TRUVIDIONAL DI MUITIVATION.
Improvements in Corrugated Iron or other Metal Coverings for
Ricks, Thatched Houses, Silos, Hay Barns, or other Roofs.
I, WILLIAM SNAYDON of Corscombe in the County of Dorset, Farmer do hereby
declare the nature of this invention to be as follows:-
The sheets are prepared by being punched with an upward swell or burr at the
four corners and as many other places as desired along the side and edge in such a
manner that they exactly fit each other when placed in position. Into these holos are
inserted screw bolts provided with concave heads bonneting over the holes so as to
prevent the admission of water.
A washer or plugging of lead or other soft substance may be introduced into the
cavity of the head to be compressed into the hole and completely seal the opening.
A nut or strap of iron with a female screw to receive the bolt is rivetted, soldered, or
otherwise fixed to the sheet underneath the holes in the underlying part. By this
means any number of sheets either in length or breadth may be screwed together
forming one complete waterproof piece and accommodating itself to any pitch of roof.
For hanging on Ricks or Thatched Houses the bolts are provided with long spear
points to pass through the nuts and penetrate the roof so as to form a holdfast for
the sheets.
In any parts of a roof where it may be found desirable to place wood underneath,
and the male and female screw may not conveniently serve, a similarly constructed
bolt as to the head but with a woodscrew thread may be made to take the place of the
male and female screw already described.
The ridging may be of any desired form and may be screwed to the sheets in the
same manner as they are to each other.
In covering thatched houses a convenient form of securing the ridge or heap will
be to frame two boards together in the form of an inverted trough to saddle over the
ridge or heap and form a firm fixing for both sides of the roof.
In most cases it will be found unnecessary to employ ridging for ricks as the roof
may be formed in one straight run similar to what is known as a lean-to roof in
buildings a very little rise being sufficient to carry off the water, or, if a double roof

page_text: be formed, one side may be made to slightly overlap the other at the ridge and be
fastened together by means of a saddle iron so arranged as to receive the screw bolts
on either side, or by other suitable appliance. Or a wire chain or stranded wire
rope or other flexible band may be attached to the overlapping part and, being
brought down over the opposite side, be secured by a spear or stake driven into
the rick.
If it is preferred to use ridging for ricks the same may be kept in position by being
provided with prongs barbed curved or of other convenient form made to penetrate
the rick, the outer ends of the ridging as well as the edges of the sheets being kept
from being blown up by means of wires, rods, or small chains attached to eyes or hooks
fastened to the ridge or sheets and secured at the other end by a spear or stake driven
into the rick.
Sheets provided with appliances in manner herein described will also be applicable
to forming coverings for Silos, Hay-barns or other roofs where it may be convenient
to remove a part for the purpose of filling or taking out the contents.
A strong and efficient roof for this purpose would be formed entirely of curved
sheets, long and short sheets being alternately employed to break the joint and give
rigidity to the roof.
This Invention admits of modifications in minor details without departing from the
main features or principles thereof.

COMPLETE SPECIFICATION.
Improvements in Corrugated Iron or other Metal Coverings for
Ricks, Thatched Houses, Silos, Hay Barns, or other Roofs.
I, WILLIAM SNAYDON of Corscombe in the county of Dorset, Farmer, 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 sheets according to my Invention are prepared by being 'punched or having
otherwise formed therein holes at the four corners and as many other places as
required along the sides and edges in such a manner that the several sheets shall
exactly fit each other when placed in position. I prefer to form the holes aforesaid so
as to give the perforations an upward swell or burr as shown more particularly at
figures 1 and 8.
Into the holes aforesaid are inserted screw bolts (figure 2.) provided
with concave heads c. bonneting or covering over the holes so as to prevent the
admission of water.

