GAS BURNER FOR COOK STOVES

Emil Kunz, Chicago, Ill.

Application March 30, 1932. Serial No. 602,115

This invention relates to improvements in gas thereof, from an inspection of which, when con burners, and more particularly to the type of sidered in connection with the following de Scription, my invention, its mode of operation, gas burner employed in cooking stoves, or the construction and assembly, and many of its ad like.

Another object of this invention is to provide on, part of the latter being broken away for the for a gas burner of a cook stove or the like a plurpose of clearneSS;

My improved attachment, which is designated 90 35 the extinguishing of the fame issuing from the generally by the reference character 10, com escape-Orifices, said attachment being adapted prises a stem portion 11 and a hood portion 12, for easy connection with said burner, may be said stem portion being adapted for resting on manufactured at a low cost, and is highly effi cient for carrying out the purposes for which it the portion 5 of the burner. There are provided at diametrically opposite points on said burner 95 40 is designed.

With the foregoing and other objects in view a pair of upstanding pins or lugs 13, which are which will appear as the description proceeds, the adapted to cooperate with a pair of recesses 14 invention consists in certain novel and improved provided holding in the under side of the stem 11 for features of construction, arrangement and com Securely burner. The the attachment in place on the attachment may be made of any 100 45 bination of parts hereinafter more fully de suitable material, such as scribed, illustrated in the accompanying draw material is adapted to retain the iron or the like, which heat for a con ing and particularly pointed out in the appended siderable period of time after the supply of gas claims, it being understood that various changes in the form, size, shape and minor details of the has been shut off.

The hood portion 12 is curved on its upper sur- 105 50 construction may be made without departing face, as shown in the drawing and as the side from the Spirit or Sacrificing any of the advan portions 15 thereof project beyond the escape tages of the invention.

For the purpose of facilitating an understand orifices 3 and 4, it will prevent the spilling of . ing of my invention, I have illustrated in the liquid onto Said escape-orifices. As shown more clearly in Figure 3 of the drawing, the project- ll.0 accompanying drawing a preferred embodiment
