I, CHARLES HENRY SANDERS, of Broad Street House, in the City of London,
Gentleman, do hereby declare the nature of this invention to be as follows
This invention has reference to apparatus for separating steam or vapour from
liquids and regulating the discharge of the latter The improved apparatus 18
more particularly applicable for use with apparatus of the kind in which syrup
for use in the manufacture of sweetmeats is forced through an externally heated
tube so as to convert the water in the syrup into steam or vapour, but may be
used with other apparatua
The apparatus comprises a separating chamber into which hot liquid is forced
and which is provided at its lower part with an outlet for syrup and, at its upper
end with an outlet for steam, said outlets being controlled by valves adapted to
be operated by a float within the chamber and so arranged that they cannot
both be fully open at the same time
In one arrangement, the liquid and steam outlets are opposite each other and
the controlling valves are secured to the ends of a vertical spindle to which the
float is attached. The liquid outlet may be connected by means of a suitably
lagged pipe with a cooling tank or vessel and the steam outlet may, in some cases,
be connected with a condenser and air pump Normally the weight of the float
causes the lower valve to close the liquid outlet, leaving the steam outlet open,
but, on the delivery of hot liquid into the separating chamber, the float rises
and gradually opens the liquid outlet. The liquid will enter the chamber more
quickly than it will leave it and the outflow of steam will be checked by the
further raising of the float, thereby causing an increase of pressure in the
separating chamber and consequently a quicker delivery of liquid. As the
chamber begins to empty, the float will fall and allow more steam to escape
To enable the apparatus to be emptied and washed a spindle is provided which
extends through the wall of the chamber and at its inner part is fitted with an
arm and at its outer part with a weighted lever, the inner arm 18 normally held
clear of the valves and float but by raising the weight the arm can be caused_to
lift the float so as to close the steam outlet and open the liquid outlet
inner arm may engage a projecting part of the lower valve The liquid valve
may be of ordinary construction formed with wings and adapted to rest upon a
seating around the outlet aperture. The steam valve preferably comprises a
short tube sliding over an inwardly projecting length of the outlet tube which is
formed with lateral ports or apertures and a closed end, apertures are also formed
in the outer tube to ensure the steam pressure on the float being balanced
The

movement of the float and consequently the pressure arising in the chamber may
be varied
The separating chamber may be fitted with a thermometer, if required.
Improvements in Apparatus for Separating Steam or Vapour from
Liquids and Regulating the Discharge of the Latter, more partiou-
larly applicable for use in the Manufacture of Sweetmeats.
A communication from abroad by EDWARD SHAW, of Westminster Hotel, Irving
Place, New York, United States of America.
I, CHARLES HENRY SANDERS, of Broad Street House, in the City of London,
Gentleman, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention has reference to apparatus for separating steam or vapor from
liquids and regulating the discharge of the latter, and 18 more particularly
applicable for use in combination with apparatus in which syrup for use in
the manufacture of sweetmeats is forced through an externally heated tube so
as to cause the water that 18 contained in the syrup to be evaporated and con-
verted into steam or vapour, but apparatus according to this intention may be
used with apparatus other than of the kind herein before mentioned
The accompanying illustrative diawing shews in vertical section an apparatus
whereby the separation of liquid or syrup and vapour or steam discharged into
it 18 effected, and from which the quid is automatically discharged inter-
mittently
The apparatus comprises a separating chamber 1 into which hot liquid or
ayrup from the externally heated coil of a cooking or concentrating apparatus
18 admitted and which is provided at its lower part with an outlet 2 for syrup,
and, at its upper end with an outlet 3 for steam separated from the syrup, said
outlets being controlled by valves operated by a float within the chamber and
so arranged that both valves cannot be fully open at the same time.
In the arrangement illustrated, the syrup outlet 2 and the steam outlet 3
are placed opposite each other at the ends of the separating chamber 1 and the
valves 4, 5 for controlling the outlet of syrup and steam are secured on the ends
of a vertical spindle 6 to which the float is attached. The syrup outlet 2 18
connected by means of a suitably lagged pipe with a cooling tank or vessel
(not shewn) and the steam outlet 3 may, in some cases, be connected with a
condenser and air pump. The float 7 18 of such a weight as, when the separator
18 empty, to close the valve 4 of the liquid outlet 2, thus leaving the valve 5 of
the steam outlet wide open, but, on delivery of hot syrup from the externally
heated tube of the cooking apparatus by the pipe 8 into the separating chamber 1
the float 7 will rise and gradually open the valve 4 of the liquid outlet 2, thereby
gradually closing the valve 5 of the steam outlet 3 The syrup enters the
separating chamber 1 through the pipe 8 more quickly than it leaves through the

page_text: outlet 2; the outflow of steam being checked by the continued raising of the
float, will cause an increase of pressure in the separating chamber 1 and con-
sequently a quicker delivery of syrup therefrom As the separating chamber 1
empties, the float 7 falls and allows more steam to escape by the outlet 3 Below
the pipe 8 there is fixed a guide plate inside the cover 1* of the separating
chamber 1 to prevent syrup splashing on the valve 5 and also striking the top of
the float 7 thereby preventing the balance and action of the float being disturbed
To enable the apparatus to be emptied and washed a spindle 10 is provided
which extends through the wall of the separating chamber and at its inner part
is fitted with an aim 11 and at its outer part with a weighted lever 12; the
arm 11 is normally held clear of the valve 4 and float 7, but by raising the
weighted lever 12 the arm 11 can he caused to engage a projecting part of
the valve 4 and lift the float so as to close the valve 5 of the steam outlet 3 and
open the valve 4 of the syrup outlet 2. The valve 4 may be of ordinary con-
struction formed with wings'and adapted to rest upon a seating around the outlet
aperture 2. The valve 5 preferably comprises a short tube 5 sliding over an
inwardly projecting length 3 of the outlet tube 3 which is formed with lateral
ports or apertures 3 and a closed end, apertures 5b being also formed in the
outer tube 5 to ensure the steam pressure on the float 7 being balanced
In some cases, one or other of the valve seatings may be adjustable so that the
movement of the float and consequently the pressure arising in the chamber may
be varied
The separating chamber may be fitted with a thermometer 13, if required.
Having now particularly described and ascertained the nature of this in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
1 Apparatus for separating steam or vapour from liquids and regulating the
discharge of the latter comprising a chamber into which hot liquid or syrup 18
admitted, and which is provided at its lower part with an outlet for syrup and at
its upper part with an outlet for steam, said outlets bang controlled by valves
operated by a float within said chamber, and so arranged that both valves are
not fully open at the same time substantially as described.
2 Apparatus for separating steam or vapour from liquid and regulating the
discharge of the latter, constructed arranged and operating substantially as
described with reference to and shown in the accompanying drawing
