pipe having an anglet therein.

A further object is to provide a device which may be easily inserted within a pipe and held securely therein, but which may be easily and readily removed.

Other objects and advantages of the peculiar construction will appear in the further description thereof.

Referring now to the drawing accompanying this application and forming a part thereof, in which likerefereuce characters indicate like parts:

Figure 1 is a transverse section through the pipe showing the mounting of the damper Figure 2 is a longitudinal section through a portion of the stove pipe at the discharge end of the partition member, showing a possible arrangement of the damper;

Figure 3 is a perspective view showing a stove pipe angle in section, with the present invention applied thereto; and

Figure L1 is a broken side elevation of the partition member removed and extended for use in a straight stove pipe.

The present invention comprises a partition member consisting of two sections 1 and 2, which are hinged together at their ends. as at B. The sides of the members 1 and 2 are turned laterally in the form of flanges at. and these flanges have pivotally secured thereto adjustable supporting bows` each consisting of two arcuate members 5 and G. Fach of the members 6 are provided with a slot 7 therein adjacent their free ends, While the members 5 are provided with bolts 8 which entend through the slots ,T and are lly Vthis arrangementnit-willtbel noted5 thatithe devicerrmay beiv applied to slightlyI varying `si-:aesfof pipes,

clearly shown in Figure 3 of the drawings, and, 4i'nmvhich case, it ibeconies' necessary to contract and fpivotallyr adjust thebows 5 and Gstoperinit-ofeiits .extending `past the angle Vhen applied within a stove pipe the device serves to divide the pipe into` two longitudinal passages, one preferably approximately twice the size of the other said passages being separated by the division meinbei's 1 and 9..

In applying the device to a stove pipe` the member 2 is always placed close to the stove, and, adjacent the free end of the member 1, whether applied to a straight or elbowed pipe, and located, in the stove pipe, is a double damper consisting of the two segments 11 and 19.. The segment 11 has attached thereto, as at 13, the sleeved clip 14, which is positioned intermediate of the two similar clips 15 and 1G securely vattached to the segment 12, as at 17. Damper shafts 18 and 19 extend through the sides of the smoke pipe at opposite points and are in alignment with each other. The shaft 18 extends through the clip 15 and into the clip 14, while the shaft 19 extends through the clip 16 and into the other side of the clip 1&1, said clip let acting as a journal for the shafts and aids in keeping them in alignment.

One of the shafts is attached, in any desirable manner as b v a suitable cotter not shown, to the clip 14 for regulating the segment 11, and the other sha-ft is rigidly attached to the clip 16f0r regulating the segment 12. Means for manually regulating either or both of the segments are provided adj acent the outer ends of the shafts 1S and 19.

The free end of the section 1 has an arcu iio ately shaped cut-away portion Aformed therein, as at 20, so that, when the segment 12 is disposed transverse the pipe and the segment ll at an angle of approximately 45 degrees downwardly, the smoke and gases rising in the larger passage of the pipe will be forced by the segment 1l through the cutaway portion 20, and the segment l2 will aid in directing the unburned gases back to the fire; through the smaller division of the flue.

As is obvious a great many different combinations oi'" draft conditions may be produced by the regulation of the segments ll and 12 in accordance with the different conditions of combustion within the stove or the division Wall for holding same in position within the pipe, and a double .adjustable damper within the pipe adjacent the upper end ot' the division Wall whereby to deflect gases passing through the pipe at the end of the wall and cause a portion of same to return y.Within the pipe. f

2. An attachment for stove pipes including a partition member consisting of a plurality of plates hinged together at their adjacent ends for movement to lie either in a common plane or in planes at an angle to each other, adjustable supporting members carried by the plates, said plates and supporting members being adapted for engagement Within a smoke pipe to effect a division or' the latter into two passages by the partition member, with the supporting members engaging the smoke pipe wall, and damper members adapted to be mounted in a smoke pipe for independent operation to close the separate passages formed by the partition member` In testimony whereof I hereunto ailix my signature in the presence of two witnesses.
