The cored cast .iron frame---is objectionable by reason of itsweight, cost,[fragility and the danger ofjleakage due toblow metal. The cast iron frame is also objectionable by reason of itstendency to" warp and become twisted or distorted due tothe heat from the burners.

produce astrongydurableand rigid lightweight grid supporting top frame of simple and economical manufacture and compact doe-i sign which will not leakor warp and which will present aneat and attractive appearance. a

The invention consists in a grid supporting frame whose rear rail and one side rail are formed of angle iron and whose front and other side rail are formed of metal tubing. The invention also consists in the construction, combinations and arrangements 'of'parts hereinafter described and claimed.

In the accompanying "drawings, whichforms part of this specificationand wherein I like symbols refer to like parts wherever they occur, a

At the corner of the frame, where the angle iron rear rail 4 joins the tubular side rail 2, the end of the angle iron rear rail abuts against the inner side wall of the tubu acrossthe open end of said tubular front rail,

intermediate its ends to form twobranches 1 that are disposedatright anglesto each other, r

preferably by welding. As shown in the drawing, the tubular side rail 2 is extended beyond the rear rail of the frame and terminates in a threaded end portion 8 adapted for connection with the main gas supply pipe 9.

Among the advantages of the hereinbefore described grid supporting frame are its light weight, durability, strength and rigidity, and its simplicity and cheapness of construction. It is also noted that an important advantage of my invention is that it resists any tendency for the rails to warp and become twisted or distorted by the heat from the gas burners and that the density of the metal of the steel tubing and the arrangement for closing the end of the tube which forms the front rail of the frame eliminate the danger of the escape of gas therefrom.

What I claim is:

A grid supporting top frame for gas stoves comprising front, rear and side rai1s,the rear rail and one side rail comprising a rolled structural steel member of substantially angle-shaped section, and the front rail and other side rail comprising sections of steel tubing of substantially rectangular section, the adjacent ends of said tube sections being welded together, the angle member abutting against the inner face of the tubing at one corner of said frame and being welded thereto, and the tubing extending beyond the angle-shaped rail at said corner of said frame and terminating in a threaded portion adapted to receive a pipe fitting, said angle member overlapping the adjacent end of the tube forming the front rail of said frame to close the same and being welded thereto.

Signed at St. Louis, Missouri, this 29th day of June, 1928.
