Improvements in Carpet Beating Machines.
I, JOHN CHAPMAN of No. 1 Arthur Street, Aldrington in the County of Sussex,
Steam Carpet Cleaner do hereby declare the nature of this invention to be as
follows:-
The objects of my invention are-
1st. An improved sloping bed over which the carpet passes while being beaten.
2nd. An improved method of fastening the rubber belting or other beaters to the
revolving cylinder.
3rd. An improved form of cylinder mounted on the main driving shaft.
At the present time the sloping bed of carpet beating machines is made of wire
spring, leather, rubber or cotton stretched across a frame and sloping towards the
centre and bottom of the machine. These various materials used are fastened to
the framework of the bed and are immovable except so far as to have the necessary
amount of flexibility to prevent a carpet being damaged when struck with the
beaters. It is on account of the bed being fixed that it is so quickly worn out,
owing to the constant rubbing of the carpets on the lower edge of the bed. When
this part is worn out the bed is of no more use until provided with new straps of
leather etc. or of wire springs thus entailing considerable outlay.
In carrying out my invention I make use of the ordinary erection as at present;
through the length of which and at a suitable height from the floor is a driving
shaft worked by means of a pulley and strap outside the erection. On this driving
shaft I place a hollow cylinder, preferably in three equal lengths having four
flanges at right angles. These three lengths are fastened to the driving shaft by
means of screws, bolts or keys or in any other suitable manner.
At each end of
the three lengths of the flanged cylinder there is a coupling and when mounted on
the driving shaft the centre couplings fit close together and are fastened by means
of bolts.
On the side of each of the flanges I place a piece of flat steel plate the
same length as that of the flange. I bolt the two together leaving however a small
space between them. In this space I place one end of the rubber belting or other
form of beater. The beaters are of such a length that when the loose ends are
worn they can be drawn forward thus saving having to replace with new ones
They are not placed close together but a small space is allowed between each;
when sufficient have been placed in position I tighten up the bolts until the whole
of the beaters are securely fastened.
The improved sloping bed on which the carpet is beaten consists of two rollers
(having suitable bearings) one roller being placed close to the slot or opening
through which the carpet is passed into the machine; and the other one nearer
the base and further from the side of the machine. From roller to roller I have
at short distances from each other a series of endless straps made of rubber belting

drawn into the machine by the action of the beaters the straps of the bed move
slowly round thus preventing an unnecessary amount of wear on one part of
the bed.

I, JOHN CHAPMAN of No. 1 Arthur Street, Aldrington in the County of Sussex,
Steam Carpet Cleaner 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 carpet beating machines and has for its objects,-
1st. An improved sloping bed over which the carpet passes while being beaten.
2nd. An improved method of fastening the rubber belting or other beaters to the
revolving cylinder.
3rd. An improved form of cylinder mounted on the main driving shaft, and
4tb. An improved brush attachment.
The carpet beating machines as at present constructed have many disadvantages
which it is my intention to remove. For instance, the sloping bed usually consists
of leather, rubber, wire spring or cotton and is stretched across a wooden frame-
work sloping towards the bottom of the machine. The material used is fastened
to the framework and is immovable except that it has the necessary amount of
flexibility to prevent any damage being caused to a carpet by the beaters. The
bed being a fixture accounts for it being worn out so quickly at the lower edge
which renders it of no more use until provided with new straps of leather, rubber,
cotton or wire springs thus entailing considerable outlay. The brush attachment
at present in use has also certain disadvantages inasmuch as it is often placed on
the outside of the machine and when working throws the dust upon the operator.
It also prevents free access of the carpets into the machine aud impedes their
withdrawal. The system of raising and lowering the brush is also imperfect and
has been improved upon in my invention.
In order that my invention may be more readily understood reference is made
to the accompanying drawings, in which
Fig. 1, is a plan of my improved carpet beating machine showing however only
a portion of the sloping bed, beaters and brush to prevent confusion.
Fig. 2 is a longitudinal section.
Fig. 3 is a transverse section.
Fig. 4 is an end view of the machine.
Fig. 5 is an enlarged transverse section of part of the machine showing a carpet
being passed through the same.
Fig. 6 is an enlarged end view of the machine showing the arrangement for
raising and lowering the brush.
Fig. 7 is an enlarged plan of the flanged cylinder and beaters,
Fig. 8 is a section of the same.
Fig. 9 is an enlarged detail showing the method of supporting the brush shaft ;
and Fig. 10 is a sectional plate of the same on A. B. Fig. 9.
The same letters of reference apply in all the figures.
In carrying out my invention I make use of an ordinary erection similar to that
at present in use, through the length of which and at a suitable height from the floor
is a driving shaft, a, worked by means of fast and loose pulleys and straps outside
the machine. Mounted on this driving shaft I have à cylinder c cast with four
flanges d at right angles. The cylinder is preferably made in three equal lengths
although in some machines two and in others a larger number might be used with
advantage. These three equal lengths are fastened to the driving shaft by means
of screws, bolts or keys or in any other suitable manner. At each end of the three
lengths of the flanged cylinder I provide a coupling e and when mounted on the driving
shaft the centre couplings fit close together and are fastened by means of bolts f
On the side of each of the Hanges I place a piece of flat steel plate g the same

