We, THOMAS WARSOP of Coniston Engineer, and ARTHUR SAMUEL WARSOP of
76 Queen's Walk, Nottingham Engineer do hereby declare the nature of our said
invention for AN IMPROVED METHOD OF CLEANING & PURIFYING CARPETS OR
OTHER FABRICS, AND APPARATUS THEREFOR 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 an improved method of cleaning and purifying Carpets
or other Fabrics, and to the apparatus required to perform this.
For this purpose we cause a powerful. current of compressed air, divided either
into a number of small jets, or one or more extended jets or sheets of air; to be
thrown onto the Carpet or other Fabric to be cleansed and purified; in such a.
manner, that the air is forced completely through the interstices of the Carpet
or other Fabric; and thereby carries with it the dust or other impurities that may.
be in the Carpet, into a receptacle made to receive them; and from which it is
drawn away by a flue, fan, or other means.
The Carpet or Fabric during the operation is drawn by a roller or other suitable-
means slowly across a table or frame; in the surface of which, and projecting slightly.
above it, a wire gauze or perforated roller revolves over which the Carpet. passes,
while being cleaned; the curved surface of the roller opens temporarily the
interstices of the Carpet; and more freely allows the dust and impurities to be,
forced out by a powerful current or currents of compressed air from the supply
pipe and nozzles or slots placed immediately over this roller; or drum; and so.
arranged that the full width of the fabric passing over the drum is exposed to the
air current.
The dust and impurities are drawn away from the drum by a fan, flue, or other
means.

Or, as an alternative plan, we dispense with the perforated drum before
mentioned, and pass the Carpet over a simple space or slot in the table covered
with wire gauze or netting; & in some cases we give a longitudinal reciprocating,

distribute the air currents over the Fabrics; and in other cases we have a second
pipe alongside the other, with the nozzles in this second pipe arranged to come
between or cover the spaces of the first pipe.
In some cases we use disinfecting or other powders, to be forced through the
Carpets or Fabrics along with the compressed air by suitable means; or in place
of compressed air we use other gases.
And in order that our Invention may be fully understood and readily carried
out & into effect, we will proceed to describe the accompanying sheet of drawings,
reference being had to the letters marked thereon.
Figure 1 is a side elevation of the Carpet cleaning machine, with two rows of
nozzles for the compressed att fixed in two pipes running side by side. Fig. 2 is
an end transverse sectional view through the line 1, 2, Fig. 1.
Figure 3 is a side elevation of another arrangement of the machine, with one
supply pipe carrying the air nozzles; and to which a reciprocating motion can be
imparted. Fig. 4 is an end transverse sectional view through the line 3-4, Fig. 3.
Similar letters refer to similar parts throughout the several views.
In these views A is the frame of the machine carrying the necessary rollers,
drum, &c, in suitable bearings; also the table T, in the centre of which is a space
or slot in which turns the wire gauze or perforated drum or roller B, supported by
shaft C. G is the main supply pipe, conveying compressed air to the several
branch pipes G₁ G³ & G³, and thence to the small nozzles L. L; which are so
formed as to emit each a minute jet of compressed air at their lower extremities.
Each of the pipes G' G³ & G³ is fitted with a stop cock, and arranged preferably as
shewn; so that one or more of the section pipes carrying the nozzles may be shut
off as desired, to suit the width of the carpets to be cleaned.
E&E are rollers or guide runners, under which the carpets pass to and
from the drum B; and their height from the table T is regulated by the hand
wheel and screw F & Fl. D & D* are rollers upon which the carpets are
alternately rolled and unrolled during the operation, by the handle S.
R represents the Carpet or other Fabric to be operated upon.
H is the trough
or flue into which the dust and impurities are forced from the Carpets, and from
whence it is drawn away by suitable means.
Ķ is a movable shield or cover over the nozzle pipe G' G* & G³ to keep the dust
from flying upwards.
The operation of the machine is simply as follows:-the Carpet or other Fabric
to be cleaned is passed from the roll D* under the guide roller E¹, over the
drum B; where it is thoroughly cleansed and purified by compressed air passing
transversely through it, from the nozzles L. L; as it is slowly passed under them,
by being rolled on to the roll D, by the handle S. After the Carpet has been
wound onto the roll D from D*; if found necessary the Carpet can be wound back
again onto D*; after having previously shut off the pipes G₁- & 3 and opened
pipes G; the nozzles of which come in between those of pipes G¹ * & *, and
thus cleanse the intermediate spaces in the Carpet which these latter may not have
covered.
In the machine shewn in Figs. 3 & 4, there is only one set of pipes G³ G³ & G³
carrying the air nozzles; but these pipes are capable of a horizontal reciprocating
motion in the bearings A¹, by means of the rod M, & eccentric U, driven by the
driving pulley N; which also may be made to revolve the roller D* by the
pullies N¹ & Nº, worm P, & worm wheels Q, as shewn; also the roller D by similar
means.
The reciprocating action of the nozzles in G¹ G & G³ causes the air jets to be
more evenly distributed over the Carpet passing under them.
We have described two arrangements of machines to effect the cleaning of
carpets by our improved method; but any other suitable kind of machine may be
employed to effect the same end by our improved method.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
--
1. The use and application of one or more currents of compressed air, of sufficient
force or pressure, as to pass through the interstices of Carpets or other Fabrics, in
such a manner, that the dust and other impurities are carried from the Carpets or
Fabrics along with the compressed air; and the Carpets or other Fabrics are
cleansed and purified thereby; as set forth, and substantially as shown and
described herein before.
2. The particular arrangements and construction of the machinery or apparatus
shewn in Figures 1-2-3 & 4 of the annexed drawings; whereby Carpets or other
Fabrics can be cleaned and purified; as set forth, and substantially as shewn and
herein before described.
