Complete Specification Accepted 10th Aug., 188
I, KATE RACHEL KILBOURN, of 14, Rue de La Trémoille, Paris, in the French
Republic, do hereby declare the nature of my invention to be as follows:-
My Invention relates to a method of generating heated atmospheric air, and
it consists in the several steps which will be more fully hereinafter described.
The essential feature of my method consists in forcing air into a cylinder or
receptacle, there retaining it under pressure, and subjecting it to the action of rapidly
moving frictional appliances, by which it shall become heated to any required degree,
then conveying it to suitable storage tanks or reservoirs, and from thence to the
place or places where it is to be used.
The object of my invention is to provide heat, through the medium of the air,
for heating buildings and for mechanical and other purposes.
In the accompanying drawing, forming a part of this specification, I have illustrated
one of the many ways of carrying this principle into effect, wherein like letters
of reference indicate similar parts, and in which a diagrammatic view of a plant partly
in plan and partly in sectional elevation is shown.
'
A. indicates any suitable and well known form of engine, and B. an air compressor.
Connected with the air compressor B. by a suitable conduit C. is an air-tight
cylinder D. within which is situated an open ended cylinder E. of somewhat less
diameter and length than the cylinder D., and so mounted therein as to leave a narrow
annular space between the cylinders and passages at their ends.

escape through the same. The portion of shaft F. lying within the cylinders is
provided with spirally arranged beaters or blades a., and the portion extending

the engine A. is applied by means of the belt G.
The compressor B. is provided with suitable inlet and outlet passages and valves,
and where the conduit C. connects with the cylinder D. is placed an inwardly opening
valve c. and in said conduit C. is also situated a check valve c¹ for regulating the
flow of air to the cylinder D. from the said compressor B.

to be used for any of the various purposes to which heated air is applicable.

the cylinder D. by the compressor B. until a predetermined pressure is established,

the air a rapid gyrating movement within the cylinder E., and at the same time
producing a strong current in the direction indicated by the arrows. When the air
bas attained a sufficiently high temperature by friction in this cylinder, the
thermostatic valve d. is opened and air allowed to escape through the conduit H. to
the storage tank I. At this period of the operation, the compressor B. is again put
in motion, and the action of the apparatus becomes continuous. The heated air under
pressure can be taken directly from the frictional heating cylinder and conveyed to
the place or places to which it is to be applied for any suitable purpose, thus dispensing
with all storage vessels and reservoirs.
It is obvious that any form of cylinder, valves, compressor, as well as motive power
could be substituted for those shown and described without in the least departing
from the nature and principle of my invention.

page_text: An Improved Method of Generating Heated Air.
1, KATE RACHEL KILBOURN, of 14, Rue de La Trémoille, Paris, in the French
Republic, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
My Invention relates to a method of generating heated atmospheric air, and
it consists in the several steps which will be more fully hereinafter described.
The essential feature of my method consists in forcing air into a cylinder or
receptacle, there retaining it under pressure, and subjecting it to the action of rapidly
moving frictional appliances, by which it shall become heated.to any required degree,
then conveying it to suitable storage tanks or reservoirs, and from thence to the place
or places where it is to be used.
The object of my invention is to provide heat, through the medium of the air, for
heating buildings and for mechanical. and other purposes.
In the accompanying drawing, forming a part of this specification, I have
illustrated one of the many ways of carrying this principle into effect, wherein like
letters of reference indicate similar parts, and in which a diagrammatic view of
a plant partly in plan and partly in sectional elevation is shown.
A. indicates any suitable and well known form of engine, and B. an air compressor.
Connected with the air compressor B. by a suitable conduit C. is an air-tight
cylinder D. within which is situated an open ended cylinder E. of somewhat less
diameter and length than the cylinder D., and so mounted therein as to leave a narrow
annular space between the cylinders and passages at their ends.
F. indicates a shaft so boxed or journaled in the cylinder-heads that no air can
escape through the same. The portion of shaft F. lying within the cylinders is
provided with spirally arranged beaters or blades a., and the portion extending
beyond one of the cylinder heads has fast thereon a pulley b., to which power from the
engine A. is applied by means of the belt G.
The compressor B. is provided with suitable inlet and outlet passages and valves,
and where the conduit C. connects with the cylinder D. is placed an inwardly opening
valve c. and in said conduit C. is also situated a check valve c' for regulating the flow
of air to the cylinder D. from the said compressor B.
d. indicates a valve which controls the outlet from the cylinder D., and is actuated
by the expansion and contraction of a rod e., to which it is attached, and which
is securely fastened to the cylinder D. This valve d. opens into a conduit H. leading
to a storage tank I., which is provided with suitable inlet and outlet valves and
a safety valve J. From the tank I., the heated air may be taken to different points,
to be used for any of the various purposes to which heated air is applicable.
The operation and several steps of my method are as follows: Air is forced into the
cylinder D. by the compressor B. until a predetermined pressure is established, when
its further introduction to cylinder D. is stopped by the cut off valve c¹ in the
conduit C. By means of the belt G., the shaft F. is caused to revolve rapidly, giving

page_text: the air a rapid gyrating movement within the cylinder E., and at the same time
producing a strong current in the direction indicated by the arrows. When the air
has attained a sufficiently high temperature by friction in this cylinder, the
thermostatic valve d. is opened and air allowed to escape through the conduit H.
to the storage tank I. At this period of the operation, the compressor B. is again put
in motion, and the action of the apparatus becomes continuous. The heated air under
pressure can be taken directly from the frictional heating cylinder and conveyed
to the place or places to which it is to be applied for any suitable purpose, thus
dispensing with all storage vessels and reservoirs.
It is obvious that any form of cylinder, valves, compressor, as well as motive power
could be substituted for those shown and described without in the least departing from
the nature and principle of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1.-The herein described method of generating heat, which consists in forcing air
into a receptacle, there retaining it under pressure and subjecting it to frictional
mechanical appliances until the required degree of heat is attained, substantially
as described.
2. The herein described method of generating heat, which consists in forcing air
into a suitable receptacle and there retaining it under pressure and subjecting it to
frictional mechanical appliances until a required degree of heat is attained, and then
conveying the same to a reservoir or receiver, from which it may be distributed
as may be necessary, substantially as described.
