page_text: LETTERS PATENT to William Kemsley, of Borden, in the County of Kent, Brick-
maker, for the Invention of "IMPROVEMENTS IN MEANS FOR PROTECTING
BRICKS ON THE HACK OR DRYING GROUND.
Sealed the 15th August 1876, and dated the 23rd June 1876.
PROVISIONAL SPECIFICATION left by the said William Kemsley at the Office
of the Commissioners of Patents on the 23rd June 1876.

"IMPROVE-
MENTS IN MEANS FOR PROTECTING BRICKS ON THE HACK OR DRYING GROUND."
The Invention has for its object improvements in means for protecting bricks on
the hack or drying ground.
Heretofore according to one arrangement moveable covers either of wood or
thatched straw have been employed for protecting bricks on the hack or drying
ground; or according to another arrangement a fixed covering or roof has been
employed over each "hack," but according to such arrangements the coverings
simply conducted the rain water to the sides of each "hack" and did not protect
the sides of the bricks on the hack either from a driving rain or from the rain water
falling from the coverings, which in falling frequently splashes up against the bricks
and moistens them.
According to another arrangement the entire hack ground was covered in by a
weather-tight roof, which plan, although successful in protecting the bricks on the
hacks from rain, interfered with or delayed the drying of the bricks by preventing
the free evaporation and passing away of the moisture therefrom.
Now according to my Invention I not only protect the bricks from the rain but
provide for the free evaporation and passing away of moisture therefrom. For this
purpose I fix over each "hack
a permanent waterproof covering or roof extending
on each side a short distance beyond the bricks on the hack, and provided with
suitable gutters or channels to conduct the rain water falling thereon to either or
both ends of the hack, where it falls into suitable channels or drains, and is con-
ducted away from the ground. The spaces between these waterproof coverings or
roofs are covered in by open basketwork, preferably made with brushwood or
bushes interlaced with or laid on suitable horizontal supports; but other suitable
openwork may be employed. Thus any rain falling on to the brushwood or other
Price 6d1

page_text: openwork covering is prevented thereby from being driven against the bricks on
the hacks, and is caused to fall to the ground in perpendicular lines therefrom,
where it is received into suitable gutters, drains, or channels, and is conducted
away from the bricks, whilst the vapour or moisture rising from the bricks is
allowed free egrees through the brushwood or other openwork covering. The bricks
on the outer hacks are protected on the outer sides thereof by an extension of the
basket or other openwork covering at those parts combined with a board or guard
descending a short distance therefrom to protect the bricks against a driving
rain. The bricks on the ends of the hacks are protected from rain by extensions
of the waterproof and openwork coverings.

WILLIAM KEMSLEY, of Borden, in the County of Kent, Brickmaker.
MENTS IN MEANS FOR PROTECTING BRICKS ON THE HACK OR DRYING GROUND."
The Invention has for its object improvements in means for protecting bricks on
the hack or drying ground.
Heretofore according to one arrangement moveable covers either of wood or
thatched straw have been employed for protecting bricks on the hack or drying
ground; or according to another arrangement a fixed covering or roof has been
employed over cach "hack," but according to such arrangements the coverings
simply conducted the rain water to the sides of each "hack," and did not protect the
sides of the bricks on the hack either from a driving rain or from the rain water
falling from the coverings, which in falling frequently splashes up against the bricks
and moistens them.
According to another arrangement the entire hack ground was covered in by a
weather-tight roof, which plan, although successful in protecting the bricks on the
hacks from rain, interfered with or delayed the drying of the bricks by preventing
the free evaporation and passing away of the moisture therefrom.
Now according to my Invention I not only protect the bricks from the rain but
provide for the free evaporation and passing away of moisture therefrom. For this
purpose I fix over each "hack" a permanent waterproof covering or roof extending
on each side a short distance beyond the bricks on the hack, and provided with
suitable gutters or channels to conduct the rain water falling thereon to either or
both ends of the hack, where it falls into suitable channels or drains and is con-
ducted away from the ground. The spaces between these waterproof coverings or
roofs are covered in by open basketwork, preferably made with brushwood or
bushes interlaced with or laid on suitable horizontal supports; but other suitable
openwork may be employed. Thus any rain falling on to the brushwood or other
openwork covering is prevented thereby from being driven against the bricks on
the hacks, and is caused to fall to the ground in perpendicular lines therefrom,
where it is received into suitable gutters, drains, or channels, and is conducted
away from the bricks, whilst the vapour or moisture rising from the bricks is
allowed free egress through the brushwood or other openwork covering. The bricks
on the outer hacks are protected on the outer sides thereof by an extension of the
basket or other openwork covering at those parts combined with a board or guard
descending a short distance therefrom to protect the bricks against a driving rain.
The bricks on the ends of the hacks are protected from rain by extensions of the
waterproof and openwork coverings.
And in order that my said Invention may be more clearly understood and readily
carried into effect, I will proceed, aided by the accompanying Drawings, more fully
to describe the same.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal sectional elevation on the line 1, 1, of Figure 3.
Figure 2 is an end elevation, Figure 3 is a plan, and Figure 4 is a sectional plan
on the line 2, 2, of Figure 1, showing my Invention applied to a hack or drying
ground.
a are the hacks, which, according to my Invention, are covered by a fixed per-
manent waterproof or watertight covering or roof b extending on each side a short
distance beyond the bricks on the hack, and provided with suitable gutters or
channels, as shown, to conduct the rain water falling thereon to either or both ends
of the hack, where it falls into suitable channels or drains c and is conducted away
from the ground. These coverings or roofs bare carried by horizontal supports 61
supported on uprights b². The spaces 6 between these waterproof or watertight
coverings or roofs b are covered in by open basketwork, preferably made with
brushwood or bushes interlaced with or laid on the horizontal supports b¹; but in
cases where it is difficult to obtain this brushwood or, if preferred, a coarse woven
sackcloth or other fabric having spaces between the strands thereof or other suitable
openwork may be employed, and when employing such a description of fabric I
prefer to support the same by hooks or rings to wires or rods suitably arranged for
such purpose, whereby I am enabled readily to move the openwork covering aside
in fine weather to allow the more rapid passing away of the moisture. Thus any
rain falling on to the brushwood or other openwork covering is prevented thereby
from being driven against the bricks on the hacks, and is caused to fall to the
ground in perpendicular lines therefrom, as indicated by the dotted lines, where
it is received into suitable gutters, drains, or channels d, and is conducted away
from the bricks, whilst the vapour or moisture rising from the bricks is allowed free
egress through the brushwood or other openwork covering 6. The bricks on the
outer hacks are protected on the outer sides thereof by an extension 6 of the basket
or other openwork covering at those parts combined with a board or guard e
descending a short distance therefrom to protect the bricks against a driving rain;
or such openwork covering may be fixed in an angular position, as shown by the
dotted lines f, whereby the board or guard e may be dispensed with. The bricks on
the ends of the hacks are protected from rain by extensions of the waterproof and
openwork coverings, either in a horizontal direction or in an inclined direction, as
shown by the dotted lines g, as will be readily understood.
Having thus described the nature of my said Invention, and the mode in which
I carry the same into effect, I would have it understood that what I claim is, the
mode of protecting bricks on the back or drying ground by the employment of
permanent waterproof or watertight coverings or roofs provided with gutters or
channels combined with basket or other openwork coverings in manner substantially
as herein shown and described.
In witness whereof, I, the said William Kemsley, have hereunto set my hand
and seal, this Nineteenth day of December, in the year of our Lord One
thousand eight hundred and seventy-six.
