To aZLw/zom it concern:

Be it known that I, Gus'rar JOHNSON, a citizen of the United States, residing at Chicago, in the county of Cool: and State of Illinois, have invented certain new and useful Improvements in Carbureting Ap 'paratus, of which the following is a spccifition, strong, durable and eiiective in opera.

tion, the parts of Which shall beso made and arranged'x vith respect to one another that a very small quantity of gasolcnc, which as is well known is highly explosive, will be contained in the machine and on the premises,

yet it will be automatically supplied through the macliinein suificient or the. desircd.q-uan-- tities for carbureting.

, Another object of the invention is to provide improved means for cl'iarging air with thevolatilized hydro-carbons to the end that illuminating carbureted air of the highest uality may be reduced or afl'orded, and so t aifl it may he eliveredj to thcservic'e pipes in aidry and pure condition and as required.

I Numerous other objects and advantages of. the invention will be disclosed in the sub- .joined description and explanation.

. In order to enable others skilled in the art to which iny invention pertains, to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which Figure 1 is a ve-rt-ical central sectional view of a carbureting apparatus embodyin the invention;- *im 2 is a sectional view ta ten on linc'2-2 ot Fig. I'. looking in the directionindicated the arrows, showing a part otthe water tank and the air feeder or compressor located thercinyFig. 3 s a r'earend- View of the machine; F155. 4 is a front viewthereo Fig. 5 is an-en icw of a; ort'ion jo h irream or con'iprcssor,

. Like numerals of reference, refer to corresponding parts througl'rout the diflerent views of the drawings.

' The reference numeral 15' designates a tank which may he made of any suitable size, form and .i'na'terial, but preferably of.

metal and: with its loner portion semicircular in shape. This tank. may be mounted on supports 16, one of which is located nearend of a shaft 18 which ishorizontally and longitudinally located in the. tank and has its other end fitted in one end of a sleeve 19" which is rotatably mounted on a tubular shaft 20 which is journaleil in the opposite end of thetank from that to wlfiich the bearing 17 is secured. Extending from-the slccve'1'9'a nd' communicating with the cavity: thercof is a tube 21 Which has-itsfreeen'd" open, as will be clearly understood b reference' to Fig. l of the drawings. 'ou'ntc'd" on the shaft 18 near each of its ends is'a! disk 22,,e'ach of which is provided with a scri'es of radial slots 23 to receive partitions 24 which. are radially disposed w th refer'- ence to the shaft 18 and in'su'ch a'nnai'n'rcr that their inner edges will be located at a slight distance from said shaft. Each of the partitions 24 has at it's ends opPosit-cly extc-nded wings or flanges 25 wine 1 will overlap each'othcr', yet 'w i ll be slightly spaced apart so as to permit the passage o'tl'a-ir' compartments 26 formed by the partitions. Surrounding thepartitions 24 ands'ecuredto th'eir pc' inents 26 between the flanges 25st sai end of the cylinder, it will be caused to enter the tube 21 and pass from the same into the airometer.

By reference to Fig. 1 it will be seen that the cylinder 27 of tie air feeder or compressor, which is-designated as a whole by the reference numeral 29, overlaps the. ends of the partitions 24 adjacent to the tube 21,

' thus formin a chamber between the end 28 of the cylin er and the flanges 25' adjacent thereto. The rear upper portion of the tank .;l is'pr0. vided with a cover or housing 30 which extends to. about the middle thereof and ha jour'naled on its up er front ortion .one en of a shaft 31 the ot er end 0 which, is journaled on a support 32 secured to the front portion of thetank. This shaft has mounted thereon a drum 33, and is provided at its outer endwith means '34 to engage a crank when it isdesired to turn the drum in order to wind up the cable 35, which is secured at one of its ends to the drum and passes over a pulle 36 suitably journaled on a hanger 37, an has at its other end a weight 38 to actuate the drum 33 and through it and its gearing the air feeder 29. Mounted on the shaft 18 near its front end is a gear 39 which meshes with a gearAO on one side of the.

, end of a pitman 4'9 which'is pivotally con nected at its lower end to a piston-rod which is pivotally secured, at its lower end to a piston fillocated in a (pump cylinder 52, which 'pumpor cylin er communicates through a coupling 53 with a valve-casin 54' which-is provide with a series of v-a veseats 55 and 56, each having a, valvefi'? and 58 respectively. 1 By reference to. Fig; '12 it will be se'en t at the valve-se'ats5'5 are arranged below the support '53 which communicateswith the pumping c linder '52,

" while the valves 56 and seatsterefor are,

located above the same.

