For the better placing of Sheets of Metal or other Sheets as a Covering
on Hay, Corn, Straw, or other Stacks or Ricks.
I, PETER ROTHWELL JACKSON, of Blackbrooke, in the County of Monmouth,
Gentleman, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved method of covering hay, corn and other
stacks or ricks, by means of sheets of metal or the like.
The use of sheets of galvanized corrugated metal or the like for covering stacks
presents obvious advantages over the usual method of thatching, but as commonly
applied various drawbacks are known to exist, particularly owing to the want of
efficient ventilation between the top of the stack and the impermeable cover..
Owing to this want of ventilation, moisture arising from the stack is liable to
condense on the under side of the sheets and may cause mildew at the top of
the stack and otherwise injure the quality of the materials in the stack.
My invention consists essentially in securing the said sheets by means of hooks,
rings, or the like to one or more bars supported in the top of the stack at a distance
of five or six feet above it. The top of the stack may be made practically flat,
the height of the supporting bars giving the requisite pitch to the covering sheets.
On these bars the sheets can be secured or detached as circumstances may require:
The exact form of construction may vary somewhat according to the nature of the
materials and the size of the stack to which the sheets are applied.
For the better placing of Sheets of Metal or other Sheets as a Covering
on Hay, Corn, Straw, or other Stacks or Ricks.
I, PETER ROTHWELL JACKSON, of Blackbrooke, in the County of Monmouth,
Gentleman, 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:-

Owing to this want of ventilation, moisture arising from the stack is liable to
condense on the under side of the sheets and may cause mildew at the top of
the stack and otherwise injure the quality of the materials in the stack.
Reterring to the accompanying drawing in which I have represented diagram-
matically a section of a hay rick covered with sheets according to my invention.
A represents the rick, B one of the central supporting bars, C the corrugated
iron sheets, E flat planks or strips of wood laid longitudinally along the top of
the stack close to the eaves in order to keep the sheets at a uniform level, and
afford them a firm support without allowing them to come into contact with the
hay in the rick.
The lower ends of the sheets are provided with cords, chains or wires F suitably
attached thereto and fastened to the heads of pins G driven into the sides of the
stack preferably at a distance of from fifteen to eighteen inches below the top of
the rick. The central supporting bars B are of such a height and strength that
they will support the upper ends of the sheets in the manner shewn, so as to afford
central ventilation. They are preferably connected together by a wooden or
metallic ridge piece and when the moisture generated by the heating of the
stack has escaped, it is advisable to cover the said ridge pieces by a metal, canvas
or other ridging along the whole length of the rick, which ridging may be con-
veniently fastened by means of a cord to the rings or chains which connect the
sheets with the bars.
The covering sheets are preferably the ordinary roofing sheets of galvanized
corrugated iron and these are arranged in the well known manner so as to have
sufficient overlap to prevent leakage between the sheets.
It is obvious that modifications of detail may be introduced, thus for instance,
the lateral supporting strips may be otherwise arranged or a single connected
central ridge frame may be substituted for the separate pins B, but such modifi-
cations of detail would fall within the scope of my invention.
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. The improved impermeable detachable and ventilated covering for ricks and
the like consisting essentially of a central support or supports attached to the
apex of the rick, overlapping covering sheets connected to said central support,
longitudinal supporting pieces maintaining the said covering sheets out of contact
with the rick and pins or stays securing the lower ends of said covering sheets
substantially as described.
2. In combination, the central supporting pins (B) galvanized iron covering
sheets (C), longitudinal supports (E), and retaining pins (G) constructed and
operating substantially as described with reference to the accompanying drawing.
