For the purpose of illustrating the invention, the drawings show a gas stove or range supported on legs 11 and having a substantially rectangular base frame 12, shown in Fig. 1, supported on the legs 11. A combined broiler and oven portion 13 of usual construction is supported on the base frame 12 at an end of the range, providing as usual number of ovens 14 which are closed by suitable doors 15.

An open burner portion generallydesignated by the reference character 16 is supported on the base frame 12 adjacent the ovens 14 and extends to the end opposite the ovens. The burner portion 16 has a corner frame member 17 which is secured at its lower end to the base frame 12 by- 5 means of a bolt 18 and which projects vertically therefrom. The corner frame member 1'7 is substantially angle shaped, having a front leg 19 which is provided with a slot 21 intermediate its ends. The top end of the corner frame member 10 17 flares outwardly to provide an enlarged portion 22, as shown in Fig. 3. A corner frame member 23 co-operates with the corner frame member 17 to support the top of the burner portion 16 and is suitably secured to a side 24 of the broiler and 5 oven portion 13 and has the same sectional shape as the member 17. A front leg 25 0f the member 23 is cast to terminate above the lower end of the member 17, providing a recessed'or slotted portion 26 at its lower end to correspond with the 20 slot 21 in the member 17.

. The front faces 19 and 25 of the corner frame members are cast in the form of an arc which is provided with a ledge 27 arrangedalong the vertical inner edge of each of the members 17 25 and 23. The ledges 27 terminate at their lower ends in lugs 28 which are cast on the members 1'7 and 23 and which are offset behind the ledges 2,7- The lugs 28' have grooves 29 transversely of their upper ends to provide overhang- 30 ing projections 31 for each lug and extend downwardly to the upper, sides of the slot 21 and the corresponding cut-away portion 26 in the comer frame member 23. Slots 32 are provided in the lugs 28 and extend from the bottom upwardly to a point just below the transverse grooves 29 which provide the overhanging projections 31. The corner frame members 1'] and 23 are shown more particularly in Fig. 9.

A frame supporting member 33, having lugs 34 on each end, is cast with an upstanding flange 35 near each end. The supporting member 33 is adapted to be positioned longitudinally of the burner portion 16 between the corner frame members 17 and 23 and to be secured in place above the slot 21 by the lugs 34 on the member 33 engaging with the slots 32 and held therein with washers 36 and nuts 3'7 threaded on the ends of the lugs 34 against the rear faces of the slotted lugs 28. The upstanding flanges 35, near each 5 end of the member 33, are offset from the top edge 38 of the frame supporting member, as shown in Fig. 8, and are adapted to seat in the grooves 29 below the overhanging projections 31 of the lugs 28. The member 33 is substantial- 66 1y angle shaped in section, having an internal ledge 39 cast at the bottom of the frame supporting member, and extending between the offset flanges 35. A space is thus provided in the burner portion 16 below the member 33, into which a usual drip pan 41 is arranged to seat in the slot 21 and the corresponding recessed or slotted portion 26 of the member 23. A utility drawer 42 for cooking utensils is arranged below the drip pan 41 and extends between the corner frame member 17 and the side 24 of the oven and broiler portion 13, as shown in Fig. 1.

The burner portion 16 is provided with a substantially rectangular top frame 43 which is arranged over the burner portion 16 and is supported at its front by the comer frame members 17 and 23 and by suitable stove frame members (not shown) at its back. The top frame 43 is cast with depending sides 44 along its front and end and is an open frame having inner edges 45 which are cast to depend from the top frame and to terminate in an inwardly disposed horizontal flange 46 which extendsaround the open portion of the frame. The flange 46 is provided to support a usual burner grate 47, as shown in Fig. 1'. An arcuate horizontal lug 48 is cast at the front side of the open portion and extends inwardly from the flange 46 for the purposes to be hereinafter more fully described. A similar lug 49 is cast at'each side of the top frame open portion to adapt the frame for use on burner portions arranged at the right or left side of a gas range.

Positioned below the burner grate 4'7 are a plurality of burners 51 and 52 having burner' lead pipes 53 which are formed at their ends to provide mixing chambers 54 for mixingair of combustion with the gas for the burners. The burners 51 are supported at the back side of the-top frame 43 by means of T-brackets 55 which are bolted to projections 56 from the burners and supported on lugs 57 projecting from the top frame 43. A suitable pilot burner 58 is-provided substantially centrally of the burners 51 and 52 for the purpose of lighting the .burners and has alead pipe 59 which terminates in a pilot valve 61 communicating with a manifold 62 arranged across the front of the. burner portion 16. This manifold is suspended from the top frame 43 by means of a bifurcated bracket 63 which has a horizontal portion adapted to conform with the lug 48 to which it is bolted by a countersunk screw 64 and a nut 65. The bracket 63 has-furcations 66, which conform with the contour of the manifold 62 and which partially encircle a portion thereof. The bracket 63 serves to hold the manifold in annular grooves of a plurality of lugs 67, which are cast to the under side of the top frame 43 and depend therefrom to engage portions of the manifold.

The manifold 62 extends substantially across the front side of the burner portion16 and has a cap nut 68 which closes the oven end of the manifold. The other end of the manifold threads into a pipe L 69 which communicates with a manifold supply pipe 71 mounted along the side of the burner portion 16 by means of a bolt 72 passing through the lug 49 and a bracket identical to .the suspending bracket 63 and grooved depending lugs 73. The manifold supply pipe is threaded on its end. opposite the pipe L 69 for the purpose of connection to a source of fuel supply from which fuel may be supplied through the supply pipe and the manifold to the burners in the burner portion 16 and to the-ovens 14, the fuel flow being controlled by a plurality of valves 74 and 75 suspended from the manifold 62 with which the valves are threadably connected. The

'77 which extend outside of the burner portion 16 and are provided with suitable control handles 78 which are secured to the stems 77 by means of suitable screws 79.

