Serial No. 611,158.

T0 all 'whoml it may concern Be it known that I, FERDINAND I'rrNER, a subject of the Emperor of Austria-Hungary, and a i'esident of Brooklyin-iii the county of Kings and State of New York,

`have invented certain new and useful Improvements in Gasolene-Vaporizers, of

which the following is a specification.

My invention relates t0 iiieans for sup-v is a general central section of apparatus einbodyiilig my invention. Fig. 2 shows in enlargedside elevation the electric heater plug detached from the supply pipe. Fig. 3 is a general side elevation of the fan or rotating element of the `\'apoiizer removed vfrom its position in the apparatus, Fig. 4 is aplan of the vaporizerwith its top plate or in closing dome removed. Fig. 5 is an enlarged central section of the vaporizer taken on a line at right-angles to the view of Fig. l..

1 is a. pipe through which the mixture or gas is supplied to the manifold of a gas engine and'2 lindicates, in slide elevation the outlet end ofa carburetor of any desired vtype employed for the purpose of producing a mixture of air and gasolene or other hydrocarbon. 3 indicates the throttle controlling lever thereof whereby the supply of the mixture of air andgasolenev from the carbnreter to the engine inayfbe controlled.

4 indicates a vaporizcr constructed as will be presently described and having an inlet 5 suitablyconstructed for' connection to the pipeleading to the carhureter and a". outlet G for Lconnection to thc pipe 1 leading to the engine or manifold.l

The i'aporizer is preferably constructed as a casting having an inner shell .4 and outer shell 4 sepa-rated v'by an annular space through which a heating medium such as the exhaust or other heating medium as for instance the Water from the cooling jacket of the engine, may be circulated for the purpose of heating the wall of the inner shell 4',

which wall, as wil e presently described, receives on its inner surfaces the particle-s or drops of any liquid thrown on to the saine by the action of ay dispersing cone or by the centrifugal action of the fan mounted within said inner shell. The heatiiig'medium is introduced into the space" or heating jacket through the inlet 7 and carried away tliere from by the outlet 8 or Vice versa.

Mounted within the inner shell and upon an axis .preferably coincidingpractically with the axis of the shell is a rotatable device 9 in the form of a fan adapted'lpreferably to beself-rotated by the action of the stream of air passing from the carbureter through the vaporizer to the engine. The fan 9 is preferably constructed with its hub e 9 and vancs .cast in one piece and the varies of the fan or fan wheel are .sufficient in number or of sufficient width to practically intercept the wlio-le stream of the mixture and catch upon their surfaces any free particles or drops of gasolene or hydrocarbon therein.' The ranes are inclined to the plane of the fan as shown, 'in order tov cause it to be propelled at a high speed by the action of the stream of the mixture and to throw oti' by centrifugal force the particles or drops'of liquid lodged thereon andcaiise them toI l'come into Contactl with theinner wall of the internal shell 4"or. with parts in direct conducting connectioii therewith. The fan ro- Vtates freely on pivot bearings l0, 10', or is otherwise suitably mounted to rotate in a supporting frame 11. The said frame comprises preferably a ring-1Q having diametrical cross-bars between which the blades of the fan rotate and saidframe is itself mou1ited upon a ledge 13 within the shell 4 and is fastened down in place by an inwardly ex-V tending xflangel 14 on the bottom of the cover or dome 15,as clearly shown in Fig. A5. The under side of the framehas a conical projection 16 ext-ending axially to meet the stream of the mixture iiitroducedthrough.

Ythe Vinlet 5 so as to'throw off against the walls ofthe shell 4. particles or drops of liquid hydrocarbon encountered in the miX- ture or by reason of its heated condition to cause the same to vaporize. `Any particles or drops which do not encounter the conc and pass on tothe fan are received by 4the blades of the letter and thrown off by ceintrifugal action against the heated inner wall of theshell and there vaporized.'

.top vportion or end of the vapo 'By mounting'the fan `in bearings both of which are formedor supported on the frame 11 and properly supporting the same in the rizing chamber with the conical projection extending axiallytoward the inlet 5, with which the pipe leading from the carbureter is connected, it will be' seen that no obstacles are inter d to the free ilow of the mixture and t at the stream is received in a uniform manner by the cone and fan, thus insuring a complete vaporization of the particles in the mixture and avoiding any tendency of the stream to become localized on any part of A means not only is lthe supply of mixture vfrom the carbureter to the vaporizer cut off at will but likewise and at the saine time the supply of they vapor tothe'engine is cut off, so that any residual gas or vaponain the vaporizer cannot pass tov the engine when the throttle controlling the supply from the carbui'etei to the vaporizer isopci'ated.

