooling the substance in the moulds also gradually and slowly, so that a
better cohesion of the ingredients may be thereby obtained. These
advantages are attained by a peculiar construction, arrangement, and
mode of operating the several parts of the apparatus, which consists
mainly of a rotating circular table provided with a number of radial
moulds, in which work plungers for compressing the plastic ingredients
when placed in the moulds. The circular table is rotated by means of a
pinion or wheel taking into a corresponding wheel on the under side or

page_text: edge of the rotating table. The under sides of the plungers rest upon
and travel on inclined planes below, one being fixed and the other
moveable. The latter is connected to one end of a lever which bears
upon a set of springs, whereby a certain amount of elasticity is given
to it.
When the plungers travel along the moveable inclined plane (the
moulds having been previously charged with the plastic substance) the
latter will be forced up the moulds and pressed against the under side of
a strong cast-iron cover fixed above the rotating table. When the
moulds escape from under the table the plungers travel up the fixed
inclined plane, and force the blocks or bricks out of the moulds. They.
may then be removed for stacking and drying.

In the accompanying Drawing Fig. 1 represents a vertical section of
the apparatus taken through the line of the central axle; Fig. 2 is a
plan or top view of the machine.

The substances or ingredients to be moulded are supplied either by
hand or 'by means of a filling apparatus, which conveys them to the
moulds b, b, of the moveable or revolving table B. These moulds are
provided with moveable blocks or pistons which are not shewn in the
Drawing. The revolving table B is actuated by a pinion H, which gears
into a bevil toothed wheel or circular rack K, which may either be fixed,
as shewn in the Drawing, or placed below the revolving table, if pre-
ferred. The moveable mould blocks or pistons are carried round with
the revolving table, and slide along the inclined plane N, which is
moveable, and is connected with a lever O, provided with a series of flat
springs, which admit of the lever rising and falling at will. The springs
compensate for all the inequalities of filling the moulds, and admit of
the moveable mould blocks or pistons acting even when they come in
contact with incompressible substances which may get into the moulds.
These blocks or pistons on passing up the inclined planes lift up the
substance contained in the moulds b, and compress it by pushing or
forcing it against the cap piece or cover C, which is fixed and firmly
secured to the foundation plate A. The delivery of the brick from the
moulds is effected by the blocks or pistons passing over another inclined
plane M. The revolving mould table B rests upon washers or collars d, d,
and turns thereon.

page_text: By means of the movable inclined planes not only is an uniformity
of compression (which is a recognized necessity) ensured, but any chance
of accident arising from overfilling the moulds is avoided, and the proper
working of the apparatus is provided for.
I may here state that in all machines heretofore employed for making
artificial fuel the ingredients as they issue in a pasty state from the
mixer or pug mill are passed into an apparatus where the steam may be
disengaged, which, when the ingredients are suddenly compressed, would
otherwise prevent them from being properly moulded. In the improved
apparatus however all the heat necessary for moulding the blocks will
be retained in the pasty mass, and I thus am enabled to obtain a better
cohesion of the particles in consequence of the ingredients being hotter.
I would observe that I reserve to myself the right of applying this
improved moulding machine to the manufacture of bricks or blocks of
artificial fuel or other substances by using the ordinary revolving tables,
and adapting thereto the essential parts of the present Invention, which
I consider to be,—
First. Imparting to the revolving table a continuous rotary motion.
And, Second. The use of inclined planes, which are capable of yielding

First. Imparting to the revolving table a continuous rotary motion.
And, Second. The use of inclined planes, which are capable of yielding
when any undue pressure is put upon them.
In witness whereof, I, the said William Edward Newton, have
hereunto set my hand and seal, the Sixth day of February, in the
year of our Lord One thousand eight hundred and seventy-four.
