STOVEPIPE FOR" FLU E-CLEANINVG.

SPEQIFIGATION forming part of Letters Patent N 0. 728,508, dated May 19, 1903. Application filed November 26, 1902 Serial No. 132,852. (No model.)

To all whom it may concern;-

Be it known that I, HATTIE M, SHIELDS, a

' citizen of theUnited States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Stovepipes for Flue-Cleanin g; and I do declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a partof this specification.

Myinven tion relates to flue-cleaners for domestic use, and it has reference particularly to devices whereby the bottoms of chimneyfiues that have stovepipes connected therewith may be cleaned and also whereby the stovepipe portions of the flues may be cleaned without taking them down from their positions.

The object of the inventionis to provide means whereby flues maybe cleaned while the stoves or furnaces connected therewith have fires in them and without causing dust to arise in the atmosphere of the rooms and also without causing soot to fall upon the My invention consists in a stovepipe-elbow having a novel form of opening and a door therefor; and the invention consists also in. the novel parts and the combination and arrangement of parts, as hereinafter particularly described and claimed.

Referring to the drawings, Figure l represents a cooking-stove in elevation and a stovepipe having'my improvements and a portion ofa chimney in central vertical section connected with the stove, showing a scraper in operative position in the pipe; Fig.2, a perspective view of a scraper; Fig. 3, a perspective View of a portion of the extension handle-rod of the scraper; Fig.4, a perspective View of portions of the h'andle-rods, showing the means by which the two parts of the rod are connected together; Fig. 5, a perspective view of the latch-plate for the door of the elbow-opening; Fig. 6, a fragmentary perspective view of the elbow, showing the door latched thereon; Fig. 7, a fragmentary sectional view of the elbow, showing the form of the latch-plate in section engaged by the door- Iplan view.of the elbow, showing the form of the opening therein.

In-the drawings, a designates the stove, in the construction of which provision is made for removing soot from the bottom thereof, there being passages, as usual, through which soot from the vertical portion b of the stovepipe'may fall to the bottom of the stove. The pipepart I; usually has a damper 01 therein. At the top of the part b is an elbow A, having an opening Bin the portion thereof at the outer side of its curve or so situated that a line entering either end of the elbow may pass through the opening. A horizontal portion e of the pipe connects the elbow with the flue got the chimneyf. In forming the elbowA 7c a central section h is usually employed'in connection with a suitable number of sections at the sides thereof, and the opening B is most conveniently cut in the central section h. At the upper side of the opening a small recess 11 is cut in the metal, and alike recess j is cut in the metal at the opposite or lower sideiof the opening. A door properly adjusted. The doorhas a latch l,

normallly engaging a latch-plateD, secured to the metal adjacently to the side of the opening opposite to the rivet k, the latch-plate having three notches m, 'n, and 0, either of which may be used in adjusting the door 0 in its several possible latched positions. The latch-plate may be made either of sheet metal or of bent wire, as will be obvious, or asa light casting. I A suitable scraper E in plan is-of the fa- 5 miliar crescent shape, the convex edge being adapted to scrape the concave form of the interior of the flue or pipe and the concave edge being designed to clear the central portion of the damper and also to clear the soot when inserting the scraper into the pipe. The scraper has a suitable handle-rod which is preferably extensible andwhen so made comprises a rod F, attached at one end to the scraper and having at the opposite end thereof a side loop G, through which a rod H extends parallel to the rod F. A sliding collar I extends about the two rods between the scraper and the loop G and has a set-screw adapted to engage the rod F. The loop is attached to the rod H suitably, as by means of a hook J, turned over at the end of the rod about the adjacent portion of the collar. The opposite end of the rod H has a handle q of suitable form.

In practical use the scraper may be operated somewhat as indicated in Fig. 1, wherein it is shown in full lines and also in dotted or broken lines, illustrating the positions in which it may be operated, the handle-rod working in the recess j or the recess i, as cir cumstances may require, the door 0 being so latched that the proper recess may be uncovcred.

Having thus described my invention, what I claim is- A pipe-elbow having an opening in the wall thereof provided with recesses at opposite sides thereof, a latch-plate attached to the elbow and having a plurality of notches, a door pivoted to the elbow adapted to cover the opening and the recesses, and a latch attached to the door and adapted to cooperate with either one of the notches in the latchplate.

In testimony whereof I affix my signature in presence of two Witnesses.

HATTIE M. SHIELDS.
