General Idea.
A constant cause
of calefaction
whether lamp or
culinary fire,
constantly sufficient
to maintain
in the Tepidarium
(Whether
Air Chamber or
Balneum) a degree
of temperature
above the degree
required.
The function of
the Regulator
being to reduce
the temperature to
the degree required.
The heat, where
above the degree
required acting
on the Regulator
causes it to open
a Valve, which
lets out a part
of the air or
of the Tepidarium
and lets in cold
air or water in
the room of it.

Regulating Valve. 1. The Valve a flate plate, lying upon an aperture, and closing it by its weight. A tube closed at the bottom containing a fluidopen at top containing mercury or water with a cylindrical cork floating on it. A wire ??? through the cork in the centre of it, rises, and pushes up the valve: the heat causing the fluid in the tube to expand, and the expansion causing it to rise and raise the cork with it 2. The Valve a circular or plate semicircular plate turning on a hinge in the circumference of the circle or in the axis of the semicircle. The valve may be opended by the wire rising against it as above, or by a lever, the power of which is increased by an influx of mercury not towards the extremity of the lever
