CRUDE-OIL BURNER.

Specification of Letters Patent.

Patented May 4., 19315.

Application filed July 25, 1914. Serial No. 853,214.

li ris vaporized and then passed through an airchamber where on leaving it is mixed with an increased admission of compressed air, thus producing a perfect non-luminous flame which is emitted with considerable force at the outlet of the burner tube.

\Vith these and other objects in view the invention consists in the construction, combination and arrangement of parts as will its be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in 'the claims hereunto appended.

Referring to the drawings :Figure' l is a side elevation. Fig. 2 is an enlarged longitudinal section through the burner. Fig. 3 is a top plan view thereof. Fig. '4 is a section on the line 4-4 of Fig. 2. Fig. 5 is a. sect-ion on the line 5-5 of Fig. 2. Fig. 6 is a section looking in an opposite direction.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings by numerals, 1 designates a cylindrical burner tube opening into the atmosphere at one end and hav ing its remaining end closed by a plate 2, the said plate being provided with a circular series of openings adjacent its peripheral edge. The plate 2 is provided with a concentrically arranged boss 3, and passing through the boss and plate is a passage 4;

flared in opposite directions from a point intermediate of its ends. Having screw threaded engagement with the boss 3 is a casing 5 forming an air chamber 6 and is provided with a pair of right angular arranged screw threaded openings and '8 Threaded into the opening 7 is a reducing nozzle 9 having a bore 10 of different dianieters, one end of said bore communicating with the passage through a series of small apertures 11 which have their axes disposed at an angle to the axis of the bore 10, while an 011 vapor pipe 14 communicates with the remaining end.

An oil pipe 12 leads into one arm of a Tcoupling, the other arm being connected by a solid plug to a second T-coupling. An

oil pipe 13 leads from the first coupling to the worm 15, and an oil vapor pipe 14 leads from the worm to the second coupling, the latter having a connecting pipe section leading to the bore 10.

Connected to the casing 5 by a plug 16 having screw threaded engagement with the opening 8, is an air pipe 17 having communication at one extremity with a source air under pressure and at its remaining i atremity with the air chamber 6. A valve 18 is provided for controlling the amount of air fed to the flame, a channel 19 being provided between the head 20 of the reducing.

nozzle 9 and the wall of the passage 4 for allowing the air in the chamber 6 to co mingle with the oil vapor.

A stand 21 formed of metal pipes is provided when the heater is stationary for any length of time, as when the process of heating heavy shafting and expanding hubs of wheels.

The device is attached to a tank containing crude oil, naphthas, oil of tar, vegetable oils or waste lubricating oil and this prodnet is forced with compressed air, of about 25 pounds pressure, into the pipe 12. thence through the pipe around the casing 53 into the worm 15 then back to wherc'the pipe 12 communicates with the nozzle 9. In the reducing nozzle the oil is reduced to a fine stream and is forcibly thrown through the apertures 11 into the interior of the burner tube 1 in the form of a fine spray. This fine spray is ignited and asthe worm 15 becomes heated, the oil which passesthrough it is heated thus forming a gas, which returns to the nozzle 10 and mixes with the auxiliary air where the channel 19 meets the apertures 11 and as a result of the proper feed of oxygen a perfect non-luminous flame is emitted with considerable force at the outlet of the burner tube.

If found necessary a check valve can be positioned in the oil pipe between the burner and the oil tank for preventing back flow of gas or oil.

Having thus described the invention, what I claim is 1. In a burner of the class described comprising a casing having three screw threaded outlets, a cylindrical burner tube open at one end, a plate closing one end of said burner tube havin screw threaded engageinent with one of t e outlets, said plate having a passage flared in opposite directions from a point intermediate of its ends, a re ducing nozzle having a bore of different diameters, screwed into another of the outlets, the bore of said nozzle communicating with the passage of said plate, an oil pipe communicating with the bore of said nozzle, and an air pipe communicating with the in-' terior of outlet.

2. In a burner of the class described, comprising a casin havin three screwthreadsaid casing, through the remaining 7 ed outlets, a cy indrica burner tube open at an oil pi e communicating with the bore of said nozz e, and an air pipe communicating with the interior of saidcasing, through the remaining outlet.

3. In a burner oi. the class described, com-1 prising a casin havin three screw threaded outlets, a cy indrica burner tube open at one end, a plate closing one end of said burner tube havin screw threaded engagement with one of t e outlets, said plate having a passage flared in opposite directions from a point intermediate of its ends, a reducing nozzle having a bore of different diameters, screwed into another of the outlets, a conical head on said nozzle having its passage in the said plate for formingvan inouter surface spaced from the wall of the tervening channel, the bore of said nozzle communicating with the passa e of said plate, through a series of angular y disposed apertures, the outlet of the channel being disposed adjacent the outlets of the apertures, an oil pipe communicating with the bore of said nozzle, and an air pipe communicating with the interior of said casing, through the remaining outlet.

In testimony whereof I afiix my signature in presence of two witnesses.
