CARBURETER.

Specication of Letters Patent.

Application filed May 29, 191,4. Serial No. 841,820.

To all 'whom it may concern.'

Be it known that I, WILLIAM J. OMER, a citizen of the United States, and a resident of Thomas, in the county of Custer and State of Oklahoma, have invented a new and useful Improvement in Carbureters,.of which the following is a specification.

My invention isan improvement in carbureters, and has for its object. to provide a device of the character specified, adapted for use with internal combustion engines of every character, wherein mechanism is -provided for thoroughly volatilizing gasolene or other liquid fuel, and for mixing the volatilized fuel with air to provide for perfeet combustion of the fuel.

The -primary object of the invention is to provide mechanism for controlling the mixture without the use of the'usual float valves, and without the necessity for adjusting the relative proportions of fuel and air in accordance with conditions of load and road.

A further object is to provide mechanism in connection with the carbureter forheating the-mixture, before it passes to the combustion chamber of the engine.

In 'the drawingtsz-Figure 1` is an enlarged section taken on the line 1-1 of Fig. 3, Fig. 2 is a section on the line 2 -2 of Fig. 1, Fig. 3 is a top plan view with parts broken away, and Fig. 4 is a partial side view of a modified construction.

The present embodiment of the invention is shown in connection with the fuel tank 1, of an internal combustion engine,'the tank being of any usual or desired form, and

receptacle as shown. A tubular casing or pipe 2 is arranged at the center of the tank,

extending through'the top or cover thereof to a point'near the bottom of the tank. At its upper end the pipe 2 is integrally connected to the cover by means of a ring 3, which extends above and below the top. Above the top the ring is reduced annularly to form a shoulder 4 near the vupper end thereof and above the shoulder the ring is screw threaded to receive a cover. The cover comprises a concave-convex top 5 arranged with its convex surface upward, and an internally threaded ring 6 which engages the threel` led portion at the top of the pipe 2, and the top 5-is connected to thevring by arms 7, the said arms being arranged at angular intervals of 90 with respect to each other. The cover is square as shown in Fig. 8, and the arms 7 are at the corners. The arrangement of the arms 7 provides for four openings for placing the interior of the cover in communication with the atmosphere. The .openings are normally'closed by means of gates or valves 8, of frustopyramidical form, each valve or gate being hinged to the cover as indicated at 9, at the outer edge of the gate orvalve. The pipe 2 lis provided with a number of annular series of openings 11 near its upper end, and commencing just below the ring. tubular structure is arranged within the tank at the top thereof, the said structure l consisting of a series ofstraight sections 12, and elbows 13 and 14 lfor connecting the ends of the straight sections with. each other. The elbows 13 and 14. are merely tubular, but the sections 12 may be described as split tubes and they are arranged with the split on the under side thereof. Each of the said sections is provided at each side of the split with a depending llangc 15, and the flanges 15 of each section are'arranged in spaced and parallel relation. A sheet of wicking is supported by each of the sections 1'2 of the tubular structure, the said sheet being doubled upon itself to form folds 16 and 16a. The yjunction between the folds of each sheet is held within the adjacent section 12, and mechanism is arranged within the fold for holding the said fold or junction inclose contact with the interior of the section. Thisv mechanism in the present instance, is a tubular casing 17 of gauze or the like,

the wicking .when the wicking is in contact with the interior of the section. The folds 16 and 16a depend through the' split ofthe section, and between the flanges 15 of the section to a point at or near the bottom of the tank.

The sections12 are held in position near the top of the tank and above the `level of the liquid therein by means of transverse partitions 19', and each of the said partitions 19 is provided with an opening 20 at its'bottom for placing the entire tank in communication. The lower edges of the flanges 15 are bent outwardly as shown at 21,4 and the said lower edges rest upon the upper edges of the partitions 19.

Detecting plates 22, 23 and 24 are arranged between the flanges 15 of the adja- Patented J uly 28, 1914.

of such cross section thatl it will fit within cent section 12, the seitig/plates differing only in width. The plats"22 are arranged between the side wallpfbhe tank and the adjacent lange of the-.tadjacent section 12. 5 The plate 24 isv arranged at the center of the tank between the two central sections, and the plates 23 are arranged between the lateral section at each side of the tube 2. Each of the plate's'22,` 23 and 24 is bent at its cen? rivets 27, arranged below lthe rivets 26.'

