GRATE FOR OIL AND GAS STOVES I Filed Feb. 4, 1927 INVIENTOR.

Patented May 20, 1930 UNITED STATES PATENTv OFFICE LEWIS T. WILCOX, OF PEEKSKILL, NEW YORK Application filed February 4, 1927.

(ii-RATE FOR OIL AND GAS STOVES This invention relates to grates for oil and gas stoves. Heretofore, as I am aware, grates for oil and gas stoves have been constructed ported by the top of the stove.

There are various other manners in which these grates have been made. The type of grate to which my present invention relates is that in which there is a peripheral portion adapted to rest upon the upper member of a stove and with which there is associated a plurality of arms extending inwardly and terminating short of the central portion of the grate in order to provide a clear space for the flame from the burner to impinge directly upon the under surface of a cooking or other utensil supported by the grate in order to obviate the loss of any of the heat from the flame as applied to the utensil. The grate made in accordance with my present invention is preferably constructed from a plurality of members each formed in a similar manner to include a peripheral portion with angles thereto so that when sembled by connecting the arms turned at the parts are asarm members of adjacent sections the peripheral portions thereof form the rim of the grate, as will be hereinafter more particularly described.

In the drawing Figure 1 is a plan of a grate made in accordance with my present invention.

the top of a stove, and

that in carrying out the invention the grate made in accordance therewith is one that comprises a plurality of similarly formed sections. These sections are preferably made of band metal and as illustrated, each section is formed to include a peripheral portion 10 and arms 11 and 12 bent at angles thereto. Furthermore, as illustrated, theperipheral portions illustrated are arcuate, that is they are made on arcs of a circle, and the arms 11 and 12 are bent to such positions that when the parts are assembled to form the grate these arms lie in radial positions. It Will be under-- stood, however, that the'peripheral portions may be made straight or otherwise and the arms formed at the extremities thereof bent at any desired angle so as to lie in predeter-' mined positions when the article is completed. Also as illustrated in the drawing, the extremities of the arms are preferably tapered, for example the end of the arm 11 is oppositely tapered or beveled as designated atj13- and 14 and the end of the arm 12 is similarly formed as indicated at 15 and 16.

In assembling the sections'which comprise the grate the parts thereof after being placed and held in position may be united by being welded or bolted or otherwise, having the adjacent sections connected to each other. As illustrated, the section including the arcuate portion 10 has an adjacent section whose arcuate portion is indicated at 17. The arm 18 of the arcuate portion 17 is connected to the arm,11 of the arcuate portion 10 by being spot Welded thereto as indicated at 19. The next adjacent section to the section having the arcuate portion 10, but on the other side thereof, is one wherein the arcuate por tion is indicated at 20. The arm 21 of this section is connected to the arm 12 of the section having the arcuate portion 10 by being welded thereto or otherwise, while the arm 22 of the section'having the arcuate portion 20 is connected in a similar manner to the arm of the section next adjacent thereto. The grate is built up in this manner so that when completed the arcuate portions of the sections form the rim of the grate and the arms extend in radial positions terminating short of the center of the grate so as to leave an appreciable space in a centrally disposed position in order not to interfere in any manner with the impingement of the flame against the under surface of a cooking or other utensil supported by the grate, thereby interfering in no manner with the application of the heat from the flame to the utensil.

The ends of the radial arms are beveled as indicated to provide a more or less ornamental appearance to the grate and to make it possible to reverse the position of the grate in use without changing the appearance of the same in the stove. It will be understood, of course, that the arms may be of any suitable length and that while the arms as illustrated are of difi erent lengths, the short arm of one section being connected to the longer arm of the nextadj accnt section, the arms of thesections may beformedof any length whatsoever in order to provide the necessary strength in these arms for supporting cooking and other utensils depending upon the character of the stove in which the grates are employed. Also as illustrated, the grateis adapted to set within an inturned flange 23 in the top 24:

of a stove, but this ismerelyillustrative of the use of the grate, as it may be supported in any desired manner on the top of the stove. It will 'furthermore be understood that while the grate as illustrated is circular and formed of six sections, the sections may be so constructed as to form a grate of any desired number of sections and to have a rim of any necessary configuration.

I claim as my invention:

1. A grate adapted to overlie an oilor gas burner comprising a plurality of sections of band material each section having an arcuate peripheral portion and angular arms of different lengths, the sections being disposed with their arms extending inwardly and with the short arms of each section engaging the longer arms of the succeeding section, and being secured thereto to form a substantially circular grate.

2. A grate adapted to overlie an oil or gas burner comprising a plurality of sections of band material each section constituting a sector of a circle having radial arms of- LEXVIS T; WVILCOX.
