Application July 21, 1931.. seam... 552,211. 7

4 claims. (01. 126-215) My inventionrelates to improvements in safety gas grates and it consists of the combinations, constructions and arrangements, hereinafter described and claimed.

An object of my invention is to provide a safety gas grate which may be quickly attached to a stove and positioned above a burner so as to support a receptacle and prevent the water from the receptacle dropping down upon the 10 flame should the receptacle boil over. The means actually contacting with the receptacle for supporting it provides a liquid-tight seal which prevents water flowing down the outside of the receptacle from gravitating along the bottom of 16 r the receptacle and then dropping upon the flame. The device employs grooves terminating beyond the circumference of the burner so that water dropping from the outer end of the grooves will not find its way down on the flame. The device .!Lwill effectually protect the flame regardless of how violent the overflow from the receptacle may be.

A further object of my invention is to provide a device of the type described which is simple in gconstruction and which is durable and eflicient for the purposes intended.

Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in 30 the appended claims.

My invention is illustrated in the accompanying drawing forming a part of this application, in which Figure 1 is a top plan view of my device;

,5? Figure 2 is a transverse section through the device; a

Figure 3 is a section along the line 3-3 of Figure 1; V I

Figure 4 is a perspective view of a portion of 9 I the device; and

Figure 5 shows a sectional view of a modified form of the device. 7

In carrying out my invention I make use of a gas grate indicated generally at 1 (see Figures 1 451 and 2) and this grate has radially extending bars 2 projecting inwardly, these bars being slightly inclined in the manner shown in Figure 2. It is obvious that the bars may be horizontally disposed if desired'without departing from the spirit 95.. and scope of my invention.

My device comprises a ring-shaped member indicated generally at 3, this member having an apron 4 and an annular flange 5 extending upwardly fromthe'ap'ron and being. integral there- 5 Eiwith. The apron is provided with a plurality of arch shaped members 6 which form grooves '7. (see Figure 2) for receiving portions of the bars 2. If desired cement may be usedfor securingthe bars 2 to the apron rafter the bars have been disposed in the arch-shaped members. If the bars 2 are inclined as shown in Figure 2 the cement need not be used because any water draining beneath the arches 7 will drop upon the bars 2 and be conveyed away from the burner 8 instead of toward the burner, due to the inclination of the bars. The purpose of the cement is to prevent this draining of the water along the bars 2 should they be disposed in a horizontal position j which is' the general practice.

Between the arches 7 I dispose sighting grooves 9 formed in the under side of the apron 4. Portions of the apron 4 are bent in the manner shown in Figure 3 for forming the sighting grooves 9. When the device is placed on the grate 1 the grooves 9 extend at an angle which permits the operator to look at the flame without the necessity of stooping over so far as when it is necessary to lower the eyes to the level of the bottom of the receptacle.

It is obvious that the sighting grooves 9 may be dispensed with if desired as shown in Figure 5 without departing from the spirit and scope of my invention. r

A flexible ring 11, preferably of asbestos, is placed around the flange 5 and is held in place by a split clamping ring 12. The ends of the ring 12 have

ears

13 and 14 with openings'and a bolt 15 is inserted through the openings and may be tightened for clamping the ring 12 about the flexible ring 11.

The flexible ring extends above the tops of the flange 5 and the ring 12 and is preferably made of asbestos so as to be fire resisting.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

The receptacle 10 is placed upon the device so as to be supported by the ring 11 as shown in Figure 2. The ring 11 will conform to the irregu- While I have shown only the preferred forms Y of my invention, it should be understood that various changes or modifications may be made within the scope of the appended claims without g grate having an apron with arches for receiving departing from the spirit of the invention.

I claim: I

1. A safety gas grate comprising an outwardly extending apron, a flexible and non-inflammable member disposed about the ring, and a split ring clamping the member to the first ring, said member projecting above the rings.

"2. A safety gas grate comprising a ring having an outwardly extending apron,a' flexible and non-inflammable member disposed about the a ring having,

ring, and a split ring clamping the member to the first ring, said member projecting above the rings, said apron having water conveying grooves therein.

3. The combination with a gas stove having bars, of a ring having an integral apron with water grooves, said apron also having arches for receiving the bars, and a flexible, non-inflammable member secured to the ring and projecting above it; a i J 1. The combination with receptacle supporting bars disposed above a burner, said bars being inclined downwardly at a slight angle from a position above the center of the burner, of a safety the barsand, having water conveying grooves in its upper surface, and a flexible, non-inflammable member disposed adjacent to the inner edge of "the apron and designed to support and form a water-tight seal withra receptacle for deflecting overflowing water from the receptacle the apron.
