PROVISIONAL SPECIFICATION.
Improvements connected with Thermometers for Ascertaining
Temperatures of Liquor in Mash Tuns, Vats, and other
Vessels.
I, CHARLIE WILLIAM HUON BULLARD, of The Anchor Brewery, Norwich, in
the County of Norfolk, Brewer, do hereby declare the nature of this invention to
be as follows:-
:--
The invention has for its object improvements connected with thermometers to
enable the temperature of liquor to be readily ascertained at various heights of the
same in brewer's and such like mash tuns, vats and other vessels.
For this purpose 1 attach the thermometer to one end of a cord or other
suspender, and I form in or attach to such suspender at desired heights of the same,
loops or eyes by which the thermometer can be suspended at different levels in the
liquor; in connection with such thermometer and suspending means, employ
a tube finely perforated throughout and closed at the lower end by a removable
plug or stopper of preferably conical form; on the upper end of this tube I fix or
form a hook, and I also attach thereto suitable holding and suspending means.
The thermometer is passed into the interior of the perforated tube and suspended
therein at the desired level by means of the eyes or loops of the suspender and the
hook at the upper end of the perforated tube, which latter is immersed in the liquor
till its lower end is just clear of the bottom of the mash tun, vat or other vessel
the said tube with the thermometer therein is then swung to and fro, when the
liquor will pass freely into the interior of the same through the perforations and
there act on the thermometer; the latter is then drawn up to ascertain the
temperature of the liquor at a particular level in the mash tun, vat or other vessel.
When the temperature of the liquor at one level has been ascertained the
thermometer may be suspended in the perforated tube at other heights and the
temperature of the liquor at other levels ascertained in like manner.
;
By making fine perforations in the tube any comparatively large solid particles
are prevented from entering the same. The upper end of the cord or suspender
may be provided with a ring, washer, disc or other supporter, which may rest on
It will be evident that other means of
the upper end of the perforated tube.
suspending the thermometer at different heights in the perforated tube may be used
without departing from the peculiar character of my invention.
The interior of the perforated tube can be readily cleaned after removal of the
plug or stopper from the lower end thereof.

Improvements connected with Thermometers for Ascertaining
Temperatures of Liquor in Mash Tuns, Vats, and other
Vessels.
I, CHARLIE WILLIAM HUON BULLARD, of The Anchor Brewery, Norwich, in
the County of Norfolk, Brewer, 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 invention has for its object improvements connected with thermometers to
enable the temperature of liquor to be readily ascertained at various heights of the
same in brewers' and such like mash tuns, vats and other vessels.
My invention is illustrated in the accompanying drawings, in which :-
Fig. 1 is an elevation of a brewers' or such like thermometer fitted with
suspending means according to my invention.
Fig. 2 is an elevation and Fig. 3 is a vertical section of a perforated tube within
which I suspend such thermometer.
Fig. 4 is a perspective view of a fitting to be attached to the lid of a mash tân,
vat or other vessel through which the thermometer is to be passed.
Fig. 5 is a front elevation, Fig. 6 is a side elevation and Fig. 7 is a vertical
section, of a fitting to be attached to the side of the mash tun, vat or other vessel
when it is desired to pass the perforated tube at an angle through said side, and
Fig. 8 is a sectional view of a mash tun or other like vessel showing the
perforated tube and thermometer passed through the side of the mash tun or other
like vessel.
In all the figures like parts are indicated by similar letters of reference.
a is the thermometer, which is enclosed in a case having an open front 61
to enable the height of the mercury to be read, slots 62 to afford access of the liquor
to the thermometer bulb, and an india-rubber foot 3 to prevent shock to and
breakage of the thermometer should the latter be allowed to fall suddenly. Such
case has also, according to my invention, attached thereto, one end of a cord cor
other suspender, which is provided at desired distances with suspending loops, eyes
or rings e, which may be fixed thereto as shown or may be formed therein or fixed
thereto in any other convenient way, and by which the thermometer can be
suspended at different levels in the liquor as hereinafter described.
In connection with such thermometer and suspending means I employ a tube d,
tinely perforated throughout and closed at the lower end by a removable plug
or stopper of preferably conical form; on the upper end of this tube d I fix or
form a hook d, and I also attach thereto suitable holding and suspending means
consisting of a loop d³ by which it may be hung up when not in use or held when
the thermometer is used in an open mash tun or other vessel. The thermometer is
pussed into the interior of the perforated tube d and suspended therein at the
desired level by means of the eyes, loops or rings c' of the suspending cord cand
the hook d² at the upper end of the perforated tube d, which latter is immersed in
the liquor till its lower end is just clear of the bottom of the mash tun or other
vessel;
the said tube d, with the thermometer therein, when used in an open
vessel, is then swung to and fro, when the liquor will pass freely into the interior
of the same through the perforations and there act on the thermometer; the latter
is then drawn up to ascertain the temperature of the liquor at a particular level in
the mash tun or other vessel. When the temperature of the liquor at one level has
been ascertained, the thermometer may be suspended in the perforated tube at.
other heights and the temperature of the liquor at other levels ascertained in like
manter. The upper end of the cord or suspender e is preferably provided with a

page_text: dise c², or it may be a ring, washer or other supporter, which when the thermometer
is let down into the tube d the full length of the cord c or other suspender, rests on
the
up; er end of the perforated tube d. By making fine perforations in the tube d
any comparatively large solid particles are prevented from entering the same.
It will be evident that other means of suspending the thermometer at different
heights in the perforated tube d may be used without departing from the peculiar
character of my invention. The interior of the perforated tube d can be readily
cleansed after removal of the plug or stopper d¹ from the lower end thereof.
When the thermometer and tube d are applied to a covered mash tun or other
vessel and passed through a hole in the cover thereof, I preferably furnish such
hole with a fitting in the form of a flanged socket such as that represented at Fig. 4,
the flange e of which is screwed to the cover whilst the socket e passes through the
cover, a plug or stopper e² being attached by a chain e³ to an eye e fixed to the
flange e; thus the tube d with the thermometer therein can be passed through
the socket e' into the liquor and when withdrawn therefrom the plug or stopper e²
can be placed in the socket e' to close the same.
When the thermometer and tube d are passed through a hole in the side of the
mash tun or other vessel I preferably furnish such hole with a fitting such as that
represented at Figs. 5, 6, 7 and 8, the flange e of which is screwed to the side of
the mash tun or other vessel whilst the socket e¹ is inclined to and external of said
Hange e. In this case the stopper is shown provided with a screw thread
which can be screwed into a corresponding thread in the upper end of the
socket e¹.
In both forms of flanged socket a hook e is fixed to the flange e so that when the
thermometer and perforated tube are passed through the socket e', the chain e³ can
also be hooked on to the hook e to hold the plug or stopper e² in a fixed position.
The details of the fittings shown at Figs. 4 to 7 may however be varied.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be perforined, I declare that what I
claim is :-
1. The improvements connected with thermometers for ascertaining temperatures
of liquor in mash tuns, vats and other vessels, substantially as herein shown and
described.
2. The combination with a thermometer, of a cord or other suspending means, a
perforated tube for containing the said thermometer, and means for enabling the
suspending means and consequently the thermometer to be held at various heights
within the perforated tube, substantially as herein shown and described and for the
purpose stated.
