Improvements in Carpet or other Fabric Cleansing Methods
and Apparatus.
BENJAMIN KERR ANDERSON Carpet Cleaning Works Proprietor Westland
Row Dublin and JOHN BATEY Engineer 47 Heytesbury Street Dublin do hereby
declare the nature of this invention to be as follows:-
This invention relates to carpet or other fabric cleansing methods and apparatus.
in which air is the cleansing medium and is applicable to all apparatus in which
compressed air is used as a medium for eliminating dust dirt insects and for general
disinfecting purposes.
The object of this invention is to provide a means for heating drying and
augumenting the volume of air after being compressed whereby all impurities such
as insects or disease germs are disseminated and destroyed and the air thoroughly
dried or superheated and greatly increased in volume by the means to be hereafter
more particularly described and further the object being to dry up the moisture in
the fabric operated upon thereby facilitating the process of cleansing.
In a carpet or other fabric cleansing apparatus in which air is the medium in
which the air after being compressed is forced into a reservoir or receiver from
which it is conveyed by suitable pipe or pipes through a highly heated stove the
part of pipe or pipes in stove being very much enlarged thereby permitting the air
to expand into a very much larger volume and being brought under the influence
of the highly heated pipe or pipes it is raised to a high temperature sufficient to
destroy all insect life or disease germs-the said enlargement of pipe or pipes is a
continuation of the conveying pipes which after passing through the stove is
continued on to the cleansing machine and on to the fabric to be cleansed thereby
the moisture is absorbed and dryed up by the heated air whilst the pressure
assisted by the increased volume drives out the dust and dirt which is drawn away
by an exhausting fan or other means it being obvious that the effect of increasing
the volume of air whilst under the same pressure is equal to an increased amount
of motive power and compressing efficiency. It being one of the essential con-
ditions of this invention that the air is heated after it has left the reservoir or
receiver and on its way to the fabric to be cleansed, whereby the air as it passes
through the stove is dealt with in detail and increased volume.
The stove in which the air is heated may be of a special construction in which the
pipe,or pipes are surrounded by fire clay settings and deflectors whereby the flame
and heat are deflected back on to the pipe or pipes before passing away to the
chimney but by preference one large tube several areas larger than the conducting
pipe one end of which connected to the inlet side of stove the other being free to
expand through the other side.
Having now particularly described the nature of our invention for improvements
in carpet or other fabric cleansing methods and apparatus we claim for the same
substantially as herein before set forth.

Improvements in Carpet or other Fabric Oleansing Methods
and Apparatus.
We BENJAMIN KERR ANDERSON. Carpet Cleaning Works Proprietor Westland
Row Dublin and JOHN BATEY Engineer 47 Heytesbury Street Dublin 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:—
This invention relates to carpet or other fabric cleansing methods and apparatus
in which air is the cleansing medium and is applicable to all apparatus in which
compressed air is used as a medium for eliminating dust dirt insects and for general
disinfecting purposes.
The object of this invention is to provide a means for heating drying and
augumenting the volume of air after being compressed whereby all impurities such
as insects or disease germs are disseminated or destroyed and the air thoroughly
dried or superheated and greatly increased in volume by the means to be hereafter
more particularly described and further the object being to dry up the moisture in
the fabric operated upon thereby facilitating the process of cleansing.
In a carpet or other fabric cleansing apparatus in which air is the medium in
which the air after being compressed is forced into a reservoir or receiver from
which it is conveyed by suitable pipe or pipes through a highly heated stove the
part of pipe or pipes in stove being very much enlarged thereby permitting the air
to expand into a very much larger volume and being brought under the influence of
the highly heated pipe or pipes it is raised to a high temperature sufficient to
destroy all insect life or disease germs the said enlargement of pipe or pipes is a
continuation of the conveying pipes which after passing through the stove is
continued on to the cleansing machine and on to the fabric to be cleansed thereby
the moisture is absorbed and dried up by the heated air whilst the pressure assisted
by the increased volume drives out the dust and dirt which is drawn away by an
exhausting fan or other means it being obvious that the effect of increasing the
volume of air whilst under the same pressure is equal to an increased amount of
motive power and compressing efficiency. It being one of the essential conditions.
of this invention that the air is heated after it has left the reservoir or receiver and
on its way to the fabric to be cleansed whereby the air as it passes through the
stove is dealt with in detail and increased volume.
The stove in which the air is heated may be of a special construction in which
the pipe or pipes are surrounded by fire clay settings and deflectors whereby the
flame and heat are deflected back on to the pipe or pipes before passing away to
the chimney but by preference one large tube several areas larger than the
conducting pipe one end of which is connected to the inlet side of stove the other
being free to expand through the other side.
The stove in which the air is heated may be of a special construction, and by
preference is made as follows as suitable for dealing with compressed air passing
through a conducting pipe of 3 inches diameter. The body of stove may be made
of cast iron plates bolted together at the corners, rectangular in. form the height
being sufficient to allow for a fire grate and fuel and the diameter of tube crossing
above same--which may be twice the diameter of conducting pipe-one end of
said tube by preference is flanged at one end and is bolted against one side of
stove, to this the conducting pipe is attached the other end of tube is long enough
to pass through a hole in the opposite side of stove, and is not connected thereto-
but is attached to a continuation of the conducting pipe on the outlet side-above
the tube an arch of fire resisting material, such as fire clay tiles or bricks, deflects
the heat back on to the top of tube, before passing away to the chimney or
outlet--the inside of stove is also lined with a similar fire resisting material-the

page_text: stove as described is raised above the ground by legs or supports placed under-
neath it is obvious that any other class of stove in which a pipe or pipes is
brought under the influence of strong heat would effect the purpose set out.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. The method hereinto set forth of highly heating air in connection with carpet
or other fabric cleansing apparatus in which air under pressure is the cleansing
medium.
2.-Heating air after being compressed and whilst on its way to the fabric to be
cleansed in connection with carpet or other fabric cleansing apparatus.
3. The combination of a stove surrounding a part of the outlet pipe from a
reservoir or receiver containing air under pressure said stove being heated either
by fuel or gas in connection with carpet or other fabric cleansing apparatus.
4. Ejecting warm or hot air on to fabrics to be cleansed for the purpose of
absorbing or drying up the moisture in same in connection with carpet or other
fabric cleansing apparatus.
5.-Passing compressed air through a highly heated stove for the purpose of
destroying all impurities such as insects or disease germs and for generally
disinfecting purposes in connection with carpet or other fabric cleansing apparatus.
6. Highly heating compressed air on its way through outlet pipe to increase its
volume in connection with carpet or other fabric cleansing apparatus.
