` s claims. (Cl. s- 118) This invention relates to air shutters for double burners for gas range cooking tops, and consists of an advantageous arrangement of a larger shutter for the large section of such a double burner in combination with a shutter or smaller shutter for the small section thereof.
'Ihe object of this invention is to provide perfect control of air for each section of a gas range double top burner.
Another object of this invention is to provide such shutter means as to be suitable for equipment on the space provided on the usual double top burner.
Another object of this invention is to provide perfect adjustment for a double top burner without the 'necessity of a secondary loriiice in the nozzle hood for the small burner section as disclosed in my copending application Serial No. 396,522, filed October 3, 1929.
These and other objects of this invention will be more apparent from the following description and from the drawing in which- Figure 1 is a top view of a double gas cock and burner equipped with shutter means of the type of this invention; Y
Figure 2 is a side elevation of the same, the burner and shutters being shown in section;
Figure 3 is a front elevation of the mixeiace on the double burner;
Figure 4 is a front elevation of the inner large shutter; and i Figure 5 is a front elevation of the outerlarge shutter.
Referring now to the drawing, a double burner 10 is shown having mixing tubes 11 and 12 leading respectively to burner sections 13 and 14 each having burner ports 15 therein. A gas cock 16 is shown having nozzles 17 and 18 projecting into respective mixing tubes 1l and 12. These nozzles 17 and 18 also project through an inner shutter 19 and an outer shutter 20, which are clamped to the mixer face 2l of the burner 10 by means of the clamping screw 22. The mixer chined with a suitable surface to accommodate .33 clamped thereon by means of. the screw 34 face 21 is a portion of the burner which is mailxed position by the two aforesaid nozzles as well as by the clamping screw 22. f
In Figure 5, the outer shutter has a central opening 28 through which the nozzle 18 projects, and it has a circularly slotted portion 29 accom- 60 modating the upper nozzle 17 and also accommodating the screw 22 in its narrowed section 30, said openings being slotted on a radius from the center of the shutter so that said shutter 20 may be rotated to a considerable extent even though the screw 22 and the nozzle 17 project therethrough outside of the center of rotation. 'Ihis shutter 20 has also rectangular shaped openings 26a and 27a for admissionl of air to the mixing tube 12, and these openings 26a and 27a are so placed that'in one rotary position of the shutter 20 they are in register with the corresponding openings 26 and 27 in the inner shutter 19 thereby admitting air to the mixing tube 12, and in another rotary position of the shutter 20 these openings 26a and 27a are entirely out of register with the corresponding openings 26 andT 27 in the inner shutter 19, and in such position air entrance is entirely cut off from the mixing tube 12. And in between these two rotary positions of the outer shutter 20, it can be seen that intermediate adjustments may be obtained of the air supply to the mixing tube 12. Since the nozzle 17 is a close iit in the hole 23 in the inner shutter 19, and since the openings 26 and 27 are both placed below thedivision wall 31 separating the two mixing tubes 11 and 12,- it can be seen that in all the rotary positions of the shutter 20 substantially no air is admitted therethrough to the small mixing tube 11. 1
For the purpose of admitting air to the small mixing tube l1, an auxiliary mixing face 32 is provided on the side of said mixing tube ll, and said mixing face has an auxiliary circular shutter which is tapped into the burner casting' at 35. This auxiliary shutter 33 is provided with an air opening 36 designed to register with a corresponding opening 36a ,in the mixer face 32 in one rotary position of the auxiliary shutter 33, and to be entirely out of register with said openingin another rotary position of said auxiliary shutter 33. And in this /shutter also intermediate adjustmentsof air to the small mixing tube 11 may be obtained by intermediate rotary positions of the auxiliary shutter 33. It should be noted that the maximum air opening of the ports 36 and 36a may bevdesirably made very much smaller than the air openings-26, 27 and 26a and 27a,
due to the former controlling air adjustment toA 1 10l a very much smaller burner section than the latter.
From the foregoing it can be seen that I have provided a means of obtaining exact air adjustment as required of each section of a double burner, one sectionbeing adjustable independently of the other.
While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes 'in form and thel proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing fromthe spirit or scope of my invention.
I claim: 1. A double gas range burner having two mixing tubes therein, each of said mixing tubes leading to a separate burner section having burner ports therein, said burner sections being arranged within the area covered by the usual cooking vessel, a gas cock having two gas nozzles thereon,
each of said'nozzles projecting into one of the aforesaid mixing tubes, said mixing tubes each having independent air adjusting means, said means comprising shutter means through which both of said nozzles project, and additional shutter means removed from said nozzles;
2. A double gas range burner having two mixing tubes therein, each of said mixing tubes leading to a separate burner section having burner ports therein, said burner sections being arranged Within the area covered by the usual cooking vessel, a gas cock having two 'gas nozzles thereon, each of said nozzles projecting into one of the aforesaid mixing tubes, said mixing tubes each having independent air adjusting means, said means havng a member through which both of said nozzles project 3. A double gas range burner having two mixing tubes therein, each of said mixing tubes leading to a separate burner section having burner ports therein, said burner sections being arranged within the area covered by the usual cooking vessel, a gas cock having two gas nozzles thereon, each of said nozzles projecting into one of the aforesaid mixing tubes, said mixing tubes each having independent air adjusting means, said means comprising a substantially circular shutter composed of two parts through both of which both of said nozzles project, and an auxiliary shutter positioned on the side of one of said mixing tube means.
