I ALFRED BUSH WILLWAY of St Augustines Parade "The Drawbridge" Bristol,
Engineer do hereby declare the nature of my said invention for
AN IMPROVED
APPARATUS FOR REGULATING TEMPERATURE IN DWELLINGS AND BUILDINGS APPLI-
CABLE ALSO FOR DETERMINING THE FLOW OR PASSAGE OF STEAM, GAS, AIR,
LIQUIDS AND FLUIDS," to be as follows:-
The object of my invention is to construct or arrange an apparatus in such
a manner that the temperature of any gas, fluid, liquid, or of any place can be
reduced increased or maintained at any desired degree according to the adjustment
or set of the apparatus.
The apparatus acts automatically when once set or adjusted, this being effected
by simply setting a pipe, a plug, a valve, or its equivalent, closer to, or farther from
an outlet or passage.
The invention is applicable for determining the heat of rooms of dwellings and
the like; for cabins and other parts of ships; for conservatories, for steam and
other hot closets, for water heaters, for gas-cooking and like stoves, for regulating
the passage of gas, steam, air, or other fluids through pipes, in fact for any and
every apparatus or wherever it can be fitted for the purpose of regulating heat or
temperature.
For the purpose of my invention I attach two discs together at their edges.
These discs are corrugated, preferably, in concentric rings. To the centre of one
dise I purpose affixing a tube, this being in communication with the chamber
between the two discs and has its free end closed. The other disc has a stem, plug,
valve or other appliance fitted on it, which may be passed into a tube to uncover
apertures, to open or to close a passage, more or less, or to open or to close a valve
according to the purpose for which the invention is intended.

page_text: In some cases the apparatus is enclosed in a box or casing and heat on coming
into contact with it causes the air in the chamber to dilate, and expand the discs,
and to thereby actuate the stem, plug, valve, or other appliance attached or other-
wise connected with the discs or of one of them.
The tube referred to as being affixed to one of the discs may be dispensed with
in certain casos.
An Improved Apparatus for Regulating Temperature in Dwellings
and Buildings, Applicable also for Determining the Flow or
Passage of Steam, Gas, Air, Liquids, and Fluids.
I ALFRED BUSH WILLWAY of St Augustine's Parade, "The Drawbridge" Bristol,
Engineer do hereby declare the nature of my 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 my invention is to construct or arrange an apparatus in such
a manner that the temperature of any gas, fluid, liquid or of any place can be
reduced increased or maintained at any desired degree according to the adjustment
or set of the apparatus.
The apparatus acts automatically when once set or adjusted this being effected
by simply setting a pipe, a plug, a valve or its equivalent closer to or farther from
an outlet or passage.
The invention is applicable for determining the heat of rooms, of dwellings and
the like; for cabins and other parts of ships, for conservatories, for steam and other
hot closets, for water heaters, for gas cooking and like stoves, for regulating the
passage of gas, steam air or other fluids through pipes, in fact for any and every
apparatus or wherever it can be fitted for the purpose of regulating heat or
temperature.
For the purpose of my invention which will be understood by reference to the
annexed drawings I attach two discs A, A¹, together at their edges as shown at
Figure 1. These discs A A' are corrugated, preferably in concentric rings and
preferably made of copper or other elastic material.
To the centre of one disc A I purpose affixing a tube B this being in communi-
cation with the chamber C between the two discs A A' and has its free end D

