flfe it known that l, EDWARD S. Burner, seitipinn et' the United States, and e resident ofthe end countyv et Philadelphie, State of Penneniu,y hereinrentedeertein new and useful improvements in i'ieeting-Furnnces, of which the Afollowing; is e specification.

z-lj; invention rele `es to improvements in sting-furnaces; und the object of my invenis to :furnish un eiiicient und simple furcstions for heating; water for heating` houses of any description, 4

My invention contemplates en arrangement of parts that een be put in place or taken .down with the minimum expenditure of time und labor, luid te this end the festenings et" ille several parts ot the furnace are oi' such uirneter that if necessary thegv can he out i, )rohen without destroying' any parts of the furnace proper.

This construction is clearly shown in Figs. Je, 5, 6, end T end results in u llue the cross-section of which increases in zueu es it rises, this construction uli'ording u free nessuno for the nir, which becomes more highly heated und correspondingg'ly expended us it rises in the lues.

the lianges 16 do not extend quite to the top of the lues, and when the lines are in place the omission of the lflanges at this point forms openings 17,y Fig. 1, for the passage of smoke and other products of combustion, which are through these lopenings discharged into a smoke-liuc 18, which surroundsI the` furnace, the inner walls of this lue being formed by the outer walls of the flues 15, while its outer wall is formed by al series of thincastings or plates 19, which are secured together by bolts 20 or other suitable and convenient means.

.The top and. bottom of the smoke-flue are closed by covers 2l 22, respectively, and the ue is furnished with a smoke-collar 23, Figs. 1 and 3, which is connected withl the chimney.

From Fig. 1 lit will be seen that the smokecollar 23 is placed substantially ,opposite and at the same height as the coal-chute 3 and that beneath the coal-chute and smoke-collar are placed -cleaning-doors 24. 0f these latter there are sufficient to permit the thorough cleaning of the bottom of the ue 18. e

25, Figs. 1 and 3, is a baule-plate dividing the rear part of the flue 18 into an upper and a lower chamber.

26 is adamper in plate 25, If the damper be opened, the smoke and products of combustion, following the line of least resistance, will pass across the top of plate 25 down to the smoke-collar and thence to the chimney. If the damper 26 be closed, the smoke, &c., are forced to pass under the plate 25 to reach the chimney. This retards the draft and is not resorted to unless the re be in good condition.

27 is a sheet-iron or brick covering surrounding and inclosing the furnace, as is usual.

y ring 29 forms a seat for` the under part of the plate 28 andY is itself Afb'arried by the upper ends ot the lues 15, v'shown in Fig. 8. i

1n Fig. 9 the meansilfor securing the cover 21 of the smoke-flue 18' to the outer wall 19- of this flue are shown., 31 being a bolt, passing through the wall 19 and through a keeper 32, one leg of which bears against wall 19 and the other against cover 21.

serena 33, Figs. 1, 2, and 3, is a dust-Hue leading from the ash-pit to the bottom of the coalchute 3. This lue is furnished with a register orl damper 34:, which may be Aopened or closed, as conditions may require.

35, Figs. 1 and 2, is awater-front the inner face of which forms a part of the lire-chamber of the furnace. rlhis water-front is placed directly beneath the coal-chute 3 and at this point, in` order to form an opening for the passageof coal to the furnace, one or two of the llues 15 are omitted, their` place at the bottom being taken by the water-front or by a simple casting or plate which may be used interchangeably with the water-front. Above the coal-chute 3 short lines are used to lill up the space between the longer flues, of which there is one on either sidelof the chute.`

The arrangement of grate-bars shown and described in this application will form the subject of a separate application.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A flue for a heating-furnace having a lowerportion formed with four vertical walls and an upper portion formed with a vertical rear wall and an inner and two side walls all of which are from their bottoms outwardly, the side walls of the lower portion of said flue being at their upper ends bent sharply inward to join the lower endsot` the side walls of the upper portion of said iue so as to choke oli or contract the flue at this point.

2. The combination with a heating-furnace, of a series of air-heating flues surrounding and forming a lire-pot and a combustion-chamber,`the lower portionof each of Said flues being formed with four vertical walls and the upper portions or' each ofI said lines being formed `with a substantially vertical rear wall and two side walls and an inner, or front, wall that flare from their bottoms outwardly, each of said ues beingcholred ofi, or contracted, at the junction of their lower and upper portions.
