Improvements in Galvanized Iron Roofing for Hay and other
Stacks and in Means for Securing the same.
I, SAMUEL MULLETT WILMOT, of Grove Cottage, Cumberland Road, in the city and
county of Bristol, manager of galvanized iron works, do hereby declare the nature of
this invention to be as follows:-
According to this invention, which relates to metallic corrugated roofing for stacks
of hay and other produce, a free space for ventilation is provided by the adoption of a
semi-circular or arched ridge piece which is placed over the ridge and extends from
one end of the stack to the other. This ridge piece, which is open at the ends, is
holted at intervals to frames which, at the top, correspond in curvature to the ridge
piece and which extend downwards in the form of legs which are made to penetrate
the produce of which the stack is composed. Cross or fie bars, adjusted to the desired
height, are fitted to the frames and extend from one leg thereof to the other. By
these cross or tie bars the ridge piece is kept at the proper height, as the bars bear
upon the ridge or apex of the stack and act as stops to the further descent of the ridge
piece. From the base of the curved ridge piece extend wings designed to rest upon
the upper surface of the stack at each side of the ridge,
At their lower ends the said wings are bent or turned inwards and upwards, and to
the inside bend thus formed are hung the roofing plates or sheets which are provided
with suitable clips for the attachment.
Pins or spikes, passed at proper intervals through holes in the sheets, are driven
into the material of which the stack is composed. Towards the point of each pin or
spike is a diamond shaped tongue pivotted to the body of the pin which is recessed to
receive it. This tongue is so arranged on its pivot that no obstruction is thereby
offered to the insertion of the pin or spike, but any tendency to withdraw the pin after
insertion in the stack causes the tongue to assume a position crosswise on the pin and
constitute a means of anchorage therefor.

1; SAMUEL MULLETT WILMOT, of 6, Horatio Terrace, Cumberland Road, in the city
and county of Bristol, manager of galvanized iron works, 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 improved galvanized iron roofing for stacks in which this invention partly con-
sists is composed of sheets of corrugated galvanized iron linked to a hood or ridge
piece of plain sheet iron designed to be placed over the ridge or apex of the stack and
parallel therewith. The hood or ridge piece is open at the ends, and by its use a space
for free ventilation is afforded. It is furnished at each side with wings to which the
sheets covering other parts of the top of the stack are linked, hooked or otherwise
attached. Under one arrangement, the hood is bolted at intervals to frames which, at
the top, correspond in curvature with that of the hood and which extend downwards
in the form of legs or spikes which are designed to penetrate the hay or other produce
of which the stack is composed. Cross bars or ties, adjusted to a desired height, are
fitted to the frames and extend from one leg thereof to the other. These bars or ties.
maintain the hood or ridge piece at the position on the stack necessary for efficient
ventilation.
Under a modification, the spiked frames above mentioned are dispensed with and
stays are placed across the lower part of the curved hood. These stays rest on the top
of the stack and serve to maintain the hood at the desired height in the same manner
as the cross bars referred to in the arrangement first above described. The hood or
ridge-piece may be made in one or more lengths.
The roofing is secured upon the stack by pins or pegs passed through holes made
for their reception in the metal sheets and driven into the substance of the stack.
A convenient form of pin or peg for this purpose consists of a rounded and pointed
spike furnished towards the lower end with a diamond-shaped tongue or wedge
pivotted to the spike which is recessed to receive it. The tongue or wedge is so
arranged on its pivot that no additional material obstruction is thereby offered to
the insertion of the spike, but on being subjected to an upward or outward strain
tending to withdraw it the tongue or wedge assumes a position crosswise on
the spike and resists withdrawal.
At the ends or gables of the stack there are preferably placed tie rods which further
assist to keep the roofing in place on the stack.
Referring to the accompanying sheets of illustrative drawings, Fig. 1, represents an
end view of a portion of a galvanized iron stack roof constructed in accordance with
one arrangement comprised in this invention.
Fig. 2 représents a part plan and
end view thereof.
The hood a, which may be made in one or more lengths, is, under this arrangement,
bolted to frames placed at intervals along it. The frames & correspond at the top in
curvature with the hood. They are continued downwards in the form of spikes
which penetrate the hay or other produce of which the stack is composed. By the
cross bars or ties the hood is maintained above the apex of the stack upon which
the bars or ties rest. A space for free ventilation is thus provided in the hood which
C
is open at the ends.

page_text: The lower ends of the wings a¹ of the hood are turned inwards and upwards to form
hooks and to these hooks or bends are hung the corrugated galvanized iron sheets d
constituting the continuation of the roofing to the upper end of which are secured clips
d' by which the attachment is made. A part of these sheets is represented at Figs. 1
and 2, of the appended drawings. The roofing plates may be otherwise secured
to the wings a of the hood.
Under a modification, the spiked frames are dispensed with and the hood is
stayed at intervals by flat or rounded stays which oxtend from one side of the
hood to the other at the point of junction of the wings and the curved part of the
hood. These stays or cross pieces rest upon the apex or ridge of the stack and
maintain the hood above it in the same manner as the cross bars or ties herein-
before mentioned with reference to the arrangement first described.
Instead of being made with wings the hood may be made without them and the
roofing plates attached to the lower ends of the hood.
At Figs: 3 and 4, is represented, at an enlarged scale, a convenient form of peg or
spikes for use in securing metallic roofing, such as is above described, upon a stack.
Such spikes are represented also as Fig. 2. Towards the lower end of the spike there
is pivotted thereto à diamond-shaped wedge or tongue e, the spike being recessed to
receive it. The tongue e is free to turn on its pivot, and when the spike is being
driven into the stack the wedge is made to assume the position shown at Fig. 3, that
is to say, it offers no additional material obstruction to its penetration. But when an
upward or outward strain is exerted upon the spike tending to withdraw it, the tongue
or wedge e assumes a position crosswise on the spike as seen at Fig. 4 and resists.
withdrawal. The roofing sheets of stacks are therefore securely held in place upon
the stack by such spikes.
Having now particularly described and ascertained the nature of this invention, and
in what manner the same is to be performed, I declare that what I claim is :-
1. The use, in combination with galvanized corrugated iron sheets as roofing for hay
and other stacks, of a hollow hood or ridge piece such as a open at the end and placed
parallel with the ridge above which it is maintained by spiked frames such as band
cross stays such as, or their equivalents, and constituting a continuous air space for
free ventilation at the top of the stack, and having linked or otherwise connected
thereto, or to wings made thereon, the roofing sheets, substantially as hereinbefore
described with reference to Figs. 1 and 2 of the accompanying sheet of drawings.
2. The use, in combination with galvanized corrugated iron sheets as roofing for
hay and other stacks, of a hollow hood or ridge piece such as a open at the ends and
placed parallel with the ridge or apex of the stack and maintained in place above the
ridge by cross stays placed at intervals across the lower part of the hood, substantially
as described.
3. The use for securing galvanized corrugated sheet iron roofing upon hay and
other stacks, of a spike provided at a convenient point on its length with a wedge
pivotted to the spike and so arranged as not to materially obstruct penetration of the
substance of the stack by the spike, but by turning on its pivot to resist withdrawal
thereof, substantially as herein before described with special reference to Figs. 3
and 4, of the accompanying drawings.
