OIL "BURNER,

Application iled October 13, 1924.

The invention relates to oil burners of the wick type and has for its object the obtaining of an improved construction having certain novel features amongst which are first, the provision of an improved casing or container for the burner which is entirely leakproof; second, the provision of an improved construction of a wick actuator and third, the provision of a novel clamping arrangement for the oil inlet tube. rIhese and other features of construction are more fully set forth in the detailed description hereinafter given and illustrated in the accompanying rdrawings wherein Figure 1 is an elevation of the burner with certain parts thereof shown in section;

Figure 2 is a longitudinal section through the axis of the burner;

Figure 3 is a plan view thereof with parts broken away.

The improved burner comprises a cast metal casing 1 having the inner and outer

tubular portions

2 and 3 respectively forming an annular chamber 4 therebetween and integrally connected by means of the bottom wall 5. The inner tubular portion is of lesser length than the outer member and is provided with a machined top surface 6 while within the tube there are the upper and lower cross members 7 and 8 respectively, the upper member being provided with a threaded aperture 9. rllhe outer tubular portion 3 of the casing is preferably of slightly larger circumference at the bottom portion thereof, as indicated at 10, and has an annular supporting flange 11 and the top flange 12. The upper portion of the vouter tube 3 is provided with the smoothly finished internal annular surface 13 for Aguiding ythe tubular perforated wick supporting member 14 to which is fastened the annular wick 15.

16` is a removable cylindrical sheet metal structure insertable within the annular chamber 4 to form the inner guide for the annular wick and as shown, is provided with a cup-shaped head 17 centrally apertured at 18 topermit the clamping screw 19 to pass therethrough and engage the threaded apervvture 9.r The head 17 is strengthened by the downwardly turned flanges 20 thereby -increasing the rigidity of the central cross head. l rIhe removable 'tuforms an'inner guide for bular structure 16 n the annular I abilitythe assembly and disassembly of the wick and by reason' of its'removcontainer having a bottom portion and Serial No. 743,454.

wick in the burner is facilitated. Preferably the member 16 is provided with a. series o f' bracket stops 21 arranged around the periphery of the cylindrical outer surface 22 to form means for limiting the rise of the wick above the top vsurface 23 of the outer casing 1.

At. one side of the casing 1 there is formed an integral housing 24 provided with a longitudinal bore 25 intersecting the annular chamber 4 in an aperture 26. The housing is interiorly threaded at 27 to receive a 'threaded plug 28, said plug being soldered or otherwise .suitably secured t-o la tubular housing 29. This housing forms the bearing for the rod 30 having the gear wheel 31 at its lower end extending through the aperture 26 into the annular chamber 4 and meshing` with the diagonally aligned perforations 32 in the wick supporting member 14. The upper end of the rod 30 has secured thereto, a knob'33 which forms the handle for adliusting the wick.

In order to remove the wick actuating mechanism from the burner casing it is only necessary to unscrew the plug 23 from the housing 24, after which the tubular housing may be moved laterally to disengage the gear wheel 31 from the perforations 32 and then withdrawn outwardly through the housing 24, the entire actuating mechanism being removed as a unit.

In order to clamp the oil inlettube 34 to the oil burner, I have formed the outer casing with an integral' Uehapcd bracket 35 having the threaded aperture 36 therein in alignment with the conical inlet aperture 37 in the bottom member 5 of the casing. The oil inletl tube is provided with a conical nipple 33 preferably secured thereto by soldering or some other means forming a leakproof joint, this nipple being insertable in the conical aperture 37 and adapted to be secured thereto by tightening of the setscrew 39 threadedly engaging the aperture 36 and contacting with the'oil inlet pipe 34 at 'a point diametrically opposite to the nipple 38. The bracket is of substantial height to permit the pipe 34 and the nipple to be inserted in and removed from the bracket and this construction therefore permits Vquick attachment and detachment of the yoil burner from the inlet pipe.
