The object of the invention is to enable any one or other of a row of chimnies
to be swept whenever desired by means of a weighted brush let down the chimney
without its being necessary for any one to get on to the roof' to place the brush
into the chimney which has to be swept.
For this purpose we erect along the sides of a stack or row of chimnies and at a
short distance above them a pair of horizontal rails for a moveable truck to run on.
Below this truck the weighted brush is carried by means of a chain. At one end
of the row or stack of chimnies an additional chimney or vertical passage is formed

carries the brush passes up between pullies on the truck and is then led downwards
through the above mentioned vertical passage a guide roller or pulley being pro-
vided above the top of this passage for the chain to run over. At the bottom of
the passage the chain is wound on to a roller or barrel the spindle of which has
also mounted loosely upon it another barrel of the same dimensions having a chain
wound around it in the opposite direction-this chain is also led upwards through
the passage and then over a guide pulley at the top to the opposite end of the line
of rails here it is passed round another guide pulley and then back again and is
secured to the truck. Provision is also made for locking the two barrels together
or for unlocking them when required.
Instead of the two barrels being upon the same spindle they might be side by
side on separate spindles and provision made for gearing them together by toothed
wheels or for setting them free one from the other.
When the apparatus is out of use the brush is drawn close up to the bottom of
the truck and the truck is kept above the top of the vertical passage and under a
roof or cover which protects it. When it is required to sweep any one or other of

page_text: the chimnies the two barrels are locked together and the barrels are turned
preferably by a crank bandle upon their spindle in such manner as to unwind the
chain which passes to the brush and to wind up the other chain.
In this way the truck can be caused to travel along the rails and can be brought
over any one or other of the chimnies. When it has been brought into the position
desired the barrels are set free the one from the other and the weighted brush is
then allowed to descend into the chimney over which it has been brought it can
then be moved up and down within the chimney by the chain to which it is
suspended being alternately wound up on to or allowed to unwind from the barrel
to which it is connected.
To prevent the escape of soot from the top of the chimney whilst it is being
swept we employ a disc or cover which rests on the top of the chimney when the
brush descends into it the chain passes loosely through a hole formed through
the centre of this cover.
When the chimney has been swept the chain which carries the brush is wound
up until the cover has been lifted from the top of the chimney and the brush has
been brought close up to the underside of the truck-the two barrels are then
again locked together and by continuing to wind up the chain which carries the
brush the truck can be brought back under its roof or cover. As it is drawn under
this roof or cover it may if desired be made to move past a swinging flap which
when the truck has passed will drop and hang down in front of the truck so as the
more completely to protect it whilst it is out of use.
The soot which is dislodged by the brush when a chimney is being swept falls
down the chimney and in order to prevent the soot from falling into the fireplace
at the bottom we provide a hinged flap by which the passage from the fireplace to
the chimney can at this time be closed and a passage from the bottom of the
chimney be simultaneously opened into a closed chamber or receptacle having a
pan at the bottom in which the soot may be collected and subsequently removed.
The hinged flap might if desired be opened or closed by a chain led up to the
upper room or attic in which the operation of sweeping the chimney is conducted.
The apparatus above described will also be found very serviceable in case of fire
in any of the chimnies as the cover which is above the brush can then be made to
rest upon the top of the chimney and stop all draught through it whilst at the
same time the flap at the bottom of the chimney can be closed and the brush be
passed up and down so as to extinguish the flames.

We, EDWARD WARREN LAY of North End, Hampstead, in the County of
Middlesex, Plate Polishing Machine Manufacturer, and CHRISTIAN CESCINSKY
of 18 Berners Mews, Oxford Street in the said County of Middlesex Cabinet
Manufacturer do hereby declare the nature of our invention for "IMPROVED MEANS
AND APPARATUS TO FACILITATE THE SWEEPING OF CHIMNEYS" and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement :-
The object of the invention is to enable any one or other of a row of chimneys
to be swept whenover desired by means of a weighted brush let down the chimney
without its being necessary for any one to get on to the roof to place the brush
into the chimney which has to be swept.
For this purpose we erect along the sides of a stack or row of chimneys and at a
short distance above them a pair of horizontal rails for a moveable truck to run on :
Below this truck the weighted brush is carried by means of a chain-At one end
of the row or stack of chimneys an additional chimney or vertical passage is formed
leading downwards into a room or attic at the top of the house. The chain which
carries the brush passes up between pulleys on the truck and is then led down-
wards through the above mentioned vertical passage, a guide roller or pulley being
provided above the top of this passage for the chain to run over.
At the bottom of the passage the chain is wound on to a roller or barrel, the
spindle of which has also mounted loosely upon it another barrel of the same
dimensions having a chain wound around it in the opposite direction. This chain
is also led upwards through the passage and then over a guide pulley at the top to
the opposite end of the line of rails-bere it is passed round another guide pulley
and then back again and is secured to the truck. Provision is also made for locking
the two barrels together or for unlocking them when required. Instead of the two
barrels being upon the same spindle they might be side by side on separate spindles
and provision made for gearing them together by toothed wheels or for setting
them free one from the other.
When the apparatus is out of use the brush is drawn close up to the bottom of
the truck and the truck is drawn to one end of the row of chimneys to be out of
the way.
When it is required to sweep any one or other of the chimneys the two barrels
are turned simultaneously so as to unwind one chain and to wind up the other. In
this way the truck can be caused to travel along the rails and can be brought over
any one or other of the chimneys. When it has been brought into the position
desired the barrels are set free the one from the other and the weighted brush is
allowed to descend into the chimney over which it has been brought-it can then
be moved up and down within the chimney by the chain to which it is suspended
being alternately wound up on to or allowed to unwind from the barrel to which
it is compected. The other barrel during this time is held stationary.

