yGASeEurEmrirlvG SYSTEM Application filed March 17, 1914. Serial No. 825,261.

To all whom it may concern:

Be it known that I, CHESTER E. CLARK, a citizen of the United States, and a resident of the city of New York, Tompkinsville,

borough of Richmond, county of Richmond2 and State of New York, have invented a new and Improved Gas-Generating System, of which the following is a full, clear, and exact description.

This invention relates to improvements in gas generating systems, and has for an object to provide an improved structure which may use crude oil or any desired oil, and produce a gas easily transported and ready for use at all times.

Another object of the invention is the provision of an improved structure wherein the same works under pressure maintained at a certain tension, whereby a certain mixture of gas is produced continually, according to the way the device is set to operate.

A still further object of the invention isv to provide a generating system which will generate gas that may be stored and transmitted any desired. distance without deterioration, said gas being generated from heavy oils, as for instance crude oil.

In carrying out the object of the invention the same may be associated with various devices, as for instance an ordinary explosive engine. When associated with an explosive engine the manifold or exhaust tube is. utiv lized so that the heat from' the exhaust will heat the oil to the desired temperature so that the same may properly mix with the air supplied thereto at a proper point. The supply tank is provided with any desired quantity of oil, and is then connected to asuitable pump which maintains a predetermined pressure of air'in the tank. This causes the oil to be fed from the tank and also provides an air supply which is utilized in making the gas. The oil from the tank is forced through a suitable pipe inclosed in a housing, said pipe and housing being arranged in the manifold of the engine.

mixing device or generator is connected with the oil pipe extending through the manifold and with an air pipe extending from the supply tank. These two pipes discharge heated oil and air, respectively. The air is caused to flow or be discharged across the spray or discharge of oil, whereby a perfect mixture is produced, the discharge being made in a suitable mixing chamber provided wlth a refuse compartment, and with a discharge outlet. From the lmixing chamber the air passes through a suitable filler 'into a storagechamber, and from thence to the explosive eng-'ine or other point of utilization. It is to be noted that the generating device causes a proper mixture of the air and oil to produce a proper explosive gas when the device is to be used on an explosive engine, such gas being adapted to be exploded without the extra mixing of additional air by a carbureter or other similar device. Then the gasy is to be used for heating purposes or for any other purpose the generating device is readjusted so as to produce a proper mixture for the( oil used in order to provide a proper gas for heating or for any other particular purpose desired.

In the accompanying drawings-Figure 1 is a top plan View of an explosive engine, an embodiment of the invention being shown connected thereto, certain parts being in section; Fig. 2 is an enlarged detail sectional view through a generating device; Fig. 3 is a section through Fig. 2 'approximately on line 3 3.

Referring to the accompanying drawings by numeral, 1 indicates an explosive .engine of any desired kind rovided with an air pump 2, also of any esired kind. The engine 1 is provided with the usual manifold 3 through which the exhaust is discharged.

Manifold 3 is provided with an extension 4' for accommodating certain' parts of the ,in-

vention said extension 4 being-connected with a suitable muier, if desired. Arranged at a convenient point is a supply tank 5 in which oil 6, preferably crude oil, is placed.

Pump 2 is connected through suitable pipes4 to tank 5' so as to supply the same with comressed air, a check valve 7 being interposed 1n,said` pipe so as to prevent any reverse movement of the air. A relief valve-8` is also provided which may be set so that pump 2 can only maintain a certain pressure in tank 5. An oil discharge pipe 9I is connected with tank 5 and extends to near the bottom thereof.- This pipe has connected therewith pipe 10 which has a section 11 extending through the manifold 3'and extensions 4. In order that the exhaust will not heat' pipe 11 in spots or cause a sudden heating of the oilby the intermittent discharge of the exhaust, a housing 12 surrounds section 11 to near the discharge point, as clearly shown in Fig. 1. The section 11 of pipe lO'is provided with a valve 13, which valve has an operating shaft 14.

Connected to shaft 14 is la crank 15 having- 24. Chamber23 is in free communication j with a section 11 of pipe 10, which section is tapered at 25 so as to give a spray eect to the discharge into chamber 23. Chamber 23 is provided with an opening 26 adapted to accommodate the needle valve 27, which needlevalve may have a handle 28 for operating the same, or may be provided with a squared portion or other suitable means for receiving a tool, whereby theneedle valve may be adjusted. The needle valve 27 is provided with threads 29 so that upon a rotation of the valve the same will be opened or closed. rlihe opening 26 discharges directly into the mixing chamber 30, while the opening 31 from the air chamber 24 discharges into the mixing chamber through an inclined passageway 32, whereby the air is discharged into the spray of oil at a tangent and thereby mixes more quickly and in a better manner. 1t will be noted that there is a short passageway 33 through which the air and oil spray must pass before entering the mixing chamber 30. This also assists in causing a more perfect mixing of the air and gas. rlhe air opening ..31 coacts with the needle valve 34 which is constructed similar to needle valve 27 and therefore will need no additional description.

