AN IMPROVED METHOD OR IMPROVED PROVISIONAL HODS OF CONSTRUCTING OR BUILDING HAY AND OTHER RICES
Year: 1856

page_text: LETTERS PATENT to William Church, of Birmingham, in the County of
Warwick, Engineer, and Henry Whiting Hamlyn, of Birmingham afore-
said, Corn Factor, for the Invention of "AN IMPROVED METHOD OR IMPROVED
PROVISIONAL SPECIFICATION left by the said William Church and
Henry Whiting Hamlyn at the Office of the Commissioners of Patents,
with their Petition, on the 18th August 1856.
We, WILLIAM CHURCH, of Birmingham, in the County of Warwick,
Engineer, and HENRY WHITING HAMLYN, of Birmingham aforesaid, Corn
Factor, do hereby declare the nature of the said Invention for "AN IMPROVED
METHOD OR IMPROVED METHODS OF CONSTRUCTING OR BUILDING HAY AND OTHER
RICES," to be as follows:-
Our Invention consists of constructing hay and other ricks with horizontal
and vertical shafts or flues in their interior, as herein-after explained. The
said shafts or flues having for their object the ventilation of the ricks, and
the prevention of the injurious effects which the want of ventilation frequently
gives rise to. We prefer to carry our Invention into effect in the following
manner-We construct a series of horizontal flues or shafts on the ground or
foundation on which a rick is to be built, the said flues converging to a centre,

page_text: and terminating in a vertical flue or shaft. About this system of flues we
build or construct the rick. The outer ends of the horizontal flues, and the
upper end of the vertical flue are open to the air, and a circulation of air takes
place from the horizontal flues up the vertical flue. The said flues may be
constructed of perforated sheet metal, or wire gauze, or other material
permeable to the air. Where the rick is very large, more than one vertical
flue may be employed, and two or more systems of horizontal flues may be
made to open into the vertical flue or flues.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Church and Henry Whiting Hamlyn in the Great
Seal Patent Office on the 10th February 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
СHURCH, of Birmingham, in the County of Warwick, Engineer, and HENRY
WHITING HAMLYN, of Birmingham aforesaid, Corn Factor, sond greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of August, in the year of our Lord One
thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
William Church and Henry Whiting Hamlyn, ITer special licence that we, the
said William Church and Henry Whiting Hamlyn, our executors, adminis-
trators, and assigns, or such others as we, the said William Church and Henry
Whiting Hamlyn, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "AN IMPROVED METHOD
OR IMPROVED METHODS OF CONSTRUCTING OR BUILDING HAY AND OTHER RICKS," upon
the condition (amongst others) that we, the said William Church and Henry
Whiting Hamlyn, our executors or administrators, by an instrument in writing
under our or their hands and seals, or under the hand and seal of one of us
or them, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Whiting Hamlyn, do hereby
declare the nature of the said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
Our Invention consists in constructing or building hay and other ricks with
borizontal and vertical shafts or flues in their interior, as herein-after explained
and illustrated in the accompanying Drawing.
The said shafts or flues have for their object the ventilation of the ricks, and
the prevention of overheating and other injurious effects which the want of
ventilation frequently gives rise to.
.
Figure 1 of the accompaning Drawing represents in elevation, and Figure 2
in transverse section, a hay rick constructed or built according to our
Invention; Figure 3 represents a plan of the foundation of the same. We
construct a series of horizontal flues or shafts marked a on the ground or
foundation on which the rick is to be built; the said shafts or flues converge
to the centre b, and terminate in the vertical flue or shaft c. About this
system of shafts or flues we construct or build the rick d. Where it is deemed
necessary, we insert horizontal flues at different levels in the rick, as represented
at e, e, Figures 1 and 2, the said flues entering into the central flue or shaft c.
Although we prefer the diagonal arrangement of the horizontal flues"
represented in Figure 3, yet we do not limit ourselves thereto, as the said
flies may run in directions parallel to the sides of the rick. Where the
rick is largo, we sometimes place more than one vertical flue in the rick;
a system of vertical flues for a large rick is indicated by the letters f, f, in
Figures 1 and 3.
In order to control the draught, we furnish the open ends of the horizontal
flues with traps or valves g. 9, one of which is shown on a larger scale in
Figure 4. By raising or depressing the damper or plate h, the circulation of
air through the said flues may be regulated. The open mouth of the flues
may be covered with perforated metal or wire gauze, to prevent the entrance
of vermin.
We prefer to make the horizontal and vertical flues of thin perforated sheet
metal, one of the said flues is represented in Figure 5, or the said flues may
be made of wire gauze, or any other suitable material, but we do not limit
ourselves thereto. After the building of the rick has been completed, tho
vertical flues may be withdrawn. We sometimes make the vertical flues by
taper poles, having haybands coiled around them. These we insert in the
rick during the building, the small end being placed downwards, and the poles
are withdrawn after the rick is complete.
By our inproved method of constructing or building hay and other ricks,
the grain or other agricultural produce, of which the said ricks are composed,

page_text: may be more effectually preserved than by the ordinary method of constructing
ricks.
Having now described the nature of our said Invention, and the manner o
carrying the same into effect, we wish it to be understood that we do not limit
ourselves to the precise details herein described and represented, as the same
may be varied without departing from the nature of our said Invention; but
we claim as our Invention the improved method or improved methods herein-
before described and illustrated in the accompanying Drawing, of constructing
or building hay and other ricks, that is to say, the introduction of horizontal
and vertical flues into hay and other ricks.
In witness whereof, I, the said Henry Whiting Hamlyn, have hereunto
set my hand and seal, this Ninth day of February, in the year of our
Lord One thousand eight hundred and fifty-seven.
Witness,
GEORGE SHAW.
