'COOKING RANGE.

Application led June 3,r 1922. i Serial No. 565,681.

To all whom t may concern: n

Be it known that l, ALBERT, A. BRUDER, a citizen of the United States of America, residing at Holly, in the county of Oakland and State of Michigan, have invented certain new and useful Improvements in Cooking Ranges, of which the following isl a specification, reference being had therein yto the accompanying drawings. Y

This invention relates to a cooking range of that class in which hot fuel, as coal is utilized for heating ovens and a cooking top, although the construction of my range permits of various kinds of fuel burners being installed.

A cooking range in accordance with my invention may be characterized in the fol lowing particulars,

First, there is a central magazine combustion chamber with a warming oven above the same and baking ovens at the sides of the combustion chamber with said baking ovens providing cooking tops separated by the upper portion of the combustion cham# ber and permitting of each cooking .top being conveniently used. design of the cooking range is practically two stoves in one or a common combustion chamber serving two cooking units;

Second, the arrangement of floues about-y the baking ovens permits of heated air being withdrawn from the hottest part of the combustion chamber and circulated about the baking ovens to thoroughly heatthe walls thereof, the circulation being somewhat retarded before final exhaust so as to utilize any latent heat during the yoperation of the cooking range.

Third, the air supply necessary for a thorough combustion of coal in the magazine combustion chamber is taken care of by an air inlet pipe disposed to produce a siphonic action at the upper portion of the combustion chamber so as to withdraw any gases, smoke, or unconsumed gaseous prod-y ucts of combustion and deliver the same beneath the lire grate of the combustion chamber. In the full operation of the cooking range the draft through the fire grate or the unconsumed products of combustion delivered thereto produces an extremely live fire and hot fire bed, with the result of .a minimum waste of fuel and a minimum heat during the operation of the cooking range.

Fourth, there is an arrangement of dainpers which will permity of smoke, dust ln other words, the' the line IV-V of Fig. l;

laden `air and gases exhausting to the atm/os# phere during the firing of the 4cooking range or ythe removal of ashes therefrom, otherwise such'exhaust is defiected, by reason of the ysiphonic action y'previously mentioned and such exhaust made lindirect to the atmosphere with the exhaust gases subjected 'to the action of the lire within the combustion chamber in `order that any unconsumed products of combustion may be burned.

Fifth, the upper portion of the cooking range includes a water tank yor receptacley surrounding a portion of the combustion chamber whereby the heated walls of said chamber may heat water in the tank or receptacle. In o ther` words the tank or jacket about the combustion chamber is adapted to provide a source of warm water similar to kthe ordinary and well known type of hot water boiler or water back to the cooking stove. f

The above are a few of the features of.

myy cooking range and others'may appear as the construction is described by aid of the drawings, wherem- Figure l isv a vertical'longitudinal sectional view of the cooking range; f

Fig. 2 is a horizontal sectional `View of the samek taken approximately on the line II-II of Fig. l; f

Fig. 3 is a rear elevation section;y

Fig. i is a detail sectional view of one of the dampers of the cooking range, taken on Fig. l5 is a vertical cross sectional view taken on the line V-k-V of Fig.l 1;

Fig. 6 is a. similar view taken onthe line VI-VI of Fig. `l,`and f f Fig.-7y 's a front elevation, on a small scale, of the cooking range.r

In the drawings, the reference numeral l denotes a base or range bottom that may be supported directly on a floor or by suit able legs 2. On the base is an oblong boxlike structure comprising a front wall 3, end walls 4 and a rear wall. i

Onthe upper edges of the walls 3, A@fand 5 areend cooking tops 6 provided with the usual openings and lids 8. Between the end cooking tops 6 and extending upwardlyl yof the cooking; range, partly broken away and partly in combustion ychamber the full depth of the range. y

The upper portion ofl the walls 16 are disposed parallel and in spaced relation to theside walls to form water jacketsor receptacles 17 communicating with 'each other -by a conduit 18 suitably mounted on they rear wall 11, said wall having openings at the jacket 17 in order that water may circulate through said'jackets, one ofwhich y has a water inlet pipe 19 andthe other a water outlet pipe 20. The wallsl of the jackets 17 and the conduit 18 will be heated during the operation of the range and there will be at all times an available source o warm water.

The lower portions of the walls 16 have confronting ledges 21 `supporting a conventional form of grate 22 which has been illustrated as the rocker type. The grate divides the combustion chamber to the eX- tent-.ot providing an ash pit 23 and access ishad* thereto b-y a door 24 carried by the front wall 3.

