Serial No. 613,084.

To all whom it may concern:

Be it known that I, SAMUEL N. NORTH,

citizen of the United States, residing at.

Rising Sun, in the county of Ohio and State of Indiana, have invented certain new and useful Improvements in Gas-Generators, of

which the following is a specification.

My invention relates to generators for gas machines designed for generating gas from gasolene, alcohol and other liquid fying the liquid hydrocarbon by more completely superheating the gas generated therein and so constructed that the generated gas shall be submitted to the action of the burner a number of times before passing out through the delivery duct.

A further object is the provision of a generator of this character wherein the gasolene containing portion of the generator shall be separated from the superheating portion by an air space, thus preventing the absorption of the heat from the gas by the liquid hydrocarbon contained in the first named portion of the generator.

A further object is the provision of means whereby the gas generated in starting the machine may pass directly from the superheating chamber to the delivery pipe and not act to force any liquid gasolene or other hydrocarbon out of the delivery pipe.

While I have shown my generator as being applied to a particular form of gas machine, I Wish it understood that I have shown this form as an illustration of the application of my generator and do not wish to be limited to this use.

My invention is illustrated in the accompanying drawings wherein:

Figure 1 is a side elevation of a gas machine with my improved generator applied thereto, the casing surrounding a portion of the machinery and the generator being shown in sect-ion. Fig. 2 is a longitudinal sect-ion of the generator separated from the rest of the machine, the burner being also shown in section. Fig.3 is a view of the under side of the generator. Fig. 4 is a section on the line 4.'4: of Fig. 2. Fig. 5 is a section on the line 55 of Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

The gas machine with which my generator is particularly adapted to be used is illustrated in Fig. 1. These parts are well known and are in common use and hence they may be briefly described. In this figure, 2 designates a gasolene tank having a filling opening 3 and provided with an air pump 5 with a connecting tube 4. leading to the filling opening and controlled by an air valve lever 6. 7 designates the filling opening escape pipe which. leads to a main escape pipe 8 connected at its upper end to a governor 9. The tank 2 is connected by pipes 10 and 11 to the generator 12. The pipe 11 leads from the bottom or. lowermost portion of the tank 2 while the pipe 10 leads from the uppermost portion of the tank or reservoir. Surrounding the generator 12 is the burner 13 of any suitable construction and shown as an annular chamber provided with outlet or burner governor valve stem 18. Leading from the generator 12 is a delivery pipe which delivers vapor to the mixing tube 19. 20 designates the body ofan air inducting device and 21 the cover thereof. The gas delivery duct 22 leading from the generator discharges the gas immediately below the air' inducting device and the passage of the gas is regulated by means of a gas delivery valve casing 23 having therein the needle 24 supported by the arm 26 and controlled by the lever 25. Located adjacent to the generating chamber 12 is the initial heating noz- Zle 27 connected to the elbow 28 and having the air valve 29. All these parts are as ordinarily constructed and are inclosed within a casing 30 which entirely surrounds and covers in the governor, the generator, the induction devices and the mixing tube. The needle valve stem, however, extends below the casing so that it may be easily regulated and the casing only incloses one end of the tank and a portion of the escape pipe.

My invention relates specifically to the construction of the generator and a means whereby the gas passing from the liquid containing portion of the generator may be superheated by being passed back and forth through the superheater a number of times before its final discharge, thus causing a more complete gasification of the hydrocarbon and securing a better action of the apparatus.

Referring now to Figs. 2 and 3, which show the detailed construction of the generator, it will be seen that the generator 12 consists of a gasolene chamber 31 designed to contain liquid gasolene and connected near its upper end to the inlet pipe 10 and.

near its lower end to the inlet pipe 11, these pipes leading from the tank or reservoir 2. The reservoir is disposed at an equal height to the generator so that when the tank or reservoir 2 is filled, the liquid gasolene or other hydrocarbon will not flow through the top connection of the generator. Disposed parallel to the liquid containing chamber 31 is a gas chamber 32 which is connected at its upper end to the gasolene chamber 31, and disposed parallel to the gas chamber 32 is a gas chamber 33 which is disposed parallel to the chamber 32 and connected at its'lower end thereto. This chamber 33 only extends part way up the length of the chamber 32 to a point'above the burner 13 and then extends outward and is connected to the gas a delivery pipe 22. Preferably these several chambers are cast in one piece, the chambers 32 and 33 being separated merely by a common wall 34 which does not extend .down to the lower ends of the chambers and the upper portions of the chambers 31 and 32 being always separated by a common wall .35 which does not extend to the lower ends of'the chambers 31 and 32. The lower portions of the chambers 31 and 32 are separated by an air space 36 which extends up to a point above the burner 13. It will be seen that the upper portion of the body of the generator forms a cylinder divided into two chambers by a common partition wall 35. The upper end of the generator is closed by a many sided plug 37 having a screw threaded annular flange 38. Extending across the lower end of the chamber 31 is a wall 40 having therein, as shown in Fig.3, an opening closed .by the hollow screw threaded plug 39. Extending across the cylindrical body whichform's the lower conjoined ends of the'chambers 32 and 33 is a wall. 40 having therein an opening closed by a hollow screw threaded plug 41.

