WILLIIVI J. lBEST, OF Dllfll'F MICHIGAN.

OVEN.

To all whom 'itmy concern: A

Be it known that l, WILLIAM J; BEST, a ycitizen of the United States, and ares'ident of Detroit, in the county of llVayne and State of Michigan, have invented a new and Improved Oven, of which the following is a specificati-ion.

This invention relates to' gas ranges and its objectis to provide a range oven so constructed that the heated air and productsA of coinbustionare admitted thereto in practieally'the vSame quantity. and proportion through' both sides and escape therefrom r in practically the saine" proportion through openings at the yback and front ofthe bot,-

-tom, thus insuring a practically even teinperature throughout the oven and giving InV the accompanying drawing, Figure 1 is agfront elevation of a= gas range embody# ing this invention.v Fig. 2 isa vertical trans verse section o n the line 2 2 of Fig.

F 3 is a vertical longitudinal sectionon the lineS-,f of 'Fig'. 2.` Fig. 4 is a horizontal longitudinal section on t-he line 4 4: of Fig. 42. Fig. 5 is a vertical transverse sec tion on tlie'line of Fig. 4. Fig. is a partial horizontal transverse section of a range slightly different. in details 'of ennstin'ctioii fronfthztt shown in Fig. 4. Fig. 7

is a vertical Y'cioss"section on the lineff'HT of Fig. 5. f

Similar reference characters refer `to like parts throughout. the severalv views.

The drawing shows a range' having the well knowntop 1 'andfiiel pipe As' this fuel-pipe forms no part of this invention it is omitted in all but Fig. 1. ln thisspecitication the exterior shellv will be tei-ined the ,casing and the interior shelLwill, betermed the oven. The casing is formed of aback 3,' sides et and 5, a bottoni 6, and front 7 'The top 1 is preferably supportediby theback and sides ofthe casing. `The oven has'a top 8,

preferably of'several 'thicknesses' of sheet metal separated by a'sheet of asbestos or other 'poor heat coi'ducting material, and the

casing sides

4 and 5 are preferably similarly formed. rThe back 9 ofthe oven is -separated from the back of the casing and connects toits sides and bottoni. Plates 10 extend from the bottom ofthe casing to the. side edges of the oven bottom 11, which specification of Lener raient.

has perforations 12 near its back and front for the-escape of the heating medium.

Extendingbetween the front 7 of the casing and back plate 9 of the oven to forni the sides of the oven are plates 11 and 15, having inwardly extending

flanges

16 and 17, to support racks or plates to receive the food to be cooked. Between the plates and the sides of the casing are delict-.tor plates 18, preferably formed with down turned flanges 19. The front Iplate of the casing joins the'top and bottom of the oven, and the opening in this plate is normally closed by the door 2O.y which may be provided with a glass plate 21. K

Extending into the space below the. oven is a fuel pipe 23 having branches 21 which' connect to t-lie rearwardly extendingl burner tubes 25 near the bottoms of the side fines. Small windows 26 in the front admitof the burning of the gas being observed. Air for the burners can enter through openings in the bottom of the easing shown in `Fig. 2.A

The operation of the oven is as follows. rllhe burners being lighted and the door closed. the heated air and products of combustion will pass upward` a pnrtion strikingy against the plates 1S and beine; deflected inwzirdlv between the bottoni plate Ll of the 'ouen and the flange 1T at each side. The other portion will pass up and into the oven` a portion through between the

plates

14 and 15 and t/he remainder abovethe plates 14. lThe hot. gases which enter below thc detlector plates 1S will canse eddies in the oven, resulting` in an even temperature. '.lho gases finally escape through the. holes l2 in the bottoni plate and enter the space below ythe oven. A pipe 2Q extends into this space `and has an inlet openingpreferablyr in its upper side and' preferably near the middle of the bottoni of the oven. The gases will therefore pass in practically equal quantiities through the holes 12 at the back and at "of one plate 18 at each side over the burner.

type of grating may be employed. I Instead tubes 25, 'a plurality of plates Oamay be employed as shown in Fig. 6. Many other changes in the details of construction may be made by those skilled in the art Without departingfrom the spirit ofv my invention. Having now explained my improvements, what. I claim as my. invention and desire to secure by Letters Patent is 1. The combination of a casing, anoven Within the casing and spaced therefrom,

said oven having perforations in its bottom near each end, a door forming the front of the oren, the sides of the oven having longitudinal openings toadmit the products ot combustion, burners 'at the lower edges of the sides ot' the oven, deflector plates positioned over the burners to cause a portion of the products of combustion to enter the loren at the bottoms of its` sides, and a pipe extending to the middle of the bottom of -the oven to carry away the products of combustion which escape yfrom the oven through sides of the oren having openings near the bottom and top, and delector plates mount-v ed above the openings near the bottom of the oven and having down-turned edges to compel a portion of the products of combustion to enter the oven near its bottom.

4. 'lhe combination of a casing, an oven within the casing and spaced therefrom at its sides, burners at the bottom of the spaces between the sides of the oven and casing, the sides of the oven having openings at the bottom of the oven and above the same, dtiector plates of less length than said oven extending between the sides of the oven and the casingjust above the lower openings to compel a portion of thelproduots of combustion to enter the oven at the bottom and permitting the remainder to ascend and enter through the upper openings.

In testimonyY whereof, I have signed this specication in the presence of two subscribing witnesses. l
