Year: 1860

page_text: LETTERS PATENT to Henry Cockey and Francis Christopher Cockey, of
the Frome Iron Foundry, in the County of Somerset, Engineers, for
the Invention of "IMPROVEMENTS IN DRIVING CHAFF AND ROOT CUTTERS,
"
Sealed the 7th February 1861, and dated the 9th August 1860.
PROVISIONAL SPECIFICATION left by the said Henry Cockey and
Francis Christopher Cockey at the Office of the Commissioners.of
Patents, with their Petition, on the 9th August 1960.
We, HENRY COOKEY and Francis ChristoPHER COCKEY, of the Frome
Iron Foundry, in the County of Somerset, Engineers, do hereby declarè
the nature of the said Invention for "IMPROVEMENTS IN DRIVING CHAFF AND
ROOT CUTTERS, AND OTHER AGRICULTURAL MACHINES," to be as follows:-
This Invention relates to a peculiar mode of driving chaff and root-cutting
machine, corn-crushers, apple mills, thrashing machines, and other agricul-
tural implements; also, for driving grindstones and rotatory gas exhausters,
whereby such machines may be actuated by steam power direct, without the
intervention of driving shafts and belts.
In applying this Invention to a chaff-cutter, which we prefer to be on what
is known as Corne's principle, we attach a small steam engine to the framing
of the machine; the wheel carrying the knives forms the fly-wheel of the
engine, and its shaft is fitted with a crank, by which it is driven direct from

page_text: the small steam engine secured to the framing. Suitable arrangements may
be made for driving either separately or simultaneously a root cutter or corn
crusher and a small thrashing machine by the same engine by the aid of
jointed rods and couplings or clutches. Or the steam engine may be fitted
on to a separate stand in such a manner that a chaff cutter may be driven
direct by the main shaft on one side, and a root-cutter or other machine ou
the other side, or both may be worked separately on the same side of the
engine.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Cockey and Francis Christopher Cockey in the Great
Seal Patent Office on the 9th February 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
COCKEY and FRANCIS CHRISTOPHER COCKEY, of the Frome Iron Foundry, in
the County of Somerset, Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of August, 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
us, the said l'enry Cockey and Francis Christopher Cockey, Her special
license that we, the said Henry Cockey and Francis Christopher Cockey,
our executors, administrators, and assigns, or such others as we, the said
Heury Cockey and Francis Christopher Cockey, our 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 "IMPROVEMENTS IN DRIVING CHAFF AND ROOT CUTTERS,
AND OTHER AGRICULTURAL MACHINES,' upon the condition (amongst others) that
we, the said Henry Cockey and Francis Christopher Cockey, by an instru-
ment in writing under our hand and seal, 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 filed in the Great Seal
Patent Office within six calendar months next and immediately afterthedate
of the said Letters Patent.
NOW KNOW YE, that we, the said Henry Cockey and Francis Chris-
topher Cockey, do hereby declare the nature of our said Invention, and in

page_text: what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the
accompanying Drawings, and to the letters and figures marked thereon,
that is to say :-
Our said Invention relates to a peculiar mode of driving chaff and root-
cutting machines, corn crushers, malt mills, apple mills, grinding stones,
brick, tile, and pipe-making machines, clay mills, oil cake breakers, thrashing
machines, and other agricultural machines, whereby such machines may be
actuated by steam power direct, the fly wheel of the steam engine being the
fly wheel of the machine to be driven.
In applying this Invention to the driving of a chaff cutter, which we prefer
to be on what is known as Corne's principle, we mount a small steam engine
on the framing of the machine itself. The wheel which carries the knives or
cutters of the machine forms the fly wheel of the engine, and the main shaft
of the machine is fitted with a crank by which it is driven direct from the
small steam engine above referred to. Suitable arrangements may be made
for driving either separately or simultaneously two or more machines; thus a
root cutter, or corn crusher, and a small thrashing machine may all be driven
by the same engine, the fly wheel of any one or more of these machines
serving as the fly wheel of the engine.
And in order that our said Invention may be fully understood, we shall now
proceed more particularly to describe the same, and for that purpose we shall
refer to the several Figures on the Sheet of Drawings hereunto annexed, the
same letters of reference indicating corresponding parts in both Figures.
Figure 1 of our Drawings represents a front elevation of a chaff cutter
arranged so as to be driven direct from a small steain engine in accordance
with our Invention; and Figure 2 is a corresponding plan of the same.
A, A, is the main framing of the chaff-cutter, which may be constructed
either of wood (as shewn in the Drawing) or of iron. Sufficient space is
afforded in this framing for the reception of the bed plate B of a small steain
engine, of which C is the working cylinder, (disposed by preference in a hori-
zontal position, as shewn in the Drawing; D, the piston rod, which is guided
by working through the stationary bracket E bolted to the bed plate; and F
is the forked connecting rod jointed to the crank G, formed on or fitted to the
end of the main shaft H of the chaff-cutter; I is the eccentric for working
the slide valve, and K is a feed pump for supplying the boiler. The main
shaft of the machine, as will be seen on referring to the Drawings, thus forms
the crank shaft of the engine, and receives its rotatory motion direct there-
from without the intervention of gearing or driving belts. The fly wheel L,

page_text: which carries the knives or cutters, is keyed on to the shaft H, and forms also
the fly wheel of the engine. The feed rollers M, M, are driven from the
main shaft by means of the gearing N, and may be thrown out of action
when the machine is not in use by means of the disengaging clutch O. The
feeding part I is made to slide back a short distance so as to be entirely out
of contact with the knives as they rotate, when the machine is not in action
for chaff cutting, leaving the wheel perfectly free and unimpeded to act simply
as a fly wheel to the engine. The engine may then be used for driving
any other machine, which may be connected by universal joints to the
main shaft at H, or by strap to the rigger R."..
In applying this Invention to brick, tile, and pipe-making machines, we do
not confine ourselves to make a rotatory machine, as it may be made in such
a manner that the piston or pistons for forcing the clay through the dies may
be connected to the same rod as the piston of the steam engine, and be
worked cither with or without a fly wheel.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried
into effect, we would observe, in conclusion, that what we consider to be
novel and original, and therefore 'claim as the Invention secured to us
by the herein-before in part recited Letters Patent, is the driving of chaff
and root cutters, corn crushers, malt mills, apple mills, grinding stones,
brick, tile, and pipe-making machines, clay mills, oil cake breakers,
thrashing machines, and other agricultural machines by steam power direct,
as herein-before described.
In witness whereof, we, the said Henry Cockey and Francis Christopher
Cockey, have hereunto set our hands and seals, this Fifth day of
February, in the year of our Lord One thousand eight hundred and
HENRY COCKEY.
