Coolers Used in the Manufacture of Beer.
I, ROBERT RANGER, of 1 Stone Street, Maidstone, Kent, Engineer do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to draw off the top surface of wort from the cooler,
such draw off being followed by an apparatus acting automatically as the level is
lowered.
For the purpose of my invention, I fit a valve to act as an exit to a wort cooler
used in the process of brewing, said valve working like a telescope. Directly over
the valve is a wheel with a double groove, in one groove of which a chain is affixed
and is connected at the other end with a float on the surface of the wort. In the
second groove of the double grooved wheel runs a chain connected at one end with
the valve and at the other with a balance weight to counterbalance the weight of valve
and float.
When the float lowers in the cooler the balance weight is raised and being con-
nected by its chain with the valve, the valve itself naturally lowers correspondingly
in its gland. This automatic action enables the surface wort which is bright and
thoroughly aerated to be drawn off without disturbing the sediment or deposit in the.
cooler.

page_text: I ROBERT RANGER of No. 1 Stone Street, Maidstone, Kent, Engineer do hereby
declare the nature of my said 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 this invention is to draw off the top surface of wort from the cooler,
such draw off being followed by an apparatus acting automatically as the level is
lowered.
For the purpose of my invention I fit a valve to act as an exit to a wort cooler
used in the process of brewing, said valve working like a telescope.
Directly over the valve is a wheel with a double groove, in one groove of which a
chain is affixed and is connected at the other end with a float on the surface of the
wort. In the second groove of the double grooved wheel runs a chain connected at
one end with the valve and at the other with a balance weight to counterbalance the
weight of valve and float.
My invention is clearly shown in the annexed drawings Figures 1 and 2 side and
end views respectively.
A is the valve composed of a short length of piping fitted liquid tight in the exit
pipe B affixed to the bottom of the wort cooler C.
The upper end of the valve A is, preferably, corrugated to admit of perfect aeration
to the clear wort flowing over the top edge. This valve A is secured by a cross head D
to a chain E by a screw F and pinch nuts G G, for adjustment, the chain passing
over a wheel H and having a weight I suspended counterbalancing the valve A and
the float J, this being connected by a chain K riding over a pulley L and terminating
with the wheel H which is preferably a double grooved wheel as seen at Figure 2 or
two grooved wheels connected, said wheel H and pulley L being attached to the top
cross beam M by brackets N. N.
The apparatus above described may be applied to the cooler direct or to a shallow
well or trough attached to a cooler and instead of the upper part of the valve A being
funnel shaped and corrugated as indicated it may be of any other desired shape and
have a plain top edge.
The action is as follows. When the float lowers in the cooler the balance weight is
raised and being connected by its chain with the valve, the valve itself naturally lowers
correspondingly in its gland. This automatic action enables the surface wort which
is bright and thoroughly aerated to be drawn off without disturbing the sediment or
deposit in the cooler.

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 :-
1. The combination of the several parts hereinbefore described acting automatically
for regulating the surface flow of wort from coolers used in the manufacture of beer
substantially as indicated by the annexed drawings.
2. In connection with an apparatus by which the surface flow of wort can be auto-
matically drawn off the double grooved wheel H or its equivalent for the
described.
