.The invention relates to combustion apparatus and refers more particularly to heating apparatus having burners for liquid fuel .of the vaporizing pot type.
The invention has for one of its objects to provide an improved construction of combustion apparatus in which the burner and control are located within the confines of the casing of the apparatus.
The invention has for another object to provide an improved construction of combustion apparatus having a burner and a control for the "fuel supplied to the burner which together form a unit with the control correctly positioned relative to the burner.
The invention has for further objects to provide 'a burner and control unit readily insertable into the casing of the apparatus; to provide an adjustable device for carrying the burner and control unit; to provide the base of the combustion apparatus with a guide for receiving the carrying device; and to provide :an improved construction of carrying device located Within the casing of the combustion apparatus and readily accessible for adjustment.
With these and other objects in view, the invention resides :in the novel features of corrstruction and combination and arrangement or par-ts as more fully hereinafter set forth.
In the drawings:
Figure 1 is a side elevation partly broken away and in section of a combustion apparatus embodying the invention;
Figure 2 is a cross-section on the line 2-2 of Figure 1;
Figure 3 is a side elevation of the burner and control unit;
Figure 4 is a sectional View of the adjustable device for carrying the burner and control unit;
Figure 5 is a cross-section .on the line i5-5 of Figure 4; "and Figure '6 is a sectional view of the control.
The combustion apparatus is a heater and, as illustrated, is a water heater having the vertical water tank I, the concentric casing 2 spaced from the outer wall of the water tank and the base 3, supporting the casing and mounted on the legs 4. The inner Wall of the tank is formed by the concentric tube 5 which extends below the bottom wall 6 of the tank. The space within the tubular inner wall is the combustion chamber of the apparatus. The water tank is supported above the base 3 by means of the supports 1 in the nature of channel-shaped legs, as shown particularly in Fig- 2 ure 2. -The legs engage the downturned peripheral flange of the bottom wall 6 and rest on th base 3. The combustion apparatus also comprises the burner 8 and the control 9 for the fuel supplied to the burner.
The burner is or the vaporizing pot type and comprises the shell [:0 provided with the annular series of primary air inlet holes I1 and I2 in its side wall and with the inlet 13 for the liquid fuel opening into the interior of the shell above its bottom wall 14. The burner also comprises ithe :bafiie l5 and the top wall or cover 15. The baflle .is located between the primary air inlet holes 'M and i2 and rests upon the annular shoulder it! formed in the side wall of the shell and has the central hole 18. The top wall or cover rests :upon the upper edge of the side wall .of the shell and has "the upwardly extending annular flange 19 at its inner edge concentric with the side wall of the shell and extending upwardly within the "tube 5. The top wall .or cover is provided with the annular series of secondary airinlet holes 20. 2| .is a cylindrical ring telescoped within the annular flange I9 and depending therebelow and provided with the annular series of secondary air inlet holes 522. E23 is ta channel shaped ring having its inner iflange encircling the lower portion of the ring 21 and its outer flange adjacent the :side wall of the shell. This latter ring is suitably supported upon the shell above the primary air inlet holes l2 by suitable means such as the studs 24.. The burner is also provided with the lighter tube 25 which is secured to the side wall of its shell above the fuel inlet 5V3.
The control '9 has the float chamber :26 and the ='a'd 'acent liquidiuel outlet chamber 21 which communicates with the float chamber'through the port 28. float chamber :and .30 is the liquid fuel outlet from the outlet chamber. The float 31 controls the level of "the liquid fuel within the lfloat chamber while the valve 32 controls the rate oi flow of the liquid fuel through the outlet to the pipe 33 leading to the burner inlet 13.
The burner and control form a unit with the control vertically positioned relative to the burner so that the surface of the liquid fuel in the float chamber as controlled by the float is at a predetermined height relative to the burner and more particularly the space within the burner shell below its lower baflle and above its bottom wall. Both the burner and the control are mounted on the support 34 which comprises 29 is the liquid fuel inlet to the 3 the plates and 36 to which the burner and control are respectively secured. These plates have the downturned and upturned portions 31 and 38 fixedly secured to each other.
For the purpose of shielding the control 9 from the heat generated in the burner, the guard 39, which is preferably formed of heat resistant sheet metal, is mounted on the support to extend between the burner and control. As illustrated, this guard has the foot flange 40 clamped to the plate 36 by the control. a
The burner and control unit are of a size to be inserted through the opening 4i in the lower portion of the casing 2 and between the supports 1 and, furthermore, to be located within the confines of the casing when in place with the annular flange IQ of the top wall or cover of the burner extending upwardly within the inner side wall 5 of the water tank.
To locate the burner and control unit in 0perative position, the guide 42 is provided on the base 3 and the adjustable device 43 is provided between the support 34 of the burner and control unit and the guide. The guide is channel shaped and has its bottom 44 fixedly secured to the base and further has the terminal portions 45 of its sides inturned towards each other. The adjustable device comprises the angle plate 46, the tubular housing 41 secured to the angle plate, the vertical plunger 48 extending upwardly from the housing, the adjustable plunger 49 within the housing near its other end and the balls 50 within the housing between the two plungers. The angle plate 45 has the foot flange 5i which is longitudinally slidable within the guide 42 and the upright flange 52 extending upwardly between the terminal portions 45 of the guide. The housing 41 is secured preferably to both the foot flange and upright flange by suitable means such as the brazing material 53 and is so positioned that the portion of the housing from which the plunger 48 extends is vertical and the portion of the housing in which the plunger 49 is readily accessible through the openings in the casing and inner supporting wall for adjustment to raise or lower the burner and control unit. As shown the plunger 48 is engageable with or abuts the plate 35 to which the burner is secured in alignment with the axis of the burner. With this construction, the burner and control unit may be readily rotated relative to the tube 5 forming the flue to align the valve 32 with the thermostatically operable rod 54.
