I, WILLIAM RICHARD MIDDLEMORE THOMSON, of 262 Bath Street, Glasgow,
in the county of Lanark, Engineer, do hereby declare the nature of my said
Invention for "IMPROVED APPARATUS FOR DECANTING OR TRANSFERRING LIQUIDS
FROM ONE VESSEL TO ANOTHER," to be as follows:-
This said Invention has reference to an improved mode and means or apparatus
for forcing or decanting sugar cane juice or other liquids from one boiling pan or
other vessel into another, which will be much more convenient and economical
than the ordinary modes and means heretofore employed for effecting this by hand
labour or by pumps.
And the nature and-novelty of the improvements of this invention consist as
follows, in the use of a double or reverse conoidal or trumpet-shaped inducing or
lateral acting case or tube for the liquid to be drawn into and forced through, by
the use of a small central or annular steam nozzle fitted in the entering cone near
the throat or narrow part of the inducing tube, for the use of a corresponding jet
of high-pressure steam, or it might be the exhaust steam from a high-pressure
engine when that was convenient, to act on, induce, and force the sugar or other
liquid, whether heated or not, from the lower part of the boiling or other vessel
through the said inducing tube or case up a conducting pipe fitted on the wide
discharge trumpet of the inducing tube. This conducting pipe would be bent
syphon-wise to deliver the liquid as low down as possible in the receiving boiler or
other vessel into which the liquid has to be delivered, so that when the flow of the
liquid is once started it may act on the syphon principle with the use of as little
steam as possible. But when this syphon action is not found necessary or desirable,
the delivery end of the pipe may be cut off at any level and distance beyond the
bend or lowest part of delivery pipe at which it is found most convenient to
discharge the liquid into the receiving vessel. Convenient branch steam pipes aud
a regulating valve would be fitted on the apparatus to lead the steam to its nozzle
at the entrance of the inducing trumpet tube from a fixed main steam pipe. In
some cases the entrance trumpet may be secured to, or formed on, the upper part
of a wide shallow inverted saucer or gong-shaped receiving case or mouthpiece set
with its rim edge on the inner surface and hottest part of the boiling vessel, so that
the boiling action going on within this wide shallow inverted mouthpiece will

page_text: assist in forcing the liquor through the inducing trumpet tube and syphon or
delivery pipe, and so require a less jet of steam. Holes would be formed round the
outer part or perimeter of this receiving mouthpiece for the entrance of the liquid
from the boiler to it. This apparatus inay either be erected stationary between the
boilers or vessels it is required to discharge the liquid from and into, or it may be
hinged by its service branch pipe from the main supply steam pipe, or otherwise, so
as to automatically shut off the steam, and be counterbalanced by a chain and
weight, so as to be easily swivelled and removed out of the boilers or vessels when
not in use, or when the vessels are being cleaned.
In some cases the apparatus and its counterbalancing or raising and lowering
gear, might be hung and fitted on a light wheeled frame to travel on a longitudinal
rail or rails over the range of boilers, so as to be traversed over and lowered into
any two boilers it was required for the time being. The service steam pipe in this
case would be made flexible, or so jointed telescopically or otherwise to the main
steam pipe as to admit of this portable motion of the apparatus.

I, WILLIAM RICHARD MIDDLEMORE THOMSON, of 262 Bath Street, Glasgow
in the county of Lanark, Engineer, do hereby declare the nature of my invention
for "IMPROVED APPARATUS FOR DECANTING OR TRANSFERRING LIQUIDS FROM
ONE VESSEL TO ANOTHER," and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
My invention has reference to an improved mode and means or apparatus for
forcing or decanting sugar liquids or cane juice, or other liquid, from one boiler,
pan, or other vessel, into another; which will be much more convenient and
economical than the ordinary modes and means heretofore employed for effecting
this by hand labour or by pumps.
My invention is illustrated by the accompanying Drawings in which Figures'l
and 2 are respectively a longitudinal and transverse section, and Figure 3 a plan
corresponding to Figure 1, of two pans X, Y, of a set of ordinary open sugar
boilers or pans erected in their brickwork Z, and showing a general arrangement
to a small scale of my improved apparatus or appliance fitted thereto for decanting
or raising and forcing the sugar liquid from one vessel X into the other Y.
Figures 4 and 5 are a sectional elevation and end view detached of the lateral
action induction trumpet case or tube A A¹, with the central acting steam jet

