' OIL-BURNER.

To all whom it may concern: .Be it known that I, JOHN NEUMANN, a citizen of the United States, residing at Chicago,inthe county ofCook and State of Illinois, have invented certain new and useful Improvementsin Oil-Burners, of which the following is a description.

. My inventionbelongs to that general class of devices designed to employ crude .oil or any other class'of oil, including kerosene, as a combustible for any purpose. desiredl'It has "fori'its object the'production of such a device :reliable and efficient in its operation and economical'and durablein its construction. 1T0 this en'd'it consists in ltheznovel construction, .arrangement and comblnatlon of partsherei-n shownand described, and "more particularly pointed out in the claims.

In 'the drawings, "wherein like reference characters indicate l ke or corresponding parts,

Figurelis a plan view of my-improved device -taken'from.above, dotted lines indi- .cating the construction and arrangement of 1 parts from; that point of view Fig. 2'isaiside elevation of the same with the parts broken; away to more clearly illustratethe'construction; j

'- Fig.3.-is a centrallongitudinal view of a part of thereceiving'bell for theflame, the transverse view indicating the preferred 1 form of theouterJ-or delivery end thereof;

- "Fig. 4'is a plan view of a modified form of feeding device; and

within the shell andsuitablysup'ported by the bottom,isa vertical tube 5 terminating near its top'in a suitable sleeve 6 and serving to operate substantially as a Bunsen fburner withthevaporized oil as the .fuel. Above thei burner or sleeve 6 issupported atransverseplateW with which the flame from'theburner contacts, servingto heat the Specification ofLetters'Patent.

plate to-a'high temperature and materially aiding in the operation of the device. Ar-

ranged above the plate 7 is a suitable coil ;8

the shell. The fluid combustible is admitted to the coil as at 9 through a suitable tube 10 controlledby valve 11. A short connecting pipe in the form shown in Fig. 1 is indicated at 12, with which communicates a feed pipe 13, communicating with the source of supply. The'fuel is fed underpressure both to the coil and tothe burner '56. The pipe 14 also controlled by a graduated valve, admits a portion'of the incoming fluid through the pipe 12 and conducts the same to a pipe 16,

more clearly illustrated in Fig. 5, which is extended upward and over the flame as at 17, 'substantiallyin line with the plate 7, and thence outward and downward asat 18 and 19, finally delivering'the fluid to the pipe 5 as shown at 20. In the preferred form, shown in Figs. land 2, a partial cloas fire-clay, is positioned above thecoil-8 to prevent the undue escape of heat and confine the temperature more particularly to the coil.

Any prferredmeans may. be employed in initially raising the temperature sufliciently .to start the operation of the device. In the form'shown in Fig.2, a suitable receptacle 22 is placed beneath the bent pipe 19, a

'wick 23 being adapted when lighted toheat the pipe 19 to raise the temperature therein and vaporize the fuel, sufficient air being admitted to insure the proper combustion.

When the incomingfluid is at the proper point of temperature and vaporization, the

Bunsen burner, as at 6, is lighted, directing a flame of high temperature for-the proper operation of the device. The flame from the wick 23 may thereafter be eliminated during fiamesand intensified-by contact with the plate 7, is directed upon the coil 8,bein'g protected against unnecessary, escape by means of the non-combustible plate 21. When the coil is suitably heated,jthe combustible is admitted by-manipulation of the .valve'll through the pipe 10 and to the intake 9, and thence circulatingabout in the upper part of the shell, the fuel becomes heated-"to a'high temperature, finally being so positioned as to be heatedby the flame and-the temperature at the upper part of sure or plate 2-1 of suitable material, such the operation. The heat engendered by the projected under pressure through the end 24 of the coil, through a small jet aperture 25. Whenthis flame is desired for special purposes, as in heating a boiler or in connection with a retort for any purpose, the flame from the jet 25 is directed into the open end of a hell or tube 26, or equivalent device for the purpose, and thence through the delivery end 27, which may be flattened or ovalized as shown at the upper part of Fig. 3, or constructed in other special form for the purpose. A sufficient quantity of atmospheric air is allowed to enter the end 26 of the bell to insure perfect combustion in the operation. As shown in Fig. 2, 28 maybe thewall of any suitable structure, such as the fire-hole of a boiler, or the inclosing wall for a centrally supported retort, and the flame therein-be directed as desired to secure the greatest efliciency during the operation.

Any preferred means may be employed to provide the'supply of fluid to the device under suitable pressure, (not shown). As shown in Fig. 1, the fuel under pressure is provided through the pipe 18, and thence through the feed pipe 10 to the coil and 14 to the primary burner, the amount being regulated by the graduated valves 11 and15.

In the form shown in Fig. 4, insteadof using the short connecting pipe 12 as shown in Fig.1, the fluid is independently conducted to the inlet pipes 14 and 10 by pipes 29 and 30, the graduated valves 11 and 15, or equivalent means, being employed for the purpose of controlling the feed as before stated.

In the form shown in Fig. 5, the coil-8 is not employed, the heat being permitted to escape upward through the upper end of the shell or. otherwise as desired. The fuel is supplied to the pipe 16 as described, the operation bein similar in other respects,

with the exception of the operation incident to the use ofthe coil. In this form a second plate 32 is preferably employed arranged above the plate 7. The heat as it escapes about the margin 7, contacts with the plate 32, which soon reaches a high temperature and aids in the distribution of the heat as it escapes from the device. This form of device is applicable for general heating purposes. Although the coil is not shown as 7 here employed, it is obvious that the devices by Letters Patent is: r

.henceT do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned. 1

What I claim as new and desire to secure 1. A device of the kind described comprising a suitable shell, a burner centrally arranged therein, an inlet pipe providing fuel to the burner, means for heating the fuel passing through the inlet pipe to the burner, and means for controlling the supply of fuel thereto, in combination with circuitous conducting means arranged above the burner, means for controlling a supply of fuel thereto, a burner attached to the delivery end of the circuitous conducting means, and a heat retarding baffle plate arranged above the circuitous conductingv means.

3. A device of the kind described comprising a suitable shell, a burner centrally arranged therein, an inletpipe extended above the burner, Ythence downward below the burner serving as a .feed pipe therefor, and means for initially heatingthe fuel passing through the pipe to the burner, in combination with a conducting coil arranged above the burner, at one end receiving acharge of fuel and. at the other end provided with a burner, a non-combustible heat-retarding baffle plate. arranged above the coil, and a cover for the shell above the plate.

4. A device of the kind described comprising a suitable shell having air inlets at its upper end, a burner centrally arranged therein, an inlet pipe providing fuel to the burner, means for heating the fuel passing through the Einlet pipe to' the burner, and means for controlling a supply of fuel thereto, in combination with a circuitous conducting coil arranged above the burner,
