MAURICE MATHY, OF LIEGE, BELGIUM.
COOKER.-
Application filed July 17,
To all whom it may concern:
Be it known that I, MAURICE MATHY, manufacturer, a subject of the King of Belgium, and resident of Liege, in the Kingdom of Belgium, have invented certain new and useful Improvements in Cookers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked therein, which form a part of this specification.
This invention relates to cookers which are heated by gas according to the socalled flameless combustion or incanoescent method.
This result is obtained by arranging in place of the ordinary fire box of a cooker, a burner for flameless combustion or incandescent burner.
Above this burner a block of refractory material is arranged in order to avoid too intense a heating of the vessels placed on the opening in the ring or top plate.
Air is introduced to the burner without the use of a fan or blower by means of a chimney arranged beneath the burner and exposed to the heat of the cooker in such a way as to cause therein a suflicient draft.
The drawings accompanying the present specification illustrate as an example a form of construction of the invention.
In these drawings Figure 1 is a vertical section lengthwise on the line A B of F ig. 2.
Fig. 2 is a transverse section on the line C D of Fig. l.
3 is a detail horizontal section showing the damper for controlling the air supply.
Between the chests or boxes 1 serving as the ovens a burner is arranged which is fed with gas by a pipe 2 provided with a regulating valve 3 controlled from the outside by a handle 4;.
This gas is brought into an annular space 5 comprised between a cup-shaped metal part 6 and a fire clay basin 7, the latter terminating at its bottom in a depending tubular neck 8 which rests upon the bottom of cup 6 and which communicates by means of slots 9 with the space 5. The base of this neck 8 communicates by way of slots 10 Specification of Letters Patent.
Patented Aug. 23, 1921. 1919. Serial No. 311,608.
formed in the bottom of said cup 6 with the upper end of the elongated stem of a funnel 11, the frusto-conical lower portion or bell of which is arranged toward the bottom of the cooker.
This funnel ll acts as a draft chimney because of the radiating heat which it receives from the cooker. The cold air drawn into its lower part or bell rises in said funnel l1 and passes through the slots 10 into the neck 8 of the cup or basin 7 where it meets the gas introduced by the pipe 2.
- The mixing of the two gases and their combustion takes refractory material which is contained in the neck 8 of the basin 7.
The hot gases rise in the space 12 above said basin 7, pass through the fines 13 and the hole 14 formed in a refractory plate or block 15 arranged above the burner andpenetrate into the space 16 limited at its upper part by a top plate or rlng 17.
These gases then flow around the ovens 1 and pass to the chimney 19. Access of air to the burner may be regulated by means of a damper 20 arranged at the mouth of the air pipe 11 and consisting of a plate of sheet metal (Fig. 2) adapted to be operated from the outside by a handle or lever 21.
I claim as my invention 1. In a gas cooker, the combination of a casing including a top plate; a cooking chamber within the casing; a fiameless combustion burner within said casing for heating said top plate and said chamber; a block of refractory material disposed directly above said burner and between the latter and the top plate; a depending draft chimney connected to the bottom of the burner and communicating with the same, said chimney being open at its lower end for ingress of air and adapted to be heated by radiating heat from the cooking chamber so as to cause a current of air to enter and flow through the chimney into the burner; and means for supplying gas to said burner for admixture with the air.
2. In a gas cooker, the combination of a casing including a top plate; a flameless combustion burner within said casing; a pair of ovens within said casing at opposite sides of said burner to be heated thereby; a block of refractory material disposed directly above said burner and between the latter and the top p1ate;'a depending draft chimney connected to the bottom of the burner and communicating With the same, said chimney being open at its lower end for ingress of air and adapted to be heated by radiating heat from said ovens so as to cause a current of air to enter and flow through the chimney into the burner; and means for supplying gas to said burner for admixture With the air. 10
In testimon whereof I afiix my signature in presence 0 two witnesses.