The mixing chambers 54 are of usual or preferred construction and are provided with adjustable air shutters 81 adapted to have set adjustments and to be held in an adjusted position by meansof set screws 82. The air shutters are provided to control the amount of air admitted to the chambers 54 for mixing with the gas for the burners.

A heat baflling means is provided between the burners and the manifold 62 and the valves 61,

74 and 75 for the purpose of protecting thevalves.

the flange 46 at the front side of the burner portion to below the valves 74 and which has a plurality of slots 84 arranged to co-operate with and to slide around valve portions 85, asshown in Figs. 3 and 4. The slots 84 have a side formed arcuately outwardly of the slots to permit access to the set screws 82 without disturbing the plate 83 for adjusting the mixing chambers 54 to control the amount of air supplied to the burners.

The front baffle plate 83 is suspended from the flange 46 of the top frame 43 by slotting the baflle plate and sliding it between the face of the bracket 63 and the lower face of the lug 48', so that the slot cooperates with the bracket mounting screw 64, as shown in Fig. 5. The baflle plate 83 extends from the oven side 24 iongitudinally of the burner portion 16 and is slotted at its end to slide around the pipe L 69 which connects the manifold 62 and the manifold supply pipe 71, as shown in Fig. 6. The horizontal face of the baffle plate on each side of the bracket 63 is inclined upwardly along its edge behind the depending portion 45 of the top frame 43, as shown at 86 in Fig. 4. A rear baflieplate 87 is spaced apart from the baffle plate 83 and mounted therefrom by means of a plurality of brackets 88 suitably secured at one end to the plate 83, and at the other end to the plate 87. The plate 87 is reverse-lapped along its topmost edge, as shown at 89, to facilitate making and to strengthen the connection between the brackets and the plate, and has a plurality ofslots 91 adapted to register with and to slide around the mixing chambers 54. The bafiie plate 87 extends from the oven side 24 longitudinally of the burner portion 16, and is slotted at its end for a purpose to fold from the heat of the burners.

A metal channel 92 is arranged around the "17 and 23.

manifold supply pipe'll, as shown in Figs. 2 and 6, and is suspended from the top frame 43 by securing the top face of the channel between the lug 49 of the top frame and the bifurcated lug supporting the manifold supply pipe, as shown in Figs. 2 and 6. The channel 92 serves as a. baflie against the heat from the burners 51 and end of the plate 87 to a line just behind the manifold 62, where its end nearly abuts the front baffie plate 83. p n

In order to conceal the manifold and valves, a removable plate 93, shown particularly in Fig. '7, is provided .to seat on the frame supporting member 33 between the corner frame members The plate 93 is cast with slots 94 extending up from its lower edge which register with the valve stems 7'7. Suitable words are cast on the face of the plate 93 around the slots 94 to indicate the valve positions by the relative positions of the handles ,78 and the words around the slots 94.

A flange 95 is cast on the bottom edge of the plate 93 so that the flange follows along the horizontal edge on each side of .the plate around the slots94, the flange being engageable behind the valve handles when the plate is in its normal position. Near the ends of the plate 93, a vertical flange 95' (Fig. 6) projects inwardly from the inner face of the plate and is engageable with the edges of the ledges 27 provided in the corner frame members 1'7 and 23, the ends of the plate lapping the ledges 27, as shown in Fig. 6, to provide against movement of the plate inwardly or longitudinally of the burner portion.

Intermediate the ends of the plate 93 a plurality of depending flanges 96 are cast on the inner edge of the flange 95 and are arranged to engageably interlock behind the edge 38 intermediate the ends of the frame supporting member 33. The ends of the plate 93 are arranged to rest against the ledges 27 of the comer frame members 1'7 and 23. The plate 93 is of such dimension'that its top edge is concealed by the depending side 44 of the top frame but does not extend upwardly to the lower face of the top frame.

To clean or to adjust the valvesor to adjust the air shutters 81, the plate 93 is removed by prying between the plate 93 and the frame supporting member 33 until the fingers can be inserted therebetween at suitable finger hms 97 projecting inwardly of the burner portion near the ends of the flange 95. The plate 93 is then raised and the top tilted back towards the baflle plate 83, as shown by the dotted lines in Fig. 4. When the plate 93 has been raised until the flange 95 around the slots 94 clears the valve handles '78, and when the depending flanges 96 ofthe plate clear the edge 38 of the frame supporting member 33, the plate may be removed by pulling outwardly onthe bottom. In this manner, the valves are exposed and may be adjusted or cleaned, and the set screws 82 may be adjusted to contrdl the amount of air supplied to the mixing chambers 54.

The plate 93 may then be replaced by tilting and inserting its topmost edge under the depending side 44 of the top frame and by raising the plate 93 until this edge rests in the angle formed by the lugs 67 and the top frame. In this position, the slots 94 are aligned with the valve handles '78 and clear the handles, so that the bottom of the plate may be pushed back beyond the handles and the plate lowered to the position illustrated in Figs. 1 and 5.

It will be seen that the manifold 62 and the valves are positioned between the front baffle plate 83 and the removable plate 93, so that the manifold and valves are concealed from view and are protected from the heat of the burners to provide against the valves sticking due to the heat. The manifold supply pipe '71 also is concealed from view and protected from the heat of the burners, in order that heat will not be conducted from the supply pipe '11 to the manifold 62 and to the valves, causing the valves .to stick in operation.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
