To aZZ whom it may concern:

Be it known that I, MICHAEL L. SCANLON, a citizen of the United States, residing at Cleveland, in the county-of Cuyahoga and State of Ohio, have invented a new and use ful Combination Coal and Gas Stove or Range, of which the following is a specification.

The present invention nppertains generally to stoves and ranges, and relates more particularly to a. novel and improved combination mal and gas stove or range. I

It is the object of the present invention to provide a unique stove or ran e construction, which shall permit of t e consumption of both solid and gaseous fuels, both for heating the to of the stove and for heating (the oven or skin chamber.

Among its specific objects, t he presentinvention arms to provide a novel means for heating and-ventilating the oven or baking chamber.

With the foregoing general objects outlined. and with other objects in view, which will be apparent as the nature of the invention is better understood. the present invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention heroin disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

'1 he invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a perspective view of the improved stove or range. Fig. 2 is a top or plan view of the stove with the top removed. Fig. 3 is a vertical section taken approximately on the line 33 of Fig. 2, arts being shown in full. Fig. 4 is a reilhced horizontal section taken onthe line 4-4 of Fig. 3. Fig. is a sectional detail taken approximately on the line 5--5 of Fig. 3. parts being shown in full. Fig. 6 is a sectional detail taken on the line -fi of Fig. 2. Figs. 7 and 8 are sectional views taken on the lines 7-7 and 8-43 of Fig. 6 respectively. Fig. 9 illustrates the damper controlling the passage leading from the upper flue or secondary combustion chamber to the up-draft flue or outlet,

Fig. =12 is a horizontal section taken through the stove-on a reduced scale, illustrating a-modifiod form-of burner .Eor the bottom of the oven or bak' chamber. sectional detail illustrating the carriers swung to bring the closure plate over the channel.-

Reierring specifically to the drawings, the stove or range comprises a suitable casing embody-in the front w-zdl 1, the end walls Qand- 3, t e back wall 4, the bottomfi, and the t 6, which-may benssembled in any well" nown manner. Between the front and baokwolls, ere securedthe upright purtitions 7 and 8, and the horizontal parti tions-9 and 10, forming the oven or baking chamber. -'The .partition 7 forms the left hand end of the oven and cooperates with the end 3 ofthe casing-to rovidethe fire box and ash pit. a grate-11 eiug supported between the-partition T and the end 3 of the casing, as is customary. The front wall 1 Fig. 13 is a" is also provided with the parts 1'1" and 11*" leading to the fire hue and ash pit, res ectively, and is further provided with a cor 12 for normally closing the oven or baking chamber. The upper horizontal partition 9 forming the top of the even cooperates with the top 6 of the casing to define the upper horizontal flue or secondary combustion chamber 13, leading from the fire box to the down-draft flue 14 defined between the partition 8 and the end 2 of the casing. The

down draft flue 14 leads to the lower horizontul flue 15 defined between the bottom 10 of the oven and the bottom 5 of the stove casing. The top of the casin is provided with a suitable number of o :iemngs, as usual, which are normally close by the lids or covers 16, and an updraft flue 17 is attached to the back of the stove casing, and has the collar 17" at its upper end for the attachment of the stove pipe. The back of the casing is rovided with the openings 18 and 19 leading from the lower flue 15 and the upper flue 13, respectively, to the lip-draft due 17. The front wall 1 of the stove casing is also preferably provided with a cleanout door 20 communicating with the lower flue 15, and a damper 21 is provided for the opening 19 in order to control the draft, it

being noted that when the damper 21 is open, the products of combustion will pass directly upthe fine 17 to the chimney, while when the damper 21 is closed, the products and is spaced the oven, the false bottom 33 being removably supportedon' cleats 34'secured to the partitions or oven sides 7 and 8. The lower face' of the false bottom 33 with a. layer or layers of asbestoswor the like,

H 2 of the casing andlleading ofcombustion will -be' constrained to pass around the oven, and upthe-fiue 17 from the 'lower'fiue 15,,in themanner ota downdrait oven.

i The foregoing structure 'is common in stoves and ranges, and" is well understood"in the art,iso that afurther-descriptionthereof is not necessary. p v

In carrying out the present invention, a number of gas burners 23 are disposed upon the top, 9 of the oven underneath certain of the openings in the top of'the casing, a suitablegas 'su ply pipe24= being arran ed-at the end 2 o the casing, and having t e upper branches 24! extending through the end burners 23; Suitable valves maybe pro-' vided for the-branches 2d? mission of the aseous fuel to theburners 23 these valves eing Well known and not being illustrated. It is-evident that when I the-respective lids 16 are removed, the burners 23 will be exposed, and the same 'may be em Ioyed for cooking or other purposes, as

wi be apparent. v,

In order to protect the burners 23 when coal ,or other-solid. fuel 'is employed, the lids- 16 above the several burners 23, are providedwith the depending aprons 25 adapt ed'tosurround orhouse the burners 23, when the lids are in place, the aprons 25 being providedwith the-notches 26 for receiving the branches 24. ,It will thus be obvious that when the lids of the stove casing, topermit coal or -s1m1- lar fuel to be burned'withinthe fire box, the

aprons 25 will prevent the products of combustion from injuring the, gas burners 23;

