Year: 1874

page_text: LETTERS PATENT to Joseph Moore, of Darlington, in the County of
Durham, Engineer, for the Invention of "IMPROVEMENTS IN THE CON-
STRUCTION OF MACHINERY FOR MANUFACTURING BRICKS, TILES, SLABS, AND
BLOCKS FOR BUILDING AND OTHER PURPOSES."
Sealed the 23rd October 1874, and dated the 29th April 1874.
PROVISIONAL SPECIFICATION left by the said Joseph Moore at the
Office of the Commissioners of Patents, with his Petition, on the
29th April 1874.
I, JOSEPH MOORE, of Darlington, in the County of Durham, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF MACHINERY FOR MANUFACTURING BRICKS, TILES, SLABS,
AND BLOCKS FOR BUILDING AND OTHER PURPOSES," to be as follows:-
This Invention consists in the construction of machinery for manu-
facturing bricks, tiles, and slabs, or other similar articles, from molten
slag or scoria, by running the same into moulds and subjecting it to
suitable pressure. The sides of the moulds into which the molten slag

page_text: is run or poured are formed of cast or wrought iron or other suitable
metal, and are separate and apart from the bottom plate, and capable of
being raised therefrom by means of levers, eccentrics, or other suitable
appliances. The bottom plate and sides are made hollow, and are
respectively provided with suitable inlet and outlet pipes connected with
a tank or tanks for the supply of water thereto for the purpose of keeping
the moulds at the necessary temperature.
When it is desired to form a brick or other article the sides of the
mould are placed upon the bottom plate, and the molten slag or scoria
run into the mould thus formed; and when a sufficient quantity of slag
is contained therein, a hollow pressure block having a face corresponding
with the face desired to be given to the article in course of manufacture,
and supplied with water in a similar manner to the sides and bottom
plate of the mould, is, by means of levers, eccentrics, or other suitable
mechanical contrivances, brought to bear upon the exposed surface of
the molten slag in the mould.
When sufficient pressure has been exerted upon the slag, and the
brick or other article formed and partially cooled, the sides of the
mould, together with the pressure block are raised, leaving the brick or
other article on the bottom plate ready for removal to the stack or
annealing oven, as may be desired.
It will be readily understood that the water in the mould and pressure
block can be kept at any desired temperature for the prevention of the
expansion and contraction of the same, and for facilitating the cooling
of the article contained therein, and that its supply can be regulated by
means of suitable valves and cocks. Two or more moulds and pressure
blocks constructed as above described can, if desired, be combined
together and worked from the same set of levers, eccentrics, or other
suitable appliances, as will be well understood by persons conversant
with such matters.

filed by the said Joseph Moore in the Great Seal Patent Office on
the 29th October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
MOORE, of Darlington, in the County of Durham, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of April, in the year of our Lord
One thousand eight hundred and seventy-four, in the thirty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Joseph Moore, Her special licence, that I, the said
Joseph Moore, my executors, administrators, and assigns, or such others
as I, the said Joseph Moore, 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 "IMPROVEMENTS IN THE CONSTRUCTION OF MACHINERY
FOR MANUFACTURING BRICKS, TILES, SLABS, AND BLOCKS FOR BUILDING AND OTHER
PURPOSES," upon the condition (amongst others) that I, the said Joseph
Moore, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and scals, 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 Joseph Moore, 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, reference being had to the accompanying Drawings
and to the letters and figures marked thereon, that is to say :-
My said Invention consists in the construction of machinery for manu-
facturing bricks, tiles, and slabs, or other similar articles, from molten
slag or scoria, by running the same into moulds and subjecting it to
suitable pressure. According to this Invention the sides of the moulds
into which the molten slag is run or poured are formed of cast or

page_text: wrought iron or other suitable metal, and are separate and apart from
the bottom plate, and capable of being raised therefrom by means of
levers, eccentrics, or other suitable appliances, the whole being mounted
in suitable framework. The bottom plate and sides are made hollow,
and are respectively provided with suitable inlet and outlet pipes con-
nected with a tank or tanks for the supply of water thereto for the
purpose of keeping the moulds at the necessary temperature.
When it is desired to form a brick or other article the sides of the
mould are placed upon the bottom plate, and the molten slag or scoria
run into the mould thus formed. A sufficient quantity of slag having
been placed in the mould, a hollow pressure block having a face corre-
sponding with the face desired to be given to the article in course of
manufacture, and being supplied with water in a similar manner to the
sides and bottom plate of the mould, is, by means of levers, eccentrics,
or other suitable mechanical contrivances, brought to bear upon the
exposed surface of the molten slag in the mould.
When sufficient pressure has been exerted upon the slag, and the
brick or other article formed and partially cooled, the sides of the mould,
together with the pressure block are raised, leaving the brick or other
article on the bottom plate ready for removal to the stack or annealing
oven, as may be desired.
For the purpose of producing perforated bricks a number of hollow
pins or perforators may be attached to or formed on the pressure block
and connected with the interior of the same, so that the water contained
therein may enter into the pins or perforators for the purpose of keeping
them cool. If preferred instead of the brick or other article receiving
the pattern of its face from the pressure block, as herein-before men-
tioned the face of the bottom plate of the mould may be so formed as
to correspond with the face required to be given to the brick or other
article in course of manufacture, and the hollow pins or perforators.may
be attached to or formed on the bottom plate in a similar manner.
It will be readily understood that the water contained in the different
parts of the mould and in the pressure block can be kept at any desired
temperature for the prevention of the expansion and contraction of the
same, and for facilitating the cooling of the article contained therein,
and that its supply can be regulated by means of suitable valves and
cocks. Two or more moulds and pressure blocks constructed as above

page_text: described can if desired be combined together in the same framework
and worked from the same set of levers, eccentrics, or other appliances,
as will be well understood by persons conversant with such matters.
I will now proceed to refer to the accompanying Drawings, from
which the nature of my said Invention will be more clearly understood.
Figure 1 is a front elevation of a machine constructed as above
described, and in which the sides of the mould and the pressure block
are worked by levers; Figure 2 being an end view, and Figure 3 a plan
of the same. The same letters of reference indicate similar parts in the
several Figures.
A is the framework of the machine; B, the hollow bottom plate with
the water contained therein; C, the hollow sides of the mould, which are
raised by the rod c, worked by the lever c'; D, is the hollow pressure
block which is raised and lowered by the rod d, worked by the
lever d¹. The inlet and outlet pipes are shewn respectively at E and F,
Figure 1.
Having thus described and ascertained the nature of my said Inven-
tion and the manner in which the same is to be performed, I would
observe in conclusion that what I consider novel and original, and
therefore claim as constituting the Invention secured to me by the said
herein-before in part recited Letters Patent is, the construction of
machinery for the manufacture of bricks, tiles, slabs, and blocks from
slag or scoria, substantially as and for the purposes herein-before set
forth and described, or any mere modifications thereof.
In witness whereof, I, the said Joseph Moore, have hereunto set
my hand and seal, this Twenty-third day of October, in the
year of our Lord One thousand eight hundred and seventy-
four
