TANK CARBURETOB.

Application led May 21,

To all 'whom it may concern:

Be it known that I, HARRY DAL'roN, Sr., a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in a Tank Carburetor, of which the following is a specification.

My invention relates to new and .useful l0 improvements in a tank carburetor, and

method of producing carbureted fuel for internal combustion engines, and has for its object to provide for carbureting a volatile fluid contained within a suitable storage tank making it unnecessary to use separate storage tanks and carburetors. Y

A further object of the invention is to vaporize the volatile iiuid in such manner as to prevent undue separation of the lighter elements from the heavier elements thereof by utilizing a series of wicks for elevating the fluid and exposing the same upon fibrous air swept surfaces.

A further object of the invention is to provide means for properly direct-ing the air drawn to and from the tank by the action of the engine so that said air in its passage through the tank will sweep all of the liquid exposing surfaces uniformly.

A further object of the invention' is to provide for heating the airain its passage to the tank and also to heat the air admitted to the fuel supply pipe prior to entering the manifold of the engine and to give a swirl- 36 ing motion to said air.

A still further object of the invention is to provide for carrying out the above named ob ects in a simpleA and effective manner.

ith these and other objects in view, this cc invention consists in the details of construction and combination-of elements herein-v after set forth and then specifically designated by the claims.

In order that those skilled in the art to 4E which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application, in

In carrying out my invention as here embodied, l represents the supply tank which may be of any desired shape or size and is intended to carry a supply of'volatile liquid such as gasolene or kerosene which may be introduced thereto through the hopper or funnel 2- so ositioned as to prevent the over illing oi) the tank. Within the tank and spaced at a proper distance from the top thereof are two shelves 3 one vat each end of the tank. These shelves act as supports for channelways or wick holders.

4; represent the wick holders which are in the form of channelways, each consisting of a top section 5, two sides 6 bent at right angles to the top section and end langes 7 in which latter are formed a number of holes 8. f

9 represent'the wicks which are suspended*v from rods 10, the ends of the latter being secured in the holes 9, said rods acting as spacers for the wicks at the top thereof while a series of strips 11 of wood or -other suitable material serve as spacers for said wicks at a certain distance below. These of the i 1 fei- |veye'd to the manifold 18 of the engine 19,

lrand in this pipe at any suitable point is strips 11 are secured in place by the wires 12 which pass through the wicks and strips, as shown in Fi 7, and extend crosswise the entire width o the wicks. Thus it will be seen that each holder carrying a series of wicks may be placed in the tank, the ends thereof resting upon the shelves 3, suspending the lower portion of the wicks within the tankbelow the Shel-ves, and when the several holders are so placed the strips 11 will act as a ballie dividing the tank horizontally into two compartments A and B, the former for containing the volatile liquid and the latter for the formation of the carbureted fuel mixture. This baffle also serves to prevent the sloshing of the volatile liquid into the compartment B when the device is used on 'automobiles While there may be any desired number of wick holders I have here shown but three, each of which has its sides cutaway to form air passages 13 and 14, said cutaway portions being at opposite ends of the holder and on o posite sides thereof, thus when these holdhrs are properly placed within the compartment B a to and fro passage is provided for the ow of the air `through said compartment.

15 represents the inlet for air to the compartment B which is so placed relative to the wick holders when the latter are positioned in the tank that the incoming air will enter one end of one of the channelways or Wick holders and flowing therethrough pass to the next channelway through the cutaway portion 13 of one channelway and the cutaway portion 14 of the adjacent channelway, then backward through this adjacent channelway and through the opposite cutaway portions to the next adjacent channelway and again forward through this last named channelway to the outlet 16, as indicated by the arrows in Fig. 5. As-this air passes through the channelways it will impinge upon and sweep the surfaces of the upper portions of the wicks 9 which are so spaced in saidchannelways as to cause said air to pass therebetween, thus evaporating the volatile liquid exposed upon said surfaces and thereby becoming thoroughly saturated with the vaporand forming the carbureted fuel mixture for combustion in the engine.

