IMPROVEMENTS IN MACHINERY USED IN CRUSHING SUGAR CANES
Year: 1862

page_text: LETTERS PATENT to George Buchanan, of Bucklersbury, in the City of
London, for the Invention of "IMPROVEMENTS IN MACHINERY USED IN
CRUSHING SUGAR CANES."
Sealed the 2nd June 1863, and dated the 15th December 1862.
PROVISIONAL SPECIFICATION left by the said George Buchanan at the
Office of the Commissioners of Patents, with his Petition, on the 15th
December 1862.
I, GEORGE BUCHANAN, of Bucklersbury, in the City of London, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN MACHINERY USED IN
CRUSHING SUGAR CANES," to be as follows:-
This Invention has for its object improvements in machinery used in
crushing sugar canes, and is applicable in constructing that class of machinery
wherein an oscillating steam engine is used on the same bed or base plate as
the crushing rollers.
Heretofore the oscillating steam engine has been erected near one end of
the bed or base plate and the fly wheel has been situated between the steam
engine and the crushing rollers by which the crank or driving shaft, and the'
framing which carries the same are necessarily elevated considerably above
the base or bed plate.
Now, according to my improvements, I combine an oscillating steam engine
with the crank or driving shaft on which the fly wheel is fixed, and with the

page_text: crushing rollers in such manner that the oscillating engine is placed between
the fly wheel and the crushing rollers, and the fly wheel is caused to be beyond
the end of the bed or base plate, and it descends partly below the end of such
plate. By thus combining the machinery the position of the crank or driving
shaft of the engine, and the framing which supports the same, are considerably
reduced in height from the base or bed plate, and the arrangement of the
machinery is generally improved. For these purposes the oscillating steam
engine is placed between the fly wheel and the large cogged wheel which
is by preference furnished with internal teeth, but this is not essential. The
crank or driving shaft turns in bearings on a suitable framing between the
engine and the fly wheel, and the crank or driving shaft by a pinion thereon
communicates motion to a cog wheel on a shaft which has fixed on it a
pinion which takes into and drives the large cog wheel which gives motion
to the crushing rollers as heretofore.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Buchanan in the Great Seal Patent Office on the
15th June 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
BUCHANAN, of Bucklersbury, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of December, in the year of
our Lord One thousand eight hundred and sixty-two, in the twenty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said George Buchanan, Her special licence that I, the said
George Buchanan, my executors, administrators, and assigns, or such others
as I, the said George Buchanan, my 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 for
"IMPROVEMENTS IN MACHINERY USED IN CRUSHING SUGAR CANES," upon the condition
(amongst others) that I, the said George Buchanan, my executors or adminis-
trators, 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

page_text: cause the same to be 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 George Buchanan, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object "Improvements in Machinery used in
Crushing Sugar Canes," and is applicable in constructing that class of
machinery wherein an oscillating steam engine is used on the same bed or
rollers.
Heretofore the oscillating steam engine has been erected near one end of
the bed or base plate, and the fly wheel has been situated between the steam
engine and the crushing rollers by which the crank or driving shaft, and the
framing which carries the same are necessarily elevated considerably above the
base plate as the crushing base or bed plate.
Now, according to my improvements, I combine an oscillating steam engine
with the crank or driving shaft on which the fly wheel is fixed and with the
crushing rollers in such manner that the oscillating engine is placed between
the fly wheel and the crushing rollers, and the fly wheel is caused to be beyond
the end of the bed or base plate, and it descends partly below the end of such
plate. By thus combining the machinery the position of the crank or driving
shaft of the engine, and the framing which supports the same are considerably
reduced in height from the base or bed plate, and the arrangement of the
machinery is generally improved. For these purposes the oscillating steam
engine is placed between the fly wheel and the large cogged wheel which is
by preference furnished with internal teeth, but this is not essential. The
crank or driving shaft turns in bearings on a suitable framing between the
engine and the fly wheel and the crank or driving shaft by a pinion thereon
communicates motion to a cog wheel on a shaft which has fixed on it a pinion
which takes into and drives the large cog wheel which gives motion to the
crushing rollers as heretofore.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side elevation, and Figure 2 a plan of so much of the
machinery used for crushing sugar cane as will enable me to describe the com-
bined arrangement of the parts according to my Invention. A is the oscillating

page_text: cylinder of a steam engine by which the crushing rollers are driven. The
piston rod of the steam cylinder A gives motion to the crank or driving
shaft B. On the outer end of this crank or driving shaft B, is the fly wheel C,
which it will be seen is beyond the end of the bed plate, which arrangement
admits of the driving shaft B being brought down nearer to the bed plate D,
than could be the case when the fly wheel was placed intermediate of the
oscillating steam engine and the crushing rollers E, E, as was formerly the
practice when driving crushing rollers by an oscillating steam engine. On the
driving shaft B is a toothed pinion F which takes into and drives the cog
wheel G,
which is on the axis H on which there is also a toothed pinion which
takes into and drives the cog wheel I, which wheel is formed with internal
teeth. The axis of the wheel I gives motion to one of the crushing rollers E, E,
in the ordinary manner.
From the above description it will be seen that the oscillating steam engine
is placed between the crushing rollers and the fly wheel, by which arrangement
not only is the fly wheel placed beyond the end of the bed plate and the height of
the driving shaft above the bed plate reduced, but the driving gear and framing
are more advantageously combined with the bed plate, and the crushing rollers,
by which the great vibration to which like machinery has been subjected is
got rid of, whilst the bearings and other parts are rendered more accessible, by
which the machinery is rendered less liable to wear.
Having thus described the nature of my Invention, and the manner of
performing the same I would have it understood that I make no claim to any
of the mechanical parts separately, but what I claim is, the mode herein
described of combining such parts, whereby the oscillating cylinder of the steam
engine is placed intermediate of the fly wheel and the crushing rollers.
In witness whereof, I, the said George Buchanan, have hereunto set
my hand and seal, this Thirteenth day of May, in the year of our
Lord One thousand eight hundred and sixty-three.
