Be 1t known that I, CHARLES E. WVHITE, a

citizen 'of the United States, residing-atfSan' Francisco, in the county of San Francisco, State of Cahfornrmhave invented a new and useful Carbureter, of whic'hthe following is` a specification insuch tullr and clear termsvv vas'will enable those skilled Vin thefart to con-.

struct and use the-same. 3:" Y This invention relates to a vaporlzer for oil and its object is tov produce a device which is capable of supplying anexplosivev vapor to internal combustion engines vfronr j heavier oils than are usually used for thatpurpose, heat' beingy used t'or increase the vaporizationoi' the oil.

Another object of the invention is to pro-- vide a carburete-r wherein almost any liquid f hydro-carbons may be successfully employed as fuel for internal combustion engines, such 1 as kerosene oil, 'diiferent gravities of distil- I .which is capable ofbeing secured on the in late (heavier than gasolene), tallow or lard 'I oil, or crudepetroleum oils freeffrom-fas phaltum.

y l f Another objectof the invention is to prof vide 'a carbureter wherein the-properamount of oil vapors are generated bv the exhaust heat of the engine anda suitable amount of y air admitted by the inspiration of the engine to Aobtain a proper combustible nurture, from the fact that the oil vaporfandair are controlled from one lever movement similitaneously. v

Other objectsiof the invention will as the description proceeds. A

Anembodiment of the invention is shownl in the drawing in whichlthe same reference numeral is applied to "the same portion appear throughout, but I am awarethat there may [be man v modifications thereof.

,Figure 1 is` a vertical sectional view -through the complete vaporizer, Fie'. 2 is, a'

horizontal sectional View on the line 2'2, Fig. 1, and Fig. 3 is a side elevation ofthe Wick holder.

The numeral 1 represents a flanged fitting let pipe of the explosionengine, said fitting being provided with a downwardl v eritend ing boss 2 threaded t' receive a circular member 3 which forms a 'chamber surrounding a'tube 4. Thechamber 3 has a pipe 5 connected therewith on one side and a pipe 6 on the other side, which'pipes are suitably connected with the exhaust vpipe of the encHARLEs E; Winrnonsisir rizancrsco, museums; v i

gine. Thexoil receptacle'is 'formed-of the cylindrical tube e ywhich is forced intothe chamber 3 and a tube l" extendingthereinto through a closure ,oul the lower end of said oil receptacle.k The tubef is vopened-:u1 the top and closed at the bottom and is'provicled with a, plurality of triangular openings 3 in its sidefadjacen't thebottom. u .g l I They tube f( is smaller in dianieterthanthe tub'e4 and forms therewith the o il and 'wick chamber. Connected with. the bottom ofthe tube 4 isa pipe 9 carrying an 'elbow'l to be connected therewith forthe supply of,A the oil. In the space between-fthe(pipe' Fifand wallf'of the tube il, a cylindricalr wick 1'1 is placed. 4 Thlswick 11 is'cari'iedlbyfa,cylindrical metal shell 12 supported from a valve vrod lfand it is'provided with anvr outer shell 15 so that the wick will not stick against the wall of the tube l when it isbeing moved up and down, The oil is suitably` regulated to standaboutthe level of-.the dotted line 4,-4 byfany improved means not axpa'rtbf this invention.

The shell forming thei'wick support is providedwith a large number .of perfora-l tionsasindica'ted at 16 tov allow the oil to haveaccess to the wick and with top perfo- `rations to allow the air to pass therethrough. Slidable within the tube 7 is -a cylindrical kvalve 17 .for covering and uncovei1ng,the

openings 8, .said valve having a conical top 18 provided with a plurality of openings 19. The valve 17 is supported on the lower end of the rod 13 and the upper end of said rod is connected with a suitable bell crank lever 20 by means' of the pinQl working in a slot in said bell crank lever. The bell crank lever is supported at its corner ori a lug' 221m the casting- 1 and a suitable rod 23 enables the operator to shift the position of the valve and wick as ma)7 become necessary to cause mere or less oil vaporization andto increase or rliminish the vair supply to insure a perfect combustible mixture,v Surrounding the tube 'just below the chamber 3 is an electrical heating element 2li, the current being delivered thereto by means of the inlet wires 25 and 26.

The operation of the deviceis as follows:

Vieu i Nhen the engine is about to be started cur y will be heated to such an extentvasto vaporize the oil, whereupon the engine may be .heating supplied with the explosive -inixture by openinfbir the valve 1T by the operation of the rod Q3. As soon as the engine has started the heat iiroln the exhaust ,eases will heat the tube i and as the valve 17 is opened the Wick will litt a. supplj,Y of oil into contact with the hot part oi the tube 4 and therebf,7 supply the nemesisarjvv v 'lor to drive the engine, at which time the current may be turned od the heater Q4.

An advantage o1"- the foregoing construe tion lies nthe tact that the air valve sup plies very aceurateij,r the aniount oi air nec-- essary to the proper combustion of the oil lifted by the iviclt into contact with the hot surface of the oil tube.

Another advantage ot the 'foregoing con' struction Aliea in the fact that the exhaust heat iroin the engine utilized 'for vapor-izine' oil heavier than tgasolene and the siinple adjustment et the application of the oil to' the heated. surface, together with the adjustment oli the proper amount of air with the vapors to secure highly con'lbustible mixture, as the oil vapors are given oii' and the admission of air being adfusted at thc same time by one lever, eliminating the needle valve and numerous levers and valves.

Having thus described my invention what l claim as new ters Patent of the United States, is as tot lows, lnodiications within the scope oi the claims being' evpresslvv reserved:

1. ln a tairbineter, the crnnbination of a .heating chamber, a receptacle located below and providing a passage to a wall oi said chamber, a wich niovabl)7 mounted within sa id receptacie a ed adapted to convoiT oil into direct Contact with the outer surface a wall ot said heating chamber, means ior eupplyi air to the oil vapors, as generated, by said heating.; chamber, to obtain a highly explosive mixtureT means for continuand desire to secure by Let-A invaaee ally heating,r said chamber, and means to supply oil to the ,wie t.

2. In a carbureter, the combination of a tube, heating means surrounding a portion of said tube, an annular wick movably mounted within said convey oil into direct contact with the heated portion of said tube, and means to supply oil to Said wick.

3.

Ll. A carbureter con'iprising a cylindrical receptacle, a'chainber surrounding the cylindrical receptacle at the upper end thereoi', means :tor heating said chamber` a wiel; mov'- ably mounted within the cvlindrieal recep tacle for bringing oil in direct contact with said chamber, a cylindrical air supply tube extending within said cylindrical receptacle, and having openings therein at its lower end, below the oil chamber, a valve in the cylindrical air eupnplj,Y tube and a rod con necting the valve with a carrierby which the valve may be opened and the wich raised simultaneously.
