I EDWARD ORMEROD, specialist in concreto of 11 Victoria Road, Battersea Park
in the County of Surrey, do hereby declare the nature of my Invention for
IMPROVEMENTS IN APPARATUS & MODE FOR THE PRODUCTION OF PAVING SLABS,
BLOCKS, SINKS, MANHOLES, ROOFING TILES AND OTHER SIMILAR ARTICLES IN
CONCRETE OR TERRA COTTA AND OTHER SIMILAR MATERIALS, to be as follows:-
The principal object in this improved apparatus is to obviate the use and'cost of
the large number of costly moulds and keeping the same in repair and also to
avoid the necessity of having a large space under cover while the articles are
maturing.
My apparatus consist, firstly of a colapsable mould from 3 inches to 6 inches
deep or as deep as may be required and of such superficial area as necessary it has
vertical binges at 3 corners and is fastened together at the forth with hasps.
One side of the mould or moulds is fixed upon a table to keep it in position
underneath the die, which I now describe namely: This die is of the same size as
the mould above described, having a flange at the top which regulates the thickness
and density of the article being made. .I place my concrete, clay or other materials
in the mould and by use of hydraulic steam or other mechanical power I deem
most useful I force the die home into the mould thus rendering the article very
compact and dense I then by means of the claps or hasps mentioned I open the
inould and by means of a loose bottom in the mould I at once remove the com-
pressed article just made; this is done by the loose bottom having a projecting hook
to which I'attach a snatch or crook fixed to a chain or rope and by means of a
windlass or other such means I am enabled to at once. to withdraw the moulded*
article out of the 'mould' and transfer it along a table of the same level as mould
table and land it on to a table with swivel or on to a handbarrow fixed level with
the table and at once carry it away to set or dry as may be required.

I, EDWARD ORMEROD, Specialist in Concrete, of 11 Victoria Road, Battersea
Park, in the County of Surrey, do hereby déclare the nature of my Invention for
IMPROVEMENTS IN APPARATUS AND MODE FOR THE PRODUCTION OF PAVING
SLABS, BLOCKS, SINKS, MANHOLES, ROOFING TILES, AND OTHER SIMILAR ARTICLES
IN CONCRETE OR TERRA COTTA AND OTHER SIMILAR MATERIALS, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
The object of my Invention is to provide a new and improved mould for making
artificial stone, slabs, flags, tiles, coping, sinks, and other building stones in Concrete
and Terra Cotta and for different purposes.
My Invention consists in construction and combinations of parts and details as
will be fully described and set forth hereinafter.
Reference is to be had to the accompanying drawings forming part of this
specification in which similar letters of reference indicate corresponding parts in all
figures.
Fig. 1. is a plan view of the mould closed.
Fig. 2 is a plan view of the mould open.
Fig. 3 is a side view of the same.
Fig. 4 is a cross-sectional elevation of the same on the line X X Fig. 1. the
mould being filled.
Fig. 5. is a like view with the cover or die pressed down.
Fig. 6. is a cross-sectional view of the same, showing the manner of removing
the slabs or other stones.
The Mould is formed of the four Bars A. B. C. D. hinged together, the free ends
of the bars A and B being adapted to abut.
On the outer surface of the bar D, a bar E, is secured, which projects behind the
same, and has a notch F, in the upper edge of the projecting part.
A latch G is pivoted on the outer surface of the bar A and is adapted to be
passed into the notch F.
A bottom board H filling in the frame formed of the above bars, is provided with
a chain K which can be fastened.
The cover or die L which is of sufficient size to cover the entire top of the mould
has a downward projecting part M on the under side which part M fits into the
top of the mould or frame. The Mould can be made of Wood or Metal.
The operation is as follows:-
The Mould is closed around the edges of the bottom board H and locked by
means of the latch G, and then the Concrete or other composition N is filled into
the mould up to the top edge of the same, and the cover or die D is placed on the
concrete as shown in Fig. 4. and the mould is then placed under an Hydraulic Press

page_text: or other pressure, and the cover pressed down, whereby the projection M is forced
into the upper part of the mould, and thus the Concrete or other composition is
compressed.
The cover or die is then removed and the mould opened and the slab O formed
on the board H is drawn out by drawing out the board. A fresh bottom board is
then placed in the mould, and the operation repeated. The mould can also be used
without the die.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1. A mould formed of four bars hinged together, and one end bar having a
notched bar projecting behind the end, and an outside bar having a pivoted latch,
substantially as herein shown and described.
2. The combination A. B. C. D. hinged together, and of the bar E secured to the
bar D, and having a notch in its projecting end, and the latch G pivoted to the
bar A, and of the bottom board H filling in the frame formed by the bars A. B.
C. D. The cover or Die having the downward projecting part M. substantially as
herein shown and described.
