page_text: LETTERS PATENT to Thomas Potter of Alresford in the County of Hants,
Clerk of Works for an Invention of IMPROVEMENTS IN MACHINERY FOR
COMPRESSING THE MATERIALS USED IN MAKING ENSILAGE
PROVISIONAL SPECIFICATION left by the said Thomas Potter at the Office
of the Commissioners of Patents on the 10th April 1883.
THOMAS POTTER of Alresford in the County of Hants,-Clerk of Works
IMPROVEMENTS IN MACHINERY FOR COMPRESSING THE MATERIALS USED IN MAKING
ENSILAGE
My Invention is intended to facilitate the operation of compressing green crops
and other farm produce in Silos, for making Ensilage, by employing vertical
standards of wrought or cast iron of different sections as may be found most
suitable for the purpose, and having claws or cogs attached thereto, or cast thereon,
the said standards being either built into the outside, or into the insido division
walls of the silos, or into both, when the latter are in course of construction,―or―
fixed thereto after they are built and afterwards used in connection with screw
jacks or hydraulic jacks or presses either severally or in conjunction.--With these
and the before named claws or cogs as the points of resistance, I obtain very great
pressure in a quicker and more economical way than the ordinary methods of
employing dead weights or lever pressure.

THOMAS POTTER of Alresford in the "County of Hants, Clerk of Works
IMPROVEMENTS IN MACHINERY FOR COMPRESSING THE MATERIALS USED IN MAKING
ENSILAGE
Instead of using dead weights or levers for the purpose of effecting great
pressure on green crops when placed in pits or silos for making ensilage for feeding
stuffs for live stock I employ vertical standards of wrought or cast iron of different
sections as may be found most suitable for the purpose and having claws or cogs
attached thereto, or cast thereon the said standards being built either into the
outside or into the inside walls of the silos or pits, or into both inside and outside
walls when they are in course of construction, or fixed thereto after the said
walls are built, and used in conjunction with ordinary screw jacks, or hydraulic
jacks or presses (but the latter by preference) for the purpose of effecting great
pressure.
The object of my invention being to economise the cost of labour and reduce the
time hitherto required for compressing ensilage materials...
In the drawing hitherto annexed E is a plan of a silo or pit in which green
cattle food is deposited A A A A are the channel irons.
F is a vertical section through plan A. A showing how the standards are fixed at
bottom to prevent them being drawn upwards by the action of the press.
G is a section of the same silo or pit, through B. B on plan. D is a section-K a
part vertical section, and L a part elevation of the channel irons A A but drawn
to a large scale.
Having now described the nature of my said invention I wish to be understood
that what I claim is," The means of compressing ensilage materials in pits or
silos by the use of iron standards built or fixed into the walls of the said pits or
silos, and to which irons, are attached iron cogs or fangs for the purpose of
counteracting the pressure obtained by the use of screw jacks hydraulic jacks,
or similar machines.
In witness whereof I the said Thomas Potter have hereunto set my hand and
seal this fourth day of October in the year of our Lord, One thousand eight
hundred and eighty three
