CLARENCE Mv'. KEMP, or BAL-ruitenE,` n

Be it known that I, CLARENCE M. KEMR,` a citizen ofthe United States, residing at Baltimore, inthe State o-f Maryland, have invented new andV useful Improvements -in Carbureters, ofwhich the following is a This invention relates toA an apparatus for carburetingjair; more especiallyl to'that class few buildings'with one of machines'formanufacturing gas toilluminate andfheat' individual building, or a plant `such as houses,

factoriesand the like.

The main object of this invention is to Iso' combine and arrange the several parts thereof that a constant level of the carbureting` fluid'within the container may be attained whether that level be high `or low with respect tothe container;that the air to be 4carbureted `shall enter the fluid in vfinely divided particles and as it emerges therefrom be further divided into'minute or atomic particles (in the mechanical sense), thoroughly intermixed with the gaseous par! ticles of the 'carburetingiuid to form a rich and .so-calledfixed'l gas -which has great heat producing and" illuminating properties.

lith these `and other objects in view the invention consists of the construction, combination and arrangement of parts herein after described and 'claimed'andillustrated in the accompanying drawings, in which* Figure 1 is a vertical sectional view of the lower part of a carbureter onstructecl in accordance with my invention; Fig. 2 is a like view of the upper part of the same; Fig. 3,' a horizontal Sectional view on the line'3.-3l of Fig'l, and Fig. 4, a detail sectional view of the inlet `.valve controlling the admission of the hydrocarbon or carbureting fluid.

In the drawings, the lnumeral 10 indicates a tank or container within which air is carbureted and from the bottom of which a preferably cylindrical chamber 11 extends vertically through and above the tank for a r 'su'i'table distance. A cap plate 12 covers upper end of the chamber and is' attached -thereto `in any desired manner, as by a fianged ring 13. The tank is usuall buried in the ground at any required dept and is connected with the surface ofl the ground by a casin 14 screwed into a flange 15 on the upper ace of the cap plate 12.

Ati the surface of the ground, the casing 14 is provided with a closure 16 of any suitable kind, a screw cap .being shown, as an ex ample, 1n the drawing.

lVithin the tank or' container 10, a-short i distance below the top'and surrounding the chamber 11, is 'an air tight'diaphragm '17 forming with the top o the tank, an air receptacle 18 fed byan air pipe 19. from any source-of pressure. Beneath the'diaphragm 17 and a short distance above the bottom of the tank 1'0`is a' relatively thick horizontal lbody or partit-ion 20 fitting against. the walls of the tank and the cylindrical chamber 11. Through the partition in a vertical direction are formed a number of holes 21 arranged preferably in airing concentric with the chamber 11, see Fig. 3; Atlixed Huid tight to the diaphragm 17`and extending 'downwardly through the 'space between the diaphragm and the partition, are a plurality of small tubes 22 equal in number and arrangement to the holes 21 but `of less diameter and projecting into said holes to the bottoms thereof. Attached to the lower end of 'said small tunes ,22 are caps 23 madeof fine reticulated metal or wire gauze which break up the solid streams of air passing down said tubes, when air is forced into the receptacle 18 thro-ugh'the pipe 19, into fine particlesor globules.y

' Surrounding each small tube 22 from the diaphragm 17 through the hole 2 1 to the perforated vcapl23 is a skirt or covering 24 of some absorbent or capillary material, the use of which will be describedV later. The tank or container 10 is kept filled to a certain height with gasolene or other suitable hydrocarbon, in this instance to the top of the artition 20, by means of a float 25 fastenedp on the lower end Aof a. tubular stem 26 mounted'to slide vertically in guides 27 within the, cylindrical "chamber 11. Supui e stem 26 is a cup sha ed receptacle 28'gcommlllmilclsating with sai tubular stem through w 1c opening leading from the cup 28- is covered with areticulated diaphragmff) to prevent the passage of any foreign matter. into the tubular guide stem which would obstruct the same. I

