IN APPARATUS FOR MIXING AND ELEVATING SUGAR IN COURSE OF MANUFACTURE
OR FOR ANALOGOUS PURPOSES" to be as follows:-
The improved apparatus constituting this Invention is principally applicable to
the mixing and elevating of massecuite and other like saccharine products prior to
their treatment in the centrifugal machines or turbines but it is also applicable
for treating other pasty or semi fluid materials-By the employment of the said
apparatus the cost of labour and waste of sugar involved in charging turbines
by hand are entirely obviated.
In carrying out this Invention the apparatus is provided with a hopper into
which the materials to be mixed and elevated are thrown and from which the said
materials are supplied to a cylinder provided with helically arranged teeth passing
between rows of corresponding stationary teeth on the sides of a casing enclosing
the said cylinder-This casing communicates with a pump containing a long piston
or plunger and provided with a valve box connected to a pipe or conduit leading
to the turbines or other receptacles.
The pump piston is driven by a suitable motor or through a belt and transmission
gear and by means of a belt and gearing or other suitable arrangement motion may
also be given therefrom to the wheel of the. mixer-All the parts of the apparatus
are preferably supported on one base plate.
The hopper of the apparatus being charged with massecuite for example the
materials after being acted on by the mixing cylinder pass into the chamber of the
pump when the piston after producing a vacuum in the said chamber during its
back stroke uncovers an orifice connecting the said chamber with the casing of the
mixing cylinder. The piston after it has passed this orifice during its reverse
stroke then forces the materials through the valve box along the discharge conduit
or pipe into the turbines or other receptacles.

The valve in the valve box is provided with a rod or handle projecting through
the cover of the valve box for the purpose of enabling the valve to be loosened
from its seat in case it happens to stick after the apparatus has been out of use.
This apparatus may be stationary or permanently fixed in any convenient part
of the works or it may be mounted on travelling wheels and it may be provided
with a motor for imparting thereto locomotive motion and motion to the working
parts.
In this case (if a steam motor be used) the working parts of the apparatus are
arranged in the manner hereinbefore described but the base plate is preferably
provided with a steam cylinder at one side from which by means of a connecting
rod motion is imparted to a crank disc keyed upon one extremity of the shaft
herein before referred to which transmits motion to the mixing apparatus and
pump. The same base plate may also carry a boiler or generator for supplying the
engine with steam or the steam to work the engine may be supplied by pipes
connected with the steam pipes of the works or if preferred motion may be
imparted to the portable apparatus by means of belts and pulleys as in the case of
the stationary apparatus.

Gentleman do hereby declare the nature of said Invention for "IMPROVEMENTS
IN APPARATUS FOR MIXING AND ELEVATING SUGAR IN COURSE OF MANUFACTURE
OR FOR ANALOGOUS PURPOSES" and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement :-
The improved apparatus constituting this Invention is principally applicable to
the mixing and elevating sugar in the state of massecuite and other like saccharine
products prior to their treatment in the centrifugal machines or turbines but it is
also applicable for treating other pasty or semi fluid materials-The employment of
the said mixing and elevating apparatus is attended with considerable advantage
in the manufacture of sugar as the expense of conveying the sugar from the backs-
to the centrifugal apparatus by hand is entirely obviated the mixing apparatus
being arranged to receive the sugar directly from the backs or other receptacles
and to mix elevate and deliver it directly to the centrifugal apparatus The
materials are thus transferred from one apparatus to the other without the
intervention of hand labour and without that waste of materials which inevitably
attends the operation of charging the centrifugal machines by hand.
The improved apparatus hereinafter described enables the materials that are to
be treated in the centrifugal machines, or turbines to be mixed and elevated with
facility and economy and may be either permanently fixed in the vicinity of the
backs or receptacles containing the said materials or mounted on wheels so as to
enable it to be readily moved from place to place.
This apparatus consists essentially of a forcing apparatus or pump acting in
combination with a pugging or mixing cylinder which stirs and mixes the
materials and reduces them to a state fit to enable them to pass readily through
the pump.
The apparatus can stand at a very small elevation from the ground and
consequently admits of being fixed and charged with great facility-It occupies
but little space and the cost of its construction is not great.
When the apparatus requires to be moved frequently in order to be brought up
close to the backs or receptacles containing the masṣecuite or materials that are to
be mixed and elevated or transferred to the centrifugal machines or other apparatus
it is preferably mounted on wheels and actuated by a small independent engine
supplied with steam either by means of a pipe capable of being readily connected
and disconnected with or from steam supply pipes of the works or by a small
independant boiler attached to the apparatus.
And in order that the said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheets of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figures 1. 2 and 3 of the accompanying drawings represent respectively a
longitudinal section, a plan and a transverse section of a stationary mixing and
elevating apparatus constructed according to this Invention.
Figure 4 is a side elevation of a portable apparatus provided with an independent
engine Figure 5 is a plan and Figure 6 an end elevation of the same.
Referring to figures 1. 2 and 3 A is a bopper into which the materials to be
mixed and elevated are delivered and from which the said materials are supplied to
a cylinder B rotating on a shaft c and provided with helically arranged teeth or

