La Pointe, Hartford, Conn, assignors, by direct and mesne assignments, to Sunshine Utilities, Inc., a amputation of Rhode Island Application November 15, 1930, Serial No. 495,902 Renewed December 14, 1934 13 Claims.

The present invention relates to oil burners, and has particular reference to oil burners suitable for ranges, stoves, and small heaters, and an object of the invention is to provide a vaporizing chamber below the fuel grooves.

It has been found that oil burners of this type require frequent cleaning, as carbon readily forms in the burner vaporizing chamber during the initial burning. This necessity for frequent cleaning detracts from the usefulness of the burner, and requires care in replacement of the burner parts after cleaning, in order to ensure proper alignment.

One object of the invention is to provide a burner construction which will minimize carbon formation, and which may be readily removed for inspection and cleaning if necessary, and may be instantly replaced in self-aligning position.

Another difiiculty found in oil burners of this type has resulted from the usual construction of feeding the outer burner groove from the inner burner groove, thus producing an uneven flow of oil vapor to the outer burner, and interfering with proper burner operation when set for a low flame. Additional objects of the invention are therefore to construct a, burner which will feed the oil vapor to each of the burner grooves at the same rate, thus producing a steady burning adjustable to any degree ofintensity.

Since the proper. operation and functioning of a burner of this type depends on the proper working and coordination of all the parts thereof,

further objects of the invention include the design of easily controlled flow valves, of a bottle bowl having ample capacity to eliminate oil overflow due to air expansion, of a bottle stand that is sturdy and rugged, and of other parts that fulfill their intended purpose in the best possible manner.

The invention therefore consists of a novel arrangement of parts more fully disclosed in the detailed description following, in conjunction with the accompanying drawings, and more particularly defined in the claims appended thereto.

In the drawings:

Fig. l is an elevation of a general burner arrangement suitable for a stove range, the stove being shown in. section; I

Fig. 2 is a section through the burner on the line 2-2 of Figure 1;

Fig. 3 is an enlarged vertical section through the burner;

Fig. 4 is a perspective detail of the burner seat;

Fig. 5 is a plan View, partly in section, of. the burner stand;

Fig. 6 is a section through an equalizing thimble;

Fig. 7 is a central vertical section through a modified form of burner;

Fig. 8 is an elevational detail of the double valve structure.

Referring to Figure l of the drawings, the burner I0 is supplied with burner oil through pipes ll, !2, a double valve l3 receiving the oil from a supply bowl 14 through a pipe l5 and-controlling the feed through the pipes H, l2. The burner I0 is adjustably mounted on a support stand l6, and the supply bowl I4 is adjustably mounted on a support stand I l. v

The burner construction is clearly shown in Figures 2 to 6, and includes a base l8 which is preferably of cast metal, but which may be of pressed metal if desired, The base l8 may support one or more burner units, the preferred number for range stove use being two; each burner unit has the usual inner fuel groove l9 "and outer fuel groove 20, but instead of a fuel supply from a vaporizer to the inner groove only, the fuel supply is led to each groove by utilizing a low U-shaped vaporizer 2! which has its outlets between the grooves and communicating with the grooves through ports 22 and 23 respectively, and having an inlet 2Ia and a depending cleanout 2lb. Each groove has the usual asbestos wick 24 therein, and has the usual foraminated shells 25, the cover plate 26 and annular cover ring 21 closing the upper portions of the air passageways in the usual manner.

The upper ends of the vaporizer 2| are closed by a metal thimble or the like 28,'shown in section in Figure 6, this metal thimble serving as an expansion chamber for the vapor generated in the vaporizer. The thimble, in certain instances, may have anopening or vent in the upper wall thereof. The thimbles are preferably frictionally held in the upper ends of the vaporizer; and may be readily removed to permit passage of a cleaning tool or brush through the vaporizer.

The center portion of the base is formed as a support element 29, and is rounded so as to universally engage the correspondingly rounded top 33 of a support bracket 3|. The support bracket has a plurality. of radiating arms 32 with threaded bores 33 for receiving adjusting bolts 34 which are provided with the usual lock nuts 35 and engage portions of the base bottom. The bracket has a central threaded opening 36 in the top thereof, and a larger threaded bore 31 at the other end, the bore 31 being adapted to thread on a correspondingly threaded standard 38, and the opening 36 receiving a lock bolt 39 which presses a lock washer 40 into a spherical recess 4| at the upper end of. the support element 29.

The standard 38 is adjustably held in the stand 16, which has a vertical tubular holder 42 for receiving the standard, and a lock screw 43 passing through the holder for clamping the standard in adjusted position. The stand I6 has a base 44 preferably triangular in form, with support legs 45 and a central slot 46 through which a lock bolt 4! may be passed to lock the base to the floor of the stove range or heater.

Referring now to Figures Land 8', the'valve mechanism includes a double valve element l3, receiving oil from the conduit I5 in a central T or fitting 48, which has an upper connection 49 for a vent or as a supplemental inlet, and two outlets 50, 5|, which lead to the needle valves 52, 53. The fitting and its connections are preferably made integral. These needle valves may be of any approved type, but preferably are of the look adjustment type equipped with a toothed control wheel and aspring finger lock. The pipes H, l2 receive the oil from the needle valves and conduct the oil to the vaporizing chambers 2| through connecting nipples 54, which preferably are of the one piece type and have a clean-out 55 at the lower end thereof.

Instead of utilizing a burner base with arcuate vaporizing chambers such as 2|, the burner base may be formed as shown in Figure 7, with vaporizing chambers 59 having straight side passages Ill; this construction permits each side passage to be drilled and threaded at the lower end H, and one side to be drilled and threaded in align ment with the center passage 12, as at 13, for the reception of clean-out plugs, not shown. The center passage is preferably inclined, as illustrated, to facilitate upward flow of the vapor. The passages are therefore easily cleaned whenever cleaning appears desirable. Both constructions of vaporizing chambers have rounded or sloped corners adjacent the groove communicating ports 23, 24, so as to minimize carbon deposition.

The operation of the improved burner may now :be described:

The filled oil bottle being mounted in the bottle bowl, the oil reservoir becomes filled to the proper level, in the usual manner, and the oil feeds through the adjusted and set valve unit to the U-shaped Vaporizers. As soon as burning has started, vaporization of the oil starts in the U- shaped Vaporizers and when the device becomes :heated fully the vaporization takes place in the lower portion of these U-shaped Vaporizers well below the level of the base in which the grooves are formed, and the vapor simultaneously passes out the center holding bolt, for cleaning or any other purpose, it aligns itself as soon as reset on the bracelet top.

While a specific constructional embodiment of the invention has been described, such changes in form, in size, and in proportions as are deemed desirable for different installations may be made, without departure from the spirit and the scope of the invention as defined in the appended claims.
