I, THOMAS HAIGH, of Liverpool, in the County of Lancaster, Common
Brewer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN COOLERS FOR THE USE OF BREWERS AND OTHERS," to be as follows,
(that is to say):-
This Invention relates to certain arrangement of apparatus for the cooling
of worts and other liquids, and parts of which are so constructed and arranged
that portions thereof can be readily removed for cleaning and repairing the
same.
A refrigerator constructed according to this Invention consists of a number
of flattened tubes of copper or other metal arranged horizontally and parallel
to each other. These flattened tubes may be closed at the ends by metal
diaphragms or by a longitudinal plate faced with india-rubber or other
suitable elastic material, which extends across the whole length of the ends of
each end of the pipes, and are held together by means of screwed rods and
nuts, or in any other convenient manner; these vertically flattened pipes or
tubes are connected together at alternate ends by means of a union joint and

page_text: at the reverse ends by means of screwed studs and a union nut resembling
the ordinary union pipe joint. The parallel pipes with their vertical end or
side pieces are fitted into an open trough which is formed with a slightly raised
platform in the centre, upon which the pipes are laid, and which are of tho
same length, so that the side and end pieces may abut against the side of the
platform, and thus by the aid of india-rubber or other elastic material will
form a water-tight joint when screwed up against the sides of the platform
and ends of the pipes, thus forming an open-topped vessel for containing the
horizontal parallel flattened tubes or pipes through which the water or other
cooling fluid circulates. The cooling water is admitted into the first of the
series of vertical flat-sided tubes, from whence it passes through the union
pipe joint into the next compartment at the reverse end of the tube from
which it entered, when it passes to the reverse end of the tube and out
through the union joint into the next tube, and so on, thus passing through
the whole series of tubes in an horizontal zig-zag direction, after which it is
allowed to escape. The tops of the parallel tubes are formed with longitudinal
feathers which extend the whole length from side plate to side plate, being
water-tight, the ends of the said feathers being in close contact with the side
plates. The worts or other liquid to be cooled is first introduced between tho
'first end plate and the first vertical sided tube until it rises to the top of the
tube, when it escapes through an opening formed near the end of the feather
piece on to the other side of the tube, and comes in contact with the side of
the next tube until it rises sufficiently high to escape through an opening in
the feather piece on the reverse end from that which it entered in between
the reverse side of the second tube and the rear side of the third tube, and
so on, the liquid to be cooled travelling in an horizontal zig-zag direction
through between the whole series of tubes, after which it is allowed to run off
into the tun. Space is allowed between tho end plates and sides of the
trough to contain any liquid that may escape from between the pipes and
side plates. By this arrangement it will be observed that the tubes and
side or end plates may be removed from the trough for the purpose of
cleaning, and one or any number of the vertical sided tubes or water
chambers may be removed, as they are all alike and fitted together by the
joints and unions having the same thread throughout. In place of allowing
the worts or other liquid to be cooled to pass from between one side of the
tubes to the next by means of the openings in the vertical feather piece
passages may be formed beneath the ends of the pipes or through the ends of
the pipes or round the ends of the pipes. To insure strength in the flattened
pipes to bear the pressure and prevent the same being put out of shape by

page_text: the pressure or other cause it is proposed to insert a number of short pipes
which extend across the interior of the flattened tubes and through which is
passed a short bolt or rivet clenched on each end, similar to the stays in a
locomotive boiler.
