page_text: LETTERS PATENT to William Taylor, of Nursling, in the County of
Southampton, Gentleman, and William Dakin Grimshaw, of the Town
and County of the Town of Southampton, Engineer, for the Invention of
"REGULATING THE ADMISSION OF NATURAL ATMOSPHERIC AIR, AND EDUCTION
OF RAREFIED AIR OR GASSES FROM HOTHOUSES, OR ANY OTHER PLACE OR
PREMISES, AND FOR SUPPORTING A REQUIRED TEMPERATURE".
PROVISIONAL SPECIFICATION left by the said William Taylor and
William Dakin Grimshaw at the Office of the Commissioners of Patents,
with their Petition, on the 29th December 1858.
WILLIAM TAYLOR, of Nursling, in the County of Southampton, Gentleman,
and WILLIAM DAKIN GRIMSHAW, of the Town and County of the Town of
Southampton, Engineer, do hereby declare the nature of the said Invention for
REGULATING THE ADMISSION OF NATURAL ATMOSPHERIC AIR, AND EDUCTION OF
RAREFIED AIR OR GASSES FROM HOTHOUSES, OR ANY OTHER PLACE OR PREMISES, AND
FOR SUPPORTING A REQUIRED TEMPERATURE:" the said apparatus is actuated
by pressure of steam, water, gasses, or any other fluid, or by the temperature
of the atmosphere; the said apparatus is also applicable to indicate the
pressure of steam in steam boilers, and allow the steam to escape when it
gets above the required pressure, to be as follows —

page_text: A, a flexible eliptic or other shaped reservoir of bladder, india-rubber, or
other flexible material for containing a required quantity of atmospheric air
at 32 or less degrees of temperature, and by being exposed to any tempe-
rature exceeding that, causing the atmosphere contained in the reservoir to
expand and give motion to the peston and rod B, from thence transmitting
motion through the lever C to any required form of ventilation or damper D,
for indicating the degrees of temperature by which either damper, regulator,
or ventilator is regulated, as shown by the pointer D round the index E. F

mounting for supporting the lever, index, &c., &c.; H, a moveable ball or
weight by which the ventilator or damper may be regulated to any degree
of temperature that may be required; I, connecting rod from lever C to
ventilator K. This apparatus can also be used as a fire alarm, being placed
in any room, building, ship's hold, or any other place, and by the temperature
being raised to any given degree, fire by spontaneous combustion, or any
other cause, can be ascertained by the apparatus ringing a bell, gong, or
any other alarm.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Taylor and William Dakin Grimshaw in the Great
Seal Patent Office on the 25th June 1859.

them, the said Willam Taylor and William Dakin Grimshaw, Her special
licence that they, the said William Taylor and William Dakin Grimshaw,
executors, administrators, and assigns, or such others as they, the said William

was
NOW KNOW YE, that we, the said William Taylor and William Dakin
Grimshaw, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
A self-acting ventilator or damper regulator for regulating the admission of
natural atmospheric air,and eduction of rarefied air or gasses from hothonses,
or any other place, and for supporting a required temperature. The said
apparatus is actuated by pressure of steam, water, gas, or any other fluid, or
by the temperature of the atmosphere; the said apparatus by being attached
to a valve, is also applicable to indicate the pressure of steam in steam boilers,
and allow the steam to escape should it supersede the required pressure;
also a thermometer, to indicate the heat in ship's hold, ricks, or any other
places, and as a common thermometer. The apparatus can also be used as a
fire alarum by being placed in rooms, ship's holds, ricks, &c., and by the
temperature being brought to any required degree, fire by spontaneous com-
bustion, or any other cause, can be ascertained by the apparatus causing to
ring a bell, or any other alarum.
The plan filed herewith, shewsA, flexible elipticorotherwiseshapedreservoir,
of metal, bladder, india-rubber, or other suitable material, for containing a
required quantity of atmospheric air of thirty-two or less degrees of tempe-
rature, and by being exposed to any temperature below or exceeding that
standard, causes the atmosphere contained in the reservoir either to contract
or expand accordingly, and gives motion to the piston and rod B; from
thence it transmits motion through the lever C to any required form of venti-
lator or damper for indicating the degrees of temperature by which either
damper, regulator, or ventilator is worked, as shewn by the movements of the
pointer D on the index E. F represents the cylinder, of wire gauze, or any

page_text: other suitable material, consisting of a diaphragm, or any other reservoir for
containing the atmosphere, for preventing the horizontal expansion, and
allowing the rarefied atmosphere to act on the reservo r. G, the bracket and
mounting for supporting the lever index plate, gearing. &c., &c.; H, a move-
able ball or weight, by which the ventilator or damper may be regulated to
any degree of temperature that may be required; I, connecting rod from
lever C to ventilator K; L, a fire-lock or alarm, communicating with the lever
C, to be discharged at any temperature by setting the small pointer in the
quadrant M to the required temperature corresponding with the dial E, and
by this arrangement a bell of any size could be made ring, or a gun of any
size can be fired by the variation of four degrees of temperature. By placing
the atmospheric cylinder or reservoir in the hold of a ship, or in deep shafts
of mines, and by simply attaching the connecting wire to the index P, the
temperature where the cylinder or reservoir is, can be ascertained (no matter
how deep the vessel's hold or shaft may be) on the deck of the vessel, or on
the surface of the earth. N, the flexible diaphragm, which rises and falls
by the expansion and contraction of the atmospheric air contained in the
cylinder, and gives motion to the piston and rod B; O, spiral spring, to
assist the downward motion, and prevent the diaphragm from working
above the proper range.
In witness whereof, we have hereunto set our hands and seals, this
Twenty-third day of June in the year our Lord One thousand eight
hundred and fifty-nine.