The ash pit or lower portion of the combustion chamber divides the range structure and in the ends of said structure, below the end cooking tops 6, are rectangular baking ovens 25 the full depth of the range; access being had to the front ends of said ovens by doors 26 carried by the wall 3. The oven walls are in spaced relation to the walls of the range structure so as to provide top iiues 27 under the cooking tops 6;' end iiues 28 ;k bottom tlues 29, and battle fines 30, said batie lues being between the baking ovens and the ash pit 23 of the combustion chamber.` The innermost walls of the baking ovens 25 are carried downwardly to join the base'or range bottom 1 for approximately half the depth oitl the range, as best shownin Fig. 6, thus leaving openings 3i at the front side of the range establishing communication between the flues 29 and 30. In the baffleflues 30 are bailles or deflectors 32 and 33, the former extending upwardly Jfrom the base or range bottom 1 in the middle portion of the baflie flue7 and the latter' extending downwardly yfrom the top ot the battle flue to a vpoint between the baiiie 32 and the rear wall 5, said wall having an opening 34 at the rear end of each baliie flue. lt is now apparent that any warm air followingthe direction of the arrows showny in. Fig-1, aboutthe baking ovens 25,

must pass through the openings 31 upwardly into the battle liues 30, over the bailles 32, under the batlies 33, and outwardly through the openings 34. The battles within the baiiie Hue tend to retard the progress or exhaust of heated air and thus insure a uniform temperature about the oven walls.

The baille iiues 30 have inclined top walls 35 and the water jackets 17 have inclined bottom walls 37, said walls cooperating with the front and rear walls of the range structure in providing passages 36 establishing communication between the top flues 27 and the combustion chamber direct-ly above the grate 22.

Mounted against the rear walls 5 and 11 is a casing 38 containing longitudinally*` disposed parallel partitions 39 which meet below an exhaust connection 40 o1 the casing, said partitions providing exhaust lues 41 and a down iiue 42. rlhe exhaust flues 41 communicate with the openings 34 of the baffle lues 30 and with openings 43 in the wall 11 below the horizontal partition 13, said openings, at times, establishing communication between the exhaust flues 41 and the upper portion of the combustionchamber.

rlfhe down iiue 42 has its lower end communicatingy with an opening 44 in the rear wall 5, said opening communicating with the ash pit 23. rlhe upper end of the down flue communicates with the combustion chamberthrough ali-opening 45 in the wall 5 and extending through the opening 45 is a cold air inlet pipe 46y having its front end supported by the wall 9 and communica-ting with the atmosphere by means of a damper or shutter 47. The rear end of the cold air inlet pipe 46-extends downwardly in the down flue 42 and air entering the down iiue from the pipe' 46 is adapted to produce a siphonic action at the openingv 45 and draw oit any smoke, gases or unconsumed products of combustion from the combustion chamber. Such smoke and gases enters the ash pit 23, passes upwardly through the grate 22 and are burned by the bed of lire on the grate. Such gases as are not burned become heated and passl around the baking ovens 25 to eventually entery the exhaust flues 41 and the outlet connection 40 of the casing 38.

ln the cold airinlet pipe 46y or adjacent the opening 45, is a damper 43 on i damper rod 49 suitably mounted in the chamber wall 16 and one of the walls 10 so e The 'Vall 9 has a suitable door 51 below the oven door l5 and the door 5l permits of the upper portion or magazine off the combustion chamber being loaded with yfuel, for instance to the height indicated by the broken'line in Fig. 1. The tire ybed will be maintained above the grate 22 andy partly in the passages 36, as indicated by broken lines in said passages and consequently an intense heat will be in the top lues below the cooking tops 6. It will be noted that the bottoni walls 37 of the water jackets 17 are subjected to such heat.

When fuel is to be placed in the combustion chamber the dampers 50 are opened and consequently the damper 48 isv closed. Since the door 5l will be opened a draft will be produced rearwardly in the combus tion chamber to carry smoke and gases into the exhaust lues 4l, instead of through the opening 45 into the down flue, there being no siphonic action'because the damper 48 is closed. This is only during the tiring of a stove and after the door 5l is closed the damper 48 vmay be opened, so that unburned gases or fumes will bev directed' downwardly into the ash pit to pass through the bed of fire and be substantially consumed.

For fear that soot and other matter may accumulate in the lower ends of the iiues 4l and 42 the casing 38 is provided with doors 52 that may be opened and the lues cleaned out.

It is thought that the operation and utility of the cooking range will be apparent without further description, and while in the drawings there is illustrated a preferred embodiment of my invention, it is to be understood that the structural elements are susceptible to such variations and modifications as :tall within the scope of the appended claims.
