' V invention relates particularly to ranges. e 'invention is illustratedjin connection with a coal-gas combination range butvarious' features thereofmay be employed with either type of range separately and with other kinds of ranges. A -prima'ry object of theinvention is to provide an improved and simplified range construction and in which,various features of improvement I are embodied. Thesefeatures'include a reintorcedf'frameiconstruction in which the sides of the range support freely "the top, burners and top late yv eme us r lfienj hg' wit vthe frame top here'toforein use, an improved frame construction in which the side walls 'are provided with conformations which buttress thewalls and t'akethe place of fpostsor beams, an improved circulation passage fordischarged gasesby which th eat therein isutilized, aheatingconduit by 20 whichfr'esh air is 'causedto passithr'ough the range in contact with heatedsurfaceaj and an oven-outlet fiue by which vapors in the ovenjmay becarried to'the 'mainoutlet flue. Other objects and advanta'g'es will appearasthe specifi- Pe j1 r d I i Th; -invention is described, in its preferred embodiment, in'the' accompanying "drawings, "in which: j] I Figure 1 a view in elevation of a range embodyingfz'ny invention, the range being equipped with a 'c'ovr preferably of thefoldable type; Fig;

'7, an enlarged sectional detail view, the sectionbeing taken as' indicated at line '7 of Fig. 1;
8,-a'n enlarged detail sectional view, the section being 'taken as indicatedat line 8 of Fig. 2; -9,fa 'view similar to Fig, 8, showing a n c'dified form of the invention. I In'the illustration g iven, A designates the coal burning compartment'of the range, B, the gas burning compartment 'of the range, and C, a heating conduit disposed between compartments A andB.
' I'he walls of a the I range are preferably so con structed as' 'to dispense with the'need, for reinforcing vertical posts and'horizontal beams. In the illustration given, the frontside 1O is 'prefer ably formed "of a single casting having openings therein in whiohthe doors may be fitted'a'nd openingsfor the burner handles, etc. The edges 11 of-the front" side '10, in'the casting operation, are formed so as to present a rolled or semitubular appearance. The rolled edges 11 thus form vertical hollow posts as well as horizontal hollow beams which give to the plate 10 all the strength formerly supplied by separate posts and beams." In addition, the rolled'jedges pro jecting asthey do beyond the ,plane ofjthe, body of the'plate, protect the pla'te not only jfrom blowsbut also, to a considerable 'extent, from contact with objects which would tendtosoil or disfigure the bodyuof the plate;
The sides 12 and 13 may also be formed from a single casting. I prefer, however, for thejpure pose of economy in manufacture, to 'fofrm the sides in two castings provided with overlapping joints .14. The sides 12, and 13 are also provided withfrollededg'es 11. HoweverQas'shownmore clearly in Fig. 6, thefront rolled-edge is prefer ablycutfaway at, 15so as to provide a'straight edge adapted'to abut and forma'tight joint with the, rear side of the'rolled edge II of the front side. 10; .Thefront side 10,and the sidewall'sjfl'2 and 13 maybe secured "together by any suitable 0 7 means. As shown in Fig. 7, the walls maybe providedwithjintegral lugslfi and l'l' which are brought into overlapping relation andsecured together" by means 'of screws 18 extending through a perforation .in one flange and engage ing a threaded recess in'the other fiangel Any suitable.fasteningmeans may, however, be ern= I ployed.
My improved range top is formed ingsucha Way'as todispensewith the top frane formerly employed, while at the same time permitting the top burner elements and plates to be readily removed or replaced. is accomplishedby equipping the rolled edges 11 with lu Oriianges l9. By'employing'the tubular'edges, the "lugs 19 may extend well .into the hollow body andjjbe rigidly and securely bound'thereto, Preferably, the lugs or flanges 19 are formed integrallyiw'ith the sides12 and 13 andthe front 10 and because of the extensive attachment surface between the lugs 19 and the hollow border members 11,--there is little danger, of the breaking'ofthe lugswhen the top elements are, dropped'thereon; The
flanges or lugs 19 are equipped with, projections 29 upon which the burner plates 21"may rest. Across the coal burning compartiment AI prefer to employ a pair of cross strips 22 and 23-which rest uponthe front and rear walls of; the range and which-are provided'with lateral flanges 24' adaptedftosupport the burner plate 25 as well asone'side of the gas burner top 21*. With this construction, the burner tops 21 and the coal range top 25 may be readily lifte'd off of the supporting flangesgand lugs 'so as to expose the entire range surface therebelow. Likewisa these parts may-be replaced without the necessity-"of using bolts, screws andother likmeans. 4
The back wall of the range may be of any suitable shape and material. In the illustration given more clearly in Figs. 3, 4 and 5, the back wall includes at the top a casting strip 26 which is provided with a longitudinal channel 27. The
channel is covered by back sheet 28 thus proupper lining 32 is perforated at 33 to permit vapors from the oven to pass throughthe upper.
lining and. channel into the horizontal "passage leading to the outlet 'fi'iie 29. Below the' back strip 28 is another back strip or sheet34 which forms the remainder of the rear wall for the gas range compartment B. A cast plate. 35 closes the rear side of compartment A; as shown more clearly in Fig. 6. j V i The coal burning compartment A is provided with afirebox 36 which may be of any suitable construction; Below the fire box is supported an ash "pot 37. Below the floor 38 which supports the ash pot 37 is a second floor 39, which is spaced. from floor 38 and provides ,therebetweenfa' circulation chamber. A partition 40, which extends from the rear'wall but terminatesshort. of. the front wall, divides the compartrnent into two communicatin passages 41 and 42flThe passage 41 communicates .at its rear with a vertical passage 43 which opens just above the fire box 36. 1A similar rearpase sage '44 leading from v the .flfiue outlet 29,. cornmunicates .with fiowpa'ssage 42. .A by-pass opening or aperture 45 establishes communica'e tior'i'..between the upper portion of' passage 44 and the; fire place. This aperture iscontrolled. by adamper 46, thehandle 47 of which extends through the side 13. When the. damper is closed, the hotv gases fromthe fire box are compelled to pass throughthe vertical passage i3to the horizontal passage 41 below the fire.
box, and after having passed to the front of thepassage arereturned bypassages42fand 44' to the outlet flue 29. This circulation of the heated gases serves to heat up theinetal ofthe range walls which in turn radiate'heat to the roomand particularly radiate heat tothe freshf-airpassing; through the heating channel C which'will be described more in detail here-. inafter.

The gas burner compartment B may be of any suitable construction. In the illustration given, the upper part of the chamber affordsa/ space for the burners'48. Themajor portion of the compartment is occupied by the oven compartment .49. I I

. A drip pan 53 is preferably supported upon the top lining 32 and below burners .48., i I The operation of the range is apparent from the foregoing description. 7 k i J The oven maybe of any suitable, construction.

The damper is then closed and the heated gases caused to circulate through the conduits 43, 41,,42 and,A4,. The circulation of the hot gases not only permits fuithgr'i cpmbustion in the passages but also heats up the metal of the range and particularly the inner wall 52 which is adjacent the heating channel C.
iWhen it is desired to have access to the top portions of the range, the burner tops 21 and the burner plate 25 may be lifted off the flanges arid lugs. 19 a'nd'24.-.'-'.To again form the cooking .top for the range, it is only necessary to replace the burner plate 25 andthe burner tops 20.
