Application filed September 23, 1922. Serial No. 589,962.

To all whom t may concern:

Be it known, that I, JOHN J. TooMnY, a citizen of the United States, residing at Chicago7 in thev county of Cook and State of Illinois. having invented certain newand useful Improvements in Ranges7 do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings.

The invention. relates to ranges used for domestic cooking' purposes, and its object is to provide an improved range in which a duplex-fuel cooking-top section and an oven section are respectively7 constructed in unitary organizations adapted to be interchangeably mounted on the same base, so that the saine parts may be set up and utilized as either a right-hand or a left-hand oveny duplex range.

The invention consists in the matters hereinafter described and then pointed out in the appended claims. A

In the laccompanying drawings which illustrate embodiments 'of my invention, Fig. l is a. front view of a range exemplifying -my invention organized with a right-hand oven and a left-hand duplex-fuel cookingtop; Fig. 2 is a similar view of a range with the same parts organized with a lefthand oven and a right-hand duplex-fuel cooking-top Fig.f3 is a view partlyy in Afront elevation and partly in cross-section on the line 3 3 in Fig. 4; Fig. 4L is a longitudinal sectional View on the line 4:-4 in Fig. 3; Fig. 5 is a detail view on the line 5 5 in Fig. l showing the y'reversible gas-manifold and its gas-burner valves in their twopositions in full and dotted lines respectively; Fig. 6 is a detail view of the gas-manifold with one of the burner valves shown in its two positions vthereon in full and dotted lines respectively; Fig. 7 is atop plan view of the base; Fig. 8 is a bottom plan view of the duplex-fuel cooking-top section inverted with the gas-burners shown in dotted lines;

Fig. 9 is a similar view of the oven section` inverted, and Figs. l()7 1l, and l2 are detail VIGVS.

The oven section 3 is constructed and organized as unit, and. comprises a suitable metallic body having top, side andA rear walls.I a metalv bottom plate 4 and a castmetal front frame 5, providing an upper baking oven and a lower broiling or toasting oven. which are separated from each other by thel usual removable sheet-metal partition (not sho-wn) arranged above thecenter` heat oven burner, and are provided with doors 6 and 7, respectively,v whosejfram'es are suitably hinged on appropriateportions of the front frame All these parts are organized to comprise an oven unit which@ is capable of being bodily attached to and detached from the supporting base; in vthe r'orm shown. this cabinet or oven unit is secured to the base by suitable removable bolts 8 arranged at the front andk rearfof" its bottom plate and "enteringboltholes 9 arranged in sets of four on opposite sides of the center of the front an'd rear railsot` the base, as shown in `Fig.,7, sothat'the oven-section can be mounted'at eitherfendl havingI a. di'flerent type of heating-units,

preferably gaseburners. The solid-fuel portion comprises an'ash-pitlO and a lire-box ll of usual rectangular form and assembled together in any suitable manner and having aV cast-metal iront frame l2 secured thereto` provided with the usual opening in its lbwer portion to afford access to the interior,.the door 13 'for this opening being hingedv to the iframe l2. The ash-pit is vprovided with the usual grate-bars 14 and ash-pan 151, and the fire-box has the usual rear outlet 16 p'rovided with an elbow 17 to connect with the "line-,pipe 18, and may have suitable inlet and outlet passages for a hotwater coil 19. The re-box has a cast-metal rectangular top 2O bolted to it and provided with the usual yshort-center 2l and a pair of standardsolidltu'el cooking openings closed by klids 22. The cast aslrpit bottom is secured to the base l by removable bolts 24: arranged at its front and rear and entering bolt holes inthe .front and rear rails ofthe base; they outer lateral pair oit bolts 24- entjer the outer lateral pair of holes 9. and the innerv lateral pair of boltsf2l enter holes arranged in op'- pos'ite pairs 25 and 26, in the front andrea'r rails of the base, according as the section 2 is mounted atthe right or left hand end' of the base, the holes 25 and 26 being spaced inwardly or' along the length` of the base from the outer holes 9 in correspondence with the spacing of the front and rear-bolts 24 from each other. The front frame 12 is provided with loiver ears27 which are bolted to the base, the latter being provided at each end with a pair of bolt holes 23 and 29, respectively, the holes of each pair being spaced apart to register With vthe ears 2 when the section 2 is assembled on the corresponding end of the base The section 2 is lprovided with a main top `,composed of a front rail 30, rear rail 31 and end'rails 32, all preferably castintegral; the front and rear rails extend laterally at each side beyond thehre pot, as shown `in Fig., S, so that with the end rails 32 they form the tops of the burner-boxes on opposite sides of the fire-box. The front and rear rails of the main top are provided With inwardly eX- tending depressed flanges to vseat the ends of the nre-box top 20 and the ends and outer sides of the usual burner-boi; top grates or grids 33 flush therewith, and the sides of 31 seats on the'rear end of the lire-box.