The lower portion. of the vvalvecasing 54 has communication'through a 59 with thevgasolene tank 60 which may located at any'suitable" point and at any distance from the machine or premises, and usually below the surface of the.ground for the the cover 300i the water tan at portion ofthe carbureter hasleadingtheresake of safety against explosion. f The up per portion of the valve-casing 54, has coin- "niu'nication through a pipe 61 and "a coupling 62' with ,the carburetor 63,- which 1s" ortion of,

zanyiisuitl amen) from a pipe 64 which also communicates with the gasolene tank 60, and is for the purpose of conveying the excess of gasolene or oil to said tank.

As is clearly shown in Figs. 6 and 7 of the drawings, the carbureter consists of a vessel of any suitable size, form and material, but preferably of metal andi'rectangw,

\poztion an lar in shape, and has in its uppe inlet opening 65 for the supply air thereto, as well as the opening or'coupling 62 for the admission of gasolene. Located within the receptacle 63 are a series of battle-plates or. shelves 66 whichare alternately inclined in opposite directions, as

shown, and each of said plates has its free end upturned as at 67 to'form trou 'hs or receptacles to prevent the gasolene' tibwing from said shelves or lates too rapidly, for it 'will be understood that said plates or shelves extend from one side of the receptacle 63 to the other side thereof and alternately from one end of the receptacle to near the other end thereof, thus roviding s aces between the alternate en s of the s ielves and the ends of the receptacle; 1 Each of the shelves 66 is supplied on its upper surface with a quantity of absorbent ma terial 68, such as felt, batting, asbestos or the like, to absorb and retain gasolene;

Suitably mounted near thecarburet'er 63 whole by the reference numeral 69, and which consists of a vessel70 having its u per end open and provided with a spout 1 through which water may be passed to said vessel. The bottom of the vessel 70 has communication through a .pipe 72 and a coupling 73 with the tubularshaft 20 of the air feeder, and said coupling may be rovidedwith a valve or cock 74 for-the ischarge of water. Extending upwardly from the bottom of the vessel 70 and communicating with the pipe 72 is a tube 75 which has in its upper end a valve-seat 76' for the valve 77 on the lowe end ofiarod 78 which depends centrally from the to of a tank 79 which has itsbottom open an is movably located in the vessel 70 so that the open end thereof will be se'aledby .the water contained in said vessel; The ower end of the tank 79 is preferably provided with weights 80 secured thereto in an suitable. manner. Communicatin Wltl the lower portion of the receptac e 70.0f the airometer and usuall throu h the bottom is an airometer', which is indicatedas a thereof 'isa pipe 81 w ichleas to'and co1n 'municates through. the coupling 65.

Thefilteror mixer .84 1s su plied with a quantity of asbestos, exceslor 85, or other suitable material, and )per end a service-pipe 86 which may lea to the various points atwhich gas is desired.

From the foregoin and by reference to the drawings it will %)6 readily understood and clearly seen that, by 'su iplying water to the tank/15 which may be one through a supply pipe 87 located in one end thereof i so that the water level will be at a point above the shaft 18, the air feeder or compressor 29 may be caused to'rotate by reason of the action of the weight 38, the cable 35, drum 33 and *earing between the shaft of said drum and the shaft 18 on which the air compressor is mounted. In this operation it is apparent that in the rotation of the cylinder 27 air will be caused to enter the con'ipartnients 26 of the compressor above the water level and between the flanges :25 at that end of the compressor adjacent. to the pum, As the compressor cylinder rotates fart ier it will be understood that the air will pass from the compartment which is l being, submerged into the chamber of the cylinder at the cnd thereof in which the, tubeQl is. located between the flanges 25 and said end, and will be' caused to enter the tube 21 andto pass therefrom into the air-' ometer.

In the foregoinp operation the piston Ill of the pump will be reciprocatcd. thus alternatel v opening and closingthc valvcs ST and 5%, thereby drawing gasolcnc from the tank (it) through the pipe '51! into the valve-casing 54, and from. thence through the pipe 01 into the-top of the carburetor where -it will fall onto thc upper battle-plate and pass operation it will be suspended b v reason ofthe tibstlllltflt material located on said plates cnd'that' evaporation only air from the aironn-ler will at the same time be supplied to th carburetor througlrthe pipe 51, which, as before stated, leads from It is evident that the pump will be driven thrt'iugh the instrunh-ntality ol the gear 40, pinion 4 pitinan it) and piston 51, which parts are actuated bv the weight 38, cable drum 1?

As the free endof each of the l'mlllc-platcs fit, is upturned to provide a trough on each of the shelves, it is apparent-that the liquid will be held thereon so as to keep thc'abso'rbcnt material saturated, -.but'that the surplus liquid will pass over the upper parts of said upturned portions from one shelf to another until reaches the bottom of the receptacle. from whence it will pass through the pipe 34 back into the tank 6U or. source of supplyfan' thereli'y prevent wa te of material, and by this continuous p- '.:age of the gusoleit' avoiding po.--sibilit of t'XPlUSlUHStttl the premises.
