VAPORIZER.
Application lcd September 4, 1923. "Serial No. 660,769.r
To all whom 'it mag/.oofrwcrm Be it known that I, CHARLES W. DUCK- woRTH, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful Improvements in Vaporizers, of which the following is a specifica tion.
My invention relates to vaporizers of the class used for vaporizing the fuels used in internal combustion engines. The main and particular objects and advantages of the invention are: To provide a vaporizer in which the fuel, as it passes through it to the engine, is vaporized by the heat given olf by the exhaust from the engine; to provide means for adding additional 'heated or cold air to the fuel; and to provide means `for thoroughly mixing this added air with the fuel.
A further object is to provide a vaporizer automatic in its operation, simple in construct-ion, small in size, easy to attach to any engine, and comparatively inexpensive to manufacture.
These and various other objects and advantages will be clearly understood from the following specification and from the accompanying drawing of a preferred embodiment of my invention, but it will be understood vthat modifications mightl be made without departing from the scope of the invention. i
Fig. 1 is a side elevation of a preferred embodiment of the vaporizer.
Fig. 2 is a cross-sectional top view of Fig. 1, taken on the line 2-2. Several of the inner tubes having been omitted.
Fig. 3 is a cross-sectional end view of Fig. 1, taken on the line 3-3. Several of the tubes having been omitted.
In the description which follows, the operation of the vaporizer has been explained in connection with a gasoline, automobile engine to facilitate the description, but it will be understood that I do not wish to limit the use of the invention to such engines only.
In a general way the vaporizer may be described as a device placed between the carburetor and the engine; the air and gaso line, after being mixed in the carburetor, enters the `vaporizer where this mixture is heated by passing through a plurality of tubes, heated by the exhaust from the engine. Additional air is drawn into the vaporizer and mixed with the heated mixture before it enters the engine.
Referring now to all the views, the vaporizer consists `of an exhaust inlet part 4, an
exhaust outlet part 5 and two air inlet parts 6 and 7. The parts 4 and 5 are similar but turned in opposite directions and so are the parts 6 and 7. All these parts are similar in shape and size to the boss on the engine and are bolted between the carburetor and the engine by means of cap screws passing through the holes 8 and 9. These holes extend through all four parts and as they align with the holes in the carburetor and engine, no drilling or tapping in either of these is necessary.
The exhaust inlet part 4 and the exhaust outlet part 5 are each provided with internallythreaded branches 10, 11 and 12, 13 respectively. On the sides facing each other, these parts are also'provided with circular recesses, so that when the two parts are assembled a chamber 14 is formed. The inlets 10 and 11 communicate with this chamber through the openings 15 and 16, while the outlets 12 and 13 communicate with the chamber through the openings 17 and 18. Inside the chamber 14 a plurality of tubes 19 are' placed; these tubes are riveted between the parts 4 and 5 and are open atboth ends, as plainly shown on Figs. 2 and 3. However, only a few of these tubes are shown in Figs. 2 and 3.
The air inlet part 7 has a conical opening, the large end of which is placed adjacent to the exhaust inlet part 4. An air distribution chamber 21 is formed in the conical opening 2O by turning a4 recess in this opening and covering it with a conical washer 22. This washer is so constructed that it forms part of the opening 2O and is perforated by a pluralityof small, air holes 23. An internally threaded air inlet 24 is: provided on the periphery of part 7 and an air passage 25 connects this inlet with the air distribution chamber 21. A wire mesh screen 26 is also placed in the opening 20. The air inlet part 6 is likewise provided with a conical opening 27, an air distribution chamber 23, a washer 29 having perforations 30, an internally threaded air inlet 31, an air passage 32 and a wire mesh screen 33. Y
The conical openings 20 and 27 are so pro portioned that their small ends correspond in size to the openings in the carburetor and ing through the branches enters the chamberY through the openinOs and 16 and heats the tubes 19. From the chamber 14- the exhaustis expelled through the openings 17,
The mixture of gasoline and air, after leaving the carburetor, flows through the opening 2O and is mixed with additional air drawnthrough the air inlet 24, airl passage 25, air distribution chamber 21 and perforations 2?). The wire mesh screen interposed in the opening causes the mixture and added air 'to thoroughly mix. The fuel now flows through `the tubes 19 Where. it is heated to complete vapori/sation and finally through the opening 27 into the engine. In passing through the opening 27 air, When needed, is drawn through the perforations 30.
lt Will be noted that the air drawn from the chamber 21 is heated'by passing through the tubes 19 with the rest of the fuel, While the air drawn 'from the chamber 28 does not pass through these tubes, thus it is possible to supply either hotor cold air or both. Manually operated air vvalves may be attached in either one or both of the air in-V an inner part having a chamber with one or more inlets and outlets through which the exhaust from the engine flows; a plurality of tubes placed in said chamber and heated by f the exhaust; a fuel inletpart having aA conical ope-ning communicating with the said tubes; an air inlet in said fuel inlet part; a screen interposed in said conical opening; a fuel outlet art for Ouidino" the va oorized fuel P e: n
into the engine; an air inlet in said fuel outlet part; and means for attaching the va porizer.
2. In a vaporizer of the class described; an inner ypart having a chamber with one or more inlets and outlets through which the exhaust from the engine iioivs; a `plurality of tubes placed in said chamber and heated by the exhaust; a fuel inlet having a conical opening communicating With said tubes; a fuel outlet for guiding the va.- porizedfuel into theengine; air inlets in said fuel Vinlet and outlet; means for distribut-ingthe air from said -air inlets evenly; screens interposed in the fuel inlet and outlet for mixing the added air with the fuel; and. `means for attaching the vaporizer,
