EDWIN' G. v s'rAUDE, oF MINNEAPOLIS, MINNESOTA.

Application filed January To all whom t may concern.'

Be it known that'LEnWIN G. STAUDE, a

citizen ofthe United Sta-tes, resident of Minneapolis, in .thecounty-of Hennepin, StateV 'of yMinnesota,l have .invented certainnew and l f useful' Improvements -in Vaporiz'ers, of:

which the following is a specification.

.Therobject of my invention isto provide means for amore thorough vaporization of the oil and a more complete Carburation of the air in the mixing chamber of the carbureter.

A further object is' to provlde a carbureter in which the feed of the oil is regulated by the movement of the air valve. 'i

A still further object is 4to provide a earbui-eter' which will be composed of but few parts and be simple and :positiv-e in its action.l

The invention consists generally invarious constructions and combinations, all as hereinafter described` and particularly point ed out in the'claims. In the accompanying part of this specification,

Figure ,11 is'V avertical sectional view of. a. carbureter embodying my invention. a

Fig. 2 'is a detail'l sectional vievv, showing al modified form of retort.

In lthe drawing, l2 .represents the lower portionofthe "carbureter casing and f3 the drawings forming upper portion, containing a mixing 'cham-- ,gber L and the usual throttle valve 5. These V'sections are Vsecured 'together by suitable 'means, Vsuch as lugs-or ears. 7 1s the oil supply duct, communicatingtvitha .sleeve 8 mounteipreferably on the wall of tliecasing l 2 -andhaving a guide 9 for a needle valvelO that is adapted toclose the port 1l provided `to in a nozzle12 which projects into a chamber 13v formed Within vthe casing '2. The valve 10 has arduct- 14 therein leading to a transversel passage 15 in'said valve, which connnunicates preferably with a space 16 lformed Within the nozzle 12 inthe rear ot the 'discharge port 11;-5 A spring 17 normally holds theralve in its-closed position.

'Y A` plunger 418- iswniounted to `slide in the in- `ner end of the nozzle 12 and rinthe lopposite .59

wallofthefcasing 2 and is adaptedto coni tact with theslinnerfend of the-needle `valve 4to force it opengagainst thecompression ot .thespring 17. "When this; valve is opened,

the oil will-Hou'- into the duct llaanfdthe passage 15 and from thence'to the discharge .porty l1 and vdropupon a shelf or -lip 19 that specincatin or Letters Patent'.

is 'preferably formed ou the nozzle beneath the port 11. This shelf operates to spread the oil'over the surface of the retort beneath'. In the lower part of the chamber 13 I preferto provide a retort., wherein the oil is vaporized as it falls by gravity from the shelf 19. The preferred form of this retort I ivill nouv describe 'in detail.

20 is a block, preferably of porcelain or other suitable non-'conducting material, haw ing a depression 21 in its upper surface and a series of Wires' 22 embedded in the blocir.A at suitable intervals and forming a resistance coil in circuit with the electric conducto and .24 which communicate with a ba or any other suitable Vsource ot elect-ir energy, not shown. Between this block and the Wallsof the casing 2 I prefer to provide a lining 24 of-asbestos-or equivalent material.V The 'ivires 22 are sutlicient-ly smal to form a resistance inl theblock and create sulicient heat to va'porize the oii as it falls into the depression 21. the degree of heat .being regulated by thefintensitv of the elcctric. current. i The upper portion of the chamber 13 communicates with the mixing chamber #L and into this chamber the vapor rises ,and meets the air currents entering the chamber through the annular passage This passage'isnormally closed by avalvc ring 26 which rests upon the upper wall of the casing 2. `Parallel arms 2T and 2S are 'pivoted centrally'on the valve `ring 26V at their inner ends While their outer ends'are titi the Casing The loiver arm 2Q, has an ex- @tension 30 thereon thatl is adapted to slide Vinthe forked upper end Otan arm 31 which "is pivotally connected at its louerend to a .block 32. This block is interiorlv threaded i toengage the threads ofa screw 33 thatis mountedin upright bearings ou the vvall of the casing 2 and is provided with a finger grip 31 b v means of which the screw maxY he revolved' and the block raised or lowered.

thereon. The plunger 1S projects o.utvardl' \v into the path ot' the arm 31 und evidently the stroke of this Plunfrer will he varled according to the distance ot the pivot of the Lowering thls arm 31-t`rom the plunger. l pivot will increase the stroke. ot the plunger, While raising it will decrease the stroke ot'the plunger.

On the suction stroke of the engine. the valve 2i.'- will be lifted from its seat and the currents of air rushing in will form a vortex ahme the chamber 1B, into which.' the vapor from the retort beneath ,will be sucked and tle'i'fimghly u'iixed with air befljiro-ent'ering es-lgiuo cylinder. The valve will rise, and

"u 'the operation of the engine and its efetrolfe of the plunger, and, as before ated` :this Stroke can be alccu at'ely c011- Lrollel'l by the adj uetmeut of' theiblo'ck?.
