Improvements in or relating to the Cleaning and Purifying of
Carpets, Furs, and other like Materials.
We, GEORGE WIGLEY of Marlborough House, Elm Avenue, Nottingham, Silk
Merchant, and THOMAS WARSOP, of Coniston via Ambleside, Engineer, do hereby
declare the nature of this invention to be as follows:-
This Invention has for its object improvements in and relating to the cleaning and
purifying of carpets, furs, and other like materials.
To effect this purpose, we store a supply of air under pressure in a strong and
suitable air storage reservoir; into which, by suitable means, we pump air under
pressure; and by the same means, maintain as far as possible a constant supply of air
under about the same pressure, whenever air is taken away by the carpet cleaning
machine described below.
This carpetcleaning machine consists ofahexagonalor other suitable shaped casing,
of a length a little longer than the carpet fur or other fabric to be cleaned; and is
provided with a hinged door on each side, to allow the carpet or other material to pass
in and out. Inside this casing, and running the full length of it, we have an air pipe
connected in one or more places with a pipe from the air reservoir, so as to convey air
to this longitudinal air pipe.
At regular intervals in this air pipe, we fixblowing nozzles; having at their outward
extremities very fine elongated apertures or slits, which cause the air issuing there-
from to be emitted in a thin sheet of compressed air. These nozzles are so fixed in
the air pipe, that these sheets of air abut one another longitudinally, and form one long
sheet of issuing compressed air; under which we cause the carpet, furs, or other
material requiring to be cleaned, to pass slowly; either over a revolving roller, or by
hand. The carpet, fabric, fur, or other material so passing under this sheet current of
air, has all dust, dirt and other impurities-- contained in it-blown away by the force
of the air current issuing from these elongated nozzles; and from the air storage
reservoir in connection also therewith. The loose dust from the carpets is drawn
away from the machine by the usual well known means.

Improvements in or relating to the Cleaning and Purifying of
Carpets, Furs, and other like Materials
We, GEORGE WIGLEY of Marlborough House, Elm Avenue, Nottingham, Silk
Merchant, and THOMAS WARSOr, of Coniston ria Ambleside, Engineer, 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 has for its object improvements in and relating to the cleaning and
purifying of carpets, furs, and other like materials.
To effect this purpose, we store a supply of air under pressure in a strong and
suitable air storage reservoir: into which, by suitable means, we pump air under
pressure; and by the same means, maintain as far as possible a constant supply of air
under about the same pressure, whenever air is taken away by the carpet cleaning
machine. described below.
This carpetcleaning machine consists ofahexagonalor other suitable shaped casing,

page_text: of a length a little longer than the carpet, fur, or other fabric to be cleaned; and is
provided with a hinged door on each side, to allow the carpet or other material to pass
in and out. Inside this casing, and running the full length of it, we have an air pipe
connected in one or more places with a pipe from the air reservoir, so as to convey air
to this longitudinal air pipe.
At regular intervals in this air pipe, we fixblowing nozzles; having at their outward
extremities very fine elongated apertures or slits, which cause the air issuing there-
from to be emitted in a thin sheet of compressed air. These nozzles are so fixed in
the air pipe, that these sheets of air abut one another longitudinally, and form one
long sheet of issuing compressed air; under which we cause the carpet, fur, or other
material requiring to be cleaned, to pass slowly; either over a revolving roller or by
hand. The carpet, fabric, fur or other material so passing under this sheet current of
air, has all dust, dirt and other impurities-contained in it-blown away by the force
of the air current issuing from these elongated nozzles; and from the air storage
reservoir in connection also therewith. The loose dust from the carpets is drawn away
from the machine by the usual well known means.
And in order that the said Invention may be fully understood, we shall now proceed
more particularly to describe the same, and for that purpose shall refer to the several
figures on the annexed sheets of drawings, the same letters of reference indicating
corresponding parts in all the figures.
Figure 1 is a transverse section of our carpet cleaning machine combined with an
air storage reservoir R.
Figure 2 is an elevation-partly in longitudinal section--of the nozzle pipe and
several nozzles of our carpet cleaning machine, to an enlarged scale.
Figure 3 is a transverse section through line 1--2 (Figure 3).
A is the main framing of the machine, carrying the hexagonal-or other suitable
shaped casing B, which is fitted with a hinged door C. D is the nozzle pipe carrying
the blowing nozzles E; the nozzle pipe D being connected with the air storage
reservoir by supply pipe J, fitted with the stop valve K. The roller F, which is pre-
ferably perforated or formed of longitudinal bars is carried in suitable bearings from
the main framing A, as are also the carrying rollers H, and I. The nozzles E have
each a fine slit T formed in their lower end, which is fitted with an adjusting ring N,
for the purpose of varying the dove-tail shape or size of the air jet issuing from the
slits Tas shown by the dotted lines P; if the ring N is lowered the slit T will be
contracted, and the dove-tail air jet l' reduced in width. We prefer to so adjust the
rings N, so that the air jets abut one another-as shown in Figure 2-and form a thin
sheet of compressed air which passes right through or across the pile of the carpet or
other fabric, or across the hairs of the furs, rugs, &c.—all of which are represented
by M in the attached drawings-as it is passing over the side of the roller F. By this
means all dust and other impurities are carried away from the carpet-furs, skins or
otherwise by the air jets from nozzles E, and storage reservoir R. The dust
and air are withdrawn from the casing B by an exhaust fan or other suitable
means.
In some cases, instead of taking the compressed air from the storage reservoir R
through the machine shown in Figure 1,-we attach a flexible pipe L to the reservoir
at one end, and fit the other end with one or more nozzles E, by suitable means; for
the purpose of bringing the air jets to act upon, and clear from dust, cloth of all
descriptions, coats, trousers and other wearing apparel, curtains, dresses, and all kinds
of materials that harbour dust & other kindred impurities. These coats, cloth,
dresses &c. being properly hung up or opened out, so that the whole of their surface
can be played upon by the air jet or jets at the end of flexible pipe L.
The construction of the nozzles E to discharge an air jet in the shape of a dovetail,
can be varied in several ways already known in the construction of gas burners, we
have here only shown one simple way in which it can be done, and the spread of the
dovetail regulated by making the rings higher or lower, longer or shorter. In
some cases we prefer to send the compressed air right through the carpets or other
fabrics.

page_text: Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is—
1. In machines for the purposes mentioned the combination of an air storage
reservoir with a pipe carrying a series of air nozzles arranged to throw a thin sheet
of compressed air across the surface of carpets or other materials, passing over a
roller under these nozzles, substantially as herein before described.
2. In machines for the purposes mentioned the combination of a pipe carrying a
series of nozzles arranged to throw a thin sheet of compressed air on materials passing
under them, with a perforated carrying roller and air storage reservoir, substantially
as herein before described.
3. In machines for the purposes mentioned the combination of an air storage
reservoir with a flexible hose pipe and one or more air nozzles for cleaning clothes
and other kindred materials by compressed air substantially as herein beforedescribed
4. In machines of the kind described, one or more air nozzles having an adjustable
ring or rings at one extremity for varying the spread of the air jet issuing there,
substantially as hereinbefore described.
5. The arrangement and combination of parts hereinbefore described and shewn in
Figures 1 to 3 of the annexed drawings.
