To all whom'z't may concern: l l. Be it known that I, JOHN SYKORA', citizen ofthe 4United ]States, residingv at` Windeln, in the county of Cottonwood and State of Minnesota, have inventedv certain new and useful Improvements in Carbureti'ng Apparatus for Internal-Combustion Engines; and I do hereby declare'the following to be a full, clear, and exact description of the invention, such as will enable .others skilled in the art to-which it appertains 'to make and use the same.

My invention has for its object to'provide a carburetlng apparatus for producing hydro-carbon vapor from a. heavy hydro-carbon oil, such as kerosene, for use as a fuel medium for internal combustion engines.

To the above end, the invention consists of the novel'devices andcombinations of devices hereinafter described and dened in the claims. V

The drawing, which is partly in section and partly in elevation, 'illustrates in .a single view thev invention incorporated in the carburetor and the exhaust pipe of an internal combustion engine. 5

The numeral 1 indicates, diagrammatientirety, a carbureter, whicli and the numeral 2 indicates a fuel intake pipe leading from said carbureter to an in.l ternalA combustion engine, only the exhaust pipe 3of which is shown. Gasolene, or other.I light hydro-carbon oil, is conveyedthrou' h a pipe ,4, from any suitable source-of 'supp y, 5.

such as astorage tank,'to the carbureter 1.

A valve casing 5 connects the pipe 4 to the a lever 18, having at its short end a needle carbureter 1, and has mounted therein, a three-way valve of well known construction.

The improved carbureting apparatus comprises a pipe l7, a container 8 for heavy hydro-carbon oil kerosene, and a jacket 9, all of which are concentrically arranged around the zaxis of the exhaust pipe 3. he container 8, as shown, is in the form of a cylindrical shell, spaced apart from the pipe 7 and having an open top and a cast bottom with a flanged internally threaded axialn opening into which the receiving end of the pipe 7 1s screwed. The improved apparatus 1s 1nterposed in the ex- Z, hereinafter referred to as w open V Speeication ofiIietter's Patent.' Patented Mar. 11, 1.919. M 'plication led February 1 6, 1917.` Serial No. 149,009.`

haust pipe 3 and its pipes 7 forman intermediate section ofsaid exhaust pipe. The delivery end of the receiving section of the exhaust pipe v3 is screwed into the cast bottom of the container 8.

The jacket 9 is ofcylindrical form, with an open bottom and spaced apart from the container 8 to afford an air intake conduit c 10, which completely surrounds said vcontainer. A cap 11 closes the upper end of the jacket 9 and-1s provided with a flanged axial opening into which the delivery ends of the pipe arel screwed. The receiving end of the delivery section 'of the Oexhaust pipe 3 is screwed into the flan ed axial openlng of the cap 11'. This cap 11 1s spacedabove the container 8, to afford a mixing chamber 12.

- vA'short fluid fuel supply pipe 13, extends radially through the jacket 9 and connects `the container 8, slightly above its bottom,

with thevalve casing 5. In one position ofv the'` three-way valve 6, the gasolene supply pipe'4 will be open the pipe 13 closed; and in another position to the carbureter 1, and

of said valve,lthe pipe 13 will be open to the j carbureter, and the pipe 4 closed. A combined air' and vapor mixing chamber 12 witI the carbureter 1.

The kerosene Z is fed under pressure, by gravit or otherwise, through a supply pipe 115.lea ing from a suitable source of supply, A.such as a storage tank, not shown, to the con- 'f talner 8. Interposedin the kerosene supply pipe 15, close to` the jacket 9, is a bowl '16, A aving a port'17, into which the delivery end section of the pipe 15 opens'.

of the receiving fulcrumed in the bowl 16 ,is

Intermediatelyl lto close the port 17 .I Obviously, when theV keroseneZ in the container 8 drops below a predetermined elevation, the float 12 will ipe 14 connects'the theneedle valve 19 to admit a furtherl supply ofkerosene and then close the same when the kerosene in the container has again reachedsaid predetermined elevation.

The operationof the improved carbureting apparatus may bel brieiiy described as follows; In starting the engine, the valve 6 is set to close the pipe 13, and open the gasolene supplyy pipe 4. This valve 6 may be operated by any suitable connections, not shown, which preferably extend to the-instrument board, or within easy reach of the driver. Under the suction stroke of the engine, a supply of gasolene `is drawn into the carbureter 1 through the pipe 4, "and a supply of air is drawn into said carbureter through the air conduit 10, mixing chamber 12 and pipe 14. As the pipe 7 becomes heated, 'by the exhaust passing therethrough, the intake of air while passing through the conduit 10 is also heated, thereby greatly increas- 'ing the efficiency of the fuel charge. The

kerosene Z in the container 8 also becomes heated by its direct contact with the pipe 7, and the vapor rising therefrom commingles with the air in the mixing chamber 12, and is drawn into the carbureter 1, through the pipe 14. After the kerosene Z has become sufficiently hot to vaporize, the valve 6 is operated to close the gasolene'supply pipe 4 and open the pipe 13 to permit the kerosene to be drawn, under the suction stroke of the engine, from the container 8 through the Apipe 13, valve casing 5 and into the carbureter 1. With the valve 6 thus set, the

engine continues to run on a fuel chargeof kerosene.

The above described invention, while extremely simple and easy to apply to carbureters of various different makes and to the exhaust pipe of an explosive engine, has in actual usage proven highly efficient fOr-the purpose had in view.

,While the invention is shown in connection with a vertical exhaust pipe,'it is, of course, understood that the same 'may be used in connection with a horizontally disposed exhaust pipe orone that is set at an angle with respect thereto.
