IMPROVEMENTS IN THE CONSTRUCTION OF PORTABLE SILOS OR RECEPTACLES FOR FODDER, GRAIN OR OTHER PRODUCE
Year: 1884

page_text: 'I EDWARD CORY, of Acorn Works Edward Street Blackfriars London SE in the
County of Surrey, do hereby declare the nature of my Invention for IMPROVEMENTS
IN THE CONSTRUCTION OF PORTABLE SILOS OR RECEPTACLES FOR FODDER, GRAIN
OR OTHER PRODUCE to be as follows:-
I form my silos of wood or any suitable material in a circular form the staves
being erected vertically and held together by bands round the outside; the bands
being drawn tight by suitable lugs and screws so as to tighten the staves one upon
the other like the staves of a barrel-I plane the joints of the staves to suit the
radius of the silo, and should the latter be of large circumference I make the bands
in segments each having its lugs and screws so that the tightening can be carried
on at different points. The bottom of my silo I form of concrete, puddled clay,
wood or any suitable material, and the roof may be made of iron plain or
corrugated, wood, felt, waterproof paper or cloth, thatch or any watertight covering.
I sometimes also construct a door in the side which can be kept airtight by
luting it with clay or in any other convenient way.
To facilitate the erection of the silo I place hooks, screws or pegs on some or all
of the staves to support the bands till they are properly tightened up, and if
necessary the bands may be afterwards screwed or nailed to each stave.

page_text: I EDWARD CORY of Acorn Works, Edward Street, Blackfriars, London in the
County of Surrey, Civil Engineer do hereby declare the nature of my Invention
for IMPROVEMENTS IN THE CONSTRUCTION OF PORTABLE SILOS OR RECEPTACLES
FOR FODDER, GRAIN OR OTHER PRODUCE and in what manner the same is to be
performed, to be particularly described and. ascertained in and by the following
statement
I construct my portable silos in a circular form, with vertical staves of wood or
any other suitable material; these staves should be planed at the edges, bevelled to
suit the radius of the required circle so that the joints may come perfectly together,
and sometimes tongued and grooved or grooved for hoop iron tongues between each
joint to make the structure airtight. The inside and outside of the staves may also
be planed. I then confine the staves to the circle and draw them all tightly
together, with iron bands, having suitable lugs & sorews for tightening the bands.
These bands are placed round the silo at different distances, and, if the silo is of
large diameter, they may be made in sections having two, three or more sets of
lugs and screws in the circumference. The upper and lower bands may be
constructed of angle iron bent to the circle, so that the flange of the angle iron will
form a top & bottom rim or edge to the silo, and so protect and confine the ends of
the staves. The floor or bottom of my silo, I form of concrete, puddled clay, wood,
or any suitable material, and the roof may be made of iron, plain or corrugated,
wood, felt, waterproof paper or cloth, thatch or any watertight covering-I prefer
however making the roof of waterproof canvas, shaped like a tent and carried upon
a crossbeam and centre upright, the sides of the canvas being held to the walls of
the silo with an iron band round the outside and drawn tight with a screw.
If I make the roof of any other material I so arrange it that it can be entirely or
partially removed for filling the silo. I also sometimes construct a door or doors in
the sides of the silo to facilitate the removal of the contents. These doors may be
made of portions of the staves framed together and tongued or jointed to keep
them airtight. In fixing the doors to the silo I prefer to screw them to the sides
with bolts or screws, and to place round and under the frames a band of hay luted
with clay or any other similar material, which, when the bolts are screwed tight,
will form an airtight joint. To facilitate the erection of the silo, I place hooks,
staples, screws, pegs or other similar fastenings on some or all of the staves to
support the bands till they are properly tightened up, and I sometimes screw or
nail the bands to each stave to keep them in their places. The outside of the silo
should be painted or tarred, and the inside, if constructed of wood, should be
charred with a torch or protected in any other suitable manner from moisture.
With reference to the accompanying drawings, Fig 1. shows my portable silo,
half in elevation and half in section, and Fig 2. is half a plan of same, or section
through A. B. of Fig 1. C. C. are the vertical staves. D. D the bands with their
lugs and screws E. E. F. the door. G the crossbeam for roof with its upright H.
I. I. the waterproof canvas roof held down to the sides of the silo with the band J,
and tightened with the screw K, and L the floor, which may be raised a few inches
above the outside level to keep it dry.
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:-
1* The construction of a portable silo, or receptacle for fodder, grain or other
produce, of vertical staves with planed joints, confined by bands on the outside and
sometimes tongued and grooved to keep it airtight.

page_text: 2nd The construction of the iron bands with lugs and screws for tightening the
staves of a portable silo particularly as described.
3rd The arrangement of the roof and floor for a portable silo substantially as
described.
