MULTIPLE OIL-GAS GENERATOR DIST;

Application led July 25,

To all/whom it may concer/n.:

Be it known that I, ANDREW DAHLENE, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented anew and useful Multiple Oil-Gas Generator and Distributor, of which the following is a specification.

rlhis invention comprises a device for valiquid fuel such as gasoline, kerosene an the like and distributing it to points of use, and an object is to provide a cheap and simple appliance that will effectively and satisfactorily vaporize such fuels and distribute the vapor to numerous burners.

Other ob'ects are durability and easy operation an cleansing.

The invention is broadly new, basic, and pioneer in that the jet piece is combined with a vaporizing tube, an air mixer and a pressure chamber connected to the air.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detail descrip- Ation and the appended claims.

The accompanying drawing illustrates the invention.

`Figure 1 is a broken diagrammatic plan on a small scale, of an apparatus embodyindg this invention, with parts arranged as a apted for use in a range.

Flg. 2 is a diagrammatic plan similar to Fig. 1, with the burner arranged in a iine commonly a apted for cooking at a counter not shown.

3 is an enlarged fragmental Adetail of arts of the apparatus shown in Figs. 1 an 2.

Fig. 4i is a section on line Figs. 1 and 3.

Fig. 5 is a section on line Fig. 4.

Fig. 6 is a cross section on line Figs. 1, 3 and 4. p

1 is a generating tube, and 2 a distributing head. The tube 1 is supported above the distributor head 2 by brackets 3, 4 secured by stud bolts 5 to said head.

The tube 1 has a threaded end 6 that is connected to a ipe'itting 7 which is con` nected to the va ve 8, of a fuel supply pipe 9 that leads from a source not shown and delivers the fuel under pressure to the tube 1.

The tube 1 is for vaporizing and gasifying liquid fuel, and the distributing head 2 is for receiving'Y and distributing the productsk from the tube. Said head comprises a top vplate ai, an annular bottom plate b, an

inner annular wall o, connecting said plates a and b, an outer annular wall d extending between and connected to said plates a, b and provided with an outwardly extending tubular inlet and air mixing neck e and with lateral distributing orifices f; there being, in the instance shown, six of said orifices, equally disposed on the opposite sides of the neck and inner annular wall c. Said head. is a single casting and its purpose is to receive fuel products and air through the tubular neck e and to allow it to impinge against the inner wall o and to be directed thereby and caused to be thorou hly mixed in the annular passage and irected to issue through the orifices f as occasion may requlre.

The outlet end 101 of tube 1 forms a gas tight fit .in the Socket 11 of the jet-piece casting 12 and is held from rotary or longitudinal movement therein by a set screw 13 and is provided with a reduced port 14 held in register with the bore 15 o stem 16 of the jet piece which comprises the valve casing 17 for needlevalve 18I that controls the nozzle 19, from which the fuel products are directed into the air mixing passa e 20 that opens into an annular chamber 21 1n head 2.

In the top wall of head 2 isa port 22 that leads from annular chamber 21 into an elongated auxiliary vapor and gas distributing chamber 23 that is formed by an inverted elongate trough or hollow cap 24 secured to the top of head 2 by stud bolts 25.

Trough 24 is provided with slits 26 through which vapor escapes from chamber 23 up around tube 1 and is there ignited to heat said tube to vaporize liquid fuel therein.

The auxiliary heater comprises a wall 27 integrally vconnected with Iand extending upward from the top of head 2; and spaced from and surrounding the inverted trough 24, so that between them there is formed a rectangular channel 28. Said channel is partly filled. with an absorbent non-combustible material, as asbestos and is adapted to receive a priming charge of alcohol, which, when ignited, burns for a sutiicient time to heat tube 1 so as to volatilize the liquid fuel therein. rI`he vapor discharges from nozzle 19 with sucient force to cause a current of air to flow through' lthe mixing passage 20 into annular chamber 21 where there is a thorough mixing of air and vapor to form a combustible gas. Part of the mixture passes through port 22 into auxilfifa 'the fuel supply is unexhausted.

The miajor portion of the gas thus formed 4is distributed from the annular chamber 21 through pipes 29 to gas burners 30 that can be arranged in lany desired manner either to surround the vaporizer as shown diagrami matically in Fig. 1 for use in cooking ranges;

' or such pipes can be off-set arid aligned as shown in Fig. 2 for use along a counter. Itli's understood however that my appllance is adapted to other purposes than distributing gas for cooking ranges and heaters and reservation is made to all such uses as do not depart from the scope and spirit of the invention.

To aid in vaporizing the liquid fuel entering tube l, I insert in the tube a solid cylindrical stick of carbon 31 that'is of somewhat less diameter than the tube, so that the vaporizing passageis crescent shaped embracing the top sides and major portion of the bottom of -the'carbon cylinder so that any liquid in the passage will be subjectedv in thin layers to the most intense heat and the Va-porized fuel will be subjected to a less direct heat; ythus avoiding cracking of the hydro-carbon.

Preferably the carbon stick has sharp tapered ends 32 sothat liquid fuel discharging under pressure from the opening 33 in pipe fitting 7 and striking the end of the carbon, Wi.l be broken up into a fine spray that is directed outward against the inside of tube 1.

The carbon stick 31 accumulates considerable heat so that the spray of liquid fuel broken up by its pointed end 32 flows on between two highly heated surfaces so that it will quickl volatilize and gasify.

In case t e tube needs cleaning the casting 12 is `detached and the tube 1 is detached from the fitting 7, after which the carbon stick 31 and any accumulations therein areV removed. The carbon stick mlay then be immersed in a cleansing fluid that will remove the accumulations without affecting the carbon stick'.

In practice, when parts are assembled as described the porous material is charged with alcohol or the like, and valve 8 is opened to permit liquid fuel to discharge into y l tube 1 by gravity or other pressure, and the alcohol is ignited in channel 28 to heat tube 1,` and thereupon the heated gas or vapor discharges under pressure through nozzle 19 into the distributor head 2; after which'part of this discharged vapor passes through the port A22 into auxiliary chamber 23 and through slots 26 to tube 1 and is ignited by the ini-tial flame from the alcohol as herein. I

or Vapor can be directed to any one or all l of the burners 30 as is desired.

' Particular attention is directed to the distributor 2 which as shown consists of two concentric annular walls c, d united.
