page_text: I LEWIS HART GUINNESS of Greville Place Kilburn in the County of Middlesex
Brewer, do hereby declare the nature of my said invention to be as follows:-
This invention relates to the construction of a protecting case used for a
Registering Thermometer in order that it may be inserted in and withdrawn from
closed or open vessels containing liquids or semi-liquids used more particularly in
Breweries or other businesses in such a manner that the Thermometer may be
totally submerged in the liquid or semi-liquid and the protecting case then with-
drawn so as to expose the Thermometer when wholly submerged to the full action
of the heat and thus obtain the accurate reading of the temperature at any
required depth and after such exposure to replace the protecting covering for the
purpose of again withdrawing the Thermometer from the liquid thus avoiding the
risk of breaking the glass of the Thermometer.
For this purpose the Thermometer is fitted in a metal case protected externally
by another close fitting moveable case constructed so that the Thermometer with
its external case may be inserted in the liquid or semi-liquid in the mash tun or
other vessel and as soon as the required depth is reached by withdrawing the
external case the whole surface of the Thermometer may be exposed to the action
of the heat. The external case may then be replaced and the Thermometer
withdrawn.
The metal cases are preferably jointed at the end containing the Thermometer
to facilitate insertion in semi-liquids and this end is so arranged as to screw on or
off in order that the Thermometer may be removed and the case taken in pieces
and cleaned.
In making this case I prefer constructing the receptacle for the Thermometer in
the most suitable manner for the reception of "Cassella's Registering Thermometer"
but it can be made in any suitable manner to allow any Thermometer to be
inserted.

I LEWIS HART GUINNESS of Greville Place Kilburn in the County of Middlesex,
Brewer, 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:-
This Invention relates to the construction of cases for Thermometers used more
particularly in Breweries or similar businesses.
The object of this Invention is to allow a Thermometer to be wholly submerged
in a fluid, or in the case of brewing in the "mash" protected by a sliding casing so
that when submerged a part of the case can be withdrawn to allow the thermometer
to be acted on directly by the material in which it is submerged and the case can
be closed again when it is necessary to withdraw the thermometer for examination,
thus avoiding the danger of damaging the thermometer.
This case consists of an inner tube Fig. 2 having a suitable receptacle at one end
for the insertion of a thermometer. The end containing a thermometer is shown
full size in Fig. 6, "a" being the thermometer "6" the tube containing the
thermometer "c" the cap which is screwed off to permit of the thermometer being
introduced into the receptacle. The tube is partly cut away at "d" so as to allow
the mercury or other substance in the thermometer to be exposed to the liquid or
material in which it is submerged. It has also a part cut away for the purpose of
reading the degrees of temperature registered by the index "e."
This inner tube is surrounded by another tube shown at Fig. 1 sliding in such a
manner that the end containing the Thermometer can either be pushed beyond the
end of the outer tube to expose the thermometer, as shown in Figs. 3 and 6 or
drawn in so as to be wholly covered by it. To facilitate the sliding of the outer
tube over the inner one, the inner tube has guiding enlargements. These enlarge-
ments are shown at "f" Fig. 2 and in full size with outer tube in section in
Figs. 4 and 5.
The handle and outer tube in section fitting on inner tube are shown full size in
Fig. 4-Fig. 3 shows the outer tube slipped over the inner tube and drawn back
so as to expose the thermometer to the liquid or material the temperature of which
is required to be ascertain.
The length of the slide of the outer thermometer tube can be regulated
by stops.
I prefer making the end of the inner tube pointed to facilitate insertion in the
"mash or other similar substances.

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 arrangement of sliding case and inner tube substantially as above
described and for the purpose above stated.
Second The combination of a registering thermometer and thermometer case
substantially as above described and operating substantially in manner above
stated.
