Complete Specification Accepted, 14th Sept., 1888
I, GEORGE MOFFATT RHYS LAYTON, of Arlesey, in the County of Bedford, Cement
Manufacturer, do hereby declare the nature of this invention to be as follows:-
According to my invention I allow the red hot cement or "clinker" as it falls or is
drawn from the furnace to pass into small trolleys or conveyers which are afterwards
pushed or drawn along a chamber or series of chambers with doors or dampers at
either end which can be closed for confining and concentrating the heat produced from
the hot cement or clinker and opened to admit or draw out the trolleys or conveyers
containing it.
The chambers are sufficiently wide to allow for the passage of the trolleys or other
conveyers through their whole length and are covered with iron plates or fire tiles
forming a floor upon which the cement material or slurry is pumped or laid for the
purpose of drying and removed as soon as dried.
The chambers are so arranged that the hot cement may be continually passed
through them or the trolleys or conveyers may remain stationary until the heat is
exhausted.
By passing the hot cement through these chambers in the manner described a con-
tinuous supply of dry material ready for burning can be obtained without any
expenditure of additional fuel.

page_text: I GEORGE MOFFATT RHYS LAYTON of Arlesey in the County of Bedford Cement
Manufacturer 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 :-
According to my invention I allow the red hot cement or "clinker" as it falls or is
drawn from the furnace to pass into small trolleys or conveyors which are afterwards
pushed or drawn along a chamber or series of chambers with doors or dampers at either
end which can be closed for confining and concentrating the heat produced from the hot
cement or clinker and opened to admit or draw out the trolleys or conveyors
containing it.
The Chambers are sufficiently wide to allow for the passage of the trolleys or other
conveyors through their whole length and are covered with iron plates or fire tiles
forming a floor upon which the cement material or slurry is pumped or laid for the
purpose of drying and removed as soon as dried.
The Chambers are so arranged that the hot cement may be continually passed
through them or the trolleys or conveyors may remain stationary until the heat is
exhausted.
By passing the hot cement through these chambers in the manner described a con-
tinuous supply of dry material ready for burning can be obtained without any
expenditure of additional fuel.
The waste gases from the kiln or furnace may be passed through a flue or flues
adjoining the Chambers.
Figure 1 is a plan shewing the arrangement I prefer in carrying out my invention.
Figure 2 is a vertical section shewing the position of the trolleys in the chambers
and of the iron plates above them forming the drying floors.
Figure 3 is an end elevation shewing the arrangement of the dampers at each end
of the Chambers.
Figure 4 shews the gradient of the tramway in the Chambers A and B respectively,
the decline towards the points of egress being sufficient to enable the trolleys to be
easily pushed along or drawn out of the Chambers.
A B are tunnels or chambers through which passes a narrow gauge tramway C. C.
The roof of each Chamber is formed by iron plates upon which the wet slurry is
pumped or laid.
At the commencement of the drying process the damper G is closed and the damper E
is open A trolley filled with hot cement clinker from the furnace is pushed on to the
turn table D by which it is moved in the direction of the Chamber A-The trolley is
then pushed into this Chamber and runs or is drawn towards the further end of it
when the Damper E is immediately lowered there being an interval of time pro-
portionate to the out put of the furnace before a second trolley containing cement
clinker is passed into the chamber in a similar manner-After the admission of each

page_text: trolley the damper E is closed and this is continued until the Chamber is filled with
trolleys containing the hot cement clinker-The damper G is then raised and the first
trolley is drawn out when this damper is imediately lowered and the trolley passed by
the turn tables H. H. into the second Chamber B where the same operation is con-
ducted as in Chamber A the clinker in the trolleys as they leave the second Chamber B
being sufficiently cool for removal to the grinding house and the turntable I being
provided for moving them in any direction required.
The whole operation is now continuous and the dampers being always immediately
lowered after the admission or withdrawing of each trolley a very high temperature is
soon obtained in the Chambers the heat ascending and rapidly drying the slurry which
is removed and renewed from time to time.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
"
1. Employing the hot cement or "clinker for drying the "slurry" or cement
material substantially as described.
2. Carrying the hot cement or "clinker" by trolleys or conveyors through a chamber
or series of chambers the top of which forms the floor for drying the "slurry" or
cement material substantially as described.
3. The apparatus substantially as described and shewn in the drawings.