Coming to the means The forembodies the following essentials.

ward portion of the partition 10 of the oven is depressed to form a gutter or channel 27 adjoining the front-of the stove casing, and the front of the casing is provided with a horizontal series of; apertures or vent ope'nings28 in advance of the channel 27, a slidin damper 29 being mounted onthe inner si e of the front 1 of the casing and having apertures .01 openings adapted to be brought into and out of registration with the apertures 28. A gas burner embodying a straight tapered pipe 31 having a series of apertures a ong its top, is disposed along the. rear or back wall of the channel or gutter 27, the supply pipe 24: havin a branch 30 passing through the casing an the partition 8 and entering the respective end of the channel 27 so as to receive open end of the burner 31 as seen in Fig. 5. The other end or tip of the burner 31 is supported by a suitable saddle 32 secured to the partition 7 within the respective end of the channel 27. a

to the several T series of. apertures to control the adare positioned in thetop for heating the oven" or baking chamber by gaseous fuel, the same the largest or A false bottom 33 is provided for the oven. slightly above the bottom of is preferably supplied and the rear end of the false bottom 33 is cleats 34, and permit the forwa'rdend of'thefalse bottom 33 to swing upwardly when withdrawn,

as will hereinafter appear. The

false bottom 33 isprovided with a series of notches36 along its inner end, and with a 37 along each side .ed e, to provide. vents leading from below the fa se' bottom 33' to the oven orbaking chamber propn'it being noted that the notches 36 and apertures 37 are back and sidesof the oven ,or baking chamber, so that the products of combustion or gases, will proceed rearwardly from. the burners 31 underjthe false bottom 33 and.

thenupwardly through the openings 30 and37.

The space between the bottom 10 of the oven and the false bottom 33 is normally closed by means of a plate 38 secured to the forward ends of carriers 39 pivoted to the partitions or oven sides 7 and 8 immediately above the ends of the burner channel or guta l m ter 27 at the forward end of the oven bottom. The plate 38 is normally adapted to stand vertic'allybetween the lower edge of the door opening of the oven or the forward side'ol' the channel, and the forward end of the false bottom 33 which terminates adjoining the,

door-'12. The carriers 39are arcuate or curved, and have their intermediate portions partitions orside-walls of pivoted to the 40 being secured-to the oven, a rounded rib the lower face of the false-bottom '33 along its forward end and having portions normally seating within the upper curved recesses of the carriers 39 to retain the carriers in position,

closure plate 38 in proper into the oven, may be readily seated upon the false bottom 33,which is heated by means of the burner 31. It isalso preferable to providea gas burner 41 below the top of the oven, which is connected with the su ply pipe 24 by. means of the branch 41. his burner is intended to radiat'e th'e heat downwardly for the purpose oi.broiling, baking or the like, as is well known.

The back 4 of the stove casing is provided with a series of apertures 42 directly below the rear edge of the partition 9 or top of the oven, which will establish communication from the oven-into the fine 17, a slidposltion. It-is evident that the vessels or objects inserted disposed adjoining the and to consequently'maintain the ingdamper 43 being carried by the back i in rear of the aperture 42 and being pro vided with apertures adapted to be brought into and out of registration with the open tures The dampers 21 and 43 are controlled by moons of gr. vertical dam-per rod 2:2, which is iourneled'slidubly through the top 8 of the stove casing, and through c rearwerdlv projecting Veer il carried by the back. of the casing intermediate the dampers 21 and L3. The upper end of the rod 22 is form-ed into a crank or handle 45 for convenience in manipulating the damper rod, and the lower end or extremity of the damper rod. is reduced in diameter, as at l6, and hes a word 47. The damper 43 is provided st one end with a pair of persllel ears or lugs 48, which normally res ccive the lower oi the thickest portion or body of the damper rod 22, to constrain the damper +23 against sliding, the ward 47 being normally disposed below the ears 18, in order that when the damper rod 22 is oscillated in depres ed condition, the word 2? will not tend to slide or octuste the damper The dsmpe rod 22 is located at one side the opening 18 end the apertures l2, and is operstively connected With the respective ends of the dampers 21 and id.

The damper 21 is pivoted to the damper rod 22, the damper 21 and damper rod having :1 novel interengaging means, as will be presently described. The damper 21 is provided with the lower and upper tongues 49 and 50 projecting from its busel end, and has a tongue 51 intermediate the tongues 49 and 50. The tongues 49 and 56 are curved gently away from the plane of the damper 21, while the tongue 5]; is bent back and curved in a direction reverse to the direction of curvature of the tongues 49 and 50, the tongues ilk-5'0 and 53 coo embrace the damper ro 22. The lower tongue l9 is provided with an upper notch or cut away portion 52 at its free end, and the tongue 51 is provided with a similar notch or cut away portion 53.

