2 Claims.
It is an object of this invention to provide a fluid fuel burner having vtwo principal parts that determine the size of the burner opening, and which size is fixed by two planar surfaces, one
on each part.
The'burner is designed to be of the ribbon flame type, wherein the flame comprises a continuous band around the periphery of the burner.
A further object is to provide a burner of this l0 type wherein means is provided to elongate certain ports to prevent flash-back.
A further object consists in lthe manner of manufacturing the burner, such as set out in the accompanying specification, and wherein two important steps consist in providing two principal parts for the burner, forming a single reference surface on each, and using said reference surfaces as means for determining the dimensions of the burner.
In the drawing:
Fig. l is a section on the line I-I of Fig. 2.
Fig. 2 is avertical section showing one form of burner.
Fig. 3 is a vertical section showing a second form of burner.
Fig. 4 is a sectional view showing a third form of burner.
Referring to the type shown in Figs. 1 and 2, theburner comprises a bowl I0 attached to a mixing tube I I, that may extend out and be controlled by a gas cock or any such valve and a shutter to admit primary air. The bowl has a central upstanding cylindrical portion I2, and an outer wall I3 terminating in a flange I4, the upper surface of which, as at I5, is'machined to be perfectly fiat. Resting upon surface I5 is a spacing device I6 n having spaced prongs thereof extending radially outwardly therefrom. It is these prongs, here shown as three in number, that engage the upperl surface I5 of flange I4, the ring portion being spaced back from this flange. fingers I1 is a cap member I8 having a flange I9, the under surface o f which at 20 is manufactured to be smooth and planar. Thus the spacing of surface 20 from surface I5 is Agoverned entirely by the thickness of fingers I1 of'spacer member I6. Capv member` I8 has. a depression centrally therein which provides substantially vertical walls 2|. The depression terminatesin' a vertical cylindrical portion 22 adapted to t within cylindrical. portion I2 of the burner bowl. This fit is preferably close", and centralizes the cap in the bowl to hold the parts in proper relation. Portion 22 terminates in a threaded end over which is engaged a locking nut 23 that holds the burner Resting upon the together. It will be seen that a secondary air passage is provided through cylindrical portion 22. Pressed or otherwise secured to the cylindrical portion of cap I8 is a ringlike member 24. In member 24 and portion 2| is provided a series of outlet ports 25. Ports 25 give an inner flame for the burner to cooperate with the ribbonlike flame supported between surfaces 2l) and I5 to increase the efficiency of the burner. The use of ring 24 provides an elongated slot at 25 that reduces the possibilities of the back flash of the ame into the bowl and mixing tube.
f In the construction of this burner the bowl I0 is manufactured and with a single grinding or other `machine operation, the surface I5 is made smooth and planar. Cap member I8 may be made by a stamping. In its manufacture the surface 20 is made smooth and planar. Thus in the construction of the burner there are only two surfaces producable by only two operations with a single machine adjustment for each; and these two surfaces absolutely fix, with the use of spacer member I6, the size of the outer burner slot and also provide the slot itself. It will be seen that the slot is continuous and the pointed fingers I1 are so spaced and dimensioned that the outer flame issued between surfaces 20 and I5 will be a continuous ribbon around the burner. It isl for ject to dislocation, should such be possible after a pressed t. Furthermore, the burner has better appearance with this element concealed.
With ring member 24 on cap I8, spacer ring I6 is dropped into position with the fingers I'l resting on surface I5. Cap member I8 is then put into position with cylindrical portion 22 extending through cylindrical portion I2 of burner bowl I Ilfand the locking nut 23 is fastened. It will be observed that the spacing of the outer burner slot is entirely unaffected by the degree of tightness of lock` nut `23.
The burner of Fig. 3 is similar to that of Fig. 2. In this burner, however, lugs or bosses 30 extend inwardly from wall I3, and there should be aty least'three of these.
At lthe time of the surfacing of surface I5, the upper ends of. lugs 30 are simultaneously made coplanar with surface I5, this being done in a single operation. Cap member Il is pressed or otherwise formed to have a lower surface 3l spaced from surface 20 by exactly the desired dimensions of burner slot 32. The surface 3l -f may be provided in the same stamping operation by which a cap'member I8 is manufactured. Thus in the assembly of this burner the spacer ring I6 is eliminated. Other than these noted differences the burner is identical with` the burner in Fig. 2.
ber I8, depressions 40 are pressed or otherwise formed in flangeV member 4I, these depressions 40Y extending outwardly from the under surface 20 by a predetermined distance, which distance is the deciding spacing for slot 42. It will be seen that this burner requires only two machining operations to determine the width of the slot opening.
It will be observed that in all of these burners the manufacture of the burner bowl necessitates a singleioperation that requires xed dimension'- ing. The burner bowl may be a single casting with the mixing tube as shown, thus materially simplifying this structur. After the bowl is cast it may be held against a grinding wheel or the like and the surface l5 made smooth and planar to fix simultaneously the slot surface and the reference surface thereof. Where the manumembers may have all of their fixed dimensions provided ina single operation, preferably in a stampingVY or die-casting machine.
Having described the burners, what isrclalmed 1. A burner comprising a bowlY member having an annular planar upper surface of substantial width and a. centrally located hollow tubular portion, a cap member having a planar surface of substantial width cooperating with said bowl planar surface to provide a substantially horizontal annular burner slot, said cap having a vertical cylindrically recessed central portion extending into said bowl to provide an annular passageway in communication with the burner slot and a cylindrically hollow tubular portion-telescopically fitting said bowl tubular portion, and radiallyV extending spacing means between said planar surfaces, said -rneans having their outer extremities positioned a substantial distance inwadly of the outer edges of said surfaces and tapered to a sharp point in the direction of flow to permit the free flow of' fuel in a continuous ring adjacent the outer edges of said planar surfaces to provide a continuous flame at the burner slot.
2. A burner comprising a bowl member having' tapered to a sharp point Ain the direction of ow to permit the free iow of fuel in a continuous ring adjacent the outer edges of said surfaces to` provide a continuous flame at the burner slot.)
