Description
H. M. REEVES BLUE FLAME BURNER 'Filed July 2, 1938 @f7/70 June 4, 1940.
Patented June 4, 1940 UNITED STATES PATENT OFFICE BLUE FLAME BURNER Application July 2, 1938, Serial No. 217,159
4 Claims.
This invention has to do with burner construction, and is concerned more particularly with a burner construction of the blue flame type.
It is an object of the invention to provide an improved. burner valve construction.
It is a further object to provide an improved burner mounting,
1t is another object to provide a burner mounting comprising separate parts capable of speedy assembly.
A further object is to provide a construction in which a gang of burners is mounted on a common feed pipe.
It is also an object of the invention to provide a burner construction in which the valves are connected to a common feed pipe by relatively short tubes.
It is a further object of my invention to provide a connection between the fuel supply and the valve of a burner, whereby clogging of the fuel line by impurities in the fuel is substantially 0bviated.
Another object of the invention is to provide improved packing for a valve for fuel oil.
Another object is to provide a valve construction which is readily assembled with and separable from the cooperating burner and feed pipe.
` It is also an object to provide a common mounting for one or more burners and associated valves.
A further object is to provide valve structures disposed entirely below the level of fuel in the tank.
Another object is to so mount a valve as to render the cylinder more easily accessible.
Further objects and advantages of the invention will appear as the description proceeds.
The invention will be understood upon reference to the following description and the accompanying drawing, in which:
Fig. 1 is a fragmentary front elevation of burner construction embodying features of my invention;
Fig. 2 is an enlarged section-elevation taken as indicated by the line 2-2 in Fig. l;
Fig. 3 is an enlarged sectional view taken as indicated by the line 3-3 in Fig. 1;
Fig, 4 is an enlarged sectional View taken as indicated by the line 4-4 in Fig. 2; and
Fig. 5 is a reduced transverse sectional View taken as indicated by the line 5--5 in Fig. 1 and showing the assembled casing, burner and tank construction.
Referring now more particularly to the drawing, there is shown at l0 an oil, kerosene or other liquid fuel tank suitably mounted, as adjacent the rear wall of the range casing Il. It could be mounted in back of the casing if desired. Disposed forwardly and within the casing ll is a common feed pipe or manifold l2 Whose ends are 5 plugged as at i3 and supported as on brackets I4, one of which appears fragmentarily. The pipe is connected to the tank as by a conduit l5 and nipple I6. Mounted onthe pipe is a series or gang of burners indicated -generally at l1.
Each burner includes any suitable cylinder i3 formed to rest on the shelf I9 of a burner bowl 20. The bowl 20 includes an annular channel 2l of U-shape in cross section and receiving an annular asbestos or other kindler 22. The bowl has 15 an inner plate portion 24 connected to the top of the inner side of the channel and affording secondary air openings 25. The plate 24 has a preferably central opening 25 through which eX- tends the threaded shank 2'l of a hook bolt 28 20 passing through a hole 29 in the bight 3l of a saddle 32. The bight terminates in seats 33 on which the bottom 34 of the bowl rests. The lower free ends of the arms 35 of the saddle are notched as at 3l to receive the upper side of the pipe I2. 25 The hook 40 of the bolt 28 extends around the bottom of the pipe l2 to engage the pipe in opposition to the saddle arms 36, and a nut 4l applied over the plate 24 and about the threaded shank 2l may be employed to firmly clamp the 30 saddle and hook against the pipe l2, thereby iirmly clamping the bowl I9 on the saddle 32.
A valve structure lembodying my invention for controlling the flow offuel to the channel 2| is shown at 45 and comprises a casing 46 in which 35 is threadedly received a valve rod 4l surrounded by a packing gland, shown generally at 48, and employing a composition of asbestos and graphite, shown at 49, for preventing leakage. This material is particularly effective when, as here, fuel oil, kerosene or the like is used. The rod 4l has a flow control surface 5l engageable with a relatively stationary surface or edge 52, and between the surface 52 and the packing gland the 45 casing has an inlet branch 53. The casing 46 terminates outwardly beyond the surface 52 in an outlet 55 threadedly receiving the open end of a tube 56, the other end of said tube being closed as shown at 5l. The tube 56 has a hole 50 59 in its side adjacent the closed end thereof, and said tube is integrally united with the bottom of the channel 2l, by soldering or otherwise as shown at 60, with the hole 59 in register with a hole 6I in said channel, whereby communication 55,
is established between said tube and said channel.
