cooKING- s'rovn i useful Improvements in Cooking-Stoves, of

which the following is a specification. l

My invention relates to improvements 1n cooking stovesand it consists 1n the combinations, constructions and ,arrangements herein described and claimed.

An object of my invention is to provide` a device for cooking purposes which will make use of either solid or gaseous fuel with?. means for protecting the gas burners lwhen solid fuel is used. with the device.

further object of my invention is to provide a device in which the change from a solid fuel stove to one which uses gaseous fuel may be quickly and easily made.

A furthergobject of my invention is to provide a combined stove in which the prod'- ucts of combustion of the solid fuel and those of the gaseous fuel are made to take a tortuous path around ovens thereby heating the latter and economizing in the use of fuel due to the fact that a greater proportgion of heat is abstracted from the prodnets of combustion during their travel than in the ordinary" stove.

i@ther objects and advantages will appear in the following speciication and the novel features of the device will be particularly lpointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming part of this application in which- Figure 1 isa perspective view of the stove, Fig. 2 is a view of a portion of one of the ovens showing the damper, Fig. 3 is a section through one of the-ovens, Fig. 4 is a.

section along the line 4-4 of Fi 3, Fig.

is vertical section through t e device along the line 5*-5 of Fig. 6, and Fig.'6 is a vertical section through the device along the line G- of Fig. 5.

In carrying out my invention I provide a casing l at one end of the device, containing a tire box 'or combustion chamber 2, a grate 3, and an ash pit el. Joining the top of the combustion chamber and extending to the opposite end of the stove is the lower wall 5 of the passage 6 for the products of combustion. The top wall of the stove 7 extends Specicaton of Letters Patent.

over the combustion chamber and the walls 5 and 7 are supported at one end of the stove Patented Oct. 5, 1915. Application filed July 3, 1.913. Serial No. 777,253.

by legs 8. At the rear of the stove isan up-V wardly .extending frame 10 having hinged brackets 11 bearing at its top a warming Upper andl lower ovens 13 is mounted o n the upper wall 7 of Athe stove. The walls of the casing 15 as well asthewall 5 arepreferably made double with some nonconductor of heat such' as asbestos packing disposedfbetween the two wall members.

The upper ovenl 13 is slidably supported on brackets 1391 and is movable into and out of the casing 1n the manner shown in Fig. 6.

The lower oven 14 is slidably supported on.

similar brackets 14a. The ovens are provided with hinged doors such as'th'ose shownv 'at 13b and 14"..

As will be seen from Fig. 5 openings 7X are provided in the upper wall 7 of the passage 6, these openings being situated in alinement with the space between the ovens and the casing 15. Between the ovens lgand 14C are inwardly extending baille 'plates 16 and above' the oven 13 is a. forwardly ex'- tendi'ng balle plate 17. An exit flue 18 is disposed at the rear of the upper part of the casing 15. Air inlets 19 are provided in the sides of the casing 15 near the bottom thereandvll; respectively are arranged withina casing 15 which f of, these air inlets being controlled by damf pers 20.

Referringnow particularly to Figs. 4 and` 5 it will be seen that I have provided a pair of gaseous fuel burners 21 and 22, which are directlyunderneath the stove openings normally covered by the lids 21X'and 22X respectively. These burners are' disposed in housings such as those shown at 21y and 22% carried b v the wall 5. Over each burner is disposed aplate23 which is pivotally connected with the wall 5 and is adapted tobe swung outof the way of the burner when the latter is used and to be swung over'the burner to protect the latter when the solid fuel is being used. These burners are fed' from a main pipe 24 extending in front of the stove and provided with branches 21Z and 22z'leading to the burners and controlled by stop kys 21k and 22k respeetively.` -The end of the pipe 24 communicates with .the pipe 25'which is controlled byal cock 25 Thev'pipe 25 in turn communicates with a los ce ue; thus hoiJ waiter may be pair of burners 26 sind 2'? disposed under Beuth the lower oven 14A These lim-ners :ire provided with side openings ./l :ind 2i".

From the foregoing description oi the miiolis parts oi" the device the opi'xreiion thereof may he readily understood.

When it is desired to use solid iiiiel with the Stove the plates 23 are swung; orer the burners 31 :ind 22, solid store lide like diese shown :it L8 :ire provided for the stove holes above the burners und the dzinipere il) nre closed. rllhe products oi' combustion in the fire box 2 pase inthe direction shown hy the iurowe in lo 1g. 5, thence up through ille openings 7*' nd around the ovens and lmiiie platee and thence out through the iie 1S. The provieion oi' the baille plates 16 and 17 tends to canse the products of Combustion to take a longer course and hence more oli the heating; power of Iche gases is utilized in the ovensy it Will. be noted that the combustion chamber 2' is provided with a. Waiter back 29 with which thejpipes 30 and 3l ooinn'iunisupplied. in the usual way.

@when the deif'iee is io be used es e gas stove the protecting plates, w are moved beek 'te expose ehehurners 21 and 22. rlfhe lids 213 and 22X ina/y be removed und the cooking may vbe done immediately ovei.` the mii-ners. wwhen it is deeireii to use the ovens 13 and 1.4i the huirners 26 and. ere ligiiiei and ille dempers :1re opened io permit *die 'eniianee of nir necessary for supporting combustion. The burners 2G sind 2T, Stated before, are pi'ovicled with openings on either side and hence when solid fuel is used with the stove ithese bilrnersnre not clogged up with soot und dirt ne tlfey would he if the burners had openings on their upper sides.

'it will he noted that :is fair :is the ovene are concerned the products of eoinhusiion teli-e 'the saine Course when the device i5 used es' a gais stove :is they do When'solid ifuel is; used. The plates 23 muy be moved verf.' quickly and thus the device may be Changed immediately roni n gas stove to one usingpr solid 'fuel of rice versa.

'I am :aware iz-lmt other .forme of the device based upon the same general plan might be made, hut l consider ne my own all eheh inodilieaions ne fairly i'zill within the epiiil; end the scope of the invention.
