JAMES-CLARENCE ROGERS, or GRAYSON, GEORGIA.

GARBU ETER To atom/m it may concern: p -Be it'known that-I, JAMES C. Rooms,- a citizen of the United States, residingat Grayson, in" the county of Gwinnett and 5 State of Georgia, have inventeda new and is a Specification.

Thisinvention relates to improvements in carburetors for explosive engines.

An object of. the present invention is to provide a carbureter particularly adapted to vaporize-the'heavier and less volatile oils, su'ch'as kerosene A,-,iurtlier jbbjeet of the invention is to provide 'a 'carbureter with 4 automatiecom trolling means whereby the amount ofifuel useful Carbureter of which the following delivered to the mixing chamber will be pro-' portionalto the air entering therein, whereby a proper'mixtureof'thefltwo ingredients yo for the format-ion'of, a combustible gaswill at,alltimes'be had;

With the foregoinghndiother objects in view which will appean-as the'descriptionproceeds, the invention residsijn' thefcom bination and arrangement of parts and in the details' of -'eonstr ucti0nlii'einafter 'described. and claimed, it being *understood that-changes in the precise e mbodiinent of the invention herein disclosed can-be made within the scope of what is claimed without fication and forming a part thereof, the preferable form of m yinvention is illustrated, in which'' .Figure 1 is a vertical sectional :view of a carbureter embodying the features-"of my in ventiorx; Fig'. 2 is a cross sectional view thereof taken on theline 22.'v

arm 13, which latter has the aperture 14 extending through the outer extremity thereof and may be connected to the controlling levers sothat this valve may also be held in adjusted positions: i The liquid fuel chamber 6 is provided with the fuel inlet pipe 15 with a suitable valve 16 controlling the saine,.the upper extremity of the valve stem being pivotally 3 connected to a buoyant float-17 so, that the liquid fuel will be maintained at a constant I p An outlet. pipe 18 communicates with the lower portion of Y the fuel containing chamber 6 and terminates in the-mixing chamber into Which it is adapted to supply 'theiliquid fuel. 'A 1 plun er valve 19 is adapted to control the supp y of liquid fuel passing through the fuel supply pipe 18 into the mixing chamber and is pivotally secured to the lever 20 so that :1 raising of the outer extremity of the lever 2O will result in the opening of the valve and allowing thepassage of the liquid fuel into the upper portion of the mixing chamber 4. The fuel containing chamber. 6 is rigidly secured to' the bracket? by set screws 21 or other equivalent means and which also hold the'bracket to the mixingv chamber.

Extending across the air inlet pipe 3 is a supporting. bracket 22 which provides a hearing for a shaft 23 which extends longitudinally of the mixing chamber, extends through the base thereof as'at 24: and terminates in a thrust bearing 25 which is supported by a sub-frame 26. The shaft 523; is provided with an outstanding blade 27 secured thereto, and which as will be apparent from a referenceto Fig. 2, is in the nature of broad flat surfaces, preferably formed of wire, the mesheof which is'sutliciently fine so'as to break the liquid-fuel as it drops from the pipe 18 into an infinite number of fine particles of vapor like consistency.- A propeller) 28sis rigidly secured to'tlie upper extremity of th'e shaft 23 and is positioned Within air. inletpipe 3 so ,as to be rotated by the air as it passes therethrough for the rotation of the wire blade 2' 7. v v

The sub-frame 26 whereb the thrust bearing 25 is siipported comprises the arm 29'secu'red to the outlet delivery pipe;5 as at 30 and also secured to the mixing chamber 4 as'at 31, Tlie sub-frame extendsfor somejm little distance below=the lower extremity ,of,

,the mixing chamber-and outlet pipe 5 and i sub-frame and extends therebeyond, terminating in a handle or manually engageable portion 39 whereby the governor and parts connected thereto may be raised to produce a result similar to the raising of the governor'balls by an excessive rotation of the shaft 23.

