7 Claims.

This invention relates to stoves and particularly to an improved construction for domestic gas ranges and has reference to the location and arrangement of parts of a stove to improve the appearance thereof to expedite the cleaning of the stove after being used and to reduce the cost of manufacture and of assembling and servicing stoves of this type. i

The embodiment of the invention selected for purposes of illustration is disclosed in connection with a table top style of domestic range which is provided with an oven compartment, a broiler compartment, one or more storage drawer compartments and a burner compartment, so arranged that the top surface of the stove cabinet lies in a horizontal plane providing the equivalent of a table top surface above the oven compartment and at substantially the same elevation as the supporting surface above the burner compartment which heretofore has been provided by an open grate with a movable panel for overlying the grate when the same is not in use.

This invention contemplates the provision of a substantially continuous top surface which may be provided by a unitary panel and in which top surface there is provided a plurality of burner openings with individual grates and closures for said burner openings, together with a novel arrangement of burners, feed pipes, drip pan and burner valve controls, wherein said burners, feed pipes and control valves are enclosed by finished panel members which serve to keep the burners, feed pipes and associated structure in a clean and sanitary condition and which in themselves may readily be cleaned.

A principal object of the invention, therefore,

is to provide an improved type of stove construction in which the feed pipes and burners and associated parts are concealed.

Another object of the invention is to provide a novel arrangement of the parts of the stove to reduce the cost of manufacturing and assembling of stoves.

Another object of the invention is to provide an improved type of burner box construction.

Another object of the invention is to provide.

a stove which is extremely attractive in appearance and which may readily be kept in a clean and sanitary condition.

Another object of the invention is to provide an improved type of burner construction whereby a greater percentage of the heat of the burner may be effectively utilized in the process of cock- Other objects and advantages of the invention will be apparent by referring to the following specification in conjunction with the accompanying drawings, of which there are three sheets and in which:

Fig. l is a perspective view of a domestic gas range having incorporated therein a preferred embodiment of the invention;

Fig. 2 is a top plan view of the burner compartment with the concealed parts illustrated in dotted lines;

Fig. 3 is a top plan view of one of the burners with parts being broken away;

Fig. 4 is a vertical cross sectional view of the burner box taken generally on the line 44 of Fig. 3 and illustrating the arrangement of parts of the burner box;

Fig. 5 is a. plan view of the control mechanism with one of the burners being illustrated in top plan view; and

Fig. 6 is a front elevational view of the external portion of the control mechanism.

Referring now to Fig. 1 of the drawings, at I!) there is illustrated in perspective the cabinet of a stove having an oven compartment l2, a broiler compartment [4, a plurality of storage drawer compartments l6, a table top surface 20, a backguard 22 therefore, a plurality of legs 24, suitably secured to the lower corners of the cabinet I0, and a burner compartment or box, indicated generally at I 8.

As illustrated, the top surface 20 of the stove cabinet may comprise a unitary panel 26, adapted to overlie the entire upper surface of the stove cabinet including the oven compartment l2 and the burner box l8: That portion of the panel 26 overlying the oven compartment I 2 is substantially flat and adapted to provide a table top or working surface, whilethat portion of the panel 26 overlying the burner box I8 is provided with a plurality of burner openings 28. The panel 26 may be finished, such as by being porcelained, similarly to the sides and front panes of the stove cabinet and the front panels of the drawer and oven compartments.

Thcse portions of the panel 26 surrounding the openings 28 may be dished and provided with a plurality of annular flanges 30 and 32 for the purpose of supporting some of the parts of the burner asembly, as will appear hereinafter.

An annularly shaped burner body 34, provided with inwardly extending radially disposed openings for supporting a flame, is provided with a plurality of lugs 33 which are adapted to rest upon the annular flange 32 for supporting the body of the burner, to the inlet 36 of which there is coupled a vertically extending manifold or mixer tube 38 which is provided with the usual air inlet openings. It may be observed that the burner 34 is provided with a central opening in which a flame is supported by the flame-supporting portions or openings in the burner body. The flame, supported by the burner 34, is directed toward the center of the opening and flows upwardly where it is adapted to engage the central portion of a cooking utensil and to flow more or less evenly in a radial direction over the bottom of said cooking utensil and upwardly along the sides thereof, as a result of which the heated ases produced by the flame will, for a maximum period of time, be maintained in contact with the cooking utensil for extracting the maximum amount of heat energy therefrom.

