Application filed January 30, 1918 To all whom it may concern:
Be it known that I, JOI-IANNES Hnnnnm "i VnLsENAAn, architect, subjectof the Queen of the Netherlands, residing at Haarlem,
Netherlands, Koninginneweg 40, have invented certain new and useful Tmprovements in Burners for Gas-Cookers and the like, of which the following is a specification.
The present invention relates to improvements in burners for gas cookers of that kind, wherein means are provided for regulating simultaneously the supply .of gas and air so as to preserve a desired proportion of gas and air at all times.
According to my invention I provide a construction whereby through the Weight of the object to be heated the gas inlet is opened and the ignition takes place by means of a pilot jet (not shown), the regulation of the gas and air supply being controlled simultaneously by means of a single handle, in such a manner that the burner. may burn with. a very low flame without danger of back lighting, this being obtained by moving simultaneously the air and gas openings by means of superposed disks provided with corresponding openings. All moving parts are located inside the burner by which a very simple construction is obtained, while no long movable lever, etc., is placed outside the actual burner, as is the case in existing constructions, and cause damage.
A further object of the invention is the construction of the mixing chamber, through which a perfect mixing of gas and air is obtained. Notwithstanding the very small size of this chamber, the mixing isso perfect that in every position of the regulating handle, the flame always keeps its beautiful green-blue color.
The accompanying drawings show, by my of example, the burner referred to.
Figure 1 is the vertical. section of the burner.
Fig. 2 is the outside View of Fig. 1.
Fig. 3 is the plan view of the air-openings in the bottom of the mixing chamber.
Fig. 4c is a view in elevation of a fragment of a valve rod.
Fig. 5 is a horizontal section of the turnable air slide which rests on the bottom of the mixing chamber.
6 is a plan view of the g: s regnlaton l a plan view at a nozzle.
Specification of Letters Patent.
is also turned around, when the Patented Jan, Mt, train,
Serial No. $1 1,509,
Tn these figures 1 is the wall of the mixing chamber 2; 3 is the gas supply pipe, 4lis the gas valve, 5 is the valve rod, 6 is the spring, which tends to keep the gas valve closed, but which is compressed by the weight of the object 7 to be heated on the valve rod 5, in which position the gas passes through the nozzle 8 and the gas regulator 9, placed thereon, into the mixing chamber. Tn the figures, 10 indicates the air openings in the bottom of the mixing chamber and 11 is the turnable air slide, placed thereon.-
To regulate simultaneously the gas and air inlet, there is a horizontal slit 14 in the side 1 of the mixing chamber, for passing the handle 15, which isfixed to the gas regulator 9, and which passes also through an opening in the air slide 11, so that this slide gas regulator is moved.
placed thereon is provided with openings 16 and wings 17. Two of the four openings '10 in the bottom of the mixing chamber are larger than the other two, so that when the two small openings are covered by the wings 17, part of the larger openings is kept free for air passage. This smaller quantity of passed. air corresponds to the smaller quantity of gas, when the burner is regulated for the small flame by turnin the handle 15. A bad mixing proportion and back lighting are in this way avoided.
The mixing chamber is of a very small size, but the mixing of gas and air therein is very intensive. This is obtained by plac ing on the turnable air slide an air guide mantle 12 of globular form, forming part of said air slide. Air and gas currents are in this way driven together, then strike the underside of the top plate A and flow out of the mixing chamber through the annular slit 13 in the well known manner.
The regulation. of gas is as follows. The nozzle 8 contains, say three, openings 18 and. similarly the turnable regulator, resting thereon, has three corresponding openings 19 of equal size. When the handle 15 is turned the aforesaid openings are made to coincide, the passage of gas is fully opened, and the flame will burn high.
Now there is a narrow circular groove 20 connecting the three openings 18 of the nozzle. When, for burning a low flame, the three openings are closed; however a small quantity gas will. still pass through the openings 19, this quantity having passed through the said circular groove 20.
A small pin 21 and groove 22 are arranged so as to limit the stroke of the handle 15.
All moving parts are locatedinside the burner, and the valve spindle 5 forms the central axis, around which all these movable parts may be turned.
aving now fully described my said invention, What I claim and desire to secure by Letters Patent is:
1. In a burner for gas cookers and the like whereby through the weight of an object to be heated a gas inlet is opened, the combination of a gas supplying head, a valve seat including a nozzle in the end of said head, a spring pressed valve adapted to engage the seat, a valve rod for operating the valve, a gas regulator movable with relation to the nozzle, a mixing chamber inclosing the nozzle and regulator, said mixing chamber having openings for the admission of air, a se1ni-globular air guide mantle having an open end within the mixing chamber and having openings at its opposite end to register with the openings of the mixing chamber and rotatable in the mixing chamber, the said mixing chamber having a slot in its wall and the said guide mantle having an aperture, and a handle connected to the gas regulator and extending through an aperture of the mantle for operating the gas regulator and mantle simultaneously.
2. A burner for gas cookers and the like, the combination of a gas supplying head, a valve seat including a nozzle in the end of said head, a spring pressed valve adapted to engage the seat, a valve rod for operating the valve, a gas regulator movable with relation to the nozzle, a mixing chamber inclosing the nozzle and regulator, said mixing chamber having openings for the admission of air, a semi-globular air guide mantle having an open end within the mixing chamber and having openings in its opposite end to register with the openings of the mixing chamber and rotatable in the mixing chamber and having its upper aperture above the gas supplying jets whereby the gas from the said jets passes upwardly through the said opening, and means for operating the gas regulator and the gas mantle simultaneously.
In testimony whereof I have aflixed my signature in presence of two witnesses.