page_text: closed. The other disc A¹ has a stem, plug, valve or other appliance E fitted on it,
which may be passed into a tube F to uncover apertures G, G, to open or to close
a valve according to the purpose for which the apparatus is employed.
The apparatus is preferably enclosed in a box or casing H and heat on coming
into contact with it causes the air in the chamber C formed by the discs A, A¹, to
dilate and expand the said discs and to thereby actuate the stem, plug, valve or
other appliance attached or otherwise connected with the discs or one of them.
The plug or cylindrical piece of metal Ẹ turned true on one face or covered with
asbestos, india rubber or any substance (Figure 2) that is elastic and capable, on
the discs expanding and pressing it against the tube F, of forming there a gas tight
joint or the cylindrical piece or plug E may be screw threaded and provided with
a cap E' (Figure 3) capable of adjustment and setting to the desired height, said
cap E being covered with elastic material if necessary In order that the gas may
not be turned quite out (as a safeguard) as small hole is drilled in the side of tube F
near the bottom as shown.
The tube B referred to as being affixed to one of the discs may be dispensed with
in certain cases as shown in Figure 2 and instead of the heat being regulated by
applying the discs to cause a gas flame to be raised or lowered by the heat of water
or air operating directly on the discs or the box containing them I may convey
heat to the discs by means of steam and employ an arrangement similar to that
shown at Figures 3 and 4.
Figure 4 shows the application of my invention for regulating the heating of
a boiler. I by means of a burner or stove J, steam being conveyed through the
pipe K to actuate the discs A, A1, in the valve chest L and thereby control the
amount of gas passing through the pipes M M to the burner or stove J.
The apparatus regulates the amount of gas passing to the burner at boiling
point of water (that is to say when steam is passed through the chamber or
pipe K. The tube F is adjusted to such a distance from the valve seat or plug E
that when the discs are expanded by the heat from the steam it shall wholly or
partially close the aperture at the bottom of tube F. On steam passing through
the chamber or pipe K the heat expands the air sealed between the discs A A'
which raises the metal plug E and closes the bottom of the tube F this decreasing
or preventing the passage of the gas and reducing the quantity consumed. When
steam is used for determining the temperature at which the gas shall be reduced
it is not necessary to drill a hole in the side of tube F if the heat conveyed
from the steam and the quantity of gas passing in or out at the bottom of the
tube F will balance each other Thus if the gas is checked so that the water from
which the steam is generated loses its heat so that the temperature falls below
boiling point the steam ceases to pass through the chamber or pipe K and the discs
will contract opening the bottom F. At last just enough steain will pass through
the chamber EL to make up for the heat lost by radiation.
Figures 5 and 6 show the application of my invention to a greenhouse or
conservatory, the discs A. A' being used in connection with a sliding vertical
ventilator N.
Figure 7 represents an arrangement adapted to ventilating a room or hall or
ships cabin and consists of a box or case, P to be fixed preferably near the ceiling
or roof (of the room or place to be ventilated) and over the opening, grating or
perforated brick. The case P is open at the bottom for the admission of the heated
atmosphere of the room to the discs A, A1, and is provided with a lid or flap Q
connected by a rod R with one of the discs A¹. When the atmosphere of the room
becomes heated the discs, A, A', are expanded and cause the lid or flap to open
by means of the rod R thus regulating the quantity of air passing out of or into
the room according to the heat of said room automatically.
Figure 8 shows the application of my invention to a circular or window ventilator
the discs A, A¹, being connected therewith by means of a horizontal rod R which
may be of any desired length.

- Figure 9 represents a modification of my invention in which the discs A, A, A¹, A¹,
are provided with a tube B bent or otherwise formed communicating with an air-
tight chamber or cylinder S; said chamber S on being heated causes the air within
itself, the tube B and between the discs A A¹ to expand and thus (the discs A A¹
being preferably made of copper corrugated in concentric rings and consequently
elastic) actuates the discs.
This tube B may itself be modified in any way or it may communicate with any
sealed vessel to which the heat is applied.
Figure 10 represents the invention applied to a cone valve. The valve T is
operated by the discs A. A through the pivotted connecting lever U. In this
manner a small motion of the discs may be made to produce any desired motion of
the valve as will be easily understood.

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
The appliance A A' when in connection with other appliances shown in the
annexed drawings and forming an apparatus for regulating temperature in dwellings
and buildings applicable also for determining the flow or passage of Steam, Gas,
Air, Liquids and Fluids as herein before described.
