This invention relates to that classification of structures grouped under so-called automotive appliances and accessories, and it has more specific reference to what is unitarily referred to as 5 a fuel-oil vaporizing attachment.
The primary purpose of the invention is to provide a novel fuel saving device susceptible of being used in conjunction with a more-or-less standardizedcarburetor, intake manifold assembly on present day internal combustion engines.
Needless to say, I am aware that fuel-oil conversion burners and Vaporizers fonmotors and the like are not broadlynewa It follows, therefore, that my primary purpose and aim. is to provide what is believed to be an improved and ingenious adaptation characterized .by simple and economical arrangements having gasolene priming means and complemental fuel-oil conditioning and handling means distinguished essentially by a well balancedoand appropriate continuity .of
parts embodying/an efficient vaporizer and a duplex or two-way conduit structure suitably coaoting therewith.
Other features and advantages will be more readily apparent from the following description and the accompanying illustrative drawings.
In the drawings:-
Figure 1 is a view partly in section, and partly in elevation showing carburetor, exhaust manifold and fuel-oil conversion attachment mechanically correlated with these parts.
Figure 2 is a vertical sectional View taken at right-angles to Figure 1.
Figure 3 is a horizontal section on the line 3-3 of Figure 1.
Figure 4 is a detail or plan view of the exhaust manifold insert or vaporizer portion of my invention.
Referring first to Figure 2 it will be observed that the motor or engine, which is conventional,
is indicated by the numeral 5, this having attached thereto a regulation exhaust manifold 6. The carburetor, which is expressly constructed to handle an appropriate grade inexpensive fuel-oil, is indicated by the numeral 1. The intake manifold is denoted at 8. Incidentally, I have shown merely a portion of the depending branch of the intake manifold for clearness of illustration.
Starting at the top of the structure, attention is invited to the numeral ,9 which designates what may be conveniently called a vaporizing unit, this being in the nature of an insert susceptible of being built in or otherwise fitted in the exhaust manifold as shown. This unit comprises a simple casting having a longitudinal body portion I 0 and intake and outlet nipples or branches II and I2. These are fitted into openings in one wall of the exhaust manifold and also into, appropriate openings in the adapter plate l3 The. plate may be of any appropriate design and is preferably pro 5 vided with a series of radiating fins l4.
Connected by way of an attaching flange l5 to the adapter plate is a two-way union or fitting l6. Thisfitting includes, an attaching neck I! as shown in Figure 2 depending belowaconcentric 10 inner attaching neck 18. The fuel-oil supply. or inlet duct in this casting, which is suitably shaped, is indicatedat ,l9,and registers with the neck l8 and the intake nipple II on the intake 9. The discharge passage for the vaporized fuel-oil 15 gas is designatedby the numeral 20, and registers with the outlet nipple I2 and conduit ll. 6
Attention comes at this time to the. numeral 2| which designates what may be conveniently called an-elbow in that it is substantially L-shaped in 20 configuration and in the form of a comparatively heavyv metal one-piece casting of a multiple purpose type. It includes .-a substantially annular horizontal branch ,2.2. provided with a partition 23 which partition merges into and is formed 25 integral with a supporting collar 24 arranged in spaced concentric relation within the limits of the laterally projecting tubular branch 25. These features 23, 24 and 25 cooperate in defining proper jointing means between the parts as well as a 30 gasolene receiving and priming well 26. Incidentally, gasolene is supplied by appropriate valved priming pipe means and enters or communicates with the well 26 by way of the pipe or primer connection 21.
Located between these upper and lower fittings or castings l6 and 2| are inner and outer pipes 28 and 29. The inner pipe which is smaller in diameter than the outer pipe and concentrically spaced therefrom has its lower end attached to 40 the internal collar24 and its upper end to the internal accommodation and supporting neck I8. The outer pipe 29 has corresponding connection with the upper neck i1 and the correspondingly shaped branch 25 of the lower elbow or casting 2 l 5 This spacing of pipes defines a passage 30 therebetween which permits downward flow of the vaporized gases from the vaporizing unit 9 to the intake manifold 8.
In operation it is understood that the carbure- 50 tor 1 contains the fuel-oil and is supplied from an appropriate tank or reservoir. (Not shown.) Initially, the gasoline priming line, which feeds through the connection 21 is opened to deliver a predetermined quantity of gasolene into the prim- 55 ing well or pan 26. Then by starting the motor this gasolene is initially utilized to create the requisite suction to cause the fuel-oil in the carburetor to function. In fact when the suction is suflicient, the fuel-oil is sucked up from the carburetor I through the inner pipe 28 where it is delivered by way of passage 19 into the intake nipple ll of the vaporizer. The vaporizer being located in the exhaust manifold converts the fuel-oil into vapor gases, the vapor gases then being circulated and sucked down through the passage 30. Going through this passage they pass on into the intake manifold 8 by Way of the duct comprising the passage 30 and its communicating lower end portion with the so-called well 26. Manifestly, when once the vaporization action is effected the gasolene line is turned off and the motor continues to run on the fuel generated through the instrumentality of this vaporizing attachment.
It is thought that persons skilled in the art to which the invention relates will be. able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.
Minor changes in shape, size, and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.
Having thus described the invention, what I claim is:

As a component part of anattachment of the class described, an adapter plate designed for connection with an exhaust manifold, said plate being provided with radiating fins and apertures, a vaporizing unit adapted for insertion in an exhaust manifold comprising a longitudinal elongated tubular body provided with intake and return branches having laterally directed nipples located in the apertures in said adapter plate.
2. As a component part of an attachment of the class described, an adapter plate designed for connection with an exhaust manifold, said plate being provided with radiating fins and apertures, a vaporizing unit adapted for insertion in an exhaust manifold comprising a longitudinally elongated tubular body provided with intake and return branches having laterally directed nipples located in the apertures in said adapter plate, together with an adapter casting having a flange attached to said plate, said casting including supply and return ducts and inner and outer pipe accommodation and attaching necks with which the ducts are respectively registrable.
3. As a new article of manufacture and as a component part of an attachment of the class described, an adapter casting designed for connection to an exhaust manifold in cooperation with a vaporizing unit comprising an attaching flange, a body having separate passages, said body being further provided with a laterally directed end portion formed with inner and outer concentric attaching necks with which the passages have individual communication.
