I JEAN QUIRI, of 1 Boulevard St. Denis, Paris, France, Engineer do hereby declare
the nature of this invention to be as follows:-
In the improved refrigerating machines constructed according to this invention the
production of cold is effected by the evaporation of one or other of the following
five novel binary liquids :-
-
1. Anhydrous sulphurous acid, SO³, point of ebullition 10° Centigrade, with
sulphide of carbon, CS, point of ebullition + 46° Centigrade (80 to 90 per cent. of
SO and 10 to 20 per cent. of CS²).
2. Anhydrous sulphurous acid, SO, with isobutylene, CH, point of ebullition -6°
Centigrade.
3. Anhydrous sulphurous acid, SO', with propylene, C³ H, point of ebullition - 30°
Centigrade.
4. Anhydrous sulphurous acid, 80%, with hydride of butyle, CH, point of
ebullition 0° Centigrade.
5. Anhydrous sulphurous acid, SO2, with hydride of amyle, C³ H¹³, point of
ebullition +32° Centigrade.
The ingredients which form these respective liquids can be employed in variable
quantities.
When employed in the refrigerating machine the vapors of the binary liquid are
forced by a compression pump from the refrigerator in which the liquid is evaporated
into a condenser in which they become liquefied, and the liquid is then returned to
the evaporating apparatus and so on.
The improved refrigerating machine is composed of a refrigerator, a compression
pump, a condenser, a circulating pump, and the pipes and valves connecting these
apparatus.
The refrigerator is formed of a series of iron or (preferably) copper tubes placed
parallel to each other in a suitable vessel, containing the brine or salt bath. Outside
this vessel at one end are an upper and a lower collecting pipe and to these two pipes

page_text: which are hereinafter called collectors are respectively connected the two ends of all
the copper tubes; these are of elongated U form. The joints or connections of the
tubes and the collectors being thus outside the brine bath they can easily be attended
to even while the machine is at work. The stuffing boxes through which the tubes
pass are formed in one and the same cast iron plate riveted to the sides of the vessel.
The tubes carry at their ends bronze sleeves or collars threaded externally so as to
receive the stuffing box nuts and the rings or flanges for connecting them with the
collectors. By this arrangement any tube, independently of the others, can be removed
and replaced if necessary without removing the ends of the vessel. The collectors
and the joints are enclosed in an outer case which is removable; this case does not
contain brine but only serves to protect the collectors. The binary liquid enters the
refrigerator by a pipe attached to the lower collector, it becomes evaporated in the
tubes and the vapors are drawn off by the compression pump through a pipe attached
to the upper collector. The circulating pump is connected with the brine vessel and
keeps up a continuous circulation of the brine; a screw or agitator may be employed
in lieu of it. The compression pump is a horizontal double action pump and its
cylinder has a refrigerating jacket through which water circulates. The valves of
this pump are as in other pumps held to their seats by means of springs but to avoid
shocks they are fitted with air or gas buffers or stops.
The condenser is constructed precisely the same as the refrigerator except that in
the refrigerator the binary liquid enters by the lower collector and issues in the state
of vapor by the upper collector, while in the condenser the compressed vapors enter
by the upper collector and after condensation leave by the lower collector. This
similarity of construction between the refrigerator and the condenser is of great
advantage in practice.
The water necessary for condensation enters the reservoir of the condenser at
bottom.

