I TIMOTHY JOSEPH CANTY of Clonakilty in the County of Cork Ireland,.
Brewery Manager, do hereby declare the nature of my said invention for "AN
IMPROVED SELF-ACTING APPARATUS FOR HEATING AND CIRCULATING WORTS IN
BREWERS MASH TUNS," to be as follows:-
The object of my invention is the construction and arrangement of a simple and
effective apparatus for gradually heating and circulating worts in brewers mash
tuns, so that the worts may be heated to any degree of temperature. To this end
my apparatus is constructed as follows;-I take a copper of any convenient size or
shape for heating the worts, and encase it, either partially, preferably lower half of
it, or the whole of it with a shell or jacket leaving a space between the shell and the
copper, which space is connected with a steam boiler by a suitable pipe provided
with a stop cock or valve, so that steam at any desired pressure may be admitted
to the jacket outside the copper so as to heat the worts to any desired temperature.
Where it is not convenient to heat the copper by steam, fire or gas may be used for
the purpose.
The top of the heating copper is connected to the mash tun by a pipe in any
convenient manner, so that the worts may be discharged either into the top of the
mash tun, or through the sparger. The bottom of the mash tun is connected with
the heating copper by a suitable pipe trapped with a non-return valve, or other
convenient form of trap; so that the worts may circulate only in one direction
viz, from the mash tun to the copper, and from the copper to the mash tun and
so on continuously. It will be seen that as the worts are continually circulating
round between the mash tun and the heating copper, the temperature of the worts
will be gradually raised until a sufficiently high degree of temperature has been
obtained.
Where the mash tun and heating copper cannot be conveniently placed and
arranged, it may be necessary to fit a small pump somewhere between the copper
and the mash tun to assist the circulation of the worts.

I TIMOTHY JOSEPH CANTY of Clonakilty in the County of Cork, Ireland
Brewery Manager 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 invention is the construction and arrangement of a simple and
effective apparatus for gradually heating and circulating worts in brewers mash
tuns, so that the worts may be heated to any degree of temperature.
To attain this end I construct an apparatus as illustrated in the accompanying
drawing, throughout the figures of which similar parts are marked with like letters
of reference. Figure 1, is a view showing the general arrangement of my apparatus
and Figure 2 an enlarged sectional view of the heater.
Referring to these figures I take a copper or heater A of any convenient size or
shape for heating the worts, and encase some portion of it, preferably the lower
half, with a shell or jacket B leaving a space between the shell and the copper,
which space is connected with a steam boiler by a pipe C provided in some
convenient position with a stop-cock, so that the steam may be admitted to the
jacketted space outside the copper at any desired pressure to heat the worts to
the necessary temperature and also with an outlet pipe C to allow the steam
to escape. Where it is not convenient to heat the copper by steam, any other
heating agency such as fire or gas may be used for the purpose.
The top of the heating copper A is connected to the mash tun X by a pipe D,
through which the worts pass from the heating copper to the mash tun either
directly or through the sparger E as illustrated by Figure 1. The bottom of the
mash tun X is connected with the heating copper A by a pipe F which is fitted with
a stop-cock and a non return valve f₁ the former to shut off the circulation of
the worts when desired, and the latter to ensure the worts circulating in one
direction only, viz:-from the mash tun to the copper through the pipe F and from
the copper to the mash tun through the pipe D and so on continuously.-The
pipe F is also trapped and provided with a waste pipe cock f at some convenient
part of its length. I sometimes find with large mash tuns it is convenient to have
more than one outlet to the heater in which case I carry any convenient number
of pipes from the bottom of the mash tun and connect them all to one common
pipe before the stop cock fis-reached.
It will be seen that as the worts is heated it will commence to circulate through
the mash tun and heating copper and thus its temperature is gradually raised to
any desired degree.
When the heating copper cannot be conveniently placed and arranged with
respect to the mash tun I fit a small pump somewhere in the length of the pipe D
between the heating copper and the mash tun to assist or start the circulation of
the worts.

page_text: 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:-
First The apparatus for heating and circulating worts in brewers mash tuns as
hereinbefore described and shown.
Second-The combination of the heating copper A, steam jacket B, delivery
pipe D, mash tun X and return pipe F all combined arranged and operating as and
for the purpose herein before set forth.