arranged so that a small space is left between each and when sufficient have been
placed in position the bolts (which are placed in the spaces between the beaters)
are tightened until they are securely fastened.
The improved sloping bed over which the carpet passes while being beaten
consists preferably of two rollers k fitted through the length of the machine having.
suitable bearings; one of them being placed close to the slot or opening m through
which the carpet is passed into the machine and the other nearer the base and
further from the side of the apparatus. From roller to roller I have at short
distances from each other a series of endless straps n made of rubber belting or
any other suitable and substantial material having sufficient flexibility to prevent
the carpet being in any way injured by the strokes of the beaters. As the carpet is
being drawn into the machine by the action of the beaters the straps of the bed
move slowly round thus giving an equal amount of wear to all the bed.
In connecting the brush attachment I use a driving, shaft o similar to that
previously described being also arranged with fast and loose pulley wheels p.
Upon this shaft is mounted in one, two or more equal parts a circular broom r
made of bass or other material and connected by means of set screws.
The brush shaft o at its ends is fitted into a curved groove p¹ and slotted plate p²
(extending downwards to about the top of the sloping bed) at each end of the
provided at the lower
machine and is carried by or supported upon upright bars s
ends with racks or cogs s¹ which gear with a circular or semi-circular cogge:
wheel t also at each end of the machine and connected together by means of a
small shaft or rod u. These upright bars are so made that the upper parts form
the journals for carrying or supporting the brush shaft.
The cogged wheel t has a suitable arm or lever v which when raised or depressed

also provide for securing the same at any desired height above the bed n by means
of a rack into which the lever can be fixed. When the brush is not in use it
is carried by the cogged wheel t which is prevented from moving by the lever
being placed in the rack &.
The groove p¹ and slotted plate p² which the ends of the brush shaft o traver-e
are curved at the upper portions to form segments of a circle so that the driving
belt used for driving the brush has not to be removed from the pulleys when the
brush is being raised or lowered.

one and at the same time bringing into operation the cross driving belt provided
at one end of the machine. This cross belt reverses the action of the brush which
not only assists in withdrawing the carpet from the apparatus but also removes

understood that the brush attachment can be so regulated as to admit any thickness
of carpet by means of the lever before mentioned and if desired can be dispensed
with altogether by raising it several inches above the bed. By using the brush
55 attachment in addition to the beaters the carpet is not only beaten but brushed and
saves considerable time it being possible to complete at one operation what
formerly had to be done by manual labour after the beating was finished.

page_text: 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;
First. An improved form of cylinder having four flanges and provided with flat
steel plates bolted to the same, between the flauges and plates being fastened the
beaters, as above described and illustrated in the accompanying drawings.
Second. An improved sloping bed of endless straps arranged on rollers as above
described and illustrated in the accompanying drawings.
Third. An improved brush attachment together with the apparatus for raising
and lowering the same as above described and illustrated in the accompanying
drawings.
