PROVISIONAL SPECIFICATION left by the said Gaston. Charles Ange
Marquis D'Auxy at the Office of the Commissioners of Patents, with his
Petition, on the 28th. July 1860)..
I, GASTON CHARLES ANGE Marquis D'AUXY, of No. 57, Rue Lafayette, iu
the City of Paris, in the Empire of France, do hereby declare the nature
of the said Invention for "AN IMPROVED APPARATUS FOR THE PRESERVATION OF
CORN," to be as follows:-
I propose to construct an apparatus by which large or small quantities of
grain may be preserved from the attacks of nice or insects, and be turned.
over and aired or fumigated with the greatest facility and economy of labour.
In the accompanying Drawing of my proposed apparatus, A represents section
of a cylinder or drum, composed of sheets of more or less perforated metal for
the cylindrical part. The two extremities being closed with metal or wood
(one of them is shewu at B). C, bar or spindle of iron which traverses the
cylinder, and by which it may be supported on horizontal bearings on the
[Price Sd.1

page_text: uprights F, and rotated by hand, or otherwise. For the introduction of the
grain I purpose usually dividing one of the extremities of the cylinder into
two parts, see E, in the Drawing, and I also deem it useful to have a hinged
or grooved opening D in the cylindrical part. By the opening. E at the extre-
mity I half fill the apparatus, and to continue this operation as may be
required I use the opening in the cylindrical part. The grain being in the
apparatus (which I propose terming a silos or granary), on turning it by
placing the hands on the drum or by a crank on the iron bar, I agitate the
grain, air it, and free it from dust. I prefer rotating the cylinder by placing a
bar or handspike in holes G, G₁, G", G, made for that purpose around the
circumference of the extremity of the cylinder. The apparatus may be made
of wood or metal, or partly of either, or of other suitable material, and may be
used for other similar purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Gaston Charles Ange Marquis D'Auxy in the Great Seal
Patent Office on the 25th January 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GASTON
CHARLES ANGE Marquis D'AUXY, of 57, Rue Lafayette, in the City of Paris,
Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of July, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Gaston Charles Ange Marquis D'Auxy, Her special licence that I, the said
Gaston Charles Auge Marquis D'Auxy, my executors, administrators, and
assigns, or such others as I, the said Gaston Charles Ange Marquis D'Auxy,iny
executors, administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention of "AN IMPROVED APPARATUS FOR
THE PRESERVATION OF CORN" upon the condition (amongst others) that I, the
said Gaston Charles Ange Marquis D'Auxy, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to be

page_text: filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Gaston Charles Ange Marquis D'Auxy,do
hereby declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement, reference being also had to the Sheet of Drawings here-
unto annexed, and to the letters of reference placed thereon:-
My method of preserving grain of every description unites in a high degree
all the special advantages which it has been sought to obtain by the several
methods hitherto adopted. Its principal object is, in all latitudes and tem-
peratures, carefully to maintain grain of any quality at a low temperature and
a state of preservation which will not permit the generation or developement
of insects: It further, by its simplicity and economy, asserts a decided supe-
riority over others. For the application and realization of my system I have
imagined, combined, and constructed apparatus, in which may be enclosed
(either in ordinary granaries or other suitable places) an indefinite quantity of
grain, which may be inoved about, aerated, fumigated, and removed to another
receptacle with the greatest facility and the least possible mechanism and
power, and while in such apparatus be protected from insects, mice, heating,
mouldiness, and other deterioration. My apparatus or drum is essentially
composed of sheets of metal (with or without corrugation or fillets) forming
the cylindrical part, and is closed at the two ends with metal or wood. And I
would here observe, that the part of the drum in question may be of other
than cylindrical form, becomposed of flat sheets, and form an octagon, hexagon,
or even a pentagon. This drum, whether it becylindrical or formed of several
flat parts, is traversed by an iron or wooden axle, by means of which it may
be placed horizontally upon supports, there held and set in rotatory motion by
haud, hydraulic, or steam power. To turn this cylinder readily by hand,
cranks may be fitted to the axle, or, preferably, it may be turned by hand-
spikes fitting into cavities formed at the extremity of the circumference of one
or both ends of the drum, and the hand spikes may either be as numerous as,
and remain fitted in the cavities, or may be fewer, and be withdrawn and re-
inserted as the apparatus turns. If the motive power be hydraulic or steam,
the usual gearing, such as bands and pullies will be fitted to the apparatus,
and its movement be regulated at pleasure. For the carriage of the apparatus,
and the introduction of the grain, I usually divide the cylinder into two parts,
but an opening must always be provided in the cylindrical part attached to the
rotation shaft, such opening being closed by a sliding or hinged cover. The
part attached to the axle is first filled, and to continue and terminate this

page_text: operation as required, use is made of the door in the upper part of the cylinder.
The grain once within this granary may, by turning theapparatus, be agitated,
moved about,nerated, fumigated, and freed from any dust and impurity which
it may contain, and also (an advantage never hitherto obtained) prevent all
heating or sweating of the grain, which of itself gives a special value to my
apparatus. According to. requirement and the results to be obtained, the
metallicor wooden parts composing the cylinder may and must be more or less
perforated, and the extreme ends closing the drum may also be perforated.
Lastly, whether to aerate the grain or to submit it to fumigation of any sort,
I traverse or cross the inside of the drum with small cylinders composed of.
sheets of perforated metal, by which (one of their ends being stoppedand closed)
I can introduce and cause to penetrate through the mass of grain such quan-
tity of air or other emanation. as I may desire. The number of these small
tubes (which may be placed parallel or perpendicularly to the axle) may vary:
from two to four; six, eight, orainore, according to requirement and the.size-of
the drum...The air or fumigation may also be introduced, if desired, from the
centre of the cylinder, in which case tubular arms to carry the air.or fumi-
gation through the entire mass of grain will be fitted inside the drum-to a tube
passing through the centre of one or both of the ends.
It will be understood that my method need not always embrace all the
iṇeans.above set forth, but that use may be made of. only such as may be
deemed necessary to meet the requirements of the case.
Amongst other modifications I would especially mention that of leaving the
two parts of the.cylinder open by resting the upper part upon a support. It
will be evident that this apparatus is purely and simply a box or a suspended
sack, of wood or metal, of as low a price as an ordinary sack (calculating from
their relative capacity), and which will last a century, whereas the ordinary
sack. will last.buttwo or three years, therefore, my apparatus becomes in time
infinitely less costly, from its durability and facility of carriage; it may be sold
and resold, let or lent, and, in fact, becomes an implement or reservoir of most..
convenient use..
Further, as this apparatus is intended for commercial use, for inills, for the
navy and land commissariat, as well as for agriculture, its dimensions must
vary accordingly.
In the accompanying Drawings forming part of this my Specification, Aindi-
cates the cylinder of the drum; B, end of cylinder with its opening joined
by hinges with bolts, and by fitting on to their end one or two padlocks, the
apparatus becomes a portable closed granary; C, axle or rotating shaft; D,
opening in the cylindrical part; E,junction of one of the ends of the cylinder;;

page_text: F, F, supports on which the drum is suspended; G, holes for the handspikes;
H. openings for aerating and fumigating; I, handspike; and L, small
cylinder to be placed in the interior for the aeration and fumigation.
In witness whereof, I, the said Gaston Charles Ange Marquis D'Auxy,
have hereunto set my hand and seal, this Twenty-third day of
January in the year of our Lord One thousand eight hundred and
sixty-one.