The damper rod 22 is provided with a key or projection 54 between the tongues 49 and 50 of the damper 21, which key is adapted to engaging between the ends of the tongues 49 when the damper rod is depressed, in order that the ke 54 will be engaged securely between the notch 52 of the tongue 49 and the free end of the tongue 51. Thus, when the damper rod is depressed, the key 54 in engaging between the end of the tongues 49 end 51, will constrain the damper 21 to swing with the damper rod, in order that the sniper 21 may swun to and from the opening 19 to control the raft, as above intimated. When the damper rod 22 is raised the key 5411s adapted to swung into and out of the notch or cut away portion 53 of the tongue rating to loosely 51, without swinging the damper 21. It is to be observed that when the damper rod is elevated or raised, the Ward 47 is designed to be drawn between the cars 48 of the damper 43. whereby the swinging movement of the damper rod in elevated position, will transmit a. sliding motion to the damper e3 for controlling the passage of the gases from the oven. through the apertures 43 to the: upilraft due 17. It will thus be obvious, that when the damper rod is depressed, the some is adapted to actuate the damper 21, while when the damper rod is elevated, the damper 21 will remain idle, while the damper 48 is adopted to be actuateid through the medium oi? the damper r For convenience in holding the damper 21 closed, especially when the damper 21 is idle, the lower edge of the damper 21 is provided with o notch or recess55, which is edepted to engage ever :1 lug or projection 56 carried by the back of the casing.

A com 57 is curried by the top or? thestove casing adjoining the crank 45 of the damper rod, upon which the crank i is adapted) to. ride, when the damper rod is elevated and rotated so esto move the damper 4:3 in such a direction as to open the apertures 42, the cam 57 being provided with a stop- 51' for limiting the movement of the damper rod..-

Thus, when; the damper rod is elevated and swung so as to open the apertures 42, the crank will engage over the cam 57, and. consequently, the damper rod cannot be depressed unlil swung to such it ositiori as to slide the damper d3 to norms closed posi tion.

From the foregoing, taken in connection with the drawings, it will be evident that the present stove or range may be employed for burning cool or other solid fuel, t 1e use of coal or solid fuel being clearly apparent without lengthy description. It is evident, that when coal or other solid fuel is employed, that the damper 43 will be closed, as well as the damper 29, to seal the oven or baking chamber, and that the damper 21 may be opened or closed at will, through the medium of the damper rod, without efi'ect ing the closed osition of the dam er 43. Should it be desired to remove the fa so bottom 33, when coal is employed for fuel, this may readily be accomplished, by sliding the false bottom 33 outwardly, and the rib being moved outwardly will cause the carriers 39 to be so swung, as to raise the forward end of the false bottom 33 as it is being withdrawn, the closure plate 38 swinging downwerdly over the gutter 27 so as to partly or com letely closet esame. Conversely when the ihlse bottom 33 is inserted, the carriers 39 will be engaged by the rib 40 and will be swung so as to bring the closure plate 38 to normal position between the forward end of 30 *ielse bottom-t t Q; igrssgoon F the nose bottom 85 and lower edge of the door opening of the oven; Thus; when the false bottom 33. is inserted; the oven may I beheated frombelow' by the burner 31, and a thoclosure plate 38 will prevent the escape v of the gases through the o'rward end of the space between the false hottomhd and the bottom 10.. of the oven. In :.this manner,

when the oven is heated hy'thegas bnrnerg 31,'the fiorwardend of the combustion chamber below the false bottom 33 will be closed by the plate- 38. (hi-the other hand when the false bottom 33 is removed to enable the ovento be heel-1w bycoal or similar fuel, as

usual, the-closure plate 38 will be swung oventhe channel 32, to close thesaid chennel, and to cooperate with the forward portion of the: oven bottom 10 for supporting thej' bahing pans or other vessels thereon in a oonvenientmannerand at the some time to bender the bnrnerBl inoperative.

When gaseous fuel is employed; the burn ers 23' maybe lighted for cooking end similat-purposes, the lids lfi hoving heen re- 25"II1OV$dL 'Th e oven maybe heated throu h the medium of the burner 31, as above escribed, the products of combustion seeing from the burner 31 under the false ottom- 33 "and up through the rear portion of the I e baking chamber or oven proper, the pass e of the roducts of com-' bii'stion into the iseharge no 17 being controlled by the dem er 43. This damper 43 may be readily sli by raising the damper so rod 22 and then oscillating the some, as here inbefore described. The admission of air into-the, oven may be regulatedby the damper 29, this damper being ordinarily closed, es-is preferable when the burner 33. so is employedl his to be noted that when the ddmpsr 29 is openedythe air will be admittedinto the channel or gntt er' Q7 so he to ep preach the burner 31."

In Fi 12,- a. modified formof burner is illustrated for nse'below the fslse bottom 33,

this modified form of burner comprisingan S-shhped pipe 31 having a series ol apertures along ltsto' and having one end ofiset-to boinserted into the-branch 80, similar to the burner-31. The burners 81 and 31' may be :employed interchangeably, the burner 3lcreating a la er flame which may be desirable at times. en the burner-31' isiemployed, the damper 294s preferably opened to edmit sir 'tothe burner 31", so as tofiromote combustion.
