To all'whom it may conc/ern.'

Be it known that I, BENJAMIN C. SMI'IH,

a citizen of the United States, residing at Bayonne, Hudson county, State of New i Jersey, have invented certain new and ilseful Improvements in Gas Generators and Separator-s, of which the following is a full, clear, and exact description.

-My invention relates to an improved gas generator for forming and supplying gas to f internal combustion-engines, the object of the invention being to provide an improved I constructionv whereby the heavier hydrocarbons may be successfully used in .the above'A Ifboinection. Heretofore great vd'iiici-Ilty has beenexperienced in the attempts that have been made to use the-heavierliquid hydrocarbone, in this connection because it has been Aimpossible to successfully and completely convert the liquid hydrocarbon into a gas beforey it reaches the interior of the engine cylinderwith the result that some ofthe fuel in solid form would be drawn into the cylinder only to burn imperfectly and therebycause the rapid accumulation 'of` carbon on the cylinderkwalls and piston head, to the injury of the efficient operation ofthe motor. By my present improvement I have found a means for effectively overcoming the diiliculties heretofore standing in the way ofi-complete success in the use of such fuel.

In the accompanying drawings, Figure 1 -is an end elevation, partly in section, of

'35 a partl of an engine equipped with myI improvement. Fig. 2 is a relatively enlarged detail view. Fig. 3 is a cross section on the line www.,

1 represents conventionally a motor of the 40 internal combustion variety.

2 represents the exhaust port. 3 represents the exhaust pilpe. 4 represents conventional y an oil feed tank designed to hold liquid fuel at the proper level relatively to the atomiz'er tips 5, which tips are located in `an air passage through which air may rush with a sufficient velocity to draw off, in the form'ofspray,

the proper proportion of liquid fuel to make 6@ the proper gas mixture.

6 is a'pipe leading from the oil feed tank 4 upwardly to a pipe 7 which represents the gas intake pipe of the motor, the same leading to the usual intake port of the m0- tor.' The pipe 6 leads up through the exhaust pipe 3 .so that the hot exhaust gases lwill constantly maintain the pipe 6, at a high temperature while the engine is running. The inner diameter of the pipe 7 is slightly less thanvthat of pipe 6 and the 60 adjacent ends of these pipes are spaced apart with the ends Aoutwardly beveled.

. The upper end of the pipe 6 and the pipe 7 are preferably inclosed within a tubular' jacket 8 above the exhaust pipe 3 to pre- 65 vent the rapid radiation of heat from the v upper end of the pipe -6 and the pipe 7,

where they lead from said exhaust pipei to the head of the engine. The upper end -of,the` pipe 6 is provided with longitudinal 70 slots which preferably are arranged tan-y gentially as shown -in the section Fig. 3, this slotted upper end of said pipe performing the function of a separator as hereinafter described. Within the pipek I pro- 7,5

vide means for imparting a whirling spiral movementto the ascending atomized fuel. In `the preferred form, this means comprises a spiral 9 formed by symmetrically twisting -a stripor plate about its longitudinal y center line with its side edges engaging the inner walls of the pipe.

In operation, the engine, on its suction v stroke, draws` air through the pipe-6. This air enters at the lower end of the oil feed 8'5 i tan-k 4 and passes the sprayer tips 5--5 from which tips there is delivered a spray of the particular fuel used. If this fuel is one of the heavier hydrocarbons, it will not, I at ordinary temperature or even under the conditions incidental to the use of an ordinary gas generator, readily volatilize and, unless-some means is provided to preventit, some of the solid fuel spray is bound to be drawn into the engine Where it will burn, ifat all, only slowly and imperfectly. By my improvement the spray passes through the pipe 6 where in transit a centrifugal action is set up so as to cause the heavier or solid particles of the fuel to impinge against the wallof the pipe 6 where said particles -will lodge and where, by the direct `heat aperture' betn'een'the ten ef pipe 6 end'beeseperated. fi-.om the" gas.; 'which letter 1 flew be' 'thi'.ehgh the"eine' te the Teesidehere` feedd. hy hemel. preeeee 'that 'Seme el the. heaviest hydreeebehs; hithei'te fe-r seeded ee heini-1eme "fer eee n'tfhefeenf [died mee" be emrheed` with .entire Satiseh' 'hy the ese' ef my 'improved enbase- Ii desired.,.e` eleereneeepening' 8 they befprovided@ ere being a damperor mov- 'fdde Slee-Ye eereeihg il'Q there-.fee "fel added, ready Vdeeesje t0,- the Speee Where. the Seperated material aeeumul'ates to enable it to be defined I hdl-fe Dpt dtt'mpld, i0.

By

kvmy improvement, vyhich in the preferred v form includes the" means for causingthe 'centrifugal action within the pipe f6 to occur,

and-'also the use "of a separating means, it-

- s'impossiblesfor solid partszof thefuel to enter the.cylinder. By applying the eX- ternal kjacket 8, the heat lof the pipe 7 is 'maintained so as to prevent condensationof the gas after it leaves the separator.

It should be understoodk that the partienl lar method of heating the pipe 6 shown vherein--that is to say` by the hot exhaust eo,v

gases-'-s merely the preferredl method, since by employingsuch method, the greatest economies can vbe attained. It 'should also be understood that the means for. causi ing the current of air and fuel ,to Whirl for the purpose -of vthrowing any solid particles' or? eontnue'the whirling'action for a `suf-` iicient period toefectivel.' accomplish intended result 0f trees OI-Ihg '.Slbteetiallyall'ofthe-fuel into a'gaseous mixture asdistinguished from'y a mixture in` which Solid .deep-'Si' 01, glilblers' ef fuel, "are Pre-dii# heid, fer .etheewiee the separater weeld discard such asubstantial proportion of fuel asto defeat the ends of economy and successfuloperation. i
