PROVISIONAL SPECIFICATION left by the said Isaac Henson at the Office
of the Commissioners of Patents on the 26th April 1882.

"IMPROVEMENTS IN BARNS AND SHELTERS WITH RAISING AND FALLING ROOFS "
This invention has for its object improvements in barns and shelters with
raising and falling roofs.
The lifting apparatus consists of a worm and worm-wheel, it works on a cast
iron bracket secured on the top of post as shewn on the sketch.
The worm-wheel is keyed on to the shaft which runs from post to post; there
are two drums on each shaft for carrying the chain or rope for raising or lowering
the roof.
The worm is keyed on a shaft, and is geared with the worm wheel fixed on the
cast iron bracket.
On the worm shaft is fixed a grooved pulley projecting six inches from the post
on this pulley is placed an endless rope by pulling which either right or left, the
roofs are raised or lowered on one side; two of these lifts are required to lift one
or more sections as may be.
The opening caused by the sections of the roofs being at different altitudes is
sheltered with a loose sheet, which partly laps over each section-for the purpose
of keeping out the wet. The loose sheet has a slot in each corner and passes over
an eye bolt which is secured at the corner of each roof a key or wedge is then
passed through the eye bolt over the loose sheet, thus securing it to the roofs.
When either section of the roofs are required to be lowered, the key or wedge is
drawn out, liberating the sheet from the portion to be lowered, the said sheet
remains fast on the upper section of roof.
I also combine a shed for cattle or stock with the hay barn viz: cattle shed
below and barn above as shewn on the sketch

"IMPROVEMENTS IN BARNS AND SHELTERS WITH RAISING AND FALLING ROOFS
"
This Invention has for its object improvements in barns and shelters with
raising and falling roofs.
For this purpose the roof is formed in sections connected by loose sheets. It is
carried by posts at the junction of the sections and at the ends where two sections
meet they slide in grooves on each side of the intermediate posts. The roof can be
raised as a whole or in sections and each section slides in grooves at the sides of
the posts..
The lifting apparatus consists of a worm, and worm wheel it works on a cast
iron brackets, secured on the top of the post.
The worm wheel is keyed on to a shaft which runs from post to post; there are
two drums on each shaft, for carrying the chains or ropes for raising or lowering
the-roof.
The worm is keyed on a shaft, and is geared with a worm wheel fixed on the
cast iron bracket.
On the worm shaft is fixed a grooved pulley projecting six inches from the post.
On this pulley is placed an endless rope, by pulling-which-either-right or left; the
roofs are raised or lowered on one side, two of these lifts are required to lift each.
section one for lifting each side of it.
The opening caused by the sections of the roofs being at different altitudes is
sheltered with a loose sheet which partly laps over each section for the purpose
of keeping out the wet. The loose sheet has a slot in each corner and passes over
an eye bolt which is secured at the corner of each roof, a key or wedge is then
passed through the eye bolt, over the loose sheet thus securing it to the roofs.
When either section of the roofs are required to be lowered, the key or wedge is
drawn out liberating the sheet from the portion to be lowered-the said sheet
remains fast on the upper section of roof.
I also combine a shed for cattle or stock with the hay barn viz-cattle shed
below and barn above.
The drawings hereunto annexed shew the above described improvements.
Figure 1 shews a side view of a barn with its roof in two sections. Figure 2 is
an end view of the same. Figure 3 is an end elevation of the lifting gear fixed on
the top of one of the posts. Figure 4 is a side elevation of the same. Figure 5
is a side elevation of a similar roof mounted above the top of a shed or shelter
for cattle.
In these Figures A are the upright posts-B are the sections of roof formed
preferably of arched corrugated galvanized iron sheets as shown. C is a similar
loose sheet overlapping the junction of the two sections of the roof and which can
be secured to either or both sections as above described.
Dare cast iron brackets fixed to the top of the posts-they carry shafts E.
which run from post to post along each side of the structure. On each length of
shaft are two barrels one near each end. A chain or rope is wound around each
barrel and its end is attached to one end of each roof segment as shown. Each
length of shaft at one of its ends has fast upon it a worm wheel F into this gears
a worm G on a spindle H which is carried in bearings in the bracket D below the
shafts E. The spindle H projects outwards a short distance from the post, and has

page_text: fixed upon it a grooved wheel I over which is passed an endless rope-the rope
hangs down to a convenient distance from the ground so that a man may pull
upon it either on its right or left hand side and by so doing causo the shaft E to
turn in a direction either to raise or lower the side of the roof section which is
suspended from it by chains as above described. Proofs formed of a single section
may be raised and lowered by lifting apparatus of the same construction.
At Figure 5 a roof capable of being raised and lowered as above described is
shewn to be mounted above a floor K which forms the roof of a shed or shelter
for cattle. The floor is carried by the posts A and by other intermediate supports
along the sides.
Having thus described the nature of my Invention and the manner of
performing the same I would have it understood that I claim.-
First. The combination of apparatus substantially as herein before described for
raising and lowering the roofs or sections of roofs of barns and shelter sheds for
stock of all descriptions.
Second. The combination of a barn having a roof capable of being raised and
lowered with a cattle shed or shelter below it substantially as herein before
described.
Third. The construction of the rising and falling roof of a barn in sections with
a loose sheet or portion overlapping the junctions of the sections and with means
for securing the loose sheet or portion to one or other or both sections substantially
as described.
In witness whereof I the said Isaac Henson have hereunto set my hand
and seal this Twenty Fifth day of October in the year of our Lord One
thousand eight hundred and eighty two.
