PROVISIONAL SPECIFICATION.
Improved Method of and Means for Preserving Grass, Cereals,
Herbage, or other Vegetable Substance, as Ensilage or Food
for Cattle and other Animals.
THOMAS PEARSON, Midland Iron Works, Wolverhampton, Agricultural Engineer,
do hereby declare the nature of this invention to he as follows:-
It consists of the use of a silo, or receptacle, of any form or structure, but sufficiently
substantial, to hold the grass, cereals &c.; and of an exhaust fan, or equivalent
appliance, outside, with pipe passing from inside of silo or receptacle, and connected to
exhaust fan or equivalent appliance.
The exhaust fan may be worked by hand or other power.
When the silo or receptacle has been sufficiently filled with grass, or cereals &c., it
is made air-tight, or nearly so, against admission of outside atmosphere, and, then, the
exhaust fan and pipe are attached to silo to draw off or reduce the internal air or
vapour, to effect the preservation of the contents.
An open and shut-off valve, or tap or stopper is attached to the exhaust pipe; it
serves also to regulato the temperature, or it may be to entirely destroy fermentation,
as may be necessary,
Betwixt top surface of contents and top of silo or receptacle, a vacant space may be
left, after silo or receptacle has been finally closed.
The exhaust or other pipe, may pass through, or into, the contents, or may simply
open into the vacant space referred to, and the latter mode is preferred.
The contents, as filled, may be rolled, or otherwise pressed, for greater compactness
and storeage of materials.
The silo or receptacle may be filled from top or from sides, or otherwise.

COMPLETE SPECIFICATION.
Improved Method of and Means for Preserving Grass, Cereals,
Herbage, or other Vegetable Substance, as Ensilage or Food
for Cattle and other Animals.
THOMAS PEARSON, Midland Iron Works Wolverhampton, Agricultural Engineer,
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:-
It consists of the use of a silo or receptacle, of any form or structure, but sufficiently
substantial to hold the grass, cercals &c.; and of an exhaust fan, or equivalent
appliance, outside, with pipe passing from inside of silo or receptacle and connected to
exhaust fan or equivalent appliance.
The exhaust fan may be worked by hand, or other power-Fig. 1, in drawing.
When the silo or receptacle has been sufficiently filled with grass or cereals &c. it is
made air-tight, or nearly so against admission of outside atinosphere, and then the
exhaust fan and pipe are attached to silo to draw off or reduce the internal air or
vapour, to effect the preservation of the contents-as shown in Fig. 1.
An open and shut-off valve or tap, or stopper is attached to the exhaust pipo as
shown, Fig. 1.
The contents, as filled, may be rolled or otherwise pressed, for greater compactness
and storeage of materials.
The silo or receptacle may be filled from top or from sides or otherwise.

page_text: The silo or receptacle may have outlets or drains for the emission of fluids or
juices from the contents, which outlets are closed air-tight, when exhaust fan is
operating.
Air-tight silos, as hitherto used, alone, & independently, I do not claim.
Exhaust fans, as hitherto used for open-air, unconfined, hay & other stacks, I do not
claim.
Having now particularly described and ascertained the nature of any said
invention and in what manner the same is to be performed, I declare that what
I claim is -
1. The use of a silo or receptacle, of any form or structure, air-tight, or nearly so,
in combination with an exhaust fan or equivalent appliance, and connecting pipe with
valve or tap, to draw off or expel the air or vapour in said silo, for the effective
preservation of the contents, as silage or food for cattle &c., as hereinbefore described
& shown in accompanying drawing, Fig. 1.
2. The use of silo or receptacle, with exhaust fan & connecting pipes &c. as
described in claim 1, but having outlets or drains to open & shut for the emission of
fluids or juices from the contents, as hereinbefore described.
Dated this 10th day of January 1890.
THOS. PEARSON.