The outlet 16 leads into the fuel supply pipe 17 by which the gasolene fuel is conlocated athrottle valve 20, which may be of any suitable construction, herelshown, of the butterfly type. Since it is highly important that the air entering the compartment B shall be in condition to rapidly evaporate and absorb the volatile liquid from the ex osecl surfaces of the wicks, I connect the inlet 15 with an intake pipe 21 a portion of which is coiled about the engine aaeaoie exhaust 22 as shown at 23, so that. the lincoming air will be heated. The carbureting of the inflowin to produce a hig ly enriched fuel, and while this is advantageous, it is desirable in the operation of internal conbustion engines, especially' for automobile vehicles to be able to vary the richness of said fuel in its assage to the engine, therefore I provi e a secondary intake 24 leading into the intake 17 between the throttle valve and the manifold at an angle and in this secondary intake is located a control valve 25 by which the amount of air admitted through this secondary intake may be varied, said valve may be operated by any suitable rod or other mechanism terminating in easy reach of the engine driver. In order that the air passing to the intake 17 through the secondary intake 24 may be heated to prevent the chilling of the gaseous fluid I connect the pipe 26 with said secondary intake and so dispose va portion thereof relative to the exhaust or some other heated portion of the engine as to heat the air passing therethrough, the arrangement here shown being the coil 27 placed around the exhaust 22. Y

l I have found in practice that better results are obtained when the air passing through the intake 24 is given a swirling motion and I therefore position a spiral 28 in this intake so that as the air passes therethrough it will be given a s iral motion and thus when commingling wit the fluid pass-` ing to the engine through the intake 17 'will tend more thoroughly to mix therewith.

In order that the air flowing to the tank throu h the intake ipe 21 may be controlle I locate a va ve 30 of any suitable design here shown as a butterflyvalve in said pipe and carry a rod or connection 3l .therefrom within easy reach of the engine attendant and as the closing or partly closin of this valve will tend to create a partiaI vacuum within the tank, I provide a relief valve 32 of any suitable construction which will prevent'the formation of-an. undiie degree of vacuum in the tank.

air in this system tends By the arangement of ,wicks as herein described it has been found that the raising of the volatile liquid from the com artment A to the compartment B has litt e or no tendency to separate the li hter from the heavier portionsv of said Hui and therefore the entire contents of the tank will be raised and vaporized without leaving behind the heavier component parts of said uid, and by this system the numerous disadvantages attendant upon the use of the separate carbureter are entirely overcom While I have here shown one embodiment of my invention it is obvious that it may be embodied in various forms and the construction of the `several vparts thereof may be widely varied without departing from the spirit of my invention and Ithereore do not wish to be understood as limitin myself to the exact details of construction iere shown and described as these may be varied within the limits of the appended claims Havin thus fully described my invention, what I c aim as new and useful is 1. In a device of the character described, a supply tank, a'plurality of channels positioned in the upper portion of the tank, al series ofwicks suspended from the channels, said wicks bemg spaced apart, a baille through which said wicks pass, said baille dividing the tank into an upper and lower compartment, and means for causing a current of air to flow through the channels whereby the surfaces of the wicks above the baille will be swept by said air.

2. In a device of the character described, a supply tank, two shelves secured within said tank, wick holders in the form of channelways supported by said shelves, a series of wicks having their upperportions secured within-each of said holders, said wicks projecting downward to the bottom of the tank and bein .spaced apart, a series of strips interpose between the wicks forming a baille to divide the tank linto an upper and lower compartment, and means for causing a current of air to flow through the channelways between the upper portion of the wicks. s,

3. In combinationwith a supply tank for internal combusition engines, a series of channelways located within the upper portion of the tank and placed side by side,

cutaway portions inthe side walls of the channelways for providing air passages from one channelway to another, a series of rods secured in cachtof the channelways,

series of wicks suspended from said rods, v

spacing stripssecure between the wicks in such manner as to form abaille for dividing the tank into an uppery and lower compartment, and means for causing, air to' lw throuv h the channelways.

4. In a car uretor, the combination with a supply tank having an inlet and an outlet, of a plurality of channelways located in parallelism within the upper portion o the tank and in inverted positions, the side walls of saidfchannelways having cutaway portions adjacent opposite ends, the cutaway portions `of one channelway registering with 'those in adjacent channelways to provide a circuitouspassageway and a series of wicks mounted within each of the kchannelways and hanging ,below the same-.

5. In. a device of the character stated, the combination of a supply tank, two shelves within the tank at opposite ends thereof, a plurality of inverted `channel wick holders closed at their ends and supported by said shelves, each of .said channel ways communicating with adjacent channelways at opposite ends to form a circuitous air passageway above the fuel level of the tank, wicks suspended within said channelwa s and hanging below the fuel level and v strlps located between the wicks and to which the latter are secured said strips being located adjacent the c anelways and dividing the interior of the tank into two compartments.
