Improvements in the Process of Treating or Preparing Clay having
Large Quantities of Stones in it for the Manufacture of Bricks,
Tiles and such like.
We, ROBERT ALLEN ROSSBOROUGH, Shale and Clay Specialist, and JAMES PHILIP
PILE, Contractor, both of The Marlborough Brick Works, Blackhorse Lane,
Dublin, Ireland, do hereby declare the nature of this invention to be as follows:-
-
This invention has reference to improvements in the process of treating or
preparing clay of a stoney character, for the manufacture of bricks, tiles, and
such like, whereby a greater saving in time and labour is effected than by any
process hitherto in use so far as we are aware.
In carrying out our invention we first prepare a cylindrical chamber of suitable
material and of suitable dimensions in the interior of which we arrange a
central longitudinal shaft provided with radial blades or propellers of suitable
length and strength according to the class of work to be performed.
This chamber we call for convenience a "drying chamber."
We next prepare a second cylindrical chamber similarly equipped to that
just described with the exception that the blades or propellers partake more of
the character of "beaters."
This chamber we designate a "beating chamber." We then proceed to
arrange each chamber in suitable framework, or masonry in a manner whereby
it will be surrounded by suitable openings or flues for the purpose of enabling
heat to be applied to the outer surface and also carried longitudinally through
the interior.
Between both chambers a communication is established by means of chutes,
conveyors, elavators, or otherwise according to their position in relation to each
other.
Finally we arrange at the terminal end of the beating chamber a suitable
sifting screen or series of screens composed of one or more meshes according
to requirements, to which an oscillating or revolving motion is imparted by
suitable gear actuated by steam or other motive power.
As thus constructed and arranged the action of our invention is briefly as
follows:-
Rotary motion is imparted to the central propeller shaft in each of the
chambers by suitable gear actuated by steam or other motive power;-the motion
in the beating chamber being arranged at a considerably higher speed than that
in the drying chamber for the purpose presently described.
The clay to be prepared is taken direct from the pit (stones and all) and is
introduced through a suitable grating at the starting end of the drying chamber
through which it is conveyed by the rotating blades or propellers (or by other
means, such as an endless chain having blades or scoops and working on pillars
from each end of the cylinder or by a revolving cylinder with a spiral ring
running along the inside of shell) to the terminal end being operated upon and

chamber and passing through its interior as above described.

consider-
From the drying chamber the clay is conveyed to the beating chamber where
it is subjected to the action of the rotating beaters which rotate at
able speed-approximately 240 revolutions per minute--whereby the material is
completely disintegrated and the stones loosened from the clay which is then
discharged through a hopper or otherwise on to the sifting screen or screens
or through which it is passed and the stones effectually separated and
removed from the fine material which latter being now conveyed through the
damping pan or mixer is ready for the brick machine.
over
It must be understood that we may use two or more of each of the chambers
as herein described according to requirements, and that the same may be arranged
in any suitable position-either vertically, diagonally or horizontally-prefer-
ably horizontally.
Further they may be arranged either end to end, or in the same horizontal or
vertical plane, such arrangement being obviously subject to space available,
and other local circumstances.
We would also have it understood that in carrying out our invention the dry-
ing chamber herein described may be dispensed with and the clay conveyed
direct to the beating chamber from any well known or approved drying source.
In other words we desire to have it clearly understood that the essential feature
of our invention is the use and application of a chamber wherein the clay is
subject to a disintegration process whereby the stones are effectually loosened
and separated from the fine material in a novel and expeditious manner.

ROBERT ALLEN ROSSBOROUGH, Shale and Clay Specialist, and JAMES PHILIP
PILE, Contractor, both of The Marlborough Brick Works, Blackhorse Lane,
Dublin, Ireland, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement: —
This invention has reference to improvements in the process of treating or
preparing clay of a stoney character, for the manufacture of bricks, tiles and
such like, whereby a greater saving in time and labour is effected than by any
process hitherto in use so far as we are aware.
In carrying out our invention we first prepare a cylindrical chamber A of
suitable material and suitable dimensions, in the interior of which we arrange
a central longitudinal shaft B provided with radial blades or propellers of suit-
able length and strength according to the class of work to be performed.
This chamber

of beaters."

This chamber we designate a "beating chamber." We then proceed to

page_text: arrange each chamber in suitable framework, or masonry in a manner whereby
it will be surrounded by suitable openings or flues for the purpose of enabling
heat, if necessary, to be applied to the outer surface, and also carried longitudinally
through the interior.
Between both chambers a communication is established by means of chutes,
conveyors, elevators, or otherwise according to their position in relation to each
other.
Finally we arrange at the terminal end of the beating chamber a suitable
sifting screen or series of screens composed of one or more meshes according
to requirements, to which an oscillating or revolving motion is imparted by
suitable gear actuated by steam or other motive power.
As thus constructed and arranged the action of our invention is briefly as
follows:-
Rotary motion is imparted to the central propeller shaft in each of the
chambers by suitable gear actuated by steam or other motive power:--the motion
in the beating chamber being arranged at a considerably higher speed than that
in the drying chamber for the purpose presently described.
The clay to be prepared is taken from the pit (stones and all) and is
introduced through a suitable grating at the starting end of the drying chamber
through which it is conveyed by the rotating blades or propellers (or by other
means, such as and endless chain having blades or scoops and working on pillars
from each end of the cylinder or by a revolving cylinder with a spiral ring
running along the inside of shell) to the terminal end being operated upon and
dried to a certain extent while in transit, by the heat circulating round the
chamber and passing through its interior as above described.
From the drying chamber the clay is conveyed to the beating chamber where
it is subjected to the action of the rotating beaters which rotate at a consider-
able speed approximately 240 revolutions per minute-whereby the material is
completely disentegrated and the stones loosened from the clay which is then
discharged through a hopper or otherwise on to the sifting screen or screens
over or through which it is passed and the stones effectually separated and
removed from the fine material which latter being now conveyed through the
damping pan or mixer is ready for the brick machine.
It must be understood that we may use two or more of each of the chambers
as herein described according to requirements, and that the same may be arranged
in any suitable position-either vertically, diagonally, or horizontally--prefer-
ably horizontally.
Further they may be arranged either end to end, or in the same horizontal or
vertical plane, such arrangement being obviously subject to the space available
and other local circumstances.
We would also have it understood that in carrying out our invention the dry-
ing chamber herein described may be dispensed with and the clay conveyed
direct to the beating chamber from any well known or approved drying source.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed we declare that what
we claim is :-
The use and application of a chamber wherein the clay is subject to a dis-
entegrating process whereby the stones are effectually loosened and separated
from the fine material in a novel and expeditious manner.
