Improvements in Tubular Refrigerators.
HENRY ALMA HETHERINGTON, 6 Southfield Street Arboretum Worcester,
Tin Plate Worker, do hereby declare the nature of this invention to be as
follows:-
The object of my improvements in tubular refrigerators is to make a refrigerator,
which shall quickly cool liquides, & other similar purposes, by there passing a
current of cool air throught the pipes, in addition to the cold water.
In carrying out my invention, I construct the pillars of the refrigerator,
with apertures through, one, above another, & inside, the pillar. I leave an
opening, between two of these apertures, & then stop the passage, & so on the
whole length, of the required pillar, with either an inlet, or an outlet, thereto, at
the top, or bottom.
Each pillar, is so constructed, with flanges at the apertures, so as to carry the
ends of an inner, & an outer, double tube, & also to facilitate, the flow of the water,
or other liquide, through all the tubes, in travelling from side, to side, of the
refrigerator.
I make a double tube, an inner & au outer tube, as one tube within the other,
the inner tube is longer than the out side tube, or both ends of the inner tube
protrude, & the ends of these tubes are fixed into the apertures in the pillars & a
current of cold air always passes through the inner tube which is open at both
ends for that purpose.
I take one, of these double tubes, & put the protruding ends of the inside tube,
through the front apertures in two pillars, standing opposite to each other-& the
ends lodge themselves, upon the Hanges outside going through the apertures,
which flanges, are smaller, than the flanges of the front entrance, the ends of the
outside tube, are lodged upon these front flanges of the apertures, & I solder or
braze or otherwise fasten the ends of the double tube to these flanges of the pillars
also attach, as many double tubes, as there are apertures, in the pillars-thus
making my improved refrigerator.
Operation the double tubes, being joined, to the two pillars, with the inlet &
outlet pipes, & placed in working position, the cold water enters the inlet pipe,
& rushes into the opening in the pillar & flows between the space, of the inside, &
outside, tubes, to the other pillar, & rises inside, the pillar, between the opening
in the two apertures of the pillar-& flows along the next double tubes, & so on to
the top, of the refrigerator to the out let pipe pipe-also the cold air is passing
through the inner tubes which are opened, at both ends, thus keeping the tubes, or
pipe, perfectly cold, imparting coldness to the heated liquides flowing over the tubes-
either for the use of brewer's distiller's worts & other fluides. The condensing of
steam, the cooling & condensing of spirits in distilleries, or in cooling milk, & such
like purposes.
It is understood I shall use any kind of metal, for making the pillars & tubes as
brass, copper, tin & such like-also I shall shape my tubes in any form-so that
the beer or other fluides shall easily pass over them without sagging.

page_text: HENRY ALMA HETHERINGTON, 6 Southfield Street Arboretum Worcester
Tin Plate Worker, 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:—
The object of my improvements, in refrigerators is to make a tubular refrigerator
which shall quickly cool liquids, by the admission of a current of cool air through
the pipes in addition to the cold water.
In carrying out my invention, I construct the pillars of the refrigerator, with
apertures through them, one above another, & inside the pillars I leave an opening
between two of these apertures, & then stop, the passage, & so on the whole lengh
of the requird pillars, with either an inlet, or an outlet, at the top, or bottom
thereto, each pillar is so constructed, with flanges at the aperture, so as to carry,
the ends of an inner, & an outer double tube, & also to facilitate, the flow of the
water, or other liquids through all the tubes, travelling from side, to side of the
refrigerator. I make a double tube, an inner tube, & an outer tube, as one tube
within the other, the inner tube is longer than the outside tube, or both the ends
of the inner tube protrudes. The ends of these tubes are fixed into the aperture
in the pillars & a current of cold air always passes through the inner tube, which
is open at both ends for that purpose.
I take one, of these double tubes, & put the protruding ends of the inside tube,
through the front apertures in the two pillars placd opposit each other, & they
lodge themselves upon the flanges, going through the apertures, which flanges are
smaller, than the flanges of the front enterance, & the ends of the outside tube, are
lodged, upon the front flanges of the apertures, & I solder or braze the ends of the
double tube, to these flanges of the pillars-or, I may construct the pillars in
section & bolt them together, by rods & screws & put india rubber washers between
the different parts to make them water tight, or use other washers & the inside
tubes, when not soldered, would carry a thread end, & plate with screw nuts thereto,
in this way my improved tubular refrigerator could be easily built to any size &
also could be readly repaired with for any of the parts would be made attachable
& detachable.
Operation-double tubes being joined to the two pillars with the inlet & outlet
pipes & the other parts to received placed in working position, the cold water
enters from the inlet pipe, & rushes into the opening in the pillars & flows between
the space of the inside, & outside tubes, to the other pillar, & rises inside the pillars,
between the opening in the two apertures of the pillars, & flows along the next
double tubes, & so on to the top of the refrigerator, to the outlet pipe, also the
cool air passes through the inner tubes, or pipes perfectly imparting their coolness
to the heated liquids flowing over the tubes either for use of brewers distillers
worts & other fluids. The condensing of steam, the cooling & condensing of spirits
in distillers, or in cooling milk, & the like purposes. Fat, & other like liquids
may be passed through the refrigerator, & the water may flow over the outside
tubes.
I will now proceed to describe, with reference to the accompanying drawings the
manner in which my invention is performed. The same letters of reference
indicate the same parts in the several figures of the drawings.
Fig. 1. represents a front elevation of my refrigerator, showing the tubes, & the
side pillars with their standing feet-& also the trough, at the top, with the inlet
pipe upon the left side, of the refrigerator, are to be seen the open ends of the
inner tubes & five of them, carrying screwed nuts thereon. All the inner tube ends
are open for currents of air to pass through them. Upon each side of the

page_text: refrigerator, are two inner tube ends drawn out, showing how the inner tubes are
placed in position in the refrigerator-india rubber washers are also fixed.
Fig. 2. represents a plan vertical section, which clearly exhibits the construction
of my refrigerator for cooling liquids.
Fig. 3. represents an elevation of an outer & inner tubes, with two blocks of the
pillars, in the left hand block, shew two holes therein, for the rods to go through, to
hold each block of the pillar firmly in position, the right hand block of the pillar
at its top is left open for the water, to rise, or flow, to the tubes above.
Fig. 4. represent a plan of the outer tube.
Fig. 5 represents a section of the outer & the inner tube with the end of inner
tube a thread thereon for to receive the nut.
Fig. 6. represents an elevation of two blocks to help to form the pillars-doted
lines the space for the rods.
Fig. 7. represents two india rubber washers which are placed between the blocks
of the pillars for purpose of helping to keep the refrigerator watertight.
Fig. 8. represents an elevation, of a rod for holding firmly the blocks of the
pillar together.

It is understood, I shall use any kind of metal or material in manufacturing my
improved refrigerator-brass, copper & such like-also I shall form any shape, or
design of tubes, so that the fluids & shall easily pass without sagging.
Having now particularly described & ascertained the nature of my said inven-
tion, & in what manner the same is to be performed I declare that what I
claim, is
1st. I claim a new, or improved method, & apparatus for cooling liquids, by the
admission of a current of air through an inner tube, as set forth & described in
Figures 1. & 2. of the drawings.
2nd. I claim an improved refrigerator with inner tubes for the purpose described
& illustrated.
3rd. I claim a double tube, for a refrigerator, as illustrated in Figures 3. & 5.
