To ull 1r/Qur fit may concern:

Be it hnovvn that l, WILLIAM. hl. FURTH- 'nasvg citizen of the United States, residing at Uhicagmin the countyof Cool: and State ol? illinois, have invented a certain new and 'oo lul llnproven'ient in Furnaces7 olf which 'the following is a full, clear, concise, and enact description.

My invention relates to improvements in heating appliances. l l

lhe objects ol' my invention are to provide a device of this character of increased ehliciency; to provide au improved arrangement lor insuring continued circulation of the air to he heated. through the heatingchalutiers; to provide improved means or insuring a continuous supply of fresh air to the. heating chambers; to provide means tor suppl ying heated air to the combustion chalnher; and to provide a device which is simple7 durable and which requires little attention.

have illustrated, in the accompan ing drawings, the preferred enihodinient oV the invention. .llt 1s to be understood, however, that said invention may he embodied in other terms.

ln the drawings, Figure l is a sectional elevation of the preferred structure; Fig. 2 is an. enlarged, top, plan view of the adjustable drip pan; lli r. 3 is a bottom plan view of the combined leector and cover; Fig. 4i: is an enlarged bottom plan view of the hui-ner cap; Fig. 5 is an enlarged. top plan view of the burner with the cap removed; Fig. t3 is an enlarged, sectional elevation of the leed tube; i is an enlarged. top plan view of; the overflow cup; and Fig. S is a perspective view ci a support.

.lfhe device comprises a burner l of suitahle construction. hereinafter described more fully, said burner being located at the hase oit a combustion chamber 2, the latter being supported on suitable standards or legs rthe heated products olf combustion pass upwardly through the chamber and out through. a suitable pipe or outlet fl. llithin the clmiubei' Q an inner chamber 5 is located. the latter being spaced from the former and suppe d on suitable standards or brackets G., 'u'l'le ohy a free spacegis prolidcd around all sides of said inner chamber, the latter heilig; thereby subjected to the above men tioned heated gases as they pass upwardly Fresh air is admitted to from the burner.

the inner chamber 5 through a suitable pipe 7. rThe apparatus as illustrated is shown mounted in an inclosure 8, as, for example, a rooin of: a house7 the chamber.' 5 having open communication, therewith, whereby the heated air 4itrom said chamber passes directly into said inclosure 8 and circulates in the manner lindicated. by the arrows. However, 'it is to he understood that the device may he used as a 'furnace `and located in the basement of a building in the usual manner, under which circumstances the heating chamber would communicate with. the usual pipes leadingl to the upper doors. ln the arrangement shown, wherein it is intended to maintain a certain predetermined temperature within a given iuclosure, the inlet pipe 7 extends preferably throilgh the wall of said inclosure whereby fresh air is drawn in 'from the outside. The products of combustion also pass out of said inclo sure through the pipe --l.

The burner l, previously referred to. is preferably an oil burner. liquid uelheiug supplied through tlfe pipe 9 and the How there of cont-rolled by a suitable valve having a housing 1G and a plunger il inthe form of a needle valve, the latter having a small opening therein (see dotted lines in Fig. l) whereby there is a continuous, although limited, iow of oil through the valve even wher. the plunger is seated. Said plunger is car ried on a pivotcd lever l2, movement being .imparted to the latter by a suitable thermo static expansion device 12 having thin ilexible walls, the detailed construction of which device is well known. The movement of the lever is limited hv a suitable adjusting device 1.4 which limitsl the. upper movement of the lett hand end of said lever as shown in Fig. `l. The thermostatic device controls the valve in such`a manner as to vary the fuel supply and thereby maintain a deiinite predetermined temperature in a manner which will he more fully described hereinaft-er.

rllhe oil or other fluid. after passing' the valve just described. accumulates iu a rcccp tacle 15 having; glass walls lll wherehvY the level ot' the fluid may he observed. A pipe 17 leads from said receptacle und connects with a suitable coupling; 18 (see Fig. 6). Said coupling.' has screw threaded engage ment with a. tube lSl. the latter havingv a` plurality ol radial openings Q0 at its upper end mettere but being closed at the top. Aniiner adnormally above said holes. To aid in iuinstable tube 21 is also carried by said bush- Specting the burner and also in cleaning the ingvl8and is provided at its lower end with device, the bottom 320i the inner cliainber a funnel shaped extension 22 provided with 5 is made removable in an upwardly circo a suitable screen 23 preferably of gain-Zea through which the air is.s c1 eened,

l tion, being provided with a which l suitable ringl or eyelet 33, Wh

ereby a rod Twith a hook' on the passes upwardly through the inner tube to end may be lowered through the chcinbor the burner The oil which entersthrough and said bottom raised thereby, exposing the pipe 17 ills the tube 19 and,A flowing out the burner and its associated parts to View 1c through the'openings 20', partially lls the and rendering theni accessible for cleaning cone-shaped recess in the burner 1. The purposes. Said bottom comprises a. pair ot thrown downwardly, a feature that is of level of the liquid fuel in said recess is the same as that in the receptacle 15. Said fuel, upon being ignited, furnishes the necessary air or other medium in the disks 34, 35 held apart by :i pedestal 3G. The lower disk acts as a delector, as shown by the arrows.

It will be seen. that there iS-iio direct conimunicatioii between the passages through which the burnt products of combustion are drawn and the air within the inclosures 8 which it is desired to heat. Accordingly said air is not contaminated. The fresh air is drawn in through the outer walls of said inclosure and passing directly into the henting chamber 5 iiear the lower end thereof, it passes upwardly about as indicated by the arrows and by virtue of the central enlarge ment of said heatingl chamber, ample heat is such that air is supplied to theburner ading area is provided to heat said air the dejacent to the liquid fuel through the opensired amount. The heated air passing out ing lin the burner cap 26 and also through th area ofthe of because of the cone-shaped recess or receptacle. Accordingly the flame may be edjusted by adjusting said level by the operation of thev inlet valve.

` he burner l includes a suitable frame or spider 24, the latter carrying also a cylindrical element 25 having a cap 26 with an ei'ilarged central opening. vThe construction vwill be readily understood from Fig. 1 and the tube 21. A further supply of air is adcu ates within the i'nclosure about as shown inittedaround the cylindrical element 25. by the arrows, and part ot it is oiawn imo If the fuel level in the burner becomes so the burner to supply the necessary orygjgen.

high that the oil overflows, said oil is caught he air Supplied to the burner accordingly and restrained by a circular Harige 27 at the is heated air. IThe air discharged into the in :f base of the burner l. If the oil overflows `closure is heated not only from having been said flange, it is caught Within a shallow pan within .the chamber but also by beingl 28 adjustably supported on the screw threadbrought in direct contact with the walls 2 of ed tube 19. Said pan, by being adjusted up the outer inclosure of the heater. recordor down, acts as a damper to vary the air ingly very little heat Wasted. The thersupplied to the burner and also acts as a Shad niostatic device 13 responds to the tempera.` the light ture of the heu-ted air and by varying the fuel supply, maintains said air at the desired predetermined temperature.

e to prevent from being considerable importance in certain classes o service I l iat I claim is: i The pan 28 is provided with a plurality n a heating device, a cylindrical chamber o f holes 29 through which the accumulated open at the top, and having a centi-al enlargement, and a removable bottoni compris` ing a pair of disks spaced apart by a central pedestal, one of said disks acting as a heat deiector. i

In wit-ness whereof, iny naine this 26th day d being provided with a d through Which the overflow oil may be rel, hereunto subscribe or" July'.y A. D. 1913. FUlt'il-ilvljlilil'.