The valve rod d1 extends forwardly through a front panel or apron 65 of the casing and a handle 66 is mounted on the forward end of the rod forwardly of the panel 65. If desired, an escutcheon plate S1 also may be provided. A front door 68 may be hinged as at 6!! to the frame and urged as by spring means 'I0 to closed position, and has an opening 'H to clear the handle 65 and permit the handle to be operated even when the door is in closed position, as shown in Fig. 2. A nut 'I2 or other suitable means may be employed to hold the handle and plate on the rod.
In order that the valve may be ixedly supported, the apron 55 has an overhanging rearwardly extending flange 13 to which is spotwelded or otherwise suitably secured as at 'lll a hanger I5 extending over the valve casing 46. A U-bracket 1S embracing the underside of the casing il@ has ears T! bolted as at 18 or otherwise suitably fastened to the hanger 15.
A conduit 80 is detachably connected to the valve inlet branch 53 by means of a union 8| and to the feed pipe l2 by a coupling 82 so arranged as not to interfere with the hook d. The valve :l5 is elevated relative to the pipe I 2, so that the ends of the conduit 8l! are at different levels, thereby substantially obviating clogging by stagnation or accumulation of foreign matter from the liquid fuel.
Each Valve (l5 is disposed horizontally so that ample clearance is provided for inserting the hand to raise and lower the cylinder I8. The packing i9 enables the valve to operate even though it is entirely below the level of the fuel in the tank I0.
It will be seen from the foregoing that the burner, while adapted to be securely mounted on the pipe l2 by friction through the use of the bolt 28 and saddle 32, is additionally supported from the pipe through the Valve and conduit 80, and is still further supported independently of the pipe by the front panel or apron 65, whereby the burner is held rigidly in place.
The saddle 32 is preferably a loose piece unconnected to any other part, as is also the bolt 28. The tube is detachably connected to the valve casing 46, the conduit l5 is detachably connected at I6 to the pipe I2, the conduit 8D is detachably connected to the pipe and valve casing and the valve casing is detachably connected to the hanger T5 and handle 66. Thus it is evident that the assembly and disassembly consume but a few moments, yet when the parts are connected they operate efciently as an integral whole.
It is evident that no special machining is required, the various members for the most part being of conventional design or in any event adapted to be constructed very economically.
Various other changes and modifications coming within the spirit of my invention will doubtless suggest themselves to those skilled in the art, and hence I do not wish to be limited to the specinc forms shown or uses mentioned except to the extent indicated in the appended claims, which are to be interpreted as broadly as the state of the art will permit.
I claim:
l. In a fuel oil burner including a burner bowl and means providing a supply of fuel oil, a valve for connecting said means to said bowl, said valve comprising a valve rod and asbestos and graphite packing means for said rod.
2. In a range, a casing, a plurality of horizontally disposed burner bowls in said casing, a cylinder resting on each bowl, a fuel oil tank mounted on said casing, a valve for each bowl and disposed below the level of said oil, a feed pipe between and connected to said tank and said valves, each valve being disposed so as to leave the space in front of the associated cylinder clear for easy access of a hand to said cylinder, said valve having a handle, a front door hinged to said casing and having an opening adapted to receive said handle when said door is closed, whereby said handle may be operated when said door is closed, and means urging said door to its closed position.
3. In a range, a casing, a burner bowl in said casing, a cylinder on said bowl, a valve connected to said bowl and disposed so as to leave the space in front of the cylinder clear for easy access ci a hand to said cylinder, said valve having a handle, a front door hinged to said casing and having an opening adapted to receive said handle when said door is closed, whereby said handle may be operated when said door is closed, and means urging said door to its closed position.
