COMBINATION COAL AND GAS RANGE.

' Specification of Letters Patent. Patented June 26, 1917.

Application filed October 11, 1916. Serial No. 125,023.

To all whom-it may concern: u

Be it knownthat I, MAX R. LEHMAN, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful .Im rovements in Combination Coal anges, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to-certain new and useful improvements in combination coal and gas ranges, the object of the intention being to provide a range in which the oven thereof is provided with. a continuous burner chamber extending around three 0'!"- its sides beneath the bottom thereof into 'which'j'can be quickly inserted or removed therefrom a substantially U-shaped burner, the legs of which extend into the burner chambers formed on the sides of the oven insnch a manner that the hot air and prod uctsbf'c'ombustion rising from the burner will be distributed equally within the oven.

' Another object of my invention is to pro vide a constpu'ctionof range in which the usual form of oven which is surrounded by the ordinary coa fines is not changed to any extent,'the bottom dhieof the range being formed. with burner chambers to receive the burnei'ygsaid burner: chambers communicating with the lower portion of the oven 'througlf thje medium of gratings Anothenobje'ctof my invention is to provide'a combination coal andgas range with an ovenhavinga vent in-the top thereof for the 'e'scapcflofthe' hot air and products of combustion which is protected by a baffle so astozpreveirt the'products of combustion *rising from the ffire boxf when the stove is being used as a; coal stove from passing into the "oven,

Another object of the invention is to provjde theburner chambers with air inlets so astoobtain the proper combustion and to supply air freely to the burners so that the hot an. and products of combustion will be conveyed through the oven in order to enable the oven to bake quickl Z Other and further ob]ects and advantages of the invention will be hereinafterset; forth and the novel features-thereof defined by the appended claims. 1

In the drawings,

Figurel is alongitudinal vertical section Fig. 5 is a detail perspective view of a portion of a casingof the stove showing the construction of a stove at the right ban corner in order to enable the burner to be inserted within the burner chambers; and

Fig. 6 is a section taken on. the line 6-6 of Fig. 3. l

In carrying out my invention I employ a stove having the usual firebox 1, ash-pit 2 and oven chamber 3 which is surrounded by the ordinary coal fiues in order to' enable the products ofcombustion'from the firebox to circulate around the oven in. the 'or dinary manner as stoves of this character now in use. The top of the stove is preferably provided with a foraminated portion 4 under which are adapted to be placed burners not shown. The oven chamber?) has vent openings 5 formed in the top thereoi for allowing the products of combustion entering the oven from the burning chamber to circulate through and around the same when the dampers have been adjusted, the

construction of dampers forming no part i of this invention.

Arranged over the outlet vents '5 of the oven is a baffle 6 for preventing the products of combustion rising from the fire-box 2 from entering the oven when the stove is being used as a coal stove, and ior deflecting the escaping products of combustion and hot air toward the side 'flues. Arranged beneath theoven chamber 3 are side burner chambers 7 and 8' which communicat with a front burner. chamber 9 in order to form a continuous substantially U- shaped burner chamber extending around the two sides and front of the oven as clearly shoWnin Fig. 3. '1'

The side burner chamber 7 is formed by a housing and communicates with the oven chamber" through a grating 10 which can be readily] removed, the bottom of the cham-' her being provided with air inlets 11 and th end of the chamber'is'provided with air inlets 12 at the back ofthe stove in order tothe burners which to supply air freel will be hereinafter ully described.

, and securin The side burner chamber 8 is formed by cutting away the lower corner of the oven thereto a substantially U- shapedhousing, said housing communicatin withthe oven chamber through a removable grating 13/ The chamber 8 extends to the rear of the stove and is provided with air inlets 8.-

A .front bu1'ner' chamber 9 is formed by cutting oil a portion of the bottom. flue by arranging a longitudinally disposed ob-' hquely arranged plate therein, and the top of the burnerchamber 9 is closed by a rating 14 and the chamber is provided wit air in ets .15 beneath the oven door. 4

The lower corner of the side flue of the stove at'the'front of the same is cut away and a casing 16 is inserted in the cut-away portions-forming a passageway which communicates with the end of the front burner chamber "9 and. is of sucha size thatthe mixing" bell 17 of my improved construction of burner 18 can be readily forced through the same when the gratings are re move and the oven door is in open position. M im roved construction of burner 1-8 is substantially U-shaped as shown hav ing branches 19 and 20 adapted to extend into the side burner chambers 7 and 8 the burner] being preferably, formed of piping chambers with the having perforations or cuts, 35

seen that I have provided a stove in which;

From the foregoingdescription it will be the oven has burner chambers commumcating with 1 the lower portion thereof along two of its sides and the front thereof, which chambers are closed by removable gratings which when removed. form a substantially U-shaped burner chamber intowhich extends an opening from the outside of the stove to receive the intake of the burner, said intake having a mixing bell. to receive a valve controlled-gas supply pipe.

In order to insert my improved construction ,of burner into astove' as herein shown and described, the gratings covering the burnerchambers are removed and the burner 18 isplaced into the oven and canted so that the bell 17 can be-forced outwardly through the opening 16 and the body portion and branches 19 and 20 of th burner canthen be dropped into position within the side and front burner chambers, andby covering the be protected.

When the burner is in position within the burnerchambers of the stove, air is supplied f freely to the burner chambers through the air inlets 11, 12, 15 and 8 which. causes a circulation of the hot air andproducts of combustion through'th ovento pass out of the vents 5 into the fines of the stove and gratings the burners will around the oven so as to thoroughly heat the same.