page_text: A conical washer d. figure 3. or plugging of lead or other soft substance may be
introduced into the cavity of the head to he compressed into the hole, thus absolutely
sealing the opening and making same completely watertight.
A nut (figure 6) or strap of iron e (figure 5.) tapped to receive the bolt bis
rivetted, soldered or otherwise fixed to the sheets underneath the holes in the
underlying part.
The nut may be a small piece of iron or other metal with a female screw, fitted
into the hollow of the corrugation, or may be a strap of iron e. (figure 5.) aforesaid,
running wholly or part way across the sheet for the purpose of stiffening it, and
having a female scrow cut therein at such places as required. By this means any.
number of sheets either in length or breadth may be screwed together forming one
complete waterproof piece and accommodating itself to any pitch of roof.
For hanging on Ricks or Thatched houses the bolts are provided with long spear
points to pass through the nuts and penetrate the roof so as to form a holdfast for
the sheets, (shown more particularly at g figure 3). In any parts of a roof where it
may be found desirable to place wood underneath, and the male and female screw may
not conveniently serve, a similarly formed bolt as to the head but with a wood scrow
thread may be made to take the place of the male and female screw already described.
Return sheets of any desired form and size may be employed to connect the lower
extremities of the sheets at the eaves with the wall plate, thus completely hiding any
thatch from view and preventing the possibility of fire. The bolts connecting the
shoets at the caves may also hold the stay irons for the "shuting" or rain water
guttering. The ridging & figure 1. may be of any desired form and may be screwed
to the sheets in the same manner as they are to each other. In most cases it will bo
found unnecessary to employ the method shewn in figure 1. for ricks as the roof may
be formed in one straight run similar to what is known as a "lean-to" roof; a very
little rise being sufficient to carry off the water, or if a double roof be formed, one side
may be made to slightly overlap the other at the ridge and be fastened together by
means of a saddle iron so arranged as to receive the screw bolts on either side or a
wire chain, stranded wire rope, flexible band or other suitable appliance may be
attached to the overlapping part and being brought down over the opposite side be
secured by a spear or stake driven into the rick.
If it is preferred to adopt the use of ridging for ricks, the same may be kept in
position by being provided with prongs, barbed, curved or of any convenient form to
allow of penetrating the rick, and so form a holdfast for same, or it may if desired be
screwed to the sheets in the manner already described. Said ridging may be of any
kind, bent or curved sheets of metal of the same pitch of corrugation as the straight
sheets before mentioned, or the covering may consist entirely of curved sheets. The
outer ends of the ridging and the edges of the sheets both at the sides and end of the
rick may be kept from being lifted by means of wires, rods or small chains i. attached
to eyes or hooks h. fastened to the ridge and sheets, being secured at the other end j.
by a spear or stake driven into the rick, and in some cases the heads of the bolts may
be provided with a ring or loop shewn figures 4 and 7, the fastening being attached
thereto.
Corrugated sheets provided with the appliances hereinbefore described will also be
applicable to forming coverings for Silos, Hay-barns and other roofs where at any
time it may be convenient to remove a part for the purpose of filling and taking out
the contents, or for any kind of roof or building but more especially for such as
required to be put up or removed expeditiously such as soldier's tents, those for
emigrants and so forth.
Figure 7. is a section of a structural formation having two vertical straight
sheets, forming two sides with a "lean-to" roof connected at the edges by ridging or
connecting iron m. m¹ as shown.
This structure could be put together and taken down in a short space of time and
would form a covering well adapted for soldiers' or emigrants' tents, shelter for sheep
or other animals, by the utilisation of the metal sheets which might readily be applied
when taken from the ricks. Instead however of the sides being of unequal height.

page_text: and a "lean-to" roof as here shown as being adopted, any other form of structure
may be employed; as, straight sides of equal length and curved shoots for roofs, or a
double roof of straight sheets and with curved sheets or other kind of ridging at
the top.
Coverings for Silos, Hay-barns or any open roof may be thus formed preferably by
curved sheets, unequal lengths being employed to break the joint and give rigidity to
the roof. To further effect this I may overlap as many corrugations as desired
and may employ a second strip of corrugated metal so as to treble the thickness at the
overlapping part, the nut or female screw being fixed to the underlying part in as
many corrugations as required.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is :—
First. The preparation of corrugated sheets by punching or otherwise forming holes
in same said holes having preferably an upward swell or burr at the four corners and
as many other places as required along the sides and edges in such a manner that they
exactly fit each other when placed in position, substantially as herein set forth.
Second. The use of a concave headed or bonneting bolt covering the holes formed
in the corrugated sheets referred to in the preceding claim, substantially as herein set
forth and shown more particularly at figs. 2, 3, 4 and 6 of the accompanying sheet of
drawings.
Third. The use of a nut or strap of iron in connection with a female screw rivetted
soldered or otherwise fixed to the sheets underneath the holes in the underlying part,
substantially as herein set forth.
