HENRY VATTER, vOF LAJVRENUE, MASSACHUSETTS.

IMPRGVIEIMNI" ICN' RETURN-LITE STOVE-PIPES.

. Specification forming part oj'Letters Partout No. 7 7,684, dated May 5, 1868.

To all whom 'it may concern Be it known that l, HENRY VATl R, a native ot' Neustadt, in the Kingdom ot' Prussia.,

at present temporaril y residing at Lawrence, in the county of' Essex .and State of Massachusetts, have invented certain new and useful improvements in .Return-Fluo Store-Pipes, of which the following is a full, clear, `and eX- act description, reference being had to the accompanying drawings, making part ot'this specification, in whichl Figures l and 2 arovertical sections at .rigbtangles with euch other; Fig. 3, a trunsverse section on the line A. B of Fig. l 5 Fig. 4, a bottom eudview; Fig. 5,'a side. view of a return-ilus pipe, to be used Without elbows.

My invention und improvementin returnlue stove-pi pes consistof' a central partition, A, which :is iitted and fastened to the inside oi' the rollin] pipe, and extends from near the,

top dow'irward toa littletbclow the upper side ol' the outlet B, and' in combination with such partition ot' u tongue-shaped damper, C, which is adjustable to allow theI smoke und gases to pass directly from the stove t0 the line of' the' chimney, or upward over the top of the partition, und downward on the opposite side thereof, und then through the outlet B to the chimney. v

The object of' this invention is to allow the stove to he set nearer the chi'iune* nud thereby woumnizn. in room, to save considerable heut in cold weather, or to allow the heut to pass oli .in wurm weather, and ull with a clicup and simple device.

ln Fig'. l., l) is the circular tlangeator near the back corner nt' the stove, :i portion, lt, of

` which is also shown. The return-Hue pipe is placed on the outside ot'thi,l llauge l). lheoutlet branch li being applied tothe pipe at the proper height, enters the hole in the chimney.

vWhen the swing damper l.) is set as indicated by dotted line G', the smoke and gases pass nearly dircctl)v from the stove to the chimney, as shown by au arrow l, und when the damper U is setas indi ated, then the smoke and erases pass upward overthe top ot' the partition A and downward on the opposite sido thereof, and through the outlet B to the chimney, as

indicated by the arrows 2, thus accomplishing with a single stove-pipe without an elbow what has formerly been done with two parallel pipes and three elbows.

The return-tiue desired, and still allow most of the heat to pass nearly direct to the chimney when not wanted iu the room, by simply' adjustiugthe damper U.

This lust-named 4operatimi cannot be accomplished with the two parallel pipes, as all the Vgases and smoke pass through the whole length of' such pipes and cannot be turned .in another and more directcourse.

The damper C swings on u rod, g, which passes through the pipeand is fastened to the top of the damper. The projecting' end d of y therod is bent or turned over, as shown, and bears on a curved piece, e, ou the pipes, to hold thedampcr when set.

My invention nia-y he readily applied to a stove which has au outlet at the back instead ot' ou the top, by means ot a short elbow be.-

tween such backoutlet and the lower end oi' the return-flue pipe, or bya brauch, Ii, similar to the outlet l5, but at theopposile side ot' the pipe anda little more than its size lower down,

as shown in Fig. 5, and then a movable stopple may be placed in the lower end ofthe pipe, ns in the top end, and the inside ol suoli pipe may then be cleaned without reuiovingthe pipe or disturbing the stove.

Only a limited drul't can be produced where two vertical parallel pipes are employed, but in the usent' my invention the draft'. can he increased-or diminished or regulated at pleasure.

What l claim as new, und desire to secure pipe maybe of any length