"the top 20 are similarly constructed to seat the inner sides of the grids from front' to rear. The front rail 30 is bolted to the upper end of the frame 12. and the rear rail The frame of the cooking-top unit 2 is thus composed of the front-frame12 of the solid-fuel portion and the main top of the burner-box, and is'secured to the front rail of the base vl by the e'ars 27. The rear rail 31 of the main top is secured to the rear rail of the base by a pair of angular-ly disposed braces 34; the upper ends of these braces are bolted Ato the rail 31 nearv its outer ends, and their lower ends are dctachably bolted to the base-rail near its end corresponding to the right or left hand location ofthe unit 2 onthe base, for Which purpose the latter is provided with bolt-holes arranged in end pairs 35 and 36 as sho-Wn in Fig. 7, the holes of each pair being spaced apart on each side of the center line of the ash-pit when the latter is mounted above them as shown in Fig. 3. By this construction the braces for the main top are secured interchangeably in the holes 35 and 36 when the section 2 is reversely mounted in position at the corresponding end of the base.

lThe section 2 is provided with a sectional v:bythe bolts 24, ears 27 and braces 34. Fach section of the burner-box is rectangular and formed with sheet-metal side Walls 33, bottom'39 and rear wall 40, the latter having a .series of air. inlets 4l as shown in Fig. 3;

these parts are suitably secured to the fireboX and main top, andv each section is open at its front and has an L-shaped cast-metal leg 43 is secured to the side rail 32 of the main top, the parts being arranged With the 'burner-box spaced above the base and approximately in line with the upper portion of the broiler oven so that the burners 37 are in the horizontal plane ofthe oven burner 44, as shown for examplel in Figs'. yl and 2. The burners 37 comp-rise the usual giant burner and three regulation burners to afford the standard top-cooking capacity of the commercial gas-range; a simmering' burner 37 may be used, and all the burners are o-f the usual blue-flame type having integral air-mixers as indicated in Figs. l andL 2. At the fron-t of the burner-box andof the oven unita gas-supply manifold 45 is reversibly mounted for supplying all the burners; it is provided with a valve 46 for the oven-burner and Withl two pairs of valves 47 and 43, respectively. for the burner-box burners; The manifold has an angular threaded supply pipe'49 constructed to pass back throughthe burner-box and out through the outer passage 4l in the rear M ivall thereo-f. so that the pipe 49 can pass through either The manifold is reversible end opening 4l, and ea'ch of the valves is rei versible onL the manifold so that it can be fold itself is reversed; As shownin Fig. 1 the manifold is mounted for a 4left-hand burner-box, With its pipe 49 passingthrough 'given a half-turn thereon tvhen the mani# lill) the left-hand passage 41 of Fig. 3. and inv i 447 and there valves and the manifold are disposedias shoivn in full lines in Figjl, their jcts'noiv being in register with the airmixtures of the burners as shown in Fig. 1.k On the other hand, When the burner-boxis mounted at thel right-hand end of the base'- as shown in Fig. 27the manifold is detached from its full-line position shown in Figs.

`1 and and is turned over end on end and 'mounted inthe position shown in Fig. 2

and in dotted lines in Fig. 5 Wit-hits supply pipe 49 passing through the right-hand passage 41 of Fig. 3, thus .bringing the valve 46 at the burner 44 the valves 47 at thek burners 37 of the left-hand burner-box 'section and the valves Y43 at the burners 37 of the right-hand section thereof as shown in F ig. 2 and in dotted lines in Fig. 5i their jets noul being in registerivith the air- .A mixers. of the burners as 'sh-own in Fig, 2. Each valve is mounted on the manifold so free end of the manifold is closed by a cap 50, and suitable brackets 5l and 52 are provided respectively on the front rail 30 of the main top and on the frame 5 of the oven,

to detachably Vsupport the manifold; in practice these brackets are composed of separable portions which are suitably carried on the frame 5 and rail 30 and are clamped around the manifold tol securely hold it in either of its positions. Fig. l0 shows a detail of the bracket 5l in which the hanger 53 is bolted to the front rail 30 and projects forward into the line of the manifold, and the clamp 54 is detachably secured by a bolt 55 on the hanger 53, the manifold being held between their curved outer ends. Fig. ll shows a detail of bracket '52 in which eachV of the opposite parts 56 and 5T has marginal spacing flanges and a central inner lug 58 adapted to enter a hole in a projection 59 cast on the front of the frame 5, and these parts are locked in position on the .lug by a bolt 60, the manifold being held between their forwardly projecting'outer ends. To reverse the manifold it is only necessary to remove. the three top pieces of these brackets.

