UNITED STATES PATENT, OFFICE.

HENRY KIELBERG, or MARTINS FERRY, 01110, AssIGNoR 'ro WHITAKER-GLESSNER COMPANY, or WH ELING, WEST VIRGINIA, A CORPORATION or WEST VIRGINIA;

GRID EoR GAS AND OIL STOVES.

Application filed October 5, 1921.

1 '0 all whom it may concern I Be it known that I, HENRY KIELBERG, a citizen of the United States of America, and resident of Martins Ferry, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Grids for Gas and Oil Stoves, of which the following is a specification.

This invention relates to stove grids vof the general character commonly employed for seating within the usual circular holes of stove tops, and it has for its primary object to provide a grid constructed of a sheetmetal stamping pressed or drawn into a novel form which affords the requisite rigidity and strength and which is adapted to successfully resist the usual tendency to become warped from heat. I

A further object is to which, in addition to being strong'and durable, is light in weight and is comparatively inexpensive to manufacture.

In describing the invention in detail, reference is herein had to the accompanying drawings, in which- Figure 1 is a top plan view of the invention, and- Figure 22, Fig. 1.

The grid constituting the inventionis fabricated from a circular sheet-metal plate or stamping and comprises a plurality of con centric upwardly pressed beads, as 2 and 3, each substantially semi-cylindrical in cross section, connected by relatively spaced radial ribs 4:, also upwardly pressed into approximately semi-cylindrical I'orm,'said ribs being separated by openings or perforations 5. A central opening 6 is encircled by the provide 1 a grid 2 is a section of the same on line Serial No. 505,458;

- inner bead 3 which may have shoot tongues 7 projecting1 radially inward therefrom. En-

circling flange or rim 1 for resting'upon the usual seating ledge which surrounds the top hole of a stove. I

The convex top surface of the beads 2 and 3, the ribs 4 and the tongues 7 are disposed in a common horizontal plane, asshown in Fig. 2.

As is apparent, the grid described may be readily produced by simple and common pressing or drawing methods, and, conse quently, isirelatively inexpensive to manufacture. Moreover, the concavo-convex form of the various parts of the structure provides not only for strength and rigidity, for great resistance against warping.

What is claimed is- Y As a new article of manufacture, a onepiece fretwork grid for the circular holes of stove tops, said grid. being stamped from sheet metal and consistin of concentrically disposed rings, relative y spaced radial bridges joining said rings, said rings and said bridges being pressed into substantially semi-cylindrical form in cross section, the spaces between said rings and said bridges being wholly open'to thepassage of flame,

and a circular seating flange extending outa wardly from the outer of said rings.

In testimony whereof, I aflix my signae outer bead 2 is a flatterminalg 5-5 but alsol.