As previously described, air entering the stem gasolene asses to the bottom yof the tank 10 below t e'partition 20. The

tank or container 10- through the pipe 19 passes down the small tubes 22 and out through the reticulated ca s 23 in minute bubbles into the gasolene fi ing the holes 21 in the partition. The escaping' air rises in the holes and is subjected to further division as it passes through the gasolene soaked skirts'24 surrounding the small tubes and filling the holes 21. Durin the upward movement of the automatical y divided air it combines with the volatile elements of the gasolene and enters the space 30 in the tank or container 10 between the diaphragm 17 and the partition 20, as a combustible gas rich in hydrocarbons. The gas flowsrom the space 30 through openings 31 l1n the walls of the chamber 11 into said chami ber and from thence by way of the pipe 32 to the place of consumption.

The volatilization of the gasolene gradually reduces the quantity thereof in the tank andthe normal level falls in said tank and the chamber 11 which communicate through openings 33 at the bottom of said chamber. The float 25 necessarily follows the movement of the gasolenc and opens the gasolene inlet valve 1n the manner now to 'be described.

Within the casing 14 is a vertical tube 34, its upperend terminating a short distance below the top of the casingand its lower end extending through the cover plate ,12 into the chamber 11 and near the bottom of the cup shaped receptacle 28. The tube 34 is screwed into the cover plate 12, and may be removed and reinserted at any time by means of a suitable tool fitted on its polygonal upper end 35. The lower end '34 of the tube 34 contains a valve chamber 36 having a valve seat 37 at its upper end for a valve 38 'adapted to open and close a channel 39 between the interiorof thetube 34 and said valve chamber. The end 34 of the tube has a slot 40 on one side communicatingwith and' forming'an outlet for the valve chamber. A pin 4l in the valve stem projects into the slot 40 and limits the downward .movement of said stem and preventsl it from falling out of the valve chambenf In the Itube 34 just above the cover plate 12 are a series of holes 42 to admit a hydrocarbon fluid from the casing 14,*which enters said casino through the fluid pi e 43, tothe valve chamber and thence into t e cup-shaped re ceptacle 28 through the slot 40. The stem 44 of the valve38 slides freely in bearings in the valve chamber, and is sufficienti heavy to bear at all times n the bottom o the receptacle 28 and rise and fall therewith as the fioat 25 moves. When the float falls, owing to the lessening quantity of gasolenein the tank or container 1.0, the valve descends with the receptacle and opens communication with the channel 39 and the valve chamber 36, thus permitting gasolene to flow from the the valve seat casmg 14 into the receptacle 28 and thence Vthrough the tubular stem 26 to the bottom of the tank 10. As the tank fills, .the float rises and lifts the valve, finally closing it when the proper level of gasolene in the tank 10 is reached.

One form of the valve structure is shown enlarged in Fig. 4'. In this instance, the

tube 34 ends at the under side of the cove plate 12, and screwed into the end of the tube is a plug 45 containing the channel 39 and formed in a separate tube 46l screwed into the bottom-of the plug 45, or itmay be inte'gral therewith. Rising from the center of the cover plate 12` is a tubular casing 47 within which is placed a rod 48 having an enlargement on its ower end to rest onthe bottom of the receptacle 28, or the screen 29. The upper end ,of the rod 48 is arranged to receive one or more weights49 which by their pressure acting tlirough said rod-and the tubular stem 26, change the buoyancy of the fioat and the height ofthe gasolene level in the tank or container 10, as the greater the weight the higher will such level be. The abillty to change the gasolene level is of advantage, as it enables-the production of gas to conform to-the air pressure and also to the quality of hydrocarbon used.

The upper end of the tubular casing 47 is preferably enlarged or provided with an enlargement 50 to inclose the weights 49, and is closed by a screw cap 51 or other convenient means.
