IMPROVEMENT 1N CARBURETJNG APPARATUS.

The Schedule `referred to in these Letters Patent and making part of the lame.

To all whom it may concern Be it known that I, JOSEPH' MILLWARD, of Fayetteville, in the county of Onondaga and State of New i York,l have invented certain new and useful Improveluents in -Garbureti'ng ApparatuA aud I do hereby declare the following to be a full, clear, and enactI description of the construction and operation of. the same, referenceI being had to the accompanying d rawingsmaking a part of this speciiication, in which- Figure l represents inperspective the exterior of the apparatus; Figure 2 represent-s, on an. enlarged scale', a vertical section through the carbureting apparatus; and -Figure 3 represents, on a similar scale, a section through the air-driving wheel, taken at right angles to its axis, and showing its form ot' buckets. Y

Similar letters of reference, where they occurin the separate iigures, denote like parts ofthe apparatus in all of thel drawings.

My invention relates mainly to the construction and operation ofthe air-drivingwheel, the open chamber, in

-which it works, the closed chamberadjoiniug, with a water-packed communication between them and a carbureting-passage or chamber, vmade between concentric and alternate shorter and longer cylinders, as Will be explained. y

lhe base A of the apparatus is divided by the partition (l, extending from vthe top to'near the bottom thereof', into two chambers, B @having a water comlnunication with each other underneath the partition a, as selen at 11.'l

Lhe chalnberB is open to the .exterior air by means of the openings c c, or through a well, d, and in this chamber, `partially .iilledwith water, is placed the airdriving or propelling-wheel 1),'conx posed of buckets e c, Ste., ot' peculiar form, and which, when revolved by anyordinary power, take inthev air at f, and, as the wheel continues to turn, discharges it at g, and b'elow'f the center of the wheel, whence it is driven through the tubular axis l1, and into `the chamber C, which is a sealed or packed chamber.

lhe peculiar forni given to the buckets ofthe airwheel is for the purpose of making the 'end f, where the ail' is taken'in, descend far-enough into and below the surface of the water, designated by the line t', to perfectly seal that end before the other end of the same-bucket rises above the surface of said water, and prevent lany escape ot' air' at thel inlet end. Or, in other words, the air is forced in under pressure, and the inlet ends 'must be snliicient-ly sealed by the column of water above them to stand the pressure without allowing theair to escape therefrom. v When the air-wheel-Dis. not revolving, the vWater in the chambers B C will 'be' of uniform height.` But -when the wheel is started, the air' is driven through the buckets e and into'the chamber C', with consider,- able force, and with suiiicient force to displace some of the water contained in said chamber, driving it through the passage b, into the chamber 13, andcorrespomlingly raising the water therein; and the tendency of this waterin B to flow back again, or to find its level, andthe resistance ofthe compressed air together, makc, as it were, a regulator for the flow of the air through the fcarbureter, and making its How uniform, instead of in beats or pulsa-tions.

From the chamber O the air is forced, up through vthe'tubek, and through and around and over the se ries of concentric passages Z l l l I, each :alternate cyl-l inder or jacket, as at m, vbeing shorter than those next to them, soa's to form a long continued circuit of the airthroughand in contact with the vapor ofthe carburetin'g material, which, together ivith the concenf Atric cylinders and passages,is inclosed in a tightjackety or case, E.

The carburetiug material is placed in the bottom of the inclosed'casc E, alld rises therein to about the height shown atj.

Above the hydrocarbon, and through the concentric rings, cylinders, or jackets, are made a series o f air-holes, a n, and inthe air-passages between these jackets is placed any absorbing or vapor-containing material, o, through which, and-through the Vapor it contains, the air must be forced or pass, before it reaches the interiorchamberF, whence it is conducted; Vby one or moretnbes, p, to the burners.

The tube q carries oit' all excess of the hydrocarbon above the linej. A

The pipe rr is for drawing off the contents of the cylinder, when necessary for any purpose to do so.

The holes s arefor allowing the v apcrizing mateterial to flow through, so as to occupy the under portions ofthe air-passages.

The buckets e e of the air-forcing` wheel are sepa rate and independent ofeach other, as seen in iig. 3.

They are nite dee 4at their centers and very shallow at their inlet and exit, and so shaped as to dip` deeply -in the water, tomore thoroughly s'eal their ends, andso exert greater pressure upon the 'air carried through them.v

That 1.clai1nis In combination with a blowing-wheel and its appli vances, the carbpreting-chamber E, composed of a s eries of concentric rings or cylinders, through, over, and between which the air to be carbureted passes in con tact with the 'carbureting vapor, substantially asand for the purpose described.
