Improvements in Condensers, Refrigerators, and the like.
I, THOMAS KINLOCH BARCLAY, of Battlefield Avenue, Langside, Glasgow, in
the County of Lanark, North Britain, Metal Merchant, 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 relates to improvements in condensers, refrigerators and the like
and has for its object to effect rapid and economical cooling of vapours, worts,
chemicals and such like.
Figure 1 is a sectional elevation of a well known form of a condenser fitted with
my improvements.
Figure 2 is a sectional plan of the same.
Figure 3, drawn to an enlarged scale, is a section of a condenser tube and plate
showing a spiral within the tube in accordance with my invention. The spirals
may consist of lengths of helical, twisted or equivalently formed strips of metal or
other material.
Figure 4 is a part sectional elevation, drawn to a similar enlarged scale, of a
corrugated tube which may be used instead of a plain tube and which is fitted with
a spiral in accordance with my invention.
Instead of the steam or vapour passing direct through the cooling tubes a from
the inlet b, it is checked by the spirals c with which the tubes are provided in
accordance with my invention. The steam or vapour thus gets broken up and is
rapidly and effectively acted upon by the cold water or other cooling medium
surrounding the outside of the tubes. The resulting distilled water or other
product enters the reservoir or storage tank or receptacle at a lower temperature
than when tubes are used without the said spirals.
The spirals may be single, double or triple bladed or any other formation of
spirals or their equivalent may be used. They may be of steel, brass, copper,
rolled block-tin, aluminium, glass or of any other suitable material. They may be
in one length or in short lengths. When of short lengths they may be connected
together with a connecting rod passed through their centre or by any other suitable
means.
In Figure 1 represents the receptacle for collecting the distilled products, to
be drawn off by the outlet e. f is an ordinary form of aerater used in the case of
sea water distillation. The cooling medium may enter at g and flow out again
at h.
My invention may be employed for all kinds of condensing and refrigerating
purposes where the cooling is effected by cold water, carbonic acid gas, ether and
the like, such as for refrigerating worts, chemicals and such like. The tubes and
spirals can be readily cleaned by simply drawing out the spirals.
As a modification the water or other cooling medium may be passed through the
tubes fitted with the said spirals instead of outside the tubes, in which case the
worts, chemicals and such like may be passed round or outside of the tubes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
In condensers, refrigerators and such like, the employment of spirals or like

described and shown in the accompanying drawings.
