To all whomtt may concern:

B e it known that l, WILLiAM A. MILLS, a citizen of the United Sjates, residing at Portv Chester, in the de unty oft-Westchester and Stateof New York, have i invented an Improvement'in Gas-Ranges, of which theffollowing is a specification.

In gas ranges it is desirable to View the'fburners and to be able to light thesame from the front of the rangebe'cause it isalways necessary to exercise-great care .l-4 -in the use of .gas ranges to avoidan explosion of a lmixture of gas and air, especially' in the oven. To this endf devices have b'een` employed which advanta geously reqhire thatthe oven door be opened before 'the burners caribe lighted; this permitting the said 4`1{i mixture to escape andy consequently avoidingtle/e plosie'n. v ,Gaslranges have heretofore been made where it was first necessary to open the oven door, but 1n these devices feithe'r the burners couldnot be viewed or the v2 9 oven bottom 'had to be raised to view and light the f burners, both of 'which conditions have their apparent disadvantages.V `My inventionrelates to a gas range'where the oven 'door'must be opened before the burnerscan be lighted 2 5 jor viewed and Vthe' samegis especially applicable `to a y .gas range' having an-oven and achamber beneath the eamein'gfwhich the burners arelocated, said lower chamber being separated. from the 'oven by. the oven #other iny which 'case both the oven.and the broiling "'chamber areprovided with doors,'the'burners being 'el in the'bminng. chamber; f j

In @anyingout'my invention, the division plate extending across the front of the range between the oven :l5-@amd the broilingchamber is reduced in width between the'sideplates'o the'range so as to provide an opening lfthrough which the burners can be viewed when theV oven' door isvopenfand into which opening the flame convyer ortconveyers from the burner or burners ap 4 0 pear 'conveniently .for theapplication of a match for lighting the burners.,V The opening thereby created fis closed over when the oven door is shut. ,.-Iu'thedrawing, I have represented a. gas range having abroiling chamber and'iin ,which j Figure is apartial front elevation of the gas range zshowingfzthe, lower portion of the oven door broken away-,'Fig-.-2 is a partial vertical section of a burner and" Haine c onveyer leadingto the aperture between thedivision 'plateand oven bottom, which latter withl 515D aparts ef the 'doors are 'shown in section, Fig.A 3 is a cletacl'iedse'ction similar to Fig. 2, with the oven door re moved and Fig. 4' is anelevation of the lower inner edgeof the oven door.

This portion had been cut away so as to leave an opening 2 below the oven bottom or plate 3 extending the entire length of theoven and into which the or'ce or -mouth of the flame conveyer f extends,vand bythe apbottom, as a support'ior articles of food being cooked. bottom. The lowenchamber may be a broiling cham- A The oven door c has its lower edge prolonged seas to come below the opening 2 and close against the upper edge of the plate a and the upperfedgeof the door of the broiling chamber comes against the lower edge o' said plate, and when the oven door is shut the opening ,2- does not appear and it is necessary to open the oven door before the burners can be lighted, consequently `should anymixture of gasiand air escape from the burners and get into the oven there is a chance for their The division plate a at its lower edge is covered over vdivision plate is made narrow, asy if the usual upper l escape when the oven door is opened and before the burners are lighted, thus 'reducing to-a minimum the risk of explosion. lurthermore, I have lshown and -prefer to employ a projection or plate 7 cast with the shut, 'both the opening 2 and the orifice or mouth 6 o the iame conveyer are closed off. This position of the door and plate 7 prevents the' escape of anyjof the mixture' of gas and air from the burners orflame conveyer into the oven before the door is opened and also prevents hea'ted air passing through the opening 2 during the baking operation as this wouldnnevenly heat the oven, an even or uniiorm heating being. effected on all sides of the ovennwhen the opening 2 is entirely closed off In the device of my invention the burnerscan be very easily'fiewed through thev opening y2 without stooping sufficiently low to look into the broiling chamber and without'the trouble of'opening the door of the broiling chamber. p

" I lclaim as Inyinvention:

It will be apparent from Fig. '2, that each llame conveyer is made with downward and upward projections* the lower of which rests' upon the in-turned edge of thel division plate and the upper of which-comes beneath the oven 'bottom assisting in supporting the same.
