Application filed March 26. 1905- flerlal No. 281,965.

To all whom it may concern:

Be it known that I, HERBERT A. Boson, a citizen of the United States, and a resident of the city and county of Kalamazoo, State of Michi an, have invented certain new and useful In rovements in Carburetors, of which the ollowing is a specification.

This invention relates to improvements in carburetors.

The objects of this invention are, first, to provide an improved carburetor by which a comparatively even grade of carbureted air or gas may be produced without regard to the quantity; second, to provide an im roved carburetor in which all of the liquid yclrocarbon is utilized; third, to provide animproved carburetor in which low grades of refined hydrocarbon-oils can be used with sat isfactory results; fourth, to provide an irn proved carburetor which although very simple and compact in structure is of largecapacity; fifth, to provide an improved carbureter whichis simple in structure,'econ0=mical to produce, and one which is very durable and not likel to get out of repair.

Further o jects and objects relat' to structural details will definitely appear om the detailed description to follo I accomplish theobjects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embed 'ng the features of my invention is clearly ill panying drawings, forming a part of this specification, in which Fi ure 1 is a, vertical longitudinal sections. view through my' improved carburetor, taken on s line corresponding to line 1 1 of Fig. 2. Fig. 2 is a detaiitransverse vertical section taken on a line corresponding to line 2 2 of Fig. 1. Fig. 3 is a plan view of one of the carburetin -screens, the screen being partially remover? from the frame to show the structural arrangement thereof. F' 4 is an enlarged detail inverted plan s owing details of the trough a. 5 is an enlarged detail view showing one of the carbureting device holders B in position in the carburetor-chamber. sectional view taken on line 6 6 of Fi v5. .Fig. 7 is a detail view showings modi cation, the carbureting devices B being arranged in a vertical position.

- delivery-pipe strated in theacconh Fig. 6 1s a detail In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section-line's, and sinn lar letters of reference refer to similar parts throughout the several views.

Referring to the drawin the carburetorcharnbers A are preferab y rectangular in form and are arran ed in a horizontal posi .tion. These eham are are preferably arranged in series, one above another, as elearly appears in Fig. 1. The chambers are connected, as will be fully described later herein. In the top of each chamber is an oildeiivery trou h c. These troughs are preferably formed y striking u portions of the covers of the carburetor-c embers and sol-' dering a bottom plate over the same, as clearl appears in Figs. 2 and 4. These troughs c extend longitudinally of the chain bers and are provided with a plurality of delivery-openings 0. The delivery-openings 0 at the ends of the trough areconsiderably larger than the delivery-openings o to allow the ready escape of any surplus oil.

The liquid h drocarbon is delivered by the to the trough a' of the upper or top carburetor-chamber. The pipe A is arranged to deliver to the trough a at a central point. The liquid h drocarbon' is delivered from the up or car ureter-chamber to the delivery-troug s of the carburetor-chamhere below by pipes or conduits a. These pipes e" reject upwardly into thechambers a short istance to determine the level of the liquid hydrocarbon therein, as clearly apears froze Fig. 1 The carburetor-chainare are also connected by airipes a. These pipes connect the rear on of each chamber with the toward and of the chain her next above or next in the series. The carburetor-chambers are arr-an ed in alter nate relation to each other, so t at air passmg through them takes a zigzag coursethrough the series. The upperends of these airconnect' pipes a" pro ectshove thencper ends of t e oil-delivery conduits a, so that it is impossible for the liquid hydrocarbail to pass therethrough:

A plurality of carburetingdevices B are arran ed in series in each carbureting-chamber. hose carbureting devices consist of frames i), to which carbureting-screens B are secured. These screens B are preferably made ofsome loosely-woven textile fabric, coarse linen being preferred by me. The carthe same.

bursting devices B are preferably arranged in a forwardly-inclinedposition, as is illustrated in Figs. 1 and 4, and' form a series of comlete partitions across the carbureter-chamhers. These carbureting devices are suported by holders B, into which they may he slipped. These holders are arranged oppositely on the side walls of the carbureterchambers. (See'Figs. 2, 5, and 6.)

The bottoms of the carbureting devices rest on the bottoms of the carbureter-chambars or at least extend below the lane of the topof the conduits a, so that t ey extend intothe liquidhydrocarbon. Interposed between the tops of the carburetingdevices and the tops of the carbureterchambers are layers of.fabric bf, which serve as conveyers or distributers forrthe. liquid hydrocarbon delivered from .the troughs a. The liquid hydrocarbon is .thus firstdelivered to the upper edges of the .carburetingsscreens and by gravity andalso b 'capillarity soon spreads over 'VV hen the screens are saturated, the surplus isdelivered to the bottom of the carbureter-chambers, and it is intended t at the bottoms of the chambers shall at all times be covered by the li uid hydrocarbon to a slight depth,-preferab?y about one-quarter of an inch. The. liquid hydrocarbon is also carried up by capillarity from the bottom of the carbureterechamb'ers, so that the carburetin -screens areke t thorou hl saturated at al times, as this resh supp y 1s delivered to the upper end of the same in quantities sufiicient to compensate for that which is taken up by the air assing through the carbureter.

The air is elivered :to the forward end of the lower carbureter-chamber by the air-supply pipe C and-is forced through the carburetmg. devices oi the lower carbureter-chamber to the ipe a, throu h which it is delivered to the orward end 0 the second carbureterchamber, through which it-passes to the top carbureter-chamber and is delivered from the rear end thereof by the gas-su ply pi e C.

The air passing through the car ureterchambers is brought into contact with the liquidhydrocarbomwhich is held by the'carbureting-screens -13 of the carbureting devices, so that lit iS vereffectively charged. As the screensare at a ltimessaturated, the quality of the gas remains comparatively constant no matter what quantity may be used. The quality of. the gas or earbureted airis also. good .from the firststarting of the carbureter.

The sereensB are tightly stretched upon the frames band'are preferabl secured thereon b sewing. Cross-pieces are provided for t e frame I) to prevent the sagging of the screens and also to make the framerigid. By thus constructing the sameiit can bemade of comparatively. light wire. B arranging the troughs aas thave illustrate .the oil is deliveredtc the distributers b at intervals along the same. The oil is carried by these distributers by capillarity, so that it is distributed to the upper ends of-the carbureting devices u on which it rests. As the ed es of the car ureting-screens B are wrap ed over the frame they are brought into pe ect contact with the distributers b, so that the li uid hydrocarbon is delivered thereto by capi larity.

I preferably arrange the carbureting devices B in a forwardly-inclinedposition, as is clearly illustrated in Fig. 1. Desirable results may, however, be secured b 1 arranging them in a vertical position, as is illustrated in the modified construction shown in Fig. 7. In order to secure satisfactory results, it is desirable, however, that they should form complete artitions from the top to the bot tom 'of t e chambers-that is, that they should extend into the liquid hydrocarbon in the base of the carbureter-chambers and be positioned to receive the oil at their upper e es.

lNith the parts arranged as I have illustrated and described the carbureting devices present a minimum amount of obstruction to the passage of the air, so that only a small amount of pressure is required to force the air therethrough. I am enabled by m improved carburetor to use the lower gra es of ydrocarbon-oil and secure practical results and to utilize ractically all of the same. My improved car ureter is very economical to produce and is compact and simple in structure, and the device is of very large capacity in roportion to its size.

Fhave illustrated and described my imroved carburetor in detail in the form preerred by me on account of its structural simplicit and economy. I am, however, aware that it is capable of considerable variation in structural details without departing from my invention.
