page_text: I, EDWARD HAMMERTON, of 17 Royal Terrace, Upton Park, East Ham, in the
County of Essex, Draper, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the cleaning of carpets and has for its object to perform
the operation more quickly and efficiently than heretofore and especially to prevent
damage to the carpet. For this purpose my invention consists in the process and
in the novel construction of the parts of the apparatus, and in their arrangement
and combination, as hereinafter described.
The carpet is carried along over a feed roller onto a perforated platform where
it is sprinkled with water and beaten by a set of canes which strike the carpet
and are lifted therefrom without any motion along the surface of the carpet and
thus cause no tearing of the pile; from the platform the carpet passes over a
second roller of comparatively small diameter, whereby the pile of the carpet is
more or less opened so that the brushes applied to the carpet at this point, are
enabled to more effectually remove the dust. After passing the brushes, the carpet
leaves the apparatus. The apparatus may be constructed as follows: The feed
roller may be provided with pins or other means for ensuring on equal and sure
feed of the carpet to be beaten onto the platform. This latter may be fixed or
may be revolvable on a pair of rollers, in which case its motion corresponds to
that of the feed roller. The platform is perforated and a trough is arranged
below for the reception of the dust beaten out of the carpet. The beating is
performed by a set of rods or canes preferably malacca canes, which are arranged
parallel to each other and clamped at their rear ends to a beam, to which a rocking
motion is given by suitable gear. The canes will thus rise and fall so as to strike
the carpet as it lies on the platform. For the sprinkling of the carpet with water
I arrange a water pipe preferably parallel to the feed roller and provided with jets or
perforations, by which the carpet may be uniformly sprinkled as it lies on the
platform. I do not however confine myself to one pipe but may use
more if
necessary and may also perform the sprinkling at any stage of the operation.

page_text: At the rear end of the platform is arranged a roller over which the carpet passes
downwards, or in the case of a revolving platform the carpet passes over the end
of the latter. In front of this roller or end of the platform, a number of brushes
are arranged on a revolving shaft this latter shaft revolves with double the
velocity (or thereabouts) of the platform, and I may arrange thereon a continuous
circular brush, but I prefer to use flat brushes, arranged symmetrically on each
side of their shaft and preferably arranged at a slight angle across the latter;
means should also be arranged to compensate for the wear of the brushes, this
I may do by moving the whole shaft forward with its bearings, or by causing the
shaft to revolve excentrically in its bearings, and varying the degree of this
eccentricity or, by providing means for extending the brushes radially from the
shaft or otherwise. The carpet passes from the brushes downwards and leaves
the machine preferably beneath the said dust trough. I may, if necessary, use a
fan or other exhaust or an excavator such as an archimedian screw, to remove
the dust from the trough, or I may arrange a water sprinkler in the trough,
removing the dust afterwards through doors in the sides of the trough.

page_text: I, EDWARD HAMMERTON of 17 Royal Terrace Upton Park East Ham in the County
of Essex, Draper, 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 the
following statement:-
This invention relates to the cleaning or beating of carpets and has for its object to
perform the operation more quickly and efficiently than heretofore, and especially to
prevent damage to the carpet.
For this purpose my invention consists in the process and in the novel construction
of the parts of the apparatus and in their arrangement and combination as hereinafter
described.
The carpet is carried along over a feed roller onto a perforated platform where it is
sprinkled with water and beaten by a set of canes which strike the carpet and are
lifted therefrom without any motion along the surface of the carpet, and thus cause no
tearing of the pile or surface of the carpet. From the platform the carpet passes over
a second roller of comparatively small diameter, in such a manner that the pile of
the carpet is opened or separated so that brushes applied to the carpet at this part are
enabled to more effectually remove the dust from out of the carpet. After passing
the brushes, the carpet leaves the machine.
Referring to the accompanying Drawings which show a machine capable of
performing these operations.
Fig. 1 is a plan view of the principal portions of the machine, the roof or enclosing
chamber being removed.
Fig. 2 is a side elevation with side of said enclosing chamber removed.
Fig. 3 is a front elevation also with a portion of the front of the enclosing chamber
removed, and with part of the dust trough also removed.
Fig. 4 is a detail view on an enlarged scale of the feed roller platform and brushes.
A represents the carpet before cleaning. B the carpet as it issues from the
machine after undergoing the operations described. C is the feed roller which may
be provided with pins a (Fig. 1) for feeding the carpet onto the platform D. The
platform D is perforated and may be either stationary or travelling, in which latter
case it is in the form of an endless apron travelling over the rollers E and b. c is a
pulley on the roller C and d a pulley on the roller E, the said pulleys being geared
together by belt or cord e-The carpet passes down over the roller E as indicated in
Fig. 2 whether the platform D be moving or stationary Fare canes adapted to strike
the carpet upon the platform D-G is a rocking beam to which said canes are fixed,
said beam being rocked by crank and pitman g. operated by one of the wheels or
pulleys of the machine-H are dust troughs under the platform D, the same having
doors for the removal of the dust-J is the sprinkler for sprinkling water over the
carpet, it consists of a perforated pipe extending across the machine. Such sprinklers
may likewise be arranged in the dust troughs and other parts of the machine where

page_text: desirable. K are the brushes by which the carpet is brushed as it passes over the
roller E, these brushes are flat as shown, and are mounted in pairs no the shaft L so
as to extend in diametrically opposite directions, they are preferably fixed at an angle
across the shaft as shown in Fig. 1, and the shaft is made displaceable from the centre
of the wheel M which supports and drives said shaft, said wheel being journalled
centrally, and preferably toothed so that it may be operated by a tooth wheel N on the
roller E. The opposite end of the shaft L may be carried excentrically upon or by
the disc or wheel O, the latter journalled centrally.
The carpet passes from the brushes K aforesaid down through the passage P
contrived on the one side by the wall of the dust trough and on the other by match-
boarding or other partition separating the said passage from the interior of the
chamber containing the brushes and other apparatus; the cleaned carpet leaving the
machine at B. Qis the chamber of matchboarding or other suitable material con-
taining the beforementioned parts-The roof thereof may be sloping as shown in
Fig. 2, being of a height sufficient to give the necessary space for the sweep of the
canes F-R is the space for the carpet to enter the machine.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is ;-
The herein described process of carpet cleaning, consisting in the beating of said
carpet in the opening of the pile thereof and in the brushing of said pile and carpet
when opened substantially as set forth.
2) The combination of a platform D, a series of canes F adapted to strike said
platform and he lifted therefrom-Roller E and brushes K substantially as and for
the purpose set forth.
3) The combination with brushes K of shaft L supporting said brushes, and
excentrically journalled, the amount of said excentricity being adjustable substantially
as and for the purpose set forth.
Dated this 11th day of October 1887.
EDWARD HAMMERTON.
