' APPARATUS FOR rnonucme unseen-man AIR.

To all whom it may concern:

Be it known that I, RICHARD Boson, a subject of the German Emperor, residing at Hanover, Germany, have invented certain new and useful Improvements in Apparatus for Producing Carbureted Air, of which the followingis' a specification.

This invention relates to improvements in apparatus for producing carbureted air.

By the improved apparatus gas of the highest degree of purity and of uniform composition is produced. The term gas used throughout the specification is used to indicate the mixture properly speaking of vaporized gasolene and air.

In the improved apparatus the liquid to be gasified is conveyed in a continuous jet to the carburetor proportionally to the action of an air compressor. The carbureter is so constructed that the air causes the liquid distributed therein to take a centrifugal and centripetal path. This is efiected by means of a series of nozzles arranged for the entry of the air concentrically about the gasolene jet and discharging in oblique or tangential directions. 1

The air to be carbureted is-contained in a suitable reservoir and is brought to the pressure at which it is used by means of the air compressor which is of suitable constructionnism or motor. Means are provided whereby if the pressure in the ca-rbureter becomes too great the action ofthe air compressor is retarded or stopped. 1

Referring to the annexed drawings, Figure and actuated by a. suitable driving mechalis a section'o'f the carbureter in connectionwith the compressor. Fig. 2 is a vertical section through the'sprayingnoz-zle suppl ing compressed air and gasolene'to "thecarandFig, 5-is a detail of the mechanism on top of the member 18 of Fig. 1.

The gasolene distribu'ter consists of a chamber 18, 'inwhich'a piston 19 is ada'ted to-raise and lou-e1-tl1e:l.e'vel of the gaso-eneat theYWi'll ofithe operator, and, by the following described mechanism; viz-z-said pist-on'is of smaller diameter than theinte- 'rior:offthe chamber. .Therefore when it is pressed down,- the-gasokne forced up Specification bf Letters Patent.

around its periphery and finds vent through the opening 20; and, when the piston is 1i 1;- ed, the gasolene recedes and theflow, at 20, ceases. Said piston is provided with'a rack 24, which engages a toothed wheel 23, on a shaft 28', on which is loosely mounted a Worm wheel 23, and having a hand crank secured thereto. A means is shown at the crank, so that it will rotate with the shaft 23". Said worm wheel is actuated by a Worm23, which is driven by the toothed wheel 50, the two wheels being keyed to the same shaft, and the latter one meshing with a wheel 51, which is keyed to the same shaft as the Wheel 53. The, latter is drivenby flexible transmission means 52,. from the wheel 54 on the shaft 55. Said shaft is driven from any ordinary source of power, through the medium of transmission means, shown at 54, 543, which actuates in addition to the mechanism described, a gear means 56, 55], by which ,an air con1press'or12 of ordinary type is actuated. Keyed to the shaft which carries wheel 57 is a brake drum purpose hereinafter statedj By the mechanisms described in, the foregoing, the air compressor and gasolcne 'feed'are at tuated simultaneously; the piston 19,'being gradually 10w red by means of the rack 24:, and the gearing associated therewith. When it is desired .to refill the chamber 18, the thumb screw 25, is disengaged from the worm W'heel'sov that the shaft 28 ma be ro'-. v

The p tion of gas is thus -,.as uni-form: as' p and any tem orary or periodical change in the gas pro notion is obviated by the infiowing air being only supplied with that quantity of gaso ene with which it can be 5 easily and properly mixed.

The gasolene or the like fed out of the chamber 18 by the piston 19 flows through the pipe 21 direct to the carbureter chamber 22 andis dischargedcentrally therein through the pipe 21' passing through the air nozzle 34.

.The carbureter here illustrated consists. of. the chamber 22in which plates 32 are arranged concentrically above one another "which are alternately of circular and annular shape so that the air current asses alternately over the eriphery 0 one, and through the annu ar aperture. 32 of the next and so on. The air from the compressor 12 passes through the pipe 33 into the nozzle 34 provided with concentric series I of apertures 34arranged obliquely or tangentiallyin such a manner that the air currents are discharged therefrom obliquely '25 onto the uppermost plate 32 so as to set up a rotary air current or vortex and the gasos lene flowingout centrally at' the same time through the ipe 21 onto the said plate 32 is centrifuga y distributed over the plate and is driven centrifugally over the same on to the plate 32 immediate'ly'below passing thereover centripetally and through the central annular aperture of the following plate and so on until the vaporization is complete.

' The number of plates is according to the chiciency required of the carbureter.

he particular advantage of the carbureter consists in the fact that the freshly introduced air immediately encounters fresh 40 'gasolene on;the uppermost plate-and from the inlet to the outlet travels in the same direction as said gasolene which is necessary for pro ucingan-even mixture; -The rota direction of the air" currentspreventsthe 'gasolene from'flowingin, radiallines overthe plates whichwould not .afl'ord. a,sufli.'

cient y large operative surface to said air;- currents. The outlet of the carbureteris, also,-

float can be adjusted for any desired margin between the normal pressure and that at which the brake is to act. The advanta e of providing this margin is that the bra e need not act continuously andthe resistance of the compressor, which increase'swith the increase of pressure, may be fully utilized Within this margin without the pres sure regulator of the outlet main bei'ng' actuated orinfluenced. The airunder pressure in the compressor 12 passes through the pipe 33' into the carbureter 22 as aforesaid and from the latter through another pipe 36 into a cylindrical chamber 38 divided into an outer and an inner compartment 38 and 8,0 38' respectively by an annular partition 37. A. liquid in the chamber 38 forms a seal between said outer and inner compartments. In the inner compartment is located a float 39. If the, pressure rises above a certain point the said float is immediately lifted thus breaking the action of the compressor by means of a system of rods 40 and a band I brake 41 acting on a drum 41 on the compressor shaft. The latter may be driven'eo wheels 56 and 57. When the pressure falls the float sinks and releases the brake acting on the compressor. Byadjusting the weight of the float and the braking mechanism-4:1 'the'brake may be regulated to operate at any pressure.

A disengagingdevice of any suitable kind for the motor (not shown) may be arranged at any convenient position on the apparatus; For instance a friction clutch arranged in the driving gear, or an ordinary belt shifter couldbeused What I claim as my invention and desire to secure by Letters Patent of the United States is 1.
