F. M. STARBUCK VAPORIZER FOR INTERNAL COMBUSTION ENGINES Filed April 13 1923 M J 4 J E 5 y Z Patented May 6, 1924,
FIELDING M. STABBUCK, OF SUHMEBSVILLE, WEST VIRGINIA.
VAPORIZEB FOR INTERNAL-COMBUSTION ENGINES.
Application filed April 13, 1923. Serial No. 631,952.
To all whom it may concern:
Be it known that I, FIELmNo M. STAR-- BUCK, a citizen of the United States, residing at Summersville, in the county of Nicholas and State of West Virginia, have invented a new and useful Vaporizer for Internal- Combustion Engines, of which the following is a specification.
This invention relates to Vaporizers for use in connection with the intake manifold of an internal combustion engine.
The object of the invention is to provide a device extending through the intake manifold and connected with the exhaust to provide a heated surface for contact with the fuel entering the manifold from the carbureter whereby the fuel is vaporized and rendered more readily combustible.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made Within the scope of what is claimed without departing from the spirit of the invention.
In the accompanying drawin s Figure 1 represents a side efiavation of a portion of an internal combustion engine showing the intake and exhaust manifolds with this improved attachment ap lied, and
Fig. 2 is a front elevation of t e intake manifold showing it connected with the carbureter, arts being broken out and in sec tion to disclose the attachment constituting this invention. v
In the embodiment illustrated, an intake manifold 1 is shown of usual construction 7 except that the upright leg or pipe thereof 15 made open at its lower end and closed by a nut 2, the'laterally extending tubular arm 3 being connected with the carbureter 5 as shown at 4. Extending through the manifold 1 is a heating device in the form of a tubular member 10 which projects at its opposite ends thro h the manifold, the upper end 11 thereof ing threaded for connection with a flexible pi e 12 which unites it with the exhaust manifold 13 b a coupling 14 so thatthe heated gases rom the exhaust will be fed throu h pipe 12 into pipe 10 and pass out throng its open lower end to the atmosphere. This tube 10 is here shown equipped with a fuel absorbing medium in the form of an asbestos fiber tubular wick 15 which will absorb the fuel admitted from the carbureter, permitting saturation of the wick by capillary attraction. Around this wick 15 is arranged a resistance or heating coil 16 disposed exteriorly of the tube 15 and having one terminal 17 connected to and insulated from the manifold While the other terminal 18 is connected to the tube 10. This wick 15 and resistance coil 16 are similar to those shown in my Patent No. 1,194,437, dated August 15, 1916, and are designed to heat the fuel and vaporize it to facilitate starting of the engine.
It will thus be seen that the tube 10 which is arranged longitudinally in the path of the fuel passing from the carbureter to the cylinder will present a heating surface and t e entering fuel and cause it to vaporize and pass into the cylinder in a readily com-- bustible condition, the heat being supplied,
to said tube 10 after the engine is started from the exhaust manifold in the manner above set forth the electric heating coil which initially heats the fuel to facilitate starting being cut-ofl' by any suitable means, not shown.
Various changes in the f rm, shape, pro-v portion and other minor details 'of construction may be made without departing from the principle or sacrificing any of the advantages of the claimed invention.
The combination of an intake manifold of an explosive engine, a pipe extending through said manifold and adapted to be connected to the exhaust of the engine, a fibrous fuel absorbing tube surrounding said pipe within the manlfold, an electric resistance coil surrounding said tube and connected to initially heat the fuel absorbed by thetube to facilitate starting of the engine the pi e connected with the exhaust continuing t e vaporizing of the fuel after the electric heater has been cut-off.
In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
