VAPOR OIL-BURNER.

Specification of Letters Patent.

Patented May 11, 1920.

To all whom z't may concern Be it known that we, CHARLES W. TURN- BULL and JOHN H. Fox, citizens of the United States, residing at Albert Lea, in the county of Freeborn and State of Minnesota, have invented certain new and useful Improvements in Vapor Oil-Burners; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

The present invention relates to improvements in vapor oil burners, and has for an object to provide an improved vapor oil burner adapted to volatilize the fuel more efliciently and deliver the fuel to the burner under pressure, whereby the ignitible contents of the fuel are more thoroughly burned and a correspondingly more intense flame produced.

The invention also provides an improved valve for use in connection with the improved vapor oil burner, and which consists in the constructions, combinations and arrangements hereinafter more fully described and claimed.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views:

Figure 1 is a plan view of an improved vapor oil burner constructed in accordance with the present invention.

Fig. 2 is a side view of the same.

Fig. 3 is a vertical sectional view of the improved burner.

Fig. 4: is a plan view of the improved valve.

Fig. 5 is a front view of the same with the parts shown in section.

Fig. 6 is a horizontal sectional view of the same; and

Fig. 7 is a longitudinal sectional view through one of the burners.

Referring more particularly to the drawings, 1 designates a base of suitable construction, preferably an elongated relatively narrow bar having a cross piece 2 at one end thereof and formed at its other end into a wide generating pan 3.

A generating coil 4 is situated above the pan 3 and connects with a vaporizing coil 5 which is supported on the base 1, and has and substantially parallel with the base 1. v

A T coupling 9 is connected to the other end of the vapor cylinder 8, and is adapted to receive other couplings 10 and 11 which carry the two burners 12 and 13.

At 111 is shown the improved combination valve for controlling the passage of the fluid.

The generating pan 3, base 1, and cross piece 2 are preferably all formed in the same casting, together' with a standard 15 which rises out of the pan 3 to support the forward end of the vapor cylinder 8.

Referring more particularly to Fig. 7, 11 represents the T above referred to, which is threaded at opposite ends so that the threaded rear end of the burner nozzle 13 may be screwed into one end of such T 11. The opposite end of the T 11 is adapted to receive a plug 16 which is threaded and screwed therein, the plug having a reduced end 17 also screw threaded to receive a packing nut 18. A needle valve is shown at 19 and passes through the plug 16, T 11, and burner nozzle 13, and is adapted to regulate the flow of the fuel through the open end of said nozzle 13. The valve 19 has a bent end 20 by which it may be grasped and manipulated. By moving the needle 19 back and forth the orifice 21 of the burner or torchlmay be kept clear.

The two torches or burners 12 and 13 are arranged to direct their respective flames at opposite sides of the vapor cylinder 8 and above the vaporizing coil 5, so that the cylinder andl coil are heated and cause the proper vaporization of the fuel before it is allowed to pass out through the torches.

The inner end of the vaporizing coil 5 is provided with a screw threaded opening 22 into which a vertically disposed nipple 23 is screwed, and which in turn is screwed into a right angularly disposed end 24 of the vapor cylinder 8.

The opposite end of the vapor cylinder 8 is also internally screw threaded to receive and a nipple 25 to which the T 9 connects, and a strap 26 passes about the nipple 25 and T 9 and connects to the standard l5 for the purpose of holding these parts in the elevated position shown.

Referring more particularly to Figs. 4, 5 and 6, 27 is a threaded shank of the valve casing which is provided with an oil duct 28 and an air passage 29. This shank 27 is adapted to be screwed into the usual pressure tank. The oil passage 28 connects with an outlet 30 and is under the control of a valve 3l, by which the quantity of oil can be regulated. The air passage 29 also connects with the outlet 30 through a transverse passage 32, the air being under the control of a valve rihe pressure gage 34 is in communication with the air passage 29 and shows the condition of the air pressure source.

The oil duct 28 also has a normally closed outlet 35 extending vertically downward and which is under the control of a valve 3G. rElie outlet 35 connects to a pipe 37 of very small diameter, known as the generating feed wire. This generating feed wire, as shown in Figs. 2 and 3, extends into the generating pan 3 and is adapted to deliver' a quantity of the oil thereto when the apparatus is in cold condition and is to be started. After the delivery of a predetermined amount of oil to the generating pan 3, a match is applied, igniting the oil .which heats the generating coil 4 and vaporizes the fuel therein.

The feed wire 37 is provided with a coni'- cal end 38 adapted to it in a correspondingly formed socket in the lower end of the outlet 35, and a nut 39 surrounds the feed wire 37 and is adapted to screw into the outlet 35.

The valve casing is also provided with an inlet 40, for air under pressure, which is governed by a valve 41.

The outlet 80 of the valve casing is connected by a pipe of small diameter or feed wire 42 which is joined to the outlet 3() in any suitable manner, and at its opposite end connects with the generating coil 4, as shown in Fig. 6. Any suitable connection may be used for this purpose.

The oil from the pressure tank enters directly through the duct 28 and passes in controlled quantity into and through the outlet 30 to the feed wire 42 and generating coil 4, where it becomes heated and afterward passes to the vaporizing coil 5 where it is further heated and vaporized, the vapor ascending into the vapor pressure cylinder S, where it is collected in large quantities before issuing through the burners or torches 12 and 13.

When it is desired to clean the various coils and pipes, the valve 33 may be opened wide to allow air under pressure to pass through the transverse passage 32 and through the outlet 30 to the several coils and through the vapor pressure cylinder to the torches.

It is obvious that those skilled in the art may vary the details of construction and arrangements of parts without departing from the spirit of our invention, and therefore we do not wish to be limited to such features except as may be required by the claims.
