Figure 1, is a perspective view of the drier.
Figure 2, is a transverse section.
Figure 3 is a part longitudinal section, and
Figure 4 is a plan view with the upper portion of the drier removed.
Similar letters of reference indicate corresponding parts in all the figures of
the drawing.
In the accompanying drawing A, represents the outer side walls, which are
placed upon suitable foundations and are formed of a height to correspond sub-
stantially with the height of the drier. Upon the side walls A, are located suitable
rafters or other supports for the roof which roof may be constructed of any
suitable material, preferably of metal or other non-combustible material.
Below the roof d, and between the side walls A, are located any desired number
of tunnels B Figures 2 and 3-in the drawings six (6) are shown: but it will be
understood that a greater or less number may be employed, reference being had to
the capacity of the drier designed to be constructed, as it will be understood that
the principle of my invention can be carried out if but a single tunnel is con-
structed. The tops of the tunnel or tunnels B, are provided with the closed.
ceilings b, Figure 2, which ceilings are located a short distance below or under the
roof a, thereby forming a chamber or attic for the purpose hereinafter described.
For the purpose of better retaining the heat, the top or upper side of the
ceiling b, is covered with a layer of earth, which may be of any desired thickness,
reference being had to leaving between the upper side of the earth and the under
side of the roof a space or chamber C, to carry out the objects and purposes
hereinafter described. Each of the tunnels B, are provided with suitable floors,
upon which are placed suitable car tracks, such as c. Within the tunnels or
tunnels B, are located suitable steam pipes d, which pipes may be arranged along
the sides of the tunnel or tunnels, and at their bottoms, said pipes may be arranged
as illustrated in the drawing, or they may be differently arranged, inasmuch as
the purpose of the pipes can be carried out without any particular reference to
their location.

page_text: From the chamber or attic C, extend the air passages which air passages are
open at their upper ends and communicate with the chamber or attie C, said air
passages extending downward below the floor or floors of the tunnels and opening
into the tunnel through the floor or floors, as illustrated in Figure 2. The air
passages or flues, are located at intervals along the tunnel and may be any
desired distance apart. From the bottom of the tunnels B, lead the vapour
flues D, which vapour flues may be located substantially as shown in the drawing,
and are for the purpose of removing from the tunnel the vapour arising from the
damn brick during the time they are being dried. The vapour flues D, are each
provided with openings which openings are formed directly above each other, and
preferably in horizontal lines or rows, which openings are to be closed by means
of the dampers f, and g, which dampers are pivoted to the vapour flues D, or their
equivalents at their upper ends, and their bottom or lower ends. connected to the
slide bars and h', which slide bars are formed of a length to correspond sub-
stantiany with the length of the tunnels, or of such a length that all the dampers f,
or 4, may be connected to the proper slide bar.
For the purpose of operating the slide bars without entering the tunnels, they
are extended outward from one end of the tunnel and are provided with proper
handles. The object and purpose of providing two or more horizontal rows of
openings in the vapor flues D, is to provide a means for permitting the air
contained within the tunnel laden with the dampness and vapor arising from the
brick, to be drawn off at different heights of the tunnel, thereby providing a
means for better removing the vapor from the tunnel or tunnels. In use, during
the time the brick contained within the tunnel or tunnels are being dried, the
chamber or attic located above the tunnels becomes heated to a high degree, and
by my peculiar arrangement this surplus heat is conveyed from the chamber or
attic downward to the bottom of the tunnel or tunnels, and permitted to enter the
tunnel and be utilized in drying the brick.
It will be understood that when the dampers f, or g, are open or when all of
the dampers are open, that a draught will be produced through the vapor flues,
thereby removing the vapor laden air, and permitting the dry hot air to enter the
tunnel from the chamber or attic (C'.
By this peculiar arrangement, I am enabled to dry brick more rapidly, and at
the same time use less fuel than would otherwise be necessary, inasmuch as the
surplus heat contained in the chamber or attic is employed or used.
It will be understood that the vapor flues D Figures 1 to 4, are to be located at
intervals along the tunnel or tunnels, by which arrangement a more direct draught
is produced.
For the purpose of providing proper drainage, pits A, are provided, and are
located at the ends of the tunnels. In Figure 3, the steam pipes are not shown,
nor are they shown in all of the tunnels in Figure 2.
Having now particularly described and ascertained the nature of the invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondents, I declare that what I claim is: : -
1. The combination of a tunnel, steam pipes located therein, an air chamber
located above the tunnel and separated therefrom, air passages leading from the
separated air chamber downward and opening into the tunnel, substantially as and
for the purpose specified.
2. The combination of a tunnel or tunnels, an air chamber separated from the
tunnel or tunnels, air passages leading from the separated air chamber downward
and opening into the tunnels at points below the air chamber, vapor flues com-
municating with the tunnel or tunnels, and a series of dampers and openings
located above each other, substantially as and for the purpose specified.
3. The combination of a tunnel or tunnels, an air chamber located above the
tunnel or tunnels and separated therefrom, vapor flues communicating with

page_text: the tunnel or tunnels, a series of dampers and openings formed in and connected
to the vapour flues, steam pipes located within the tunnel or tunnels, and air
passages leading from the separated air chamber and opening into the tunnel or
tunnels below said air chamber, substantially as and for the purpose specified.
4. The combination of a tunnel or tunnels, vapor passages leading from the
tunnel or tunnels having openings located above each other and between the top
and bottom of the tunnel or tunnels, and dampers to close the openings,
substantially as and for the purpose specified.
5. The combination of a tunnel or tunnels, ceilings located over the tunnel or
tunnels and covered with a layer of earth, an air chamber located between the
earth and the roof, air passages leading from the openings or chamber above the
tunnels downward and opening into the tunnels below the ceiling or ceilings, and
vapor flues provided with dampers leading from the tunnels to the atmosphere,
substantially as and for the purpose specified.
