page_text: LETTERS PATENT to Daniel Richard Oaddick, of Middlesbrough-on-
Tees, in the County of York, Furnace Builder, for the Invention
of "IMPROVEMENTS IN THE CONSTRUCTION OF MACHINERY FOR the Manu-
FACTURE OF BRICKS, BLOCKS, TILES, AND OTHER SIMILAR ARTICLES FROM Slag
OR SCORIA."
Sealed the 21st March 1876, and dated the 6th October 1875.
.
PROVISIONAL SPECIFICATION left by the said Daniel Richard Caddick
at the Office of the Commissioners of Patents, with his Petition,
on the 6th October 1875.
I, DANIEL RICHARD CADDICK, of Middlesbrough-on-Tees, in the
County of York, Furnace Builder, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF MACHINERY FOR
THE MANUFACTURE OF BRICKS, BLOCKS, TILES, AND OTHER SIMILAR ARTICLES FROM
SLAG OR SCORIA," to bo as follows:-
This Invention consists in the construction of machinery for manu-
facturing bricks and other articles from slag or scoria, in a much more

page_text: simple, effectual, and economical manner than by the means hitherto
employed.
Upon the outer circumference of a circular table or wheel a number
of wedge-shaped mould guides are formed or placed, and in which mould
guides the moulds work. The smaller ends of the wedge-shapod guides
are nearest the centre or axis of the circular table or wheel, and the
bottoms thereof, which are made of iron, form the bottoms of the
moulds, and are kept cool by means of a jet of water playing thereon,
the bottoms of the broader ends of the wedge-shaped guides being
provided with an aperture for the brick or other article to pass through,
as herein-after mentioned. The moulds are formed in two parts, the two
ends being attached to or formed with one of the sides, the other side
being separate and apart therefrom. Both sides of the mould are suitably
bevelled or sloped, so that when they are placed in the narrow end of
the guides they are held tightly together.
The circular table or wheel, which may be constructed of T iron or
other suitable material, is mounted upon suitable wheels, so as to be
capable of revolving horizontally upon its axis.
The machine is placed in front of the slag hole, or in any other suitable
position, and the moulds, which are tightened into the narrow ends of
the guides, brought successively under the slag hole or tap, and when
one is filled the circular table or wheel is revolved until the next mould
is brought into position to be filled, and so on. When the slag in the
mould is sufficiently "set" to allow of its removal therefrom, the mould
is pushed or drawn by any suitable and convenient means from the
narrow to the broad end of the guide, thus loosening the moveable side
of the mould sufficiently to allow the brick or other article contained
therein to drop through the aperture in the bottom of the guide on
to a suitable carriage for removal to the annealing kilns or cooling
slicds.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Daniel Richard Caddick in the Great Seal Patent
Office on the 6th April 1876.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of October, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Daniel Richard Caddick, Her
special licence that I, the said Daniel Richard Caddick, my executors,
administrators, and assigns, or such others as I, the said Daniel Richard
Caddick, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 Inven-
tion for "IMPROVEMENTS IN THE CONSTRUCTION OF MACHINERY FOR THE MANU.
FACTURE OF BRICKS, BLOCKS, TILES, AND OTHER SIMILAR ARTICLES FROM SLAG OR
SCORIA," upon the condition (amongst others) that I, the said Daniel
Richard Caddick, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 Daniel Richard Caddick, 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 Drawings
hereunto annexed, and to the figures and letters marked thereon, that
is to say:-
My Invention consists in the construction of machinery for manu-
facturing bricks and other articles from slag or scoria in a more
simple, effectual, and economical manner than by the means hitherto
employed.
According to my Invention upon the outer circumference of a circular
table or wheel a number of wedge-shaped mould guides are formed
or placed, and in which the moulds work. The smaller ends of the
wedge-shaped guides are nearest the centre or axis of the circular tablo
or wheel, and the bottoms thereof, which are made of iron or other
suitable material, form the bottoms of the moulds, and may be kept cool

page_text: by means of a jet of water playing thereon. The bottoms of the broader
onds of the guides are left open or provided with an aperture for the
passage of the formed brick or other article, as herein-after mentioned.
The moulds are formed in two parts, and in such manner that when
placed in the narrow ends of the guides they are held tightly together.
The framework of the machine may be constructed of T iron or other
suitable material, and is mounted upon suitable wheels, so as to be
capable of revolving horizontally upon its axis.
The machine is placed in any suitable position, and the moulds, which
are tightened into the narrow ends of the guides, brought successively
under the slag hole or tap, and when one is filled the machine is
revolved until the next mould is brought into position to be filled, and
so on. When the slag in the mould is sufficiently "set" to allow of
its removal therefrom the mould is moved from the narrow to the broad
end of the guide, thus allowing the two portions thereof to separato:
sufficiently to release the brick or other article contained therein, and to
allow it to drop through the aperture in the bottom of the guide on to a
suitable carriage for removal to the annealing kilns or other desired
place.
I will now proceed to refer to the accompanying Drawings, from
which the nature of my said Invention will be more clearly understood.
Figures 1 and 2 shew respectively a sido elevation and plan of a wheel
or table constructed of T iron, as herein-before described.
Figures 3 and 4 are respectively a side elevation and plan of a
segment of a wheel, shewing the moulds fixed in the narrow end of the
guides.
A is the wheel; B, the outer circumference thereof, on which are
placed the guides and moulds; C, the moulds, which may be of any
desired section; D, the guides, the sides of the narrow ends of which
are shewn formed by stops of metal, but they may be a continuation of
the metal forming the sides of the broad ends thereof. E, E, are the
apertures or openings in the bottoms of the guides for the passage of the
brick or other article; and F, Figure 3, is the water jet for keeping the
bottoms of the guides cool.
Figures 5, 6, and 7, shew examples of moulds constructed according to
my said Invention. A and B are the two portions thereof, which separațe

page_text: when the mould is removed to the broad end of the guide; and O is a
lug or projection, with an eye formed therein to facilitate the removal of
the mould from the narrow to the broad end of the guides.
Having thus described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I would observe
in conclusion that I do not claim the circular wheel or table by itself,
but what I consider novel and original, and therefore claim as con-
stituting the Invention secured to me by the herein-before in part
recited Letters Patent are,-
Firstly. The construction and arrangement of machines for manu-
facturing bricks and other articles from slag or scoria, in the manner
herein-before set forth and described, or any mere modifications thereof.
And, Secondly. The employment of moulds of any desired section,
formed in two parts and working between guides, in machines for making
bricks or other articles from slag or scoria, in the manner and for the
purposes herein-before set forth and described.
In witness whereof, I, the said Daniel Richard Caddick, have
hereunto set my hand and seal, this Third day of April, in the
year of our Lord One thousand eight hundred and seventy-
six.