\ Each of the plates 22, 23 and 24 is provided with a longitudinal series of openings 28 at l its center, and the .plate 24 has an opening through which the pipe 2cpasses. The folds of wicking extend only to the ends ofthe .l sections 12, 'but the plates 22, 23 and 24 extend from one end of the casing to the other,

' and are continued along' the ends of the casingas indicated at 29. The plates 22-23- 30 24 and 29 are in fact an integral structure which divide the tank into upper and lower compartments, the`v liquid fuel being below the said partition, and the openings 28 provide a communication between the compartments. lIt will be noted from an inspection of Figs. 1 and 3 that the outermost section 12 is extended at one end through the adjacent end ofthe tank, as indicated at 30, and that the outermost section at the opposite end of the tank extends only about half the length of the tank. An elbow 31 connects the free end of the section with a vertical pipe 32, which passes downwardly from the elbow through the bottom of the tank, being .reinforced-at the bottom 'with a ring 33. An elbow 34 is connected with the lowerl end of the pipe 32 below the ring, and a section 35 of pipe is connected with the other end of the elbow. The pipe 35 is adapted for connection with the manifold of the engine, either directly or indirectly as conditio-nsmay y require. The usual throttle valve 36 is ar ranged in the section 35 of pipe, thevalve being secured to the shaft or rod37, journaled -transversely of the pipe and provided at its outer end with the arm 38 for manipulatingl the shaft. Screens 39- and 40 are arranged within the pipe 25 at spaced intervals, for

60 preventingdamage from backfiring. Should the flame from back ring pass the throttle valve, it would be checked by the screen.

A valve 41 is arranged within the extension 30, the said valve cooperating with the seat 42, and the valve is provided with fa ,monaci stern 43, passingvthrough a spider 44 inthe pipe for guiding the stem. A coil spring 45 encircles the stem between the spider and a stop 46 threaded on to the rod, the spring acting normally to hold the valve closed. The stop in the present instance is a nut and washer, and it 'will be evident that the tension of the .spring may be varied by moving the nut. One end of the spring is connected to the spider and the other to the stop. In case of back firing the valve Vwill relieve any excess oressure'in the tubular structure, and

the valve may also be used for admitting air when necessary. The spring. 45 may be arranged to hold the/valve partially open 1n order to admit air when conditions require more air than enters by way of the valves 8 and thev openings/,11 of the pipe 2.

The device is also arranged in such manner that itmay be utilized'as a self starter for the engine. For this purpose a nip le or tube 47 is arranged transversely of t e top and extending through the same, and the outer end of the-tube is adapted for connection with a flexible pipe 48, the other end of which is connected with a suitable compressing device, as for instance, any means for compressing air, such as a bulb or pump. When it is desired to start the engine in this manner air under pressure is forced through the tube 47, and this air under pressure will enter the openings 18, and will pass through f the tubular structure and the pipes 32 and 35 tothe engine.

[Mechanism may also be arranged within the tank 1 for heating the tubular structure, consisting of the pipes 12 and the elbows 13 and 14. This mechanism is shown in. Fig. 4, wherein resistance wires 49 and 50 are arranged on opposite sides of the Vopenings -18a in the sections 12a of the tubularI structure. These sections have the depending 'flanges 15, corresponding to the flanges 15, and the folds 51 ofwickingare connected therewith and'with the sections in the same manner as above described. The resistance wires 49 and 50 are connected with a suitable source of electrical energy capable of heating the wires. It will be obvious that when so con,- nected the pipeswill be heated and the mixture passing through the pipes will be heated during its passage through the pipes. It

will be understood that any form of heater may be used in -this connection.

`The operation of the improved carbureter is as follows:-The fuel tank is filled with liquid fuel to about-the level shown, and in a very short time the depending folds 16 and 16 Vwill become saturated with the fueland by capillary attraction the fuel will pass into the tubular casing. The wickA 'acts in the same manner as the wick of an oil lamp and it will be evident that so long'as there is 'any fuel in the tank itv will be drawn into vthe tube. Nfter the wicking s been thormentari oughly saturated in this manner, whenever'l the engine is started in the usual manner air will be drawn through the openings in the cover 5, lifting the valves 8 and passing into the tube 2 and entering the body 0f the tank through the openings 11. From the interior of the tank the air will be drawn into the tubular structure through the openings 18, andv will vaporize the fuel held by the wicking. As the air passes through the openings 18 and through the wicking to the interior of the tubular structure it will vaporize the fuel held` by the wicking and will carry the same through the tubular structure to the engine. Wlienthe heating device' is used in connection with the tubing the air will be heated as it passes to the engine. In

case a mixture of less richness were required the valve 41 would be open to admit a greater quantity ofair. lVhen it is desired to fill the tank or to renew the fuel the `cover is turned off from the upper end of the pipe 2, and the fuel is poured through the pipe 2 into the tank. The plates 22- 23-24 are baffle plates to prevent the fuel splashing into the upper part of the tank, and toprevent any non-volatilized fuel passing through the engine. Any fuel that would pass above the -plates will be returned to the body of the tank through the openings Q8.
