DOMENICK SAPONARA BY A TORNEY United States Patent 2,991,783 MEANS FOR LOCATING THE SURFACE BURNERS AND THE PILOT BURNER OF A COOKING RANGE Domenick Saponara, Allentown, Pa., assignor to Caloric Appliance Corporation, Topton, Pa., a corporation of Pennsylvania Filed Jan. 21, 1958, Ser. No. 710,276

2 Claims. (Cl. 126-214) A conventional cooking stove, be it gas burning, or electric, includes a main cooking top having a number of openings and a corresponding number of surface burners located in said openings. If the stove is gas burning, it will also include a pilot burner and flash tubes for automatically igniting the surface burners when the gas is turned on.

In either case, it is necessary that the surface burners be centered with reference to their respective openings, and in a gas burning stove, it is also necessary that the flash tubes be properly located with reference to the pilot burner. It is, of course, possible to accomplish these results by precise machining, the expense of which is prohibitive, and by permanent assembly, which precludes dismantling for cleaning and repair.

It is therefore one object of this invention to provide improved mounting means for accurately locating the surface burners with reference to their respective openings and, in the case of a gas burning stove, for also accurately locating the flash tubes of the surface burner with reference to the pilot burner.

The surface burners of a gas burning stove are wholly detachable from the structure of the stove itself and it is, therefore, desirable that they be shipped in the form of a separate package, that is, without being mounted in their respective openings. Also, when in use, the burners have to be removed periodically for cleaning, or for repair.

It is therefore a further object of this invention to provide improved, simple, durable and inexpensive locating means whereby the surface burners of a stove can be mounted, demounted, and remounted, instantly, without any skill, and with perfect assurance that the surface burners will be properly centered with reference to their respective openings, and that their flash tubes will be properly located with reference to the pilot burner.

The full nature of the invention will be understood from the following specification and accompanying drawings, in which the figure is a fragmentary, exploded, perspective view showing the improved mounting bracket of my invention and its relationship to the main top and to the pilot burner of a gas burning stove.

Since the stove itself is conventional and forms no part of the present invention, it is not shown nor described. Instead, only a portion of the main cooking top of the stove, and only a portion of the pilot burner, which are the only parts to which the invention is related, are shown.

The main, or cooking, top of a conventional stove can have one or more front, and one or more rear, openings which register with the front openings, and burners, front and rear, located in said openings. In the fragmentary illustration forming part of this disclosure, only a portion of the main cooking top of the stove is shown with a front burner opening 12 for accommodating front burner 17 and with an opening 12 for accommodating a rear burner 19.

The burner locating means of my invention consists of a bracket B which includes a bottom wall 30 and

ears

31, 32, 33 and 35, which are carried by wall 30, and are provided with elongated slots 34 for adjustable engagement with bolts or the like, not shown, which also adjustably engage

elongated openings

36 and 36 in pendent flanges 38 and 38' which are struck down from main top 10, adjustably to secure the bracket to the main top. In practice, ears 33 and 35 will be secured to flanges 38 which are associated with opening 12 and

ears

31 and 32 will be secured to flanges 38' associated with opening 12'.

Bottom wall 30 of bracket B is also provided with an opening 40 through which pilot burner 41 projects and with an upper wall 43 which protects the pilot burner flame from downward drafts and protects the pilot burner from drippings from the pots or pans used on the stove.

Bottom wall 30 of the bracket is further provided with

lugs

54 and 58 which are accurately located with reference to

ears

31, 32, 33 and 35, and with reference to opening 40, and which are engageable with

openings

52 and 56 in base portions 15 and 15' of burners 17 and 19 respectively.

With the construction described, the manufacturer, who has the required skill and tools, accurately secures bracket B to said flanges 38 in such a manner that when rearwardly extending body portion 15 of burner 17 is inserted between top and

bottom walls

30 and 43 and lugs 54 is engaged with opening 52, burner 17 will be centered relative to opening 12 and so that, when forwardly extending body portion 15 is inserted between

walls

30 and 43 and lug 58 is engaged with opening 56, burner 19 will be accurately centered with respect to opening 12'. With pilot burner 41 projecting through opening 40, the ends of flash tubes 27 of said burners will 'be accurately located relative to pilot burner 41. By this arrangement, once bracket B is properly positioned at the factory, the burners themselves can be assembled, dismantled and reassembled, without any skill and without any tools, and with complete assurance that burners will be properly centered relative to their openings, and with complete assurance that the ends of their flash tubes will be properly located relative to pilot burner 41 so that the surface burners will be automatically ignited whenever the gas is turned on.

Because the bracket is adjustably secured to the main top, it is made of a stamping and needs no precise ma chining. It is merely necessary to center the burners relative to their openings, and to engage

lugs

54 and 58 with holes 52 and 50, and then to secure the ears of the bracket to flanges 38. If now, pilot burner 41 is inserted through opening 40, the proper relation of the pilot burner to the flash tubes of the burners will be assured.

Iclaim:

1. In combination, a main cooking top having front and rear openings therein, a front burner adapted to fit in said front opening, a rear burner adapted to fit in said rear opening, a first, rearwardly extending base portion carried by said front burner, a second, forwardly extending base portion carried by said rear burner, there being a first hole formed in said first base portion and a second hole formed in said second base portion, a first pair of flanges depending from the edge of said front opening, a second pair of flanges depending from the edge of said rear opening, a bracket for each of said front and rear openings, each bracket including a bottom wall, a first pair of ears projecting from one end of said bottom wall, a second pair of ears projecting from the opposite end thereof, spaced first and second lugs carried by said bracket and engageable with said first and second holes, respectively, and means for adjustably securing said first pair of ears to said first pair of flanges and for securing said second pair of ears to said second pair of flanges, whereby when said burners are centered in their respective openings with said lugs engaged with said holes respectively, and said brackets are secured to the underside of said main top, subsequent removal of the surface burners and the re-engagement of said holes with saidlugs, insures the re-centering of said surface burners with reference to their respective openings.

2. The combination recited in claim 1, including a pilot burner, and flash tubes between said front and rear burners and said pilot burner, there being a third hole in the bottom wall of said bracket for receiving and locating said pilot burner relative to the adjacent ends of said flash tubes.
