GRATE STRUCTURE FOR GAS RANGES Filed Jan. 26. 1952 United States Patent GRATE STRUCTURE FOR GAS RANGES Henry Honer, Los Angeles, Calif., assignor to Western Stove Company, Inc., Culver City, Calif, a corporation of California Application January 26, 1952, Serial No. 268,417

4 Claims. (Cl. 126-215) My invention relates to grate structures for. gas ranges, and included in the objects of my invention are:

First, to provide a grate structure for gas ranges which comprises a pair of complementary coplanar grate members, each capable of being used individually as well as in conjunction with each other.

Second, to provide a grate structure for gas ranges which, when the grate members are used individually, provides either a small grate for small cooking vessels, and a large grate for large cooking vessels, each arranged to expose direct to the burner flame a portion of the cooking vessel, and further provides, when both grate members are used together, a protective wall between the flame of the burner and the cooking vessel to facilitate low temperature cooking.

With the above and other objects in view as may appear hereinafter, reference is directed to the accompanying drawings in which:

Figure l is a plan view of the inner grate member.

Figure 2 is a plan view of the outer grate member.

Figure 3 is a plan view of the two grate members as arranged for conjunctive use.

Figure 4 is a transverse sectional view through 4-4 of Figure 3 showing fragmentarily a burner and mounting ring with which the grate structure is used.

An inner grate member 1 is provided which is in the form of a plate having radiating projections 2. In the structure shown, six such projections are provided. Secured to the underside of three of these projections are radiating legs 3. The inner ends of the legs 3 may underlap the projections and spot welded thereto. The legs are preferably channel shaped in cross section and terminate in rounded, downwardly-turned feet 4.

An outer grate member is provided. This member is in the form of a flat disk provided with a central opening 6, the margin of which comprises a series of recesses 7 separated by radially inwardly directed projections 8. The pattern formed by the central opening 6 coincides with the margins of the inner grate member 1 so that the outer grate member may be fitted over the inner grate member as shown in Figure 3. When so arranged, the grate members are coplanar and present a substantially solid surface broken only by the relatively narrow slit formed between the confronting margins of the two grate members. The outer grate member is provided with feet 9, corresponding to the feet 4. In the structure shown, three of such feet 9 are provided and are adapted to be located midway between the feet 4. The upper surfaces of the legs 3 may serve to aid in the support of the outer grate member indicated in Figure 4.

In practice, the grate members either individually or in conjunction with each other are adapted to rest on a mounting ring R which fits around a conventional range burner B. The margins of the ring R are provided with a rib to aid in centering the grate members.

Having fully described my invention, it is to be understood that I do not wish to be limited to the details herein set forth, but my invention is of the full scope of the appended claims.

I claim:

1. A grate structure for cooking ranges, comprising:

a mounting ring adapted to be disposed in concentric relation with a cooking range burner, said mounting ring having an annular supporting surface bordered by a retaining rim; an inner grate plate having a plurality of radially outwardly directed fingers; radiating legs protruding beyond alternate fingers and downtourned at their extremities to form supporting feet adapted to rest on the supporting surface of said ring and be retained within said rim; an outer grate plate circular in outline and having a plurality of radially inwardly directed fingers intermeshing with the fingers of the inner plate whereby said plates may be disposed coplanar-1y; and downtourned feet extending from the periphery of said outer grate plate and, when said plates are intermeshed, disposed between the supporting feet of the inner grate plate and also adapted to rest on the supporting surface and to be retained within the rim of said mounting ring.

2. A grate structure for cooking ranges, comprising: a first outer grate plate having a central opening, the margins of which form alternate radially inwardly directed projections and radially outwardly directed recesses; a second inner grate plate conforming to and filling said opening, said grate plates being coplanar; and a set of radiating supporting feet for independent support of each of said grate plates, each of said grate plates being operable independently of the other as well as simultaneously operable.

3. A grate structure for cooking ranges, comprising: a first outer grate plate having a central opening, the margins of which form alternate radially inwardly directed projections and radially outwardly directed recesses; a second inner grate plate conforming to and filling said opening, said grate plates being coplanar; a first set of radiating feet for said inner second grate plate extending under and beyond said outer grate plate; and a second set of radiating feet for said outer grate plate, said sets of radiating feet providing independent support of said grate plates, each of said grate plates being operable independently of the other as well as simultaneously operable.

4. A grate structure for cooking ranges wherein each burner is provided with a concentric mounting ring having a marginal supporting surface and surrounding rim, comprising: an inner grate plate having a plurality of radially outwardly directed fingers; radiating legs protruding beyond alternate fingers and downtourned at their extremities to form supporting feet adapted to rest on the supporting surface of said ring and be retained within said rim; an outer grate plate circular in outline and having a plurality of radially inwardly directed fingers intermeshing with the fingers of the inner plate whereby said plates may be disposed coplanarly; and downturned feet extending from the periphery of said outer grate plate and, when said plates are intermeshed, disposed between the supporting feet of the inner grate plate, and also adapted to rest on the supporting surface and to be retained within the rim of said mounting ring.