The plug 41 isprovided with a drainage opening 42 closed by ascrew threaded plug pin 43,.and the plug "39 is formed with a drainage opening 42 closed by a screw threaded plug pin 43. The partition wall 34 at a pointy just directly opposite to the delivery pipe 22 is provided with a perforation 44, this perforation acting as a safety opening to permit the initial passage of gas from the upper portion of the generator where the lower portions of the chambers 32 and 33 are filled with liquid gasolene, thus preventing the liquid gasolene so contained from being driven out of the delivery pipe 22 by the pressure of gas behind it. The gasolene chamber is intended to be filled with granular particles such as gravel which may be contained within a pocket or sack of closely woven brass wire. These granular particles are designated 45 and the sack or other holder for the same is 46.

It will be seen from Fig. 1 that the lower end of the generator projects below the casing 30 in such manner that the plug 41 may be easily removed without removing the casing30. This plug is removed when it is desired to clean the generator.

By reference to Fig. 1 it will be seen that the plug pin 43 which closes the drainage opening into the gasolene containing chamber 31 projects through the bottom of the casing 30 and is screw threaded for engagement with a nut 47 whereby the bottom of the sheet metal box or casing 30 may be supported. The lower end of the combined the lower face of the many sided cap or plug 41 and the needle support 26.

I find it unnecessary in practice to extend the gasolene containing chamber 31 through the bottom of the metal casing 30 as there is no chance of carbonization within. this chamber 31. All 'carbonizing will take place in chambers 32 and 33 and by taking out the plugs 39 and 41 and the gas dellvery valve 23, the machine can be cleaned thoroughly and without taking the same from the supporting brackets.

The operation of my invention'is as follows. Liquid gasolene or other hydrocarbon and like products flow in at the pipe 11 from the tank and fills the'gasolene containing chamber up to a point just below the inlet pipe 10, this being the height of the gasolene in the tank. In order to start the apparatus, a flame is initially projected against the wall of the generator by means of the initial heating nozzle 27; 'Normally,

however, this nozzle is cut off and heat is secured through the burner 13. The gasolene contained within the compartment or chamber 31 is volatilized and the vapor from this gasolene passes upward to the upper end of the compartment 31 and into the upper end of the compartment or chamber 32, downwhich it flows in the direction of the arrows in Fig. 2. The vaporized hydrocarbon passes downward the whole length of the chamber 32 and in so doing is carried downward through the 'center of the surrounding burner 13 so that it is thoroughly heated. At the lower end of the chamber 32 the vaporized gasolene passes into the upwardly extending chamber 33 and is again passed through the center of the burner 13 and is directly subjected to the heat from the burner. It then passes off through the pipe 22 over the top of the burner and is therefore even more fully subjected to the heat of the burner.

In the ordinary form of generator of this type of machine, the gasolene is volatilized in one compartment or chamber of the genorator, then passes into the other compartment, passes half way down therein and then passes directly out through the delivery pipe. As a consequence the gas is not sufficiently heated as it is not once passed entirely through the burner, to say nothing of passing through the burner a number of times. It often occurs that after the machine has been tested at the factory the lower ends of the chambers 32 and 33 contain liquid gasolene. It will be obvious that any gasolene contained in the lower ends of the chambers 32 and 33 will prevent the passage of gas from the chamber 32 into the chamber 33, and under these conditions if vaporization was started, the pressure of the gas in the upper portion of the chamber 32 would act to force this liquid gasolene out through the delivery pipe. In order to prevent this, I have provided the perforation 414 so that the gas may pass directly from the upper portion of the chamber 32 through said perforation and through the delivery pipe. This passage of gas will continue until the gasolene in the lower portion of the chambers 32 and 33 has become vaporized, whereupon the gas will be free to pass downward through the entire length of the chamber 32 and into the lower end of the chamber 33 and so out, the perforation 44 being so small, relatively speaking, as to permit the escape of only a very small portion of the gas directly to the delivery pipe.

By providing the air space 36 which separ'ates the two legs of the generator, I prevent the liquid gasolene contained in the chamber 31 acting to absorb the heat of the gas in the chamber 32. I have found in practice that my generator is economical and thoroughly effective and that the superheated gas is much superior to gas which passes almost directly from the gasolene chamber to the outlet pipe without being superheated.
