STOVEPIPE CLEANER OR SCRAPER Filed Dec. 11, 1939 Patented July 21, 1942 STOVEPIPE CLEANER OR SCRAPER John Fleming, Dundee, Quebec, Canada Application December 11, 1939, Serial No. 308,702 In Canada June 2, 1939 3 Claims.

This invention relates to stove pipe cleaners or scrapers.

It is well known that the interior of stove pipes become coated with soot after continued use. Various methods and devices have been employed to remove this soot. A common method has been to simply tap the outside of the stove pipe with a stick or similar article. However, this procedure removes only the loose soot and will not remove the soot that has become firmly attached to lthe interior wall of the stove pipe. Furthermore, this tapping tends to disiigure the exterior of the stove pipe.

Then again it has been customary to clean the interior of stove pipes with an old broom, a stick with a rag Wound around it, etc. However, these methods have proven ine'icient in that they take considerable time and even then a thorough cleaning is not obtained.

Accordingly, it is the main object of the present invention to provide a stove pipe cleaner or scraper which will remove the soot from the interior walls of stove pipes in a more eflicient manner and in much less time thanthose used heretofore.

It is also an object of the present invention to provide a stove pipe cleaner or scraper which may be adjusted laterally to fit stove pipes of different diameters.

It is a further object of the present invention to provide a stove pipe cleaner or scraper wherein means is provided for taking up the wear of the cleaning bristles which may become bent or worn after continued use.

It is also an object of the present invention to provide a stove pipe cleaner or scraper wherein means is provided for increasing the pressure of the cleaning bristles against the interior wall of the stove pipe when the soot coating is particularly diliicult to remove.

It is also an object of the present invention to provide a stove pipe cleaner or scraper which will remove the soot from stove pipe elbows as well as the body of the stove pipes generally.

Further objects and advantages of the present invention will be apparent upon reference to the accompanying drawing in which,

Figure 1 is a part sectional elevation of the preferred form of stove pipe cleaner or scraper as covered by the present invention.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Referring more closely to the drawing the stove pipe cleaner or scraper comprises the handle IG on both sides of which are positioned similarly shaped brush members II. These brush members are compos-ed of rigid backings of any suitable material, preferably wood, in which bristles I2, preferably wire, are anchored. At the outer end of the device the brush members are curved towards each other as indicated by reference numeral I3. The bristles I2 are anchored in the backings II throughout the length thereof as indicated in outline.

Passing through the handle IIl and connected thereto by pins I 4 are a plurality of threaded bolt members I5, preferably two. Riding in screw threaded relation on these bolt members are the thumb engaging nuts I6. One of these nuts is placed on each side of the handle and is adapted to run the full length of the bolt member I5 positioned on that side of the handle. Attached to the brush members II are a plurality of support members II which preferably take the form of metallic sleeves, said sleeves being adapted to enclose the threaded bolt members I5. These sleeves are attached at one end to the brush members as at I8. Closely adjacent to the opposite end they project outwardly as at I9 to enclose the thumb engaging nuts I6. These latter ends of the sleeves are not attached to the handle I0 in any way. The flanges I9 enclosing the thumb engaging nuts I6 are cut away as at 20 whereby the nuts may be engaged by the thumb of the user.

With this construction the brush members may be adjusted laterally to any desired position by simply turning the nut members I6 with the thumb. The nut members I6 will run along the bolts I5 and will carry the sleeves I'I with them. The brush members being attached to the sleeves II will move laterally and may be adjusted to any desired position as shown in dotted outline. Slots 2| are cut in the backings Il so that the bolt members I 5 may ride therein when the stove pipe cleaner or scraper is adjusted to its minimum size. The smallest size of the device is shown in the drawing. The handle is of a suitable length preferably 30 to 36 inches. and is provided with a crosspiece or handle 22 on the end thereof.

From the above description it is apparent that the stove pipe cleaner or scraper as covered by the present application may be adjusted laterally to fit stove pipes of different diameters by simply turning the nuts I6. Furthermore, should the bristles I2 become bent or worn through continued use they may be taken up by simply turning the nuts I6.

Then again when the soot coating is particularly difficult to remove the pressure of the bristles I2 against the interior wall of the stove pipe may be increased by simply turning the nuts I6. The rounded end portions I3 provide a stove pipe cleaner or scraper which will remove soot from stove pipe elbows as well as the body of the stove pipes generally.

I claim:

1. A stove pipe cleaner or scraper comprising a handle, brush members disposed on each side of said handle, a plurality of threaded members attached to said handle and extending radially of said handle ltoward said brush members, thumb engaging nut members adapted to ride on said threaded members, support members attached to said brush members and adapted to engage said nur, members, whereby said brush members may be adjusted laterally by simply turning said nut members.

2. A stove pipe cleaner or scraper as claimed in claim 1 wherein said support members comprise metallic sleeves adapted to enclose said threaded members and being movable relative thereto, one end of said sleeves being attached to said brush members, the opposite end of said sleeves being enlarged to partially enclose said nut members.

3. A stove pipe cleaner or scraper comprising a handle, brush members disposed on each side of said handle and being curved towards each other at one end, said brush members comprising substantially rigid backings in which a plurality of bristles are anchored, a plurality of threaded members passing through and attached to said handle, thumb engaging nut members adapted to ride on said threaded members, metallic sleeves attached to said backings and adapted to enclose said threaded members and being movable relative thereto, one end of said sleeves being enlarged to partially enclose said nut members, whereby said brush members may be adjusted laterally by simply turning said nut members, slots being provided in said backings adjacent to said sleeves to receive the end of said threaded members when the stove pipe cleaner or scraper is adjusted to its minimum size.
