IMPROVEMENTS IN SUGAR MILLS
Year: 1860

page_text: LETTERS PATENT. to Richard Alexander Robinson, of 25, Cannon. Street,
E.C., for the Invention of "IMPROVEMENTS IN SUGAR MILLS."
'PROVISIONAL SPECIFICATION left by the said Richard Alexander
Robinson at the Office of the Commissioners of Patents, with his Petition,
on the 5th January 1860.
RICHARD ALEXANDER ROBINSON, of 25, Cannon Street, E.C., do hereby
declare the nature of the Invention for "IMPROVEMENTS IN SUGAR MILLS,"
to be as follows:-
This Invention relates to that class of sugar mills where the steam engine,
the crushing rollers, and the gearing, are all on the same bed or base plate,
and consists in combining a peculiar arrangement of gearing, with an extension
of the bed or base plate at one side, in order to receive a beam steam engine,
and thus to bring down the gearing and axes or shafts nearer to the base or
bed plate. For these purposes the bed or base plate has an extended or pro-
jecting surface formed on one side, on which the cylinder of a beam engine
is fixed, the further end of the beam by a connecting rod giving motion to a
crank on the main or driving axis or shaft, on which axis or shaft are fixed
pinion, and also a fly wheel. The pinion gives motion to a cog wheel on
an axis, which passes under the beam; such axis- having at its other end a
pinion which takes into and drives a cog wheel, which it is preferred should
have internal teeth, though it may be arranged to have external teeth; this
cog wheel is fixed on an axis or shaft, which by suitable wheels gives motion
to the crushing rollers of the mill, as is well understood.

by the said Richard Alexander Robinson, in the Great Seal Patent
Office on the 4th July 1860.
TO ALL TO WHOM THESE. PRESENTS. SHALL COME, I, RICHARD
ALEXANDER ROBINSON, of 25, Cannon Street, E.C., send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of January, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Richard Alexander Robinson, Her special licence that I, the said
Richard Alexander Robinson, my executors, administrators, and assigns,
'or such others as I, the said Richard Alexander Robinson, 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 SUGAR MILLS," upon
the condition (amongst others) that I, the said Richard Alexander Robinson,
my executors or administrators, 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 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 Richard Alexander Robinson, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
This Invention relates to that class of sugar mills where the steam engine,
the crushing rollers, and the gearing are all on the same bed or base plate;
and consists in combining a peculiar arrangement of gearing with an extension
of the bed or base plate at one side, in order to receive a beam steam engine,
and thus to bring down the gearing and axes or shafts nearer to the base or
bed plate. For these purposes the bed or base plate has an extended or pro-
jecting surface formed on one side, on which the cylinder of a beam engine is
fixed, the further end of the beam by a connecting rod giving motion to a
crank on the main or driving axis or shaft, on which axis or shaft are fixed a
pinion, and also a fly wheel. The pinion gives motion to a cog wheel on an

page_text: axis, which passes under the beam, such axis having at its other end a pinion,
which takes into and drives a cog wheel, which it is preferred should have
internal teeth, though it may be arranged to have external teeth. This cog
wheel is fixed on an axis or shaft, which, by suitable wheels, gives motion to
the crushing rollers of the mill, as is well understood.
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 DRAWING.
Figure 1 shows a side view of a sugar mill and steam engine on the same
base plate, arranged and combined according to my Invention; Figure 2
shows an end view of the sugar mill with its gearing, which differs, however,
slightly from the gearing shown at Figure 1; and Figure 3 shows an end view
of the steam engine, the sugar mill being removed. The bed or base plate a, a,
is formed with an extension b, b, on one side, on which a beam engine of an
ordinary construction is fixed. The construction of steam engine I prefer is
that shown in the Drawing, but the engine itself is not of my invention, and
the construction of beam steam engine used in carrying out my Invention may
be varied. The steam engine, by means of a connecting rod, gives motion to
the crank shaft c, on which is fixed the fly wheel d and pinion e. The pinion e
takes into and drives the cog wheelf on the shaft g, which by means of the
pinion / fixed thereon, gives motion to the wheel i with internal teeth, which
is fixed on the axis of one of the rollers of the sugar mill. It is not essential
that the internal toothed wheel should be employed, and in Figure 2 the
gearing is so arranged, a cog wheel i being used in place of the internal
toothed wheel before referred to. By these combinations or arrangements a
sugar mill is in each case combined with a beam steam engine on the same
bed or base plate, and the gearing is so arranged as to bring the shafts or axes
and gearing near to the bed or base plate. I would state that I make no
claim to any of the parts separately, my Invention consisting in the combina-
tions herein described.
In witness whereof, I, the said Richard Alexander Robinson, have here-
unto set my hand and seal, this Fourth day of July, in the year of
our Lord One thousand eight hundred and sixty.
