(Cl. 158-91) l Our invention relates to an improvement in Pilot devices for ,pot type burners. It has for one purpose to provide an improved device for maintaining a low or pilot ilamein a Dot type Vburner during periods when -the heating demand Another purpose is to provide. a pilot attach` ment or structure lor pot type burners which provides silent combustion:
Another purpose is to provide a pilot structure for pot type burners which operates with a minimum of free carbon deposit.
Other purposeswill appear from time to time in the course of the specication.
We illustrate our invention more or less diao Y z l derstood that the volume or rate oi flow oi fuel admitted along the fuel pipe I0 may be manual- 'ly or thermostatically controlled to provide a re1- atively small iiow loi fuel at the pilot stage and a larger ilow of fuel when the heating demand rises.
'lhe upper space within the housing l above the ring l serves as a combustion chamber. The
open top of the pot 1 may .be .partially closed'by any suitable llame ring, Il, with va central aperture I2. The wall oi the pot 'l is provided with A a plurality 'of primary air inlet apertures I3, lo-
cated at various levels, the lowest row being shown as downwardly tilted. Anysuitable means may be employed for admitting secondary air at or adjacent the top of .the pot. We illustrate for example a row' of secondary air inlets il, which are more closelyspaced than the inlets I 3 and grammatically in the accompanying drawings wherein: v Figure 1 'is a vertical axial section;
Figure 2 is a section on the line 2-2 of Figure 1;
Figure 3 is a section on the line 3-3 of Figuro 1;`
Figure 4 is a similar section through a variant form oi the device; y
Figure 5 is a section on the line-5 5 of Figuro Figure 6 is a section on the line `6-6 oi Figuro 5.
Like parts are indicated by like characters throughout the speciilcation and drawings.
Referring .to the drawings, l indicates any suitable heater outer housing or drum, herein illustrated as being mounted on legs 2, which provide air inlet spaces 3. 4 is a bottompartition having a central air inlet aperture 5 whereby the atmospheric air which passes through the spaces 3 mayenter the space within the housing. 6 is a supporting angle ring mounted intermediate top` preferably upwardly tilted.
It 'will be understood that the entire fuel supply may be delivered to the bottom 9 oi' the pot along the pipe I0. Surrounding the area of admission of the fuel, we provide a pilot piece which includes a pair of generally radialinwardly converging vertical walls It, the inner edges of which deilne, at the bottom, a liquid fuel inlet space or aperture Il. The walls may also be connected by an intermediate arcuate vertical partition I8 provided with an upper aperture I9. 20 indicates a spacer or support for the lower edge of the wall I8 adapted to keep the space I1 open for the passage of unvaporized liquid fuelfrom the space within the pilot piece to the interior'of the pot.
22 is any suitable top plate or cover for the pilot piece. The pilot piece may be held in position forl example by a pin 23, supporting a ring segment 24, the ends vof which are secured to the pilot piece as at 25. It will -be noted that the plate 22 is located at a level above the lowest row of primary air inlet apertures so that air is admittedthrough the wall of the pot 'l into the interior of the pilot piece. e
With references to Figures 4 'to 6 inclusive, we*
may substitute, for the converging walls I6, a single vertical wall 30 apertured to provide leakage space or spaces 3| at its lower edge, the upper central aperture 32 and the top plate 33 located above the lowest ofthe primary air inlet apertures il. 34 is an annular or segmental connecting and supporting element which rests upon the supporting pin 3l.
It will beunderstood as to both forms of the device that additional spacing pins 36 or 36a may be employed in orderto positionand support the pilot piece in proper relation to the 'liquid fuel inlet duct I0. J
It will be realized that. whereas we have 'described and illustrated a practical and operative device. nevertheless many changes may be made in the size, shape, number and disposition of parts withoutdeparting materially from .the spirit of our invention. We therefore wish that the description and drawings be taken as in a broad v sense illustrative or diagrammatic, rather than as a imitation to our precise showing.
