APPARATUS FOR PRESERVING SUBSTANCES FROM BECOMING HEATED OR MOULDY
Year: 1884

page_text: I, WILLIAM HENRY BARNARD Gladfield House Dudbridge, Stroud, Gloucester-
shire, Reed-maker do hereby declare the nature of my invention for an APPARATUS
FOR PRESERVING SUBSTANCES FROM BECOMING HEATED OR MOULDY to be as
follows:-
This invention is a modification of the invention for which a patent (No 4436)
has been granted to me, it consists of one cylinder only, with perforated ends, and
with perforations round the body of it. Spindles are fitted in each of the
perforated ends to form its axis, these spindles run in the bearings of stands made
for that purpose, thereby the cylinder and contents may be turned most easily
either automatically or otherwise.
Substances liable to become heated or mouldy from lying in one position may be
kept sweet and free from mouldiness much longer if placed in the cylinder than if
placed in an upright receptacle, because that in the cylinder may be turned so
easily, one half turn of the cylinder causing it to change its position completely,
while that in an upright receptacle remains stagnant, unless a certain amount of
labour be expended in taking it out to turn it and again to replace it.
Corn, which appears to be of such a dry nature will, from lying in bulk in one
position sometimes become so heated as to be almost spoilt, this is sometimes the
case with a ship's cargo of corn. If my invention could not be successfully applied
to a ship's hold, it would undoubtedly be an advantage to place corn so heated in
large cylinders immediately it came from the ship and then keep it turned until
all signs of heating has disappeared, this would save having to place it in the open
dockyard and then to have it shoveled from heap to heap for the purpose of letting
the air pass through it, which I myself have seen done. Moreover it would be
safe against the pilferings of rats and mice as well as birds.
A capital idea of the principle of my invention may be obtained by placing
equal quantities of Indian corn, barley, and wheat one above the other in a glass
cylinder but not quite filling it, then make it revolve as a cylinder would upon its
axis, the result as seen through the glass is, that that which was in the centre is
about equally distributed amongst the others, showing conclusively that every
particle (in the case of corn) must ultimately come to the side of the cylinder, thus
making it impossible for the contents to become heated if the cylinder be turned.
The perforations round the cylinder is for the purpose of admitting air to the
contents of the cylinder.

I, WILLIAM HENRY BARNARD Gladfield House Dudbridge Stroud Gloucester-
shire Reed maker do hereby declare the nature of my invention for APPARATUS
FOR PRESERVING SUBSTANCES FROM BECOMING HEATED OR MOULDY and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :—
This Invention is a modification of the invention for which a patent (N° 4436)
has been granted to me it consists of one cylinder only with perforated ends and
with perforations round the body of it. Spindles are fitted in each of the
perforated ends to form its axis these spindles run in the bearings of stands made
for that purpose thereby the cylinder and contents may be turned most easily
either automatically or otherwise.
Substances liable to become heated or mouldy from lying in one position may be
kept sweet and free from mouldiness much longer if placed in the cylinder than if
placed in an upright receptacle because that in the cylinder may be turned so
easily, one half turn of the cylinder causing it to change its position completely
while that in an upright receptacle remains stagnant unless a considerable amount
of labour be expended (compared to the ease with which the contents of a cylinder
may be turned) in taking it out to turn it and again to replace it.
The substance to be preserved must be placed in the cylinder, the cylinder being
made to revolve upon its axis by automatic or other suitable means six or eight
times (more or less) during 24 hours for the purpose of turning such substance.
The cylinder must not be filled to its utmost capacity in the case of hard
substances neither may soft or spongy substances (such as herbs and the like) be
pressed in tight, because it is desirable that the contents of the cylinder should be
at liberty to fall apart when the cylinder is turning.
The cylinder may be constructed of tin, zinc, sheet or cast iron, earthen-ware
or other suitable material or materials and for the purpose of giving extra strength
to the cylinder when extra strength is required, instead of spindles being fitted in
the ends of the cylinder as aforesaid, a rod or shaft may be run right through the
cylinder from end to end, leaving a sufficient length of the said rod or shaft
projecting through each end to run in the bearings of the stands.
•
It is not necessary to have the cylinder made to any exact scale or shape, the
length may be equal to the diameter or it may be oblong and the shape may be
round, square, octagon, or otherwise with substantially the same result, and some-
times the receptacle may have compartments for the purpose of holding more than
one class of substance, without altering the general principle of the apparatus.
The perforations may be two or three inches apart (more or less) and sufficiently
small to prevent the substance to be contained in the cylinder from falling through,
these perforations are for the purpose of admitting air to the contents of the
cylinder.
In refering to the Drawing

page_text: 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
A perforated cylindrical receptacle, so fitted at the ends that it may revolve
upon its axis, for the purpose of turning over and over the substance which may
be placed within it. The said receptacle sometimes having compartments for the
purpose of holding more than one class of substance.