page_text: pegs 6 on its periphery passing between rows of corresponding stationary teeth b¹
on the sides of a casing a enclosing the said cylinder.
.
This casing communicates through an opening or passage E with a horizontal
pump C. containing a long piston or plunger D and provided with a valve F
communicating with a pipe or conduit G leading to the turbines or other
receptacles.
Motion is imparted to the pump piston D in any suitable way. As shewn in the
drawing it is imparted by a cranked shaft h provided with a toothed wheel H
gearing with a pinion i upon a shaft I driven by suitable driving pulleys L-The
shaft I also carries a pulley M transmitting motion by means of a belt to a pulley N
figure 3 connected with a pinion O in gear with a toothed wheel P on the shaft c
of the mixing cylinder B-All the parts of the apparatus are preferably supported
on one base plate Q.
. The hopper A being charged with the material (massecuite for example) which
may be supplied in a continuous manner mechanically by gravitation or otherwise
the materials after being acted upon by the mixing cylinder B pass into the
chamber of the pump C. when the piston D after producing a vacuum in the said
chamber during its back stroke uncovers the orifice connecting the said chamber
with the casing a of the mixing cylinder-The piston after it has passed this
orifice during its reverse stroke then forces the materials through the conduit or
pipe G into the turbines or other receptacles-The piston D then describes another
back stroke and the same operations are repeated a fresh supply of materials being
forced into the pipe G at each revolution of the crank shaft h-The valve F is
provided with a rod or handle f figure 1. projecting through the cover of the valve
box for the purpose of enabling the valve to be loosened from its seat in case it
happens to stick.
In certain cases it is more convenient to employ an apparatus mounted on
travelling wheels T as illustrated in figures 4. 5 and 6 and provided with an
operating engine mounted as part of the vehicle.
In the arrangement illustrated the principal working parts are arranged in the
manner hereinbefore described but the base plate Q is provided with a steam
cylinder R at one side from which by means of a suitable connecting rod motion is
imparted to the crank disc S keyed upon one extremity of the shaft I which
transmits motion to the mixing apparatus through the pulleys M and N and to the
pump through the toothed gear i and H-The same base plate may also carry a
boiler or generator for supplying the engine with steam or the steam to work the
engine may be supplied by pipes temporarily connected with the ordinary steam
supply pipes or if preferred motion may be imparted to the portable apparatus by
means of belts and pulleys as in the case of the stationary apparatus-Hooks U
figure 4 may be provided at both ends of the base plate Q in order to facilitate the
manipulation of the apparatus or locomotive motion may be imparted to the
apparatus when required from the engine which operates the mixing apparatus and
pump.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed' I declare that what
I claim is.
