mmrwi smmmmmim To all whom it may c mm-f 3e it known that I, FRANCIS E.- SWIFT,

a citizenof the United states yresiding at and ordinarylindirect radiatois and ventilating apparatus.

, The 0mm of the .i yem i n isid r side an apparatus'ivhichis adapted to the various kinds goi? fuel and par-tieularly, to the rheaper fuel known as and also to provide means tosupply each radiator with fresh cold air frornthe outside and venti late by taking the cooler and foul air irhich naturally settlesto the floor) and sending it u-pjthe smoke flue as hereafter described.

A f rth" r object of my invention is to proiide an apparatus with two separate and distinct'furnaces, one on either side of a series of down-draft flues which are arranged to receive the products of combustion, hot gases and smoke from both furnaces at the same time or separately et diiierent times. 'lhis apparatus is adapted to he operated ec' 01- nor nically in milder weather, siiehas pre' rails in the fall or early spring, and also may be run. to, its full capacity by firi'n hoth furnaces during the extremely [col weatl1er, tliereby insuring a proper de ree ofheat during the entire period when eat is required to greater or less-degree.

A' further-object of the, inifentiofi is to provide a ,f ur'nace'l-in which difier'ent fuel maybe used at one and the same time, for example, i v coke and wood, or gas in one side and any kind of fuel in the other, at the, sameti me, I attain these objects .the device here described and shown intheacconipanying drawings in which: a

This suction flue is constructed of cast ironand is in connection with the :uexcending flue 9* which'conductsthesmoke to the smoke box to which 'is connected a smoke pipe 11. Both the ascending flue and the foul. air suction flue are cast in one piece" with a partition between them. The manner of the construction of this double flue causes an extraordinary draft on the foul air ducts; viz. the heated partition in properly proportioned sizes and the deflecting damper near the top of the ascending flue 9*? causes an intermingling) discharge of both flues into the smoke o'x: hence a.\'ery strong suction on the foul air ducts.

While I have herein shownand described one form of my invention'I wishit to be understood" that this particular form has been chosen for the purpose of illustration and that I do not wish to be limited to the details of construction shown and described, for obvious modifications will. occur to a person skilled in the art.

What I believe to be new and what I desire to secure by Letters-Patent isanapparatus of the class described,

p tlal v er; controlled throats leading from sa d hre boxes to said smoke. box,'z1gz"ag down draft flues including a plurality of hori-.

zontal. vertically spaced flues', connected alternately at their-front and rear ends, an

ascending 'fiue connecting the rear end of lcl spaced fire boxes, a smoke box, damthe lowermosthorizontal fine with said smoke box, a damper at the top of said ascendin'g flue and a smoke with said smoke box.

2Q Inan apparatus of the class described, the combination of a series of'down draft flues arranged to receive the products of combustion, fire boxes arranged on either side of said down draft flues,and means for dnectlng' into said flues the products of combustion from both fire bOXGS e1th61' simultaneously or at difierent tunes.

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