page_text: nozzle a for being regulated from the outer end, all to a larger scale to show the
details of construction more clearly than seen in the general arrangement Figures 1
to 3. Figure 6 shows a sectional elevation of the same parts corresponding to
Figures 4 and 5, but having the steam jet nozzle a¹ onclosed with open ond and
regulated on the inside.
Figure 7 shows a sectional elevation or plan of the said lateral acting
trumpet A, A', with annular steam jet or orifice a round a centre nozzle A³,
through which in this case the sugar liquid passes to the induction trumpet A A¹;
while Figure 8 is an elevation of the nozzle arrangement shown in Figure 7, but
with the "blow-up" cap arrangement C as fitted thereto, but which may be fitted
in an equivalent manner to any of the other arrangements shown in Figures 1 to 5,
or Figure 6.
The darts show the acting direction of the steam in the steam pipes and other
parts where shown, and the arrows indicate the direction of the flow of the sugar
or other liquid through the apparatus.
Referring to Figures 1 to 5 the nature and novelty of the improvements of my
Baid invention consist as follows:-In the use of a double or reverse conoidal or
trumpet shaped inducing or lateral acting case or tube A A¹, for the liquid (as a) to
be drawn into and forced through, by the use of a small central steam nozzle a
Figures 1 to 5, or a Figure 0, screwed or fitted adjustably in the entering end of
the cone A near the throat or narrow part of the inducing tube A, A', for the use
of a corresponding central jet of high pressure steam, or it might be the exhaust
steam from a high pressure engine when that was convenient, as shown in Figures 1
to 6, or it might be by an annular nozzle orifice a³ Figures 7 and 8, and corre-
sponding annular steam jet, to act on or induce and force the sugar or other
liquid z, whether heated or not, from the lower part of the boiling or other
vessel X, through the said inducing tube or case A A¹ up a conducting pipe B fitted
on the wide discharge trumpet end A' of the inducing tube. This conducting pipe
would be bent at the upper part B' syphon wise downwards to conduct the liquid
down the delivery tube B' and discharge it as low as possible in the receiving
boiler or other vessel Y, into which the liquid has to be delivered; so that when
the flow of the liquid is once started it may act on the syphon principle with the
use of as little steam as possible. But when this syphon action is not found
necessary or desirable, the delivery end B³ of this pipe B B¹ B' may be cut off at
any desired level and distance beyond the bend B, or the lowest part of the
delivery pipe B at which it is found most convenient to discharge the liquid into
the receiving vessel Y. Convenient branch and service steam pipes 61, 6º, 6º, and
stop and regulating valves c, o³, would be fitted on these pipes of the apparatus to
lead the steam to its nozzle a, a' or a³ at the entrance of the inducing trumpet
tube A A', from a fixed main steam pipe b. In some cases the entrance trumpet A A¹
(whether fitted with a central, or an annular steam nozzle and jet) may be secured
to, or formed on, the upper part of a wide shallow inverted saucer, gong, or cap-
shape receiving case or "blow-up" mouthpiece C, set with its rim edge down on
the inner surface and hottest part of the boiling vessel ✗, so that the boiling action
going on within this wide shallow inverted mouthpiece Ċ will assist in forcing or
blowing up the liquor into and through the inducing trumpet tube A A¹ and
syphon or delivery pipe B, B1, B2, and so require a less jet of steam to decant or
force the liquid from the one vessel into the other. Holes C¹ would be formed at
intervals round the outer rim part or perimeter of this receiving and "blow-up'
mouthpiece for the entrance of the liquid from the boiler to it. This improved
arrangement of apparatus as shown in Figures 1 to 3 may either be erected
stationary, between the boilers or vessels X, Y, it is required to discharge the liquid
from and into, or it may be binged at its service steam branch and pipe b², 63, from
the main supply steam pipe b, or otherwise, or so as to automatically shut off the
steam by the stop valve or tap c when raised, and open it when lowered, and be
counterbalanced by a chain D, passed over a pulley d with weight D¹, secured by a
carrying bracket D to the back wall Z of the brickwork Z, all so that the
33

apparatus may be easily swivelled up and removed out of the boilers or vessels
when not in use, or when the vessels are being cleaned, as indicated in Figure 2.
In some cases this apparatus and its counterbalancing or raising and lowering
gear, might be hung and fitted on a light wheeled frame to travel on a longitudinal
rail or rails over the range of boilers, so as to be traversed longitudinally over, and
lowered into any two boilers it was required to operate for the time being. The
service steam pipes of the apparatus b', b², would in this case be made flexible, or
so jointed telescopically or otherwise, to the main steam pipe b, as to admit of this
longitudinal portable motion of the apparatus.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The general arrangement, or combination of parts of apparatus for decanting
or transferring sugar or other liquids from one boiler or other vessel to another,
substantially as herein described in reference to and shown in the accompanying
Drawings.
