In order to carry out the present invention it is desirable that the edge of the supporting ange 20 continuously contact the peripheral surface of the outer end of the mixing tube I4 of the burner I3 for the purpose of preventing the passage of air to or from the burner chamber B between the ring 2I and the end of the burner supported thereby. Td facilitate regulation of the damper I9 to control the mixture of gas and air in the burner an opening 24 is formed in the casing I directly in front of the end face of the burner tube I4. This opening 24 is normally closed by means of an imperforate 'cap 25 which is removably secured in the casing I by means of a spring clip 26 secured to the said cap and which engages the inturned flanges 21 on the casing I.
As shown in Fig. l of the drawings, partitions 28 extending between the casing I and the inner wall or lining 2 thereof form a recess in the side wall and enclose the space betwen the opening 24 in the casing and the end of the mixing tube, the said partitions being arranged so that the recess or pocket thus formed extends a substantial distance below the said end of the mixing tube and said opening. The partition 28 at the top of the space between the opening and the end of the mixing tube I4 is cut away to allow for the passage of the gas supply tube I6.
In the present instance a relatively large opening 29 is formed in the plate 22 below the ring 2I thereof for the purpose of affording communication between the enclosed space or recess previously described and the chamber B below the plane of the burner I3 mounted therein.
It will be readily perceived that construction of the oven casing at the intake end of the burner in accordance with the present invention prevents the entrance of fresh air into the burner through the side walls of the casing and requires that all of the air necessary for mixture with the gas in the mixing tube I4 of the burner pass lthrough the opening 29 from a point or points below the burner. In'this manner the pressure or Vacuum at the intake and outlet respectively of the burner will at all times be in perfect balance, and therefore differential pressures or vacua at the intake or outlet of the burner causing fiash back or extinguishment of the burner flame will be entirely eliminated.
The construction of the oven casing previously described is susceptible of numerous ramifications without departing from the spirit of the invention and for the purpose of illustration a modification of the invention is disclosed in Fig. 5 of the drawings wherein the end of the mixing tube of the burner is mounted in a ring 2Ia of a plate 22a. The upper half portion of the circular ring 2Ia is provided with a downwardly projecting flange 2a, the edge of which is arranged to continuously contact the adjacent outer surface of the end of the mixing tube of the burner and prevent communication throughout its extent between the spa'ce at the front of said burner and the chamber B, whereas the bottom of the end 0f the burner is supported in spaced relation from the ring 2 Ia by means of a finger or arm 29a for the purpose of providing openings 29h for communication between the space at the front of the burner and the chamber B below the plane of said burner.
The present invention may be readily adapted to existing gas range constructions wherein the intake end of the burner mixing tube I4 is mounted in an opening 30a in the oven casing I, to permit air from without the oven casing to be supplied to the mixing tube in the customary manner heretofore. In the adaptation of the present invention to this construction, an opening 30 is formed in the oven wall structure below the intake end of the mixing tube I4 as shown in Fig. 6 and this opening 30 and the intake end of the mixing tube I4 of the burner are enclosed by means of a cover or casing member 3| which is hingedly connected as at 32 to the oven casing I to form a recess at one side wall of the casing similar in nature to that previously described. In this manner it will be readily perceived that air entering the intake end of the mixing tube I4 for mixture with the gas fuel must pass through opening 30 from a point below the burner, thereby effectively balancing the pressure or vacuum existing at the intake and outlet respectively of the burner.
Still other casing constructions may be adopted to effectually carry out the invention, and while several forms thereof have been set forth for the purpose of description it is not intended that the invention be precisely limited thereto where within the scope of the annexed claims.
What I claim is:
l. The combination in a gas range structure of an oven; a burner chamber arranged in communication with said oven; a burner in said chamber; a mixing tube extending into said chamber and being connected to said burner; and means supporting the inlet end of said tube in predetermined spaced relation to a wall of the structure; said means comprising a supporting plate attached to said wall and having a ange thereon directed into the burner chamber, said flange being provided with an inwardly directed flange for supporting the inlet end of said tube at the periphery thereof.
2. The combination a gas range structure of an oven; a burner chamber arranged in communication with said oven; a burner in said chamber; a mixing tube extending into said chamber and being connected to said burner; and means supporting the inlet end of said tube in predetermined spaced relation to a wall of the structure; said means comprising a supporting vplate attached to said wall and having a ange thereon directed into the burner chamber, said flange being provided with an inwardly directed flange and a radially extending arm for supporting the inlet end of said tube at the periphery thereof.
