FURNACE FLUE CLEANER Filed Feb. 12, 1934 Patented Sept. 18, 1934 FURNACE FLUE CLEANER Arthur H. Krueger, Ironwood, Mich.
Application February 12, 1934, Serial No. 710,931
3 Claims.
This invention relates to a cleaner or scraper designed for use in cleaning ashes and soot from the flues of furnaces.
The primary object of the invention is to pro- I vide a device of this character which may be positioned within a furnace flue, and constantly rotated through the flue until the soot and ashes are entirely removed.
An important object of the invention is to provide a cleaner of this character which may be positioned in the flue to be cleaned, where it remains during the entire cleaning operation, eliminating the necessity of rethreading the scraper, with each complete movement of the scraper.
With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangementof parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Figure 1 is a transverse sectional view through a furnace flue, showing the cleaner as in its operative position.
Figure 2 is an elevational view of the scraping blade.
Figure 3 is a sectional view taken on line 3-3 of Figure 2.
Referring to the drawing in detail, the scraper comprises a scraping blade indicated by the reference character 5, which blade is shaped to conform to the interior shape of the flue or compartment being scraped and cleaned.
The side edges of the blade 5 are cut away as at 6, providing recesses to receive the handle .of the scraper, the handle being indicated by the reference character '7.
This handle '7 is constructed of metallic strap material, one end of the length of strap material being formed into a loop, which supports the blade. As shown, the loop of the handle is formed by passing one end of the handle 7 around the blade where it is secured by means of the rivet 8, thereby firmly gripping the blade and preventing movement of the blade with respect to the handle.
The handle also includes an extension section 9 which is formed with a plurality of openings 10 that register with the openings 11 of the handle 7, the registering openings accommodating the securing bolts 12 adjustably connecting the extension section with the handle, and adapting the device for use in cleaning flues or furnace compartments of various sized furnaces.
The extension section 9 is also constructed of metallic strap material, one end of the extension section 9 being formed into a loop 13, the free end thereof being secured to the main portion of the extension section 9, by means of the rivet 14,
An opening is formed in the loop, which opening is adapted to receive the bolt 15 that passes through openings in the loop portion of the handle 7, and the blade 5, thereby securing the extension to the blade 5, and providing a com- 0 plete circular handle with the scraping blade supported by the handle.
The loop end 13 of the extension section 9, not only provides a means for securing the extension to the blade, but at the same time lends rigidity to the extension handle, so that the extension may be threaded through a flue or compartment to be cleaned with the device.
This loop 13, is normally curved inwardly so that the free end of the extension section will engage the inner wall of the furnace flue eliminating all possibility of the free end of the extension moving into the outlet opening of the flue as it is being moved through the flue.
In the use of the scraper, the loop portion of the extension handle is inserted in the flue, until the end of the extension 13 is returned to that point of the flue or clean out opening, where the loop portion was inserted into the flue.
The bolt 15 is now positioned securing the loop portion of the extension section of the handle to the blade 5.
The device may now be rotated within the flue or compartment being cleaned, with the result that the blade will scrape the wall of the flue, and at the same time push the ashes, soot and other foreign matter, from the flue.
The device, while it is positioned in the flue, may be rotated a great number of times, or until the flue or compartment has been entirely cleaned.
The bolt 15 may now be removed, and the device withdrawn from the flue or compartment.
Having thus described the invention, what is claimed is:
1. A device of the class described, comprising a blade, a moderately stiff handle secured to the blade, said blade adapted to be forced through a furnace flue by the handle, and the opposite tated through a flue moving the blade through the flue.
3. A device of the class described, comprising a scraping blade, a moderately stifi handle, said blade having notches in the side edges thereof, said handle being fitted around the blade and engaging within the notches, the opposite end of the handle being secured to the blade, providing a circular handle for the blade and adapted to be rotatedthrough a circular flue.