The duplex-fuel section visprovided with an upright rear splasher or back guard 6l having al shelf 62, and a reversible' end bracket 63 having flanges 64 and 65 at its opposite ends by which it attached to one of the side rails 32 o f the main top and to the shelf 62, this bracket ybeing reversed or turned end on'end when it is assembled respectively ou a right or left hand burnerbox as shown in Figs. 2 and l.

The duplex-fuel section carries a reversible end panel 66 which is angular in contour and carries pairs of lugs 67 and '68 on its adjacent edges by which it is interchangeably bolted to the frame l2 and a leg 42 of the burner-box frame, which are provided with suitable holes 69 and 70, respectively. The panel is thus reversible to fit either side of the stove as shown in Figs. l and 2, being given a quarter turn to reverse its position. There is a space below the inner burner-box section and between the coal-heater and the oven in either position of the two units which forms a warming chamber 71; a removable plate 72 closes the bottom of this chamber in either relation of the units,iand its rear end is closed by a suitable panel (not shown). The lire-pot forms one side of this chamber 7l and being exposed radiates considerable heat, so that the chamber is properly warmed in either position of the units. `When the range is to be used with the oven located at the right-hand side asin Fig. l, the oven orcabinet unit is mounted on the right-hand end of the base with its bolts 8 in` engagement with the right-hand set of four bolt-holes 9 in the base shown in F ig.7, and the duplex-fuel cooking-top unit is mounted on the left-hand end of the base with the bolts 24 of its solid-fuel portion in engagement with the bolt-holes 26 and the outer' lateral holes of the left-hand lset 9; the braces 34 engage the holes 35, and the ears 27 of the front-frame are bolted to the base at 29. lVhen the range-is lto be used with the oven located at its left-hand side as in Fig. 2, the oven or'cabinet unit is mounted on the left-hand end of the base with itsbolts S in engagement .with the llefthand set of four bolt-holes 9 in the base shown in Fig. 7, and the cooking-top `unit is mounted on the right-hand end of the basewith its bolts 24 in engagement with the boltholes 25and the outer lateral holes of the right-hand set'9; the braces 34 engage the holes 36, and the ears 27are bolted to the y base at 28. ln either casefthe other parts are assembled as disclosed and a complete range having standardoven equipment and a duplex-fuel cooking-'top of standard r'ca-- pacity for both kinds of fuel'isfprovided.

` By -organizingfthe duplex-.fuel unit with the solid-fuel portion betweenthesections of the open-front burner-boxandconstruct-ed to be supported at its lower end on the base, it is possible to place this unit tlush'against eitherl a rightor left hand oven similarly supported on the base and so to standardize the units for" interchangeabley relation and enable the duplex-fuel range to be changed from a right to a lefthand oven and vice versa without using any eXtra parts, and in either case the gas burners in the burnerboXes are in line with the oven burner and all the burners and the hard-fuel heater can be used at the same time and a warming chamber is provided. This interchangeable feature is important and advantageous to the manufacturer, the dealer and the user.r By my invention the manufacturer is required to make and carry in stock only a single supply or line for both right and left hand oven duplex-fuel ranges' and can dispense with the expensive duplicate patterns, molds and operations required for the different kinds; all his appliances and operations are standardized and limited to a single line or type, and all his supply can' be mountedl and shipped out in either form or in both forms as desired. Also, the dealer or .retail merchant need not carry separate stocks of `right and left oven duplex-fuel ranges,.but can limit hisstock to a single line and can lill orders from users for either right or left oven ranges. Further, the user can utilize Jthe same du plex-fuel range in kitchens where the plan or equipment makes itdesirable to have either a right or lett oven range set in one or another particular location; the range can be appropriately set up without requiring an exchange or the purchase of additional parts. Also, considerable floor space is saved as my range can be set with its cooking 'top against a wall of the kitchen as the outer burner-box section spaces the tire-box far enough from the wall to prevent damage; and the fire-box is exposed all around and permits the heat to radiate from both its sides, so that the hard-fuel section is doubly serviceable for heating the kitchen, and a warming-chamber is provided in either arrangement of the sections. -By my invention the duplex-fuel range. can be set with its cooking top end against the wall to save floor space, and it affords radiation of heat on both sides of the hard-fuel portion, and' a complete duplex-fuel cooking range and kitchen heater reversible for either right or left hand oven is provided as one unit.

The gas burners are merely typical of a convenient form of heating unit for the cooking top and the ovens, as these parts may have heaters of any suitable type, as for example by placing electric heating units where the gas-heating units are shown.

This application is a continuation in part of my `co-pending application filed July 2,v

1921, bearing Serial Number 482,130.