Improvements in Refrigerating Machines and Novel Binary Liquids
to be Used therein.
I JEAN QUIRI, of 1 Boulevard St. Denis, Paris, France, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
In the improved refrigerating machines constructed according to this invention the
production of cold is effected by the evaporation of one or other of the following five
novel binary liquids
:-
1. Anhydrous sulphurous acid, SO³, point of ebullition 10° Centigrade, with
sulphide of carbon, CS, point of ebullition + 46° Centigrade (80 to 90 per cent.
of SO and 10 to 20 per cent. of CS*).
2. Anhydrous sulphurous acid, SO³, with isobutylene, CH³, point of ebullition -6°
Centigrade.
3. Anhydrous sulphurous acid, SO³, with propylene, C³ H*, point of ebullition - 30°
Centigrade.
4. Anhydrous sulphurous acid, SO³, with hydride of butyle, C H, point of
ebullition 0° Centigrade.
5. Anydrous sulphurous acid, SO³, with hydride of amyle, C³ H¹ point of
ebullition +32° Centigrade.
The ingredients which form these respective liquids can be employed in variable
quantities.
When employed in the refrigerating machine the vapors of the binary liquid are
forced by a compression pump from the refrigerator in which the liquid is evaporated
into a condenser in which they become liquefied, and the liquid is then returned to
the evaporating apparatus and so on.
The improved refrigerating machine is represented in elevation in Figure 1 and in
plan in Figure 2 of the annexed drawings and is composed of a refrigerator V, a
compression pump P, a condenser C, a circulating pump p and the pipes and valves
connecting these apparatus.
The refrigerator V is formed of a series of iron or (preferably) copper tubes placed
parallel to each other in a suitable vessel a, b, c, d containing the salt bath. Outside
this vessel at one end are an upper and a lower connecting pipe marked respectively A
and B and to these two pipes which are hereinafter called collectors are respectively
connected the two ends of all the copper tubes; these are of elongated U form. The
joints or connections of the tubes and the collectors A and B being thus outside the
salt bath they can easily be attended to even while the machine is at work. Figure 3
is a sectional view on a larger scale illustrating the joints or connections. The
stuffing boxes through which the tubes pass are formed in one and the same cast iron
plate riveted to the side a, d of the vessel. The tubes carry at their ends bronze

page_text: sleeves or collars (as seen in Figure 3) threaded externally so as to receive the
stuffing box nuts and the rings or flanges for connecting them with the collectors.
By this arrangement any tube, independently of the others, can be removed and
replaced if necessary without removing the ends of the vessel a, b, c, d; this is a
point of great advantage. The collectors and the joints are enclosed in an outer
case a, d, e, f which is removable; this case does not contain the salt liquor but only
serves to protect the collectors. The binary liquid enters the refrigerator by a pipe Ď
attached to the lower collector B, it becomes evaporated in the tubes and the vapors
are drawn off by the compression pump through a pipe E attached to the upper
collector A. The circulating pump p is connected with the salt vessel a, b, c, d and
keeps up a continuous circulation of the salt liquor; a screw or agitator may be
employed in lieu of it. The compression pump P is a horizontal double action pump
and its cylinder has a refrigerating jacket through which water circulates. The valves
of this pump (see the detail view in Figure 4) are as in other pumps held to their
seats by means of springs but to avoid shocks they are fitted with air or gas buffers or
stops s, sl.
The condenser C is constructed precisely the same as the refrigerator V except that
in the refrigerator the binary liquid enters by the lower collector and issues in the
state of vapor by the upper collector, while in the condenser the compressed vapors
enter by the upper collector A¹ and after condensation leave by the lower collector B'.
This similarity of construction between the refrigerator and the condenser is of great
advantage in practice.
The water nécessary for condensation enters the reservoir of the condenser at bottom
and leaves it by the pipe G placed at the upper part.
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 construction of refrigerating machines substantially as hereinbefore described
and represented in the annexed drawings.
2. The special arrangement substantially as herein before described and represented
in the annexed drawings of the tubes and collectors of the refrigerator and condenser
respectively so that their joints or connections are outside the salt bath in the case of
the refrigerator and outside the water reservoir in the case of the condenser and so
that any tube can be removed and replaced independently of the others as set forth.
3. The special arrangement substantially as hereinbefore described and represented
in the annexed drawings of the valves of the compression pump so that while having
springs to hold them to their seats they are fitted with air or gas buffers or stops as
set forth.
4. The several novel binary liquids herein before described for use in refrigerating
machines.
