PROVISIONAL SPECIFICATION.
Improved Means for Indicating Heat in Buildings from Distant
Points.
I. SAMUEL BRIGGS, of the Firm S. Briggs & Co., Burton Copper Works,
Burton-on-Trent, Brewers Engineers, do hereby declare the nature of this
invention, which has been communicated to me from abroad by Jean Schneider,
of 25 Rue de la Rivière, Brussels, Belgium, Constructing Engineer, to be as
follows:-
This invention has for object, the detection and indication of increase heat in a
malting house during the malting operation.
The invention is essentially composed of a mercurial thermometer in connection
with an electric appliance capable of being set for indicating when the temperature
of the malting house is becoming excessive, and attendance required; a sound, or
other signal at a distance being in circuit for drawing attention to the fact that
the heat has increased to the limit for which the apparatus is adjusted.
To carry the invention into practice, a mercurial thermometer is provided with
side bulbs in which conducting wires are hermetically affixed at different heights of
the scale, this being visible for ordinary inspection. The conducting wires are led
to a dial, where they are secured to terminals over the face plates, of which a hand
lever can be moved, and temporarily fixed each plate being marked with a degree
to correspond with that or those on the scale, so that when the mercury in the
thermometer tube rises by the increase of heat in the building, the circuit becomes
completed, and a sound given.
The indicator, and sound producer may be in the same building, or in separate
buildings for indicating, on the spot, or at a distance, or at both, simultaneously
that the heat is excessive.
The invention is specially adapted for malting houses, but is applicable for all
purposes, and for all trades where a determined heat is desired.

COMPLETE SPECIFICATION.
Improved Means for Indicating Heat in Buildings from Distant
Points.
I, Samuel BRIGGS, of the Firm S. Briggs and Co., Burton Copper Works,
Burton-on-Trent, Brewer's Engineer, do hereby declare the nature of this invention,
which has been communicated to me from abroad by Jean Schneider of
25 Rue de la Rivière, Brussels, Belgium, Constructing Engineer, and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
This invention has for object, the detection and indication of increase heat in a
malting house during the malting operation.
The invention is essentially composed of a mercurial thermometer in connection
with an electric appliance capable of being set for indicating when the temperature
of the malting house is becoming excessive and attendance required, a sound or

page_text: other signal at a distance being in circuit for drawing attention to the fact that
the heat has increased to the limit for which the apparatus is adjusted.
The invention is clearly represented in the annexed drawings.
Figure 1 is a sectional elevation of a building, say, a malting house with the
mercurial thermometers having electrical wires attached in the upper room, the
wires passing down to the bell, dial and batteries in the lower room.
Figure 2 is a diagram on a larger scale of the complete apparatus in connection
and showing the construction of the mercurial thermometers and the indicating
dial plate.
To carry the invention into practice, a mercurial thermometer (two being shown)
A is provided with side bulbs B in which conducting wires C are hermetically
affixed at different heighths of the scale this being visible for ordinary inspection.
The conducting wires are led to a dial D where they are secured to terminals E
over the face plates of which a hand lever F can be moved and temporarily fixed,
each plate being marked with a degree to correspond with that or those on the
scale, so that when the mercury in the thermometer tube A rises by the increase
of heat in the building, the circuit becomes completed and a sound given by an
electric bell G affixed to the dial, or at any other part of a building.
The indicator A and sound producer G may be in the same building, or in
separate buildings for indicating on the spot, or at a distance, or at both,
simultaneously that the heat is excessive.
The thermometer also has hermetically connected with it another wire H for
-connection with the dial D by the screw I, other wires J, K, L connecting the dial
with the bell and battery.
In the drawings, Figure 2, the handle is shown as in connection with a terminal
indicating 70 degrees, this representing the limit of the degree of heat which can
be sustained in the room in which the thermometer is situated, and the thermometer
indicates between 5 and 60 degrees of heat, now when the mercury rises in the
thermometer by the heat in the room to 70 degrees, an electric circuit is established
through the wires M, N, and contact piece Q from the battery through the
handle F, terminal E, corresponding wire C, mercury in thermometer, wire H,
screw I, wire J to bell G thence to wire K, contact piece P by wire L, or vice versa
according to the arrangement of the battery, thus causing the bell G to ring and
draw attention to the fact that the heat in the room has reached its desired limit
and must be reduced to about the necessary degree by ventilation, or other suitable
means, thus it will be understood that at whatever terminal E the handle F is put
in contact with the electric circuit will be completed when the mercury rises in the
thermometer to the degree equivalent to the number on the terminal.
The invention is specially adapted for malting houses but is applicable for all
purposes and for all trades where a determined heat is desired.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
1. The improved means for indicating heat in buildings from distant points as
described and substantially as shown on the annexed drawings.
2. The combination of one or more thermometers having wires hermetically
sealed therein, a dial having terminals, and a handle or handles, a bell and battery,
the whole being in electrical communication, as and for the purposes described and
substantially arranged as illustrated by the annexed drawings.
