Beit known that I, GEoRGEEg-PALMER, of Elmira, in the county of Chemung, in the State of New York, have inventedy new and useful Im rovements in Stove-Rings, of which the fo lowing, taken in connection with the accompanying drawings, is a full,

clear, and exact descriptlon.

This invention relates to` certain improve# ments in stove rings for receiving and supporting cooking utensils some distance above the surface of the'stove to prevent burning of the cooki material.

My main o ject is to provide a stove ring I for the purpose described and which is comparati-vely light and may be manufactured at a minimum cost and at the same time afford Ventilating means for the' escape of the heated air fromv within the ring when the cooking utensil is mounted thereon. In other words, this object more specifically stated is to make the body of the r1 from a single piece of light sheet metal inw 'ch the vent openings are stamped or pressed therein and to reinforce the longitudinal edges of .the by wires over which portions of the sheet metal band are bent and to provide the meeting ends'of the sheet metal body with integral parts adapted to be bent or clenched 1nto interlocking engagement with each other. y

In the drawings-Figure 1 is a face view partly in section and partly broken away of the extending band and reinforcing rods for forming the ring Fig. 2 is a pers ective view of the completed stove ring. Fi) 3 is an elevation of the same showing a ettle mounted thereon. F' 4 is an enlarged face view of the meeting ends of the ring showing the interlocking members in operative position.- Fig. 5 is a sectional vie taken on line 5-5, Fig. 4. e f

As shown in the drawings this stove ring consists essentially of a strip1.1 of comparatively light lsheet metal site longitudlnal edges or rods provided with over turned lengthwise ilanges -2- inclosing suitablereinforcing wires -3- which latter may, however, be omitted if desired and the over turned ed es v.-2#- relied upon to sufficiently stiffen t e sheet metal strip -1-.

The intermediate portion of this strip -1-,- is formed at intervals with a series of diamond-shaped perforations 4 formin vent openings to permit the escape of heate aving its oppoair from within the ring when it is resting on the stove .with a kettle or other cooking utensil as .5 mounted thereon as best shown inFig. 3.

One endof the strip -1- is formed with an integral tapered ton e -6- while theolpposite end is forme with a transverse s ot --7-- of substantially the same dimensions as the transverse dimensions of the tongue -6- which it is adapted to receive when the ends are brought together as shown in Figs, 2, 3, 4 and 5;

-The end of the sheet metal stripl -1- which is formed with a slot -7- is proing a central lengthwise slit or slot -9- extending inwardly from its extremity for the purpose of forming opposite locking members -10- adapted to be folded on diagonal lines .-11 and against the sides il); one of the openings -4 as best seen in When thestrip is bent in circular form as shown in Fig. 2, the extension 8 is lap ed u on the outer face of the opposite en of t e strip between the flanges 2 -whereupon the tongue -6- is bent laterally and inserted through the transverse slot 7 and clenched upon the outer face of the extension -8- and at the same time the interlocking members -10- at opposite sides of the slit 9 are bent through the adjacent opening -4 and clenched upon I'the inside of the strip 1 thereby affording a double lock for the meeting ends of the ring'. It is now apparent that the opposite ends of the strip are reduced to somewhat less width than the main body of the strip forming shoulders -12- at the'base of the tongue -6- and additional shouldersl 3- at the b ase of the reduced extension -8-, said shoulders formingabutments which are brought together and determine the circumference of the ring as clearly' seen in Figs. 2 and 3.

The slot 7- is disposed in substantially the sametransverse line as the shoulders -13- While the sides of the opening -4- nearest the base of the tongue -6- are disposed a distance from the base of said tongue substantially equal to the distance between the slot -7- and diagonal linesu ing members -10- will be brought into registration respectivelyA with the transverse slot -7- and adjacent sides'of the opening -4- nearest the tongue (5- whereupon said tongue 6- may be readily vinserted through the slot -7 and clenched u on the outer face of the extension -8- an at the same time the locking members -10- are folded upon the lines 1lthrough the adjacent opening l1- and clenched upon the inner side of the stri thereby firmly locking the meeting ends o the band together and forming a practically rigid annulus or ring capable of supporting ordinar cooking utensils.

hat I claim is:

1. A stove ring comprising a sheet' metal strip havin its opposite longitudinal edges over turne towar each other and inclosing lengthwise reinforcing wires, the intermediate portion of the strip being formed with vent openings, one end. of said strip being reduced in Width andprovided with a central lengthwise slit opemng from its eX- tremity and provided with o posed bendable locking members adapte to enter one of the vent openings in the opposite end of 1 the strip and to be clenched upon the sides of said opening.

2. A stove ring comprising a sheet metal strip bent into circular form and havin its opposite longitudinal edges over turne toward each other forming lengthwise reinforcing flanges, the main body lbeing formed with vent openin s, reinforcing rods embraced Within sai flanges, one end of the strip being providedwith a tongue and the opposite end being formed with a groove, the tongue being inserted through the groove and clenched upon the adjacent portions of the strip, the end of the strip oifset to that which is .provided with a tongue having a reduced extension formed with a lengthwise slit opening from its extremity forming opposed bendable locking members adapted to be inserted through and clenched upon the sides of one of the vent openings.

In witness whereof I have hereunto set my hand this 13th day of July 1907.
