Speci'cation of Letters Patent.

A.applcaton filed July 3, 1915. Serial No. 38,036.

To all 'whom it may concern.'

Be it known that l, WILLIAM J. STAFFORD, a citizen of the United States, and resident of Quincy, Illinois, have invented certain new and useful Improvements in Stoves and Ranges, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming al part hereof.

ovens to be heated and hence on to the food to be cooked or baked; this is highly unde- My invention relates to improvements in stoves and ranges, particularly the type known as combination Vstoves and rangesin which either coal or gascan be utilized for producing heat.

The conventional stove ofthis type has the burners located in the base of the oven with the result that a smaller part of the base is operative when the heat is being supplied by the coal, and the productsl of combustion find their way Ainto the ovens owing to the contracting or expanding or warping of the surfaces betweenthe burners and the oven base. F urthermor in the stoves the market today, products-.of combustion of the gas burners pass into the sirable. In some other stoves now on the market, baiiie plates are placed in the ovens when gas is the fuel; this materially lowers the space efliciency of the oven.

My device obviates. all of these dliiiculities, in that the burners or source of heat A are located on thenoutside of the oven in a recess between the oven and the ash-pit in such a manner as not toobstruct the lines .around the oven when coal is the fuel and to distribute the heat as evenly as possible between the' yflues around the oven. No

baille plates are used, the stove being inl preparation for either coal or gas fuel at all times.

'- With the abovepurposes in view, my in-y vention consists in certain novel features of construction and arrangements of parts, as will be hereinafter more fully described pointed out in the claims and illustrated by ythe accompanying drawings in which- Figure 1 is a longitudinal sectional elevation through the center of the range. Fig. 2is a section along the line 2-2 of Fig. 1. Fig. 3 is an enlarged detail 'elevation of the burners shown in Fig. 1.

In the drawings numeral 4 designates the base plate and 5 the legs of the range. Mounted on the base plate 4 is positioned "dle or knob 25.

l Flue 15 is blocked or 1 the heat originates the -direction of the arrow passes-throughv the conventional oven 6, and the coal pouch 7 immediately over the ash pit 8. Between the vcoal pouch 7 and the ash pit 8 is positioned the rockerr grate 9. The gas plates 10 are secured to the oven 6 by the web 11. Oven 6 is enveloped by the iiues 12-13- 14415; 16 designates the conventional stack.

The wall 17 separating iue 15 from the coal pouch 7 and ash lpit Sis offset at 18 by the walls 19 and 20, leaving' a spaceA 21 .into which the burners 22 and 23 are placed. When the burners 22 and 23 are in the position shown in Fig. 1 the flue 15 is unobratentea new. re, reis.

structed. About the center 24 of burner 22' The rotation of these burners is broughtabout by the rotation of the extended han- The rotatability of these burners makes possi-ble a more even distribution of the heat 23, when in the horizontal position (asit must always be when gas is used) lies at thev 27 at its upper extremity. Furthermore this positioning of the burners (the horizontal) prevents the heat from'concentrating in the space 21, possibly burningn-tlie A walls 19 and 20, and operating at a lowveiliciency. When coal is the fuel, the burners are placed "in the position shown in Fig. 1, in theA pouch 7 and in lues 12-13114 and then through a bailed pa'th (not shown) under the oven to the rear and up the stack 16. l VYhen gas is the fuel the heated gases pass from the burner 22, up the blocked flue 15, on one side of the ven, and through lues 1 .4- -`13-12 and stack 16 on the remaining sides of the oven. ,l

28 designates a flue vclean o'ut.- 29 designates air Aholes 4intothe space 21 from the bottomfzth'e rang'. y

The burners can madeto remain stain the iues because burnerof air up the flue 15.` restricted by the plate tionary in the position shown in Fig. l.: When so made a damper 30, rotatable about' a point 3l is so positloned that in the position shown by full lines in Fig. l the space 21 is sealed from -the flues 14 and 15. The `utility of this positioning of the damper resides in the fact that when coal is the fuel,

air is precluded from entering the iues L14 It will be discerned that by these means, the

objects stated elsewhere in this specification are accomplished. .i

What I claim is:

` l. In a device of the character described,

ovens, Hues, said fines surrounding said ovens, an offset at the juncture of two said y ues, a 'source of heat rotatively secured in said offset, so that in certain positions of said source of heat, the fines will be unobstructed while in other positions one portion of said source of heat will be at the en- Copes ot this. patent may be obtained for trance to one of said flues and another por- 'I tion of said source of heat will be at the env{'luesga source'tf heat consisting of two hollow members of circular cross section rotatively secured at the geometric cross sectional centers at the extremities of one of the members so that in certain positions of :laid source of heat, the ues will be unobstructed while in other positions one member of said source of heat will be at the entrance to one of said lues and another melnber of said source of heat will be at the entrance to another of said flues.

In testimony whereof, I have'signed my name to this specification, in presence of two subscribing witnesses.