A feed pipe 40, suitably mounted in the stove cabinet and adapted at one end to be connected to a source of gas under pressure, extends forwardly from the back wall of the stove cabinet through the central part of the burner box and just above the upper one of the storage drawer compartments IS.

The feed pipe 46 on that portion below the burner compartment I8 is provided with a plurality of spaced upwardly extending gas cocks 42 which are provided for controlling the supply of gas to the burner 34 through the mixer tube 38. The mixer tube 38 telescopically receives the nipple 44 of the gas cock 42. When it is desired to removethe burner 34 from the stove, the same is lifted through the burner opening in the panel 26 by first lifting the-mixer tube 38 off the nipple 44 of the gas cook 42 and then swinging the mixer tube 38 to a position underneath the burner opening 28, after which the burner may be vertically removed from the stove.

To facilitate the removal of the burner 34 from the stove in this manner, the drip pan is constructed in two portions 48 and 50, so that there is a central opening between the portions of the drip pan above the feed pipe 40 to accommodate the vertically disposed mixer tube 38. The drip pans may be supported in any suitable manner such as by a continuous bracket 52 on the sides away from the center of the burner box and by a plurality of spaced brackets such as 54 along the center of the burner box, the spaced brackets 54 being necessary to permit the mixer tube to be swung below the burner opening 28. The drip pan may be of the usual construction or may be provided with bowl-shaped portions 56 stamped in the pan and which portions 56 are adapted to underlie the burner opening 28 and will be visible through the burner opening 28 when the burners are in use. Preferably, the drip pan is porcelained in a manner similar to that in which the top panel 26 is porcelained or otherwise finished. It also will be noted that the bowl portions 56 underlying the burner opening 28 will operate to catch whatever material may fall through the burner opening 28.

The front panel 60 may be formed with a portion 62 corresponding to the design of the panel portions of the drawers and oven doors and which portion is provided with an opening in which is disposed a plate 64 upon which is mounted a handle 66 for each of the gas cocks 42. handles 66 are suitably journaled in the plate 64 and are connected by rods 68 to the respective gas cocks so that the supplying of gas to each of the bu ners may be selectively controlled by manipulation of the handles 66 on the front portion of the stove. The rods 68 at each end The are connected by a universal joint mechanism 16 to the handles 66 and to the gas cocks 42. There is also provided upon the plate 64 a handle 66 connected to the gas cock at the forward end ofthe feed pipe 40 which is adapted for controlling the supply of gas to the oven burner (not shown) through the pipe 12.

It will be noted that the drip pan portions 48 and 50 are separable and that the front panels thereof are designed so as to form with the portion 62 a complete design similar to any one of the panels of the oven or drawer compartment.

Within the bowl-shaped portions 14 of the top panel 26, which portions are disposed below the surface of said panel, there is disposed a complementary shaped bowl or member 16 provided with a central opening corresponding with that of the burner 34 and which bowl member 16 is adapted to substantially cover the body of the burner 34 but to leave exposed the flame supported by the burner; that is, the flame supported by the burner 34 is supported within the opening 28, while the burner body is completely covered or shielded by the bowl 16 except for a very small annular portion which extends inwardly from the inner edge of bowl 16, thus preventing the flame from directly contacting said bowl. Bowl 16 operates to deflect any solid material dropped into the opening toward the center thereof where the same may fall into the bowl portion 56 of the drip tray without coming into contact with the body of the burner. The bowl member 16 simply rests in the bowl portion 14 and is readily removable therefrom. For each burner there is provided an individual grate 18 which is supported by the panel 26 on the flange 36 thereof, and which grate, together with the bowl member I6, is readily removable when it is desired to remove the burner from the stove. Individual covers are provided for each of the burner openings and are adapted to be supported on the annular flange 30 of the top panel 26. It will be apparent that the burners of the stove may be used in the same manner in which burners of present day stoves are used, but, as is frequently the case, if it is desired to use only one burner at a time with the present construction, it is unnecessary to uncover all of the burners, but simply the selected one or ones.

It is to be understood that the invention is not to be considered as limited to the embodiment and application thereof which has been selected here for the purpose of illustration, but is intended, rather, to embrace and include all other embodiments and applications of the new and useful principles thereof which are to be considered reasonably within the scope of the appended claims.