page_text: To prevent the escape of soot from the top of the chimney whilst it is being
swept we employ a disc or cover which rests on the top of the chimney when the
brush descends into it, the chain passes loosely through a hole formed through the
centre of this cover.
When the chimney has been swept the chain which carries the brush is wound
up until the cover has been lifted from the top of the chimney and the brush has
been brought close up to the underside of the truck-the two barrels are then
again made to revolve together so as to bring the truck back to the end of the row
of chimneys where it is to remain whilst out of use.
The soot which is dislodged by the brush when a chimney is being swept falls
down the chimney and in order to prevent the soot from falling into the fire place
at the bottom we provide a hinged flap by which the passage from the fire place to
the chimney can at this time be closed and a passage from the bottom of the
chimney be simultaneously opened into a closed chamber or receptacle having a
pan at the bottom in which the soot may be collected and subsequently removed.
The apparatus above described will also be found very serviceable in case of fire
in any of the chimneys as the cover which is above the brush can then be made to
rest upon the top of the chimney and stop all draught through it, whilst at the
same time the flap at the bottom of the chimney can be closed and the brush be
passed up and down so as to extinguish the flames.
Figure 1 of the drawing hereunto annexed shows an elevation in section of part
of a house fitted with chimney sweeping apparatus in the above described.manner.
Figure 2 is a plan view of a stack of chimneys with a rail along each side of it.
Figure 3 is a side elevation of the winding barrels. Figure 4 is a plan view and
Figure 5 a side elevation of the moveable truck and weighted brush. Figure 6 is
a cross section of the rails along which the truck runs or slides. Figure 7 is a
vertical section of the lower end of one of the chimney flues and of the apparatus
applied to it to catch the soot when the chimney is swept. Figure 8 shows a front
view of a stove which may advantageously be used when these means of catching
the soot are adopted.
In these figures A A are chimney flues-B B are horizontal rails fixed along the
two opposite sides of the row of chimneys and at a slight distance above them.
C is a truck or slide capable of being moved to and fro along the rails B. D is a
weighted brush suspended by a chain E which passes upwards through a hole in
the centre of a loose disc D* then over a pulley on the truck C then downwards
over a guide pulley F and down through a small passage in the chimney stack into
one of the attics or upper rooms of the house. G is the other chain led up through
the same small passage, over a guide pulley F, over another pulley H. at the
opposite end of the stack and then back again and secured to the truck. The end
of the chain E within the room or attic is wound on to a roller I and the chain G
on to a roller K—both these rollers are mounted loosely on a fixed spindle. Each
roller has a toothed wheel fast with it, one of these I' has gearing with it a toothed
wheel I' fixed on a spindle L-The other toothed wheel K¹ has gearing with it a
toothed wheel K' which is also carried by the spindle L but which can be slidden
along it by a clutch lever M so as either to bring it into position to gear with the
toothed wheel K¹ or to disengage it from this wheel-N is a lever the lower arm of
which is made to enter between the teeth of the toothed wheel K¹ and so to lock
and retain this wheel whenever the toothed wheel K is disengaged from it.
When the brush is out of use it is lowered into a flue or chamber O at the end
of the row of chimney flues so as to be out of the way as shown by dotted lines in
Figure 1-the disc D* then rests on and closes over the top of this chamber and
protects the brush from rain. During this time the toothed wheel K is out of
gear with the toothed wheel K¹ and the toothed wheel K¹ is locked and held fast
by the lever N. When any one or other of the chimney flues has to be swept the
spindle L is turned by the crank handle at its end so as to revolve the barrel I in
a direction to wind up the chain E and so lift the brush into the position shown
by full lines in Figure 1. The toothed wheel K³ is then by means of the clutch

page_text: lever M shifted endwise along the spindle L to bring it into position to gear with
the toothed wheel K' and the lever N drops clear of the teeth of this wheel so that
it is free to be revolved. The spindle L is now turned in a direction to wind up
the chain G and unwind the chain E-this draws the truck or slide C along the
rails B. When the truck has been brought over the top of the chimney which is
to be swept (which is indicated to the man working the apparatus by marks affixed
to the chains) the clutch lever M is made to slide the toothed wheel K' end wise
along its spindle and disengage it from the toothed wheel K₁ and as before
explained simultaneously cause the toothed wheel K¹ to be locked by the locking
lever N. The spindle L is now again turned in a direction to unwind the chain E
from the barrel I and the weighted brush descends into the flue to be swept and
the disc D* rests on the top of the flue and prevents the escape of soot from the
top. The brush can now be moved up and down in the flue by winding up or
unwinding the chain E and so effectually sweep the chimney. When this has been
done the brush and truck can be brought back to their original position or can be
moved over any one of the other chimney flues which may require to be swept.
The soot which is dislodged in the flue which is being swept drops into a receptacle P
at one side of the fire place which is at the bottom of that flue-the passage from
the fire place to the flue being at this time closed by a hinged flap Q as shown at
Figure 7.
When the chimney has been swept this hinged flap can be turned into a vertical
position as shown by the dotted line and the receptacle P will then be shut off
from the flue and the flue opened to the fire place. The receptacle P may be
formed as a slide or drawer to be drawn out at the front of the fire place so that it
may readily be taken away and emptied.
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 combination of the barrels I and K chain G and E weighted brush D
truck C and rails B substantially as described.
2. The means and apparatus to facilitate the sweeping of chimneys substantially
as herein before described and illustrated in the drawing annexed.
3. The combination of the soot receptacle at one side of the fire place and the
binged flap either to shut off this receptacle or shut off the fire place from the
lower end of its chimney flue substantially as described.