The pipe or passage 1 between the vapori- Azer and the engine is constructed for the rc# ce'ption of an elect-rie heater plug 20 which may hcfscrewed into the .opening properly formed in the side ofthe pipe l and is pro- .,vided at its inner end with heating electric coil zh/as shown more clearly in Fig. 2, which heating coil takcs'theplace in the plug ofthe ordinary spark points of a spark plug l'and when lheated hy an electric current under control of the driver by means ofa suitable switch, will heat the combustible gas or vapor circulating through thc pipe lion its way to the manifold and engine. The heater plug 20, may he constructed on the plan of the usual spark plug modilied preferably however by extending the centralconducting rod 22 (if the llSllll Splll( plug sufficiently to allow the desired length of heating coil 2l to be wound thereon. The mica or other insulation 23 is extended over the projecting end of the pin 22 to provide insulation of the turns of the heating coil 2l from one another and from the pin, and one end of said coil is attached directly to the end of the rod 22 and the other end of said coil to the pin 24 forming the other terminal or electrode of the plug,

The carbui'ciei operates in the usual inan- 'ner to produce as complete and perfect a mixture of the gasolene and air as is praein the` ready starting of the engine.

lfor this purpow, for altho' the vaporizer has.4 not become thoroughly heated, the driver turns current into the elecrtic heating plug, thus heating the mixture on its way to the manifold and aiding s soon as the saine'is fully in operationl'the electrielieater may be 'electrically disconnected. `In the normal operation or after the engine is fully running, any free pai'- ticles or drops.v of gasoleiie or other hydrocarbon passing lfrom the carhur'eter and'eiiisting in thecentral portion of the stream of the mixture will be caught on the cone 16'and will eventually be vaporized as soon a8 the'same becomes heated up through its 'metallic' connection with the heated walls of the inner-'shell .4'. The outer .portions of the stream or any portions whosemoist particles may not be caupht by the cone, will encounter the varies 0f t ie fan 9, which as Soon as suction is fully established, will re` volve by the action offthe stream of the mixture and at high. speed when the same is mounted on bearings suitably constructed to have little' friction. 'I'hese particles received on the vaues of the fan however, will be immediately dislodged therefrom by centrifugal action and will he thrown against the hot surfaces on the inner wall cf tlievaporizewhieh is new jacketed by Ia layer of het products of combustion received froml the engineer byltlie heated water. taken from the cooling jaclret'thcreof, as may be desired. -The consequence is that all of the gasolene or other hydrocarbon introduced in the carbureter and enter. ing into the mixture, will, if not vapori/,ed` in the earbureter itself, be fully and coinpletely vapoiizcd, thus affording a perfectly dry gas for `supply to the engine through the pipe 1 leading to the manifold. Owing to this complete vaporization, the engine will operate at, a much'higher efficiency than is possible when the mixture is supplied dircct'from the earbureter' and withl consequently la greater.` or less amount of free moisture ofgasolenc in the gas when .it reaches the inanifriiu.

' In the ordinary operation of an automobile engine itis frequently necessary to slow down the engine quickly and for a short period of time, as for instance-,in driving the car through heavy traffic. The operation of the carluireter throttle alone is not effective the throttle may he quickly closed, the engine will not slow down iiniuediately. To aid in slowing down I provide the additional throttle 17 in the .passage leading from the vaporizer to the engine und connect Said thi'dttles S0 that they are opcrpted praetically'as one. This additional throttle operated in connection with the usual cdi-bureter throttle per mite the Aengine to be slowed down almost in- @n Starting the engine and when i staiitly, as by its .means the supply-o luistible gas from the vaporirier to the engine is ell'cctually cut olif. During momentary slowingdowns of the engine by the. opera.- tion of the con'ibined throttle, the fan, being made rather` heavy and being mounted to re- `volvo freely, will continue to revolve at high speed and when the power is turned on suddenly, will be in condition to receiic any free particles of moisture and canse Yvaporization ofthe same .in a manner already de scribed. lit ivill therefore be eeen that a t all times the combustible portion of the gas or mixture will be supplied to the engine in a thoroughly vaporized condition and therei fore in best condition for ellicient operation.

By constructingr the pipe l le.a rlin,,` to the manifold in proper'inanner to receive the electric heater and by using said he; Lin thc manner described, l attain by the nire of one heater practicallyY the saine results that could be obtained by the use oi' a heater plug for each cylinder ot' the engine.

AS will be seen. my invention requires no special construction of carbureter sheli but may be used indi flercntly with carbir reters of any construction, it being neceasary merely to cut the connection from said carbureter to thc engine and interpose the vaporizer between the outlet pipe from the carburcter and the continuation of the pipe leading-to the engine.