TllQIlQVOI 37 which also engages the loweraifiifintion of the collar 34 is pivotally mounted upon the upstanding column 32 intermediate its ends so that a downward motion of the one extremity of the lever will result in the corresponding upward motion of the opposite end thereof. The free end of the lever 37 is pivotally connected to a link 40, the upper extremity of which is pivotally secured to the lever 20 of the valve 19. Thus as the governor balls are driven outwardly by centrifugal force during the excessive rotation of the shaft I 23, the one extremity of the lever 37 will be drawn upwardly and the opposite end and to which the link 40 is pivotally secured will be drawn downwardly resulting in the plunger 19 being moved up toward its valve seat-for a cutting oii of the supply of fuel through-the full supply 18.

From the foregoing it will be a parent that the fuel entering the mixing chamber is controlled by the position of the governor balls or may also be manually controlled by the-lever 39.

Thus'with the improved form of carbureter as herein described, the liquid fuel as it passes into .the mixing chamber from the pipe 18 will encounter a rapidly rotating blade rotating about an axis parallel to the natural fall of the liquid 30 as to intercept the path thereof and the blade being formed of a wire of somewhat fine mesh will break the fuel into 'fiue particles of spray like form andvthus provide for the eiiicient and rapid evaporation or volatilizationof the same. The rotation of the blade 27 is accomplished by the propeller 28 and is thus proportional to the a'mount of air passing through the pipe 3. Thus it will be apparent that the greater the amount of air passing through the pipes, the greater will be the speed at which the fan blade 27 is rotated so as to insure the proper division and breaking up of the fuel. Also it will be noted that the amount of fuelentering the mixing chamber will be proportional to the speed of rotation of the shaft 23 which in turn is proportional to the quantity or volume of air passing through the inlet pipe 3 and which will be readily appreciated is a function of the speed of rotation of the engine. shaft 23 and parts secured thereto and which rotate therewith, are preferably formed of light material so that the moments of inertia will be kept as low as consistent with the rigid construction and durability ofthe entire device and, which renders the carbureter here described extremely sensitive to changes in the speed of rotation of the engine and allows for the same to quickly and properly take up the extra load which may be brought to bear upon the engine by in-' creasing the fuel supply necessary therefor.- The sensitiveness of the entire device of extreme importance as, it a1lows .for"z"'fine degree of adjustment to be had. Also at-C tention is called to the fact that with the carbureter as herein described kerosene and other hydrocarbons which are not easily volatilized may be used due to the manner in which the blade 27 will break up the liquid into a spray of vapor-like form.

Having thus. fully describedmy invention, whatrI claim is:

1. In a carbureter, the combination of a Y liquid fuel containing chamber with means disposed therein for maintaining the fuel at a constant level, a mixing chamber incomchamber, said foraminous blade intercepting the path of flow of liquid fuel through said mixing chamber to reduce thesame to. a spray, and a propeller carried by the said shaft disposed within the said air inlet pipe and rotated by the ingression of air taken? with respect to said mixing chamber.

2. In a carb ureter, the combination of a mixing chamber,'an' air inlet and a gaseous j fuel outlet pipe communicating therewith, a liquid fuel containing chamber, a liquid fuel outlet pipe communicating with said fuel containing'chamber and .the upperpor tion of said mixing chambeg a valve d1s-. posed within said pipe controlling the flow of liquid therethrough, a propeller disposed within said air inlet pipe actuated by the passage of air-therethrough, a shaft supporting and actuated by said propeller, a foraminous blade carried by said shaft and rotated thereby, tating to intercept the-path of flow of liquid said for-aminous blade '-ro from said mixing chamber, fuel supply pipe, and nwans swin'ml to Saki shaft and conturn in the presence of two witnesses. nvctedtn the sam l \al c w nl nli ng the 1051- JAMES CLARENCE ROGERS.
