Improvements in the Construction of Drying Rooms or Chambers,
especially Suitable for Treating Cement, Slurry, and the like.
I, CHARLES LANCELOT BOOTH, of No. 3, Gray's Inn Square, in the County of
London, Cement Manufacturer, do hereby declare the nature of this invention
to be as follows:-
The present invention has reference to improvements in the construction of
drying rooms or chambers, and is especially suitable for drying cement
slip or slurry, but is also applicable for drying sand, mud, paper,
fabrics, and in fact any other substance or article required to
be more or less dehydrated speedily and economically. The main object of it
is to provide a means whereby the substance or goods under treatment in any
part of the drying chamber can be with facility removed without entering
the chamber and without necessitating the prior removal of any other portion
of the substance or goods in order to gain access to the portion it is desired to
remove.
There are various constructions of drying floors, rooms and chambers at present
in use for the drying of cement material in the state of slurry or like substance
and for other drying or dehydration purposes, but this invention is designed
more particularly as an improvement upon the construction characterised
by the drying chamber consisting of an air-tight tunnel or cylinder through
which a current of hot air is sent either from a special furnace or from the
waste heat of combustion led from the calcining kilns or may be from the sub-
sequent burning kilns, or both; the air entering at one end and passing out
at the other up a chimney. Such drying chambers invariably have only the
two end openings or doors by which the tunnel can be entered, and the material
to be dried is spread on trays supported on trucks or trolleys which run on rails
laid throughout the tunnel or drying room.
From the above it follows that, as there are only the two end entrances and
the trucks all stand in alignment on the railway, should it be desired to extract
the contents of say a centrally situated truck, it is necessary to first run
those trucks out of the tunnel which are in front of the one it is desired to
empty or make the extraction from, which is the chief inconvenience my inven
tion is designed to overcome.
My invention consists in providing a drying chamber of the above type with
one or more lateral or side doors so that the contents at certain or any part or parts
of the chamber may be readily inspected or removed without disturbing the con-
tents at any other part or parts of the chamber; and, further, I dispense with the
railway and trucks entirely and substitute therefor one or more shelves which may
be either fixed or movable. The said lateral doors may be either plain or glazed
or provided with shuttered peep-holes for the inspection of the contents of the
chamber. With a chamber thus constructed, when it is desired to extract the
contents from, say, the middle of the tunnel, it is only necessary to shut-off

page_text: the damper which is admitting the hot air from the kiln or furnace as the case may
be and open the middle lateral door, when the extraction of the contents desired
may be made with the greatest facility by if slurry or the like-merely raking
it forward off the shelf into a receptacle placed in front to receive it.
There may be two or more of such drying tunnels or chambers superposed or
otherwise arranged and either contiguously or quite apart from one another and
only connected by conduits to convey the hot air or other drying agent.
I do not confine myself to the use of hot air as the drying medium; dry steam
or any other suitable agent may be employed, and likewise the source from which
it is obtained is immaterial to this invention.

Improvements in the Construction of Drying Rooms or Chambers,
especially Suitable for Treating Cement, Slurry, and the like.
I, CHARLES LANCELOT BOOTH, of No. 3, Gray's Inn Square, in the County. of
London, 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:-
The present invention has reference to improvements in the construction of
drying rooms or chambers, and is especially suitable for drying cement
slip or slurry, but is also applicable for drying sand, mud, paper,
fabrics, and in fact any other substance or article required to
be more or less dehydrated speedily and economically. The main object of it
is to provide a means whereby the substance of goods under treatment in any
part of the drying chamber can be with facility removed without entering
the chamber and without necessitating the prior removal of any other portion
of the substance or goods in order to gain access to the portion it is desired to
remove which may be distant from both ends of the chamber.
There are various constructions of drying floors, rooms and chambers at present
in use for the drying of cement material in the state of slurry or like substance
and for other drying or dehydration purposes, but this invention is designed
more particularly as an improvement upon that construction which is characterised
by the drying chamber consisting of an air-tight tunnel or cylinder through
which a current of hot air is sent either from a special furnace or from the
waste heat of combustion led from the calcining kilns or may be from the sub-
sequent burning kilns, or both; the air entering at one end and passing out
at the other up a chimney. Such drying chambers invariably have only the
two end openings or doors by which the tunnel can be entered, and the material
to be dried is spread on trays supported on trucks or trolleys which run on rails
laid throughout the tunnel or drying room.
From the above it follows that, as there are only the two end entrances and
the trucks all stand in alignment on the railway, should it be desired to extract
the contents of say a centrally situated truck, it is necessary to first run
those trucks out of the tunnel which are in front of the one it is desired to
empty or make the extraction from, which is the chief inconvenience my inven-
tion is designed to overcome.
Referring to the accompanying sheet of drawings which are to form part of this
specification and read therewith and wherein :-
Figure 1 is a longitudinal sectional elevation of the improved drying chamber.

page_text: Figure 2 is an elevation.
Figure 3 is a sectional plan.
My invention consists in providing a drying chamber A of the above type with
ne or more lateral or side doors B, so that the contents at certain or any part or
parts of the chamber may be readily inspected or removed without disturbing the
ontents at any other part or parts of the chamber; and, further, I dispense with
he railway and trucks entirely and substitute therefor one or more shelves C which
may be either fixed or movable. The said lateral doors B may be either plain or
glazed, or provided with shuttered peep-holes for the inspection of the contents of
the chamber.
With a chamber thus constructed, when it is desired to extract the contents from
say, the middle of the tunnel, it is only necessary to shut-off the damper which is
admitting the hot air from the kiln or furnace as the case may be, and open the
middle lateral door B, when the extraction of the contents desired may be made
with the greatest facility by if slurry or the like-merely raking it forward off
the shelf into a receptacle placed in front to receive it.
There may be two or more of such drying tunnels or chambers A superposed or
otherwise arranged and either contiguously or quite apart from one another and
only connected by conduits to convey the hot air or other drying agent.
I do not confine myself to the use of hot air as the drying medium; dry steam
or any other suitable agent may be employed, and likewise the source from which
it is obtained is immaterial to this invention.
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. In a drying floor room or chamber consisting of an air-tight tunnel or
cylinder through which a current of hot air is passed, one or more side doors with
or without peep-holes, substantially as and for the purpose described.
2. In a drying floor room or chamber consisting of an air-tight tunnel or
cylinder through which a current of hot air is passed, one or more side doors with
or without peep-holes, and shelves fixed or movable, arranged longitudinally
throughout the tunnel or cylinder, substantially as and for the purpose described.
3. The combination of two or more drying tunnels or cylinders having one or
more side doors and shelves, as described.
