Description
-1_ SOOT COLLECTOR FOP. CLEANING CEILING INSTALLED PREFABRICATED
CHIMNEYS
FIELD OF THE INVENTIO~i The present invention relates, generally, to an improved soot collectorfor the cleaning of chimneys with a ceiling installation. IVlore specifically, the invention relates to a receptacle designed to allow for the safe and clean removal of soot and associated debris from ceiling installeel prefabricated chimneys.
13A~I~GROUND OF THE INVENTION
The design and use of devices that allow for safe and tidy cleaning of chimneys and stove-pipes is well taught and documented in the art. For instance, United States Patent No. 4,624,712 descz-ibes a bag that is used for the clean transport of chimney brushes to a work site that can also attach to a store-pipe to prevent dust from escaping into the room during cleaning.
United States Patents Nos. 91,608 and 1,271,658 both describe apparatuses for use in cleaning flues and stove-pipes, wherein the scraper cap- brusCn used for cleaning the stove-pipe or flue is inserted through a soot-collecting receptacle, such as a rubber or material bag. The bG,g is then attached to the flue or stove-pipe and the dissociated soot and debris is pulled into the soot-collecting receptacle.
The aforementioned prior art soot collectors typically incorporate a flexible bag with an access hole through which a cleaning tool is inserted. These bags are commonly attached to the stove-pipe by an elastic cuff. Several disadvantages are associated with the use of such flexible bags for cleaning chimneys, including: the potential for the bag to become disiodgsd during cleaning; limited uses due to the bag becoming damaged and/or too soiled to use ire a clean environment; and storage of the :oiled bag.
A variation on these bag soot-collectors is described in United States Patent No.
5,842,246. The chimney brushing tool described l:herein has a soot-collecting receptacle attached to the pole of a chimney sweeping brush. The soot-collecting receptacle is positioned to collect soot and associated debris of a fixed distance '~
below the chimney brush. This apparatus has limitations since it can only be used in a fixed diameter pipe and cannot be used in pipes with elbows or bends.
Accordingly, the use of various receptacles for collecting soot and associated debris in the cleaning of chimneys and stove-pipes is known. However, the prior art does not describe a soot collector tllat can be stabiy mounted on chimneys having different pipe diameters and c:an bc: used repeatedly to neatly remove soot and associated debris from a chimney without the potential of damage to the receptacle. Thus, in order to overcome the disadvantages of the known soot e;ollectors, the present 1 g inVentlon provides a reusable sturdy receptacle for collecting soot that will not become dislodged from the chimney being cleaned and can safely and neatly collect soot successively from a plurality of prefabricated chirrrneys a.nd can be operated by a single person from within the house or cottage.
~'Uf~IMA~°~ tar= THE IN~J~NI"I~~l An object of the present in°Jention is to provide a soot collector for cleaning a ceiling installed prefabricated chimney in an efficient and repeatable manner.
According to an aspect of the present invention, there is provided a soot collector for 20 collecting soot and associated debris from a prefabricated chimney with a ceiling installation, the soot collector comprising of a hollow rc:ceptac:le with solid sides and bottom, wherein an upwardly directed body protrudes from the centre of the bottom of the receptacle projecting to an open upper end of the receptacle and having a central bore allowing for the passage of a chimney cleaning device; wherein the 25 receptacle is held in position on the bottom of a far efabricated chimney by an attachment means to prevent the receptacle from becoming dislodged frorn the chimney during operation.
The soot~collecting receptacle is typically a rigid contain men witrr solid sides and a solid 3g bottom and can be cylindrical, cubical, or conical in shape made from metal, plastic, thermoplastic, polycarbonate or fiberglass, although other formats may also be envisioned. The bottom o~r~ the receptacle between the sides of the receptacle and the upwardly directed body protruding from the bottom, can be flat, rounded, convex or triangular in shape. optionally, handles can be diisposed on the outside of the receptacle to easily transport the soot collector to and from the worksite.
The optional handles also facilitate the attachment and the removal of the receptacle to and from the chimney.
Typically, the upwardly di~~ected body that protrudes i~s~om the bottom of the soot-collecting receptacle can be conical, rectangular, ~:rubic, cylindrical, spherical, tr iangular or any other sui!:able shape and has a central bore with first and second end openings respec;tiveiy formed at the top and bottom, re:~pectivel~y, of the body, the end openings being either equal in diameter or the first end opening being slightly less in diameter than the second end opening. The upwardly directed body should be of a height typically higher than the level of any debris 1:1 pat may collect in the bottom, preferably the upwardly di~~ected body should be of a heighf: of 0"' or greater. The central bore allows for the passage of the chimney cleaning device. The first end opening is slightly rounded to allov~, for smooth passage of 'the chimney sweeping device. In one embodiment, the first end opening can be provided with a gasket that forms a loose fit around the handle of the chimney/ ciear~ing device to prevent dissociated soot and debris from penetrating the environment. The gasket can be made of rubber, felt, plastic, nylon or any other flexible material or formulated from inwardly directed bristles arranged in an annular configuration.
The chimney cleanirrg de$rice for use witty the soot collector can be any one of a standard brush, scraper or combination thereof, with Either a fixed length handle or a handle to which extension sections can be added. The receptacle is preferably of slightly smaller diameter than the chimney to which it is to bc~ attached and this fits inside the bottom end of the chimney.
The attachment means may be a twist-locking coupler adapted to lock with the bottom of a prefabricated ~rhimney. Alternatively, holea could be drilled through the soot collector and a chimney's outer flange, so that screws aredlor pins hold the: soot collector in place during operation. in addition, supports such as wood or metal adjustable rods may be employed that allow the soot-collecting receptacle 'to be positioned directly beneaths a chimney.
