METHOD OF AND APPARATUS FOR FUEL CHARGING AND IGNITING Filed July 14, 1922 I Theobject of this device Patented Nov. 15, 1932 V UNITED STATES CHARLES zoom-or KANE, PENNSYLVANIA i METHOD OF: AND im s U L CIYIVARGING AND-IGNITING Application filed July '14,

1922.. Serial'No. 574,879.

(GRANTED mm rm: CT or MAME a, 1883, As AMENDED APRIL 30,1528; 370 do. 757)" s My method efiiciently prepares, ignites and charges the fuel with its more or less volamany forms of apparatus.

tile constituents, and may practiced with is to provide efii: cient means for confining the fuel under compression, igniting the fuel and discharging the'ignited fuel to a desired source of utilization while in an incandescent state.

Another object is to have the explosion take place prior to the coincidence of the port'in the cylindrical valve with the outletport.

A further purpose'of my invention is to provide a novel construction and arrangement of charge forming and igniting'device' wherein a plurality of explosion chambers are formed within a rotary valve mechanism, so that a constinuous supply of incandescent gasescan be provided.

"which will hereinafter appear, my invention comprehends a novel charge forming and igniting device. i 1 v V I It further comprehends other novel features of construction and advantage all as .will'hereinafter more clearly appear in the detailed description and the appended'claim.

For the purpose of'illustrating my inven tion, I have shown in the accompanying drawing a typical embodiment thereof which is at present preferred by me, since this em- I bodiment will be found in practice-togive satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein'shown and described. r

Referring to the drawing. V

1 designates a casingof-a charge forming and igniting device, embodying my inven g tion, saidcasing being provided .with a water jacket 2 through 'which' a; cooling medium :is

circulated in any desi'redmanner.

Thecasing 1 is provided with a removable end or head 3, which is secured in'position by 3 means of fastening devices 4. Y

5 designates a driving shaft, which is driven in any desired manner, vprefera-bly in timed relation with respect to the mechanism to which the incandescentor ignited gases are* to be delivered. The'shaft 5 is preferably hollow toprovide for a circulation'ofatmosphericair therethrough to prevent the over- 7 V heating of such shaft. This shaft 5 is jour- 2o jWiththe above and other objects in'view shell'8, which revolveswithin the chamber 9 of the casing 1, and which forms rotary combustion chambers. The shell 8 isfpr'o vided with closed ends and an intermediate partition 11 thereby dividing it'into two exspectively.

The valve rality of annular recesses 14, in each of which is seated a sealing'ring 15 which is split for positioning in its said recess where it is fixed in positionby'means of dowel pins 16. I I The sealing ring 15 is'provided with a port 17 which registerswith the resp'ectii e port 18 or'19 formed in thevalve shell 8. These openings lead each other by 180. Each chamber 12 and 13 are provided with an intake port 20 and a dischargeport 21, see Figure T f Each chamber 12 and 13 are provided, respectively in cavities 12A, 13A, supplemental thereto in casing 1, with means for effecting the ignition or explosion of'the charge such as, forexample, sparkplugs 22,-which are controlled in timed relationship in any desired or conventional manner. such as bygenerator 22A, distributor 22B adapted to be shell 8 is provided with a plu-lso I ressure in an desired manner into the ins y 1 v w my present invention, the entire volume of.

take ports 20, and when the valve opening 18 or 19 is in register with its respective intake port, the explosive charge passes into the chamber 12 or 13.

In operation the shaft 5 and the walls of shell :8 become hot so that the #fuel entering inlet port 20, through its associated elongated port 1 7, 18, under pressure :is impacted against hot shaft 5 and deflected into divided streams which are further impacted against the hot interior surface of rotating shell 8,

and thence further deflected to other surfaces :of shell 8. Said impact-ings and deflections continue throughout the degrees of rotation of shell 8 in which said elongated port registers with inlet :port 20 land bringthe fuel :and air admitted through port 20 in contact with substantially the wholeinterior surface of saidshell 8 associated with said elongated port, and. materially reduces the temperature of said .shaft and the walls of shell 8 so that they do-not exceed an efiict ent working temperature.

:Said reduction in temperature causes :a substantial increase in the temperature of 'theiair and'fuel successively impacted anddefiected :as aforesaid and tends :to volatilize the less volatile constituents of said fuel.

' Said successive impactings and deflections of :said fuel and air further creates turbulence materially promotes combustion (and rapidity of flame propagation upon ignition.

After the value has rotated into such position that its port is about to register with its respective discharge port 2'1, the ignition :takes place, and the ignited incandescent gases pass from the discharge port 21to a desired point of utilization.

It will be apparent that while one chamber is having the exploded mixture discharged therefrom, the other chamber is having explosive mixture introduced thereinto.

.I't'wil'l be apparent that 'in accordance with explosive mixture is ignited in a confined space and is then discharged, so that the entire volume of incandescent zgases is discharged .at one time from :an explosion chamher.

If used in conjunction with an internal combustion turbine, the discharge of the ignited gases of the explosive mixture at high veloeity-throughthe passages 21 tends to produce a partial vacuum in chamber 12 or 13 .wherein said ignition occurred, and which tendency is increased by the movement of the or of volatile fuels which can be ignited at moderate pressure 'in contradistinction to heavy fuels which are less volatileand which must be ignited under high pressure.

Special attention is directed to in the valves which, 'as'shown in Figure3,

I prefer to illustrate as about 13510f qport opening, it being apparent that this can be increased or diminished as may be-consid- :ere'd desirable in practice. 'The'dimensions of r, .1

the port opening would depend upon the speedat which the valve mechanism is to be operated. It will be seen that the explosion will take place just prior to the ports 19 and 17 communicating with their discharge port 21-and if a'low degree-ofmixture is-ernployed, the combustion will continue for a predetermined interval with the-op'en-ing of these ports.

a It will :now be apparent that I haveidevised.

the ports.

a new .and useful charge forming and ig- I niting device for light fuels which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in.

the present instance, shown and described apreferred embodimentthereof which glvein practice satisfactory and reliable re- ..sults, it is to be understood that this embodiment is susceptible of modification in various .particularswithoutdeparting from the spirit or scope of the invention or sacrificing any .of its advantages.

The invention herein described may be manufactured and used by and for the Government .of the United States for governmental purposes without the payment to me of any royalty thereon or therefor.

Having thus described my invention, what I claim as new and desire to secure by Let-- ters Patent, is:

A combined charge forming and ignition device for producing a continuous .flow .of incandescent gas under high pressure comprising a casing having a plurality of intake and exhaust ports, a shaft journaled within the ends of the said casing, said shaft :being hollow to permit circulation of a cooling medium therethrough, a rotary shell within the casing having a plurality of combustion chambers, with said shaft extending across each of said chambers in alignment with the flow of fuel from said intake ports each of said chambers having combined inlet and outlet openings, said openings being so related to each other and so related to the exhaust and inlet ports of the casing that the rotation of the shell will produce progressively a substantiall continuous inlet and exhaust for said cham ers and means whereby an ignition spark may beprovided for each of the chambers at about the time its opening registers with an exhaust port of the casing.
