HENRY o. COLEMAN, or tawnnncnnnns, TEN SSEE,


Application filed August 23, 1923. Serial No. 658,886.

This invention relates to a flue scraper and has for its principal object to provide a simple and efficient means which is especially adapted for use in connection with removing soot from the inner walls of a stove pipe while the 'sameis connected to the stove and chimney, thus obviating the necessity of having to remove the Stovepipe from its position whenever it is necessary to clean the same.

Another important object of the invention is to provide a flue scraper of the above mentioned character, which is of such construction' as to enable the same to be ex- 7 tended to various lengths thereby enabling the same to be used in connectionwith stovepipes of various lengths. I A further object of the invention is to providea flue scraper of the above mentioned character, which does not interferewith the passage of smoke through the chimney and will also prevent the possibility of causing the dust or soot to escape through the stovepipe and enter the room.

A further object of the invention is to provide a flue scraper which is simple in construction, inexpensive, strong, durable and furthe* well adapted for the purpose for which it is designated.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawings forming a part or" this specification and in which like numerals designate like parts throughout the same Figure: 1 is a sectional view of a horizon tally arranged stovepipe and the usual elbow v associated therewith atone end and showingmy improved flue scraper in position for use tlrerein.

'l' i jure 9 is a pla viewc m flue s "r oer.

' 'niie fl is a view s he pted to lie assoei te t i o e" wlen it is desired to le "'l1- h same.

n the drawims where n for the purpose of llustration is shown the preferred embodiment of my invention. the numeral 1 designates the horizontal section of a stovepipe of the ordinary construction and is provided with the usual elbow 2. it being understood that this pipe is connected up to the stove and chimney in the well known nianuen The elbow 2 is provided with. an

opening3 thereinand adapted to extend through thisopening is the elongated rod 4:.

The outer end of this rod 4 is coiled around itself as shown M35 in the'drawings to provide a suitable operating handle 6. The inner end of the rodv 4 is provided with the looped portions Y and 8 in the manneras more clearly shown in F igs. 1 and 2 of the drawings and the purpose. of this construction will be hereinaftermore fully described.

Slidably and adjustably supported inthe looped portions 7 and 8 of the elongatedrod l is the inner end of a scraper blade supporting rod designated by the numeral 9. The outer end of this supporting rod 9 is offset as shown. at 10 in the drawingsand a short section or piece of wire 11 has one end c0iledaround the rod 9 adjacent the ofliset portion 10 in the manner as clearly shown at 12 in the drawings. The purpose of such an arrangement is to provide a pair of diverging arms at the outer end of the supporting rod 9 and is clearly shown in Fig. 2 of the drawings. s

I The outer free ends of the arms 10 and 11 are adapted to be bent back upon themselves and'provide' a means for pivotally supporting the scraper blade 13 and this scraper blade 13 extends transversely across the nher f ee ends of the arms 10 and 11. The scraperblade 13 is pro ided witha curved scraping cage 14 which is adapted to cooperate with the inner wall of the flue pipe 1 when in use. I i

As s ated abo e. the rod 9 is slidably and adjustably received in the looped portions 7 and 8 of the elongated rod l. It may be here stated that this rod 9 is trictionally en-aged with these looped portions and the in er Free end of said rod El is-bent around the loop 7 asc earlvshown in Fi t/Z of the fii r i l hen it is desi ed to sh ten the w**--- th s evice the rod 9 mav e forced lone-i 'n lv alone tle rod 4 th o gh the lio e'l port o s 7 and 8,

In Fig. 3 ot the drawings there is shown the rod designated by the numeral 15 and this rod 15 is provided at-its forward end with a pair of loops 16 and 17 respectively in a manner similar to the looped portions 7 and 8 provided on the inner end of the elongated rod 4. This rod 15 is adapted to be associated with the supporting rod 9 the elongated t'vhen it is desired.

to extend the length of the scraper blade supporting rod in order to accommodate its use to a long section of stovepipe. The extending of the supporting rod 9 with .relation to the elongated rod l is accomplished by inserting the lower end of the rod 15 in the looped portions 7 and 8 thereof and having the looped portions '16 and 17 respectively of the rod 15 adapted to slidably and adjustably receive the lowerend of the supporting rod 9; In this manner the various rods may be extended and held in their proper adjusted position by means of the frictional engagement of the looped portions with the respective portions of the rods supported therein.

In applying the extension member, shown in Fig. 3, to the device as shown in Figs. 1 and 2, the end of the rod 15 opposite that having the loop 17 formed thereon is adapted to be engaged and bent around the loop 7 of the rod 4 in a manner similar to the showing in Fig. 2, wherein the end of the rod 9 is engaged with said loop. In other words, this rod 15 is merely an insertable extension to be placed between the rods 4 and 9 when the scraper is to be used in .a pipe of extended length.

With the parts arrangd as shown in Fig. 1 of the drawings, by pulling'outwardly on the handle 6 the scraper blade 13 will be caused to have its curved scraping end 14: scrape along the bottom of the stovepipe 1 and cause the soot which has collected on the inner walls of the stovepipe to be carried forwardly and discharged into the stove where it is burned. lVhen not in use the coiled portion 5 will fit in the opening '3 provided in the elbow 2 and thereby prevent the possibility of any smoke being discharged from the stove from entering the room. I

The simplicity of my flue scraper enables the same to be readily and easily operated and does not re'quire'the necessity of having to remove sections of stovepipe from their proper positions in order to accomplish the desired results. It is to be further understood that when the scraper is in an inoperative position, the blade is so arranged as to permit the smoke to pass through the stovepipe without being obstructed.

I From the foregoing description of the construction of my improved apparatus, it will be seen that I have provided a simple, inexpensive and efficient means for carrying out the objects of the invention, and while I have particularly described the elements'best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention. I I

What I claim as new and desire to secure by Letters Patent is g A I 1. A flue scraper comprising a rod, the outer end'thereof forming a handle, the inner end of said rod being provided with looped portions, a supporting rod slidably and adjustably mountedin said loopedportions, and afscrap'er blade carried by the outer end of said supporting rod. H

2. A flue scraper comprising a rod, the outer end thereof forming a handle, the inner end of said rod being provided with spaced looped portions, a supporting member slidably and adjustably mounted in said looped portions, the outer end of said supporting member being provided with diverging arms, and a scraper blade connected to the free .ends of said arm's.

8. A flue scraper of the class described comprising an elongated rod having its outer end provided with a handle, the inner end of said elongated rod being provided with spaced looped portions therein, a scraper blade supporting rod having its inner end slidably and adjustably received in said looped portions, the outer end of said supporting member being offset, a piece of wire having one end coiled around said supporting member at the offset portion thereof to'provide a pair of diverging arms at the outer end of said supporting member, and a scraper blade extending transversely across the free ends of said arms and pivotally mounted thereon.

In testimony whereof I affix my signature.