The air pipe 20 discharges air into chamber 24, which chamber is preferably comparatively small, and which chamber is also preferably provided with an air' pressure substantially equal to the air pressure in tank 5. rll`he pressure of the oil in chamber 23 is also substantially equal to the pressure in tank 5 so that the oil spray and the air sprayis of substantially equal pressure. lt is of course to be observed that the oil passes through the manifold before it passes into the chamber 23, whereby the same is in a more or less gaseous or vaporized state.

lt is also to be observed that this oil supply is heated to the desired extent for quickly mareos i mixing with the air, the air being more or upwardly through the discharge member 40.

and from thence through check valve 41 and then pipe 42. A hand operated valve 43 is provided in pipe 42 so as to manually shut olf the gas from chamber 30'whenever desired. rlihe check valve 41 is designed to prevent the reverse flow of gas from storage tank 44. It will be observed that a wire mesh member 45 is arranged in the discharge opening 40 and a iltering medium 46 is arranged adjacent the wire mesh. The filtering medium 46 may be asbestos or asbestos wool, as desired. From the storage tank 44 the gas is led through pipe 47 to pipe 48, and from thence through check valve 49 to the throttle valve 50 of engine 1. A. relief valve 51 is provided adjacent the throttle valve 50 so that if the throttle valve was suddenly shut off the gas may escape without doing injury to various parts. Connected with pipe'40 is a by-pass or return pipe 52 provided with a check valve 53 and a hand operated valve 54, pipe 52 connecting pipe 48 and mixing chamber 30. rThis pipe is to relieve the mixing chamber 30 of excessive pressure. lln'order to accomplish this relieving action when the pressure in chamber 44 reaches a predetermined extent no more of the explosive mixture will pass therein, but will pass into pipe 52 and through valve 54 which is normally open. From valve 54 the explosive matter will pass through the check valve 53, and from thence to pipe 48. From pipe 48 the explosive matter passes through check valve 19. either to the engine or to the relief valve 51. llt will be noted that the explosive matter in chamber 44 not discharged, will not be raised beyond a certain pressure.' In order that the supply of air and oil may be automatically shut off a piston 55 is provided and is arranged with one face in free communication with chamber- 30, and is adapted to operate in a cylinder 56. Normally spring 57 holds the piston 55 in the position shown in Fig. 1, but when pressure in the chamber 30 .exceeds a certain limit. the piston will be moved against the action of spring 57 and consequently will raise the piston rod 58 and swing the lever 59 'so that link 16 will be moved longitudinally, whereupon valves 13 and 19 will be closed. llt will of course be evident that the closing/of these valves may be done quickly or slowly, or that thesev valves may be only partially closed so as to supply a small quantity of fuel. When the engine 1 is stopped thepressure in chamber 30 and chamber 44 will increase until the same reaches the maximum, after `which thepi'ston 55 will be moved for shutting 0H completelythe air and the oil. x

The-invention has been'described in connection With an explosive engine, and the illustrations have been shown connected with an explosive engine, but it will beevident that the system offprovding 'an equal pressure throughout and the various detailed. structures couldbe used separatelyl from the explosiveJ engine for providing a gas from'crude'oil or any other oil containing hydrocarbon. By feeding air to the generator from tank 5 the climatic changes and conditions Will not produce any effect upon the quality of 'the gas orl the action of the explosive` engine or other device to which the gas is supplied. Where an ordinary carbureter is used air is taken from the surrounding atmosphere, and by reasonv of this factthecarburetermust be readjusted every:

time the air changes. By using a supplyof compressed air, as above described', the ordinary 'climatic changes and the condition ofthe surrounding air Will not in any Way proper mixing ofthe gases and the 4 properfaction of the gases' when used.

When the, system is 4used independently of an explosive engine any desired means may be provided for supplying heat to the tulou-i:v

v ylar member or manifold 3. When using the gas for'an explosive engine'the needle valves 27 'and jlare adjusted to produce a proper mixture of air and gas, or in other Words a vproper Vexplosive mixture forthe engine Without .the'engine 'drawing ina supply of airl from the vsurrounding atmosphere. When the gas is to be used for heatingpurposes, vas-for instance in a stove, the needle valves 27' and 34 are again adjusted so as to produce 'a proper lburning gas.

the needle valves are once set for'thel particular. mixture they are left in that position continually as the oil isfed thereto at a continuous equal pressure and the air is fed" theretoat a continuous equal pressure, ,said air being ofcontinually the same characteristi'cs. partially vaporized oil with the 'air in a heated condition, filtering the same and then drawing the same from a storage chamber, a gas is provided which may be transmitted through pipes any desired distance Without detriment, or may be stored for `any de sired length of time.
