WILLIAM J. MCCORMICK, OF TRIVOLI, ILLINOIS.

FLUE-CLEANER.

Speeication of Letters Patent.

Patented March 5, 1907.

Application filed July 1l, 1906. Serial N0. 325.672.

To all whom t may concern:

Be it known that I, WILLIAM J. MICK, a citizen of the United States, residing at Trivoli, in the county of Peoria and State of Illinois, have invented new and useful Improvements in Elue-Cleaners, of which the following is a specification.

This invention relates to flue-cleaners designed especially for cleaning stovepipes, and has for its objects to produce a comparatively simple inexpensive device of this character which in practice may be conveniently manipulated for cleaning the pipe and one which may be readily adapted for cleaning the pipe joints or elbows.

With these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a sectional view through a stovepipe, showing the cleaner applied for use, the cleaner being MCCOR- partly in section. Fig. 2 is a side view of the cleaner. Fig. 3 is a section taken on the line 3 3 of Fig. 1.

Referring to the drawings, it will be seen that the cleaner comprises a handle 1, preferably composed of a length of rod metal and terminating at its forward end in a flattened portion or head 2, to which is attached, by means of transverse screw-bolts 3, provided with thumb-nuts 4, a pair of forwardly-extending slightly-divergent spring members or arms 5, equipped at their outer ends with perpendicularly-disposed substantially semi* circular scraping members or blades 6, preferably composed of heavy-weight sheet-iron and riveted or otherwise secured to terminal engaging portions or iingers 7, formed on the arms 5, one of which latter is provided at its rear end with a rearwardly-opening slot 8, j

adapted to receive the bolts 3 for detachably engaging said arm with the handle 1.

In practice the spring-arms 5 will yield to permit introduction of the scraping-blades 6 9, as seen in Fig. 1, it being noted that the outer curved edges of the blades conform to the contour of the inner walls of the pipe, whereby when the handle 1 is moved back and forth the soot or other accumulation adhering to the interior of the pipe will be positively scraped therefrom. When it is desired to operate the device in a flattened pipe, such as usually employed for the lower joint leading from a stove, the arm 5 having the slot 8 may by loosening the thumb-nuts 1 be readily disconnected from the handle, thus to permit disengagement of one of the blades 6 and adapting the device with only one blade to be readily introduced into and operated in the iiattened joint or in a pipe-elbow.

Having thus fully described my invention,

A device of the class described comprising a handle having a iiattened head, a pair of forwardly-projecting springarms having their rear ends arranged to bear on opposite sides of the head, one of said arms being provided with a rearwardly-opening slot, fastening-b olts entered through the head within said slot and adapted for detachably connecting the slotted arm with the handle and outwardly-projecting scraper-blades attached to the forward ends of the arms.

In testimony whereof I afHX my signature in presence of two witnesses.

WILLIAM J. MCOORMIOK.
