page_text: LETTERS PATENT to John Townsend Trench, of Kenmare, in the County of
Kerry, Ireland, Land Agent, for the Invention of "IMPROVEMENTS IN APPA-
RATUS FOR WARMING GREENHOUSES AND OTHER BUILDINGS AND FOR BURNING
LIME"
Sealed the 16th June 1876, and dated the 7th January 1876.
PROVISIONAL SPECIFICATION left by the said John Townsend Trench at
the Office of the Commissioners of Patents on the 7th January 1876.
JOHN TOWNSEND TRENCH, of Kenmare, in the County of Kerry, Ireland, Land
Agent. "IMPROVEMENTS IN APPARATUS FOR WARMING GREENHOUSES AND OTHER
BUILDINGS AND FOR BURNING LIME."
This Invention has for its object improvements in apparatus for warming green-
houses, Turkish baths, churches, and other buildings, and for burning lime.
For warming greenhouses and other buildings by means of heat generated in the
process of burning lime, I place an air box, pipe, or flue around or over an ordinary
lime kiln. A pipe admits the outside air into this box or flue, and another pipe
conducts the air, after it has been heated by passing through the air box or flue,
into the building to be warmed. At the top of the building I provide an opening
or exit pipe to create a constant current from the air box which is heated by the
kiln. I cause the air to enter the greenhouse or building through a box, in which
pans or trays of water are placed to moisten the warm air. A valve is provided to
regulate the air current, and there may also be air conducting pipes, and also a
passage controlled by a valve, by which the outer cold air may, when desired, be
admitted to mix with the warm air before it enters the building.
Where hot water pipes are employed to warm buildings, I enclose them for a
distance between the boiler and the building in an exterior pipe or flue of larger
size, and through this pipe or flue I admit air into the building. The warm air
before entering the building may be moistened, as already described.

size, and through this pipe or flue I admit air into the building. The warm air
before entering the building may be moistened, as already described.
In order that my said Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section of a lime kiln, having combined with it apparatus
for supplying warm air to a greenhouse or other building.
A, A, A, air pipe or flue of fire-clay or other material that goes round the inside
of the lime kiln, and the air running through this pipe gets heated by the heat of
the lime kiln, and passes on into the greenhouse, but before doing so the air
traverses an air box with a water pan in it to make the hot air damp. This air box
is shown to a larger scale in section at Figure 2. The circular box over the kiln is
for catching this top heat in same way. The air box over the kiln may have
zig-zag fines through it to get the benefit of all the heat. I put thermometers into
these pipes.
I also employ a similar damping box to moisten air which has been rendered hot
by passing through pipes or flues enclosing hot water pipes before such hot air is
allowed to enter the greenhouse or other building to be warmed.
What I claim is,-
The combination with a lime kiln of pipes or boxes, which become heated by the
fire in the kiln, and through which air is passed on its way to a greenhouse or other
building which is warmed thereby.
I also claim the arrangement of the air box for moistening the hot dry air from
the kiln, or air rendered hot by passing through a pipe or flue surrounding hot
water pipes, as described.
In witness whereof; I, the said John Townsend Trench, have hereunto set my
hand and seal, this 6th day of July, in the year of our Lord One thousand
