LEON K. BELCHER, OF NEW YORK, N. Y.

OIL-BURNER.

Too whom as may concern:

Be it known that 1, Leon K. BnLoueu. a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Imirovements in Oil-Burners, of which the ollowing is a full, clear, and exact specification.

This invention relates to oil vapor burnera, and one object is to simplify the construction of such burners by casting, the same in an integral piece.

Another object is to improve the heating rower oi the burner and eliminate. smoke JY providing a blue flame. It is also the ann of this invention to provide means for regulating the size of the flame and thereby, control the heat generated. A further object is to produce a burner with a plurality of flame jets, with means for cutting off the gas to one or more of the jets while one or.niore of the other jets are being used. Other objects will appear a the description proceeds. V

."he invention will he lil.\l lu-reiuaftcr de bed in connection with the accompanyili}"dran'ings, which constitute part of this specification. and then more specifically de fined in the claims at the end of the description.

In the accompanying drawings, in which similar reference chara ters are used to designate corresponding parts throughout the several views Figure 1 is an end elevation of a lnirner constructed substantially in :uzcordancc with this invention.

Fig. 2 is a section on the line IL-ll of Fi I 1 2. I n'stead of the several pipes and connect mg elbows enerally used in constructma burners of t is class. an integral casting 1 is used in this case, the samebeing approximately rectangular in shape Wli'll an upper horizontal portion 2. a lower horizontal portion 3, and vertical end portions 4 and 5. The upper horizontal portion 2 has two 1ongitudinal bores 6 and 7 which are connected y a. cross bore 8 at one end. The other end of the bore 6 communicates with a nipple 9 designed to be attached to any source of oil supply, while the other end of the Specification of Letters Patent.

bore 7 communicates with a bore 10 1n the end portion 5 of the casting 1. The lower horizontal portion 3 has a single. longitudinal bore 11 which communicates with the bore 10.-

The burners proper 12 are dotachablv connected to the under face of the upper horizontal portion 2 of the. casting preterably by means of the sliding; dove-tail joints 13 best illustrated in Fig. 3. which permits said burners to be removed for cleaning. repairing or adjustment. Each burner comprising a funnel shaped luul) member 14 having a horizontal annular flange 15 at its upper end. and a disk 16 to lit said flange and adjustably conr ctcd thereto by bolts 17. The upper face of the flange 1:: is dished at i and the disk is correspondingly dished at 19 so that the faces thereof which are presented to each other are parallel. ]l means of the bolts 17 the space between the [tango 15 and disk 16 may be varied to decrease or increase the size of the flame which in use is formed around the top of the burner. l'lach burner is arranged directly over an opening 20 in the lower por tion 3 of the casting". These openings 20 connnunicate with the bore 11 and are 1irected upwardly so that the gas which issues therei'rom is projected into the conical or funnel-shaped passage in the body member 11 of the burner. Owing to the shape of these passages the pdssage of the gas therethrough draws in air with it so that the flame which issues around the top of the burner from the space between the flange 15 and disk 16 is a smokeless blue flame capable of generating a maximum heat. This flame is positioned close below the upper portion 2 of the casting, thus insuring against waste of the heat enerated.

In operation. the oil which is admitted at the nipple 9 passes through the bore 6 over the burners. and then back over them again through the bore 7 Both of these bores are filled with rods 21 which serve to break up the oil andgreatly help in vaporizing it. From the bore 7 the vaporized fucl passes down through the bore 10 to the bore 11 from which it issues through the openings 20 to the burners.

A. vahe 22 is provided in the bore 11 between the openings 20, so thatone burner ii he bore 7.

from the other. Of course, this valve may be opened and both burners need together when desired.

When the oil Suppl is first turned on, a small quantity of in aminable material is placed in the bells 23 which are supported from the under face of the lower portion. 3 of the casting. This inliannnable material is ignited and the flame therefrom will act in place of the flames from the burners to vaporize theoil 'in the bores 6 and 7. The several bores on the casting-are provided with removable plugs 24 at their ends to )ermit cleaning, the introduction of the fill ing rods 21, and other purposes.-

Thecaeting 1 preferably has depending portions 25 below. the lower llmlZOlltnl por-- tion 3 for supporting the device in operative position. The bore 6 may be termed the gas generating chamber, and the bore 7 may be called the gas drying and expansion Lililflh her, for the oil is vapor" ed in the bore 1.; id is further dried an allowed to expand Having thus described my invention, what I claim as new and desire to SQUlllu. by Letters Patent of the United States is:

1. An oil burner of the character described having a gas generating chamber, a burner having sliding interlocking connection With the under surface of the chamber, and means having a gas generating chamber, a burner for supplying gas from said chamber to the burner.

2. An oil burner of the character described below said chamber, said biu ner comprisin r a conically bored body portion and a disc covorin the same, and body portion and disk being dished and having their facing surfaces parallel, means for retaining. the disk in spaced relation to the body Jortion for providing an annular opening; or the liming nildd'llmlllfi for supplying gas to the burner from the gas generating chamber.

3. An oil. burner of the character described having a gas generating chamber, a burner below said chamber, said burner comprising a (sonically bored body portion and adisk for coverin the same, slidinginterlocking connection getween the disk and the under surface of the generating chamber, adjust able means of connection between the dish and body portion for roviding a variable annular opening for 1; ie' liainc. and means for supplying gas to the body portion of the burner from said generating chamber.

4. A. burner comprising a body portion having a central bore, a disk covering the bore at the top of the body portion, and means for retaining thedisk in "epaced relation to the body portion for providing an annular fiaine o ening around the top of the burner, saiddisi: being dished over the bore. and the top of the body portion being correspondingly concaved for the purpose specified.

In testimony whereof I have signeddn name to this specification.
